and when the comprehensive efficiency of the rear electric drive power system is smaller than the lower limit value of the efficiency interval corresponding to the rear electric drive power system, judging that the state of the tooth-shaped clutch at the next moment is disconnected.
7. The method according to claim 3, wherein the step of controlling the engagement of the tooth clutch includes:
and sending an axial displacement control curve signal of the tooth-shaped clutch to a driven end so that the driven end drives the tooth-shaped clutch to be engaged.
8. A tooth clutch control device, comprising:
the state acquisition module is used for acquiring the state of the tooth-shaped clutch at the next moment;
the rotating speed difference obtaining module is used for obtaining the actual rotating speed difference between the driving end and the driven end when the tooth-shaped clutch is engaged at the next moment;
the phase difference acquisition module is used for judging whether to acquire the actual phase difference between the driving end and the driven end according to the actual rotating speed difference;
and the control module is used for acquiring the actual phase difference and controlling the tooth-shaped clutch to be engaged according to the actual phase difference.
9. An electronic device, comprising: memory, a processor and a computer program stored in the memory and executable on the processor, the processor implementing the steps of the method according to any of claims 1-7 when executing the computer program.
10. A computer-readable storage medium having stored thereon instructions which, when executed on a computer, cause the computer to perform the method of any one of claims 1-7.
