The stress detecting sensor is disposed within the vehicle axle so as to detect at least one of a horizontal shear stress and a vertical sheer stress with the at least one strain gauge being one of aligned with or proximate the stress neutral line thereby permitting substantial removal of axle torque influence from an output of the stress detecting sensor. A signal processing circuit processes the output of the stress detecting sensor.

摘要： In an anti-lock brake system mounted on a vehicle wherein when the vehicle is braked in an emergency during running, an increase in the road surface friction force or road surface friction coefficient owing to an increase in the brake pressure is detected by a road surface friction force detecting device or road surface friction coefficient detecting device. The optimum control start point associated with an increase in the signal value of the road surface friction force F or road surface friction coefficient &mgr; provided by the road surface friction force detecting device or road surface friction coefficient detecting device is decided by using a decrease in the wheel speed, i.e., by using the wheel speed &ohgr; or d&ohgr;/dt. Thereafter, from the point where the specified value of control based on F or &mgr;, or dF/dt or d&mgr;/dt, the brake pressure is moved from the pressure increasing mode to the pressure retaining or decreasing mode.

摘要： A wheel-acting force measuring device permits accurate measurement of a shearing stress by removing a torsional stress component measured by a stress detector. A stress sensor includes four sensor segments which measure stress by a change in a characteristic thereof, arranged two on each of opposed surfaces of a base, preferably in cross form. The four sensor segments can be combined into various circuit configurations to produce a combined characteristic for each combination, each associated with a measurement of a particular stress acting on a wheel. In a preferred case, the four sensor segments are strain gauges, each which form part of a bridge circuit shiftably connected to allow the relative connection of each segment to be altered, thereby changing the configuration of the bridge. When in a first configuration, the output of the bridge circuit indicates primarily shearing strain mixed with a torsional strain component. When switched to a second switch position, the output of the bridge circuit indicates torsional stress. The torsional component may then be subtracted from the combined output measured when switched to the first position, yielding a value for the shear stress alone. The above may further be carried out using a logic bridge circuit arrangement to variably combine the segments. In a further embodiment, a plurality of stress sensors may be analyzed as above, the stress determined for each then extrapolated to yield a maximum value of shearing strain.
摘要翻译：车轮作用力测量装置允许通过去除由应力检测器测量的扭转应力分量来精确测量剪切应力。应力传感器包括四个传感器段，其通过其特性的变化来测量应力，该两个传感器段布置在基座的相对表面中的每一个上，优选为十字形。四个传感器段可以组合成各种电路配置，以产生每个组合的组合特性，每个组合都与作用在车轮上的特定应力的测量相关联。在优选的情况下，四个传感器段是应变计，每个传感器段形成桥接电路的一部分，桥接电路可移动地连接以允许每个段的相对连接被改变，从而改变桥的构造。当在第一配置中，桥接电路的输出主要表示与扭转应变分量混合的剪切应变。当切换到第二开关位置时，桥接电路的输出表示扭转应力。然后可以从切换到第一位置时测量的组合输出中减去扭转分量，产生单独的剪切应力值。可以使用逻辑桥电路装置进一步进行上述，以可变地组合这些段。在另一个实施例中，可以如上分析多个应力传感器，然后确定每个应力传感器的应力以产生剪切应变的最大值。
