The mark formed when record steering wheel is respectively at limit on the left position and limit on the right-right-hand limit position with the relative positional relationship of the second object of reference
Know region shape；
S07: judging whether the identified areas shape of two extreme positions in left and right and the second object of reference is consistent or symmetrical, if it is determined that
For "Yes", it is considered as steering wheel and is in Shaft alignment state, centering process is completed；Otherwise return step S06, and to the installation position of steering wheel
It sets and is adjusted.
Preferably, second object of reference is to turn to lock housing；In step S07, when steering wheel turns to limit on the left position,
First identifier region is formed by steering wheel and the relative positional relationship for turning to lock housing；Then steering wheel is turned into limit on the right-right-hand limit position
It sets, second identifier region is formed by steering wheel and the relative positional relationship for turning to lock housing；Judge first identifier region and second
Whether the shape of identified areas is consistent or symmetrical, if it is determined that "Yes", is considered as steering wheel and is in Shaft alignment state, centering process is complete
At；Otherwise return step S06, and the installation site of steering wheel is adjusted.
Preferably, the specific method of step S02 is: when steering wheel is in left or right extreme position, marking on the steering wheel
First object of reference；Steering wheel rotation to the other side the right side or limit on the left position, using the first object of reference as initial position artificial counting
Turnning circle；
Preferably, first object of reference is the spoke of steering wheel.
The beneficial effects of the present invention are:
Due to can determine whether steering wheel turnning circle by steering wheel rotation.Simultaneously by steering wheel from extreme position revolution two/
One turnning circle, can determine that out the stroke middle position of diverter in steering system, and make steering shaft that diverter be driven to go to
The diverter travel position of half.
This method is without complicated software and instrument controlling, in no steering wheel centering equipment, tooling or device parameter
Before not updating, manually centering is carried out to steering wheel rotation.This method is simple, and efficiency is higher, and reliability is preferable, can keep away
The occurrence of exempting from because of no equipment, tooling to which steering wheel centering can not be carried out.
