It is built-in when being vehicle release to lock detection function；If so, BCM wakes up the entire car controller (1)；The entire car controller
(1) the low-voltage power supply relay for controlling power domain controller is attracted；
The low pressure of entire car controller (1) the control power domain controller wakes up supply relay and is attracted, and enters step S203；Institute
Stating power domain is a set, and all controllers and components belong to power domain, including power battery management in addition to BCM
Device, high-tension distribution box, drive motor controller, fuel cell system, fuel cell controller, power battery and driving motor；
S203: judge whether to request high pressure if so, connecting && vehicle CAN communication Zheng Chang && in vehicle high-voltage interlocking signal
In the case that vehicle is without three level Four failures, the entire car controller (1) controls power battery manager (4) high pressure and powers on,
Enter step S204；Otherwise, then vehicle keeps low-pressure state, and flag bit HBMS_Flag remains 0, jumps to step S213；Institute
Stating high-voltage interlocking signal is the entire car controller (1) common marking signal, for judge vehicle circuit whether connect it is complete,
Monitor high tension loop etc.；The three level Four failure, comprising: hydrogen surplus is low, Hydrogen Vapor Pressure is insufficient and hydrogen leak；
Does is S204: judgement symbol position HBMS_Flag 1 if so, the entire car controller (1) controls the high voltage power distribution
High pressure on case (7), enters step S205；Otherwise, step S212 is jumped to；
Does is S205: judgement symbol position HPDU_Flag 1 if so, the entire car controller (1) sets the driving motor
Controller (9) is torque control mode, concurrently sets it as operational mode, can respond the torsion of the entire car controller (1) at any time
Square request；The entire car controller (1) sets the reducing transformer (8) and enables, and enters step S206；Otherwise, step is jumped to
Rapid S210；
S206: judge whether that the drive motor controller (9) working condition is in working condition for reducing transformer (8) described in operation &&
Does is it standby normally to export the fuel cell system (3) working condition if so, the flag bit Ready=1, indicates
Vehicle reaches travelable state；Otherwise the flag bit Ready=0 carries out electricity under high pressure, jumps to step S207；
S207: the Working mode set that the entire car controller (1) controls the drive motor controller (9) is that high pressure is standby；
S208: the entire car controller (1) controls the fuel cell controller (2), and then controls the fuel cell system
(3) permit electricity under high pressure；
S209: it is non-enabled that the entire car controller (1) controls the reducing transformer (8)；
S210: do you judge that the high-tension distribution box (7) bus current is less than safe current value if so, the full-vehicle control
Device (1) controls electricity under high-tension distribution box (7) high pressure, enters step S211；Otherwise, step S210 is continued to execute, until female
Until line current is less than safe current value；The safe current value is different and different according to different manufacturers contactor equipment itself,
It is determined with specific reference to used Hardware Description Manual；
S211: the drive motor controller (9) actively releases energy to the high-tension distribution box (7)；
S212: the entire car controller (1) controls the power battery manager (4) and carries out electricity under high pressure；
S213: vehicle returns to low-pressure state, and keeps；
S214: request electric under low pressure if so, the low-voltage power supply relay in entire car controller (1) control power domain,
Low pressure wakes up supply relay and disconnects；The entire car controller (1) enters suspend mode, and go to step S201, and vehicle is again
In dead ship condition；Otherwise, step S213 is returned to.
