ICS (Intelligent Cockpit System) is a Human-Machine Interface (HMI) technology that integrates In-Vehicle Infotainment (IVI), Head Up Display (HUD), and Navigation (NAVI). The HMI technology stack in ICS involves engineering human-machine interaction creativity, component-based graphics systems and vehicle-level hardware system, etc. The HMI engine we developed is a middleware that implements human-machine interaction computing in in-vehicle electronic equipment, and the engine is also a software stack for graphics computing, scheduling management of computing devices in the cockpit and software runtime functions, it operates the display hardware through OpenGL. This paper introduces a COMO-based ICS HMI technology with functional safety SOA architecture. With the support of COMO RPC, devices are abstracted as services and integrated together. Under the premise of ensuring functional safety, it has a variety of ICS-oriented 2D, 3D controls with running state and design state, suitable for creative people and automotive engineers to work together.
