Design of a new steering system to solve the problem of steering operation during low speed driving

This study aims to develop a new steering system that can help increase the ease of driving and reduce the driver's mental workload during low-speed driving. First, the problems associated with low-speed driving were investigated. It was found that the act of changing the steering grip is o...
