Structure is that motor axle exports a predetermined rotating speed；
Locking control unit, for sending locking order to electronic gear shifter by CAN, control electronic gear shifter is to motor
Carry out locking operation；
Lockup state detection unit, after the scheduled time that the locking command sending unit sends locking order, by detection
Whether the velocity amplitude of the speed probe of differential mechanism is current in lockup state to judge；
Validation checking unit, for after locking validation checking unit detects successfully locking, by CAN to electronics
Whether selector sends the numerical value that the position sensor of halting mechanism is read in order, detect the numerical value in predetermined effective locking
In the range of, if testing result is the numerical value not in the range of predetermined effective locking, it is determined that locking not yet in effect；Otherwise, really
Fixed effective locking.
A kind of 11. systems detected to parking locking mechanism rigging position as claimed in claim 8, it is characterised in that
The unlocked position validation checking unit is specifically included：
Rotary speed controling unit, control command is sent by CAN to rotating speed input mechanism, controls the rotating speed input mechanism to be
Motor axle exports a predetermined rotating speed；
Lockup state detection unit, the velocity amplitude for the speed probe by detecting differential mechanism is determined whether in lock
Only state；
Unblock control unit, for when state detection unit is detected and is currently at lockup state, being sent by CAN and being solved
Lock control order, control electronic gear shifter is unlocked operation to motor；
Unblock detection unit, for after the unblock control unit sends the scheduled time of unblock control command, by detection
Whether the velocity amplitude of the speed probe of differential mechanism reaches normal rotating speed output, to detect whether successfully to unlock；
Validation checking unit, for when the unblock detection unit is detected and successfully unlocked, being sent by CAN and being ordered
The numerical value of the position sensor of electronic gear shifter halting mechanism is read in order, and whether the numerical value is in predetermined effective unblock scope
It is interior, if testing result is the numerical value in the range of predetermined effective unblock, it is determined that effectively unlock；Otherwise, it determines not having
Effect unblock.
