  • Method of updating the transmissibility function of a clutch during a gear change
    Patent number: 6658340
    Abstract: A method of updating the transmissibility function of a clutch during the final stage of a gear change, in which the clutch is closed to cause the angular speed of the drive shaft to equal the angular speed of the primary shaft of the gear change, the engine is set to supply a constant torque, the clutch is disposed in a predetermined position in order to transmit a constant torque greater than the torque supplied by the engine and the actual value of the torque transmitted by the clutch is calculated by subtracting the product of the moment of inertia of the engine and the angular acceleration of the drive shaft from the torque generated by the engine, the actual value of the torque transmitted by the clutch then being used to update the transmissibility function of the clutch.

  • System for monitoring the efficiency of a catalyser, particularly for motor vehicles
    Patent number: 5715678
    Abstract: The efficiency of a catalyser is evaluated starting from output signals of two lambda probes disposed upstream and downstream respectively of the catalyser. In particular, a signal obtained by calculating the difference between the time averages obtained by integration and subsequent division for the duration of an integration window of output signals of these probes is used as the signal indicative of efficiency.
