    摘要： The system includes sensors (w) which provide signals indicative of the rate of rotation of at least one monitored wheel of the motor vehicle and electrically-controlled fluid actuators (4-9) for increasing and reducing the braking pressure applied to the braking elements of the vehicle. An electronic processing and control unit (30) connected to the sensors(W) and is arranged to pilot the actuators (4-9) in conditions of incipient locking of the wheels so as to bring about one or more cycles of anti-lock braking. In each of these cycles, the unit (10) causes in succession:
    a controlled reduction of the braking pressure when the at least one monitored wheel is in a condition of incipient locking,
    the holding of the pressure at a constant value until the acceleration of the monitored wheel exceeds a minimum positive threshold, and
    the increase of the braking pressure again. During the stage in which the braking pressure is increased again in each cycle after the first, the electronic unit (10) causes in particular:
    an initial pressure increase of an amount calculated on the basis of the total increase in the previous cycle and the durations of the last and penultimate periods of controlled reduction of the braking pressure, and
    a subsequent, slower increase in the braking pressure.

    摘要： The circuit comprises an amplitude limiter (3) made up with the use of two CMOS transistors (MP1; MP2) and a circuit (4) connected to the output of the amplitude limiter (S) for filtering the signal and changing its level. The filtering and level-changing circuit (4) is arranged, in particular, to achieve band-pass filtering in order to prevent aliasing effects which might arise during the sampling of the signal by subsequent switched-capacitance processing circuits, and to attenuate low-frequency components of the signal.

    摘要： The system comprises
        at least one spark plug (SP).
        at least one ignition coil (10) whose secondary win­ding (12) is connectible to the at least one plug (SP) to generate a spark,
        at least one controlled commutator device (13) adap­ted to assume first and second conditions to permit and to interrupt respectively the flow of a current (I) in the primary winding (11) of the at least one ignition coil (10),
        a device (15-17) for monitoring the intensity of the current (I) flowing in the primary winding (11) of the i­gnition coil (10),
        electrical sensors (3-6) which provide signals indi­cative of the operating conditions of the engine, and
        an electronic control unit (7) arranged to pilot the commutator device (13) in a predetermined manner accord­ing to the signals provided by the sensors (3-6) and by the device (15-17) monitoring the current (I) in the pri­mary winding (11) of the ignition coil (10).
    The control unit (7) is provided with memory devices (8) in which there are stored data indicative of predetermin­ed, final values (I fi ) for the current (I) in the primary winding (11) of the ignition coil (10), associated with various operating conditions of the engine identifiable from the signals provided by the sensor (3-6). The con­trol unit (7) is also arranged to pilot the commutator device (13) so that, each time a spark needs to be gene­rated, the flow of current in the primary winding (11) of the ignition coil (10) is stopped when the magnitude of this current has reached the value (I fi ) which is asso­ciated in the memory devices (8) with the prevailing ope­rating conditions of the engine, indicated by the sensors (3-6).
    The ignition system is thus able to "modulate" the energy of the spark, adjusting it to the operating conditions of the engine.

    摘要： In order to reapply the fluid operating pressure to the braking members of the wheels after an anti-locking operation has been carried out, pumping means (8, 10, 12) are provided which are driven by the subatmospheric pressure (vacuum) existing in the inlet manifold (D) of the engine. The application of the braking pressure is controlled by a valve (3) which receives an opening command signal consisting of a train of pulses from a control device (18). At least one vacuum sensor (19) is provi­ded which generates a monitoring signal indicative of the level of vacuum present in the inlet manifold (D). The control device (18) causes opening of the valve (3) with a command signal whose average value is inversely pro­portional to the level of the monitoring signal genera­ted by the vacuum sensor (19).
