It such as finds that the first controlling bus breaks down, enters step three；It such as finds that the second controlling bus breaks down, enters step four；
It such as finds that two controlling bus break down, enters step five；
Step 2: the first control module and the second control module respectively by respective controlling bus and entire car controller into
Row communication；
Step 3: stopping the use of the first controlling bus, the control signal transmission function on spi bus is activated, by the
Two controlling bus and spi bus maintain the communication between the first control module and entire car controller, meanwhile, it generates on fault-signal
It reports to entire car controller；
Step 4: stopping the use of the second controlling bus, the control signal transmission function on spi bus is activated, by the
One controlling bus and spi bus maintain the communication between the second control module and entire car controller, meanwhile, it generates on fault-signal
It reports to entire car controller；
Step 5: the control signal transmission function on activation spi bus, switching uses the first controlling bus and the second control
Bus carries out the communication between entire car controller and two control modules, until realizing communication or receiving stopping for entire car controller
Only order.
For above-mentioned framework, since controlling bus there are two, it is equivalent to and gives three calibration diagnosis channels, therefore can be with
Diagnosis communication method is demarcated using following bi-motor, is included the following steps：
Step 1: the communication condition of the calibration ALCL Assembly Line Communication Link between detection control module and calibration diagnostic device, does not send out such as
Existing failure, enters step two；It such as finds that calibration ALCL Assembly Line Communication Link breaks down, enters step three；
Step 2: control module is communicated by demarcating ALCL Assembly Line Communication Link and calibration diagnostic device；
Step 3: stopping the use of calibration ALCL Assembly Line Communication Link, the calibration diagnostic signal in the first controlling bus is activated to transmit work(
Can, the transmission of calibration diagnostic signal is carried out by the first controlling bus；If the first controlling bus breaks down, then the second control is activated
Calibration diagnostic signal transfer function in bus processed, and by the first controlling bus carry out calibration diagnostic signal transmission.
Fault-signal is generated, and by controlling bus while stopping calibration ALCL Assembly Line Communication Link use for step 3
Pass the fault-signal.
Under normal conditions, the signal receiving device of the controlling bus other end can be entire car controller, can also be direct
The calibration diagnostic device of connection on the control bus.
