Method of operating a motor vehicle driven electrically at least temporarily on a roadway, control unit for a motor vehicle, and corresponding motor vehicle
First Claim
1. A method of operating a motor vehicle driven electrically at least temporarily on a roadway, said method comprising:
- moving the motor vehicle fully autonomously in response to a command for automatic operating mode;
executing a lateral control of the motor vehicle to electrically contact an extended charging arm with a charging line arranged at or on the roadway to generate electric energy for charging an energy accumulator of the motor vehicle and/or operating a drive device of the motor vehicle for moving the motor vehicle;
executing a longitudinal control of the motor vehicle to thereby maintain a predefined longitudinal speed until a distance of the motor vehicle reaches a predefined minimum distance to a leading vehicle; and
adjusting the longitudinal speed of the motor vehicle to a first default speed after issuance of the command for automatic operating mode, and adjusting the longitudinal speed to a second default value once the charging line has been contacted by the charging arm,wherein the second default value is greater than the first default speed and the second default value is set to a first value in response to no leading vehicle being detected, and the second default value is set to a larger second default value in response to a leading vehicle being detected, the larger second default value being greater than a current speed of the leading vehicle.

Abstract
In a method of operating a motor vehicle driven electrically, at least temporarily, on a roadway, the motor vehicle is moved fully autonomously by a control unit in response to a command for automatic operating mode. After a charging arm of the motor vehicle has been extended, a lateral control of the motor vehicle is executed to bring the extended charging arm into electric contact with a charging line arranged at or on the roadway. As a result, electric energy provided from the charging line to the charging arm is used for charging an energy accumulator of the motor vehicle and/or operating a drive device of the motor vehicle for moving the motor vehicle. A longitudinal control of the motor vehicle is executed to thereby maintain a predefined longitudinal speed of the motor vehicle until a distance of the motor vehicle reaches a predefined minimum distance to a leading vehicle.
