About automotive UX and HMI systems for in-vehicle infotainment

Automotive human-machine interface (HMI) systems are designed to enable drivers to interact with their vehicles without being distracted. HMI can establish a more natural interaction between humans and machines through touchpads, buttons, or speech systems. The increasing demand for connectivity solutions, low-cost HMI software, and enhanced user experience (UX) has made HMI solutions like head-up displays (HUD), rear-seat entertainment systems, steering-based controls, instrument clusters, and voice command systems popular in the automotive market.

Infineon, as a leading automotive semiconductor manufacturer, offers a wide range of solutions that support seamless and secure communication between the driver and the vehicle. They provide high-performance microcontrollers, memories, HMI controllers, and automotive-grade security solutions for automotive infotainment systems. In addition, their automotive radar systems help improve the vehicle's situational awareness and driver assistance features. Overall, Infineon's solutions help automakers provide a more natural and intuitive HMI system that ensures safety, comfort, and convenience for drivers.

Automotive UX and HMI applications and use cases

Instrument cluster, head-up display (HUD), head unit, and cockpit domain controller, or high-performance cockpit computer, are the central control and user interface systems that manage and deliver driving information and entertainment for drivers and passengers, all through audio and video interfaces, control elements such as touch screen displays, button panels, voice commands, and more.

Telematics plays an important role in autonomous driving and service-over-air updates for vehicle safety and security. Use cases for telematics control units include emergency call (eCall), roadside assistance, vehicle fleet management and maintenance, vehicle-to-cloud (V2X), vehicle-to-vehicle (V2V), and vehicle-to-infrastructure (V2I) communication.

The automotive in-cabin monitoring system (ICMS) is a system that monitors the interior of a vehicle to ensure the safety of occupants. It typically consists of sensors that can detect various factors such as passenger presence, seat belt usage, and even driver fatigue.

High-performance cockpit controller
Telematics control unit (TCU)
Infineon's broad IC portfolio covers key automotive UX and HMI applications

Computing:?The TRAVEO? T2G MCU family offers high performance (up to dual Arm? Cortex?-M7, 1500 DMIPs), wide scalability (memory density and package line-up), best-in-class energy efficiency (deep sleep mode: 35 ?A, hibernate mode: 5 ?A), ASIL-B functional safety, and an integrated hardware security module (HSM).

Sensors:?The PSOC? automotive family offers in-cabin touch solutions from a single source. Automotive-qualified MEMS microphone sensors provide supreme audio reception in dynamic environments.

Connectivity and communication:?Broad Wi-Fi and Bluetooth? portfolios support various in-cabin wireless connections; CAN, LIN transceivers, and system basis chip (SBC) families connect the head unit to in-vehicle networking.

Power supply:?OPTIREG? PMIC, linear, and switcher devices support reliable power supply; USB Type-C PD (power delivery) controllers support fast charging (up to 100 W) with best-in-class interoperability and compliance with all kinds of mobile devices.

Storage:?A broad automotive-qualified NOR flash, SRAM, and F-RAM portfolio provides safe, secure, and reliable data storage.

Automotive USB charging
High-bandwith communication with Ethernet solutions

Increasing personalized user experience for cockpit applications will be the differentiating factor for future vehicle generations. Therefore applications such as center information display or cockpit controller demand fast, reliable, and scalable in-vehicle communication to support infotainment system updates, device integration or multi-display architectures. Infineon's BRIGHTLANE? Ethernet solutions, including PHYs, switches, and bridges, are tailored for these high-performance requirements, offering high bandwidth and low-latency networking capabilities.

Together with our leading automotive MCU portfolio we support network solution speeds from 100 Mbps to 10 Gbps and meet today's and tomorrow's increasing communication demands.? In parallel, our BRIGHTLANE? Ethernet solutions allow minimum power consumption while providing maximum flexibility. This is closely tied to a superior software stack that enables application layer focused development.

Moreover, Infineon's Ethernet solutions simplify the integration of zonal and centralized vehicle architectures, enabling cockpit benefits such as fastest data transfer with centralized graphic processing in a SoC (System-on-Chip).
