Abstract

The invention provides an electric vehicle control method and device, a storage medium and an electric vehicle controller. The method comprises the steps: acquiring the opening degree of an accelerator pedal of an electric vehicle, and determining whether to enter a speed control mode or not according to the opening degree of the accelerator pedal; and if the method determines that the electric vehicle enters the speed control mode, performing torque control based on the current acceleration of the electric vehicle. According to the scheme, the vehicle can be kept running at a constant speed under the condition that the current opening degree of the accelerator pedal is not changed, the vehicle speed is prevented from being continuously increased, driving safety is guaranteed, and driving experience is improved.

Description

technical field [0001] The invention relates to the control field, in particular to an electric vehicle control method, device, storage medium and electric vehicle controller. Background technique [0002] Electric vehicles such as new energy vehicles mostly use motors as the power source. Different from the complex engine characteristics of traditional fuel vehicles, new energy vehicles only need to control the torque or speed of the motor to complete the drive of the car. The motor has the characteristics of high torque at low speed and constant power at high speed, and has good economic efficiency for the driving ability of the vehicle. [0003] The torque control mode in the related art does not control the vehicle speed, and the requested torque is continuously output when the accelerator opening remains unchanged, and is not adjusted according to the vehicle speed, resulting in a constant increase in the vehicle speed, unable to stabilize the vehicle speed, and causing...
