Traffic alert police radar
First Claim
1. A method of warning the operator of a primary vehicle of the potential collision of a closing vehicle with the primary vehicle, the closing vehicle proceeding in the same direction as the primary vehicle, said method comprising:
- (a) determining the presence of a U-turn pursuit maneuver by monitoring the primary vehicle for a relatively sudden slowing of primary vehicle velocity from a first velocity to a second velocity followed by a subsequent velocity increase from the second velocity to a third velocity, wherein the third velocity is greater than or equal to the first velocity and the first velocity is greater than the second velocity;
(b) determining one or more parameters regarding the state of movement of the closing vehicle; and
(c) generating an alert to the operator of the primary vehicle when the presence of a U-turn pursuit maneuver of the primary vehicle and the one or more parameters of the closing vehicle are at a predetermined status.

Abstract
An enhanced police Doppler direction sensing radar detects possibly dangerous traffic conditions during certain vehicle maneuvers such as U-turns and returns to travel after roadside stops. By monitoring a host or primary vehicle speed, speed transitions, transmission state (e.g. gear selection), and the closing vehicle position, range and speed, a number of selectable conditions are detected, resulting in an alert indication to a primary vehicle operator. User preferences and thresholds allow the traffic alert function to be customized according to a primary vehicle operator'"'"'s desire to suppress alerts in situations which the user does not deem dangerous. The traffic alert function may be automatically triggered under certain detected conditions, or manually initiated when the primary vehicle operator intends to make a driving maneuver.
