Overview

Description

The R-Car M3e can be used in a wide range of automotive applications requiring medium-class computing, including for example In-Vehicle Infotainment, low-end integrated cockpit, connected gateway, central server.
A 2GHz version (M3e-2G) is also available, providing increased CPU power.
The R-Car M3e(-2G) is fully software-compatible with the R-Car H3e(-2G), so existing software resources can be reused effectively.

Features

  • Compliant with ISO 26262 (ASIL-B) functionality safety standard for automotive
  • Optimized functions and performance enable use in a wide range of applications
  • Compatibility with previous products enables use of the existing ecosystem and access to over 180 R-Car Consortium partners

Applications

Applications

  • Medium-class automotive computing systems

Integrated Automotive Cockpits

Save cost and design effort in functional safety with Renesas scalable R-Car roadmap, providing a robust freedom of interference between the Cluster and Android system.

Video Transcript

My name is Guido Hilker, I'm from Renesas Electronics and today I talk about integrated cockpits.

The challenge of integrated cockpit is to run cluster, navigation and center stack on one ECU. Some OEMs have already started such integration with the target to save cost and still offer an attractive solution with a nice look and feel.

The demo is running on R-Car M3N and is showing a low cost integrated cockpit solution. In the middle, an Android system is running, showing a navigation application which could be also a smartphone replication. In parallel, the embedded real-time CPU, which is separated by system architecture, is drawing a full graphics cluster using the 2D drawing engine.

For integrated cockpit, Renesas offers a scalable R-Car product lineup. And also robust freedom of interference between the cluster system and the Android system is achieved by separation of hardware. And therefore the efforts for functional safety can be greatly reduced, which saves cost and effort. Finally, the real-time system will boot faster, offering an early availability of the cluster function, rearview camera or audio.
