Vehicle emergency alarm and stop system

Abstract

A vehicle emergency control system which remotely signals the unauthorized operation of a suitably-equipped vehicle, and which conditions the vehicle by remote control to be involuntarily retarded or stopped by an action of the unauthorized operator. Vehicles are equipped with a transmitter which broadcasts an emergency condition message in response to an unauthorized or emergency situation. The emergency message identifies the vehicle, and may also identify the nature of the emergency condition. The emergency message is received at a central location, from which a coded command signal can be transmitted to a receiver in the vehicle to disable the operation of the particular vehicle from which the emergency message emanated. The command signal conditions the brake accelerator, or some other vehicle control to be retained in a retarded position when that control is next operated. The vehicle emergency system also includes a concealed antenna which automatically becomes extended when the vehicle emergency system is operated.
