摘要： A method is disclosed for controlling a backing maneuver of an automotive vehicle and trailer combination in which the vehicle has operator-actuated front wheel steering and microprocessor-actuated, reversible electric motor driven rear wheel steering. For a given initial alignment of vehicle and trailer, the computer-executed method first determines whether the driver needs to pull forward before commencing the backing operation. The driver is then requested to turn the front wheels in a direction suitable for backing the vehicle without a trailer in the desired direction. The process then determines whether the driver needs to perform counter front wheel steering before backing. Then the process controls the steering of the rear wheels during the backing operation.

摘要： A damper assembly is provided including a linear to rotary motion conversion mechanism having an outer tube member. An inner tube member is reciprocally movable and at least partially disposed within the outer tube member. The inner tube member is adapted for linear translation in a first and a second direction. A rotatable shaft is disposed within the inner tube member. The translation of the inner tube member produces a rotation of the shaft. Also included within the damper assembly is a damping mechanism having a rotor fixed to the shaft. A coil is configured to generate an electromagnetic field in response to an applied current. A magneto-rheological fluid is in contact with the rotor, and has a variable viscosity in the presence of the electromagnetic field that, in turn, provides variable resistance to rotation of the rotor and translation of the inner tube member within the outer tube member.

摘要： An improved magnetorheological fluid damper is provided which closely approximates ideal performance requirements by providing an increased turn-up ratio and improving the linearity of damping force response. The MR damper includes a plurality of concentric annular flow gaps formed between concentrically mounted flux rings positioned on a piston core. By utilizing multiple flow gaps, the present damper increases the overall magnetorheological damping affect thereby creating a higher damping force and an increased tun-up ratio for a given piston size. Alternatively, the present multiple flow gap design permits a given damping force requirement to be achieved with a piston having a significantly reduced length thereby permitting a longer piston stroke. Also, multiple flow gaps permit greater design optimization for controlling damping force linearity.
