A motor vehicle lock, in particular a motor vehicle bonnet lock. Same is designed with a locking mechanism substantially formed by a rotatory latch and a pawl for cooperating with a locking bolt. In addition, a catch hook is provided for independent and additional securing of a locking bolt. The locking mechanism is provided with a locking mechanism drive and the catch hook is provided with a catch hook drive. According to the invention, the locking mechanism drive and the catch hook drive are optionally actuated by motor vehicle signals.

A vehicle includes a compartment mounted to a frame of the vehicle. The compartment includes a box coupled to the frame in a fixed position relative to the frame and a latch system coupled to the box to allow a user to access the box. The latch system includes a shape-memory alloy wire guided by a pulley during actuation of the latch system.

A method and device for unlatching a door from a frame, using a keyless door latch system, is provided. In one embodiment, a secondary unlocking component receives a signal and derives power from the signal to provide a power source for the keyless door latch system. A microcontroller generates a control signal and an actuator, in response to receiving the control signal, actuates the secondary unlocking component, which allows an energy source, from an exterior of the door, to be transferred to the keyless door latch system for the unlatching of the door.

A central locking device for door locks of a motor vehicle includes a control device and, connected thereto, locking couplings in the door locks. An accident detection device is provided for determining an accident situation of the motor vehicle and for transmitting an accident signal to the control device. Upon receiving the accident situation signal, the control device is set up to switch the locking couplings to the locked status for a defined period of time and then to switch them to the unlocked status. This prevents disturbances that may occur in the region of the door handle during an acute accident phase, since the door handles are not functional during the defined period of time.

A tailgate opening/closing device has a simplified tailgate opening/closing structure, reduced manufacturing cost, reduced weight, and improved quality. The device includes a release gear configured to be rotated forwards and backwards by a rotational force from a motor, a cinching gear engaged with the release gear, a linkage mechanism configured to receive force from the cinching gear to rotate toward a claw, the claw being caught by the linkage mechanism to rotate together therewith so as to be engaged with a striker, and a pawl unit configured to be caught by the claw in the state in which the claw is engaged with the striker so as to restrict rotation of the claw and configured to allow rotation of the claw in a release operation direction only when the release gear rotates in the release operation direction.
