Long gone are the days when ‘in car audio’ referred to a crackly radio or maybe a built-in tape deck or CD player. In all but the most basic versions, the in-vehicle infotainment (IVI) is a ‘hub’ within the vehicle, providing many functions including safety, guidance and entertainment. In fact, the capability and convenience of the IVI system is high on the list of decision-making factors for modern car buyers.
However, designers of these IVI systems face a number of challenges; vehicles contain more electronics than ever before and modern EV and HEV are switching huge currents, all of which makes for an electrically noisy environment. As communication between different systems is critical to delivering the high-tech experience, so the IVI system needs to be able to interface with many other areas of the vehicle including several camera systems, navigation and more. And, of course, consumers are demanding the highest level of audio quality at the lowest possible price.
