As shown in Figure 4: it has 8 relays, is respectively: J1, J2, J3, J4, J5, J6, J7, J8. are above-mentioned can all be described in detail to line and the public affairs of J1, J2, J5, J6., just repeats no more here.

J3 is air conditioner electric magnetic clutch control relay, and function is control engine when starting, and air-conditioning is in disengaged position, reducing starting load. mode of operation is that, after driving engine is started working, J3 obtains electric, connect the air condition clutch line, at this moment air-conditioning just enters the strong state of accurate work; J4 has two functions; The one, the signal that provides driving engine whether to work for micro controller system, there are No. 55 lines of 4 pin connections of J4 to complete. the 2nd, control starter work, after engine starting comes, J4 obtains electric, cut off starter power by 13 and 11 pin. simultaneously, 4,8 pin are connected the output engine working signal; The function of J7 and the functional similarity of J3, it is used for controlling headlight; J8 is the cooling fan F1 that controls high-power partition diode D4, D5, D6, D7 temperature, J8 has temperature switch T1 to control, be raised to 65 while spending when cutting off diode temperature, thermal switch T1 will open, 4,6 pin of J8 will the closed power supply of connecting fan F1, makes its work, after temperature is fallen, 4,6 pin of J8 will disconnect, F1 dead electricity and stopping.

The gear detector switch is arranged on lever, and the direction ratio moved due to gear work is larger, and the position that neutral gear place lever is parked is not again very accurate, and this has brought very large difficulty to the selection of element.Through the selection of tens of middle elements and loading stress repeatedly, finally chosen the dry-reed tube magnet-switch.

What clutch switch adopted is common limit switch.

The diode that generator power supply place on driving engine arranges is connected on the charging line of electrical generator and storage battery, it is heavy-duty diode, when engine operation, just drive electrical generator work output electricity, the diode input end is obtained electric, detect having or not of this electricity and just can judge whether driving engine works.Charging current herein is larger, surveys the left and right into 7A, cuts off the diode heating than very fast, therefore will resolve the heat dissipation problem that cuts off diode.Also will complete the another one function in this detection, both: the vehicle starter starting must, in the situation that minimum load starts, be guaranteed the success ratio of starting simultaneously.At this moment just need draw power supply at this check point, install relay additional on-board air conditioner, headlight is controlled.While making engine starting, air-conditioning and headlight all break away from mode of operation, thereby reach the reliability of the each starting of driving engine.

Because micro controller system working environment onboard is very bad, the electromagnetic interference on car is very serious.The high tension ignition of driving engine, high-power electric appliance use etc. on car, be subject to the restriction of installing space, interference source from micro controller system very close to, therefore need to carry out the isolation of electromagnetism photoelectricity and isolated from power to circuit card and element, input/output signal has all strictly been carried out to electromagnetic isolation, and on software, adopted clock to interrupt the monitoring and reset program, its various functions is reached the fully requirement of anticipation.
