Problems solved by technology

[0002] Four-wheel drive is an important way to drive electric vehicles. At present, major OEMs mainly use two types of four-wheel drive, front and rear axle dual motor drive or four-wheel hub motor independent drive, and front axle motor drive plus rear dual hub motor drive. There are few studies on four-wheel drive
Moreover, for four-wheel drive, front and rear torque distribution and rear dual hub motor torque distribution are the key points that determine the performance and driving quality of the vehicle. Power output evenly during the process

Abstract

The invention discloses a vehicle control method and device, a storage medium, a control system and a vehicle. The vehicle comprises a first motor used for driving two front wheels of the vehicle, a second motor used for driving a first rear wheel of the vehicle, and a third motor used for driving a second rear wheel of the vehicle. The control method comprises the steps that the accelerator pedalopening degree, the vehicle speed, the steering wheel rotating angle, the driving mode and the drive mode of the vehicle are obtained; request torques of the first motor, the second motor and the third motor are calculated correspondingly according to the accelerator pedal opening degree, the vehicle speed, the steering wheel angle, the driving mode and the drive mode; the motors are controlled according to the request torques, and the actual torques of the motors are obtained; and the torque and the drive mode is checked according to the actual torque and the request torque, and the vehicleis controlled to run normally when checking is passed. According to the control method of the vehicle, power output of the vehicle in the driving process can be more uniform, the comfort and dynamic property of the vehicle are guaranteed, and the driving texture of the vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle control method, a vehicle control device, a computer-readable storage medium, a vehicle control system and a vehicle. Background technique [0002] Four-wheel drive is an important way to drive electric vehicles. At present, major OEMs mainly use two types of four-wheel drive, front and rear axle dual motor drive or four-wheel hub motor independent drive, and front axle motor drive plus rear dual hub motor drive. There are few researches on this four-wheel drive form. Moreover, for four-wheel drive, front and rear torque distribution and rear dual hub motor torque distribution are the key points that determine the performance and driving quality of the vehicle. The power is evenly output during the process. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. ...
