Abstract: A discriminating value approximately corresponding to the amount of a change in mean effective pressure is calculated on the basis of the revolution period of an internal combustion engine, and a cause for the vibration of the vehicle and conditions in driving on a rugged road are indirectly detected from a misfire-originated change in engine torque. The natural frequency of the suspension of the vehicle with the internal combustion engine mounted thereon is adjusted based on the result of the detection, thereby automatically preventing comfortable riding from being deteriorated by a misfire-originated change in torque or by a drive on a rugged road.

Abstract: A fail detecting system for an electromagnetic actuator avoids influence of a dither signal in detection of a failure of the electromagnetic actuator. Avoidance of influence of the dither signal is achieved by performing a comparison of a suspension control command with a driver current applied to the electromagnetic actuator in absence of the dither signal. An error value between the suspension control command and the driver current obtained through the comparison is compared with a predetermined fault detecting criterion for judging a failure of the electromagnetic actuator when the error value is greater than the fault detecting criterion.

Abstract: A suspension pressure control system on a vehicle applies a pressure which is proportional to a current level supplied to a solenoid of a pressure control valve to a shock absorber associated with respective one of suspensions from the valve. An electronic controller controls the current level to maintain an attitude of a vehicle substantially constant in spite of any change of longitudinal and lateral acceleration, which are detected by acceleration sensors. If a driver on the vehicle closes test indication switches TSW1 and TSW2, indicates "high" by a height indication switch HSW and rotates a steering wheel on the vehicle by B toward right, the vehicle laterally inclines such that a height of the left side of the vehicle rises up and a right side falls down responding to the rotation of the steering wheel. The inclination increases as the rotation of the steering wheel increases. The inclination decreases when the steering wheel rotates inverse direction toward the neutral position. When the steering wheel rotates beyond the neutral position toward left, the vehicle laterally inclines such that the height of the left side of the vehicle calls down and the right side rises up responding to the rotation of the steering wheel.

Abstract: A suspension control system includes a mechanism for monitoring wheel slippage on each of individual wheels as a parameter represenatative of road/tire traction. Suspension control is performed generally according to the vehicle driving conditions reflected in various suspension control parameters, such as vehicular speed, lateral acceleration and so forth in order to adjust spring coefficient or damping characteristics of a suspension system which is provided between a vehicle body and a suspension member supporting each individual wheel in order to adjust wheel load distribution and whereby to minimize variation of vehicular attitude change. Suspension control is further performed with taking the road/tire friction as one of suspension control parameters in order to provide traction dependent wheel load distribution.

Abstract: A fail-safe control unit for a vehicle having a first control system for controlling a steer angle and a second control system for controlling a condition of the vehicle, such as a driving force distribution in a 4WD system, or a damping characteristic of a suspension system. When one of the first and second control systems becomes abnormal, and the other remains normal, the fail-safe control unit adjusts the normal control system so as to maintain or improve the directional stability of the vehicle notwithstanding the failure of the abnormal system.

Abstract: A drive system of a piezo-type actuator for use in a motor vehicle, which piezo-type actuator is constructed with a piezoelectric device which is expandable and contractible in accordance with application of a voltage thereto. The drive system includes a voltage-increasing section for increasing an output voltage of a power source mounted on the motor vehicle so as to develop a drive voltage for the piezo-type actuator and a voltage-application section for applying to the piezoelectric device of the piezo-type actuator the drive voltage. Also included in the drive system is an abnormality detection section which is arranged so as to an abnormality of the drive voltage developed by the voltage-increasing section. A safety controller is responsive to an abnormality signal from the abnormality detection section for prohibiting the application of the drive voltage to the piezoelectric device thereof and further discharging charges accumulated in the piezoelectric device thereof when the abnormality detection section detects the abnormality of the developed drive voltage. With this arrangement, it is possible to prevent troubles due to the abnormality of the drive voltage to be applied to the piezoelectric device of the piezo-type actuator.

Abstract: A steering behavior dependent control system for controlling vehicular driving characteristics performs one or more control operations, such as anti-rolling suspension control, power assist control in a power steering system, rear wheel steering angle control in a four wheel steering system and so forth. The control system includes a steering angle sensor for monitoring steering angular displacement and produces a steering angle indicative signal. The control system is also provided a steering neutral position detector which detects steering at approximately a neutral position to produce an assumed steering neutral position indicative signal. A center value of a steering neutral range is projected on the basis of the steering angle indicative signal and the assumed steering neutral position indicative signal. Steering angle dependent control is thus performed by comparing the steering angle indicative signal value with the aforementioned center value to derive a magnitude of steering angular displacement. The control system further monitors an operating condition of the steering neutral position detector to detect a faulty condition thereof. When failure of the steering neutral position detector is detected, predetermined fail-safe operation takes place. In the fail-safe operation, the assumed center value of the steering neutral range is derived without utilizing the assumed steering neutral position indicative signal.
