Abstract

The invention discloses a control method based on an EV front-rear drive intelligent coordination drive system. Corresponding instructions are outputted to relays in a front drive device and a rear drive device through an MCU connected with the front drive device and the rear drive device so as to control a motor to achieve intelligent coordination of front drive running, rear drive running, four-wheel drive running, reverse gear running and brake control. The drivability and the smoothness of the front drive can be realized, the dynamic property of the rear drive can also be realized, meanwhile, four-wheel drive can also be realized, and the drivability and the safety of the whole vehicle are ensured.

Description

technical field

[0001] The invention relates to a technology in the field of electric vehicles, in particular to a control method based on an EV front and rear drive intelligent coordinated drive system. Background technique

[0002] Most of the existing EV four-wheel drive systems use a dual-motor control system to drive the front and rear axles separately to provide power for the vehicle. Each requires two independent motor drive systems, which are costly. In addition, EV adopts a fixed front-drive system or rear-drive system, which cannot be dynamically coordinated and converted, which affects the passability and drivability of the vehicle. Contents of the invention

[0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention proposes a control method based on an EV front and rear drive intelligent coordinated drive system, which can not only realize the drivability and smoothness of the front drive, but also realize the dynamic performanc...
