Abstract

The disclosure proposes a vehicle and its motor control method and device, and a computer-readable storage medium. The motor control method detects the current torque value and current speed value of the motor when the motor is running, and according to the current torque value and current speed value of the motor, The current speed value of the motor obtains the target voltage utilization rate, samples the bus voltage to obtain the bus voltage sampling value, and then controls the motor according to the bus voltage sampling value, the target voltage utilization rate, the current torque value of the motor, and the current speed value of the motor In this way, the motor is controlled according to the specific operating status of the motor, thereby improving the operating efficiency of the motor, and solving the problem of low motor operating efficiency in the existing motor control method.

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...
