    摘要： Disclosed is a control apparatus for a vehicular suspension system having a plurality of suspension units each disposed between a road wheel and the body of a vehicle for suspending the corresponding road wheel from the vehicle body. The control apparatus includes a control unit which is connected to receive the output signals from an acceleration sensor, a vehicle-speed sensor and a steering sensor for calculating the rolling state of the vehicle due to a transverse acceleration thereof and controlling the respective suspension units based on the calculated rolling state of the vehicle so as to suppress the rolling thereof. The control apparatus further includes a drift compensator for compensating for a drift of a neutral point of the output signal of the acceleration sensor based on the output signals from the acceleration sensor, the vehicle-speed sensor and the steering sensor signal of the acceleration sensor based on the output signals from the acceleration sensor, the vehicle-speed sensor and the steering sensor.

    摘要： A suspension control device including a control device for variably controlling a damping force of a suspension to an optimum value by determining a magnitude of acceleration is vertical opposite directions of a vehicle body which magnitude is equal to or greater than a predetermined level and measuring the accumulated duration time of a sprung resonance which is detected by a cycle of vibration of the vehicle body from a timing of the determination of the magnitude. In another aspect, the suspension control device includes a control device for outputting a command for increasing a damping force when a magnitude of acceleration in vertical opposite directions of a vehicle body is determined to be equal to or greater than a predetermined level, and measuring the number of repetitions of a sprung resonance which is detected by measuring a cycle of vibration of the vehicle body from a timing of the determination of the magnitude. The control device maintains the damping force at a high level until the vehicle is stopped and a door open condition is detected.

    摘要： A control apparatus for a motor-driven power steering system of a motor vehicle controls the steering system such that a steering torque required to be applied by a driver is prevented from increasing abruptly or steeply even when generation of an assist torque applied to the steering system for assisting the driver in steering operation is to be stopped. The control apparatus includes an operation stop decision mechanism (111, 112, OR) for deciding whether or not an operation stop command is to be issued for stopping control operation for the motor-driven power steering system, a torque detecting mechanism (16, 113) for detecting a steering torque transmitted from an input shaft (21a) to an output shaft (21c) of a steering column (21) of the motor-driven power steering system, and an assist torque control mechanism (114, 116, 117, 118, 13) for updating an assist torque applied by an electric motor (20) to the output shaft (21c) with an assist torque control quantity determined on the basis of a detected torque value outputted from the torque detection mechanism (16, 113), wherein upon issuance of the operation stop command by the operation stop decision mechanism (111, 112, OR), the assist torque control mechanism stops application of the assist torque, provided that the detected torque value is lower than a predetermined value inclusive thereof.
