In CAN1 buses, an address is only assigned with for control module, under same address, for different controls The information of module is made a distinction by packet；Information for specifying the second control module, the first control module are total by SPI Line passes to the second control module.

In CAN0 buses, then normal condition and abnormal condition are divided into.

Under normal condition, in CAN0 buses, one is each assigned with for the first control module and the second control module Address, i.e., information from CAN0 buses can according to corresponding to directly reaching address control module without from some control mould Block is transferred, and now only diagnostic signal is demarcated in interaction on spi bus.

Under abnormal condition, the communication between some control module and vehicle communication interface there occurs failure, such as CAN01 failures, after this failure is detected, CAN01 is stopped, and the control signal for being sent to the first control module passes through CAN02 sends to the second control module, and made a distinction by packet, and the second control module passes information by spi bus Pass the first control module；The information come for the first control module transmission, the second control module is received laggard by spi bus Row processing, and under the address of oneself, vehicle communication interface is passed to by CAN02 buses, and eventually through CAN0 send to Demarcate diagnostic device.Now interactive controlling signal is gone back on spi bus in addition to demarcating diagnostic signal.

For above-mentioned framework, because controlling bus there are two, therefore the following Double Motor Control means of communication can be used：

For above-mentioned framework, because controlling bus has two, equivalent to giving three demarcation diagnosis passages, therefore can be with Diagnosis communication method is demarcated using following bi-motor, comprised the following steps：

For step 3, while demarcation ALCL Assembly Line Communication Link use is stopped, fault-signal is produced, and by controlling bus Pass the fault-signal.
