摘要： Methods and devices for measuring and calculating wheel alignment angles. Light weight and mechanically robust accelerometers in measurement heads are attached to a vehicle's wheels during an alignment procedure. The output of the accelerometers may be compensated for effects of temperature or thermal hysteresis by memory lookup or a temperature based feedback control loop.

摘要： A wheel alignment adjusting device in which adjustment of a toe angle can be effected accurately, precisely, easily, and in a short time. A wire is anchored to a supporting frame at which an endless track is provided. An intermediate portion of the wire is trained around a pulley of a rotary encoder. A rotational angle of the supporting frame is transmitted to the rotary encoder with the rotational angle magnified. Accordingly, a minute angle can be measured accurately.

摘要： The intention is to specify a simplified design for a device which is used in vehicles for determining a vertical distance between a vehicle body and at least one vehicle wheel which is adjustably mounted thereon. In the device according to the invention, a first inclination sensor which generates first inclination signals which are correlated to the inclination of the vehicle body with respect to a reference position, and transmits them to a control unit, is attached to the vehicle body. Attached to a coupling component which is adjusted, together with the vehicle wheel, relative to the vehicle body, is a second inclination sensor which generates second inclination signals which are correlated to the inclination of this coupling component with respect to a reference position, and transmits them to the control unit. The control unit then determines from the inclination signals of the inclination sensors a distance signal which is correlated to the vertical distance between the vehicle wheel and the vehicle body.

摘要： A diagnosing apparatus and method for determining an occurrence of failure in a rear road wheel steering angle sensor of a motor-driven four wheel steering system of an automotive vehicle which can achieve a highly accurate detection of the occurrence of failure in the single rear road wheel steering angle sensor at an appropriate timing irrespective of a sensor failure mode. The detection of failure in the rear road wheel steering angle sensor is carried out on the basis of whether a target deviation between a rear road wheel steering angle sensor value and a target rear road wheel steering angle exceeds a predetermined deviation value and whether a generation time duration during which the target deviation exceeds the predetermined deviation value has continued over a predetermined period of time. In addition, the detection of failure in the rear road wheel steering angle sensor is carried out on the basis of whether an accumulated value of a rear road wheel steering angle estimated deviation .intg..DELTA..delta.# exceeds a predetermined threshold value a when such conditions as a monotonous variation in a servo current applied to the motor in the four wheel steering system, a monotonous variation in a rear road wheel steering angle estimated deviation, and same directional monotonous variations in the servo current and in the rear road wheel steering angle estimated deviation are satisfied.

摘要： Vehicle wheel alignment apparatus includes a storage device for storing vehicle wheel alignment angle specifications, wheel alignment sensors, and ride height sensors. A controller is responsive to the acquired wheel alignment angle data and to the measured ride height for determining whether, taking into consideration the vehicle ride height, a measured wheel alignment angle falls within specifications. Apparatus for diagnosing vehicle wheel alignment and suspension problems also includes a jack for vertically moving the body of the vehicle with respect to the wheels to temporarily change the ride height of the vehicle. The controller is responsive to changes in measured wheel alignment angles with changes in measured ride height to diagnose vehicle alignment and suspension problems.

摘要： A method of measuring and adjusting the wheel alignment of an automotive vehicle comprises bringing all of the four tires in condition for actual on-road running performance, restricting axial movement of both of the front tires alone, measuring the toe-in angles of the front and rear tires and adjusting the toe-in angle of each of the rear tires to the specification whereby the center line of an alignment adjusting apparatus is brought into alignment or parallel relation to the center line or axis of the vehicle. An apparatus is also disclosed for reducing this method to practice.

摘要： A roller clamp type wheel examining apparatus includes a support for supporting thereon a wheel of a vehicle to be examined, a plurality of rollers for clamping the wheel supported on the support from both sides thereof and an angle detector for detecting the angle of orientation of the wheel when clamped by the plurality of rollers. The wheel of a vehicle clamped by the rollers on both sides thereof may be driven to rotate around its own rotating axis to thereby examine dynamic characteristics of the wheel. In this case, the support structure should, for example, include a pair of support rollers for supporting thereon the wheel to be examined in a rotatable manner. The support may include a floating table having a flat top support surface and movable in a horizontal plane translationally as well as rotationally, in which case only the dynamic characteristics of the wheel may be examined since the wheel is not rotatable around its rotating axis.
