Abstract :
This paper presents stability analysis of car driving with a joystick interface. A car drive assist system with a joystick interface enables disabled persons to drive a car with joystick operations. A steering wheel and gas/brake pedals are actuated by electric motors which rotations are controlled by micro-computers based on 2DOF joystick commands. Since the drive assist system involves a time delay and an amplifier with a high gain, a car would show unstable behaviors when a stable condition is not guaranteed. To analyze the stable and unstable behaviors of car driving, we derive a vehicle dynamic model together with the joystick system and human recognition model (driver model) for various car velocities.
