Summary

In this video, the concept of central locking systems (centralog) in vehicles is explained. The presenter describes how central locks work, including the main components such as the main unit, battery, actuators, and door lock switches. The video demonstrates how pressing the driver's door lock switch will lock or unlock all doors simultaneously. The explanation covers the roles of the main door lock and additional door locks, highlighting the difference in their wiring. Lastly, the presenter explains the function of relays and how they operate when locking or unlocking doors, with a brief mention of alarms in the system.

Takeaways

• 😀 Central lock (centralog) is a system that allows for locking and unlocking all vehicle doors simultaneously by pressing a switch, typically located on the driver's side.
• 😀 Central lock systems can also be controlled via remote or keyless entry systems, providing ease of use and added security.
• 😀 The central lock system consists of several components: the main unit (brain of the system), battery, actuators, main and additional door locks, and door lock switches on both the driver and passenger sides.
• 😀 The main unit controls the locking and unlocking of doors, functioning as the 'brain' of the central lock system.
• 😀 The battery powers the central lock system, ensuring the functionality of all components.
• 😀 Main door locks are located on the driver's door and feature five cables, while additional door locks on the passenger doors have only two cables.
• 😀 Pressing the door lock switch on the driver's side will lock all doors, while pressing it again will unlock all doors. This system works in a parallel fashion for other doors.
• 😀 The central lock system can be easily activated or deactivated through a switch, and when unlocked, all doors will open simultaneously.
• 😀 The difference between the main and additional door locks is the number of cables they have—main door locks have five cables, while additional door locks have only two.
• 😀 Two relays are used in the central lock system—one for locking and one for unlocking. These relays control the direction of the current that activates the door locks.
• 😀 The central lock system can be connected to an alarm system, allowing it to integrate with vehicle security features for added protection.

Q & A

What is central locking (centralog) in vehicles?

Central locking, or 'centralog', is a system that allows all doors of a vehicle to be locked or unlocked simultaneously by pressing a single switch, either on the door or using a remote control.

What are the key components of a central locking system?

The main components of a central locking system include the main unit, battery, actuators, door lock switches, and relays.

How does the central locking system work?

When the door lock switch is pressed, it activates a relay, sending a signal to lock or unlock all the doors. The relay works by controlling the direction of current flow, which either locks or unlocks the doors.

What is the difference between a main door lock and an additional door lock?

A main door lock is found on the driver's door and has five cables, whereas an additional door lock is found on passenger doors and has two cables.

What is the role of the main unit in a central locking system?

The main unit acts as the brain of the central locking system, controlling the locking and unlocking of all doors based on the signals from the door lock switches.

How do relays function in a central locking system?

Relays control the flow of current in the system. When activated, a relay connects the battery's positive current to the door lock actuators, causing them to lock or unlock the doors.

What is the significance of the central locking system’s integration with an alarm?

The central locking system can be connected to an alarm system, allowing the vehicle's security features to work in sync, ensuring both the locking mechanism and alarm are triggered at the same time.

How is the locking direction determined in the central locking system?

The direction of locking or unlocking is determined by the activation of the relay. When the relay is activated in one direction, the doors are locked; in the opposite direction, the doors are unlocked.

How does a remote control or keyless entry system work with central locking?

A remote control or keyless entry system, often referred to as 'KES', can be used to lock and unlock the vehicle doors without physically pressing a switch. The remote sends a signal to activate the central locking system.

What are the advantages of having a central locking system in a vehicle?

The main advantage of a central locking system is convenience, as it allows all doors to be locked or unlocked simultaneously with a single action, enhancing both security and ease of use.
