A motor vehicle has at least two drive motors, at least one of which is an electric motor, a high-voltage accumulator, and an automatic transmission which has at least one fixed gear ratio and at least one power-split gear ratio for transmission ratio adjustment starting from the at least one fixed gear ratio. The motor vehicle includes an electronic control unit having a speed control module which can be activated during a change of transmission ratio. The speed control module is designed in such a way that a setpoint speed is calculated in advance, by which setpoint speed both the speed gradient and also the speed curvature can be limited, the target speed of the at least one drive motor being continuously compared with a maximum allowed speed gradient and with a maximum allowed speed curvature.
