Abstract

In connection with a user interface for a motor vehicle with a hybrid drive, a driver is able to select whether the hybrid drive is operated in an operating mode which consumes charge, or in an operating mode which retains charge. The user interface is configured to display the charge state of the energy store on a display, and to receive or calculate a charge state variable which is characteristic of the charge state. The charge state variable may be displayed with a first range of values in a first display area during operation of the hybrid drive in the charge-consuming operating mode. The charge state variable may be displayed with a second range of values, which is a subset of the first range of values, in a second display area during operation of the hybrid drive in the charge-retaining operating mode. The second display area is larger than a subrange of the first display area in which the second range of values is displayed.
