Connected Android-Based Vehicle Instrument Cluster

Overview

Description

Automotive cockpits are vital for driver safety and experience, offering centralized controls and displays for key vehicle functions. With advancements in automotive technology, there is a growing demand for enhanced user experience, seamless connectivity, safety, and customization in vehicles.

This connected Android-based vehicle instrument cluster offers extensive wireless connectivity options, including Wi-Fi, Bluetooth®, Bluetooth Low Energy (LE), LTE, and GPS. It supports up to three display connections, providing functionalities such as navigation, media control, vehicle status monitoring, and real-time information.

System Benefits​:

  • Features the R-Car M3e-2G system-on-chip (SoC) with 2xCA57, 4xCA53, and 1xCR7 cores for high performance, efficiency, and versatility in real-time processing tasks.
  • Dual-OS setup with Android for infotainment and FreeRTOS for cluster applications optimizes resource utilization and enhances system stability and reliability.
  • A streamlined, hypervisor-less system simplifies design and reduces potential failure points.
