Most of the traditional fuel vehicles at present realize the power supply of the whole vehicle electric load and an electric network by directly driving a generator through an engine, and charge a low-voltage 12V storage battery serving as a standby power supply. Compared with an old traditional generator, the generator is generally communicated with the controller through the LIN bus, the target generating voltage can be flexibly adjusted and controlled according to specific working conditions and the state of the storage battery, and power generation on demand is achieved so that the oil consumption of the whole vehicle is reduced.
In consideration of oil consumption, a current control strategy of the generator is generally designed to maintain a State of Charge (SOC) of a storage battery near a target value of 80% -85%, the SOC of the storage battery is in dynamic change according to a working condition, and long-term underfill of the storage battery may aggravate a vulcanization reaction of a battery panel, accelerate aging of the storage battery, and shorten a service life.

FIG. 1 is a flow chart illustrating a method of controlling a generator according to an exemplary embodiment. The control method of the generator may be executed by a controller capable of controlling the generator in the automobile. Referring to fig. 1, the method for controlling the generator may include the following steps:
and step 110, acquiring multiple entry judgment data from the moment the generator exits the last storage battery refreshing mode.
The entry judgment data comprises accumulated charge and discharge amount of the storage battery, accumulated times of setting a cycle flag bit of the working condition of the automobile and accumulated duration of a refresh mode of the non-activated storage battery, and each entry judgment data corresponds to one entry judgment condition.
The storage battery Refresh mode is a storage battery Refresh mode, which is a functional mode that can delay aging of the storage battery and prevent the vulcanization phenomenon of the storage battery.
The entering judgment data is obtained by integrating or counting a certain index from the completion of the last storage battery Refresh mode to the current time, and when the entering judgment data is obtained through integration or counting, the entering judgment data can be written into an EEPROM of the EMS controller in real time to prevent power loss, so that the entering judgment data can be obtained from the EEPROM.
Specifically, the unit of the battery accumulated charge and discharge amount GenCtl _ qBattConsum may be Ah, which may be obtained by integrating the absolute value of the battery charge and discharge current ispd _ i _ lvBat _ a from the completion of the last battery Refresh mode to the present time.
In one embodiment of the present application, the cumulative number of times of setting the cycle flag bit of the vehicle operating condition is any one of the following: the accumulated times of setting a complete driving cycle completion flag bit and the accumulated times of setting a complete warming cycle completion flag bit.
The driving cycle and the warming cycle belong to the cycle of the working condition of the automobile. From the completion of the last time of the Refresh mode of the storage battery, setting a driving cycle completion flag ispd _ bDrvCycReach to be 1 every time a complete driving cycle is completed; every time a complete warm-up cycle is completed, the warm-up cycle completion flag ispd _ bWarmupCycReach is set to 1. Every time a complete driving cycle completion flag ispd _ bdrvucch is set to 1 or a complete warming cycle completion flag ispd _ bwarmupcychread is set to 1, the corresponding cumulative number of times is increased by 1. The number of times the driving cycle completion flag ispd _ bdrvcycrech is set is counted, and the cumulative number of times GenCtl _ ctdrvcyclc for setting a complete driving cycle completion flag can be obtained.
Starting timing from the time when the last battery Refresh mode is completed, the accumulation duration GenCtl _ tBattRefreshOffTime of the inactive battery Refresh mode after the last battery Refresh mode is completed can be obtained.
An entry judgment data is used to judge whether an entry judgment condition corresponding to the entry judgment data is satisfied.
The entry judgment condition corresponding to the entry judgment data of the accumulated charge and discharge capacity of the storage battery can be that the accumulated charge and discharge capacity GenCtl _ qBattConsum of the storage battery is more than or equal to a threshold value obtained by checking a MAP table according to the actual SOC electric quantity ispd _ pct _ lvBatSOC of the storage battery; the entry judgment condition corresponding to the entry judgment data of the cumulative number of times for setting a complete driving cycle completion flag bit is that the cumulative number of times for setting a driving cycle completion flag bit GenCtl _ ctdrvcycle is greater than a predetermined cumulative number threshold (e.g., 100) from the completion of the last battery Refresh mode to the current time; the entry determination condition corresponding to the entry determination data of the accumulated time length of the inactive storage battery Refresh mode may be that the accumulated time length GenCtl _ tbattrefreshofftimei of the inactive storage battery Refresh mode is greater than a first time length threshold (e.g., 36000 seconds) from the time when the last storage battery Refresh mode is completed to the current time.
In one embodiment of the application, before obtaining entry judgment data items from when the generator exits the last battery refresh mode, the method further includes:
and judging whether the engine of the automobile is in a starting state, wherein the acquisition of a plurality of items of entering judgment data from the moment the motor exits from the latest storage battery refreshing mode is carried out under the condition that the engine of the automobile is in the starting state.
Specifically, when the vehicle system status flag ispd _ stSub = Drive, it may be determined that the engine of the vehicle is in a start state.
In the embodiment of the present application, the calculation of the subsequent step is performed only when the engine of the automobile is in a start state.
And step 120, if the entry judgment condition corresponding to the at least one entry judgment data is satisfied, determining that the storage battery refresh mode needs to be entered.
When any one of the three entry determination conditions corresponding to the three entry determination data is satisfied, it may be determined that the Refresh mode of the storage battery needs to be entered.
FIG. 2 is a flowchart illustrating details of steps 110 and 120 of FIG. 1 according to an exemplary embodiment. Referring to fig. 2, step 110 and step 120 may specifically include the following steps:
and step 110', if the request flag bit for entering the storage battery refreshing mode is not in a set state, acquiring a plurality of entry judgment data from the time the generator exits the last storage battery refreshing mode.
If GenCtl _ bBattRefreshReqOld = false, entry judgment data is acquired. The GenCtl _ bBattRefreshReqOld here is a request flag bit for entering the storage battery refresh mode used in the last round of determination whether to enter the storage battery refresh mode, where the GenCtl _ bBattRefreshReqOld = false represents that the request flag bit for the storage battery refresh mode is not in a set state, and only if the request flag bit for the storage battery refresh mode is not in the set state, it can represent that the storage battery refresh mode is not entered currently, and subsequent operations such as obtaining entry determination data can be performed.
And 120', if the entry judgment condition corresponding to the at least one entry judgment data is satisfied, setting a flag bit of a request for entering the storage battery refresh mode to determine that the storage battery refresh mode needs to be entered.
Setting the position of the request mark for entering the storage battery Refresh mode GenCtl _ bBattRefreshSet to true means that the storage battery Refresh mode needs to be entered.

Each of the engine state data corresponds to an activation judgment condition.
In one embodiment of the present application, the at least one item of engine state data includes an engine water temperature and a time period for completion of engine starting, the activation determination condition corresponding to the engine water temperature is that the engine water temperature is higher than a predetermined engine water temperature threshold, and the activation determination condition corresponding to the time period for completion of engine starting is that the time period for completion of engine starting is higher than a predetermined time period threshold.
For example, the activation determination condition corresponding to the engine water temperature may be specifically that the engine water temperature ispd _ t _ engClnt _ degC is higher than 60 ℃. The setting of the flag bit is performed upon completion of the engine start, and therefore, the activation determination condition corresponding to the time period for completion of the engine start may be that the setting time of the engine start completion flag bit ispd _ flg _ engstrtcompt exceeds 5s.
And 140, if the storage battery refreshing mode is required to be entered and the activation judgment conditions corresponding to the various engine state data are met, activating the storage battery refreshing mode of the generator to control the generator to charge the storage battery with the target power generation voltage higher than the standard voltage of the storage battery.
For example, the standard voltage of the battery may be 12V; after the storage battery refresh mode of the generator is activated, the generator is controlled to charge the storage battery at a target generation voltage GenCtl _ uVltgSetP which is higher than 12V. The target generation voltage GenCtl _ uVltgSetP may be greater than or equal to 14.3V, and the battery may be fully charged by controlling the generator to charge the battery with a generation voltage of 14.3V.

Specifically, the actual electric quantity of the storage battery, namely the actual SOC electric quantity of the storage battery ispd _ pct _ lvBatSOC, and the activation time of the storage battery refresh mode is the accumulated running time of the storage battery refresh mode, genCtl _ tbattreflife.
Each set of exit judgment data may include one or more items of data. Specifically, the first set of exit determination data may include the actual SOC electrical quantity ispd _ pct _ lvBatSOC of the battery, and the exit determination condition corresponding to the set of exit determination data may be that the accumulated time period that the actual SOC electrical quantity ispd _ pct _ lvBatSOC of the battery is higher than the first preset electrical quantity threshold (e.g., 95%), and that the actual SOC electrical quantity ispd _ pct _ lvBatSOC of the battery is higher than the first preset electrical quantity threshold exceeds the second time threshold (e.g., 36000 seconds), and the accumulated time period may be written into the EEPROM of the EMS controller in real time to prevent power-down loss, and may be cleared when the actual SOC ispd _ pct _ lvBatSOC of the battery is lower than the second preset electrical quantity threshold (e.g., 90%).
The second group of exit determination data may specifically include an activation duration GenCtl _ tbattrefrestime of the battery refresh mode, and the exit determination condition corresponding to the group of exit determination data may be that the activation duration GenCtl _ tbattrefrestime of the battery refresh mode exceeds a third duration threshold (e.g., 14400 seconds). When the storage battery Refresh mode of the generator is activated, namely the activation flag bit GenCtl _ bBatttRefresthActVold of the storage battery Refresh mode obtained by the previous calculation is in a set state, and the actual generating voltage GenCtl _ uVltgSetP of the generator is not less than 14.3V to start timing, the activation duration GenCtl _ tBatttRefreshTime of the storage battery Refresh mode is written into the EEPROM of the EMS controller in real time to prevent power-off loss, and when the storage battery Refresh mode exits, the activation duration of the storage battery Refresh mode is automatically cleared.
The third set of exit determination data may specifically include an activation duration GenCtl _ tbattrefrestime of the battery refresh mode and an actual SOC electric quantity ispd _ pct _ lvBatSOC of the battery, and the exit determination condition corresponding to the set of exit determination data may specifically be that the actual SOC electric quantity ispd _ pct _ lvBatSOC of the battery is higher than a third preset electric quantity threshold (e.g., 95%), and the activation duration GenCtl _ tbattrefrestime of the battery refresh mode exceeds a fourth time threshold (e.g., 3600 seconds).
The activation of the Refresh mode of the storage battery can be determined according to the state of the activation flag genttl _ bBattRefreshActvOld of the Refresh mode of the storage battery obtained in the previous calculation.
The fourth group of exit determination data may include a generator fault information flag GenCtl _ bCtlActGEN, and the exit determination condition corresponding to the group of exit determination data may specifically be a setting of the generator fault information flag GenCtl _ bCtlActGEN.
And step 160, if the exit judgment condition corresponding to at least one group of exit judgment data is satisfied, determining that the storage battery refresh mode needs to exit, and exiting the storage battery refresh mode of the generator.
When any one of the four exit determination conditions corresponding to the four sets of entry determination data is established, it may be determined that the storage battery refresh mode needs to be exited.
Fig. 4 is a flowchart illustrating details of steps 140 and 160 of fig. 3 according to an example embodiment. Referring to fig. 4, step 140 and step 160 may respectively include the following steps:
and 140', if the request flag bit for entering the storage battery refresh mode is in a set state, the request flag bit for exiting the storage battery refresh mode is not in the set state, and the activation judgment conditions corresponding to each item of engine state data are all satisfied, activating the storage battery refresh mode of the generator.
When it is detected that the position GenCtl _ bBattRefreshSet of the request mark for entering the storage battery Refresh mode is set to true, and the position GenCtl _ bBattRefreshReset = false of the request mark for exiting the storage battery Refresh mode is determined, and activation determination conditions respectively corresponding to the water temperature of the engine and the time length of the completion of the starting of the engine are all met, the activation mark position GenCtl _ bBattRefreshActv of the storage battery Refresh mode can be set.
As can be seen from the above condition for activating the battery refresh mode of the generator, if the battery refresh mode request flag bit GenCtl _ bbattrefreset = true exits, the battery refresh mode of the generator cannot be activated regardless of the state of entering the battery refresh mode request flag bit GenCtl _ bbattrefresset.
And step 160', if the exit judgment condition corresponding to at least one group of exit judgment data is satisfied, setting the request flag bit for exiting the storage battery refresh mode to determine that the storage battery refresh mode needs to be exited.
When any one of the four exit judgment conditions corresponding to the four sets of entry judgment data is satisfied, it is determined that the storage battery refresh mode needs to be exited by setting the exit storage battery refresh mode request flag bit GenCtl _ bbattrefreshrereset to true.
When GenCtl _ bbattrefreactiv = true, the generator is controlled to generate power at a target generation voltage of 14.3V.
As can be seen from the above, the specific index used for determining that the battery refresh mode needs to be exited may include: the generator fault information flag GenCtl _ bClActGEN, the Refresh mode activation flag GenCtl _ bBattRefreshActVold obtained in the previous round of calculation, the actual generation voltage GenCtl _ uVltgSetP of the current generator, and the actual SOC electric quantity ispd _ pct _ lvBatSOC of the storage battery.
