Abstract: A modular suspension strut apparatus provides a bicycle with a relocatable center of gravity to adjust the bicycle to the rider and to terrain conditions. The combined center of gravity of a bicycle and rider is adjustable by moving and clamping a strut within a strut tube. A crank axle housing at the bottom of the strut and a seat post at the top are shifted vertically, while maintaining a fixed seat axle distance. The strut is resiliently mounted within the strut tube by an internal or external spring or springs to absorb shocks. Spring force is adjusted by adjusting an air pressure with an external air pump or on board pumps. Spring forces may be adjusted while seated or in motion by turning knobs or handwheel rings and/or by other means. Strut movement within the strut tube is limited to axial reciprocation in a preset range. Elastomeric rings prevent shock at limits of the strut movements. The strut tube is made of three joined parts, a center tube and top and base guides.

Abstract: A vehicle steering apparatus includes a variable gear ratio mechanism which is provided in a steering force transmitting system, and a lock mechanism which restricts relative rotation of an input shaft and an output shaft of the transmitting ratio changing mechanism. The lock mechanism is engaged by inserting a lock arm in a indented portion of a lock holder of the lock mechanism. A play angle when the lock mechanism is engaged by inserting the lock arm in the indented portion is set to be smaller than a rotational angle of a motor which is required for outputting six different signals.

Abstract: A torque detector that suppresses fluctuation of an output value relative to fluctuation of an input value and that also has the output value accurately follow the input value even when the input value changes suddenly. The torque detector includes a detection element, a converter, and a hysteresis processor. The detection element detects the steering torque applied to a steering shaft when the steering shaft is rotated to generate an analog torque signal corresponding to the steering torque. The converter converts the analog torque signal to a digital torque signal. The hysteresis processor performs hysteresis processing on the digital torque signal to include the value of the digital torque signal in a predetermined range.

Abstract: A traction control system (TCS) in which the engine torque is reduced after a slip threshold has been exceeded by at least one driven wheel and is raised again after the slip has fallen below the threshold, the traction control system further including an arrangement for detecting cornering and coefficient of friction. In order to improve vehicle stability when cornering, upon detection of cornering on a road surface having a low coefficient of friction, the gradient of the engine torque increase during the TCS control action is set lower than when traveling straight ahead.

Abstract: A method for implementing directional control of a motor vehicle is disclosed. In an exemplary embodiment, the method includes determining whether a failure of a primary steering system of the motor vehicle exists. If a failure of the primary steering system exists, then a yaw moment is created on the vehicle by causing a differential longitudinal force to be applied with respect to a first wheel on one side of the vehicle and a second wheel on an opposite side of the vehicle, thereby causing the vehicle to turn in a commanded direction.
