3.6.1. Overview

The Latch Manager component controls the locking and unlocking of the vehicle doors, bonnet and boot based on central lock commands and door open requests. It detects mislock events and vehicle movement to determine the appropriate latch states.

3.6.2. Functions

	Title	Description
1	Central Lock Control	Controls the locking and unlocking of all doors based on the central lock command. Sends latch requests to individual door latch components.
2	Mislock Event Detection	Detects mislock events where a door, bonnet or boot is ajar when attempting to lock. Sends a mislock event signal if detected.
3	Vehicle Movement Detection	Detects if the vehicle is moving based on vehicle speed and a configurable threshold and timeout. Sends a vehicle moving status.
4	Bonnet and Boot Lock Control	Controls the locking and unlocking of the bonnet and boot based on open requests, vehicle lock status and configuration parameters.
