Instruction state, the step include: to enter the self-test stage after onboard system is switched on, and first processor or second processor are respectively to right
Side sends detection messages, receives the reply data packet of return at setting time interval in first processor or second processor,
And the reply data packet returned is successful respond, it is determined that first processor or second processor are all in normal operating conditions；
If first processor or second processor are not received by the reply data packet of return at setting time interval, or what is returned answer
Answering data packet is unsuccessfully to reply, it is determined that first processor or second processor exist abnormal, wherein if first processor or
There is exception in second processor, then restart in the presence of abnormal processor.
Specifically, first processor and second processor can mutual self-test, to guarantee normal operation of terminal, and export and open
Measure instruction state in pass.When onboard system enters the self-test stage in booting, second processor sends message to first processor, and first
Processor returns to successful respond, shows that first processor is in normal operating conditions, first processor can be by packaged number
It is sent to second processor according to packet, when first processor sends data packets to second processor at set time intervals
Afterwards, first processor can receive the successful respond of second processor, show that second processing is in normal operating conditions.
In an alternative embodiment, if there are still exceptions for the processor after restarting, abnormal processor will be present
It is determined as failure processor；Wherein, if first processor is failure processor, it is flat to long-range monitoring to trigger second processor
Platform sends failure message, if second processor is failure processor, controls first processor for collected driving recording
Data backup is to scheduled memory space.
Pass through the mutual self-test and abnormality processing of first processor in onboard system and second processor, it is ensured that vehicle-mounted
The normal operation of system terminal.
In an alternative embodiment, in the case where onboard system enters dormant state, first processor and second
Processor enters low-power consumption working condition, and retains switching value interruption.According to the requirement of power consumption and wake-up mode, can flexibly set
Set the interruption of first processor and second processor.
Specifically, when vehicle is in low-power consumption situation, onboard system enters dormant state, at this time close CAN transceiver,
Positioning unit, communication module and first processor, second processor are in low-power consumption work, only retain in On-off signal
It is disconnected.
Optionally, under the low-power consumption working condition first processor and second processor receive wake-up signal it
Afterwards, it is interrupted by switching value and wakes up second processor, and controlled second processor and wake up first processor.
Specifically, in charging or fired state, first processor and second processor receive wake-up letter
Number, onboard system is interrupted by switching value and wakes up second processor, and is controlled second processor and waken up first processor.
