Abstract
A system for barrier proximity detection, comprising a short-range detection (SRD) sensor, a barrier proximity detection system (BPDS) controller, and an operator display and control. The SRD sensor mounted on the vehicle detects the distance to objects and transmits a distance signal to the BPDS controller. The BPDS controller provides an operator control signal to the operator display and control for the driver's use. The BPDS controller may also store preset alarms, distance setpoints, or desired ranges for repeated use. The operator display and control may be a gradient alert display with audible alarms or an alphanumeric display to indicate the distance to an object with a preset target distance. The method provides the steps of measuring a desired range between the front of a vehicle and a barrier and storing the desired range in the BPDS, then using the desired range to provide a clear indication to the driver.
