Abstract

The invention provides a slope starting anti-car-sliding control system and method thereof. The control system comprises a signal input unit, a whole car controller and a motor controller, wherein the signal input unit comprises a gear device, a brake pedal and an accelerator pedal; the gear device, the brake pedal and the accelerator pedal are respectively connected with the whole car controller, and are used for inputting the driving motor rotating speed, the accelerator pedal or brake pedal opening degree and the gear signals of a car into the whole car controller; the whole car controller is connected with the motor controller; the whole car controller feeds back instructions corresponding to slope starting anti-sliding mode starting or ending to the motor controller according to parameters of the signal input unit. On the basis of not changing the operation of a driver, the backward sliding distance of the car is enabled to be in a safe distance, and the safety of the car is improved.

Description

technical field [0001] The invention relates to a driving control strategy of a pure electric vehicle, in particular to a slope-start anti-rolling control system and a method thereof. Background technique [0002] For pure electric vehicles, when the vehicle starts on a slope, without using the handbrake, when the right foot leaves the brake pedal and then steps on the accelerator pedal, the vehicle will slide backwards to varying degrees, which is likely to cause ACCIDENT. The anti-rolling function of the slope is to solve the problem of the pure electric vehicle rolling backward when starting on the slope. When the vehicle is found to be rolling backward, the torque can be quickly adjusted by the motor to stabilize the vehicle in a static state and ensure the distance of the vehicle rolling backward. Control within a safe distance. [0003] Patent (103754222A) discloses a method for realizing the auxiliary control function of electric vehicles on hills, including two ste...
