METHOD FOR OPERATING A CONTROL DEVICE OF A MOTOR VEHICLE FOR AN ADAPTIVE ENERGY SAVING MODE AND CONTROL DEVICE AND MOTOR VEHICLE

The invention relates to a method for operating a control device (17) of a motor vehicle (10), wherein while the motor vehicle (10) is travelling a charging location (24) at which it is anticipated that an energy store (12) of the motor vehicle (10) will be charged the next time is estimated, and as a function of a current state of charge (22) of the energy store (12) a residual range (25) of the motor vehicle (10) which it is still possible to cover until a predetermined residual state of charge (27) of the energy store (12) is reached is estimated, and it is checked whether the residual range (25) is sufficient to reach the charging location (24). If the residual range (25) is shorter than a distance to the charging location (24), a respective quantity of electrical power (14), which is fed at least to an electrically powered vehicle component (11, 16), is respectively reduced, wherein the overall power reduction which is brought about as a result is only of such a magnitude that the residual state of charge (27) is reached when the charging location (24) is reached.
