Range measurement system

Abstract

A vehicle control system (12) is provided which comprises a range measurement system (14) which transmits a signal (20) to a target (22) and receives an echo signal (24) returned from the target (22). The range measurement system (14) comprises a transmitter system (26) and a receiver system (28). The receiver system (28) generates an analog signal representative of the range. The target (22) transmits the range signal to a processor (30). Processor (30) may be used to provide warning signals and to control a conventional speed control system (16) coupled to the throttle (18) of a vehicle (10).U
