MEASUREMENT DATA ACQUISITION SYSTEM, SADDLED VEHICLE HAVING MEASUREMENT DATA ACQUISITION SYSTEM, METHOD, AND COMPUTER PROGRAM

The measurement data acquisition system (180) includes: a wheel rotation speed sensor (11 b) configured to acquire a first wheel rotation speed, wherein the first wheel rotation speed is a rotation speed of the first wheel (3); a vehicle speed sensor (11a) configured to acquire a vehicle speed of a test vehicle (100); an attitude detection unit (11c) configured to acquire a bank angle of a vehicle body (1) of the test vehicle (100); and an arithmetic unit (30) configured to, during travel at a predetermined bank angle and in the absence of any braking force or driving force, acquire measurement data (55) representing a relationship between the first wheel rotation speed and the vehicle speed. The measurement data (55) is to be installed in a predetermined vehicle for use in determining a relationship between the rotation speed of a wheel of the predetermined vehicle and the vehicle speed of the predetermined vehicle during travel of the predetermined vehicle at the predetermined bank angle.
