摘要： An anti-skid control system for a vehicle with at least one wheel. The anti-skid control system includes a wheel sensor for sensing a rotational speed of the wheel and for generating a signal indicative of the sensed wheel speed and a brake sensor for sensing a braking force of a braking device which brakes the wheel and for generating a signal indicative of the sensed braking force. The wheel sensor and the brake sensor are respectively coupled to a control unit for receiving the wheel speed signal and the braking force signal to control the braking force of the braking device to a target braking force so that a slip ratio of the wheel assumes a predetermined value. The control unit determines the target braking force at the time of start of the anti-skid control to be equal to a braking force corresponding to the resultant of torques developed in the wheel at the control start time.

摘要： A method for controlling an automotive anti-skid brake system allows control for braking pressure at each wheel independently of other wheels. The anti-skid brake control is initiated in response to a drop of wheel acceleration across a predetermined wheel deceleration threshold. In the anti-skid brake control operation, braking pressure for at least two wheels are released in synchronism with each other. On the other hand, increasing rate of the braking pressure at the synchroneously released wheels are varied to each other so that when one of the wheels causes wheel-locking, the other wheel is held in a non-locking condition, This assures that the derivation of the vehicle speed representing value will be based on the wheel speed of the other wheel which is not locking and to assure prevention of locking at any wheels.

摘要： An anti-skid brake control system derives number of sensor signal pulses to be ignored without sampling the input timing data is cyclically increased in stepwise fashion until the signal-to-signal interval or the duration of each group of sensor signal pulses become larger than a predetermined value. Immediately after determining the number of sensor pulses to be ignored, the sensor signal pulses input subsequently is sampled its input timing value as the first sampled timing data. After sampling the first timing data, system enters sample control mode to ignore the determined number of sensor pulses so as to sample the input timing data with respect to every given number of sensor signal pulses.

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： A wheel lock control system is described which utilizes both independent and select low modes of wheel lock controlled braking. When braking on a surface in which the coefficients of friction between the two sides of the vehicle are substantially different or when the vehicle is undergoing severe steering maneuvers while braking, the wheel lock control system utilizes a select low mode of braking for the vehicle rear wheels so as to maintain vehicle stability. However, when the four wheels are being braked on a substantially uniform coefficient of friction surface, the wheel lock control system utilizes an independent mode of braking for each of the wheels of the vehicle so as to minimize the vehicle braking distance.

摘要： A method for controlling an anti-lock brake system for automotive vehicles with all-wheel drive. Electric signals representative of the rotational behavior of the wheels are generated and logically combined. Upon the occurrence of a tendency to lock, the braking pressure is modulated wherein the instantaneous wheel slip, wheel acceleration and wheel deceleration are evaluated as control criteria and the individual wheel speed (v.sub.R) is compared in each case with a vehicle reference speed (v.sub.REF) which serves as a reference value for the modulation of braking pressure. In the event of a wheel rotational behavior that is typical of spinning and that shows in the rise of the vehicle reference speed (v.sub.REF) in excess of the actual vehicle speed (v.sub.FZG), the control concept is modified until a specific point of time by deleting the instantaneous wheel slip as a control criterion for this phase of spinning and by the brake slip control becoming dependent on solely wheel acceleration or wheel deceleration.

摘要： To modulate the pressure reduction when controlling wheel slip by means of an anti-lock hydraulic brake system, electric signals representative of the rotational behavior of the individual wheels are reconditioned and combined electronically. Upon the occurrence of a tendency to lock, a pressure-reducing valve (17, 17', 19, 19', 21, 21') is actuated pulsewise, and thereby pressure fluid out of the wheel brake cylinder is returned into a supply reservoir (11). When varying the pulse/pulse-pause ratio of the actuating signals (i.sub.AV), additionally the pressure/time characteristic curve of the brake system is taken into consideration by increasing the pulse/pulse-pause ratio after a predetermined period of time, that is time of pressure reduction or number of pulses, with the pressure-reducing signal continuing to exist. The change in the actuating signals (i.sub.AV) for the improvement of the pressure reduction is effected in one or in several steps or quasi-continuously.

摘要： An anti-skid brake control system includes a fluid pump which facilitates brake release when wheel deceleration, as indicated in a derived wheel acceleration value, exceeds a predetermined level. Since at low vehicle speeds, the sensors used to derive the wheel acceleration value are of unsatisfactory accuracy, the wheel acceleration value itself may be inaccurate. Accordingly, at low vehicle speeds, the fluid pump is effectively disabled by replacing the derived wheel acceleration value with a fixed value less than the predetermined level.

摘要： An anti-skid brake control system performs arithmetic operations for deriving wheel speed on the basis of wheel sensor signal pulses at a first given timing. The first given timing is determined in view of response characteristics of an electromagnetic actuator of a pressure control valve in a hydraulic brake system. The anti-skid control system also performs arithmetic operations for deriving wheel acceleration on the basis of wheel speed sensor signal pulses at a second timing. The second timing is adjusted according to the sensor signal pulse frequency so that the difference between successive pulse intervals or the difference between the durations of successive sensor signal pulse groups exceeds a given value which is the threshold for performing wheel acceleration calculation to obtain a result useful in anti-skid control operation. Perferably, the anti-skid brake control system is provided with a plurality of digital processors, each of which is adapted to perform anti-skid brake control operations for a corresponding vehicle wheel or wheel set. Each of the digital processors can operate independently of the others and independently produces control signals for optimizing the braking characteristics of the corresponding wheel.

摘要： An anti-skid brake control system for an automotive vehicle has a control module comprising one or more microcomputers. The microcomputer is connected to a wheel speed sensor, which supplies a sensor signal indicative of the wheel speed, and a timer which outputs a timer signal indicative of the elapsed time. The microcomputer has an input time data sampling program for latching the timer signal value and storing the latched timer signal value as input time data for the corresponding sensor signal pulse. The input time data sampling program is executed as an interrupt program independent of a main program which processes the input time data and controls application and release of hydraulic braking pressure to a vehicle wheel in such a manner that wheel speed is adjusted toward an optimum relationship with vehicle speed. The microcomputer is also provided with a flag register which is incremented everytime the main program is interrupted for execution of the input time data sampling program and decremented at the end of each cycle of execution of the main program. The microcomputer repeatedly executes the main program until the register value of the flag register becomes equal to zero.
