    摘要: An electronic control system for fuel metering in an internal combustion engine includes, inter alia, means for determining a basic injection-quantity signal and a transition compensation signal for adapting the quantity of fuel metered-in in the case of acceleration and deceleration, in which, for the purpose of transition compensation, a wall-film quantity signal and a discharge factor signal (Tk) are formed as a function of load and rotational speed, and the transition compensation signal takes into account both the wall-film quantity signal and the discharge factor signal. The discharge factor signal can either be read from a characteristic map or assume two discrete values. The proposed system serves the purpose of achieving a transitional behavior which is as optimum as possible with respect to the exhaust gas.

    摘要: An arrangement for controlling the drive power of a motor vehicle has at least two control units for controlling at least two changing variables for influencing the drive power. The variables are independent of each other. The arrangement further includes at least one measuring device for detecting an operating variable of the drive unit and/or of the motor vehicle. This one measuring unit includes at least two redundant sensors with the output signal of one sensor being supplied to a first control unit and the output signal of another sensor being supplied to a second control unit. Both control units monitor the measuring device on the basis of the output signals with additional monitoring measures being carried out on the basis of the monitoring results of the two control units.
