Description

  The present invention relates to a vehicle-mounted device that notifies an abnormality in a vehicle interior situation.

  Conventionally, when an occupant remains in a parked vehicle and the temperature inside the vehicle exceeds a certain temperature, an in-vehicle system that notifies the outside of the vehicle and cools the interior of the vehicle has been proposed (for example, patents) Reference 1).

JP2012-153232A

  However, in the system described in Patent Document 1, since notification to the outside of the vehicle and cooling of the passenger compartment are executed regardless of the intention of the passenger in the vehicle, these processes may not be necessary depending on the passenger. For example, it is effective for children left in the car, but if it is an adult passenger who remains in the car for a break, it is possible to adjust the car temperature etc. by judging the situation inside the car, The above processing executed by the system is not necessary.

  Moreover, since the said operation | movement is performed without considering an emergency degree, there existed a subject that the electric power of a vehicle-mounted battery was consumed wastefully. For example, if the current in-vehicle temperature exceeds a reference value but the in-vehicle temperature tends to decrease without cooling the interior of the vehicle, the degree of urgency is low. In this case, the vehicle interior temperature is likely to be lower than the reference value without cooling the vehicle interior, and the power of the in-vehicle battery should not be consumed by cooling the vehicle interior.

  This invention solves the said subject, and aims at obtaining the vehicle-mounted apparatus which can perform appropriately the process with respect to the abnormality of the vehicle interior condition of the parked vehicle.

The in-vehicle device according to the present invention includes an in-vehicle situation determination unit, a warning control unit, a response determination unit, a rank determination unit, a processing content determination unit, and a device control unit.
The in-vehicle situation determination unit determines whether the in-vehicle situation is abnormal and an occupant is present in the vehicle based on the detection information of the in-vehicle situation of the parked vehicle. The warning control unit warns the passengers in the vehicle when the in-vehicle state determination unit determines that the in-vehicle state is abnormal and the passenger is present in the vehicle. The response determination unit determines whether a response to the warning has been received from a passenger in the vehicle. A rank determination part determines the rank which shows the emergency degree of abnormality of a vehicle interior condition, when it determines with the response determination part not receiving the response. The process content determination unit determines the content of the process for the abnormality in the vehicle interior according to the rank determined by the rank determination unit. The device control unit controls the device mounted on the vehicle and performs processing of the content determined by the processing content determination unit.

  According to the present invention, when there is no response to a warning of an abnormality in the in-vehicle situation, the processing for this abnormality is executed, so that the processing can be performed for a passenger such as a child who does not have the ability to make a response. Moreover, since the process according to the urgency degree of the abnormality of the in-vehicle situation is performed, it is possible to perform an appropriate process without wasteful power consumption.

It is a block diagram which shows the structure of the vehicle-mounted apparatus which concerns on Embodiment 1 of this invention. FIG. 3 is a block diagram illustrating a configuration of a control unit in the first embodiment. 4 is a flowchart showing an operation of the in-vehicle device according to the first embodiment. 6 is a flowchart showing another operation of the in-vehicle device according to the first embodiment.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of the in-vehicle device 1 according to Embodiment 1, and shows the hardware configuration of the in-vehicle device 1. FIG. 2 is a block diagram illustrating a configuration of the control unit 2, and illustrates a functional configuration of the control unit 2. The in-vehicle device 1 is a device including the control unit 2 and is realized as, for example, a car navigation device. The in-vehicle device 1 is connected to a GPS (Global Positioning System) receiving device 3, a memory 4, a sensor group 5, an audio output device 6, an operation device 7, a camera 8, an out-of-vehicle notification device group 9, and an air conditioner 10.

The control unit 2 is realized as, for example, a CPU (Central Processing Unit), and controls operations of the in-vehicle device 1 and the above-described devices connected thereto.
Moreover, the control part 2 is provided with the vehicle interior condition determination part 2a, the warning control part 2b, the response determination part 2c, the rank determination part 2d, the process content determination part 2e, and the apparatus control part 2f as the function structure.

  The in-vehicle situation determination unit 2a determines whether the in-vehicle situation is abnormal and an occupant is present in the vehicle based on the detection information of the in-vehicle situation from the sensor group 5. For example, when the vehicle interior temperature is equal to or higher than a reference value, it is determined that the vehicle interior condition is abnormal. Moreover, the warning control part 2b warns the passenger | crew in a vehicle, when the vehicle interior condition determination part 2a determines with the vehicle interior condition being abnormal. For example, the voice output device 6 is used to issue a voice warning such as “the temperature inside the vehicle is over XX degrees. There is a possibility of heat stroke, so please adjust the temperature.”

  The response determination unit 2c determines whether a response to the warning is received from the occupant using the operation device 7. For example, when the occupant remaining in the vehicle responds, it is determined that the occupant can determine the in-vehicle situation, and the in-vehicle device 1 does not automatically process the abnormality in the in-vehicle state. On the other hand, if there is no response within a predetermined time after the warning is given, it is determined that the response has not been accepted. In this case, it is determined that the occupant remaining in the vehicle is a child who cannot determine the in-vehicle situation.

The rank determination unit 2d determines a rank indicating the urgent degree of abnormality of the in-vehicle situation when the response determination unit 2c determines that the response has not been accepted.
For example, the rank determination unit 2d refers to the table data in which each rank is set in association with information such as whether the vehicle position and the stopping place are indoors or outdoors, season, time zone, weather, etc., and matches the current situation. Determine the rank.

In this table data, when the in-vehicle temperature is estimated to increase or the high temperature tends to continue from each information, a high degree of urgency, that is, a high rank is set.
If the vehicle is parked outdoors on the south side, the season is summer, the time zone is daytime, and the weather is clear, the temperature inside the vehicle above the reference value tends to rise or continue. The highest S rank is set. On the contrary, when it is estimated that the in-vehicle temperature tends to decrease, the degree of urgency is low and a low rank is set.
In addition, when the in-vehicle temperature greatly exceeds the reference value, for example, when the difference obtained by subtracting the reference value from the in-vehicle temperature is equal to or higher than a predetermined threshold value, a high rank may be set.

The processing content determination unit 2e determines the content of processing for an abnormality in the in-vehicle situation according to the rank determined by the rank determination unit 2d. In addition, the device control unit 2f controls the device mounted on the vehicle and performs processing of the content determined by the processing content determination unit 2e.
For example, the processing content determination unit 2e may adjust the in-vehicle temperature, notify the abnormality to the outside device, notify the abnormality around the vehicle, unlock the vehicle door, open the vehicle window, and a combination of these conditions. Determine the content of processing for abnormalities. Thereby, an appropriate process can be performed with respect to abnormality of the in-vehicle situation.

Note that the notification of abnormality to the outside device is to notify the outside device registered in advance of the abnormality. Here, a driver's smart phone, a police station server device, etc. are mentioned as the notification-destination device registered in advance.
In addition, in the notification of abnormality around the vehicle, notification is performed visually or audibly.
For example, as a visual notification, it is conceivable to blink a hazard lamp. For audible notifications, horns can be heard.

  The GPS receiver 3 analyzes the current position and current time of the vehicle from the GPS information received from the GPS satellite. In addition, the GPS information can be obtained for a time zone such as season, night or noon. The memory 4 is a memory in which a map database is stored. For example, the control unit 2 can grasp whether the vehicle is stopped indoors or outdoors based on the current position of the vehicle analyzed by the GPS receiver 3 and the map data. .

  The sensor group 5 includes a plurality of sensors that respectively detect temperature, illuminance, humidity, and presence / absence of an occupant indicating an in-vehicle situation. For example, a temperature sensor that detects the temperature in the vehicle, an illuminance sensor that detects the illuminance in the vehicle, a humidity sensor that detects the humidity in the vehicle, and a moving body sensor that detects the presence or absence of a living body in the vehicle. The sensor group 5 performs detection in response to a control signal from the in-vehicle situation determination unit 2a.

The audio output device 6 is a speaker arranged in the passenger compartment, and outputs, for example, guidance sound of a car navigation device, an audio warning output from the warning control unit 2b, and the like.
The operating device 7 is a device serving as a user interface that responds to a warning from the warning control unit 2b, and may use a touch panel, a hard key, or the like, but may accept a response by voice recognition using a microphone.

The camera 8 captures an image around the vehicle (such as a surround view image). The processing content determination unit 2e analyzes the captured image input from the camera 8 and determines the presence or absence of a person around the vehicle.
The vehicle outside notification device group 9 is a device group that notifies the vehicle outside device and abnormality around the vehicle, and includes, for example, a communication module that communicates with the vehicle outside device, a hazard lamp lighting device, a horn activation device, and the like. The The air conditioner 10 is an air conditioner mounted on a vehicle and performs air conditioning of the passenger compartment.

Next, the operation will be described.
FIG. 3 is a flowchart showing the operation of the in-vehicle device 1 and shows a series of processes related to an abnormality notification of the in-vehicle situation.
First, the in-vehicle situation determination unit 2a checks whether or not a certain time has elapsed after the vehicle engine is turned off (step ST1). Here, the fixed time indicates the time from when the vehicle is stopped and the driver gets off and the vehicle door is locked, and is, for example, about 5 to 10 minutes.
If a certain time has not elapsed since the engine was turned off (step ST1; NO), the process of step ST1 is repeated.

When a certain time has elapsed since the engine was turned off (step ST1; YES), the in-vehicle state determination unit 2a instructs the sensor group 5 to detect the in-vehicle temperature. The temperature sensor of the sensor group 5 detects the in-vehicle temperature in accordance with an instruction from the in-vehicle state determination unit 2a.
Next, the vehicle interior state determination unit 2a checks whether the vehicle interior temperature is equal to or higher than a reference value based on the detection information of the temperature sensor (step ST2). Here, when the in-vehicle temperature is lower than the reference value (step ST2; NO), the process of step ST2 is repeated.

On the other hand, when the vehicle interior temperature is equal to or higher than the reference value (step ST2; YES), the vehicle interior situation determination unit 2a determines that the vehicle interior situation is abnormal and detects the presence or absence of a living body in the vehicle with respect to the sensor group 5. To instruct. The moving body sensor of the sensor group 5 detects the presence or absence of a living body in the vehicle according to an instruction from the in-vehicle situation determination unit 2a.
Next, the in-vehicle situation determination unit 2a checks whether or not a living body exists in the vehicle based on the detection information of the moving body sensor (step ST3). If there is no living body in the vehicle (step ST3; NO), the process is terminated.

  When there is a living body in the vehicle (step ST3; YES), the vehicle interior state determination unit 2a determines that there is an occupant other than the driver in the vehicle and instructs the warning control unit 2b to warn. For example, the warning control unit 2b causes the audio output device 6 to output a warning sound in accordance with an instruction from the in-vehicle situation determination unit 2a (step ST4).

The response determination unit 2c determines whether or not there is a response to the warning before a predetermined time has elapsed after the warning sound is output by the warning control unit 2b (step ST5).
At this time, if there is a response to the warning from the occupant using the operating device 7 (step ST5; YES), the process is terminated.
If a response to the warning is not received from the occupant even after a certain time has elapsed (step ST5; NO), the response determination unit 2c determines that the occupant in the vehicle is a child and ranks the in-vehicle situation The rank determination unit 2d is instructed to

The rank determination unit 2d refers to the table data in which each rank is set in association with information such as whether the vehicle position and the stopping place are indoors or outdoors, the season, the time zone, the weather, etc., and determines the rank that matches the current situation. Determination is made (step ST6). For example, the rank determination unit 2d acquires the vehicle position and the current time as the analysis result of the GPS receiver 3, and specifies the season and the time zone from the current time.
The rank determination unit 2d determines whether the stop location is indoor or outdoor from the facility information of the map data read from the memory 4 and the vehicle position. Furthermore, the rank determination unit 2d determines the weather around the vehicle from the detection information of the humidity sensor of the sensor group 5.

  Next, the processing content determination unit 2e checks whether or not the rank of the in-vehicle situation is a rank that should be processed immediately (step ST7). Here, it is confirmed whether or not the rank is higher than a predetermined rank. If the rank is not to be processed immediately (step ST7; NO), the processing content determination unit 2e determines that the abnormality in the vehicle interior tends to end and ends the processing.

When the rank is to be processed immediately (step ST7; YES), the processing content determination unit 2e determines the adjustment of the in-vehicle temperature as the processing content for the abnormality in the in-vehicle situation. Thereby, the device control unit 2f controls the air conditioner 10 to adjust the vehicle interior temperature (step ST8).
Subsequently, the processing content determination unit 2e analyzes the captured image input from the camera 8 and determines the presence or absence of a person around the vehicle (step ST9).

When it is determined that there is no person around the vehicle (step ST9; NO), the process is terminated in a state where the adjustment of the in-vehicle temperature by the device control unit 2f is continued.
When it is determined that there is a person around the vehicle (step ST9; YES), the processing content determination unit 2e excludes the adjustment of the in-vehicle temperature from the content to be processed, and the content of the abnormality notification to the vehicle periphery is to be processed. decide. Thereby, the apparatus control part 2f stops adjustment of vehicle interior temperature, and operates a horn or a hazard lamp (step ST10).

  In FIG. 3, if the presence of a person in the vicinity of the vehicle is detected after adjusting the temperature inside the vehicle, if the rank of the in-vehicle situation is a rank to be processed immediately, the adjustment of the inside temperature is stopped and The case of notifying an abnormality is shown. As a result, the power consumption of the in-vehicle battery can be suppressed while promptly executing the process for the abnormality in the vehicle interior.

The processing content for the abnormality in the in-vehicle situation may be determined in consideration of the in-vehicle battery remaining amount.
FIG. 4 is a flowchart showing the operation of determining the processing content for the abnormality in the in-vehicle situation in consideration of the in-vehicle battery remaining amount, and is a series of processing replacing the portion A in FIG.
For example, as a sensor constituting the sensor group 5, it is assumed that there is a sensor that detects the remaining amount of the in-vehicle battery. The process content determination unit 2e determines whether or not the in-vehicle battery remaining amount is less than a predetermined threshold based on the detection information of the in-vehicle battery remaining amount (step ST9a).
Note that this threshold value indicates the remaining amount of power at which the time during which the operation of the in-vehicle device can be continued is less than a certain time.

When the in-vehicle battery remaining amount is less than the threshold (step ST9a; YES), the processing content determination unit 2e analyzes the captured image input from the camera 8 and determines the presence or absence of a person around the vehicle (step ST10a).
When it is determined that there is a person around the vehicle (step ST10a; YES), the processing content determination unit 2e excludes the adjustment of the in-vehicle temperature from the content to be processed, notifies the abnormality around the vehicle, and unlocks the vehicle door The opening of the vehicle window is determined as the content to be processed.
Thereby, the device control unit 2f stops the adjustment of the in-vehicle temperature, operates the horn or the hazard lamp, opens the vehicle window, and unlocks the vehicle door (step ST11a).

When it is determined that there is no person around the vehicle (step ST10a; NO), the processing content determination unit 2e excludes the adjustment of the in-vehicle temperature and the notification of abnormality to the vehicle periphery from the content to be processed, The opening of the lock and the vehicle window is determined as the content to be processed.
Thereby, the device control unit 2f stops the adjustment of the in-vehicle temperature, does not operate the horn or the hazard lamp, opens the vehicle window, and unlocks the vehicle door (step ST12a).
By doing in this way, the process with respect to abnormality of a vehicle interior condition can be performed, suppressing the power consumption of a vehicle-mounted battery to the minimum.

On the other hand, when the in-vehicle battery remaining amount is equal to or greater than the threshold (step ST9a; NO), the processing content determination unit 2e analyzes the captured image input from the camera 8 and determines the presence or absence of a person around the vehicle (step ST13a). ).
Here, when it is determined that there are people around the vehicle (step ST13a; YES), the processing content determination unit 2e determines the adjustment of the in-vehicle temperature and the notification of abnormality to the vehicle periphery as the content to be processed. Thereby, the equipment control unit 2f operates the horn or the hazard lamp while continuing the adjustment of the in-vehicle temperature (step ST14a).

When it is determined that there is no person around the vehicle (step ST13a; NO), the processing content determination unit 2e determines only the adjustment of the in-vehicle temperature as the content to be processed.
Thereby, the apparatus control part 2f continues adjustment of vehicle interior temperature, and does not operate a horn or a hazard lamp (step ST15a).

  In the above description, the case where it is determined that the vehicle interior condition is abnormal when the vehicle interior temperature rises above the reference value is shown. However, when the vehicle interior temperature is less than another reference value, the vehicle interior condition is abnormal. It may be determined that Further, the present invention is not limited to an abnormality in the vehicle interior temperature.
