Collision Warning Apparatus
First Claim
1. A collision warning apparatus for a host vehicle which has stopped along a lane of a highway, comprising:
- a memory in which said apparatus stores a reference target data set dependent upon movement of a first vehicle within said scene in a first period of time;
at least one sensor associated with said host vehicle which generates a data stream in response to radiation received from a scene rearwards of said host vehicle; and
processing circuitry arranged to;
identify a second target vehicle moving in said scene during a second period of time subsequent to said first period of time from said data stream and to output at least target data for said identified vehicle, said processing circuitry further arranged to process said reference target data set with said target data to determine whether there is a risk of collision between said second target vehicle and said host vehicle.

Abstract
A collision warning apparatus for a host vehicle which has stopped along a lane of a highway, comprises at least one sensor associated with the host vehicle which generates a data stream in response to radiation received from a scene rearwards of the host vehicle, a memory in which the apparatus stores a reference target data set dependent upon movement of a first vehicle within the scene in a first period of time; and processing circuitry arranged to: identify a second target vehicle moving in the scene during a second period of time subsequent to the first period of time from the data stream and to output at least target data for the identified vehicle; and process the reference target data set with the target data or data derived therefrom, to determine whether there is a risk of collision between the second target vehicle and the host vehicle. The apparatus is especially suited for use with a vehicle that is stationary by the side of a road to warn of a possible collision from a vehicle that is approaching it from the rear.

19. A method of collision warning for a host vehicle which has stopped along a lane of a highway, comprising:
-
storing a reference target data set dependent upon movement of a first vehicle within a scene in a first period of time; generating a data stream in response to radiation received from said scene rearwards of said host vehicle; identifying a second target vehicle moving in the scene during a second period of time subsequent to said first period of time from said data stream and outputting at least target data for said second target vehicle; and processing said reference target data set with said target data to determine whether there is a risk of collision between said second target vehicle and said host vehicle. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
