摘要： To decrease the braking distance or braking path of a vehicle equipped with an automatic brake anti-lock or automatic anti-skid system, under unusual operating conditions in which the wheels on one side (right) are on a slippery surface, for example ice, and the wheels on the left side (L) of the vehicle are on a high-friction surface, for example clear roadway, without introducing excessive yaw during braking, pressure drop in the brake line at the low-friction side is sensed and braking pressure increased at the high-friction side after elapse of a predetermined timing interval, regardless of continued decreased braking pressure at the low-friction side; the increase in braking pressure at the high-friction side preferably occurs in pulses (.DELTA.P), the pulse lengths and pulse gaps of which are a function of vehicle speed (v).

摘要： An antiskid braking system includes an improved lead apparatus for generating a lead signal to provide lead compensation. According to this invention, the gain of the apparatus is made to vary as a function of a signal, such as the brake control signal generated by the antiskid system, which is indicative of the coefficient of braking under severe braking conditions. Preferably the gain of the lead apparatus is varied independently of the gains of other elements of the antiskid system, such as the modulator, for example.

摘要： An anti-locking brake force regulating device for rail vehicles has a digital evaluation circuit which monitors the speed, acceleration and slip of at least one braked wheel and transmits braking instructions to a brake actuating element. The instructions include a rapid or slow increase or decrease of brake pressure or maintaining the brake pressure constant. In order to achieve a smooth control during a braking operation, the evaluation circuit is such that after instructing a rapid change of brake pressure in response to exceeding a predetermined threshold value a slow change of brake pressure in the same direction as the rapid change is instructed if the threshold value is again exceeded and the slow pressure change begins by a maintaining brake pressure constant phase. The slow or pulsed brake pressure change is preferably maintained for a fixed predetermined period of time.

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： A skid control device employs a wheel speed sensor and the control circuit which includes a microcomputer. The microcomputer computes wheel speed on the basis of a pulse signal derived from the wheel speed sensor and delivers a break releasing signal when the wheels slip. A brake control apparatus for controlling the pressure of oil for applying the brakes to the wheels responds to the outputs of the microcomputer. The microcomputer contains a free-running counter which counts clock pulses and a memory containing a sequence of storage locations. This sequence of storage locations stores count values of the free-running counter. A pulse signal from the wheel speed sensor is employed to produce an interrupt request for the microcomputer. The contents of successively adjacent locations in memory are employed by the microcomputer for carrying out the necessary calculations and computing wheel speed.

摘要： A circuit arrangement for influencing the brake pressure venting phase and/or brake pressure retaining phase for an antiskid vehicle braking system when the measured velocity difference deviates from a given velocity difference during controlled braking. The velocity change is determined as a function of the wheel tendency or tendencies by measuring and differentiating the velocity value or values at the interval boundaries of an assigned time .DELTA.t of the control signals or by the assigned times of the control signals. A switching circuit, to which the brake pressure control signals, such as, the acceleration +b, deceleration -b and slip .lambda. control signals, and a signal representing the wheel tendencies, such as, either positive or negative velocity change of the sensed wheel or wheels, can be set upon drop away of a +b or -b signal. The switching circuit controls a shifting circuit which changes the assigned time .DELTA.t or some or all assigned times .DELTA.t or changes the switching times of the control signals as a function of the signal or signals indicating the wheel tendency or tendencies. Thus, the shifting circuit produces a high signal, a medium signal, or a low signal indication representing an appropriate assigned time .DELTA.t.

摘要： An anti-skid brake control system which is adapted to control the brake of a wheel comprising a brake release switch that produces a control signal to release the brake on detection of the onset of skidding of the wheel, a sensor for producing an electrical signal proportional to the angular acceleration of the wheel, a charging circuit which is responsive to the acceleration signal and produces a corresponding output signal so that the amplitude-time curves of the two signals cross-over one another after the acceleration peak resulting from release of the brake, and a brake re-applying switch which compares the acceleration signal and the output signal from the charging circuit and produces a control signal to re-apply the brake after the cross-over point. The charging circuit is preferably adapted so that the amplitude-time curves of the acceleration signal and output signal cross over one another after the deceleration peak as well as after the subsequent acceleration peak, and the brake re-apply switch produces a control signal to release the brake or hold the brake released or partially released during the period between the two cross-over points and to re-apply the brake after the second cross-over point.
