  • Patent number: 7089142
    Abstract: A method and a device for monitoring at least one output stage which is actuated by a microcontroller using an input signal having any pulse duty factor. The output signal from the output stage is averaged by an electrical circuit and compared to a setpoint value which is calculated from the input signal of the output stage. An error in the output stage is diagnosed when the averaged value deviates from the calculated setpoint value.

  • Publication number: 20040130354
    Abstract: The present invention relates to a method and a device for monitoring at least one output stage (1) which is actuated by a microcontroller (&mgr;C) using an input signal (2) having any pulse duty factor. The output signal (3) from the output stage (1) is averaged by an electrical circuit (4) and compared to a setpoint value (5) which is calculated from the input signal (2) of the output stage. An error in the output stage (1) is diagnosed when the averaged value (6) deviates from the calculated setpoint value (5).

  • Patent number: 5982280
    Abstract: The invention relates to a system for monitoring a clutch between a motor of a vehicle and a transmission thereof with respect to impermissible slip. For this purpose, the monitoring system provides that a value is determined with the presence of specific operating conditions. This value represents the slip present at the clutch. This value can then be compared to at least one pregiven first threshold value. With the system of the invention, the clutch is monitored with respect to clutch wear which has already occurred. In one configuration of the invention, the clutch is configured as a converter bridging clutch and is generally configured with an automatic transmission; whereas, in another configuration of the invention, a clutch is considered which can interrupt the frictional connection between the motor of the vehicle and the transmission when the clutch is completely disengaged.
