The design of anti-slip control for in-wheel motor at the limited conditions in a four in-wheel-motor drive electric vehicle

Aim at the problems on driving and anti-slip controlling of electric vehicle driven by in-wheel motor at limit working conditions, analyze and compare different several schemes on anti-slip control of electric wheel, as well as put forward the judgment method for slip ratio base on the motor current. This paper develops the sliding test bench of electric wheel. It is shown from bench test that the slip ratio judged by adopting the motor current is provided with certain feasibility, meanwhile, the slip ratio of wheel can be rapidly reduced and the anti-slip capability of electric wheel can be increased by controlling the current.
