Abstract

The invention relates to a system for realizing software upgrading control for multiple electronic control units of an automobile. The system comprises automobile domain controllers and automobile ECUcontrollers. A single automobile domain controller is connected with the multiple automobile ECU controllers in a star connection mode to form a local CAN network, the automobile domain controller isconnected with one or more different automobile ECU controllers, and the multiple automobile domain controllers are connected in a point-to-point mode. The invention further relates to a software upgrading control method for the multiple electronic control units of the automobile. By the adoption of the system and method for realizing software upgrading control for the multiple electronic controlunits of the automobile, it can be effectively guaranteed that a data path is normal, data exchange can be effectively conducted, CAN bus data loads can be effectively reduced, and connection of multiple ECU controllers can be supported. The method has multiple upgrading modes, has good expansibility and application scene adaptability, and greatly improves the upgrading efficiency.
