A road surface identification method for a four in-wheel-motor drive electric vehicle

Abstract: Abstract:A four in-wheel-motors drive electric vehicle needs to identify the road surface in order to optimise the slip-ratio control. This paper builds a four in-wheel-motor drive electric vehicle dynamic model and estimates the vehicle speed and driving forces of four wheels by the method of adaptive filtering. According to the calculated tyre adhesion coefficient and slip ratio, the paper employs the method of combining fuzzy inference with slope determination to evaluate the road type and determine the tar… Show more

“…Tyre patterns and properties of rubber such as the hardness and elasticity especially in dependence on the temperature play a significant role in vehicle motion stability and the vehicles ability to steer. The approach to the problem of interaction between tyre and road is described by Ella et al (2013), Skouvaklis et al (2012), Higgins et al (2008), Deng et al (2013), where indoor tests of tyres are presented. They give us an active insight and an extension into further development.…”

“…19,20 In vehicle dynamics control, vehicle state parameter observation system estimates vehicle key state parameters online and transmits effective information to vehicle controller. 21,22 The vehicle controller analyzes the current vehicle status according to the acquired information and then issues corresponding control instructions, so as to achieve effective control of the vehicle. 23 Real-time observation of vehicle status is the basis of vehicle control and the accuracy of state parameter observation directly affects the control effect and characteristics of vehicle dynamics control system.…”
