Abstract
An algorithm for use in a forward looking collision warning system employed in a vehicle. The collision warning system includes a radar device that generates track files of the range and speed of objects in the vehicle's path. The system also includes a collision warning processor running the algorithm that receives the track files and various input data to determine whether an alert of a potential collision should be issued, and if so, to what degree. The input data includes the speed and acceleration of the vehicle, whether the vehicle's brakes are being applied, collision warning sensitivity, driver distraction modifiers, road condition data, such as wiper speed and outside air temperature, etc. is provided. The processor calculates an alert level based on the various inputs, and outputs the alert level to a driver vehicle interface to notify the driver of the potential collision.
