Abstract
The invention relates to a fleet security system comprising a vehicle security unit (VSU) to be installed inside each vehicle, on the sun visor or on the dashboard of the vehicle, and connected to the vehicle using the On-Board Diagnostics (OBD) connector of the vehicle. An authorized user holds the key of the vehicle to be used and an electronic security key. When the authorized user opens the door of the vehicle, the VSU detects a disturbance in the vehicle and wirelessly sends a disturbance event message to a fleet master unit. The authorized user then has a given deactivation time period (such as thirteen seconds) to show its security key to a key reader located inside the vehicle, on the VSU. The security key code is validated by the master unit which will command the VSU to disarm its disturbance detection.
