In the present embodiment, power assembly part had both sent message by CAN to hybrid controller HCU, together
When send message to HCU redundance unit association controller again, it is assumed that what the former sent is the second message, and what the latter sent is first
Message, then object is different, and its content is identical except message receives for the first message and the second message.First message and
Second message can be the clearly specified message for receiving object；It can also be the indefinite specified broadcast report for receiving object
Text, such as the status information message of reflection power assembly unit status, the present invention are not specifically limited.
When HCU does not break down, it is responsible for controlling power assembly part to be operated according to the second message by HCU,
In order to not produce control hazard, association's controller only receives the first message, power assembly part is not controlled.Moreover, work as HCU
Output pin (flash drive pin and low side driving pin) be not damaged, HCU to power assembly part send enabling signal,
The enabling signal includes power on signal and enable signal.HCU to power assembly part after power on signal is sent, periodically
Enable signal is sent to the power assembly part, so that the power assembly part is in running order, it is in running order
Power assembly part by CAN to HCU send message so that HCU according to message control power assembly part.If HCU
Judge not needing power assembly component working, or the message being sent to according to power assembly part to judge power assembly
Unit failure needs to be stopped immediately, then HCU sends the message being stopped by CAN to power assembly part, moves
Power assembly part is stopped immediately after the message being stopped is received.Meanwhile HCU no longer by rigid line to the power
Assembly part sends enabling signal.
Step S102：If association's controller judges that the power assembly part does not occur according to first message
Failure, association's controller are not received by from the power in the preset time period after receiving first message
Any message of assembly part, and it is total to the power to be not detected by the preset time period hybrid controller

Flash drives pin or the low side driving pin to be attached.In the case where HCU pin does not have failure, controller is assisted
Pin is in high-impedance state, does not send enabling signal to power assembly part.
When the first message that association's controller is sent to according to power assembly part judges that the power assembly part does not have
Break down, and do not received again from the power assembly in preset time period after the first message is received
In the case of any message of part, if detecting the HCU to the power assembly part in the preset time period
The message being stopped is sent, then illustrating the power assembly part is normally stopped according to HCU instruction；But if
Do not detect that the HCU sends the message being stopped to the power assembly part in the preset time period, then
Illustrate that the power assembly unit exception is stopped, that is to say, that property that there is a strong possibility is due to and the power assembly portion
The HCU of part connection flash driving pin or low side driving pin damage, cause HCU can not continue to send out to the power assembly part
Enable signal is sent, and causes power assembly part to be stopped suddenly.Because such case is abnormally dangerous when driving, because
Once there is the situation in this, and coprocessor just replaces HCU to send enabling signal to the power assembly part, so that the power
Assembly part works on.In order to further ensure that the safety of vehicle and rider, when the power assembly part is resumed work, and
Continue to send message to HCU and association's controller, if association's controller receives the 3rd report that power assembly part is sent to
Text, then take over the HCU and control the power assembly part to be operated.In addition, association's controller can also control vehicle
Display device show fault message, to remind user to repair as early as possible, or by CAN to the HCU report HCU failures
Information, and it is HCU pin fails to illustrate in messages, and HCU can take after being connected to the message of the HCU failures
Ensure the measure of vehicle safety operation.Such as if vehicle HCU pins during running at high speed break down, then HCU can be with
The associated components prompting driver failure situation is controlled immediately, so that driver takes the measures such as reduction of speed, stopping traveling, and/or,
HCU can also take the stringent effort such as some limitation moment of torsion, restricted speeds automatically, prevent driver from having little time to react and cause thing
Therefore.
