Problems solved by technology

[0003] However, in the above-mentioned related technologies, since the output control of the trailer motor and the engine of the tractor are interrelated, when the tractor is changed, the power distribution of the entire power system will be affected, which may cause the trailer motor to fail to operate normally, and it is difficult to meet the requirements of the transportation process. In the application scenario that requires a single trailer to be used with multiple tractors, the adaptability is low

Abstract

The invention relates to a motor control method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining driving state information of a vehicle, and the vehicle comprises a tractor and a trailer connected with the tractor; the driving state information of the vehicle comprises the vehicle speed of the vehicle, the opening degree of an accelerator pedal and the opening degree of a brake pedal of the tractor and the battery capacity of the trailer; determining an operation mode of the vehicle according to the driving state information; when the driving state information meets the motor control triggering condition corresponding to the operation mode, determining the target output torque of the trailer motor in the operation mode; and according to the target output torque, controlling the trailer motor to output torque. By adopting the method, the adaptability of the trailer and the tractor can be improved.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a motor control method, device, electronic equipment and storage medium. Background technique [0002] In the related art, the trailer includes a tractor and a trailer connected to the tractor, the tractor includes a tractor engine, an engine controller, and a vehicle controller, the trailer includes a trailer motor and a motor controller, and the vehicle controller The status is power distribution between the tractor engine and the trailer motor, and the power distribution result is sent as a control signal to the engine controller and the motor controller respectively, so as to control the tractor engine and the trailer motor to output corresponding torque. [0003] However, in the above-mentioned related technologies, since the output control of the trailer motor and the engine of the tractor are interrelated, when the tractor is changed, the power distribution of t...
