US 2026/0156185 A1 · COMMUNICATION SYSTEM FOR A VEHICLE

Abstract

In certain embodiments, a control system for an electric vehicle includes an electronic control unit (ECU) bus and a plurality of ECUs. A first ECU executes a broker service that communicates with a network server over a network, receives state information from applications executing on the ECUs, generates subscription information based on the state information, and transmits the subscription information to the applications that are subscribed to the subscription information. The first ECU also executes a translation service that communicates with the broker service and the ECU bus, and an application that generates state information, sends the state information to the broker service, and receives subscription information from the broker service. The second ECU executes an application that transmits state information over the ECU bus to the first ECU, and receives subscription information over the ECU bus from the first ECU.
