Assembly line control system and immobilizer data protocol and communication process flow
First Claim
1. A method of registering data associated with a vehicle, comprising the steps of:
- entering a vehicle identification number into an assembly line control client of a production control system that is connected to a network;
comparing the entered vehicle identification number with an expected vehicle identification number from a database of an assembly line control server;
if a match is obtained between the entered and expected vehicle identification numbers, sending the vehicle identification number and an associated information record from the assembly line control client of the production control system to a vehicle Immobilizer, wherein the assembly line control client communicates with the database and the Immobilizer; and
writing the vehicle identification number and the associated information record from the Immobilizer into an electronic control unit incorporated into the vehicle.

Abstract
A method and related apparatus are disclosed of guaranteeing VIN registration to a vehicle'"'"'s ECU. A vehicle identifier is entered into a production control system connected to a network. The entered vehicle identifier is compared with an expected vehicle identifier. If a match is obtained between the entered and expected vehicle identifiers, the vehicle identifier is sent from the production control system to a vehicle Immobilizer. A vehicle identifier acknowledgement is received at the production control system from the vehicle Immobilizer. The production control system verifies the vehicle identifier embedded in the acknowledgement. If a match is obtained, an information record associated with the vehicle identifier is sent from the production control system to the vehicle Immobilizer. An information record acknowledgement is received at the production control system from the vehicle Immobilizer. The production control system verifies the information record embedded in the acknowledgement. If a match is obtained, an authorization message is sent from the production control system to the vehicle Immobilizer. The vehicle identifier and the associated information record from the vehicle Immobilizer are written into an electronic control unit incorporated into the vehicle in response to the authorization message. The vehicle Immobilizer then continues to write other data into the vehicle'"'"'s ECU. After all the writing is complete, the vehicle Immobilizer reads from the vehicle'"'"'s ECU the vehicle identifier and the information record, and sends them back to the production control system for final verification. If the two pieces of information from the ECU match the two pieces of information held by the production control system, the production control system sends a complete message to the Immobilizer and records the VIN registration record in the central database. Upon receiving the complete message, the Immobilizer resumes to its ready state and the ECU data registration process is complete.

13. A system for registering vehicle data comprising:
-
an assembly line control client of a production control system that is connected to a network and to an entering implementation; a vehicle Immobilizer for encoding data into an electronic control unit incorporated into a vehicle; the entering implementation for entering a vehicle identification number into the assembly line control client of the production control system; a sending implementation including an RS232C interface, incorporated into the production system, for sending the vehicle identification number and an associated information record from the production control system to the vehicle Immobilizer; and a writing implementation including a communications connection, incorporated into the vehicle Immobilizer, for writing the vehicle identification number and the associated information record from the vehicle Immobilizer into the electronic control unit, the production control system further comprising; a comparing implementation including the assembly line control client, for comparing the entered vehicle identification number entered with the entering implementation with an expected vehicle identification number from a database of an assembly line control server, wherein the assembly line control client communicates with the database and the Immobilizer; and a determining implementation for determining if a match is obtained between the entered and expected vehicle identification numbers, and for instructing the sending implementation to send the vehicle identification number and the associated information record to the vehicle immobilizer. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
