Abstract

The invention discloses a motor control method and device, a vehicle control unit, a vehicle and a storage medium. The motor control method comprises the steps: in response to a detection result of reverse output peak torque of a motor, detecting the residual electric quantity of a power battery; and in response to a detection result that the residual electric quantity of the power battery is higher than a preset high electric quantity threshold, controlling a motor to reversely output the optimal efficiency interval torque. The device comprises a processor and a memory, wherein the processorimplements the motor control method when executing a computer program stored in a memory. The vehicle control unit comprises the device. The vehicle comprises the device or the vehicle control unit. The storage medium is used for storing a computer program, and the motor control method is realized when the computer program is executed by the processor. According to the invention, the problem thatthe motor output torque compensation mode of existing 48 V hybrid electric vehicle easily causes the forced discharge of the power battery and further causes the increase of the energy consumption ofthe vehicle can be solved.

Description

technical field [0001] The invention belongs to the field of hybrid electric vehicle control, and more specifically relates to a motor control method, equipment, vehicle controller, vehicle and storage medium. Background technique [0002] With the implementation of increasingly stringent automobile fuel consumption regulations and emission regulations, the automotive field has higher and higher requirements for fuel-saving and emission-reduction technologies. In this background, 48V hybrid electric vehicle has attracted more and more attention because of its excellent fuel-saving and emission-reducing performance. The 48V hybrid vehicle has two power sources, the engine and the motor, and its control method is relatively complicated, with the engine as the main power source and the 48V motor as the auxiliary power source. When the engine participates in the driving process, if the required torque of the vehicle does not meet the engine's best fuel consumption requirements,...
