Driving support control of electric vehicle adapting to environment with a haptic accelerator pedal

With the increase in the number of drivers, traffic accidents have increased in number. The process of driving includes acknowledgment, judgment, and operation. Among these, acknowledgment is the most important because mistakes in acknowledgment accounts for 70% of the human factors causing accidents. This paper proposes the cooperation between a haptic pedal system and the driver, which gives the driver information about the road condition. It is confirmed that the proposed method helps in accurate acquisition of road condition information and transmission of this information to drivers; then, the driver's response is analyzed to check whether the information transmission is efficient and the support provided to the driver is adequate. Simulation and experiments were carried out to verify the validity of the proposed approach.
