Abstract

The invention discloses a wheel torque distribution method based on forward-drive hub motors. The rotating speed difference between two front wheels is worked out by measuring the rotating angle of a steering wheel, then the torque of the two front wheels is worked out, and accordingly the hub motors are controlled to output corresponding torque. The wheel torque distribution method based on the forward-drive hub motors has the beneficial effects that wheel torque can be reasonably distributed, and tire abrasion and energy loss are reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a method for distributing wheel torque based on a front-drive hub motor. Background technique [0002] With the continuous development of the electric vehicle industry, our requirements for vehicle performance are getting higher and higher, and the vehicle system that only relies on the powertrain of the traditional motor and gearbox has been difficult to meet our growing needs. In-wheel motor technology has also developed rapidly in recent years. The technology has become more and more mature, and its application has become more and more extensive. It has gradually caught up with other motors. [0003] The hub motor has a simple structure and is easy to use. Because it is directly installed in the hub of the tire, it occupies a very small space and is light in weight. It can be replaced with a hub motor without much modification to the original vehicle system. System, s...
