At the American Trucking Associations 2021 Technology & Maintenance Council Fall Meeting & Transportation Technology Exhibition in Cleveland last month, the first face-to-face convocation in 18 months was full of energy. To maintain momentum, TMC expects the ability to carry out several research projects under an agreement with the FP Innovations / PIT Group, which has been postponed due to the impact and limitations of COVID. This partnership allows TMC to bring its own research projects directly to the PIT Group, including access to on-track testing capabilities.

The TMC aims to carry out two projects in 2022 and will need to carry out this research through next fall’s conference, through personnel and equipment contributions, and basic financial support. We plan to obtain support from various industries. By the end of this year, TMC aims to gather the essential contributions to keep the project on track.

The first project, developed by TMC’s S.2 Tire & Wheel Study Group, reproduces the on-orbit assessment of the impact of overall vehicle alignment on fuel consumption in tractor and trailer combinations, first studied by Goodyear Tire & Rubber Co. .. .. In 2008, it was documented in the report “Factors Affecting the Fuel Economy of Trucks”. The latest TMC assessment uses the same protocol to examine combination vehicles equipped with currently available aerodynamic devices to determine the impact of misalignment. Energy consumption is the most important road operating cost, so even small increments are added up after traveling miles.

TMC will conduct on-track testing of Class 8 trucks with prototype EMB to demonstrate performance in compliance with Federal Motor Vehicle Safety Standards. (TMC)

These test methodologies make use of some of TMC’s recommended practices. TMCRP1102A, TMC Fuel Consumption Test Procedure — Type II and TMC RP 642B, Full Vehicle Alignment: Recommendations for maximizing the life of tires and alignment-related components.

PIT Group personnel will conduct the assessment at Transport Canada’s Automotive Testing Center in Blainville, Quebec. First, a baseline is set and the fuel consumption from the RP 1102A procedure is compared on a control vehicle with the same specifications as the test combination vehicle. In both cases, the entire vehicle has been carefully adjusted according to RP642B. Intentional misalignment is then introduced into the test vehicle for continuous test execution to allow structured comparisons with Goodyear’s 2008 test results.

TMC will coordinate the project with the PIT Group’s annual Energotest in June 2022. This is done to achieve the most cost-effective use of resources by using the same equipment and equipment for both assessments. TMC is seeking financial support from the industry to cover these costs and has prepared a project prospectus for potential contributors.

The second project will carry out on-track testing of a Class 8 truck equipped with a prototype electromechanical braking system (EMB) to demonstrate the performance of the air brake system in compliance with Federal Motor Vehicle Safety Standards. This project completes the second phase of TMC’s research into the potential of EMB systems used in the truck industry. TMC’s Future Truck Committee considers the industry to consider the potential benefits of different types of electronically controlled braking systems (ECBS) that employ control modules at the wheel ends in either the Air Disc Brake (ADB) application or the EMB. I proposed it first. Pneumatic brake caliper operation.

TMC’s Chassis & Brake Systems Study Group (S.6) will present a technical session at the autumn conference on the possibility of adopting new technologies in commercial vehicle braking systems, including discussions on both ECBS and EMB.

The first phase of the EMB project, which evaluated the development of EMB by partner brand suppliers and brake system suppliers, was reported at the 2020 Atlanta Annual Meeting, the last pre-pandemic TMC face-to-face event. rice field.



The PIT Group surveys and evaluates EMB Technology’s 43 Original Equipment Manufacturers (OEMs), with 16 OEMs supporting TMC’s work in the Future Truck program. In particular, the focus is on the future of commercial braking and OEM involvement in the development of electromechanical brakes for Class 8 trucks. Using the information provided, the PIT Group evaluated the “design state” of each technology based on the current data of the available technologies. This includes progress towards prototyping and technical challenges, limitations and obstacles expected or encountered. ..

The PIT Group has discovered that a variety of manufacturers are involved in EMB research and development, from pre-prototype design to prototype testing and road evaluation. In general, the only EMB under development may be disc brakes. These can be used without major changes to existing axles, but larger vehicles require a 24-volt or 48-volt power supply system. Despite the unique differences of each OEM’s electromechanical braking system, it claims to be superior to current pneumatic braking in terms of increased wheel end diagnostics and shorter stopping distances.

In this study, Phase 2 of the project is possible to justify the need to change the regulatory framework to allow operational use of EMB, especially when working with a mixed pneumatic and EMB architecture. I have identified the sex. The TMC believes that some OEMs have developed prototype systems to enable in-orbit evaluation of performance, and as a result, the council has worked with the PIT group to carry out a preliminary set of test procedures. bottom.

TMC is seeking the contribution of these EMB prototypes, which will be first installed on Class 8 straight trucks, to test compliance with federal standards for braking system performance. The goal is to determine if they perform at least as well as the pneumatic systems that are currently performing. Assuming these commitments are coming soon, TMC is considering scheduling track testing in the second half of 2022.
