Vehicle collision warning system and method
First Claim
Patent Images
1. A vehicle collision warning system provided in a vehicle, comprising:
- a first sensor monitoring a rear-center area of the vehicle;
a second sensor monitoring rear-lateral-corner areas of the vehicle;
an operator alarm configured to selectively provide an alert to an operator of the vehicle; and
a collision warning electronic control unit comprising;
a rear-center area impending collision detection module configured to detect a rear-center area impending collision based on an input from the first sensor;
a rear-lateral-corner area impending collision detection module configured to detect a rear-lateral-corner area impending collision based on an input from the second sensor; and
an alarm control module configured to control the operator alarm in one of a standard mode and a towing mode,whereinin the standard mode, the alarm control module controls the operator alarm to provide the alert to the operator when the rear-center area impending collision is detected by the rear-center area impending collision detection module and/or the rear-lateral-corner area impending collision is detected by the rear-lateral-corner area impending collision detection module, andin the towing mode, the alarm control module controls the operator alarm to provide the alert to the operator when the rear-lateral-corner area impending collision is detected by the rear-lateral-corner area impending collision detection module, and to provide no alert to the operator when the rear-center impending collision is detected by the rear-center area impending collision detection module.

Abstract
A vehicle collision warning system and method detects a rear-center area impending collision and a rear-lateral-corner area impending collision, and controls an operator alarm in one of a standard mode and a towing mode. In the standard mode, the operator alarm is controlled to provide an alert to an operator when the rear-center area impending collision is detected and/or the rear-lateral-corner area impending collision is detected. In the towing mode, the operator alarm is controlled to provide the alert to the operator when the rear-lateral-corner area impending collision is detected by the rear-lateral-corner area impending collision detection module, and to provide no alert to the operator when the rear-center impending collision is detected by the rear-center area impending collision detection module.

20. A method of controlling a vehicle collision warning system, comprising:
-
detecting a rear-center area impending collision and a rear-lateral-corner area impending collision; determining whether a vehicle is operating in a standard mode or a towing mode; when the vehicle is determined to be operating in the standard mode, controlling an operator alarm to provide an alert to an operator when the rear-center area impending collision is detected and/or the rear-lateral-corner area impending collision is detected, and when the vehicle is determined to be operating in the towing mode, controlling the operator alarm to provide the alert to the operator when the rear-lateral-corner area impending collision is detected and to provide no alert to the operator when the rear-center area impending collision is detected.
