The R-Car H3 and R-Car M3 SoCs have been designed for in-vehicle infotainment (IVI) applications that deliver images, audio, and a variety of information from both in-vehicle and external sources to the driver. Toyota’s next-generation multimedia system will make its first appearance in the Lexus NX, scheduled for release in November 2021. These systems are planned to be installed in other Lexus- and Toyota-branded vehicles.
Toyota’s next-generation multimedia system incorporates a large-format, high-resolution, maximum 14-inch, wide touch display. The display area can be flexibly divided into sections and zoomed in and out, providing a combination of advanced functionality and convenience.
The system features voice recognition functions, such as quick start-up in response to voice commands, an automotive sound system, and an over-the-air (OTA) software update function.
Within these functions, Renesas’ R-Car SoCs provide the ability to import map information, images, and video input from users’ preferred devices, including smartphones, and connected applications to the large display. They also enable functions such as display touch controls, voice recognition via the microphone input, and audio output to multiple speakers.
In addition, a sophisticated built-in security function enables secure OTA software updates and provide advanced connected services powered by the SoCs’ outstanding computing performance.
As multimedia system functions vary based on the vehicle model, Toyota has implemented the R-Car H3 in systems for high-end models equipped with full functionality, and the mid-range R-Car M3 in other vehicle models. The R-Car Family is able to provide software compatibility across the product line, contributing to more efficient development when extending systems to a wide range of vehicle models. In addition, Renesas’ broad array of R-Car ecosystem partners offered support for its development.
“In order to meet users’ diversified needs in the CASE era, a new multimedia system was developed,” said Masato Kobayashi, Director of Connected System Development Division at Toyota Motor Corporation. “Two of our biggest challenges in realizing the leading-edge system was the efficient development while securing the necessary performance and making complex automotive software. Renesas’ R-Car SoCs are designed specifically for automotive applications, providing excellent performance and reliability, backed by a robust ecosystem – a combination that enabled us to create innovative multimedia systems.”
