Safety assembly for preventing opening of a vehicle lock under predefined vehicle conditions

A method of controlling a latch of a safety assembly for preventing the opening of a trunk lock under predefined vehicle conditions, the safety assembly comprising a transmission element which is engaged by an interior-side actuating element and a trunk-side actuating element and which is coupled to a trunk lock, wherein a latch is provided which is adjustable between an actuating position, in which an actuating force can be transmitted from at least one of the actuating elements to the trunk lock, and a blocking position, in which an actuating force is not transmitted to the trunk lock, a gearing and a brushless electric motor being associated with the latch, wherein the latch can be transferred between the actuating position and the blocking position by the gearing and the brushless electric motor,

• the method being carried out by means of a controller that receives a speed signal and a trunk lock signal, wherein
• a) the controller controls the electric motor and moves the latch to the blocking position as soon as it receives a speed signal which is above a predefined threshold value when the trunk lock is partly open;
• b) the controller controls the electric motor and moves the latch back to the actuating position as soon as the controller receives a speed signal which is below the predefined threshold value again;
• and
• c) when controlling the electric motor, the controller receives a signal of the electric motor from which the controller can infer the position of the latch.
