Abstract:
1. A method for providing information to a driver relating to an operational state of a motor vehicle having an electric motor to drive the motor vehicle with a fixed transmission ratio, comprising: during operation of the electric motor, continuously determining a virtual rotational speed and a virtual gear-shift stage from a first operational parameter describing the operational state of the motor vehicle; limiting or expanding a predefined range of operating states of the electric motor within which the electric motor can be operated, as a function of a second operational parameter describing the operational state of the motor vehicle, the second operational parameter being different from the first operational parameter; modifying, by a control unit, the virtual rotational speed and the virtual gear-shift stage to produce a virtual modified rotational speed and a virtual modified gear-shift stage, the virtual rotational speed and the virtual gear-shift stage being modified as a function of the second operational parameter; and producing an acoustic output as a function of the virtual modified rotational speed and the virtual modified gear-shift stage.
