Vehicle upgrade system and method thereof
First Claim
1. A vehicle update system for updating a vehicle, the system comprising:
- a telematics unit that receives new ROM data transmitted from a telematics server;
an electronic control unit (ECU) configured to check that certain update conditions are satisfied and when the certain update conditions are satisfied, update old ROM data to the new ROM data;
a main battery configured to provide power to update the old ROM data to the new ROM data when the vehicle engine is on; and
an auxiliary battery configured to provide power to the ECU update the old ROM data to the new ROM data when the vehicle engine is off,wherein the update condition is that the charged state and the voltage level for at least one of the main battery and the auxiliary battery is larger than a certain level, the vehicle is in a stopped or parked state, and the controller area network (CAN) communication state of the vehicle is normal.

Abstract
A vehicle update system for updating a vehicle'"'"'s ROM data is provided. More specifically, a telematics unit is configured to receive new ROM data transmitted from a telematics server. An electronic control unit (ECU) is configured first check to determine whether certain update conditions are satisfied and when they are satisfied, update the old ROM data to the new ROM data using at least one of a main battery and an auxiliary battery. More specifically, the update conditions are that the charged state and the voltage level for at least one of the main battery and the auxiliary battery is greater than a certain level, the vehicle is stopped or parked, and the controller area network (CAN) communication state of the vehicle is normal.

13. A vehicle update method used in a vehicle, the method comprising:
-
receiving new ROM data transmitted from a telematics server by a telematics unit (step 1); checking, by an electronic control unit (ECU), whether certain update conditions are satisfied; and when the update conditions are satisfied, updating old ROM data to the new ROM data using at least one of a main battery and an auxiliary battery (step 2), wherein the update conditions are that the charged state and the voltage level for at least one of the main battery and the auxiliary battery is greater than a preset level, the vehicle is stopped or parked, and the controller area network (CAN) communication state is normal, and wherein the ECU performs the update using the auxiliary battery when the vehicle engine is off, and performs the update using the main battery when the vehicle engine is on. - View Dependent Claims (14, 15, 16, 17, 18, 19)
