The micro-electric vehicle with the active front wheel steer and the torque assist/augmetation system is developed. It is proved that the active front-wheel steering system can compensate for the decline of the driveability of the aged drivers. The derivative term in the active steering system is especially expected to allow the drivers lower proportional gain and larger time delay which results in the vehicle easier to control for aged drivers. This reasoning corresponds to the drivers comments to the evaluation of ease of control during lane change. The torque augmentation system has significant effects on reducing the faltering behaviour of the aged drivers during the course tracking with some disturbances and improves the on-center handling characteristics of the micro-electric vehicle for aged drivers.
