A vehicle door lock is disposed in a vehicle door and includes a ratchet wheel rotatable between a locked position where it captures a lock catch disposed on a vehicle body and an unlocking position where it releases the lock catch to allow the vehicle door to be opened. The vehicle door lock further includes an ice-breaking mechanism disposed in the vehicle door, and the ice-breaking mechanism applies a torque to the ratchet wheel to cause the ratchet wheel to rotate in a direction to push the lock catch so as to open the vehicle door. The vehicle door lock can be opened by pushing the ratchet wheel with e ice-breaker mechanism when the vehicle door is frozen or deformed due to collision, the operation noise is low, the cost is low, and the paint surface of the vehicle door is protected.

A device includes a support, a handle mounted pivotably with respect to the support, a lever for actuating a lock of the door configured to cooperate with an extension element of the handle extending transversely from an inner face of the handle. Moreover, the lever is mounted movable on an axis of articulation of the support against a resilient return member between a first rest configuration of the member in which it extends across a path of the extension element to generate a stress resisting the pivoting of the handle and a second configuration of actuation of the lock in which it is driven in rotation about said axis by the extension element during the pivoting of the handle after having overcome the resisting stress.

A single-door control circuit for a train includes a first circuit for controlling a single door when the train is in a sleep state, and a second circuit for controlling a door of the train when the train is in a wake-up activated state. When the train is in the sleep state, the second circuit is not electrified, the first circuit works, a door control unit is electrified by a storage battery power supply, and the single-door control is triggered by an electric unlocking switch or a single-door button; and when the train is in the wake-up activated state, the first circuit is cut off, the second circuit is electrified, and under a condition that a cab on a local side is activated and the train is at a zero velocity, the single-door control is only triggered by activating the single-door button in the cab.

A system controls a stop function or a door opening function of a vehicle. The system includes an actuating element which is designed to generate an actuation signal depending on an actuation by a vehicle occupant, and a control device which is designed to receive the actuation signal and, in response to receiving the actuation signal and depending on a travel velocity of the vehicle, to trigger either the stop function or the door opening function.

A motor vehicle closing device having a locking mechanism with a catch; at least one pawl, said catch being latchable in at least one latching position by means of the pawl; a lock holder, wherein the lock holder can be brought into engagement with the catch by means of a relative movement between the closing device and the lock holder, and the locking mechanism can be converted into a latching position; and means for locking the lock holder in a main latching position of the locking mechanism. According to the invention, a holding device is provided. The holding device is used to convert a vehicle part which interacts with the motor vehicle closing device from a closed position into an open position, and the holding device forms at least one part of the means for locking the lock holder.
