For operation of a motor vehicle () having a propulsion system (), when a critical operating state (STATE_CRIT) occurs and/or an operating error (ERROR) of the motor vehicle () and/or of the propulsion system () of the motor vehicle () occurs, the critical operating state (STATE_CRIT) and/or the operating error (ERROR) are signalled to a driver of the motor vehicle () by a reaction of the propulsion system () and/or by a reaction of the motor vehicle () which can be perceived by the driver.

Method and apparatus for operation of a motor vehicle

For the operation of a motor vehicle (), when a critical (CRIT) operation state (STATE) of the motor vehicle () and/or a drive system () of the motor vehicle () is detected in which an operation error (ERROR) can occur, a driver of the motor vehicle () is signaled (SIG) that there is a critical (CRIT) operation state (STATE). When the operation error (ERROR) occurs, the system is switched into a limited operation (LIMIT) of the drive system ().

Method and device for operating a motor vehicle

In a method for controlling the operation of an internal combustion engine, a target torque to be produced is determined in several steps: In a first step a torque requested by a user is determined and modified in subsequent steps by different functions, which reproduce the influences of at least one continuously determined working and/or operating parameter of the engine on the torque that is actually produced, in such a way that at the end of the steps the target torque required during the engine operation is defined and the engine operation and the determination of the working and/or operating parameter are monitored for errors. If errors occur, diagnostic values that describe or indicate the errors are generated and used to modify, in particular limit the target torque. The diagnostic values are individually assigned to the individual steps to modify the determination or modification of the torque performed in each step.

Device and method for controlling a drive unit

A method for determining the driver torque setpoint uses inputs from a drive pedal sensor, which senses the pedal position of a drive pedal. Depending on at least one switching parameter, different modes of calculation are activated, thus enabling the pedal position to be assigned to the driver torque setpoint. After the switchover from an old mode of calculation to a new mode of calculation, the driver torque setpoint is progressively adjusted, starting from the driver torque setpoint under an old interpretation of the pedal position, corresponding to the old set of characteristics, towards the driver torque setpoint under a new interpretation of the pedal position, corresponding to the new set of characteristics, and specifically in dependence on the time graph of the pedal position and simultaneously as a function of time, disregarding the time graph of the pedal position.
