R-Car E3 Renesas upgrades 3D auto display for automotive instrument clusters

Renesas upgrades 3D auto display graphics.

Using the tools, developers working with the R-Car system-on-chip (SoC) family can create applications, such as predictive safety infotainment applications that link dynamic data from the vehicle and the cloud in real time with algorithms developed based on big data in the cloud.

This enables out-of-the-box development of innovative applications instead of the traditional approach of simply connecting the vehicle to the cloud, making cloud services available in the vehicle.

Due to the unique challenges of managing vehicle data and the need to develop applications under conditions where in-vehicle testing is difficult or impossible, it has been difficult for software developers to leverage the cloud services that AWS provides through vehicle data at the edge, such as predictive driving support applications.

Renesas’’ new software development toolset makes it possible to generate new services that combine, in real time, vehicle data (e.g., the driving status and the state of the driver)s and cloud-based data (e.g., construction, congestion, or other road conditions) as well as weather reports and maps.

To link the cloud and the edge, Renesas has adopted AWS’ cloud services and the Greengrass for its software development tools.

The software development tools have been validated by both AWS Greengrass and AWS IoT core and have been tested to run on the R-Car Starter Kit under Automotive Grade Linux environment.

Combining 3D rendering with integrated audio DSP and other peripheral functions, the single-chip SoC supports instrument clusters as well as in-vehicle infotainment (IVI) systems with display audio and other capabilities.

The R-Car E3 is an upscale to the predecessor R-Car D3SoC for 3D graphics clusters, that brings enhanced 3D graphics rendering performance.

As part of the Renesas R-Car family, the new SoC also offers the functional safety and security functions that are essential for connected cars as the role of human-machine interface (HMI) becomes more important.

With these features, the R-Car E3 simplifies the task of developing robust systems capable of dealing safely with both malfunctions and cyberattacks.

The single-chip design enables the integration of a variety of systems, significantly reducing overall system development costs and achieving substantial space savings.

The R-Car E3 shares the scalability of the R-Car H3 and for integrated cockpits as well as the R-Car D3 for instrument clusters, establishing the highest level of software reuse.

Renesas partner companies with extensive experience in the instrument cluster field are ready to provide operating systems (OS) and HMI tools in addition to system integration support.

This will greatly reduce the development burden, extending software support to a wide range of vehicles, from the premium class, which currently features the high-end 3D graphics experience, to  entry-class vehicles where integrated systems and full graphics are expected to become mainstream.
