摘要： A braking system including a hydraulically operated brake for braking a drive wheel of a motor vehicle, a slip detector for detecting an amount of slip of the drive wheel, and a pressure-regulating controller for increasing or decreasing a fluid pressure to be applied to the brake, in response to each output signal of the slip detector, whose value indicated a pressure-increase or pressure-decrease condition which requires an increase or decrease in the fluid pressure, respectively, such that the amount of slip of the drive wheel is maintained within an optimum range. The braking system incorporates a device for commanding the pressure-regulating controller to delay commencement to increase and/or decrease the fluid pressure to be applied to the brake, with respect to a part of the occurrences of the pressure-increase condition and/or the pressure-decrease condition, for a predetermined time duration as measured from a point of time at which the pressure-increase and/or said pressure-decrease condition is/are established.

摘要： 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.

摘要： The anti-skid control system is capable of performing highly reliable anti-skid control through its accurate estimation of the vehicle speed and proper compensatory control even when sharp braking occurs or in the brake fluid pressure control on road surfaces with a low coefficient of friction likely to cause considerable fluctuations in wheel acceleration. The anti-skid control system is provided with a fluid pressure generating device, a fluid pressure controlling device, a wheel velocity detecting device, a standard speed setting device, a fluid pressure controlling mode setting device which sets either the pressure decrease mode or the pressure hold mode when the wheel velocity declines to a level lower than the standard speed and sets the pressure increase mode when the wheel velocity is equal to or higher than the standard speed. A maximum inflection point detecting device detects the maximum inflection point indicating the maximum value for the shift of the wheel velocity mentioned above from an increase to a decrease when the wheel velocity is not any lower than the standard speed. A fluid pressure controlling mode correcting device switches from the pressure increase mode mentioned above to either the pressure hold mode or the pressure decrease mode when the wheel velocity becomes equal to or higher than the standard speed and also becomes equal to or higher than the wheel velocity at the maximum inflection point.

摘要： Sensors detect rotational speeds of respective vehicle wheels. A slip detection reference value is calculated from the detected rotational speeds of the vehicle wheels. Acceptable slip ranges for the respective vehicle wheels are determined in accordance with the calculated slip detection reference value. The rotational speeds of the vehicle wheels are compared with the corresponding acceptable slip ranges respectively. Slip controls of the respective vehicle wheels are performed when the rotational speeds of the vehicle wheels reside outside the corresponding acceptable slip ranges respectively. The highest of at least two of the rotational speeds of the vehicle wheels is selected. Differences between the respective rotational speeds of the vehicle wheels and the selected highest vehicle wheel rotational speed are calculated. The slip detection reference value is corrected in accordance with the respective calculated differences.
