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.

User interface and method for a motor vehicle with a hybrid drive for displaying the charge state

A method is provided for switching a drive of a hybrid vehicle from one operating mode to another operating mode. The drive includes an internal-combustion engine, at least one propulsion-generating electric machine and a transmission. The transmission can be shifted by a selecting device to be actuated by a driver into different operating states. The operating modes are distinguishable according to the ratio of drive power generated by the electric motor to the drive power generated by the internal-combustion engine. The drive is controlled by a drive control unit as a function of a drive prompt specified by the driver by an accelerator element and the selecting device, and according to different drive state and/or vehicle parameters. The drive is switchable from one operating mode to another operating mode by actuating the selecting device.
