into the domain controller there has become an increased interaction between IVI and other critical vehicle functions. However, with the integration of additional interfaces - such as driver monitoring, eMirrors, etc. In earlier IVI systems, allocating functional safety requirements to the different components led integrators to accept “quality management” (QM) memory devices. To achieve ASIL certification, the infrastructure supporting the critical information was historically isolated from other vehicle functions and modeled as deterministic with high availability. Some key vehicle components are covered by ASIL certifications Integrators have various options under ISO 26262 requirements for integrating semiconductor components into their systems, such as: using components with the same ASIL as the system, performing ASIL decomposition and performing a hardware evaluation of the component, etc. The level of ISO 26262-compliance required will first be established at the system level based on hazard analysis, which considers failure severity, controllability and exposure. The integrity of the safety-critical information is vital. Then, a second domain controls other connectivity in the vehicle, separately enabled by a telematics control unit (TCU) and often isolated by a secure gateway. The first domain is for the safety-critical interface to the instrument cluster, which typically gets certified under the Automotive Safety Integrity Level B (ASIL-B). Certain information in the cluster is used to alert the driver to vehicle functions, and a portion of that information can have an impact on vehicle and passenger safety, so strict compliance requirements may apply.įor this reason, the domain controller architecture is divided into two domains. Despite the benefits, consolidation has its challengesĪs beneficial as this consolidation is, potential FuSa considerations may arise. At a system level this consolidation also reduces interface complexity. Having the graphics interchangeable between the IVI and cluster user interfaces offers an enhanced experience to the user. The processing platform in the IVI system already has a graphics capability, thus using this as a common domain controller helps eliminate system redundancy and provides overall system cost reductions. There are multiple motivations for this consolidation including cost reductions and delivery of a simplified architecture that accelerates opportunity for innovation. To meet these requirements, IVI system architecture has been integrated with the instrument cluster into a common architecture known as a domain controller. The emergence of digital instrument clusters introduces new graphics requirements. Designers are integrating IVI with the instrument clusters for more-critical systems that require functional safety (FuSa) compliance. Those in-vehicle infotainment (IVI) systems with their engaging, high-resolution screens and functions that increasingly emulate smartphones? They’re not just for fun anymore. Now there’s a new, somewhat-surprising development. Automotive manufacturers face constant pressure to combine processing power and keep digital systems streamlined and cost competitive. He believes that while some audio content will continue, two major innovations are creating fundamentally new entertainment needs: driverless cars and electric vehicles (EVs) requiring lengthy charging.Storing and processing massive amounts of data quickly is a requirement with today’s vehicles. Although the underlying technologies have changed, the core product was typically the same-audio content, including music, talk, news and podcasts. "If you consider the history of in-car entertainment, it began with the AM radio, moved to FM, then 8-track, tapes, CDs, MP3, and more recently satellite and internet services such as Spotify, Pandora and YouTube," he says. Rybchin specialises in customer experiences, particularly how changing consumer expectations and business model disruption impact various industries. "Infotainment in cars is approaching a critical inflexion point where many of the traditional forms of in-car entertainment are on the precipice of becoming extinct," says Iliya Rybchin, Partner at Elixirr, a consulting firm which has advised automotive and entertainment companies. In the wake of these trends, the entertainment offering is constantly evolving. Research suggests that the IVI market is driven by the increase in vehicle production, technological advancements, telematics regulations, and increasing demand for luxury vehicles. According to MarketsandMarkets, the in-vehicle infotainment (IVI) market is projected to grow from US$ 20.8bn in 2021 to US$28.4bn by 2027, at a CAGR of 10.8 %.
