The invention discloses a driving motor external characteristic parameter determination method and device based on tangent fitting, and the method comprises the steps: obtaining an interface parameter of a driving motor, and obtaining an external characteristic calculation curve of the driving motor according to the interface parameter; obtaining a tangent equation according to the external characteristic calculation curve; obtaining an external characteristic fitting curve of the driving motor according to the external characteristic calculation curve and the tangent equation; and determining external characteristic parameters of the driving motor according to the external characteristic fitting curve. The external characteristic fitting curve of the driving motor can be automatically generated only through the interface parameters of the driving motor, the workload of developers is reduced, the calculation amount is reduced, the fitting precision is improved, and meanwhile the internal storage space of the controller is saved; in addition, the motor torque fitted by the fitting curve is smaller than or equal to the actual torque, so that the service life of the driving motor can be prolonged, and the durability of the driving motor is improved.
Description
technical field [0001] The present invention relates to the technical field of electric vehicle drive motors, and in particular, to a method, device, electronic device and computer-readable storage medium for determining external characteristic parameters of a drive motor based on tangent fitting. Background technique [0002] Under the dual pressure of environmental pollution and energy shortage, the development of electric vehicles is getting faster and faster. The drive motor is an important part of the electric vehicle, which is mainly used to realize the conversion of mechanical energy and electric energy. The output torque of the drive motor is an important parameter for the control of the electric vehicle drive motor, and it is the technical guarantee for the safe and reliable operation of the whole vehicle. In the drive motor control of electric vehicles, the current desired output torque of the driver is obtained by multiplying the accelerator pedal opening and the...
