<p>PROBLEM TO BE SOLVED: To provide a steering-angle shift amount measurement method and a measurement system, which enable high-precision and efficient measurement of a steering-angle shift amount, with a load on a worker reduced.SOLUTION: A steering-angle shift amount measurement method for a vehicle travelling on a road includes: obtaining a change in a steering angle of a vehicle with a steering level instrument incorporated in the vehicle, a change in a speed of the vehicle with an acceleration sensor incorporated in the vehicle and, a change in a travel direction of the vehicle with a gyro sensor incorporated in the vehicle (step S2); selecting, as a selected section, a section where the three changes are respectively within set thresholds (step S4): determining whether the change in the steering angle immediately before the selected section is within a threshold and determining whether the change in the speed immediately after the selected section is within a threshold (step S5); and setting the selected section as a steering-angle shift amount measurement section if the result of the two determinations are within a threshold (step S6).</p> |
