Method for operating a motor vehicle that can be driven electrically at least at times, a control device for a motor vehicle and a corresponding motor vehicle

摘要

A method for operating a motor vehicle (1) that can be driven electrically at least at times on a road (2), wherein a control device executes a fully autonomous driving mode of the motor vehicle (1) after an automatic mode is requested The previously extended charging arm (7) of the motor vehicle (1) comes into electrical contact with a charging line (6) arranged on or on the road (2), with electrical energy provided by the charging line (6) via the charging arm (7) an energy store of the motor vehicle (1) is charged and / or a drive device of the motor vehicle (1) is operated to carry out the driving operation, and longitudinal control of the motor vehicle (1) takes place in such a way that a predetermined longitudinal speed is maintained until a distance between the motor vehicle ( 1) reaches a predetermined minimum distance from a vehicle (12) in front, characterized in that the longitudinal speed is set to a first default speed after the automatic mode is requested and after contacting the charging line (6) by the loading arm (7) is set to a second default speed, the second default speed being greater than the first default speed and a first Value is set when no preceding vehicle is detected, and is set to a larger second value when a preceding vehicle is detected, the second value being greater than the current speed of the preceding vehicle.
