As a kind of implementation, the received instruction for starting learning remote control key of anti-theft control unit, is by antitheft
Practise what communication apparatus was sent.Antitheft study communication apparatus is the OBD(On-Board Diagnostic for being connected to vehicle, vehicle at this time
Carry auto-check system) interface.
After anti-theft control unit receives the instruction for starting learning remote control key, that is, started for the first time-count cycle.In this hair
In bright, the purpose of the first time-count cycle of setting is, should can be just to one time limit of process settings of learning remote control key
In completing study (cannot be arranged too short), meet the requirement of producing line beat (cannot be arranged too long), therefore, the embodiment of the present invention again
The first time-count cycle be set as -15 seconds 5 seconds.
A purpose for being arranged for the second time-count cycle is similar the first time-count cycle to setting, completes study also for taking into account
With the requirement of producing line beat.It is pressed in the correct order since whether anti-theft control unit will judge to receive within a certain period of time
Each correct push button signalling of function button, is used as the certain time if by the first time-count cycle on remote-control key to be learned,
So the duration of the first time-count cycle can seem too long relative to the duration for pressing each function button, lead to unnecessarily time wave
Take.In addition, the first time-count cycle and the second time-count cycle and depositing also to the embodiment of the invention provides a kind of heavy by mechanism, avoid
Single time conditions are unsatisfactory for i.e. feeding back unsuccessful and interrupt the not high defect of learning efficiency brought by learning process, improve this hair
The practicability of bright learning method.Although for example, do not received within second time-count cycle press in the correct order wait learn
Each correct push button signalling of function button on remote-control key is practised, but as long as still within the first time-count cycle, operator can be with
