A cruise control system for a motor vehicle

In a vehicle cruise control system, a vehicle 20 is controlled at a set speed or operates to follow a safe distance behind a target vehicle 30 using a radar system 16A,26A. At low speeds or when the vehicle is halted, short range sensors 17B, 17C are used to detect if obstacles eg pedestrians 39 are...

Zusammenfassung:	In a vehicle cruise control system, a vehicle 20 is controlled at a set speed or operates to follow a safe distance behind a target vehicle 30 using a radar system 16A,26A. At low speeds or when the vehicle is halted, short range sensors 17B, 17C are used to detect if obstacles eg pedestrians 39 are present in a safety area substantially in front of the vehicle 20. If an obstacle 39 is detected in this safety area then the engine power is reduced and the brakes are applied if the vehicle is moving or the vehicle 20 is prevented from pulling away to follow the target vehicle 30 if it is already at rest. A system whereby a series of emitters 31 inform the vehicle that it is approaching a red traffic signal 34 is also disclosed.
