Abstract

The invention provides a vehicle driving control method and a multi-wheel independent driving vehicle. The method is applied to the multi-wheel independent drive vehicle, and the vehicle comprises a plurality of drive motors corresponding to wheels. The method comprises that: a drive instruction used for driving the drive motors is obtained, and the required torque corresponding to the drive instruction is determined, wherein the required torque represents the motor torque needing to be changed; a current gear of the vehicle is determined; and an actual torque of the driving motor is determined according to the required torque and the current gear. The actual torque of the driving motor is jointly determined according to the current gear of the vehicle and the required torque determined based on the driving instruction, the actual torque of the driving motor can be controlled to be matched with the current gear of the vehicle as much as possible, and then the stability of the multi-wheel independent driving vehicle in the running process can be improved.

Description

technical field [0001] The present application relates to the field of motor vehicle control, in particular, to a vehicle drive control method and a multi-wheel independently driven vehicle. Background technique [0002] The use of automobiles continues to grow, and automobile exhaust emissions have seriously affected people's lives. Therefore, reducing automobile exhaust emissions has become an urgent problem to be solved. The emergence of electric vehicles provides an effective solution to the emission problem. [0003] Multi-wheel independent drive vehicles (such as four-wheel distributed independent drive electric vehicles) have become one of the development directions of electric vehicles due to their flexible response and precise control. However, since multiple motors independently control each wheel of a multi-wheel independent drive vehicle, the vehicle control of the multi-wheel independent drive vehicle becomes a difficult problem. How to improve the stability o...
