As the electronics of the automobile industry develops, it gets to be actively researching on integration and convergence technical part. Especially, it is more aggressive on chassis systems in vehicles because of various requirements. The chassis control system of future automobiles is expected that electronic components are not only to be improved functionally but also to be integrated complicatedly. There is very advantageous in terms of high performance of a safe and convenient vehicle. This ultimately leads to be able to reduce unnecessary redundant sensors, so car makers could get price competitiveness effectively. Chassis control integration methods can be divided into three methods: (1) hardware integration, (2) software integration, and (3) hardware and software integration. All three methods should always consider ECU integration on hardware, and MCU-related design applied to the integrated ECU is an important consideration in software architecture design. In this paper, the second method, software integration method is adopted to be built in the ECU of the braking system among Chassis domain controllers. The ECU of brake system is the most suitable as the chassis integration ECU. Because it processes the important sensor signals of vehicles such as wheel sensors and direction sensors. This paper proposes the software architecture design for the software integration collaboration between supplier and vehicle manufacturer. And the proposed software architecture is verified by EILS and vehicles.
