Abstract
The application discloses a redundancy control method and device of an EPS motor, a storage medium and a vehicle, wherein the redundancy control method of the EPS motor first acquires an initialization state of a first EPS and an initialization state of a second EPS, then controls the first EPS and the second EPS according to the initialization state of the first EPS and the initialization state of the second EPS, so that the first EPS and the second EPS can control the motor to work, and then assist the steering of the vehicle, thereby the redundancy EPS can be controlled to check each other to successfully activate the EPS initialization, without additional flashing equipment for flashing, reducing the EPS initialization cost while improving the initialization efficiency, and preventing the EPS motor from being insufficiently assisted due to the power-on failure of a single system in a special case.
