Working process is as follows:

1, when the right steering lamp is opened, under the state that driver's side door shuts: because reset switch J1 is in on-state, when driver's side door shuts, there is power supply to insert from the DOOR+ end, make the first aerotron Q3 conducting, low level of the 12nd pin input of the first integrated circuit U2-D, simultaneously, when the right steering lamp is opened, insert power supply from RIGHTLAMP, high level of the 13rd pin input of the first integrated circuit U2-D, high level of the 11st pin output of the first integrated circuit U2-D, low level of the 10th pin output of the second integrated circuit U2-C, this low level is controlled the first not conducting of silicon control Q4; At this moment, the Q12 pin output low level of microprocessor U1 is controlled the second not conducting of silicon control Q2, thereby relay K 1 dead electricity, contact switch Ka, Kb are in normal on-state, do not influence the running state of external Engine ECU electric power loop, low tension ignition circuit control loop, oil pump loop or FP Fuel Pump Relay control loop.Whole antihijacking device is in readiness for action, at this moment, and relay indicating light Chang Liang.

2, if the right steering lamp is opened the back and driver's side door was opened: at this moment, side door switch DOOR+ ground connection, the first not conducting of aerotron Q3, high level of the 13rd pin input of the first integrated circuit U2-D, high level of the 12nd pin input of the first integrated circuit U2-D, low level of the 11st pin output of the first integrated circuit U2-D, the control first silicon control Q4 conducting behind high level of the 10th pin output of the second integrated circuit U2-C; The anode voltage control of the first silicon control Q4 triggers the RESET end of the 3rd integrated circuit U1, and the Q4 pin outputting oscillation signal of microprocessor U1, LED lamp receive oscillator signal and begin flicker, and the flame-out function of expression time-delay starts; Behind predefined delay time (as: 3 minutes), the Q12 pin output high level of the 3rd integrated circuit U1 is controlled the second silicon control Q2 conducting, thereby relay K 1 gets electric adhesive, contact switch Ka, Kb disconnect, thereby disconnect the power supply that is connected Engine ECU electric power loop, low tension ignition circuit control loop, oil pump loop or FP Fuel Pump Relay control loop with it, automobile cuts off the power supply automatically, oil-break stops working and can't restart.

As required, can change delay time by the resistance of adjusting resistance R 3.

3, press pressure hand switch J2, the second silicon control Q2 conducting, relay K 1 gets electric adhesive, thereby disconnects the power supply of external Engine ECU power supply, low tension ignition control circuit, oil pump or FP Fuel Pump Relay control circuit, and the automobile automatic fuel cut-off during stops working and can't restart.

4, close as if the right steering lamp, disconnect reset switch J1, the first not conducting of aerotron Q3, low level of the 13rd pin input of the first integrated circuit U2-D, low level of the 12nd pin input of the first integrated circuit U2-D, high level of the 11st pin output of the first integrated circuit U2-D, the control first not conducting of silicon control Q4 after low level of the 10th pin output of the second integrated circuit U2-C; The Q12 pin output low level of the 3rd integrated circuit U1 is controlled the second not conducting of silicon control Q2, thereby relay K 1 dead electricity, contact switch Ka, Kb are in normal on-state, do not influence the state of external Engine ECU electric power loop, low tension ignition circuit control loop, oil pump loop or FP Fuel Pump Relay control loop.At this moment, relay indicating light extinguishes.

Insert the working process and above-mentioned access right steering lamp power supply identical (being omitted) of lampet power supply (WIN LAMP).

Generally speaking, because the around the clock service of right steering lamp, and lampet is only worked at night, therefore, the utility model only needs to rely on right steering lamp and the anti-misfortune of driver's side door Collaborative Control when well lighted, and when night or light are dark, rely on that right steering lamp, lampet and driver's side door Collaborative Control are anti-robs.

The utility model, particularly the utility model device should be installed in shelter, trunk or front goods case below as far as possible.In addition, flame-out for fear of mistake, should before normally getting off, lampet and right steering lamp be closed.
