Abstract

The invention discloses an electric vehicle accelerator pedal torque control method, an electronic device and a storage medium. The method comprises the following steps: in response to a torque filtering request, using a current motor actual torque as a filtering initial value; filtering the filtering initial value during every preset time period, if the filtering initial value is less than or equal to the preset target torque after filtering, exiting the operation; otherwise, performing the following operation: acquiring the corresponding query torque according to the current accelerator pedal position signal and the current motor rotating speed; according to the query torque and the filtering initial value, calculating a request torque; sending the request torque to a motor controller, which controls the motor output torque to be the request torque. By filtering the initial torque value, while the initial torque value smoothly transits to the target torque value, and the torque corresponding to stepping on the accelerator by a driver is combined to achieve a smooth transition between different modes to avoid the torque jumping, thereby enhancing the ride comfort of the vehicle.

Description

technical field [0001] The invention relates to the technical field related to electric vehicles, in particular to an electric vehicle accelerator pedal torque control method, electronic equipment and a storage medium. Background technique [0002] The driving comfort index of electric vehicles mainly includes the smoothness of gear shifting, acceleration, energy recovery, and the smoothness of switching between different torque modes of the vehicle controller. In the torque control strategy, if the accelerator is stepped on in the creeping state, the speed loop is generally used to control the target vehicle speed due to creeping, and the vehicle driving mode is switched to the torque loop control mode when the accelerator is stepped on. If the motor in the speed loop state is actually If the transition between the torque and the torque meter (pedal map) of the torque ring when stepping on the accelerator is not well handled, it will have a great impact on the driving comfo...
