Driving Force Control Method to Perform Slip Control in Cooperation with the Front and Rear Wheels for Front-and-Rear Wheel-Independent-Drive-Type EVs (FRID EVs)

In this study, the authors have proposed a driving force (torque) control method that is suitable for front-and-rear-wheel independent-drive-type electric vehicles (FRID EVs). By using this method, it is possible to prevent slipping or spinning of the wheel, which can cause rear-end collisions on bad roads. The method achieves this by communicating information from a vehicle to the vehicle behind it. When the first vehicle performs wheel spin control, the resultant information is transmitted to the vehicle behind it. For this reason, each vehicle must have the capability to suppress wheel spin individually. In order to provide this wheel spin control, the authors propose a driving force control method, which allows them to control the slipping of a vehicle by distributing appropriate amounts of driving force between the front and rear wheels on the basis of the friction coefficient. This coefficient is estimated by considering data regarding the road conditions. The authors verified the effectiveness of the proposed driving control method for various low-mu roads by performing simulations.
