Abstract: Based on an analysis of the existing test scenarios of the onboard system, this paper proposes an implementation scheme of the vehicle interface simulation system. The scheme divides the vehicle interface simulation system into three layers, i.e. information management layer, operation logic layer, and interface execution layer. The functions of each layer feature high cohesion and low coupling, which improves the adaptability of the test system and reduces the costs of building the test environment. This paper also elaborates on the structure and implementation of the vehicle interface simulation system from three aspects, i.e. system architecture, system composition and service process. Thus, it provides a new solution for establishing a general-purpose vehicle simulation test environment.
