It is essential to attain accurate understanding of vehicle service loads for customer usage and to reflect this understanding into development test conditions established to ensure strength and durability. The Road Load Standardization Subcommittee* of the Japan Society of Automotive Engineers (JSAE) Fatigue and Reliability Committee has therefore employed direct measurement and new analytic methods in an attempt to quantify Japan-wide on road service load data. This quantified data has been used as the basis to standardize road loads for a wide range of vehicle categories. The following were major considerations in the implementation of this research:
Employment of a 6 degree of freedom (6DOF) wheel force transducer (increased measurement accuracy)
Identification of load from road input vs input from driving operation generated. (Increased test mode accuracy)
Measurements conducted on 350 separate routes across Japan (Increased analytic accuracy)
Standardization by employing vehicles from a wide range of categories on the same routes (Generation of multi-purpose data)
