The method for operating and controlling vehicle power assembly according to the present invention shown in Fig. 1 is related to mixed with manual transmission
Power car is closed, wherein, driver, which performs, to shift gears and operates clutch by driver.Depending on signalling technique detects operation shape
State, vehicle is run mixed power plant in a manner of being converted between internal combustion engine and electric running pattern.
In order to perform starting process, electric running pattern is enabled when detecting all lower column signals：Identification represents vehicle
The signal of ready state is travelled, such as by the way that ignition key is inserted into ignition switch：" Key-On (starting) ", and connect
Ignition system：" connection ignition system ", " being linked into neutral ", " manipulation foot brake ", " vehicle velocity V=0Km/h " and " vehicle parameter
Normally ", i.e. in the absence of the vehicle operating modes to be opposed with electric running pattern.
The gear locking of speed changer is carried out for quiescing when enabling electric running pattern.
As an alternative, if closing internal combustion engine in stop phase in engine start period out of service, and engine opens
Move precondition out of service to exist, then enable electric running pattern automatically to start vehicle.
If on the contrary, above-mentioned precondition is not met, then send electric running pattern not enabled is prompted to driving
Member.In this case, driver can start vehicle under internal combustion engine driving mode by convention.Electric running pattern opens
With especially with critical vehicle parameter oppose, such as critical accumulator electric-quantity state SOC (State Of Charge (charging shape
State)), the critical-temperature of cooling water, engine oil or air-conditioning etc..
Enabling for electric running pattern can also it is expected for example to carry out by manipulating switch according to driver.
When enabling electric running pattern, the motor of the transmission output shaft of speed changer preferably with vehicle hybrid power device
It is connected.Due to transmission gear locking, so speed changer can not possibly be passed through for driver under electric running pattern
Gear level is linked into gear.
If accelerator pedal position corresponds to torque request Mde-Drive(it is less than or equal to, and presetting motor is maximum to be turned round
Square MdEM), and not recognizing controlled clutch, then vehicle is travelled with electric running pattern.Here, the torsion of maximum possible
Square MdEMOperation reserve is changeably matched with to limit the speed under electric running pattern.
Conversely if there is no above-mentioned precondition, then electric running pattern disables.
If in electric running pattern downward driving, then check for the condition of electric operation.If it is present,
Keep electric running pattern.When detecting pilot control clutch or if driver closes electric running by switching
Pattern, then disable electric running pattern.It can be utilized for this and identical switch of electric running pattern is enabled by it.This
Outside, if detecting presetting regulated variable or the parameter with holding electric running pattern opposition, then leave electric running
Pattern.For example, if vehicle velocity V exceedes the maximum possible or optimal limit vehicle velocity V under electric running patterne-Drive-Limit, then
Disable electric running pattern.Here, can ground variable adjustment limit vehicle velocity V relevant with operation reservee-Drive-Limit.In addition, such as
Fruit especially shows critical vehicle parameter, such as critical accumulator electric-quantity state SOC, then disables electric running pattern.
When driver terminates electric running pattern, especially when driver is turned off electric running pattern, can also advise
It is fixed, until ignition key is being inserted into ignition switch " Key-On " (referring to above-mentioned) next time and existed as described above
" in the case of vehicle velocity V=0 ", electric running pattern is just being enabled during other preconditions next time or when stopping.
When electric running pattern disables, the locking of speed changer is opened, vehicle internal combustion engine is opened in pilot control clutch
Beginning work.Here, driver's prompting is provided, to be linked into the gear for being matched with vehicle velocity V in gearbox, such as " controlled clutch,
Then it is linked into numbering X gear ".To detection gear internal combustion engine can be made to reach related rotating speed by travel speed.Pass through release
Clutch pedal, clutch closure.Present driver is in internal combustion engine driving mode downward driving, as band manual transmission and internal combustion
Traditional PKW of machine is the same.
If vehicle enters halted state and automatic engine stop mode has enabled, then driver can pass through behaviour
Vehicle is gone to electric running pattern (such as referring to " Key-On " above) by vertical brake pedal.As an alternative, electric running pattern is being sent out
Motivation stop phase enables automatically.
Required letter can be handled by using the control device being for example integrated in vehicle engine control unit (ECU)
Number, these signals pass through bus system (such as by CAN, Chinese, controller local area network) or straight by another control unit
Connected sensor or transmitted by other so-called controllers.For directly disabling electric running pattern, such as clutch
Pedal signal, accumulator electric-quantity state (SOC) or signal " vehicle brake (foot brake) not enabled " or possible event
It is probably conclusive to hinder information.
Fig. 2 flow chart supplements Fig. 1 and shows flow from internal combustion engine drive vehicle mode conversion to electric running pattern.Therefore,
The internal combustion engine drive vehicle pattern that Fig. 2 flow imports after Fig. 1 deactivation electric running pattern.In order to go to electric walking
The conversion of pattern is sailed, electric running pattern can be converted into the first step by checking whether.In order to perform conversion, lower column signal
Must all exist：" Key-On ", " clutch does not manipulate ", " vehicle parameter is normal ", " internal combustion engine has accessed ", " accelerator pedal position
Put and correspond to torque request Mde-Drive(it is less than or equal to presetting motor maximum torque MdEM) ", " vehicle velocity V is not less than pole
Limit vehicle velocity Ve-Drive-Limit”.If these preconditions are not present, then keep internal combustion engine drive vehicle pattern.It is if opposite above-mentioned
Precondition is present, then carries out the display to driver to switch to speed changer neutral gear position.Check in the next step,
Whether speed changer is in neutral gear position.If it is the case, so enable the locking carried out to speed changer and enable electronic
