Abstract: A motor control unit, a control system, and a storage medium. The method of the present invention is applied to the motor control unit and comprises: when a vehicle is in a high-voltage power-on state, obtaining a plurality of effective temperature values for the same motor system; determining a corresponding initial temperature value according to each effective temperature value; determining the minimum value among all calculated initial temperature values as an initial environment temperature; when the vehicle is in a driving state and each initial temperature value is less than or equal to respective corresponding threshold, and the current temperature of a motor no longer rises, calculating differences between the current temperature of the motor and the corresponding initial temperature value and between the current temperature of a cooling liquid and the corresponding initial temperature value; calculating a temperature calibrate amount for the environment temperature according to the calculated differences.

Abstract: The present disclosure relates to the technical field of vehicles, and particularly to a vehicle control method and apparatus, a storage medium and a vehicle. The method includes: acquiring a pressure of a brake master cylinder and an opening degree of an accelerator pedal; when the pressure of the brake master cylinder is greater than a first preset pressure threshold, the opening degree of the accelerator pedal is no less than a first preset opening degree threshold, and a moment when the pressure of the brake master cylinder is greater than the first preset pressure threshold is earlier than a moment when the opening degree of the accelerator pedal is no less than the first preset opening degree threshold, controlling the vehicle to enter an activated state of a launch starting function; and when the vehicle is in the activated state, controlling an engine of the vehicle to output a target torque. Thus, a driver enables the vehicle to enter the activated state of the launch starting function before starting by operating a brake pedal and the accelerator pedal at the same time, and also enables the vehicle to provide a torque output according to a state of the accelerator pedal while being in a brake state, thus enabling the vehicle to start quickly with greater power, reducing an acceleration time and realizing launch starting.
