摘要： A suspension and steering control system includes a mode selection which enables a normal mode wherein the suspension is conditioned to produce a soft damping and sufficient power assistance to the steering to produce light steering characteristics and a sporty mode wherein the suspension is conditioned to produce a firm ride and the power assistance to the steering lowered to produce heavier steering characteritics. The system further includes an arrangement for sensing parameters which are related to the attitude of the vehicle and/or the suspension thereof and for (a) during the normal mode, temporarily conditioning the suspension to produce the firm ride characteristics if the attitude of the vehicle is apt to change beyond a predetermined amount, and for (b), during the sporty mode, temporarily conditioning the suspension to produce the soft ride in the event that no substantial changes in the vehicle attitude related parameters are sensed.

摘要： A vehicular height control system includes means for detecting road roughness condition on the basis of a vehicular height indicative signal which is produced by a vehicular height sensor. The control system also includes means for detecting the road roughness condition satisfying a predetermined condition for disabling vehicular height control. Disabling of vehicular height control keeps the control system free from fluctuation of vehicular height indicative signal value due to uneveness of the road surface.

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 electronically controlled power steering system comprises a vehicle speed sensor, a steering wheel angle sensor, a power steering gear including a control valve, a bypass valve for regulating a flow rate of hydraulic fluid supplied to the control valve of the power steering gear in response to a control signal generated by a controller. The controller is operative responsive to sensor output signals of the sensors for generating the control signal. With the controller, the control signal is varied in response to the vehicle speed and the steering wheel angle when the steering wheel angle is less than a predetermined value, but this varying tendency of the control signal in response to the steering wheel angle is restrained when the steering wheel angle is not less than the predetermined value.

摘要： A tire exhibiting a desired design performance can be manufactured at a low cost using a precured tread having a mounting surface formed flat. In the process of manufacture, a base tire formed with a tread mounting surface having curvatures in the axial and circumferential directions of the tire and a precured tread having amounting surface formed flat, which is to be applied to the tread mounting surface of the base tire, are used. The precured tread has grooves (9) in its tread pattern surface opposite from its mounting surface. And the circumferential and axial lengths of the grooves (9) are formed shorter than desired design values, based on the differences in the circumferential and axial lengths between when the mounting surface of the tread applied to the base tire is curved along the curvatures of the tread mounting surface of the base tire and when the mounting surface of the tread is in a flat state.
