Luggage compartment lid lift (3) controls and monitors opening or closing of the luggage compartment lid. Opening or closing of the luggage compartment lid can be triggered by luggage compartment lid buttons (8, 11, 13). The luggage compartment lid can be unlocked and opened by purely mechanical means with the lock barrel in the luggage compartment lid (4).
The signals from the outside temperature sensor (1) and vehicle speed (6) are evaluated to determine whether the luggage compartment lid may be opened or closed in response to a press of a button.
