摘要： A process and apparatus for regulating the operator-controlled brake pressure of a vehicle wheel to prevent wheel lock-up by sensing a lock-up tendency and independently varying the operator-controlled brake pressure at the skidding wheel during successive cycles of wheel skid control. The sensed wheel behavior is monitored by an evaluation circuit which measures the duration of brake pressure reapplication with constant gradient during an initial cycle, provides a time period during a subsequent cycle that is a predetermined time duration less than the time duration of reapplication pressure in the initial cycle, and following expiration of the reduced time duration, establishes reapplication of pressure with a pressure gradient lower than the gradient during the initial cycle, whereby the reapplication pressure during control cycles subsequent to the initial control cycle is with a stepped gradient.

摘要： A first amplifier measures the instantaneous voltage across a resistor, connected in series with the electromagnet of a solenoid valve, as the current increases following energization of the electromagnet. A second amplifier measures the same voltage and stores the peak value in a capacitor. The two measured voltages are applied to a comparator which detects the difference, and generates an output, when operation of the electromagnet armature causes a transient reduction in the resistor voltage. Initial energization of the electromagnet sets a memory and starts a monostable timing period. The set output of the memory primes one input of an AND gate, the second input being inhibited by the monostable output during timing. If the electromagnet armature operates normally, the comparator output resets the memory and removes the AND gate priming signal prior to completion of the timing period. If the armature fails to operate the monostable output following the timing period completes the actuation of the AND gate to produce a fault signal.

摘要： A component control arrangement for transit-type vehicles having a distributed plurality of vehicle components to be monitored and controlled, includes a number of function control modules, each being associated with a specific vehicle function; as for example, wheel-skid, climate-control, and verification systems. The function control modules, each communicate in a multiplex arrangement over a shared data bus and a transceiver arrangement, with a distribution unit. The distribution units have an output configuration allowing connection to a variety of vehicle operating devices including lamps, switches, solenoid valves, and electric motors. The function control modules evaluate status indications originating from the vehicle operating devices and transmitted through the distribution units and a transceiver arrangement. The function control modules utilize the status indications to derive control instructions for the vehicle operating devices based on a predetermined set of vehicle operating and safety parameters.

摘要： Signals representing actual and desired speeds of a vehicle are separately applied to a plurality of parallel comparator channels or devices. Each comparator device responds to a different level of difference between the speed signals, when actual is greater than desired, to produce output signals at successively higher levels. The first comparator device controls a first deceleration device, e.g., an exhaust throttle, to reduce vehicle speed when an output signal is produced at the first preselected level of difference. The second and third comparator devices control the second and third deceleration devices, respectively, e.g., an eddy-current brake, automatic transmission, etc., when each produces an output signal at its preselected difference level, but only if the next lower comparator output has enabled a gate or switch coupling the higher level comparator and deceleration devices. Thus the deceleration control is increased in successive steps as the speed difference increases if each successive deceleration device is actuated in order by the associated comparator.

摘要： A multiplex cabling system for controlling electrical apparatus on motor vehicles, which consists of a central transmitter and several area transmitter-receivers, each connected to several controlled devices and/or indicators. Coupling between the central transmitter and the area units is made by a star-arranged line system which consists of a separate, two-wire connecting channel between the central transmitter and each area transmitter-receiver. To further increase the system's reliability and security, the central transmitter includes two microprocessors which are normally assigned to control a different pair of diagonally-opposite area transmitter-receivers. If one processor fails, the other unit assumes full system control.

摘要： This disclosure relates to a method and an arrangement for filtering disturbing signals in the digital measurement of the cycle duration for an antiskid control system for motor vehicles. The detrimental influence of short disturbances on the production of control signals is suppressed by means of the filtering process. The production of the control signals takes place in accordance with the result obtained from a comparison of the respective measured value .tau..sub.n with a reference value .tau..sub.B. The filtering is carried out in a manner so that when a digital measured value .tau..sub.n enters, a new reference value .tau..sub.B', is produced as a function of the difference between the reference value .tau..sub.B and the mean value obtained from the reference value .tau..sub.B and new measured value .tau..sub.n.

摘要： A wheel speed measuring apparatus is provided for use in an anti-skid brake control system such that a digital speed signal is obtained having good accuracy without resorting to expensive manufacturing methods to assure exact conformity of the teeth and teeth spaces of the rotor member of the wheel sensor device used in the anti-skid control system. The speed measuring apparatus consists of at least two corresponding portions, each consisting of a control unit, a counter and a data register. The control unit of one portion responds to a positive polarity transition of the square wave signal generated by the wheel sensor, while the control unit of the other portion responds to negative polarity transitions, to initiate operation of the respective counters. The count output of each counter therefore provides a digital speed signal corresponding to a full cycle duration of the square wave signal, with one cycle overlapping the other to compensate for any deviations in the half-cycle durations due to size differences in the teeth and spaces of the rotor member of the sensor that generates the square wave signal.
