摘要： In an anti-skid vehicle braking system an electronic control unit is arranged to control the operation of an anti-skid valve assembly for modulating the fluid pressure applied to a brake actuator. A wheel speed sensor measures the speed of a braked wheel and produces a signal which is converted into a deceleration signal by a conditioning circuit and a differentiator and compared in a comparator with a deceleration threshold value. A pressure sensor provides a pressure signal corresponding to the current brake actuator pressure and a pressure signal conditioning circuit modifies the pressure signal to take account of a load signal produced by a load sensor which measures the loading of the braked wheel. The deceleration threshold value is produced by modulation of a constant threshold value in a threshold generator circuit and a threshold modulator circuit in response to the modified pressure signal. The threshold value is varied in response to the current pressure signal in accordance with a predetermined relationship between the threshold value and the brake actuator pressure, with a higher threshold value being provided for a higher actuator pressure. When the system is applied to the brakes of a low inertia axle, an over-ride circuit is included to provide a signal which over-rides the pressure signal for an initial period when the brake is applied as detected by a brake lamp switch.

摘要： An ABS skid detection protection system for a wheeled vehicle detects a predetermined level of deceleration at a wheel; detects, memorizers and holds for a prescribed period the wheel speed value at that predetermined deceleration level; detects whether the angular acceleration of the monitored wheel first falls below and then re-establishes the predetermined deceleration level within the prescribed level; and corrects the memorizsed value of wheel speed by subtracting from it an amount equal to the vehicle deceleration multiplied by either the elapsed time since the wheel speed value was memorized or the elapsed time since the initiation of a short-duration pulse by which the actuating pressure applied to a brake can be temporarily dumped upon detection of the predetermined level of deceleration of the wheel.

摘要： An anti-lock braking system for a road vehicle having a plurality of hydraulically operated brake actuators, a plurality of control channels controlling the supply of hydraulic fluid to the brake actuators, an electrical supply and a hydraulic pump for supplying hydraulic fluid to the brake actuation circuit. The pump is driven by an electric motor energized by the power supply. The magnitude of the operating voltage at the pump motor is compared with a predetermined reference voltage. The physical demand upon the pump motor is reduced by inhibiting the control channels if the measured magnitude of the electric motor voltage is less than the reference value.

摘要： An anti-lock system for vehicle brakes of the type wherein a computer is used to process data received from wheel speed transducers and to control the release of the brake of a particular wheel when the deceleration and/or slip of that wheel exceeds predetermined thresholds. In order to increase the immunity of the system to road irregularities while maintaining skid detection sensitivity, it is arranged that, during periods that anti-lock is not currently evoked, the detection of a road bump at the front axle is used to cause the rear axle anti-lock system to be temporarily de-sensitized just before it would be expected, on the basis of speed and wheel-base, to reach the same bump. Bump recognition at the front wheel(s) is achieved by identifying those occasions when front wheel speed deviation exceeds a predetermined "window" threshold level which is chosen to correspond to the bump severity needed to overcome the normal rear axle "first cycle" threshold but which does not meet the criteria needed to evoke the front axle anti-lock system.
摘要翻译：一种用于车辆制动器的防抱死系统，其中计算机用于处理从车轮速度传感器接收的数据，并且当车轮的减速和/或滑动超过预定阈值时，控制特定车轮的制动器的释放。为了在保持滑行检测灵敏度的同时提高系统对道路不规则的免疫力，布置为在防抱死当前未被诱发的期间，前桥的道路凸起的检测被用于使后方轴防抱死系统将在预期的基础上，在速度和车轮基础上暂时消除敏感，达到相同的碰撞。通过识别当前轮速度偏差超过预定的“窗口”阈值水平时，通过识别这些情况来实现前轮处的凸起识别，该水平被选择为对应于克服正常后桥“第一循环”阈值所需的碰撞强度，但是这不符合唤醒前桥防抱死系统所需的标准。

摘要： An anti-lock ABS braking system for a road vehicle includes a respective dump valve for each brake actuator which enables pressure to be selectively dumped from that actuator to release the braking action of the relevant rear wheel. Whether a given rear wheel of the vehicle is still operating in a stable condition is established, as is the aggregate dump valve time of the rear wheel opposite to that under consideration. The brake pressure at the still stable rear wheel is allowed to continue to rise for a prescribed period and then its dump valve is actuated for a period corresponding to the measured aggregate dump time of the opposite rear wheel.

摘要： An anti-skid braking system for wheeled vehicles having fluid actuated brakes associated with the vehicle wheels, speed sensors associated with the vehicle wheels and a cyclically operating control device which is responsive to speed signals from the speed sensors to actuate a pressure dump device to periodically release the fluid pressure applied to the brake of any wheel which is determined to be about to lock and to later re-apply the actuating pressure to that brake when the tendency of that wheel to lock has reduced, and wherein the pressure dump phase is arranged to be cancelled during wheel-lock when the aggregate dump time for the current cycle exceeds a limit value based upon a weighted-average dump time of previous cycles.

摘要： In a suspension system which is designed to maintain a nominal ride height between the body and the unsprung parts of a vehicle, the difference in wheel speed on opposite sides of the vehicle produced during cornering is used to inhibit adjustment of ride height.An electrical sensor and control unit is used to control flow of hydraulic fluid to and from a suspension unit by means of solenoid-operated valves, so as to maintain the ride height constant. A cornering sensor compares the sensed speeds of two wheels, preferably mounted on a common axle, and inhibits the control unit when the difference in speeds departs from an expected difference by more than a certain amount. The expected difference may be zero or it may be the average difference derived over a period of time.
