Abstract

The invention discloses an automobile control method and device, a storage medium and an automobile. The method comprises the steps of determining an accelerator pedal opening degree change value anda motor rotating speed change rate of the automobile; determining an expected driving state and an actual driving state of the automobile according to the determined accelerator pedal opening degree change value and the motor rotating speed change rate; determining an output torque compensation coefficient for compensating the actual output torque value of the automobile according to the determined expected driving state and the actual driving state; and within the set output torque range, compensating the actual output torque value of the automobile according to the determined output torque compensation coefficient. According to the scheme, the problem of power waste caused by hysteresis of output power change of the electric automobile can be solved, and the effect of saving power is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an automobile control method, device, storage medium and automobile, in particular to a motor energy-saving intelligent control method, device, storage medium and automobile. Background technique [0002] Electric vehicles mainly include three core systems: vehicle control unit (Vehicle Control Unit, VCU), motor drive controller (Motor Control Unit, MCU), and battery management system (Battery Manager System, BMS). The VCU takes the accelerator pedal, brake pedal, gear position, motor speed and other signals as input, and calculates the output power data required by the vehicle through internal functional modules, and sends the power data to the Controller Area Network (CAN) message. The form is sent to the motor drive controller through CAN bus communication, and then controls the output power of the motor. [0003] In the past practice, the method of VCU to cal...
