Abstract: A control system for at least one direction indicator of a motor vehicle, based on environmental sensors of the own motor vehicle. The environmental sensors are adapted to detect the position of the motor vehicle on a lane of a road currently being driven on. An operating element which may be operated by the driver of the motor vehicle is provided and is adapted to be imprinted with a lane changing request by the driver of the motor vehicle for changing a lane currently being driven on. A direction indicator is provided and adapted to indicate the driver's lane changing request. A controller is further provided and is adapted to cause an indication of a lane changing request transmitted to the operating element by the direction indicator.
