Abstract
A control device in a motor vehicle outputs a gear-shift recommendation. The control device has an electronic control unit which can be coupled to an acoustic signal output unit. The control device includes a shift recommendation module for determining a current most economical target gear, a comparison module for determining the distance between the currently-selected actual gear and the target gear, and an acoustic output module for activating an acoustic recommendation signal according to the distance between the actual gear and the target gear.
Claims14
A control device in a motor vehicle for outputting a gear-shift recommendation, comprising:
- an electronic control unit which is coupleable to an acoustic signal output unit, the electronic control unit comprising:
- a shift recommendation module that determines a currently most economical target gear,
- a comparison module that determines a distance between a current selected actual gear and the target gear;
- and
- an acoustic output module that activates an acoustic recommendation signal via the signal output unit, depending on the distance between the actual gear and the target gear.
A method of outputting a gear-shift recommendation in a motor vehicle, the method comprising the acts of:
- Determining, via an electronic control unit, a currently most economical target gear;
- Determining, via the control unit, a distance between a current selected actual gear and the currently most economical target gear;
- and
- Activating, via the control unit, an acoustic recommendation signal depending on the distance between the actual gear and the target gear.
