Abstract
A method of estimating an intersection location for a vehicle safety system is disclosed. The method includes steps of calculating a stopping distance according to operating parameters of the motor vehicle. The method also includes a step of determining a location for an intersection using the stopping distance and the location of the vehicle. The method further includes steps of determining a distance between a remote vehicle and the intersection. A vehicle safety system is controlled according to the distance between the motor vehicle and the intersection and the distance between the remote vehicle and the intersection.
Claims6
A method of operating a motor vehicle, comprising the steps of:
- receiving a vehicle speed, a vehicle location and braking information;
- estimating a first distance between the motor vehicle and an intersection using the vehicle speed and the braking information;
- determining a second distance between the motor vehicle and a remote vehicle;
- estimating a third distance between the remote vehicle and the intersection using the first distance and the second distance;
- controlling a vehicle safety system of the motor vehicle according to the first distance and the third distance;
- and
- wherein the vehicle safety system is a collision warning system and wherein the step of estimating the third distance is followed by a step of determining a threat level according to the first distance and the third distance and wherein the collision warning system is controlled according to the threat level.

- estimating a first distance between the motor vehicle and an intersection using the vehicle speed and the braking information;
- determining a second distance between the motor vehicle and a remote vehicle;
- estimating a third distance between the remote vehicle and the intersection using the first distance and the second distance;
- controlling a vehicle safety system of the motor vehicle according to the first distance and the third distance;
- and
- wherein the vehicle safety system is a collision warning system and wherein the step of estimating the third distance is followed by a step of calculating a first time for the motor vehicle to arrive at the intersection and a second time for the remote vehicle to arrive at the intersection.
