The Recreation Vehicle Industry Association commissioned an Economic Impact Study on the RV industry, released on June 7, 2016. The study found that the RV industry contributes about $49.7 billion in economic output or 0.28 percent of the Gross Domestic Product. Through its production and distribution linkages, the industry impacts firms in 426 of the 440 sectors of the United States economy.
Nationwide, the industry is responsible for 216,170 jobs, both directly and inderectly, creating an economic impact of $37.5 billion. The full study results, along with each individual state and congressional district's economic impact is available on the website by clicking here .

NVIDIA unveiled details of its functional safety architecture for NVIDIA DRIVE, its autonomous vehicle platform at the Consumer Electronic Show in Las Vega, Nevada, Wednesday.
The artificial intelligence platform uses redundant and diverse functions to enable vehicles to operate safely, even in the event of faults related to the operator, environment or systems, according to a company press release. The NVIDIA DRIVE architecture enables automakers to build and deploy self-driving cars and trucks that are functionally safe and can be certified to international safety standards, such as ISO 26262.
“Safety is the most important feature of a self-driving car,” said Jensen Huang, founder and chief executive officer of NVIDIA. “It is imperative that it operate safely, even when things go wrong. NVIDIA’s investment into this functional safety platform is one of the most important ones we’ve ever made, and it provides a critical ingredient for automakers to bring self-driving cars to market.”
NVIDIA DRIVE provides a holistic safety platform that includes process, technologies and simulation systems, as described below:
• Process: Sets out the steps for establishing a pervasive safety methodology for the design, management and documentation of the self-driving system.
• Processor Design and Hardware Functionality: Incorporates a diversity of processors to achieve fail operation capabilities. These include NVIDIA-designed IP related to NVIDIA Xavier covering CPU and GPU processors, deep-learning accelerator, image-processing ISP, compute-vision PVA, and video processors – all at the highest quality and safety standards. Included are lockstep processing and error-correcting code on memory and buses, with built-in testing capabilities. The ASIL-C NVIDIA DRIVE Xavier processor and ASIL-D rated safety microcontroller with appropriate safety logic can achieve the highest system ASIL-D rating.
• Software: Integrates world-leading safety technology from key partners. NVIDIA DRIVE OS system software integrates BlackBerry QNX’s 64-bit real-time operating system, which is ASIL-D safety certified, along with TTTech’s MotionWise safety application framework, which encapsulates each application and isolates them from each other, while providing real-time computing capability. NVIDIA DRIVE OS offers full support of Adaptive AUTOSAR, the open-standard automotive system architecture and application framework. The NVIDIA toolchain, including the CUDA compiler and TensorRT, uses ISO 26262 Tool Classification Levels to ensure a safe and robust development environment.
• Algorithms: The NVIDIA DRIVE AV autonomous vehicle software stack performs functions like ego-motion, perception, localization and path planning. To realize fail operation capability, each functionality includes a redundancy and diversity strategy. For example, perception redundancy is achieved by fusing lidar, camera and radar. Deep learning and computer vision algorithms running on CPU, CUDA GPU, DLA and PVA enhance redundancy and diversity. The NVIDIA DRIVE AV stack is a full backup system to the self-driving stack developed by the automaker, enabling Level 5 autonomous vehicles to achieve the highest level of functional safety.
• Virtual Reality Simulation: A self-driving car is an extremely complex system with state-of-the-art technologies. Proving that the system does what it is designed to do —captured by the term SoTIF, or safety of the intended functionality — is a great challenge. And it must do so in a wide range of situations and weather conditions. Road testing is not sufficiently controllable, repeatable, exhaustive or fast, so a realistic simulation environment is essential. NVIDIA has created a virtual reality simulator, called NVIDIA AutoSIM, to test the DRIVE platform and simulate against rare conditions. Running on NVIDIA DGX™ supercomputers, NVIDIA AutoSIM is repeatable for regression testing and will eventually simulate billions of miles.
