This paper discusses the driver's role in controlling a road vehicle, and how to use various types of chassis sub-systems to emulate professional racing drivers' (PRDs') control strategies. Emergency situations often cause a car to exceed its limits of adhesion, and then go out of control. If a driver can anticipate loss of adhesion, and apply the correct sequence of controls, he can avoid this situation. Critical controls include: steering, brakes, throttle, transmission and sometimes clutch. Any driver senses the acceleration on his body, usually places his vehicle, and receives effort feedback through the steering wheel. A PRD can better extract individual components of acceleration, and more readily predict if his vehicle is deviating from its desired path. Mathematical models of drivers have been used to evaluate the perceptual cues that they receive. Currently used chassis systems include antilock brakes and traction control. Future subsystems, that will continue to increase a vehicle's 'active safety', include: (1) closed-loop rear wheel steer; (2) controlled dampers; (3) drive torque control; and (4) active load distribution. These subsystems, individually and mutually coordinated in integrated vehicle control systems, contribute to a vehicle's driving comfort and active safety. For the covering abstract see IRRD 867146.
