As it was previously stated, above-mentioned 6 kinds of situation conditions may be alternately present in a checking procedure, and when being alternately present, one
Denier reaches certification success（Successful release）Or key is mismatched（PEPS failure）Condition, directly by VCU_
Released set is ' VCU released' or ' VCU locked'；And when constantly replacing under the conditions of other four kinds, need
Constantly repeat to initiate verification, because the repetition initiation upper limit number of times of these four situations is not identical, therefore have identical weight
The situation for having recurred upper limit number of times is multiplexed an identical repetition initiation counting, and any one repetition is initiated counting and reached thereon
All should be by VCU_Released set during limit number of times ' VCU locked'.
It should be noted that, before step S1, user operation activate switch, PEPS set IGN ON relays are in
IGN ON states, VCU detection KeyOn pin voltages, voltage reaches certain value, then starts identifying procedure.If certification does not pass through
Or key certification time-out, in IGN ON states, user operation activate switch, during PEPS set Start Relay, VCU detects Key
Start pin voltages, voltage reaches certain value, and VCU should again initiate the identifying procedure with PEPS.
Thus, the present embodiment also included before step S1：
When the PEPS power supply status are in IGN, if the VCU has been received by key power on signal, execution step S1.
If key certification is overtime, when the PEPS power supply status are in START, the VCU is opened receiving key
Execution step S1 during dynamic signal.
