Wireless ECU reprogramming for multiple vehicles in factories and service centers via WiFi

Electronic control unit (ECU) reprogramming entails the software update of vehicle ECUs, to improve the performance or correct errors by injecting a program into the internal ROM of the ECU or by changing an existing program. ECU reprogramming is typically performed in factories and service centers. Manufacturing process procedures and recall situations are typical examples. To date, when reprogramming is conducted in a factory, the workers use wires and adapters to individually operate each vehicle. In this paper, we propose a model for simultaneously reprogramming multiple vehicles using WiFi in specific spaces, such as factories and service centers. In addition, the model detects the loss or corruption of data transmitted wirelessly for reprogramming.
