Outline of Final Research Achievements

This study aimed to construct a collision avoidance assist system, which consists of the following functions; 1) it encourages a driver to decelerate the vehicle early by providing a haptic guidance without conflict between the driver and the system, and 2) it performs automatic collision avoidance with consideration for tire force saturation when the manual collision avoidance becomes difficult. First, this study proposed the calculation method of a lateral acceleration for collision avoidance, which is a required lateral acceleration to avoid collision with a preceding vehicle. Second, it proposed an automatic control law to avoid a collision by the combination of braking and steering with consideration for tire force saturation. Finally, it constructed a haptic guidance system to encourage the driver to perform avoidance maneuver without conflict between the driver and the system. The driving simulator experiments were conducted to verify the effectiveness of the proposed system.
