Motor Vehicle Measurement Certification Standard

This recommended practice applies to any vehicle manufacturer that chooses to publish vehicle dimensions and specifications that may influence customer purchase decisions. The intent is to define standardized vehicle dimensions that reflect showroom conditions and / or dimensions experienced during purchase conditions and also include published dimensions used in marketing / advertising materials irrespective of communications media that influence purchase decisions This document also provides a method to certify OEM and 3rd party compliance with recommended SAE and ISO measurement practices for vehicle dimensions commonly reported publically for marketing and competitive vehicle analysis

Maturity Level and Variant Validation of Mechatronic Systems in Commercial Vehicles

Driver assistance systems (e.g. the emergency brake assist Active Brake Assist2, or ABA2 for short, in the Mercedes-Benz Actros) are becoming increasingly common in heavy-duty commercial vehicles. Due to the close interconnection with drivetrain and suspension control systems, the integration and validation of the functions make the most exacting demands on processes and tools involved in mechatronics development.

Data Driven Testing for HIL Systems

The amount of software, computation and logic embedded into the vehicle systems is increasing. Testing of complex real time embedded systems using Hardware in Loop (HIL) simulations across different vehicle platforms has been a challenge. Data driven testing enables a qualitative approach to test these complex vehicle systems. It consists of a test framework wherein the test logic and data are independent of the HIL test environment. The data comprises variables used for both input values and output verification values. This data is maintained in a database or in the form of tables. Each row defines an independent test scenario. The entire test data is divided into three categories, High, Medium and Low. This feature gives the advantage of leveraging the same set of test data from Unit Level Testing phases to the Integration Test phase in the V-Cycle of software development. A data driven test approach helps the reuse of tests across vehicle platforms.

Occupant and Vehicle Responses in Rollovers

During the past decade, there has been a steady increase in studies addressing rollover crashes and injuries. Though rollovers are not the most frequent crash type, they are significant with respect to serious injury and interest in rollovers has grown with the introduction of SUVs, vans, and light trucks. A review of Occupant and Vehicle Responses in Rollovers examines relevant conditions for field roll overs, vehicle responses, and occupant kinetics in the vehicle. This book edited by Dr. David C. Viano and Dr. Chantal S. Parenteau includes 62 technical documents covering 15 years of rollover crash safety, including field crash statistics, pre- and rollover dynamics, test procedures and dummy responses.

Accessibility of Buses for Maintenance

A SURVEY of 30 typical bus operating companies was made by the author to get a representative opinion regarding the accessibility of present-day buses for servicing and maintenance. After pointing out the large number of complaints about inaccessibility that these companies had, he discusses their needs under the following classification: 1. Accessibility for nightly service operations. 2. Accessibility for scheduled inspection, testing, and adjustment work. 3. Accessibility for removal of complete units. 4. Accessibility within major units themselves.

Gear Testing Methods For Development of Heavy-Duty Gearing

SEVERAL methods of testing the gears used on heavy-duty transmissions are discussed here. An important feature of these tests, according to the authors, is the degree to which they correlate with actual field experience. In this connection they emphasize that laboratory tests will never completely replace field tests, however, because 100% correlation between the two types of tests can never be achieved. The authors explain that the laboratory tests should, nevertheless, allow new gear designs to be developed that are closer to being right the first time and that require less time to correct any failures that show up in the field.
Technical Paper


THE first step toward longer valve life as described in this paper, is a careful disassembly and inspection of the engine. Good judgment and care should then be used in correcting or replacing those parts that are scaled or damaged through previous usage. When the engine is disassembled and inspected after a run, it may be found that some of the worn parts are still within wear limits that can be tolerated. The valve stem tip will show the first sign of tappet-screw or rocker-arm wear, which, if serious, will lead to erroneous tappet clearance readings. Regrinding may accomplish the correction. Extremely worn bushings or scuffed tappets should be replaced. Valve guide wear should be carefully checked because it affects the overall valve temperature, the increase in clearance leading to less heat conductivity. The next consideration is the valve spring, for which the authors suggest the checking of five wear points.

The Traction of Pneumatic Tractor Tires

THE cooperative tractor tire tests described in this paper were discussed originally at a meeting of the Society several years ago. The tractor engineers present at the discussion suggested to the tire engineers that there was need for a cooperative test program to determine the efficiency of the various tire sizes over a range of soil conditions. Among the ten conclusions drawn from the comprehensive tests reported in this paper are that the most important factor affecting the coefficient of traction or tire thrust of rubber-tired tractors is the nature or surface of the operating soil; that, for a given soil, the most important factor is the weight that the tire carries; and that inflation pressure has a relatively small effect.

Improvement in Stopping Ability Of Trucks in Use on the Highway

RESULTS of tests conducted on more than 5400 vehicles show that since 1942 there has been considerable improvement in the brake performance of all types of motor vehicles using our highways. A gap existing between the levels of performance of commercial vehicles and passenger cars has been reduced. However, through adequate brake maintenance, the performance of commercial vehicles still can be improved appreciably, and the gap between the performance of trucks and passenger cars can be narrowed still further. This paper shows the magnitude of past improvement, the current levels of brake performance, and how the brake performance of commercial vehicles can be further improved through maintenance.
