Charging flap system for a motor vehicle

A charging flap system for a motor vehicle having a charging port on a side thereof, comprising:

• a charging flap movable between a closed position closing the charging port and an opened position exposing the charging port;
• an electric drive unit that moves the charging flap between the opened position and the closed position;
• an electronic control unit for controlling the drive unit;
• a blocking device for locking or releasing the charging flap in the closed position;
• a monitoring device for detecting a locked state or a non-locked state of the charging flap in the closed position;
• and
• a monitoring system associated with the control unit and comprising the monitoring device, the monitoring device comprising a control function for the control unit and a monitoring function for the blocking device that interact with one another such that the control function moves the charging flap in a direction of the opened position when the charging flap is in the closed position, and the monitoring function records, in a time-dependent manner, at least one current change parameter of the drive unit allowing detection of the locked or non-locked state of the charging flap in the closed position, wherein the at least one current change parameter comprises a current phase change evaluable by the control unit of the drive unit.

A charging flap system for a motor vehicle, the charging flap system comprising:

• a charging flap;
• an electric drive unit operatively connected to the charging flap to move the charging flap between a closed position and an open position, the charging flap in the closed position closing the charging port and in the open position exposing the charging port;
• a blocking device cooperating with the charging flap to lock or release the charging flap in the closed position, the blocking device having a blocking state preventing substantial movement of the charging flap when in the closed position to define a locked state of the charging flap, the blocking device having an unblocked state allowing movement of the charging flap when in the closed position to define a non-locked state of the charging flap;
• and
• an electronic control unit connected to and controlling the drive unit, the electronic control unit comprising a monitoring system configured to detect the locked or non-locked state of the charging flap in the closed position, the monitoring system comprising a control function for the control unit and a monitoring function for the blocking device, the control function moving the charging flap in a direction of the open position when the charging flap is in the closed position, and the monitoring function comprising recording at least one parameter in a time-dependent manner to permit detection of the locked or non-locked state of the charging flap in the closed position.
