Future Truck Position Paper 2018-5: Recommendations Regarding Dynamic Tire Inflation for Commercial Vehicles

Current practice for tire inflation pressure maintenance in the commercial vehicle fleet does not account for varying load, speed and environmental operating conditions actually experienced by the tire and vehicle. TMC recommends development of an integrated tire inflation pressure control system that can compensate for these factors and provide an automated means of inflating and deflating each tire to match the conditions encountered. This paper discusses the capabilities needed in such technology to provide value to trucking companies and how the technology could be successfully integrated into fleets.

Future Truck Committee Position Paper: 2018-3; Automatic Monitoring of Electrical System Health

TMC’s Future Truck Committee charged its Sensor Enhanced Maintenance Task Force to evaluate and state a position on the feasibility of automatic monitoring of electrical system health. The finding of that task force is that automatic monitoring of electrical system health is achievable by combining onboard circuit analysis with Testing for Statistical Significance (TSS). When paired together, these two fundamentally sound sciences quantify the state of health (SOH) for batteries, alternators, starters, and electrical cables. The use of the SAE J1939 communication network allows for downloading of data, scheduling of maintenance and integration with fleet management systems.

TMC Future Truck Position Paper 2018-2: Recommendations Regarding Future Brake System Air Line Monitoring

Recent advancements in sensor technology are enabling real-time monitoring of system performance and readiness in heavy-duty vehicles. ATA’s Technology & Maintenance Council (TMC) recommends that manufacturers leverage this new technology to develop a more accurate means of identifying slow leaks in air brake lines; thus improving driver awareness of developing brake system failures, and reducing the frequency and severity of thermal incidents (i.e., truck fires).

TMC Future Truck Position Paper: 2017-4, Recommendations Regarding Multi-Voltage Vehicle Electrical Systems

With the rising demand for improvements in efficiency and power availability, efforts are underway to incorporate higher voltages into the electrical systems of heavy-duty commercial motor vehicles. Throughout this effort, it is important that safety, reliability, and compatibility with equipment currently in use, be maintained. This paper, developed by TMC’s Electrical/Electronic Systems Task Force, under the auspices of the Council’s Future Truck Committee, serves to further outline these expectations.

TMC Future Truck Position Paper: 2017-3, Performance Expectations for Zero-Pressure Commercial Truck Tires

The Future Tire Durability and Reliability Task Force — working under the auspices of TMC's Future Truck Committee — was tasked with exploring and identifying key factors related to the adoption of zero-pressure tires in commercial transportation service. Accordingly, the Task Force developed this position paper to define future features and expectations for zero pressure commercial tires in terms of product performance, maintainability, reliability, durability, serviceability, environmental and educational issues. This document provides the industry with an overview of what will be necessary for trucking companies to integrate this new technology into their fleets.

TMC Future Truck Position Paper: 2017-2, Hydrogen Fuel Cells for Heavy Trucks

The application of hydrogen fuel cell technology to commercial trucks has received a great deal of attention lately, especially following the announcement of at least one manufacturer’s plans to introduce a hydrogen-hybrid electric model for purchase by the year 2020 and a second OEM’s planned test at the Port of Los Angeles. As might be expected, this interest has prompted many questions by both fleet and supplier professionals. TMC's Future Truck Committee charged its Future Alternate Propulsion System Task Force to explore the issue and this paper represents its findings as to whether the technology is ready for commercial use, using a “pass/fail” scale.

Future Truck Position Paper: 2017-5, Recommendations Regarding Future Trailer Energy Efficiency and Performance

Significant opportunities exist to collect or harvest energy using systems or technology on the trailer for improving the energy efficiency of the vehicle combination. Two such sources, solar energy collection and regenerative braking are being investigated in earnest and are in the early stages of commercial development. The purpose of this paper is to facilitate increased performance and energy efficiency for trailers. Additionally, this paper offers goals for energy efficiency improvement related to the design and operation of semi-truck trailers to encourage and accelerate development of appropriate technology.

TMC Future Truck Position Paper: 2017-1, Future Energy Sources for Commercial Vehicles

Today’s heavy-duty truck manufacturers are increasing their focus on more efficient management of all types of energy in commercial vehicle (e.g., combination vehicle, straight truck, etc.). This position paper explores industry efforts at attaining alternate energy sources and what steps should be taken to implement such alternatives successfully for commercial vehicle operations. TMC believes the next step in vehicle energy conservation is to investigate the usage of the fuel energy once it is burned and develop strategies for efficient recovery and subsequent usage where possible and feasible. At the same time, this effort should include using ‘free’ energy, specifically solar, as part of the overall energy mapping process. The time is now to begin laying out an electrical system architecture that will accommodate the energy efficient tractor and trailer of the future. TMC's study groups and task forces should play a leading rolle in developing this architecture, working with other industry groups and organizations as needed.

TMC FT Position Paper 2016-1: Dynamic Adjustment of ‘Wheel Rotations Per Mile’ Via GPS-ECU Comparison

The ability to refine wheel-based road speed calculations through the adjustment of wheel rotations per mile via global positioning satellite (GPS) input is a desirable feature that does not yet exist for heavy-duty commerical motor vehicles (CMVs). This technology, which would dynamically adjust rotations per mile to account for tire wear, could improve speedometer accuracy and fuel economy reporting (as reported by the engine electronic control unit or (ECU). It also has the potential, if wheel-end sensors are employed, to report current remaining tread depth and the need for tire replacement due to wear. This technology would compare vehicle distance travelled as measured by both a GPS-enabled device and the vehicle ECU, and should a reasonably significant difference exist, the ECU’s “wheel rotations per mile” parameter would be automatically adjusted accordingly, to compensate for tire wear.
