Anti-slope-sliding control method and device and vehicle

Abstract

The invention provides an anti-slope-sliding control method and device and a vehicle. The method comprises the steps of obtaining the current inclination angle of the vehicle; under the condition that it is determined that the vehicle is in the anti-slope-slipping working condition according to the inclination angle, if it is determined that the vehicle is not in the ESP stable slope state currently, obtaining the brake pedal opening degree of the vehicle; determining the current slope stabilizing torque according to the inclination angle and the opening degree of the brake pedal; and controlling a driving motor in the vehicle to output power according to the current slope stabilizing torque. Under the condition that it is determined that the vehicle is in the anti-slope-slipping working condition, the current slope stabilizing torque can be adjusted according to the inclination angle and the brake pedal opening degree, even if the brake pedal is not stepped on, a drive motor in the vehicle can be controlled to conduct power output according to the current slope stabilizing torque, slope slipping of the vehicle can be effectively prevented, and safety performance of a vehicle is enhanced.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, in particular, to a slope prevention control method, device and vehicle. Background technique [0002] The current anti-slope technology usually includes ESP (Electronic Stability Program, vehicle body electronic stability system) slope stabilization technology and VCU (Vehicle control unit, vehicle controller) based slope stabilization control. The support of hardware devices means that the vehicle must be equipped with an ESP function device. Compared with the VCU-based slope stabilization control, the ESP slope stabilization technology requires a higher investment cost, which is not conducive to reducing the production cost of the vehicle; while the current VCU-based stabilization control Slope control usually only prevents slopes when the brake pedal is released. It cannot prevent slopes when the brake pedal is not stepped on, and cannot effectively avoid unsafe accidents. It is no...
