As homes become more digitally sophisticated, consumers are developing higher expectations for connectivity and greater levels of safety and comfort in their home away from home—their vehicle. As a result, in-vehicle electronics are growing in number and complexity, keeping step with technology advancements and capitalizing on consumer expectations for a connected driving experience.
Collision warning, comfort controls, infotainment and advanced driver assistance are just some of today's sophisticated and diverse applications generating an increasing need for bandwidth and connectivity within and between in-vehicle networks. Answering these needs effectively is creating a significant competitive arena for innovation among automotive manufacturers and OEMs.
In such a market, vehicle electronics are no longer considered a series of distinct stand-alone components and are evolving into a more seamless in-vehicle network. By connecting through proven IP-based Ethernet technology, auto manufacturers have the means to bridge the gap between function and entertainment within a single network, while dramatically reducing connectivity cost and cabling weight.
Evolving Ethernet for automotive use
Ethernet is not unfamiliar to automotive electronics, but until recently its use was restricted to onboard diagnostics (OBD) rather than passenger-facing applications. In a service setting, with no passengers present and the engine off, a standard Ethernet connection was suitable for technicians to connect for testing and diagnostics. To make the shift from OBD applications to an in-vehicle network during engine operation, today’s Ethernet solutions must address the stringent requirements of the automotive industry, including electromagnetic compatibility (EMC), temperature tolerance, and emissions immunity.
