Tucson will release a domain controller based on NVIDIA DRIVE Orin SoC chips for L2+ to L4 autonomous driving

The autonomous driving technology company TuSimple announced today that it has launched a domain controller product (TDC – TuSimple Domain Controller) based on NVIDIA DRIVE Orin SoC chip design and development, which is expected to begin mass production and delivery by the end of 2023.

According to reports, this product is an autonomous driving computing platform self-developed by Tucson to meet the vehicle specification level. It integrates sensor input, high-performance computing, vehicle control unit (VCU) and automatic driving application software, and can meet the requirements of L2+ to L4 automatic driving. Compute needs.

After multiple rounds of software and hardware system iterations and actual road tests, the B sample product has been delivered to customers for testing and verification, and the C sample is expected to start shipping in the second quarter of 2023. The mass-produced version will cooperate with internationally renowned OEM manufacturers and is expected to be delivered in the Chinese market by the end of 23, and is expected to land in the European and American markets one after another.

TDC can realize a series of autonomous driving solutions by seamlessly cooperating with sensors of different configurations and TuSimple’s automatic driving application software.

The summary is as follows:

  • ADAS: L2+ and conditional L3 ADAS solutions for commercial vehicles, improving road safety and fuel efficiency
  • Perception fusion module: software and hardware modules integrate multiple sensors to provide OEM customers with highly customizable and low-cost full-stack perception solutions
  • L4 level automatic driving: main control + redundant computing unit, providing computing power for L4 level automatic driving system

TuSimple said that unlike most of the development models based on NVIDIA modules in the market, TDC conducts customized development based on NVIDIA Orin system-level SoC chips, which can provide more fine-grained scene technology customization capabilities, and compared with the module development model Costs are down about 25%.

For example, TDC will support two heat dissipation schemes of air cooling and water cooling, and provide two kinds of power supply support of 12V and 24V. The combination of different schemes allows customers to choose more flexibly. It is worth mentioning that the TDC 24V power supply scheme can meet the power supply requirements of domestic heavy trucks, and it is also a unique power supply design scheme for Tucson in the future.

In terms of underlying software, TDC products support AUTOSAR Classic Platform adaptation and AUTOSAR Adaptive Platform integration, and provide SOTA and FOTA solutions, with built-in CMOS sensor modules and lidar drivers common in the market.

The design and development of TDC products adopts commercial vehicle design standards, which are more stable and safer than passenger vehicles. TDC adopts the ASIL-D level QNX operating system and integrates the ASIL-D level Infineon TC397 chip. The overall functional safety level of the product reaches the ASIL-D level.
