The user for initiating this vehicle unlocking request does not have unlocking qualification, at this point, this vehicle unlocking request is recorded as asking
Failure is asked, and the request frequency of failure of the vehicle unlocking request is added one.It should be noted that the vehicle solution recorded each time
The number of the request failure of lock request will add up, but when controlling end in vehicle has through the vehicle unlocking request, namely
When carrying out unlock to vehicle, the number of the request failure of the vehicle unlocking request recorded before this will be reset.For example,
If there is continuously vehicle unlocking request cannot pass through three times, then records at this time and the request of cumulative vehicle unlocking request failure is secondary
Number is 3, at this point, if vehicle unlocking request next time is passed through by control end in vehicle, the vehicle unlocking request recorded before this
The request frequency of failure be 3 result reset, i.e., the request frequency of failure of vehicle unlocking request is 0, and start recording again.
S70, when the request frequency of failure of the vehicle unlocking request be greater than preset lock threshold when, to the vehicle into
Row locking.
In one embodiment, the request frequency of failure of the vehicle unlocking request further includes being remembered in the step S401
