Abstract: A device and a method for evaluating a sensor signal indicating the position of an accelerator pedal of a motor vehicle. For this purpose, the device compares the sensor signal to a first comparison level, and an idle state is ascertained if the first comparison level is undershot. When a start of the motor vehicle from rest is detected, a departure from the idle state is inferred if a second comparison level, which is lower than the first comparison level, is exceeded.

Abstract: A method for controlling a drive unit of a vehicle includes forming a desired value for the torque of the drive unit in dependence upon the driver command. The formation of the desired value takes place in different ranges of the driver command with different weighting of the load dependency. The desired value in the mid range is independent of different loads of the drive unit.

Abstract: A method and an arrangement for controlling the drive unit of a vehicle are suggested. In a first step, input quantities, which are independent of the drive unit, are applied to form a first input quantity. In a second step, a second input quantity is formed from at least this first input quantity and at least one engine-specific input quantity, the second input quantity influencing at least an actuating quantity of the drive unit. In addition, an interface is described between the engine-independent part and the engine-specific part of the engine control.

Abstract: The invention is directed to a method and an arrangement for controlling a drive unit of a vehicle wherein maximum permissible value is pregiven for monitoring purposes for the output quantity for the drive unit. In this value, requirement values of at least one consumer and/or one ancillary function are included. The inclusion only takes place when the at least one consumer and/or the ancillary function is actually active. To determine whether the consumer and/or ancillary function is active, two pieces of data as to the activation state are evaluated, which pieces of data are independent of each other.

Abstract: The internal resistance of a lambda probe is determined by: the application of a clocked direct-current counter voltage to the probe via a series resistor; the measurement of the output voltages with the counter voltage connected and disconnected; and, the calculation of the internal resistance from the measured values and known resistance values.Apart from the components of a conventional arrangement, this method requires only a series resistor and a switch for implementation. Measurement can be carried out at short time intervals without excessively high direct-current voltage loading which affects the service life.The internal resistance measured is compared with a desired resistance and the control deviation determined in this way is used to determine the duty factor for probe heating clocked with fixed frequency.

Abstract: In a method for determining the exhaust gas temperature, the internal resistance of a lambda sensor is measured, and it is determined whether lean or rich mixture is present. Depending on which mixture type is present, the exhaust gas temperature associated with the measured internal resistance value is read out from one of two internal resistance value/exhaust gas temperature characteristic curves. This method can be used correspondingly for determining the sensor temperature from the internal resistance.The exhaust gas temperature determined as above only applies accurately for steady-state cases. In order to obtain satisfactory values even in non-steady-state cases, the exhaust gas temperature is averaged in a sliding manner. The present exhaust gas temperature is determined from the particular average value and the particular rise in the exhaust gas temperature/time curve.The mentioned methods permit the exhaust gas temperature to be determined without a separate temperature measuring element.
