Description / Abstract:
This test procedure is used to determine the steady-state
directional control response of vehicles by measuring steady-state
cornering behavior. Due to the wide range of operational conditions
to which a vehicle can be subjected, the results of this testing do
not provide a complete description of a vehicle's total dynamic
behavior; in particular, the procedure does not test the vehicle's
response during transient maneuvers. To fully assess a vehicle's
total dynamic behavior, it would be necessary to conduct other test
procedures in order to evaluate the vehicle's performance as a
whole.
The extent of instrumentation and the required accuracy of the
measurement will be dependent on the goals of the personnel
conducting the test. If it is desired simply to determine the
general performance characteristics of a vehicle, then this test
can be conducted with minimal instrumentation and test item
preparation.
Purpose—This SAE Recommended Practice
establishes a uniform procedure for determining the steady-state
directional control response of trucks, buses, and combination
vehicles.
