● gear number (such as 7 grades of DCT, have 1-7 gear, because that should have 7 strategies herein) shelves of shielding design.
Above-mentioned alternative strategy can be designed to the variable of a uint32 in software.If the variable is talked about with binary representation
Each represent a failure alternative strategy.Each failure has a corresponding failure alternative strategy variable (failure substitution
Strategy value).Therefore, if gearbox control detects a failure such as 1 solenoid valve failure (clutch solenoid valve of clutch
Failure will lead to the clutch and not be available).According to the failure alternative strategy defined to 1 solenoid valve failure of clutch are as follows: beat
Trouble light is opened, DCT shift mode is cancelled, shields gear on axis 1.After so 1 solenoid valve failure of clutch determines generation, last
Failure substitute variable can be decomposed, export corresponding 3 failure alternative strategies to other modules.It is realized by other modules
3 failure alternative strategies, when ensureing that 1 solenoid valve failure of clutch occurs for gearbox, vehicle can be travelled, and can remind and drive
The person of sailing repairs to the shop 4S.
Step S5): during gearbox controller executes the alternative strategy, gearbox controller real-time monitoring gearbox
Whether fault-signal disappears, if detecting, fault-signal disappears, and troubleshooting and communication module are set according to config failure attribute
The fail-safe knock-on time set carries out failure debounce, judges that executing the alternative strategy after fault-signal disappears executes the time
Whether it is more than that fail-safe is bounced the time, if the alternative strategy executes the time to be not above fail-safe anti-after fault-signal disappearance
The time is jumped, then the gearbox controller will not cancel alternative strategy and continue to execute alternative strategy, if in fault-signal
The alternative strategy execution time is more than that fail-safe is bounced the time after disappearance, then the failure after meeting failure debounce time
Processing and communication module just exit failure alternative strategy or the alternative strategy exit criteria according to the setting of config failure attribute moves back
Alternative strategy out, troubleshooting and communication module exit substitution plan according to the alternative strategy exit criteria of config failure attribute setting
Slightly method particularly includes: the substitution whether front gear box meets the setting of config failure attribute is worked as in troubleshooting and communication module judgement
Tactful exit criteria.Failure alternative strategy exit criteria be all it is in a safe condition in DCT gearbox, exit in these states therefore
Barrier alternative strategy can guarantee vehicle safety.Failure alternative strategy exit criteria can have a condition, meet the condition, that is, meet
Failure alternative strategy exit criteria, failure alternative strategy exit criteria can also have multiple conditions, meet all conditions, just meet
Failure alternative strategy exit criteria.In the present embodiment, the failure alternative strategy exit criteria includes under gearbox control
Electricity, transmission regime open simultaneously one or more of two clutches disengagement simultaneously in N grades, two clutches.It is described
Three conditions can be used as the failure alternative strategy exit criteria in any combination.As long as meeting the exit criteria, gearbox
Controller can exit the alternative strategy.If meeting the alternative strategy exit criteria, gearbox controller can be exited and be replaced
Generation strategy allows gearbox to restore normal, if being unsatisfactory for the alternative strategy exit criteria, even if fault-signal disappears, and speed changer
Controller still will continue to execute alternative strategy.Certainly, some failures on vehicle driving safety influence and it is little, can be not required to move back
Condition out, after failure vanishes, after meeting failure debounce time, so that it may exit failure alternative strategy.Such as back-up lamp after
Apparatus failure.
The troubleshooting and communication module judge that the alternative strategy execution time is executed after fault-signal disappears is
The method of the no fail-safe knock-on time more than the setting of config failure attribute is also to be obtained using winding cycle calculations, avoids timing
Device overflows, and is by setting master timer and the fail-safe of setting knock-on time difference validity, to judge in fault-signal
Executed after disappearance the alternative strategy execute the time whether be more than the setting of config failure attribute the fail-safe knock-on time.
It comprises the concrete steps that: timer setting is circular for that can generate in specific time period, in timer operational process, failure
It disappears, when the fail-safe knock-on time of config failure attribute setting is added to form new fail-safe knock-on with current timer value
Between, the difference of timer value and new fail-safe knock-on time between the two is signed number evidence, in timer before occurring
When, before the fail-safe knock-on time completes, the difference of the timer value and new fail-safe knock-on time are negative value,
After the completion of the fail-safe bounces the time, the difference of timer value and new fail-safe knock-on time become 0 or positive value, generation
Difference described in table is effective, in the timer after occurring, before the fail-safe knock-on time completes, and new fail-safe knock-on
Time can equally be greater than timer value, therefore described after occurring, before the fail-safe knock-on time reaches, the timing
Device value and the difference of fail-safe knock-on time are similarly negative value, after the completion of the fail-safe bounces the time, the difference
Become 0 or positive value, it is effective to represent the difference, when the difference is effective, it is determined that hold after fault-signal disappearance
The row alternative strategy executes the fail-safe that the time is more than the setting of config failure attribute and bounces the time.
The failure relevant information status data is updated to the gearbox control in the troubleshooting and communication module
In device memory processed.If a fault-signal changes, the troubleshooting and communication module can be by the gearbox controls
Device storage failure categorical data processed is updated；
External equipment obtains fault type from the gearbox control by the high-speed CAN bus, according to setting
State definition, parse fault type, according to defined failure number and corresponding failure code table, inquire to obtain failure
Code；
It is effective that above-mentioned steps in the present invention, which are each described fault-signal,.The event of each fault-signal
Barrier alternative strategy execution is not interfered between each other.And the corresponding alternative strategy of one fault-signal exits, no
Influence the failure alternative strategy of other fault-signals.
Under the premise of guaranteeing safety traffic, failure is quoted, reminds driver vehicle to break down, is examined
It looks into, more meets customer demand.
