Overview

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, it 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 a 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 the amount of cables, which reduces 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 a proprietary system
