Specifications

Relevant knowledge

The door lock controller is a control device that provides locking/opening pulse current for the door lock actuator. Regardless of the type of door lock actuator, the linkage is controlled to move left and right by changing the direction of the actuator’s current flow, achieving the locking and opening of the door lock. There are many types of door lock controllers, which can be roughly divided into three types based on their control principles: transistor type, capacitor type, and induction type

Transistor type: The transistor door lock controller has two relays inside, one for locking the door and the other for opening the door. The relay is controlled by a transistor switch circuit, which utilizes the charging and discharging process of the capacitor to control a certain duration of pulse current, enabling the actuator to complete the locking and opening actions.

Capacitive type: This door lock controller utilizes the charging and discharging characteristics of the capacitor. Normally, the capacitor is fully charged, and it is connected to the control circuit during operation to discharge the capacitor, causing the relay to power on and briefly close. After the capacitor is fully discharged, its contacts are disconnected through the interruption of the relay’s current, and the door lock system is no longer in use.

Vehicle speed sensing: Equipped with a sensing switch with a speed of 10km/h. When the vehicle speed exceeds 10km/h, if the door is not locked, the driver does not need to touch it, and the door lock controller automatically locks the door.
