A study of self-reliant cornering speed control system

A major cause of accidents during cornering is the excessive vehicle speed due to the driver´s incorrect recognition or misjudgement of the curvature of the road, the vehicle performance and the road conditions. We are now studying a self-reliant cornering vehicle speed control system without using outside facilities along the road. This paper presents the base technology of such a system which predicts the curvature of the oncoming road based on the map information from the car navigation system which has already been installed in production vehicles in Japan
