![]() Data by BI Intelligence shows about 75% of the cars sold by 2020 will be connected (Figure 3). Within just a few years, the majority of automobiles will be “connected”-to the Internet, to the occupants’ mobile devices, and to each other and the road’s infrastructure. ![]() Architecting-and spec’ing components for today’s connected car-are a designer’s challenge. Designers need to account for 10-year life cycle requirements, wicked EMI mitigation and “dirty” power, plus all manner of temperature extremes in a moist and corrosive environment. The IVI console is actually a collection of many embedded systems that rely on the efficiency of the PCIe interface. The IVI system block diagram reveals sensors and graphics, media processors, packet-based networks, and PCI Express peripherals. High-end auto manufacturers offer more features-such as front-mounted radar or 360-degree camera vision-but even the lower tier brands include back-up cameras, smartphone integration (and Google’s Android Auto or Apple’s CarPlay) along with Bluetooth and smart device charging (Figure 2).įigure 2: Android Auto. The center console IVI system is a consumer must-have item and differentiates car brands. Yet the hotter topic for automotive designers now is the car’s “connectedness” to the Internet, advanced safety features like lane departure or self-parking, and in-vehicle infotainment (IVI).įigure 1: Today’s automobiles are loaded with networks, cameras,Īnd the all-important center console in-vehicle infotainment (IVI) system. Regarding “car tech,” we take for granted that every window motor, headlamp and trunk release has its own MCU there might be a hundred MCUs and sensors interconnected via networks in the modern car (Figure 1). Move over CANbus, PCI Express is the latest communications technology found in automotive infotainment.
