9. belt tension method according to claim 8, which is characterized in that step S30 further includes defeated to controller (500)
The current value gone out is judged that, when the current value that controller (500) exports is greater than the set value, controller (500) sends out alarm
Signal reminds driver and passenger to overhaul belt drive system.
10. a kind of automobile, which is characterized in that including belt drive system as claimed in any one of claims 1 to 6.
