摘要： An absolute position sensor having a low power mode includes a sensing device for sensing position of an object such as a power door, a power input for inputting power to the sensing device, and an output for supplying an output signal indicative of the sensed position. The sensor also includes a controller that receives the output signal and controls power supplied to the power input. The controller determines when the output signal does not change by a predetermined amount and controls the power input to reduce power when the output signal does not change by the predetermined amount. The controller further reapplies continuous full power to the power input when the output signal changes by the predetermined amount.

摘要： A technique for providing better detection of close range truck trailers for a motor vehicle with Stop and Go Adaptive Cruise Control determines if a range parameter to a target requires modification if such target is a truck trailer, for example. Truck trailer geometry is such that a standard adaptive cruise control system may have difficulty accurately determining the range to the rearmost position of the truck. The technique determines an initial range from the motor vehicle to a target. Then, the technique determines whether the range rate of the target is above a predetermined rate. When the range rate of the target is not above the predetermined rate, the technique determines whether the initial range to the target is less than a current range to the target. If so, the technique provides an adjusted range, which is then utilized in the control operation of the motor vehicle.

摘要： An electronic position sensor for use with a power operated vehicle accessory, such as a power liftgate. The position sensor includes an elongated resistive circuit that is mounted such that it is stationary and extends along the path of a track portion of the power operated accessory. The position sensor further includes a contact nub mounted to a link member that moves within the track portion such that the contact nub is slidingly biased against the elongated circuit. As the link member moves under the force of a motor-driven output gear, the contact nub slides along the surface of the resistive circuit, thereby affecting the overall resistance of the circuit. The position sensor uses the overall resistance to provide an electronic position signal to an ECU, wherein the signal is indicative of the absolute position of the power operated accessory. Accordingly, the electronic position sensor is capable of providing an electronic signal that enables the ECU to track the absolute position of the power operated accessory.
