摘要： A suspension control system employs a road sensor monitoring road roughness or smoothness and producing a road condition indicative signal. The control system also employs other sensor or sensors for monitoring at least one preselected suspension control parameter, such as vehicle speed, steering angular variation and so forth, other than road roughness. The suspension switches between relatively hard and relatively soft characteristics based on the preselected suspension control prameters. In order to make suspension control more precisely suited to the vehicle driving conditions, the control characateristics of the suspension system are adjusted depending upon the road condition. With this arrangement, even when the suspension is controlled so as to suppress vehicular roll based on the steering angular displacement and when rough road conditions cause steering angular displacement due to kick-back from the road input through the steering mechanism, the erroneous judgement that steering adjustments are about to cause vehicular roll can be avoided. In case of acceleration responsive suspension control, rough road conditions tend to cause a driver to unconsciously operate the accelerator pedal so as to increase and decrease throttle valve angular position relative to the fully closed position. According to the present invention, by adjusting the control characteristics, erroneous detection that the vehicle is accelerating, which would normally cause winding-up, can be successfully avoided.
摘要翻译：悬架控制系统采用道路传感器监测道路粗糙度或平滑度并产生道路状况指示信号。控制系统还采用其它传感器或传感器用于监测道路粗糙度以外的至少一个预选悬架控制参数，例如车辆速度，转向角度变化等。基于预选的悬架控制参数，悬架在相对较硬和相对较软的特性之间切换。为了更准确地适应车辆行驶条件的悬架控制，根据道路状况来调整悬架系统的控制特性。由此，即使在基于转向角位移来控制悬架来抑制车辆滚动的情况下，当路面状况恶劣导致由于通过转向机构输入的道路而引起的转向角位移时，转向调整即将导致车辆滚动可以避免。在加速响应悬架控制的情况下，恶劣的道路状况倾向于导致驾驶员无意识地操作加速器踏板，以便相对于完全关闭位置增加和减少节气门角位置。根据本发明，通过调整控制特性，可以成功地避免车辆正在加速的错误检测，这通常会导致卷起。

摘要： An anti-squat suspension control system includes an anti-squat control disabling means for disabling anti-squat control for a period while an engine idling condition detector switch is held closed or a given period after the engine idling condition detector switch is switched from closed position to open position. The system also includes fail detector means for monitoring operation of the engine idling condition detector switch to detect failure of the switch. When the failure of the engine idling condition detector switch is detected, the anti-squat disabling means is disabled.

摘要： An ultrasonic air spring system adapted to be mounted on a vehicle for absorbing road shocks exerted on the vehicle and for maintaining the vehicle body level with respect to the axles. An air spring includes an end plate and a piston sealingly connected to the open ends of the flexible elastomeric sleeve to form a pressurized fluid chamber therebetween. A transducer is mounted on the end plate within the fluid chamber and transmits ultrasonic signals through the fluid chamber toward the piston and picks up reflected signals therefrom. A signal is generated by the transducer in response to the reflected signals and fed to a microprocessor based control module. The control module determines whether the air requires fluid feed or exhaustion and will then implement control of inlet or exhaust valves to achieve a desired axial separation between the end plate and piston.

摘要： Disclosed is a method for measuring height in a vehicle by determining a distance between a vehicle chassis and a vehicle axle or parts connected thereto. In the method, a first device (12) with a first transmitter (13) and a first receiver (14) and a second device (15) with a second transmitter (16) and a second receiver (17) interact. In particular, the first transmitter (13) produces an electromagnetic field, and the second receiver (17) detects the electromagnetic field. The second device (15) with the second transmitter (16) produces a signal from the detected field and transmits the signal, which correlates with the distance from the first transmitter (13) to the second receiver (17). The first device (12) with the first receiver (14) receives the signal. A system, an electronically controlled pneumatic suspension, an electronic control unit, and a vehicle are also disclosed.

摘要： A vehicle tire load sensing system includes distance sensors mounted on the vehicle near each tire. The distance sensors generate distance signals representing a distance from the sensor to a track that is left in the soil during forward vehicle travel. Pressure sensors generate tire pressure signals. A temperature sensor senses the ambient temperature. A control unit receives the distance signals, the pressure signals and the temperature signals. The control unit compensates the distance signals as a function of the sensed temperature. The control unit generates filtered distance signals, and determines a tire deflection value from the filtered distance signal. The control unit determines the tire load as a function of the tire deflection value, the pressure signal and stored information relating tire load to tire deflection and tire pressure.
