Evolving instrument cluster systems Automotive integrated cockpit control is a challenging space due to the integration of multiple and diverse cockpit functions. Besides the IVI and the Cluster systems, other ADAS functions such as DMS, FCW, SVS and connected vehicle telematic functionalities are finding attractive use-case and value add to the end customers. Many OEM’s are striving to deliver such high-level integration. The instrument cluster system in a vehicle informs critical driving information such as speed, RPM and tell-tale functions. The instrument cluster is a mandatory system for safe driving and is mounted in all mainstream vehicles. In modern ECU’s instrument cluster have stringent requirements to integrate safety compliance. At present, driver assistance functions and autonomous driving capability of the vehicle are progressing rapidly. This in turn increases the number of information transfer between the instrument cluster and various sensors, ECU’s and control devices. This is leading to an increased amount of information that the instrument cluster has to display and realize, including

complex visualization information on nearby vehicles while driving. At the same time, from the point of view of safety, the need for increased visibility is increasing, and it is necessary to render graphics smoothly. Digital cluster system rendered by automotive LCD displays are becoming the de-facto standard, and system evolution continues onward from there. 1. Cluster digitalization can support increased safety critical content and provide more user convenience. For example, it is possible to concurrently show a local map via smartphone connection and to safely warn driver using DMS (Driver Monitoring System). 2. Furthermore, Integrated Cockpit System growth is accelerating due to continued focus on CASE (Connected Autonomous Shared Services & Electronic) In summary, inurement cluster system needs to keep robustness despite the high level of system integration. Current solutions are using system isolation implemented by a hypervisor system and developing highly robust systems across all applications.
