North American CAV Performance Data StandardWP-00157/22/2026
As the deployment of connected and automated vehicles (CAVs) expands, the need for a consistent, cross-industry approach to performancerelevant CAV data exchange is becoming more pressing. Vehicle developers, infrastructure owners and operators (IOOs), and technology providers generate and consume data that support safety, mobility, and operational efficiency, yet much of the data remains fragmented, inconsistently formatted, and difficult to reuse across systems. To address these gaps, the Society of Automotive Engineers (SAE) and the Canadian Standards Association (CSA) convened a multi-stakeholder workshop on November 3, 2025, with participants representing original equipment manufacturers (OEMs), automated driving system (ADS) developers, state and local agencies, standards bodies, and technology partners. The workshop focused on identifying challenges, clarifying needs, and outlining a path toward a North American CAV Performance Data Standard. Key themes from the workshop included: -A shared data language is needed to support safe and interoperable CAV operations. -The current ecosystem lacks consistent formatting, labeling, and visibility regarding who produces and consumes data. -A “start small, iterate, and scale” approach is needed, beginning with well-defined use cases such as school zones or baseline work zones. -Progress depends on technical harmonization and governance structures that build trust and support sustained coordination. This white paper summarizes the key findings and outlines a practical approach to developing a Version 0.1 base-layer data standard that can support measurable progress in 2026 and beyond.

In this study, an efficient method for concurrent thermomechanical performance and weight optimization under modal constraints is proposed to address the coupled design challenges of thermomechanical characteristics (thermal capacity, thermal deformation, and modal) and structural weight in straight-ribbed brake discs. Based on high-fidelity computer-aided engineering (CAE) simulations of brake disc thermomechanical behavior, a neural network (NN)-based surrogate model and a ResNet-guided geometric feature recognition (RGFG) model for automatic modality recognition were developed, and integrated with a particle swarm optimization (PSO) framework for optimal solution exploration. When applied to a passenger vehicle brake disc case study, the surrogate model of NN demonstrates remarkable accuracy: it shows more than 95% agreement with the CAE results in thermal capacity prediction, the prediction accuracy of thermal deformation exceeds 90% compared to CAE results and 83.4% compared to test result, thereby validating the method’s effectiveness. Compared with conventional CAE approaches, the surrogate model of NN achieves a subsecond prediction speed, significantly reducing computational costs. The surrogate model of RGFG achieves a test accuracy exceeding 95%. Furthermore, the proposed optimization framework offers valuable insights for the inverse design of brake discs.

The impact of a titanium nitride (TiN) coating by the cathodic arc deposition (CAD) technique on a 316L stainless steel (SS) 316L substrate is examined in this experimental work. The X-ray diffraction study showed that TiN made the osbornite phase grow in the coated specimen. The SS 316L sample had a hardness of 217.66 HV, and the samples with CAD coatings were five times harder than the uncoated disc. The wear test was conducted using a pin-on-disc tribometer under dry and wet conditions at loading conditions of 2 N, 4 N, and 6 N with the counterpart of grade 5 titanium alloy (Ti6Al4V). Wear resistance improved significantly, with the wear rate decreasing markedly after coating compared to the uncoated sample. The wear morphology of the wear on the contact surfaces was identified by SEM analysis of the images. The biocompatibility of the ceramic-coated SS 316L sample with the normal cell line was proved by a cell viability test. The demand for SS 316L and the use of CAD coatings to reduce friction and wear in bio-implant applications were the main topics of the current study.

The proposed Digital Mesh/Fabric concept builds upon the Digital Thread Framework (refer to AIR7161) by representing the interconnection of multiple digital threads across multiple data stores, logical organizing segments, and product life-cycle stages. Unlike a single digital thread, which follows a linear or sequential flow of data utilization through a product life cycle, the Digital Mesh/Fabric forms a complex mesh of n-dimensional interconnected digital threads, allowing for greater value creation, flexibility in data utilization, scalability, and integration.

This SAE Recommended Practice was developed primarily for gasoline-powered passenger car and truck applications to interface vapor recovery systems, but it may be used in diesel, marine, industrial, and similar applications where a nozzle is required for filling. The zones cover nozzle spout access and handle clearance to a refilling port. In addition, this recommended practice includes a design window for nozzle manufacturers to develop with.

The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide the sample selection and endurance time test procedures for SAE Type II, III, and IV aircraft deicing/anti-icing fluids, required for the generation of endurance time data of acceptable quality for review by the SAE G-12 Holdover Time Committee. The related standard ARP5718 provides the process by which endurance time data is converted to holdover times for publication by regulators and subsequent use by aircraft operators.

This procedure measures the resistance to radiant heat flow of insulating materials in sleeve, tubing, or tape (collectively referred to as “sleeve”) form. The sleeve’s effectiveness (SE) is determined by measuring the difference in surface temperature of a flat black, single-diameter ceramic cylinder with and without the standard diameter sleeve at the specified temperature, position, and distance from the radiant heat source.
