Claim 0:
1. A motor vehicle comprising:
at least two drive motors, wherein at least one drive motor is an electric machine;
a high-voltage battery;
an automatic gearbox comprising:
at least one fixed gear ratio and at least one power-split gear ratio (E-CVT); and/or
at least one serial gear ratio for gear ratio adjustment towards the at least one fixed gear ratio; and

an electronic control unit configured to, during a ratio adjustment between an engagement of a shift element and a loading of the shift element, in order to control an internal combustion engine and the electric machine:
cause the shift element to be loaded with a predefined torque gradient at a first point in time at which at least one tooth-on-tooth position exists up to a second point in time;
cause the predefined torque to be limited to a maximum permissible torque during a predefined waiting period from the second point in time up to a third point in time; and
cause the shift element to be further loaded with the previously defined torque gradient after the waiting period or when an engaged state is detected.
