Abstract

The invention provides a vehicle, a motor control method and device thereof and a computer readable storage medium. The invention discloses a motor control method. The method comprises the steps: detecting a current torque value and a current rotating speed value of the motor; obtaining a target voltage utilization rate according to the current torque value of the motor and the current rotating speed value of the motor; sampling bus voltage, obtaining a bus voltage sampling value; controlling the running state of the motor according to the bus voltage sampling value, the target voltage utilization rate, the current torque value of the motor and the current rotating speed value of the motor; therefore, the motor is controlled according to the specific operation condition of the motor, the operation efficiency of the motor is improved, and the problem that an existing motor control method is low in operation efficiency of the motor is solved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular to a vehicle, a motor control method and device thereof, and a computer-readable storage medium. Background technique [0002] In recent years, with the improvement of people's living standards, automobiles have become a very important means of transportation in people's lives. With the popularity of automobiles, the control performance of their motors has become the top priority in automobile manufacturing. [0003] As a key component in the car, the motor controller contains motor control and control data that characterizes the performance of the motor. Therefore, the motor controller plays a very important role in motor control. At present, the existing motor control method is mainly that the motor controller uses a fixed bus voltage utilization rate to control the motor. [0004] However, although this method can effectively control the motor, it does not take int...
