Abstract:

This TOP provides standardized tests for evaluating wheeled vehicle braking systems. Because it is associated with personnel safety, thorough testing and evaluation of a vehicles braking capability is required to assure dependability and effectiveness under a variety of conditions. Major factors to be considered in the evaluation of vehicle braking systems are stopping and grade holding ability, vehicle stability and control during brake applications, and individual braking component endurance under various operational conditions. The use of advanced technologies in brake system design will dictate the test design necessary to ensure the system is safe and effective. Some of these technologies include the use of auxiliary brake systems in heavy trucks, regenerative braking in hybrid vehicles, antilock braking systems, and electronic stability control brake systems. Requirements and procedures for brake system testing are contained in documents such as the Federal Motor Vehicle Safety Standards and the Society of Automotive Engineers procedures. This TOP identifies procedures and requirements for vehicles designed for military operations.
