Abstract

The invention relates to a vehicle control method and device, a medium, a controller and a vehicle, and aims to better manage torque peak assisting power, so that the vehicle obtains high instantaneous acceleration, and a power battery is prevented from being over-discharged. The method comprises the following steps: acquiring the residual electric quantity and first temperature information of a vehicle power battery; acquiring second temperature information of the vehicle driving motor; power-assisted intention information used for indicating whether a driver has a power-assisted torque peak value demand or not is obtained; according to the residual electric quantity, the first temperature information and the second temperature information, whether the vehicle has the power-assisted torque peak value capacity or not is determined; and if it is determined that the vehicle has the power-assisted torque peak value capacity and the power-assisted intention information indicates that the driver needs the power-assisted torque peak value, the vehicle is controlled to enter a torque peak value power-assisted mode.

Description

technical field [0001] The present disclosure relates to the field of vehicles, and in particular, to a vehicle control method, device, medium, controller, and vehicle. Background technique [0002] When a hybrid vehicle starts, the drive motor can provide greater torque than the engine. Therefore, the drive motor is usually used to assist the vehicle with torque to increase the instantaneous acceleration of the vehicle. In addition, the power battery is usually used to provide power for the torque boost of the drive motor, that is, the power battery outputs a certain power to the drive motor, so that the drive motor provides torque boost. However, in this process, if the power provided by the power battery is too small, it will not be able to meet the requirements of increasing the instantaneous acceleration, and if the power provided by the power battery is too large, it may exceed the tolerable range of the power battery, resulting in failure or even damage to the power b...
