Problems solved by technology

[0003] For existing electric vehicles, when the driver releases the accelerator pedal of the vehicle when the vehicle is going uphill, the vehicle will be affected by two kinds of resistance, regenerative braking and slope resistance, causing the vehicle to decelerate too quickly phenomenon, which is not conducive to the driver's timely response and control of the vehicle, thus bringing safety hazards to the vehicle

Abstract

The invention relates to the technical field of automobiles, and discloses a vehicle torque compensation method, device, vehicle and storage medium. The method includes: calculating the required torque of the vehicle in real time; identifying the current driving state of the vehicle and the current state of the accelerator pedal of the vehicle; When it is recognized that the current driving state of the vehicle is an uphill state, and the current state of the accelerator pedal is released, calculate the compensation torque of the vehicle; calculate the target torque of the vehicle according to the demand torque and compensation torque, and control the vehicle's torque according to the target torque motor. The invention realizes that when the vehicle goes uphill and the driver releases the accelerator pedal, the compensation torque is applied to the vehicle in time to reduce the rate of vehicle speed drop, thereby prolonging the driver's reaction time to ensure that the driver has sufficient time Control the vehicle, thus ensuring the safety of the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle torque compensation method, device, automobile and storage medium. Background technique [0002] At present, with the increasing energy crisis and environmental pollution, electric vehicles have gradually entered daily life due to their relatively small impact on the environment; therefore, dedicating to the development of electric vehicles is bound to be the long-term development trend of the automotive industry. Among them, the performance of the electric vehicle control system will affect the performance index of the electric vehicle, and the quality of the drive control has a direct impact on the performance of the electric vehicle. [0003] For existing electric vehicles, when the driver releases the accelerator pedal of the vehicle when the vehicle is going uphill, the vehicle will be affected by two kinds of resistance, regenerative braking and slope resistan...
