Vehicle Control Unit

Overview

The Vehicle Control Unit (VCU) solution facilitates the implementation of a Software Oriented Architecture (SOA) or Software Defined Vehicle (SDV). The necessary interfaces such as standard and Gigabit Ethernet (GbE) are present to support zonal architecture by OEM.

Additionally, in entry-level/commercial vehicles, this VCU can act like a central compute/gateway, as the RH850/U2A automotive-control MCU device has sufficient performance headroom with multi-core architecture compliant with Functional Safety (FuSa) ASIL-B to ASIL-D.

System Benefits​:

  • Hardware design files and sample software are available.
  • A wireless communication board (REIN-WCB-V1) can be added to this solution enabling connected vehicle technology including 4G/GPS/Wi-Fi/Bluetooth® Low Energy (LE).
  • "No Wait" Over-the-Air (OTA) updates supported by the RH850/U2A MCU.
  • The onboard embedded Multi-Media Card (eMMC) provides Large Storage for various use cases.
  • Passenger and commercial vehicles
