A system for minimizing roadway vehicle damage and personal injury which includes a detection sensor unit, a computer processing unit (CPU), and energy absorbing inflation devices. The detection sensor unit, which is mounted on the roadway vehicle to detect the speed, distance and direction of a potential obstacle, includes a transmitter for transmitting signals and a directional receiver to receive signals reflected by the potential obstacle and generates an electronic signal in response thereto. The CPU, which receives information on the speed and direction of the roadway vehicle and receives signals from the detection sensor unit continuously processes the information and signals and calculates changes in the speed, distance and direction of the potential obstacle with respect to the roadway vehicle. The CPU generates a control signal upon calculation of an imminent collision situation, which calculation is based on a predetermined minimum allowable time window. The minimum allowable time window is generally defined as a time period during which a driver of the roadway vehicle is unable to take evasive action, such as braking or turning the steering wheel, to avoid a collision situation. Each of the energy absorbing inflation devices includes an electronically controlled valve, with at least one of the energy absorbing inflation devices being responsive to the control signal. An external air bag is coupled to the valve of one of the energy absorbing inflation devices and an internal air bag is coupled to the valve of another of the inflation devices, such that upon calculation by the CPU of the imminent collision situation based on the predetermined minimum allowable time window, the CPU transmits the control signal to one of the energy absorbing inflation devices to deploy the air bags prior to the time of actual collision.
