Abstract:
The present invention relates to a method for improving data processing performance of a vehicle gateway in real-time and a system for the same, which can improve the data processing performance of the vehicle gateway in real-time and prevent transmission error due to time delays by calculating the delay time for each message received by the gateway and adjusting the transmission priority in the gateway to allow message having the shortest allowance delay time to be transmitted first on the basis of the calculation.
