For the number of repetition for each road used in the vehicle durability test on the proving ground, apply the drive signal for each road pattern to the actuator. It is desirable to apply signals according to the driving sequence in

During test, check each portion for presence of cracks, excessive play, permanent deformation and loosening of bolts and nuts through visual inspection and with
