A verification system for a vehicle latch is provided. The system includes a switch operable to determine if a vehicle door is ajar. The system also includes a cam operatively coupled to a power release mechanism that actuates movement of the vehicle latch between an opened and closed position, the cam in operable contact with the switch, the switch also determining if the vehicle latch is in a fully reset condition or an un-reset condition.

Disclosed is an arresting system for arresting a swivel motion between two swivel-mounted elements, including a brake rod connected to the first element, an arresting device on the second element with a housing, through which the brake rod extends, in which case the arresting device has a drive and at least one brake-shoe element that can be moved via the drive relative to the brake rod. The brake-shoe element is inside the housing and engageable with the brake rod upon exertion of a braking force. Included are a sensor, and an electronic device controlling braking force exerted by the brake-shoe element on the brake rod depending on the signals from the sensor. The drive is an electric motor driving in rotation an actuation element that, to produce the relative motion between the brake-shoe element and the brake rod, has an actuation cam acting on the brake-shoe element.

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 motor vehicle door lock, particularly a motor vehicle bonnet lock, includes a ratchet mechanism which substantially consists of a rotary latch and a pawl. The ratchet mechanism interacts with a lock retainer pin on a vehicle bonnet. A retention element is additionally provided which holds the pawl in a retention position, raised from the rotary latch, during unlocking of the bonnet. The lock retainer pin continues to engage in the rotary latch when in said retention position. During a first opening process which proceeds from the retention position, the lock retainer pin transfers the retention element into a release position that releases the pawl. During a subsequent bonnet closing process, the pawl can thus engage in the rotary latch, which can be pivoted without exertion of force by the lock retainer pin at least into the hold position.

A vehicle door control system includes a courtesy switch that detects an opened/closed state of a side door, a latch actuator that performs an unlatch operation for releasing a latch that holds the side door in a closed state, an unlatch switch that is provided in a vehicle compartment and is operated by a user when releasing the latch, and a controller that causes the latch actuator to perform the unlatch operation when the unlatch switch is operated. The controller prevents the unlatch operation from being executed in a period during which the side door is in an opened state, even when the unlatch switch is operated.

A motor vehicle door lock, more particularly a hood lock. The basic structure of the hood lock is composed of a raising mechanism, for a locking bolt or another stop part, on a hood. An actuating spring acting on the raising mechanism is also provided, in addition to a sensor for sensing the position of the hood. According to the invention, an additional spring is provided which raises the hood if the actuating spring breaks down and/or malfunctions.
