Abstract

The invention provides a vehicle control method and device. The vehicle control method comprises the steps that first vehicle information is collected and obtained, wherein the first vehicle information comprises the rotating direction of a motor; whether a vehicle slides or not is judged according to the rotating direction of the motor; if the judging result is that the vehicle slides, the vehicle siding degree is determined according to the first vehicle information; compensation traction force corresponding to the vehicle sliding degree is provided for the vehicle according to the vehicle sliding degree; second vehicle information is collected and obtained, wherein the second information comprises current travelling parameters of the vehicle; and according to the current travelling parameters of the vehicle, whether the condition of canceling the compensation traction force is met or not is judged, and if yes, the compensation traction force is canceled. According to the vehicle control method and device, whether the vehicle slides or not can be automatically judged, and the corresponding compensation traction force is provided for the vehicle according to the vehicle sliding degree, the traction force compensated for the vehicle is canceled when the vehicle meet the condition of canceling the compensation traction force, and the problem that in the prior art, the traction force cannot be compensated for the vehicle according to the vehicle sliding condition is solved.

Description

technical field

[0001] The invention relates to vehicle control technology, in particular to a vehicle control method and device, and belongs to the technical field of vehicle control. Background technique

[0002] In recent years, rail transit has been widely used in the urban transportation systems of the whole country and even the world, and the operation safety of rail transit has attracted more and more people's attention. However, the driving conditions of rail transit are complex, and the operating route contains various ramps, and vehicles need to start and stop frequently on the ramps. In order to ensure that the vehicles do not roll when starting on the ramps, there are currently two ramp start control methods. used in rail transit.

[0003] The first method is to increase the starting traction of the vehicle and cooperate with the braking of the vehicle. Collect the operating route information of the vehicle in advance, obtain the largest ramp information in the...

Embodiment Construction

[0027] figure 1 A flow chart of a vehicle control method shown in an exemplary embodiment of the present invention, including:

[0028] Step 101, collect and acquire the first information of the vehicle, the first information of the vehicle includes: motor steering.

[0029] Step 102, judging whether the vehicle is slipping according to the steering of the motor.

[0030] Taking a rail vehicle as an example, when the vehicle is running normally, the traction force is provided by the motor of the vehicle, and the traction force is transmitted to the wheels through the gearbox to drive the vehicle to run. When the vehicle slides, the vehicle is subjected to the gravity component parallel to the ramp, causing the vehicle to slide down. When the vehicle slides, the wheels rotate and are transmitted to the motor through the gearbox to drive the motor to rotate. The steering of the motor is different when the vehicle is running forward normally and when the vehicle is slipping, an...
