FIELD OF INVENTION
This invention relates to an approach to keep track of fuel usage during manufacturing of vehicles and also fuel economy of the vehicle when rolled-out of assembly line to dealers/customers. The system mentioned in this document maintains fuel usage at the time of manufacturing and fuel economy of each vehicle based on test drive after vehicle assembly. The system will be integrated to ERP system to maintain information related to each vehicle.
BACKGROUND OF THE INVENTION
As part of assembly process, a fixed quantity of fuel is filled in tank before vehicle is taken for test drive. After test drive, the vehicle is dispatched to dealers/customers. Each vehicle dispatched should have a pre-determined amount of fuel in tank. Amount of fuel in tank will be accounted in pricing of vehicle. Presently this process of fuel quantity inspection and filling is done manually based on individual estimate and judgment. This often leads to excess amount of fuel filled in tank. The excess fuel filled is not accounted in pricing of vehicle.
SUMMARY OF THE INVENTION
The system described in this document shall fill the tank with pre-determined amount of fuel during tank assembly. The amount of fuel filled shall be logged in ERP system corresponding to vehicle ID. The vehicle shall be equipped with a RFID transmitter to identify its unique configuration/specification. The system

shall log the initial odometer value (kilometers traveled) in ERP system. Once vehicle is back from test drive, the system shall log amount of fuel remaining in tank and current odometer information. Based on distance traveled information and fuel consumed, the system shall calculate fuel economy of the vehicle during test drive. The system shall log this information in ERP system. Finally the system shall fill the tank with pre-determined amount of fuel and update ERP system. This system will be useful tool for audit.

The detailed operation of the system can be explained with the help of block diagram of the system and its interaction with its accessories (Figure 1). This system is installed and located in vehicle assembly line. The entire process approach can be explained through the following steps in sequence: -
1. Vehicle fuel tank is assembled in vehicle manufacturing line and it arrives to location where System is located.

2. System identifies the vehicle's unique configuration or specification through the RFID tag present in the vehicle. System logs the vehicle ID in the ERP system through its TCP/IP communication interface.
3. System controls the fuel dispensing system through suitable communication interface to fill fixed amount of fuel in tank before test drive. This fuel filled information is logged in ERP system
