Son 1, first switch Q1 conductings, now the first relay K1 conductings, terminal 17 is separated with terminal 18, open fault signal note
Enter, when open fault injection reaches that the open fault injects duration, the output low level signal of control unit 120 to terminal 1, now
First switch Q1 and the first relay K1 is disconnected, and is turned between terminal 17 and terminal 18, and open fault is released；Control unit 120
According to be shorted to power failure signal input time output high level signal arrive terminal 5, second switch Q2 turn on, now second after
Electrical equipment K2 is turned on, short circuit between terminal 9 and terminal 10, is shorted to power failure signal injection, is shorted to power failure injection and is reached
When power failure injection duration is shorted to this, control unit 120 exports low level signal to terminal 5, now second switch Q2
Disconnected with the second relay K2, terminal 9 is separated with terminal 10, be shorted to power failure releasing；Entire car controller output is high
Side drive signal, so as to be high level between entire car controller and electronic load, control unit 120 is believed according to earth fault is shorted to
Number input time output high level signal arrives terminal 11, the 3rd switch Q3 conductings, and now the 3rd relay K3 is turned on, terminal 15 and
Short circuit between terminal 16, the level between entire car controller and electronic load is dragged down, and completion is shorted to the injection of earth fault signal,
When being shorted to earth fault injection and reaching that this is shorted to earth fault injection duration, control unit 120 exports low level signal to terminal
11, now the 3rd switch Q3 and the 3rd relay K3 disconnections, terminal 15 is separated with terminal 16, is shorted to earth fault releasing,
Entire car controller turns off flash drive signal, and test is completed, and entire car controller generation failure detection result is simultaneously defeated by CAN communication
Go out to control unit 120, the failure detection result is output to monitoring equipment by control unit 120 by network communication.
The flow chart of above-mentioned flow is as shown in Figure 8.
For the direct fault location flow and the effective entire car controller of above-mentioned high level of the effective entire car controller of low level
Similar, difference is, before carrying out being shorted to the direct fault location of power supply, and entire car controller will export low side driving letter
Number, so as to be low level between entire car controller and electronic load.Afterwards, control unit exports high level to terminal 5 again, this
Sample, after the second relay K2 conductings, can draw high the level between entire car controller and electronic load, thus complete to be shorted to
Power failure signal injects.When being shorted to power failure releasing, entire car controller turns off low side drive signal.In addition, entering
Row is shorted to before the direct fault location on ground, and entire car controller need not export flash drive signal, because being led in the 3rd relay K3
It is low level between entire car controller and electronic load, now, the effective entire car controller of low level is able to detect that this when logical
One fault-signal.
