摘要： An apparatus for controlling steer angle of rear wheels of a 4-wheel steering vehicle in accordance with the operation of a steering wheel for generating steer angle of front wheels. The apparatus comprises a first member which moves in response to the operation of the steering wheel; a second member which moves in response to the operation of the steering wheel in a direction counter to that of the first member; an output shaft for controlling the steer of the rear wheels; a resilient member disposed between the first member and the output shaft and a controller disposed between the second member and the output shaft for controlling the direction of movement of the output shaft in accordance with the speed of operation of the steering wheel. When the steering wheel is operated at high speed, the resilient member absorbs the force from the first member so that the output shaft moves in the same direction as the second member, whereby the rear wheels are turned in a direction counter to that of the front wheels. When the steering wheel is operated at low speed, the force from the second member is damped so that the output shaft moves in the same direction as the first member, whereby the rear wheels are turned in the same direction as the front wheels.

摘要： A rear wheel steer angle controlling apparatus for vehicles having steerable front and rear wheels, adapted for controlling the steer angle of rear wheels in response to the operation of the steering wheel for steering the front wheels. When the steering wheel is operated quickly, a rear wheel steer angle is formed in the counter direction to the direction of the front wheel steer angle, so that the response to the steering input for turning the vehicle is improved. Conversely, when the steering wheel is operated slowly, a rear wheel steer angle is formed in the same direction as the front wheel steer angle, thus enhancing the stability of the vehicle running straight. When the vehicle is running at a high speed, the rear wheel steer angle is formed always in the same direction as the front wheel steer angle regardless of the speed of operation of the steering wheel, so that the steering stability during high speed running is improved. When a yawing moment is generated due to a disturbance such as lateral wind, the rear wheel steer angle is automatically controlled in such a manner as to negate the yawing moment, thus compensating for the lateral displacement of the vehicle without requiring correcting steering operation by the driver.
摘要翻译： 一种用于车辆的后轮转向角度控制装置，其具有可转向的前轮和后轮，适于响应于用于转向前轮的方向盘的操作来控制后轮的转向角。 当方向盘快速操作时，在与前轮转向角方向相反的方向上形成后轮转向角，从而提高了对转向车辆的转向输入的响应。 相反，当方向盘操作缓慢时，后轮转向角度形成在与前轮转向角相同的方向上，从而提高了直线行驶的稳定性。 当车辆高速行驶时，无论方向盘的操作速度如何，后轮转向角度始终与前轮转向角度相同的方向形成，从而提高高速行驶中的操纵稳定性 。 当由于诸如横向风等干扰而产生偏航力矩时，后轮转向角度被自动地控制，从而抵消偏转力矩，从而补偿车辆的横向位移，而不需要修正车辆的转向操作 司机。

摘要： A tire uniformity measuring apparatus having: a drum for rotating a tire; an oscillating member disposed parallel to a drum rotating shaft and pivotally supported on a machine base through a fulcrum; a movable member disposed in parallel to the drum rotating shaft in the plane including the drum rotating shaft and a tire rotating shaft, the movable member being laterally movable in response to a load acting on the tire in a lateral direction perpendicular to the radial direction of the tire; a load applying member for applying in advance a predetermined load to the tire; and a displacement detecting member for detecting as a displacement of the movable member the displacement of the tire rotating shaft which is dependent on variation in the lateral load; thereby detecting a variation in the lateral load of the tire. The apparatus may comprise a further movable member which is a shaft member constituting the fulcrum, the movable member being slidably movable along the longitudinal axis only in response to a variation in the tangential load, and a further displacement detecting member for detecting a displacement of the movable member, thereby detecting a variation in the tangential load acting on the tire.

摘要： A braking force control device is provided in which wheel speeds of respective wheels of a vehicle are detected. On the basis of detected wheel speeds, a road surface &mgr; slope, which is a slope of a coefficient of friction &mgr; between a wheel and a road surface, is estimated for each wheel. On the basis of the road surface &mgr; slope estimated for each wheel, a braking force of each wheel is controlled such that the braking force of each wheel is adjusted.
