PURPOSE:To easily decide whether or not the non-lock state (OFF state) of a center differential is normal or not by detecting and comparing the differences in rotating speed of front-side output shafts and a rear-side output shaft. CONSTITUTION:The driving transmission system for a vehicle is provided with the front-side output shafts 9 and 10 which outputs the driving power from an input shaft 2 through a front differential 8 and the rear-side output shaft which outputs the driving power from the input shaft 2 through the center differential 12 which has a lock mechanism 11. Then the front-side output shafts 9 and 10 are loaded to detect the differences in the rotating speed between the front-side output shafts 9 and 10 from the rotating speed of the input shaft 2, and the detected values are compared with a set value to decide the operation confirmation of the lock state of the center differential 12. Further, the rear-side output shaft 13 is loaded to detect the differences in the rotating speed of the rear-side output shaft 13 from the rotating speeds of the front-side output shafts 9 and 10, and the detected values are compared with the set value to decide the operation confirmation of the non-lock state of the center differential 12. |
