FIG. 1 is a flowchart for explaining a method of controlling a vehicle operation according to an embodiment of the present invention. FIG. 2 is a schematic diagram for explaining a control system for implementing the vehicle operation control method shown in FIG. 1 to be.

Referring to FIGS. 1 and 2, a method of controlling the operation of a vehicle according to an embodiment of the present invention can be used to prevent a traffic accident that may occur when the vehicle starts. Particularly, in case of starting a vehicle after stopping the vehicle according to a traffic signal in the case of a road with a traffic light such as an intersection, when starting the vehicle after a temporary stop on the road, The operation control method of the invention can be used.

According to an embodiment of the present invention, there is provided a method of controlling a vehicle, including: monitoring a front situation of the vehicle for departure of a vehicle (S100); determining whether the vehicle is allowed to depart according to a front situation of the vehicle (S110), and controlling the operation of the braking device of the vehicle according to the determination (S120).

The monitoring of the forward situation of the vehicle can be performed through the front camera 110 and / or the radar sensor 112 installed in the vehicle. For example, when the vehicle is waiting for a signal in a place where there is a traffic light such as an intersection, the front camera 110 may monitor a traffic signal in front of the vehicle. Particularly, a blinking state of a traffic signal corresponding to a lane where the vehicle is currently located, for example, a left turn or a straight lane, etc., can be monitored.

On the other hand, the front camera 110 can check which lane the current vehicle is positioned in the straight line, the left turn, and the right turn through an indicator such as an arrow displayed on the road surface before the vehicle arrives at the intersection.

In addition, whether a pedestrian or an obstacle exists in front of the vehicle can be monitored by using the front camera 110 and / or the radar sensor 112 installed in the vehicle. For example, it is possible to monitor whether there is an obstacle to the departure of the vehicle, such as a pedestrian before departure of the vehicle or a sudden interruption of the vehicle.

According to an embodiment of the present invention, a video signal obtained by the front camera 110 and a sensing signal generated from the radar sensor 112 are transmitted to a vehicle body posture control apparatus 100 through an internal communication network, Stability Control), and the video signal can be analyzed through the processor of the body posture control apparatus 100. [ In particular, the vehicle body posture control apparatus 100 can determine whether or not the vehicle is allowed to depart according to the video signal and / or the sensing signal, thereby controlling the driving of the vehicle.

According to another embodiment of the present invention, the video signal may be transmitted to a separate image processing apparatus (not shown), and the blinking state of a traffic light or the presence or absence of an obstacle may be determined in the image processing apparatus have. In this case, the result determined by the image processing apparatus may be provided to the vehicle body posture control apparatus 100.

Referring again to FIG. 1, the braking device 120 of the vehicle can be appropriately controlled depending on whether or not the start of the vehicle is allowed. For example, when the vehicle is allowed to start normally according to lighting of a traffic light, the driver can start the vehicle by operating the accelerator 130 such as an accelerator as usual.

However, if the vehicle is not allowed to start, for example, the driver may predict the vehicle to be driven in a state where the straight-ahead signal, that is, the green light, etc., A case may arise. In this case, the vehicle body posture control device 100 can be configured to operate the braking device 120 of the vehicle to suppress the start of the vehicle. Accordingly, an accident that may occur when the driver operates the accelerator 130 to forcibly start the vehicle in a state in which the vehicle is not allowed to start can be prevented in advance.

As another example, in the case where the vehicle is located in the left-turn lane, even if the driver unconsciously starts or the left-turn signal lamp does not light up as the straight ahead vehicle departs, The unauthorized start of the vehicle can be suppressed.

As another example, the presence of an obstacle in front of the vehicle can be monitored through the front camera 110 and the radar sensor 112 even when the vehicle starts from a state where the vehicle is temporarily stopped on the roadside or parked in a parking lot , Whereby the start of the vehicle can be controlled. Particularly, even when a driver suddenly jumps a pedestrian or interrupts another vehicle suddenly when the accelerator 130 is operated, the braking device 120 of the vehicle can be operated faster than the driver, so that an accident Can be greatly reduced.

According to an embodiment of the present invention, the vehicle body posture control apparatus 100 may be connected to the power train control apparatus 140, and when the vehicle is not allowed to start as described above, It is possible to control the engine operation of the vehicle such that the number of engine revolutions of the vehicle is not increased through the power train control device 140 and to control the engine operation of the vehicle such that the driving force from the vehicle engine is not transmitted to the driving wheels, The operation of the delivery device can be controlled.

In addition, when the start of the vehicle is permitted, the braking device 120 of the vehicle can be deactivated to allow a normal start. Particularly, when the start of the vehicle is suppressed by the braking device 120, the driver can release the operation of the braking device 120 by manually inputting an operation release signal of the braking device 120. [ As an example, the operation release signal of the braking device 120 may be inputted by the operation of the brake pedal of the vehicle. That is, when the starting of the vehicle is automatically suppressed by the braking device 120, the driver temporarily presses the brake pedal, and the vehicle body posture control device 100 senses the operation of the brake pedal, It is possible to cancel the operation state of the battery 120.

As another example, the vehicle may be provided with a switch (not shown) or the like for releasing the operating state of the braking device 120, and the driver may control the braking device 120 120 may be released.

According to an embodiment of the present invention, the vehicle body posture control apparatus 100 may be connected to a display device 150 and an acoustic device 152 installed in a vehicle. When the start of the vehicle is suppressed as described above, A warning message may be provided to the driver through the display device 150 and the sound device 152. For example, the warning lamp may be turned on or a warning sound may be generated, and the warning message may be stopped when an operation release signal of the braking device 120 is input by the driver.

Meanwhile, although not shown, the method of controlling a vehicle according to an embodiment of the present invention may further include releasing an operation control of the braking device 120 according to a driver's intention. For example, when the blinking state of the turn signal lamp of the vehicle is changed by the driver, the operation of the braking device 120 may be detected by the vehicle body posture control device 100 and released.

For example, when the driver wants to change lanes, the operation control state of the braking device 120 can be released by changing the blinking state of the turn signal lamp, that is, by turning on or off the turn signal lamp. You can proceed as usual.

Further, although not shown, the step of acquiring information on the forward situation of the vehicle when the vehicle is stopped and the step of storing the information may be further performed. More specifically, information regarding the forward situation at the time of stopping the vehicle, for example, a lane in which the present vehicle is located, a blinking state of a traffic signal, an obstacle in front of the vehicle, and the like are acquired by the front camera 110 and the radar sensor 112 And the information can be stored in the body posture control device 100. [ The information stored as described above can be used as basic information at the start of the vehicle and can be compared with information obtained at the start of the vehicle. Therefore, the running control at the start of the vehicle can be performed more easily.

According to the embodiments of the present invention as described above, when the start of the vehicle is not allowed, for example, when the vehicle should not start due to a traffic signal, a pedestrian, an obstacle or the like, the driver operates the accelerator 130 The braking device 120 of the vehicle can be operated automatically. Therefore, it is possible to prevent a traffic accident from occurring due to an unacceptable departure of the vehicle.

Particularly, even when the accelerator 130 is unconsciously operated by the elderly or the driver whose movement reaction is relatively slow, the operation of the braking device 120 of the vehicle, the engine, the power transmission device and the like can be automatically controlled, Traffic accidents caused by vehicle departure can be greatly reduced.
