SYSTEM FOR PROHIBITING TO CHANGE DRIVING DISTANCE OF VEHICLE AND THE DRIVING DISTANCE UPDATE METHOD USING THEREOF

摘要

PURPOSE: A vehicle travel distance tamper-proof system and a vehicle travel distance updating method are provided to prevent the driving distance manipulation when selling a vehicle as a second hand. CONSTITUTION: A vehicle travel distance tamper-proof system comprise an ECU(electronic control part, 160), a cluster ECU(110) and a gateway(120). The ECU performs a characteristic control function. The cluster ECU produces the cumulative driving distance of the vehicles and stores. The cluster ECU transmits the cumulative driving distance information stored with gateway. When the starting of the vehicles is turned on, gateway synchronizes to the big cumulative driving distance information. When the starting of the vehicles goes out, it transmits the information saved in the cluster ECU with ECU and gateway synchronizes.
