    • An anti-skid braking system for a vehicle, having (a) hydraulic brakes for wheels of the vehicle, (b) actuators provided for respective brake groups each including at least one of the brakes, for controlling a braking pressure or pressures of the brake or brakes of the corresponding groups, (c) speed sensors, at least one of which is provided corresponding to each actuator, for detecting speeds of the wheels, and (d) to controller operable for: normally presuming that an actual speed of the vehicle is represented by a highest one of the detected wheel speeds; after a deceleration value of the highest speed has exceeded a preset upper limit, fixing the deceleration value of the vehicle at the preset upper limit, and presuming the actual vehicle speed based on the upper limit; and calculating a slip amount of each wheel based on a difference between the presumed vehicle speed and the detected wheel speed, to control each actuator so as to prevent the wheel from skidding. The system includes a detector generating a signal whose level is changed in at least two steps indicative of at least two values of an actual deceleration value of the vehicle. The system further includes a setting device for determining the upper limit of the deceleration value such that the upper limit is changed with the detected actual deceleration value.

    • An anti-skid braking system for a four-wheel drive vehicle in which all of the four wheels are driven by a single drive source and are connected to each other by front and rear pairs of axles connected by a propeller shaft, and a differential disposed on at least one of the front and rear pairs of axles. The braking system includes an actuator for controlling mutually independently the braking pressures of at least one pair of left and right wheels connected to the axles between which the differential is disposed, and further includes a controller for controlling the actuator so as to maintain the slip ratios of the left and right wheels within an optimum range, thereby preventing skidding of the wheels on a road surface upon brake application. The controller determines for each of the left and right wheels, whether the braking pressure must be increased or decreased, and commands the actuator, upon determination of simultaneous increases and/or simultaneous decreases of the braking pressures of both of the left and right wheels, such that the braking pressure of one of the left and right wheels is controlled in a normal manner as determined by the controller, while the braking pressure in the other of the left and right wheels is controlled in an override manner different from the normal manner.
    • 一种用于四轮驱动车辆的防滑制动系统,其中所有四个车轮由单个驱动源驱动,并且通过由推进器轴连接的前后对成对的轴彼此连接,并且差速器被设置 在前轴和后轴对中的至少一个上。 制动系统包括用于相互独立地控制连接到其间布置有差速器的轴的至少一对左右轮的制动压力的致动器,并且还包括用于控制致动器以便保持滑动比的控制器 左右车轮在最佳范围内,从而防止制动器施加时车轮在路面上滑动。 控制器为左右车轮中的每一个确定制动压力是否必须增加或减小,并且在确定左右两车轮的制动压力同时增加和/或同时降低时,命令致动器, 使得左右一个车轮的制动压力以由控制器确定的正常方式进行控制,而左右车轮中的另一个的制动压力以与正常方式不同的超控方式进行控制。

    • An anti-skid control system for use in a motor vehicle having wheels whose rotational speeds are sensed by wheel sensors. The anti-skid control system decides the condition of the road-surface, on which the motor vehicle is running, on the basis of signals from wheel sensors. A reference speed is further calculated on the basis of the sensed speeds of the wheels symmetrically provided at the rear-right and rear-left sides with respect to the advancing direction of the motor vehicle. That is a selected one of an average value of the speeds of the rear-right and rear-left wheels sensed by the wheel sensors and the maximum one of the sensed rear-right and rear-left wheel speeds is selected in accordance with the decided road-surface condition. The reference speed is calculated on the basis of the selected one. A control unit of the anti-skid control system performs slip control of the wheels in accordance with the calculated reference speed. With this arrangement, the anti-skid control system can improve the braking efficiency and controllability irrespective of turning of the motor vehicle.
    • 一种用于机动车辆的防滑控制系统,其具有通过车轮传感器检测其转速的车轮。 防滑控制系统基于来自车轮传感器的信号来确定机动车辆正在行驶的路面的状况。 基于相对于机动车辆的前进方向在右后侧和左后侧对称设置的车轮的感测速度进一步计算基准速度。 这是由车轮传感器感测到的后右后轮和左后轮的速度的平均值中选择的一个,并且根据所确定的选择感测到的右后轮和后轮的最大速度的最大值 路面状况 基于所选择的参考速度计算。 防滑控制系统的控制单元根据计算出的基准速度来执行车轮的滑动控制。 利用这种布置,防滑控制系统可以改善制动效率和可控制性,而与机动车辆的转动无关。
