Abstract

The invention provides a torque control method and device and a vehicle. The method comprises the steps that when the vehicle is in a single-pedal mode, the opening degree of an accelerator pedal and the current vehicle speed of the vehicle are collected; vehicle speed deviation is determined according to the accelerator pedal opening degree and the current vehicle speed; and determining a target torque according to the vehicle speed deviation. According to the scheme, when the vehicle is in the single-pedal mode, the opening degree of the accelerator pedal and the current vehicle speed of the vehicle are collected, the vehicle speed deviation is determined according to the opening degree of the accelerator pedal and the current vehicle speed, and the operation intention of a driver can be recognized according to the vehicle speed deviation; and according to the vehicle speed deviation, the target torque is determined, the vehicle can respond to the driving intention of a driver, it is guaranteed that the driver can achieve the operation of acceleration or deceleration or constant-speed driving through an accelerator pedal, and the driving experience feeling is improved.

Description

technical field [0001] The present invention relates to the technical field of electric vehicle control, in particular to a torque control method, device and vehicle. Background technique [0002] The single-pedal function of electric vehicles mainly means that the driver can control the acceleration and deceleration of the vehicle through the accelerator pedal, that is, the motor outputs the driving torque when the accelerator pedal is pressed, and the motor outputs the braking torque when the accelerator pedal is released. This function can minimize the number of times the driver steps on the brake pedal and improve the convenience of vehicle operation. [0003] The current single-pedal control method for electric vehicles mainly obtains the output torque through the accelerator pedal opening and the real-time vehicle speed look-up table, outputs the driving torque above a certain accelerator pedal opening, and outputs the brake recovery torque below a certain accelerator ...
