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.

A haptic braking method and system is disclosed. A controller operates a pump to apply brake fluid to a brake when it is necessary to decelerate a wheel during an active cruise control mode of a vehicle. The controller further operates one or more valves to cyclically vary a pressure level of the brake fluid to cause one or more haptic movements of the brake.

A stop determination for a vehicle is provided by requiring simultaneous stop determinations by at least one wheel speed sensor providing output pulses at a rate inversely proportional to vehicle speed and a forward looking radar unit for sensing an object in the vehicle's path and providing a range rate signal with respect to that object. The determination is particularly useful when the time between consecutive pulses at a predetermined minimum speed indicative of an essentially stopped vehicle is greater than a predetermined maximum time period allowed for the determination. Each of the signals complements the other to provide a vehicle stopped determination that is more reliable than either can provide by itself and is workable for most purposes, including stop and go vehicle speed control.
