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.There are one corresponding failure alternative strategy variable, (failure substitutes each failure
Strategy value).Therefore, if gearbox control detects a failure such as 1 solenoid valve failure (clutch solenoid valve of clutch
Failure can cause the clutch that can not use).Failure alternative strategy according to being defined to 1 solenoid valve failure of clutch is：It beats
Trouble light is opened, cancels DCT shift modes, 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, with ensure gearbox occur 1 solenoid valve failure of clutch when, vehicle can travel, and can remind and drive
The person of sailing repairs to 4S shops.
Step S5)：During gearbox controller performs the alternative strategy, gearbox controller monitors gearbox in real time
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 put carries out failure debounce, judges that performing the alternative strategy after fault-signal disappears performs the time
Whether it is more than that fail-safe is bounced the time, if the alternative strategy performs 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 failure debounce time is met
Processing and communication module just exit failure alternative strategy or are moved back according to the alternative strategy exit criteria that config failure attribute is set
The alternative strategy exit criteria for going out alternative strategy, troubleshooting and communication module according to the setting of config failure attribute exits replacement plan
Slightly specific method be：Troubleshooting and communication module judge whether meet the replacement of config failure attribute setting when front gear box
Tactful exit criteria.Failure alternative strategy exit criteria is all in a safe condition in DCT gearboxes, and event is exited in these states
Barrier alternative strategy can guarantee vehicle safety.Failure alternative strategy exit criteria can meet the condition, that is, meet there are one condition
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 is included 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 meet 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 perform alternative strategy.Certainly, some failures on vehicle driving safety influence and it is little, can be not required to move back
Go out condition, after failure vanishes, after failure debounce time is met, it is possible to 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 performed 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 knock-on time difference validity of setting, to judge in fault-signal
The alternative strategy is performed after disappearance and performs whether the time is more than that the fail-safe that config failure attribute is set is bounced the time.
It comprises the concrete steps that：Timer is set as to generate in specific time period it is circular, 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, timer value is signed number evidence with the difference of new fail-safe knock-on time between the two, in timer before occurring
When, before the fail-safe knock-on time completes, the timer value and the difference of new fail-safe knock-on time are negative value,
After the completion of the fail-safe bounces the time, timer value and the difference of new fail-safe knock-on time become 0 or positive value, generation
Difference is effective described in table, in the timer after occurring, before the fail-safe knock-on time completes, and the knock-on of new fail-safe
Time can equally be more 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 held after fault-signal disappearance
The row alternative strategy performs the fail-safe knock-on time that the time is more than the setting of config failure attribute.
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 by the high-speed CAN bus from the gearbox control, 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 to fault-signal each described that above-mentioned steps in the present invention, which are,.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 ensureing to drive safely, failure is quoted, driver vehicle is reminded to break down, is examined
It looks into, more meets customer demand.
