  • Method for controlling an electrically driven compressor
    Patent number: 6922996
    Abstract: An electrical booster in an internal combustion engine with an exhaust gas turbocharger is activated so that the electrical booster is connected with the minimum possible power consumption. The connection of the electric booster depends on the power balance, the electric booster being activated when the instantaneously available compressor power of the exhaust gas turbocharger is insufficient to provide the necessary power.

  • Method for checking analog sensors
    Patent number: 6421625
    Abstract: After the start of an internal combustion engine, a check is made to see whether a positive change in a measurement signal is established. A positive change is established if the measurement signal lies below a predetermined threshold value when the internal combustion engine is started. A fault entry is made if, within a predetermined time period, the positive change in the measurement signal, expressed as the difference between the measurement signal when the internal combustion engine is started and a present value of the measurement signal when the time period has elapsed, does not reach an expected value.
