![]() And the IVI connects to the car’s CAN bus, Ethernet, USB, PCIe, and other wired networks.ĥG is replacing 4G as the standard for IVI systems. Bring-your-own-device (BYOD) connectivity is supported by several IVI SoCs that tightly integrate users’ smartphones with the IVI system. It includes Wi-Fi networking and wireless charging. Smartphone connectivity is growing in importance in IVI systems. For a deeper dive into these developments, check out the FAQ on “What are the five levels of vehicle connectivity?” Various levels of connectivity are emerging that support value-added services for drivers and passengers. IVI MCUs are required to manage connections to Wi-Fi (including the creation of local networks), smartphones, wireless sensors, GPS, and other devices. IVI SoCs will incorporate machine learning accelerators to support improved accuracy.Ī connected vehicle has been defined as one equipped with Internet connectivity and able to send and receive data. Vertical-cavity surface-emitting laser (VCSEL) technology is also being considered for gesture recognition. Technologies for gesture recognition include mmwave radar and ultrasonics. Gesture control is being developed for IVI systems. ![]() These systems will require an IVI that can identify the driver and monitor facial features to determine driver attention. Driver monitoring systems are beginning to appear and are expected to be mandated by safety regulatory bodies. Biometrics can also be used to limit access to specific features and prevent theft. IVI systems are also available that support biometric authentication, like facial recognition or fingerprint scanning, to provide a more secure and personalized experience. Advanced systems have been proposed using millimeter wave (mmWave) radar to detect and categorize passengers versus packages and other objects in the cabin, enabling the IVI to be more proactive and interactive. IVI systems provide a wide range of information and entertainment functions and connectivity (Image: Infineon ).Ĭars are becoming independently aware of passengers. The trend is toward personalization and flexibility through software-defined functions that are replacing centralized architectures with distributed computing capabilities, more memory, and faster connectivity ( Figure 1). A variety of MCUs will be required to support audio and video interfaces for drivers and passengers and to add new comfort and entertainment applications as well as advanced driver assistance capabilities. In advanced designs, the domain controller can also monitor the driver’s attention and focus on driving. The cockpit domain controller coordinates driver information and control functions using touch screens, software-defined controls, and voice commands. IVIs provide the command center for vehicle operations and support for essential services. This FAQ begins with a brief overview of IVI functions including emerging advanced functions like driver attention monitoring and gesture recognition, looks at the growing demand on IVIs for expanded connectivity, presents a typical IVI system architecture, typical IVI MCU functionalities, and a typical IVI system on chip (SoC) and closes with a brief review of security and safety standards related to IVIs and other automotive systems. Software-defined functionality and over-the-air (OTA) updates are also important. Considerations include connectivity, human-machine interfaces (HMIs) beyond simple flat panel displays, memory management, and more. Multiple cores are often needed, and so are hardware accelerators for compute-intensive functions. What’s needed from a microcontroller (MCU) in an IVI? A lot, but exactly what depends on the sophistication and mix of info and ‘tainment. ![]() In vehicle infotainment (IVI) systems are increasingly important and complex.
