Vehicle driving control method, device and system, storage medium and vehicle

Abstract

The invention provides a vehicle driving control method, device and system, a storage medium and a vehicle. The vehicle driving control method comprises the steps that after fault information of an electric driving system is detected, the fault level of the electric driving system corresponding to the fault information is determined according to safety state information and fault performance information of the electric driving system, and after the fault information of a disengagement controller is detected, the fault level of the disengagement controller is determined. And according to the obtained current gear position of the disengagement controller, determining the disengagement system fault level corresponding to the fault information, and according to the disengagement system fault level and the electric drive system fault level, executing a corresponding fault processing action. After any front drive system or rear drive system breaks down, the fault drive system can be disengaged according to the fault information judgment result, the driving capacity of the non-fault drive system is fully played, the driving speed is not reduced, normal driving is achieved, the driving performance of the whole vehicle with the four-wheel drive system is improved, and then the driving feeling is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, and in particular, to a vehicle drive control method, device, system, storage medium and vehicle. Background technique [0002] At present, the four-wheel drive electric system of new energy vehicles adopts permanent magnet synchronous motor system for front and rear drives. The permanent magnet synchronous motor uses permanent magnets to generate an air gap magnetic field, which is different from the commutator motor which generates an air gap magnetic field through the excitation coil. The induction motor uses the excitation component of the stator current to generate the same air-gap magnetic field, and has a simple structure, low loss and high efficiency. [0003] In the related art, after the front drive system or the rear drive system fails, the motor controller will report the fault level information according to the safety state of the motor, and the vehicle controller wil...

AI Technical Summary

Problems solved by technology

After the front drive or rear drive drive system fails, the vehicle controller will slow down or stop according to the fault level of the electric drive, and the drive system that has not failed can not give full play to its driving ability
