Technology & Maintenance Council

Overview

The purpose of the Technology & Maintenance Council is to improve transport equipment, its maintenance and maintenance management. The Council develops Recommended Engineering and Maintenance Practices that are voluntarily adopted by fleets, OEMs and components suppliers.

The Council also conducts industry surveys and promotes the voluntary cooperation among designers and manufacturers of transport equipment and those who specify, purchase and manage such equipment.


Who We Support

The Technology and Maintenance Council supports the ATA technology & Engineering Policy Committee with research, analysis and policy development.

TMC IR 2015-3, Exploring the Potential for 48-Volt Commercial Vehicle Electrical Systems

Forty-eight volt electrical systems represent a great potential to save fuel and reduce greenhouse gas emissions. Idle stop-start technology can help save fuel while the vehicle is motionless, and torque assist can also be supplied to the engine for launch and low-speed momentary acceleration. Increased energy storage and recapture of brake energy is also possible through 48-volt electrical/electronic (E/E) technology, further improving on overall efficiency. In addition, there are other possibilities with the use of a 48-volt supply that would not be possible with a 12-volt battery in in a commercial motor vehicle (CMV), such as electronically controlled air-conditioning (A/C) compressors and fully electric power steering.

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.

TMC FT Position Paper 2014-1, Future Trailer Productivity: Increasing the Efficiency of Pre and Post Trip Inspections

Traditional methods for both pre- and post-trip inspections have existed for decades with few changes or improvements. Traditional tools and technology limit inspection effectiveness, add time to both the inspection and reporting, and contribute to the potential for errors and miscommunication of the resulting data. This paper explores technologies that may increase the efficiency of pre- and post-trip trailer inspections and provides a vision for future development of technologies and systems for that purpose.

TMC IR 2016-1, Battery Electric Vehicles in Light- & Medium-Duty and Specialty Truck Commercial Applications

A Class 1-6 commercial motor vehicle (CMV) powered solely by electricity is much different than a CMV powered by an internal combustion engine (ICE) or by hybrid electric vehicle (HEV) design. A battery electric vehicle (BEV) design includes storage only for its onboard battery capacity, not fossil fuel. The battery capacity has a direct impact on vehicle range and powered features. The electrical propulsion system requires a high voltage supply and significant current draw that dictates the capability and therefore the battery capacity. Unlike electric cars that can transport a relatively light load within a limited range, a commercial application relates to the operator’s ability to fulfill a customer’s expectations. Commercial BEVs have balanced design considerations that involve total vehicle cost, weight, energy storage capability, and lifecycle value. The primary consideration is the battery in which lithium-ion (Li-ion) technology has grown to be most popular for its design. Other considerations rely on the unloaded weight amount the CMV has compared to its maximum load weight amount dependent on distance, geographical terrain, duty cycle and any other specific industry segments that test its capabilities. End users must understand their own applications before changing from ICE design or HEV fleet units to fully electric.

RP 628C, Aftermarket Brake Lining Classification

The purpose of this Recommended Practice (RP) is to provide information for judging the performance of aftermarket brake linings on air-actuated foundation brakes, when performing the dynamometer test and vehicle stopping distance procedures in Federal Motor Vehicle Safety Standard (FMVSS) No. 121, Air Brake Systems, and lining supplier qualification information. Such information will assist fleet operators in choosing aftermarket brake linings that will perform adequately on typical combination (tractor/trailer) vehicles and single trucks.
