摘要： A damping control device for a vehicle calculates a combined control force by adding together a control force when a front wheel passes through a predicted passing position and a control force when a rear wheel passes through a predicted passing position, and calculates a final control force for the front wheel and a final control force for the rear wheel by distributing the combined control force at a predetermined distribution ratio.

摘要： An apparatus for determining the center position of a steering system installed in a vehicle uses a distance based algorithm to correct the center position. The actual steering position is sampled periodically, based upon the distance traveled by the vehicle, and corrections are made according to the difference between the sampled positions and a previously assumed steering center.

摘要： Systems, computer-implemented methods, and computer program products relating to jerk of a vehicle damper are provided. According to an embodiment, a system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise a control signal determination component that determines movement of a front damper of a vehicle, an amount of time between a first time when the movement of the front damper occurs and a second time when a rear damper of the vehicle will experience a condition which caused the movement of the front damper, and a front damping coefficient of the front damper, and determines a rear damping coefficient of the rear damper configured to mitigate rear suspension impact with an end stop caused by rear suspension compression or rebound based on the movement of the front damper, the amount of time, and the front damping coefficient, and a damper adjustment component that adjusts the rear damper to the rear damping coefficient.

摘要： A method and apparatus for determining a center position of the vehicular steering system includes a steering sensor and a control unit. A variable threshold time strategy is employed with a fixed window of operation and a movable window of operation to determine a precise center for the steering system. As an option, the control algorithm may employ both a variable theshold time and a variable size for the movable window of operation.

摘要： The present invention relates to a method for controlling a suspension system of a motor vehicle comprising a vehicle body and a plurality of wheel pairs (2a/2b, 2c/2d), wherein the suspension system comprises spring members arranged for resilient connection between the wheels of the vehicle and said vehicle body. The method comprises the step of: monitoring at least one first parameter indicating braking of thee motor vehicle, and when said parameter indicates braking of the motor vehicle, preventing compression of the spring members of at least one wheel pair (2a/2b, 2c/2d) of the motor vehicle for counteracting a rotation of the vehicle body in connection to braking.

摘要： The present invention provides, with reference to the figure, a vehicle suspension system comprising an actuator (10) connected between the body (17) of a vehicle and a wheel and hub assembly (18) of the vehicle. A source of pressurized fluid (20) and an exhaust for fluid (24) are provided along with a valve (22) for controlling flow of fluid to the actuator (10) from the source of pressurized fluid (20) and/or from the actuator (10) to the exhaust for fluid (24). A sensor (27, 28, 30, 31, 32, 33, 34, 35, 41) is used to generate signals of sensed variable vehicle parameters. A control system for the vehicle suspension system is used which has a processor (25, 20) which processes the signals generated by the sensor (27, 28, 30, 31, 32, 33, 34, 35, 41). The processor (25, 26) outputs a control signal to the valve (22) and thereby controls the actuator (10). The processor in normal operating conditions uses a first set of preprogrammed constants (e.g. control loop gains, integrating factors, desired ride heights) in algorithms used by the processor to calculate the control signal outputted thereby. The processor uses a different set of preprogrammed constants in the algorithms for a chosen time period following activation of the system and/or at low vehicle speeds and/or a low pressure of fluid supplied by the source of pressurized fluid (20).
