Volume, weight.The present invention significantly reduces the manufacturing cost of electric machine controller, in the electric machine controller for using at present, into
Instinct reduces by 480 yuan
Preferably, step 3：After conducting on electric machine controller, postpone 3-5 seconds BMS and perform self-inspection step again, if
BMS self-detection results then stop performing de-energizing actions to electric machine controller for mistake, if BMS self-detection results are qualified, continue dimension
Hold standing state.It is of the invention so to arrange, the mode of continuous self test twice is employed, not only ensures there is safe shape before upper electricity
State, while also can be processed immediately once going wrong in power up.
Preferably, step 3：After conducting on electric machine controller, postpone 5-8 second electric machine controllers and perform self-inspection again
Step, stops the adhesive action to car load high pressure line box main relay if electric machine controller self-detection result is mistake；If motor
Controller self-detection result is qualified, then continue to standing state.It is of the invention so to arrange, employ the side of continuous self test twice
Formula, not only ensures there is safe condition before upper electricity, while also can be processed immediately once going wrong in power up.
Preferably, message twice is sent to BMS after electric machine controller self-inspection is completed in electric machine controller self-inspection step,
The cipher mode of the message twice is identical.Although twice message be sent to can little delay, prevent error message, one
Message is different twice for denier, judges that current self-inspection is unqualified immediately, and security is higher.
Preferably, the On-board LAN is vehicle-mounted CAN bus network, electric machine controller self-inspection completes backward BMS and sends out
The message for sending is limit priority message.
Preferably, the electric machine controller selftest module is low pressure self-checking circuit.
The present invention substantial effect be：The relay of motor controller controls is cancelled by this patent, is patrolled by CAN controls
Volume, increasing controls of the BMS to main relay, BMS is controlled to main relay by CAN communication, it will be apparent that reduce motor
The manufacturing cost of controller, reduces volume, the weight of electric machine controller.The present invention significantly reduces the system of electric machine controller
This is caused, and in the electric machine controller for using at present, 480 yuan is reduced into instinct
