Abstract

A vehicle includes a suspension system operatively connecting a vehicle body to a plurality of wheels for maintaining contact between the wheels and a road surface, and for maintaining handling of the vehicle. A system for steering the vehicle and a braking system for decelerating the vehicle are also included. The vehicle additionally includes a plurality of thrusters, wherein at least one of the thrusters is arranged relative to each wheel and each of the plurality of thrusters is configured to generate a force. Furthermore, the vehicle additionally includes a controller configured for regulating the force generated by each of the thrusters to assist the suspension system with maintaining contact between the wheels and the road surface and maintaining handling, assist the steering system with steering, and assist the braking system with decelerating the vehicle. A method of assisting the vehicle suspension, steering, and braking systems is also disclosed.
