Embodiment 1

[0052] Such as figure 1 As shown, the embodiments of the present invention provide a method for controlling the driving state of the vehicle, including:

[0053] Step 11, obtain the status information of the keyless start system PEPS;

[0054] Step 12, according to the status information of the PEPS, obtain the gear position information of the current vehicle;

[0055] Step 13. Obtain current vehicle speed information according to the gear position information;

[0056] Step 14. Control the driving state of the vehicle according to the state information of the PEPS, the gear position information and the vehicle speed information of the vehicle.

[0057] In this embodiment, the vehicle controller receives the vehicle gear position information and vehicle speed information sent by the drive motor controller, and combines the status of the PEPS system to determine whether the current vehicle is coasting in neutral or with the engine off. If the PEPS system is always ON, the dr...

Embodiment 2

[0089] Such as Figure 5 As shown, the embodiment of the present invention also provides a control device for the driving state of the vehicle, including:

[0090] The first obtaining module 51 is used to obtain the status information of the keyless start system PEPS;

[0091] The second obtaining module 52 is used to obtain the gear position information of the current vehicle according to the state information of the PEPS;

[0092] The third acquiring module 53 is configured to acquire current vehicle speed information according to the gear position information;

[0093] The control module 54 is configured to control the driving state of the vehicle according to the state information of the PEPS, the gear position information and the vehicle speed information of the vehicle.

[0094] In this embodiment, the vehicle controller receives the vehicle gear position information and vehicle speed information sent by the drive motor controller, and combines the status of the PEPS s...

Abstract

The invention discloses a method and a device for controlling vehicle driving states, and a vehicle. The method for controlling vehicle driving states comprises: obtaining status information of a keyless start system PEPS; according to the status information of the PEPS, obtaining gears information of a current vehicle; according to the gears information, obtaining current vehicle speed information; according to the status information of the PEPS, the gears information of the vehicle, and the vehicle speed information, controlling a vehicle driving state. Through determining PEPS status, the vehicle current gears information, and the vehicle speed information, the method and the device prompt a driver in time when the vehicle is in neutral position coasting or coasts with engine off. The method and the device effectively reduce occurrence of accidents, and make a driver overcome bad habits of neutral position coasting and coasting with engine off.

Description

technical field [0001] The invention relates to the field of automobile driving safety, in particular to a method and device for controlling the driving state of a vehicle and an automobile. Background technique [0002] Now drivers driving fuel vehicles or pure electric vehicles widely use the keyless start system PEPS and electronic parking system, and many drivers have bad habits of coasting in neutral or stalling when going downhill or decelerating. Vehicles coasting in neutral without the help of engine braking will make the braking effect of the car, especially the overloaded vehicle, not good, and will cause the vehicle to lose balance and slide left and right, which may cause accidents due to the driver's inability to control the car; the vehicle will slide with the engine off At this time, the power steering will stop working, the steering wheel will be locked, and the air compressor will stop working, which will cause insufficient brake air in the air reservoir. Wh...
