In one embodiment of the invention, before the ignition lock state switching vehicle, need to carry out initialization and self-inspection to relay array.When system is suddenly stopped or exits time, ignition lock is automatically switched to OFF state.
As shown in Figure 7, first perform step S701, carry out system initialization, comprise the connection of relay-operated controller and state self-inspection and initialization, upper computer software self-inspection.If self-inspection success, then perform step S703, otherwise perform step S702.
Step S702, sends the prompting of System self-test failure.
Step S703, arranges the holding time of igniting switching over state and state.
In time input field after often kind of ignition lock state, can this state retention time be set according to demand.Wherein, the time precision of state retention time depends on the timing parameters of upper computer.Such as, the holding time of OFF state can be 1 second, and the holding time of ON state can be 3 seconds, and the holding time of START state can be 3 seconds.
Step S704, performs an action.
To connect between the ignition lock wire harness of vehicle according to the ignition lock switching state arranged and disconnect, thus realizing ignition lock switching state vehicle being switched to setting.If do not receive washout or exit signal, then terminate this and switch.
Step S705, emergent stopping.
System sends washout or exits signal.It should be noted that, this step is optional step, only performs when system generation problem.
Step S706, is switched to OFF state by ignition lock.
