Abstract

A motor vehicle has two drive units that can be operated jointly or individually to generate drive torque. The motor vehicle also has a device for predefining a driver's request. The device for predefining the driver's request is embodied so that a force level (K) with an increased restoring force is present within an adjustment range of the device. A control unit processes the driver's request and generates a control signal for actuating the drive units. The control unit operates so that, starting from a driving mode in which only one drive unit for generating a positive drive torque is active, switching over occurs from one drive unit to the other or the other drive unit also is activated when the force level is exceeded. At least one feature that characterizes the force level (K) can be varied based peripheral conditions.
