Abstract

PROBLEM TO BE SOLVED: To ensure economical operation by constantly monitoring operating conditions without spending extra time or manpower. SOLUTION: An operation monitor circuit 12 automatically forces an engine into a shutdown state as soon as a parking brake is operated into a parking position or after a predetermined period of time has elapsed while a vehicle remains stationary. This helps prevent fuel from being wasted while the vehicle remains stationary. In addition, this device determines the current operating mode and causes an alarm buzzer to sound when an engine speed or vehicle speed reaches a predetermined value corresponding to a normal-speed mode while the vehicle is running on an ordinary road (normal mode), and when the engine speed or vehicle speed reaches a predetermined value corresponding to a high-speed mode while the vehicle is running on an expressway (high-speed mode). This allows engine speed and vehicle speed optimum for each current operating mode to be retained, which ensures both economical and safe driving.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle operation monitoring apparatus for monitoring a driving condition of a vehicle to perform fuel-saving driving.

[0002]

2. Description of the Related Art In recent years, in the transportation industry or the like that uses a large number of vehicles such as trucks, it is important to implement fuel-efficient driving in order to reduce exhaust gas and fuel cost in view of environmental problems and management costs. It has become a challenge. Since the fuel-saving driving often depends on the driving method of the driver who actually drives the vehicle, it is necessary to give attention to the fuel-saving driving to the driver himself. For this reason, conventionally, a tachograph is mounted on a vehicle to record the operation status, thereby encouraging the driver himself to save fuel and drive safely.

[0003]

However, tachographs require extra time and manpower because the manager / supervisor needs to periodically check the records and provide guidance and education to the driver based on the results. Is required. In addition, since the driver cannot pay attention during driving, there is little effect of thorough fuel-saving driving.

[0004] The present invention has been made in view of such circumstances, and accordingly, an object thereof is to constantly monitor the driving state and implement fuel-efficient driving without requiring extra time and manpower. It is an object of the present invention to provide a vehicle operation monitoring device that can reduce exhaust gas and fuel cost.

[0005]

In order to achieve the above object, a vehicle operation monitoring device according to a first aspect of the present invention comprises a vehicle stop determining means for determining whether or not a vehicle is stopped, and a parking brake for moving a parking brake to a parking position. Parking brake position detecting means for detecting an operation, when the stop determining means determines that the vehicle is stopped, and when the parking brake position detecting means detects that the parking brake has been operated to the parking position, immediately or The engine is forcibly stopped by the engine forcible stop means after a lapse of a predetermined time.

With this configuration, when the parking brake is operated to the parking position while the vehicle is stopped, the engine is forcibly stopped immediately or automatically after a lapse of a predetermined time to prevent wasteful fuel consumption during the stop. Therefore, fuel-saving driving can be reliably performed without spending extra time and manpower on guidance and education. In this case, since the stop of the vehicle and the operation of the parking brake are the conditions for forcibly stopping the engine, malfunction of the forcible engine stop system can be prevented.

In addition, if the engine is forcibly stopped when the stop time is short, the demerit due to the emission of harmful gas upon restart is greater than the effect of reducing the exhaust gas due to the stop of the engine, and the stop time is short. The restart operation must be performed every time, and the drivability is impaired. However, in claim 1, only when the parking brake is operated while the vehicle is stopped, that is, when it can be determined that the stop time is prolonged. As a result, the effect of reducing the exhaust gas due to the stop of the engine can be surely increased more than the disadvantage of discharging the harmful gas at the time of restart, and the operability is not impaired.

In this case, when the key switch is operated to the off position during the forced engine stop, the forced engine stop state may be released to enable the engine to be restarted. This makes it possible to easily release the engine stop command and restart the engine by operating the key switch.

According to a third aspect of the present invention, the driving mode determining means determines which of the plurality of driving modes corresponds to the driving mode based on the engine operating state, and the engine speed corresponds to the driving mode. When the number of rotations becomes equal to or more than the predetermined number of revolutions, the alarm control means may cause the alarm means to perform an alarm operation. In this way, when the engine speed becomes equal to or higher than the predetermined speed corresponding to the traveling mode during driving, the alarm means automatically performs an alarm operation, and each time, the driver is notified that the engine speed is over. Urge you to lower the engine speed. Therefore, the engine speed can be maintained in a speed range suitable for each traveling mode, and unnecessary fuel consumption can be prevented, and safe driving can be achieved.

According to a fourth aspect of the present invention, the driving mode determining means determines which of the plurality of driving modes of the vehicle corresponds to the driving mode based on the engine operating state, and the vehicle speed corresponds to the driving mode. When the speed becomes equal to or higher than the predetermined speed, the alarm means may be operated by the alarm control means. With this configuration, during driving, when the vehicle speed becomes equal to or higher than a predetermined speed set in accordance with the traveling mode, the alarm device automatically performs an alarm operation, and each time, the driver is notified that the vehicle speed is over, and the vehicle speed is increased. Urge you to lower. Therefore, the vehicle speed can be maintained at a safe speed corresponding to each traveling mode, and fuel-saving driving can be performed through safe driving.

Further, when the driving modes are distinguished into a general mode corresponding to general road driving and a high speed mode corresponding to highway driving, the general mode and the high speed mode are determined based on the vehicle speed. Should be determined. In this way, the general mode and the high-speed mode can be accurately distinguished.

In addition, the above-mentioned stop determination means, parking brake position detection means, engine forced stop means, travel mode determination means, and engine speed (vehicle speed) correspond to the travel mode. Alarm control means for outputting an alarm signal when the rotation speed becomes equal to or higher than a predetermined rotation speed (e.g., equal to or higher than a predetermined speed), and at least a vehicle speed signal, a parking brake activation signal, and an engine rotation speed signal are inputted from the vehicle side; It is preferable that the connector for outputting the engine forced stop signal and the alarm signal to the vehicle be unitized and configured. This makes it possible to easily retrofit the vehicle operation monitoring device of the present invention to an existing vehicle.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an operation monitoring device for a vehicle equipped with a diesel engine will be described below with reference to the drawings.

As shown in FIG. 2, an operation monitoring circuit 12 for monitoring the driving condition of the vehicle is built in a main body case 11 of the vehicle operation monitoring device. The main body side connector 13 (see FIG. 3) electrically connected to the connector 18 is assembled so as to be exposed outside the main body case 11. Operation monitoring circuit 1
Reference numeral 2 denotes an arithmetic unit 14 composed of a one-chip microcomputer or the like, a waveform shaping unit 15 for shaping various signals input from the vehicle side, and outputting various control signals to the vehicle side, as shown in FIG. And a power supply unit 17 to which power is supplied from a vehicle-mounted battery (not shown).

On the other hand, as shown in FIG. 2, a vehicle side connector 18 connected to the main body side connector 13 is provided on the vehicle side. The vehicle-side connector 18 is connected to a connector 19 on a key switch (not shown) side and a connector 20 on a vehicle control side via a wire harness 21, and a key switch operation signal, a battery power When an engine forcible stop condition described later is satisfied, the operation monitoring circuit 12 outputs an engine forcible stop signal (power cutoff signal) to an engine control circuit (not shown) on the vehicle side.

Further, a vehicle speed sensor 26, a tachometer 28, a warning buzzer 30 (warning means), and a parking brake switch 32 (parking brake position detecting means) are connected to the vehicle side connector 18, and a vehicle speed signal, an engine speed signal, A parking brake actuation signal is input to the operation monitoring circuit 12, and when the engine speed (vehicle speed) becomes equal to or higher than a predetermined speed (equal to or higher than a predetermined speed) set in accordance with the traveling mode, an alarm signal is output. Is output to the alarm buzzer 30. The parking brake switch 32 is turned on when a parking brake (not shown) is operated to a parking position for holding the vehicle in a stopped state.

In the case of a vehicle not provided with a vehicle speed sensor 26, a retrofit vehicle speed sensor (not shown) is attached to the vehicle so that a vehicle speed signal can be input from the retrofit vehicle speed sensor. The vehicle-side connector 18 includes:
Terminals are provided for connection to a retrofit vehicle speed sensor. The main body case 11 is housed, for example, on the back side of the meter panel near a key switch (not shown).

On the other hand, the operation unit 14 of the operation monitoring circuit 12
By executing each of the operation monitoring programs shown in FIGS. 4 to 6 stored in a built-in ROM (not shown), a vehicle speed signal, an engine speed signal, a parking brake activation signal, a key The driving condition of the vehicle is monitored based on a switch operation signal and the like. When the stopping time is prolonged, the engine is forcibly stopped. When the driving condition is against fuel-saving driving and safe driving, an alarm buzzer 3 is provided.
Activate 0 to encourage the driver to save fuel and drive safely. Hereinafter, the processing contents of each program of FIGS. 4 to 6 executed by the operation monitoring circuit 12 will be described.

[Engine Forcible Stop Control] The engine forcible stop control program shown in FIG. 4 is executed at predetermined time intervals, and functions as an engine forcible stop means described in the claims. When this program starts, first,
In step 101, it is determined whether or not the engine is rotating based on the engine speed signal. If the engine is running,
Proceeding to step 102, it is determined whether or not the vehicle is stopped based on whether or not the vehicle speed detected by the vehicle speed sensor 26 is 0. If the vehicle is not stopped, the forcible engine stop process (steps 104 to 106) described later is performed. Not performed.

On the other hand, if it is determined in step 102 that the vehicle is stopped, the process proceeds to step 103, where it is determined whether or not the parking brake has been operated to the parking position by determining whether or not the parking brake switch 32 has been turned on.
If the parking brake has not been operated to the parking position, the engine is forcibly stopped (steps 104 to 104).
Do not perform 6). The process of step 102 serves as a vehicle stop determining means in the claims.

On the other hand, when it is determined "Yes" in both steps 102 and 103, that is, when the two conditions that the parking brake is operated to the parking position while the vehicle is stopped are satisfied at the same time, Then, it is determined that the stop time is long, and the engine forcible stop processing in step 104 and thereafter is executed as follows.

First, at step 104, a timer for measuring an elapsed time after the parking brake is operated to the parking position is operated, and at next step 105, it is determined whether or not a predetermined time T has elapsed. This predetermined time T
Is preset in a range of, for example, 0 to 30 minutes according to the user's request. If the vehicle starts or the parking brake is released before the predetermined time T has elapsed, the timer is reset (step 109).

Then, when the predetermined time T has elapsed while the parking brake is being operated to the parking position while the vehicle is stopped, the engine forced stop condition is satisfied, and
Proceeding to 06, an engine forcible stop signal is output, and the electric system of the vehicle is cut off to forcibly stop the engine. On this occasion,
Electric components such as vehicle lights and air conditioners that are supplied with power from a battery are also turned off.

When the program is started while the engine is being forcibly stopped, "No" is determined in step 101, and the process proceeds to step 107, where it is determined whether the key switch 19 is operated to the off position. If “No” is determined, the engine forced stop state is continued as it is. Thereafter, when the key switch 19 is operated to the off position, "Yes" is determined in step 107,
Proceeding to step 108, the forced engine stop state is released, the engine is returned to a state in which the engine can be restarted, and the program ends. When the key switch 19 is operated to the start position (starter energizing position), the engine may be restarted by driving the starter at the same time as canceling the forced engine stop state.

Further, in this embodiment, since the predetermined time T is a fixed value, it is necessary to set the predetermined time T longer than the warm-up operation time at the start. However, the warm-up operation is completed at the start. Until the predetermined time T is set longer than usual, the predetermined time T may be shortened (or T = 0) after the warm-up is completed. With this configuration, when the parking brake is operated to the parking position while the vehicle is stopped, the engine can be forcibly stopped early and the fuel saving effect can be improved. Alternatively, at the time of starting, the engine forcible stop process may be prohibited until the warm-up operation is completed. In this case, the predetermined time T is shortened (or T = 0).
To).

[Engine Speed Warning Control] The engine speed warning control program shown in FIG. 5 is executed at predetermined time intervals, and functions as a warning control means referred to in the claims. When the program is started, first, in steps 201 to 203, based on the vehicle speed detected by the vehicle speed sensor 26, it is determined whether the current traveling mode is a general mode suitable for general road traveling or a high speed mode suitable for highway traveling. Determine. Specifically, first, in step 201, it is determined whether or not the vehicle speed detected by the vehicle speed sensor 26 is equal to or greater than 80 km / h.
To determine that the current traveling mode is the high-speed mode.

On the other hand, if the vehicle speed is less than 80 km / h,
Proceeding to step 202, it is determined whether the current traveling mode is the high-speed mode. During high-speed mode, the vehicle speed is 80 km /
Even if it falls below h, as long as it does not reach 0 km / h, the process proceeds from step 201 to step 202 to step 203 to step 204, and the high-speed mode is continued. When the vehicle speed becomes 0 km / h, "Ye
s ", and the traveling mode is switched to the general mode. This prevents the running mode from being switched to the general mode when the vehicle speed temporarily drops due to temporary traffic congestion or the like while driving on the highway.

If the vehicle is not currently in the high speed mode, if the vehicle speed is less than 80 km / h, it is determined that the vehicle is in the general mode (step 204). Steps 201 to 204 described above
And the processing of step 208 serves as a traveling mode determining means referred to in the claims.

If it is determined that the mode is the general mode, the routine proceeds to step 205, where it is determined whether or not the engine speed is equal to or higher than a predetermined speed K1. Here, the predetermined number of revolutions K1 is an upper limit number of revolutions at which economy and safety can be ensured when driving on a general road.
000 rpm (in the case of a truck diesel engine).

If it is determined that the engine speed is equal to or higher than the predetermined speed K1, it is determined that the operation is impairing the economy and safety, and the routine proceeds to step 206, where the alarm buzzer 30 is activated. , The driver is notified that the engine speed is over, and the engine speed is increased to a predetermined engine speed K1.
Encourage them to drop below. Thereafter, when the engine speed is reduced to less than the predetermined speed K1 by the driver's throttle operation and the determination at step 205 is "No",
It is determined that the vehicle is being driven at a rotational speed that can ensure economy and safety when traveling on a general road, and the routine proceeds to step 207, where the alarm operation of the alarm buzzer 30 is stopped.

On the other hand, in the case of the high-speed mode, step 2
In step 09, it is determined whether the engine speed is equal to or higher than a predetermined speed K2. Here, the predetermined number of revolutions K2 is an upper limit number of revolutions at which economy and safety can be ensured when driving on a highway.
It is preset in the range of 0 rpm (in the case of a diesel engine for trucks). If it is determined that the engine rotation speed is equal to or higher than the predetermined rotation speed K2, it is determined that an operation that impairs economy and safety is being performed, and step 210 is performed.
Then, the alarm buzzer 30 is activated to notify the driver that the engine speed is excessive, and to urge the driver to reduce the engine speed to less than the predetermined engine speed K2. Thereafter, the engine speed is reduced to less than the predetermined speed K2 by the driver's throttle operation, and when "No" is determined in step 209, the engine speed is set at a speed at which economy and safety can be ensured in highway driving. It is determined that the vehicle is being driven, and the routine proceeds to step 211, where the alarm operation of the alarm buzzer 30 is stopped.

As described above, during the high-speed mode, the high-speed mode is continued even if the vehicle speed drops to less than 80 km / h as long as it does not become 0 km / h. Therefore, even when the vehicle speed temporarily drops due to temporary traffic congestion etc. during high-speed driving,
Since the traveling mode is not switched to the general mode, it is possible to prevent the alarm buzzer 30 from operating at the predetermined rotational speed K1 of the general mode when the high-speed traveling is started again.

The vehicle speed at which the mode is switched from the general mode to the high-speed mode is not limited to 80 km / h.
/ H, 90 km / h, and other vehicle speeds. Similarly, the vehicle speed at which the high-speed mode switches to the general mode is
Not limited to 0 km / h, for example, 30 km / h, 40 km
m / h and other vehicle speeds. Further, the predetermined rotation speeds K1 and K2 for performing the alarm operation in the general mode and the high-speed mode.
Is not limited to the range of 1000 to 3500 rpm, but may be changed according to the output characteristics of the engine.

[Speed Alarm Control] In the engine speed alarm control program shown in FIG. 5 described above, the alarm buzzer 30 is operated to alarm when the engine speed exceeds a predetermined speed. In the speed alarm control program, when the vehicle speed exceeds a predetermined speed, the alarm buzzer 3
0 is set to perform an alarm operation.

The speed alarm control program shown in FIG. 6 performs the processing of steps 205 and 209 of FIG.
09a, and the other steps are the same as those in FIG. This program is also executed at predetermined time intervals, and plays a role as an alarm control means referred to in the claims.

In this program, if the current running mode is the general mode, it is determined in step 205a whether or not the vehicle speed is equal to or higher than a predetermined speed S1. Here, the predetermined speed S1 is
This is a speed near an upper limit speed or a legal speed at which economy and safety can be ensured in traveling on a general road, and is set in advance in a range of, for example, 40 to 60 km / h according to a user's request. If it is determined that the vehicle speed is equal to or higher than the predetermined speed S1, it is determined that driving that impairs economy and safety or driving that exceeds the legal speed is performed, and the process proceeds to step 206, where the alarm buzzer 30 is activated to perform an alarm operation. The driver is notified that the vehicle is over speed, and is prompted to reduce the vehicle speed to a speed lower than the predetermined speed S1. Thereafter, the vehicle speed is reduced to less than the predetermined speed S1 by the driver's throttle operation, and when it is determined to be "No" in step 205a, the speed is lower than the speed at which economy and safety can be ensured on a general road or less than the legal speed. When it is determined that the vehicle is operating at the speed, the process proceeds to step 207, and the alarm operation of the alarm buzzer 30 is stopped.

If the current running mode is the high speed mode, it is determined in step 209a whether or not the vehicle speed is equal to or higher than a predetermined speed S2. Here, the predetermined speed S2 is a speed near an upper limit speed or a legal speed at which economy and safety can be ensured in highway driving, and is set in advance in a range of, for example, 80 to 100 km / h according to a user's request. I have. If the vehicle speed is determined to be equal to or higher than the predetermined speed S2,
It is determined that driving that impairs economy and safety or driving exceeding the legal speed is performed, and the routine proceeds to step 210, where the alarm buzzer 30 is activated to alert the driver that the speed is over, and the vehicle speed is set to a predetermined value. Prompt to lower the speed below S2. Thereafter, when the vehicle speed is reduced to less than the predetermined speed S2 by the driver's throttle operation and the determination at Step 209a is "No", the vehicle is driven at a speed at which economy and safety can be ensured on a highway or at a legal speed. It is determined that the alarm has been performed, and the routine proceeds to step 211, where the alarm operation of the alarm buzzer 30 is stopped.

Also in this program, in the high-speed mode, the driving mode is not switched to the general mode unless the vehicle speed becomes 0 km / h. By switching to the general mode, it is possible to prevent the alarm buzzer 30 from operating at the predetermined speed S1 in the general mode when the high-speed running is started again.

According to the above-described embodiment, when the parking brake is operated to the parking position while the vehicle is stopped, the engine is automatically forcibly stopped after a predetermined time T has elapsed. Can be prevented. This is particularly effective for preventing idling from continuing for a long time during a nap in a vehicle or the like. Further, when the engine speed is equal to or higher than the predetermined speed K1 or the vehicle speed is equal to or higher than the predetermined speed S1 while the vehicle is traveling on a general road, the alarm buzzer 30 is activated to perform an alarm operation so that the engine rotation speed and the vehicle speed suitable for the general road can be obtained. When the engine speed is equal to or higher than the predetermined speed K2 or the vehicle speed is equal to or higher than the predetermined speed S2 while the vehicle is running on the highway, the alarm buzzer 30 is operated to perform an alarm operation. The rotation speed and the vehicle speed can be maintained, and fuel-saving driving and safe driving suitable for each driving mode can be performed.

Therefore, it is possible to constantly monitor the driving condition and carry out fuel-saving driving and safe driving reliably without spending extra time and manpower for guidance and education, etc., and to reduce exhaust gas and fuel cost. This can be realized, and wear of brakes, clutches, tires, and the like can be reduced.

In this embodiment, the parking brake is operated to the parking position while the vehicle is stopped.
When the two conditions are satisfied, the engine forced stop processing is executed, so that malfunction of the engine forced stop system can be prevented, and reliability and safety can be improved.

If the engine is forcibly stopped during a short stoppage time, the disadvantages of exhausting harmful gas during restarting are greater than the exhaust gas reduction effect of stopping the engine. The engine must be restarted every time it is stopped, which impairs drivability.

In this regard, in this embodiment, the engine is stopped only when the parking brake is operated while the vehicle is stopped, that is, when it can be determined that the stop time is prolonged. It is possible to surely increase the demerit due to the emission of harmful gas at the time of starting, and it is not troublesome to restart the engine every time the vehicle stops for a short time, and the drivability is not impaired.

Further, in the present embodiment, the general mode and the high-speed mode are determined based on the vehicle speed.
The general mode and the high-speed mode can be accurately distinguished. However, the driving mode may be determined based on, for example, the throttle opening or the engine speed. In addition to the general mode and the high-speed mode, for example, a city area mode, a mountain road mode, or the like may be determined.

In this embodiment, the operation monitoring circuit 12 is built in the main body case 11 and the operation monitoring circuit 1
Since the main body side connector 13 for electrically connecting the vehicle body 2 to the vehicle side is assembled so as to be exposed to the outside of the main body case 11, the unit is compactly unitized. Therefore, the vehicle operation monitoring device of the present invention is significantly modified to an existing vehicle. It can be easily retrofitted without performing Of course, it goes without saying that the vehicle operation monitoring device of the present invention may be assembled on a vehicle production line.

In the above embodiment, the engine forced stop control, the engine speed alarm control, and the speed alarm control are all performed. However, one or two of these may be performed. . Further, the warning means is not limited to a warning by a buzzer sound, but may be a warning by sound, a chime, or the like, or a warning by lighting or blinking of a warning lamp. In the above embodiment, the present invention is applied to a vehicle equipped with a diesel engine, but may be applied to a vehicle equipped with another type of engine such as a gasoline engine.

[0047]

As is apparent from the above description, according to the vehicle operation monitoring apparatus of the first aspect of the present invention, when the parking brake is operated to the parking position while the vehicle is stopped, the engine is automatically forcibly stopped. Therefore, it is possible to constantly monitor the operation state and perform the fuel-saving operation without extra time and manpower, thereby realizing reduction of exhaust gas and reduction of fuel cost. In addition, since the stop of the vehicle and the operation of the parking brake are two conditions for forcibly stopping the engine, malfunction can be prevented, and the engine is prevented from being forcibly stopped every time the vehicle is stopped for a short time, thereby reducing the exhaust gas. Can be assured, and drivability is not impaired.

Furthermore, in the second aspect, when the key switch is operated to the OFF position, the engine forced stop state is released to enable the engine to be restarted, so that the engine forced stop state is easily released. The engine can be restarted.

On the other hand, the present invention is characterized in that the present running mode is determined, and the warning means is automatically activated when the engine speed exceeds a predetermined speed corresponding to the current running mode. The user can keep the engine speed in the engine speed range suitable for the current traveling mode, and can perform fuel-saving driving and safe driving.

According to the present invention, when the vehicle speed becomes equal to or higher than a predetermined speed corresponding to the current traveling mode, the warning means automatically activates a warning, so that the driver can adjust the vehicle speed to the current traveling mode. Can be kept at safe speed,
Fuel-saving driving can be performed through safe driving.

Further, since the general mode and the high-speed mode are determined based on the vehicle speed, the general mode and the high-speed mode can be accurately determined.

Further, since the above-described functions are combined into a unit to form a unit, the vehicle operation monitoring device of the present invention can be easily retrofitted to an existing vehicle.
