摘要： In order to adapt an anti-lock brake system to the condition of the road surface, which may be dry or slippery, in an electronic control circuit the reference value for the rate of change of the wheel speed of a braked wheel, i.e., the deceleration and the acceleration, is varied in time from a fixed initial value for deceleration to a given acceleration value. This variation is made operative, as soon as the solenoid of the valve mechanism in the hydraulic brake connection is energized by the control circuit. As the case may be, a fixed time delay before the variation occurs may be built in. Steps are also taken to suppress effects of noise pulses and oscillations in the wheel suspension, and in the case of a very slippery road surface the control circuit is reset after a given time.

摘要： An anti-lock brake system for a wheeled vehicle which includes a control element for varying brake pressure and a damper piston arranged in a fluid cavity and coacting with the control element for regulating the movement of the control element during the anti-lock cycle. The dampened motion of the control element will effectuate a rapid initial and more gradual final rate of reapplication of the brake pressure.

摘要： A control circuit for a vehicle anti-lock brake system that includes a wheel sensor that produces electric signals proportional to the wheel speed, a control circuit responsive thereto to produce an electrical output when the wheel deceleration exceeds a given value, and a control valve responsive to said electrical output to release the braking pressure. The control circuit includes a pulse generator that produces a series of pulses during an anti-lock period. If the wheel continues to decelerate despite the release of the braking pressure, then the control circuit continues to supply output pulses at a rate which is a function of the wheel deceleration until the wheel deceleration no longer exceeds said given value.

摘要： A frequency-to-DC converter circuit for producing an output voltage related to the frequency of a train of input pulses. The circuit includes an improved ''''diode pump'''' circuit in which the input capacitor discharges through a diode only to a given reference voltage different from ground potential during the period between successive input pulses. The reference voltage approximates the instantaneous voltage across the circuit storage capacitor. The output voltage is preferably taken from the junction of an RC time constant circuit. The converter is especially adapted to provide a speed signal in an anti-lock brake system.

摘要： An anti-lock solenoid valve mechanism which includes a fluid pressure differential member for controlling the flow rate of fluid through the mechanism when the latter is energised. This member is displaced against the armature by the pressure differential across it due to fluid flow past it and displaces the armature against the solenoid magnetic force towards its closed position to reduce fluid flow until a state of equilibrium exists in which the armature is held by the resultant forces in a position in which it has to undergo only minimal displacement to close the solenoid valve on de-energisation.

摘要： An anti-lock vehicle brake control system includes a control circuit that energizes the brake solenoid when the wheel deceleration exceeds a reference value. The normal energization period of the solenoid is determined by the time it takes for the released wheel to again reach the reference value speed. On a slippery road it takes longer for the wheel to reach the reference value. When the normal energization period exceeds a given time period indicative that braking occurs on a slippery road, the control circuit extends the period of solenoid energization so that the wheel speed approximates the vehicle speed before the brakes are reapplied.

摘要： A circuit for deriving an output voltage that is proportional to the frequency of a train of input pulses. The input pulses charge a first capacitor and are also applied to an RC timing circuit. Between pulses the charge on the timing capacitor decays approximately as a rectangular hyperbola to produce a corresponding reference voltage. If and when the reference voltage reaches a given voltage level, the first capacitor begins to discharge and follows the reference voltage until it is recharged upon receipt of the next input pulse. An output terminal is coupled to the first capacitor to derive an output voltage proportional to the input pulse frequency.

摘要： An anti-lock vehicle brake control system comprising a wheel sensor for generating a train of pulses at a frequency proportional to the wheel speed. A switching transistor receives the pulses. A first capacitor is coupled to the output of the switching transistor via a first isolation diode. The switching transistor causes the first capacitor to charge up to a predetermined voltage level for each pulse received. A discharge circuit allows the first capacitor to discharge in the interval between successive pulses. A second capacitor is permanently connected to a source of charging current and is also coupled to the first capacitor via a second isolation diode so that the second capacitor will discharge towards the voltage level on the first capacitor to produce a voltage on the second capacitor that is proportional to wheel speed. The latter voltage is used to actuate a control valve in the vehicle brake fluid pressure system to relieve the braking pressure whenever said capacitor voltage exceeds a given value.
