VEHICLE COLLISION WARNING SYSTEM AND METHOD OF OPERATING THE SAME
First Claim
1. A method for use with a vehicle collision warning system, comprising the steps of:
- (a) receiving one or more reading(s) from a target vehicle sensor;
(b) using the reading(s) to solve a unified collision warning algorithm, wherein the unified collision warning algorithm detects a potential collision without continuously switching between different algorithms in response to dynamic conditions; and
(c) sending a warning to a driver if the unified collision warning algorithm determines that a potential collision exists.

Abstract
A vehicle collision warning system and method may be used to detect a potential or impending collision with another vehicle and to send a corresponding warning to the driver. In an exemplary embodiment, the collision warning system uses one or more target vehicle readings (e.g., a relative velocity reading (Δv), a target vehicle acceleration reading (aTAR), and a relative distance reading or range (Δd)) to solve a unified collision warning algorithm. If the unified collision warning algorithm determines that there is a potential collision with the target vehicle, then the system sends a corresponding warning to the driver.

11. A method for use with a vehicle collision warning system, comprising the steps of:
-
(a) receiving one or more reading(s) from a target vehicle sensor; (b) using the reading(s) to evaluate an expression, wherein the expression includes at least one of the following terms;

19. A vehicle collision warning system, wherein the system is mounted on a host vehicle and detects a potential collision with a target vehicle, comprising:
-
one or more target vehicle sensor(s) being mounted on the host vehicle and reflecting electromagnetic signals off of the target vehicle; and a control module being electronically coupled to the target vehicle sensor(s) and receiving target vehicle readings from the sensor(s), wherein the control module uses the target vehicle readings to solve a unified collision warning algorithm that detects a potential collision with the target vehicle without continuously switching between different algorithms in response to dynamic conditions.
