Electric vehicle and electric-machinery control method therefor, apparatus and storage medium

An electric-machinery control apparatus for an electric vehicle, comprising:

• at least one processor and a memory;
• the memory stores computer executable instructions;
• the at least one processor executes the computer executable instructions stored in the memory to:
• detect a relative deformation amount of a transmission system between a driving gear and a wheel end of an electric machinery;
• determine a first speed differential value between a first driving-gear rotational speed and a first wheel-end converted rotational speed when the relative deformation amount is a first threshold value, wherein the relative deformation amount being the first threshold value is used for indicating that the driving gear and a driven gear of the transmission system start to disengage, the first driving-gear rotational speed is a rotational speed of the driving gear at a disengagement moment that the driving gear and the driven gear disengage, and the first wheel-end converted rotational speed is a rotational speed obtained by performing a speed ratio conversion on a rotational speed of the wheel end of the electric vehicle at the disengagement moment;
• determine an output torque of the electric machinery according to the first speed differential value;
• control the driving gear to perform a gear-approaching operation relative to the driven gear according to the output torque.

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores computer execution instructions, and when the computer execution instructions are executed by a processor, the processor is enabled to:

• detect a relative deformation amount of a transmission system between a driving gear and a wheel end of an electric machinery;
• determine a first speed differential value between a first driving-gear rotational speed and a first wheel-end converted rotational speed when the relative deformation amount is a first threshold value, wherein the relative deformation amount being the first threshold value is used for indicating that the driving gear and a driven gear of the transmission system start to disengage, the first driving-gear rotational speed is a rotational speed of the driving gear at a disengagement moment that the driving gear and the driven gear disengage, and the first wheel-end converted rotational speed is a rotational speed obtained by performing a speed ratio conversion on a rotational speed of the wheel end of the electric vehicle at the disengagement moment;
• determine an output torque of the electric machinery according to the first speed differential value;
• and
• control the driving gear to perform a gear-approaching operation relative to the driven gear according to the output torque.
