Abstract
A collision avoidance and warning system for land vehicles including radar transmission and receiving apparatus for sensing the presence of objects within a spatial range relative to a vehicle, multiple target tracking apparatus receiving an output from the radar transmission and receiving apparatus for tracking a plurality of targets sensed by the radar transmission and receiving apparatus, auxiliary non-radar target sensing apparatus and alarm decision apparatus receiving an input from the multiple target tracking apparatus and from the auxiliary non-radar target sensing apparatus for indicating the alarm status of a target and providing an output indication to alarm generating apparatus.
Claims22
A collision avoidance and warning system for land vehicles comprising:
- a radar transmitter/receiver module for sensing the presence of objects within a spatial range relative to a vehicle;
- an auxiliary laser radar including a laser beam generator associated with a target intrusion sensor which detects intrusion of a target into a danger region having laser beam defined walls by generating a trigger signal indicating that one of the walls has been encountered by an object;
- and
- an alarm activator receiving an input from said radar transmitter/receiver module and from said target intrusion sensor for indicating the alarm status of a target and for providing an output indication to alarm generating apparatus.
A collision avoidance and warning method for land vehicles including:
- radar sensing the presence of objects within a spatial range relative to a vehicle;
- sensing targets by target intrusion sensing techniques which generate laser beams and detect intrusion of a target into a danger region having laser beam defined walls by generating a trigger signal indicating that one of the walls has been encountered by an object;
- and
- receiving a target intrusion sensing input and on the basis thereof indicating the alarm status of a target and providing an output indication to a driver.
