摘要： A method of determining a vehicle steering wheel angle by receiving at least one steering sensor output from at least one steering sensor. The method then receives a vehicle speed signal. A centered steering angle is determined based on the received vehicle speed signal and the steering sensor output.

摘要： A sealing apparatus for a vehicle closure, such as a door, includes a vacuum system for deflating the vehicle weatherstrips or sealing members. A plurality of deflatable sealing members may be connected to a single vacuum source. The system includes a sensor/actuator for detecting motion of the individual vehicle closures and a flow control circuit including valve arrangements for selectively connecting a particular sealing member to the vacuum source. In response to detected closing motion of a particular closure, the sealing member associated with that closure is deflated to allow the closure to close and latch with relatively low effort. Once closed, the sealing member is vented to atmosphere and reexpands by resilient memory to full cross-section thereby providing a relatively tight interference seal. The closure motion sensor/actuator includes a flexible strip having a series of aligned, closely spaced apertures and a cooperating pawl and actuator lever for operating the valves.

摘要： A vehicle has a real time suspension control which requires, as inputs, a set of absolute body modal velocity signals. Accurate estimates of these signals are derived from relative position sensors at the body suspension points by converting the relative vertical position signals from these sensors to relative body modal (e.g. heave, pitch and roll) velocity signals and passing each of these signals through a second order low pass filter including an additional phase inversion for compensation of the 180 degree filter phase lag. Thus, the necessity of absolute body accelerometers is eliminated, for a significant cost reduction. In a vehicle having significant front to rear flexing or flexing within the front or rear suspension that can affect the accuracy of the estimated absolute body roll velocity, the normal roll velocity transformation equation is modified to include only the front or the rear pair of relative velocity signals.
