Front/Rear Driving Force Distribution Control Based on Tire Workload Considering Vehicle Behavior in the Turning Limit

Abstract

In the turning limit, front-wheel-drive vehicles tend to plow, and rear-wheel-drive vehicles tend to spin, resulting in consistent vehicle behavior. On the other hand, four-wheel-drive vehicles have a small difference in the workload between the front and rear tires, and their vehicle behavior is inconsistent. In this paper, we proposed a design method for front/rear driving force distribution based on tire workload in order to control vehicle behavior in the turning limit.
