Keywords: Patents, Sensors, Automotive industry

A detection system for controlling the speed of a vehicle is presented. The adaptive cruise control system detects objects in a region about the front of a vehicle and can determine when the vehicle is approaching an object or that an object is approaching the vehicle. Data from the sensor are used to initiate steps that are carried out in accordance with a set of rules that control the speed of the vehicle and thereby maintaining a safe trailing distance behind the detected object.

The system comprises a radio frequency transceiver sensor module positioned so that a detection zone is deployed in front of a vehicle. The sensor includes a sensor antenna system, which comprises an antenna for emitting or transmitting an RF signal and receiving portions of the transmitted RF signal that are intercepted by one or more objects within a field of view of the antenna.
