A motor vehicle door lock, such as a motor vehicle bonnet lock includes a locking mechanism which substantially consists of a rotary latch and a pawl. The locking mechanism interacts with a striker element on a bonnet. The lock further has an unlocking/opening mechanism for the bonnet, which mechanism is equipped with a release element provided in the interior of a motor vehicle body. The release element is operated twice to open the bonnet. The locking mechanism is transferred to a pre-latched position after the release element has been operated at least once, with the striker element still being trapped. The bonnet is opened from the pre-latched position by lifting the pawl off the rotary latch with the aid of a power mechanism, said lifting being activated separately.

A method for detecting a closed position of a movable part of a vehicle, in particular an automatically operable vehicle, said method comprising the following steps: a control unit receives a first position signal from a first signal source as a first closure criterion which comprises at least one locking position of a vehicle lock for the movable part; the control unit adds a conditional test instruction to the received first position signal, wherein the conditional test instruction comprises checking for at least one second position signal as a second closure criterion after detecting the first position signal, wherein the first closure criterion is also satisfied; the control unit receives the second position signal from a second signal source as a second closure criterion, wherein the second signal source is different from the first signal source and the second position signal can be assigned to the movable part; the control unit outputs a confirmation signal when both closure criteria are satisfied.

A latch assembly for a closure system having first and second closure members each movable between open and closed positions and method of operation are provided. The assembly includes a primary latch mechanism that has a primary actuation group to control actuation of the first closure member. The latch assembly also includes a secondary latch mechanism that has a secondary actuation group operable to control actuation of the second closure member. A controller unit is coupled to the primary and secondary actuation groups and determines which of the primary actuation group and the secondary actuation group to actuate and controls actuation of at least one of the primary actuation group and the secondary actuation group accordingly. The primary and secondary latch mechanisms, primary and secondary actuation groups, and controller unit are all integrated into the housing.

A power latch and presenter assembly for latching and releasing a closure panel and for moving the closure panel from a closed position to a presented position includes a ratchet moveable between a striker capture position and a striker release position. A pawl is configured for movement between a ratchet holding position, whereat the pawl maintains the ratchet in the striker capture position and a ratchet releasing position. A power release actuator is configured to move the pawl from the ratchet holding position to the ratchet releasing position and to move a presenter arm between a non-deployed position, whereat the presenter arm is spaced from the striker, to a deployed position, whereat the presenter arm engages the striker to move the closure panel from the closed position to the presented position. A power presenter actuator is configured to move the presenter arm from the non-deployed position to the deployed position.

A vehicle door control device 1 according to the present invention relates to a vehicle door control device 1 for controlling opening and closing of a door of a vehicle, wherein the vehicle door control device 1 comprises: a handle member 30 attached to the door; an entry detection sensor 31 for detecting entry of an object into a space between the door and the handle member 30; an external force detection sensor 32 for detecting application of an external force to the handle member 30; and a circuit portion 4 connected to the entry detection sensor 31 and the external force detection sensor 32, the circuit portion 4 releasing a latch of the door when the external force detection sensor 32 detects the application of the external force and the entry detection sensor 31 detects the entry of the object.
