Renesas Electronics, a supplier of semiconductor solutions, has announced that its R-Car H3 and R-Car M3 system-on-chips (SoCs) have been adopted by Toyota Motor Corporation for the latter’s next-generation multimedia systems.

The Renesas R-Car H3 and R-Car M3 SoCs are 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 in a safe and convenient manner. Toyota’s next-generation multimedia system will make its first appearance in the Lexus NX, before being installed in other Lexus- and Toyota-branded vehicles.

Toyota’s next-generation multimedia system incorporates a large-format, high-resolution, maximum 14″, 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’s R-Car SoCs provide the ability to smoothly 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, the SoCs’ sophisticated built-in security functions enable secure OTA software updates and provide advanced connected services powered by the SoCs’ good 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 provides software compatibility across the product line, contributing to more efficient development when extending systems to a wide range of vehicle models. In addition, Renesas’s broad array of R-Car ecosystem partners offered support for its development.

“In order to meet users’ diversified needs in the CASE [Connected, Autonomous, Shared and Electric] era, a new multimedia system was developed,” said Masato Kobayashi, Director of Connected System Development Division at Toyota. “Two of our biggest challenges in realising the leading-edge system was the efficient development while securing the necessary performance and making complex automotive software. Renesas’s 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.”

“I am delighted that Renesas’s R-Car SoCs are part of Toyota’s next-generation multimedia system, and that Lexus vehicles equipped with this functionality are coming to the market,” added Takeshi Kataoka, Senior Vice President and General Manager of the Automotive Solution Business Unit at Renesas. “I am excited that next-generation cockpit systems offering an intuitive user experience will be available in a wide range of car models moving forward, and that vehicles offering an enhanced user experience with security and convenience will become available worldwide.”
