Abstract: The present disclosure relates to the field of vehicle technology and provides an energy recovery control method, a system, and a vehicle. The method is applied in a vehicle, and the vehicle comprises a drive motor and a battery electrically connected to the drive motor; a first energy recovery torque curve with respect to the drive motor is pre-configured in the vehicle, and the first energy recovery torque curve is used to indicate a correspondence relationship between vehicle speed and energy recovery torque of the drive motor. The present disclosure performs reduction on a first energy recovery torque curve by means of utilizing a reduction ratio, allowing energy recovery in accordance with a relatively low torque strength when a usable charge power of the battery is unable to satisfy a preset power requirement corresponding to the first energy recovery torque curve.

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.

Abstract: A method and an apparatus for controlling a vehicle mounted game, a computer program, a storage medium, and a vehicle are provided in the present disclosure. The method is applied to the VCU. The VCU controls a vehicle to be powered at a low voltage in case that it is determined that the vehicle enters a game activation state; when the vehicle is powered at the low voltage, the VUC collects an operation signal of the vehicle, in which, the operation signal includes: an accelerator pedal position signal, a brake pedal position signal, a steering wheel angle signal, and a gear position signal of the vehicle; and the VUC sends the operation signal to a vehicle HUT to enable the vehicle HUT to control the vehicle mounted game according to the operation signal.
