  • Method and device for monitoring the function of an output stage having pulse width modulation
    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.

  • Method and device for monitoring the function of an output stage having pulse width modulation
    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).
