HMI Design for In-Vehicle Infotainment Systems

The in-vehicle infotainment system is a combination of in-car systems that provide entertainment and vehicle information. It primarily offers navigation systems, music and video streaming, entertainment systems (such as games, TV), and calling functions. It is also the human-machine interaction (HMI) center of the automotive electronic system and serves as the main control center of modern vehicles.

Function Control Center

The in-vehicle infotainment system (IVI system) not only serves as an in-car entertainment medium but also becomes the control center for the active and passive safety functions of smart vehicles under the development of automotive intelligence, providing various wireless and wired transmission solutions to achieve vehicle intelligence.

In addition to the original high stability and durability of automotive electronics, the demand for external multimedia entertainment, vehicle networking (VoT), intelligent interactive resources, and the introduction of AI for IVI systems is gradually increasing.

Interface Experience

The technological integration of in-vehicle multimedia terminals, using touch screens instead of mechanical buttons for control, has become mainstream, focusing on human-machine interface interaction experience. Design considerations from the user experience perspective provide rich visual effects.

Main Features

Communication Technology

It is supported by various communication technologies, including mobile networks (LTE-A / LTE / UMTS / GSM), Bluetooth, WLAN, digital/audio broadcasting, and voice control, making communication technology integration more complex. Interconnection and communication between network and electronic system devices.

Characteristics

Based on the different operating system kernel mechanisms, optimization for quick device startup can meet the needs of various scenarios in automotive electronics. For example:

Using QNX to provide software upgrade services, the system can be safely and reliably upgraded automatically when a new software version is detected on the platform, integrating various navigation applications.

Development Trends

As the amount of information processing and display continues to increase, the future in-vehicle infotainment systems need to adopt powerful and flexible hardware solutions with efficient graphics capabilities and rich interfaces, including the use of navigation systems or high-quality audiovisual enjoyment. In the future, developments will move towards high-speed CPU processing, high-speed wireless communication, and high-resolution image rendering to provide faster and more diverse rich audiovisual entertainment experiences.
