Research of Electric Power Steering System Assistance Characteristic Based on The Identification of The Road
Study of traditional assist characteristic cure does not take into account the difference of steering resistance torque caused by different road adhesion coefficient.Vehicle dynamics analysis model is established based on ADAMS/CAR.Simulation of steering wheel torque is realized under different road conditions.Departure from the ideal boost characteristics requirements and combined with ideal steering wheel torque under different speed and lateral acceleration.,the article built assist characteristic curve under a certain road conditions.The system can real-time select the assist characteristic curve through identifying the vehicle traveling road conditions by the way of BP neural network.The theory provided a feasible method for the improvement of the EPS system performance.
