Abstract
A method for operating a drive system having at least one drive engine for a motor vehicle, having the following: carrying out an acceleration monitoring of the motor vehicle, a changeover to an alternative monitoring being made when the acceleration monitoring can no longer carry out a reliable monitoring, and, in the alternative monitoring, an engine rotational speed being limited to a maximum permissible engine rotational speed; and ascertaining the maximum permissible rotational speed as a function of a rotational speed specification specified by a driver's request.
Claims15
A method for operating a drive system having at least one drive engine for a motor vehicle, the method comprising:
- carrying out an acceleration monitoring of the motor vehicle, a changeover to an alternative monitoring being made when the acceleration monitoring can no longer carry out a reliable monitoring, and, in the alternative monitoring, an engine rotational speed being limited to a maximum permissible engine rotational speed;
- and
- ascertaining the maximum permissible rotational speed as a function of a rotational speed specification specified by a driver's request.
A device for operating a drive system having at least one drive engine for a motor vehicle, comprising:
- a monitoring arrangement configured to carry out an acceleration monitoring of the motor vehicle, a changeover to an alternative monitoring being made when the acceleration monitoring can no longer carry out a reliable monitoring, and, in the alternative to monitor, an engine rotational speed being limited to a maximum permissible engine rotational speed;
- and
- an ascertaining arrangement to the maximum permissible rotational speed as a function of a rotational speed specification specified by a driver's request.
A drive system, comprising:
- at least one drive engine;
- and
- a device for operating the drive system having the at least one drive engine, including:
- a monitoring arrangement configured to carry out an acceleration monitoring of the motor vehicle, a changeover to an alternative monitoring being made when the acceleration monitoring can no longer carry out a reliable monitoring, and, in the alternative to monitor, an engine rotational speed being limited to a maximum permissible engine rotational speed;
- and
- an ascertaining arrangement to the maximum permissible rotational speed as a function of a rotational speed specification specified by a driver's request.
A machine-readable storage medium having a computer program, comprising:
- a program code arrangement having program code for operating a drive system having at least one drive engine for a motor vehicle, by performing the following:
- carrying out an acceleration monitoring of the motor vehicle, a changeover to an alternative monitoring being made when the acceleration monitoring can no longer carry out a reliable monitoring, and, in the alternative monitoring, an engine rotational speed being limited to a maximum permissible engine rotational speed;
- and
- ascertaining the maximum permissible rotational speed as a function of a rotational speed specification specified by a driver's request.
