MOTOR ROAD VEHICLE COLLISION WARNING SYSTEM

摘要

A motor road vehicle collision warning system (1) comprising an obstacle sensing system (3), comprising a plurality of sensors (5) together capable of sensing obstacles in any direction around the vehicle (7) wherein each of said plurality of sensors (5) has a predetermined field of view (9) in which it is capable of detecting obstacles and an instantaneous field of view (10, 11), within which obstacles sensed by the sensor causes the obstacles sensing system (3) to generate an obstacle signal, a vehicle operation sensing means (13) for detecting at least one property of the vehicles operation, a zone of concern control means (15) for defining a zone of concern (17) within which sensed obstacles trigger the generation of an obstacle of concern signal whereby the zone of concern (17) is defined in dependence on the property or properties of the vehicles operation sensed by the vehicle operation sensing means (13), and for controlling the sensors such that the instantaneous field of view of the sensors (5) together cover the zone of concern (17) and a warning control system (19) for receiving said obstacle of concern signals and for determining whether a collision warning signal should be generated.
