R-Car T2


The R-Car T2 is a system on chip (SoC) for in-vehicle camera networks that conforms to all four standards (IEEE802.1AS / IEEE802.1Qav / IEEE802.1Qat / IEEE1722) that make up the Ethernet AVB standard, and is capable of transmitting images at extremely low latency. This enables camera images to be shared with multiple systems while maintaining real-time performance, which can be used for various driver assistance systems such as surround view monitoring and obstruction detection.

  • Lower power consumption and more compact size help reduce the size of the camera housing (countermeasure against heat) in order to minimize negative effects on automobile design
  • Next-generation Ethernet helps reduce amount of cables to reduce vehicle weight and space requirements
  • H.264 encoder realizes high-quality, low-latency image transmission that helps improve visibility
  • Low-latency performance is realized by optimization of proprietary system

Block Diagram of Module

  • Ethernet AVB 1.0-conformant
  • Built-in independently developed H.264 encoder; < 1 ms low-latency transmission of high-quality, high-definition images
  • Connects to 1.3 Megapixel image sensor SoC
  • Ultralow power consumption: 40 mW (typ.); reduces device-generated heat issues
  • 6-mm-square small package allows size of camera module to be reduced
  • Guaranteed connectivity with other R-Car devices
