Embodiment Construction

[0046] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0047] figure 1 is a flow chart of a method for controlling a motor according to an exemplary embodiment, such as figure 1 As shown, the method includes:

[0048] In step 101, the current stepping depth of the accelerator pedal of the vehicle and the current temperature of the motor are acquired.

[0049] For example, during the driving process of the vehicle, the current stepping depth of the driver stepping on the accelerator pedal (ie, the opening degree of the accelerator pedal) and the current temperature of the motor can be collected in real time through the information collecting device provided on the vehicle. After obtaining the current pedaling depth and ...

Abstract

The present disclosure relates to a motor control method, device, and vehicle, and relates to the field of motor control. The method includes: obtaining the current pedaling depth of the accelerator pedal of the vehicle and the current temperature of the motor, determining the target torque according to the current pedaling depth, and determining the target torque according to the target torque, The corresponding relationship between the current temperature and the preset, determine the target current, and control the motor according to the target current, so that the motor can output the target torque. The present invention can adjust and control the current of the motor according to the temperature of the motor, so that the torque output by the motor can be kept stable, and the driving stability and comfort of the vehicle can be improved.

Description

technical field [0001] The present disclosure relates to the field of motor control, and in particular, to a motor control method, device and vehicle. Background technique [0002] With the rapid development of society, the number of vehicles is increasing. During the driving process of the vehicle, if the motor runs for a long time, the temperature of the motor will become higher and higher, which will affect the efficiency of the motor. That is, when the driver steps on the accelerator pedal to the same position, the output torque when the motor temperature is high is less than the output torque when the motor temperature is low, resulting in the vehicle's power not meeting the driver's needs. Correspondingly, as the temperature of the motor increases, the limit capacity of the motor will also decrease, that is, the peak torque of the motor will also decrease with the increase of temperature, resulting in a decrease in the climbing and acceleration capabilities of the vehi...
