Brief description of the drawings
The accompanying drawing shown according to the multiple embodiments of the present invention is simplified by following explanation and wherein according to further feature of the present invention Obtain.In figure：
Fig. 1 shows the indicative flowchart according to the inventive method with first embodiment；
Fig. 2 is indicative flowchart of the supplement according to Fig. 1 method；
Fig. 3 shows the indicative flowchart according to the inventive method with second embodiment.
Embodiment
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 Driving mode.Here, internal combustion engine can be closed or keep its operation.Subsequent operation for example according to Fig. 1 flow, enables electric walking Sail pattern (referring to mark (*)).
The extension of theory described according to Fig. 1 and Fig. 2 method is shown with second embodiment in figure 3.According to Fig. 3 side Method is based on the clutch using local automation.It can realize herein unrelated with controlled clutch pedal from main clutch behaviour Control.Clutch is separated by clutch actuating mechanism in controlled clutch pedal, become so that driver finds same traditional manual The same clutch characteristics of fast device.
Another process applicable is to add to integrate or use available control unit data, to be stepped in not controlled clutch Clutch is targetedly manipulated in the case of plate.Manipulation clutch can be understood as targetedly separating or closing clutch herein Device and by clutch keep in this state.Therefore, such as hydraulic operated clutch pedal signal and clutch actuator, It is incorporated into so as to which clutch will be enabled on data technique in the range of controller.
The flow chart shown in Fig. 3 is illustrated below by the difference of the flow with respect to Fig. 1.By according to Fig. 3 Method in autonomous manipulation clutch can obtain other running statuses, so as to can be started all the time under electric running pattern (step A).Under electric running pattern, each related transport condition can be by corresponding to torque request Mde-DriveAcceleration Pedal position, in view of possible motor maximum torque MdEMWith limit vehicle velocity Ve-Drive-LimitIn the case of obtain.In electric walking When sailing pattern and disabling, automatic controlled clutch (step B) and start internal combustion engine.Another difference is that if there is carrying above The condition (referring to step A " Key-On " above) arrived, with regard to carrying out automatically from internal combustion engine drive vehicle pattern to electric running pattern Convert (step C).It is performed automatically in order to disengage the manipulation to clutch needed for internal combustion engine when gear is linked into speed changer, from The dynamic gear for performing locking speed changer selects and enabled electric running pattern (step D).In addition can targetedly import and Terminate so-called sliding mode (close internal combustion engine and separate clutch).
In order to realize the method according to Fig. 1 to Fig. 3, at least one motor connection to for example traditional manual transmission.Its It may be embodied as dual-shaft variable device or other more shaft transmissions.In order to engage motor, it is preferably provided with engaging executing agency, by this Engagement executing agency motor alternatively can couple or disengage with two gear shafts of speed changer.Switch unit is set for this, led to Cross the switch unit and obtain corresponding switching state using executing agency (such as switching distant bar) is engaged.In engagement executing agency and change Between the above-mentioned autonomous clutch actuating mechanism of fast device kobold loose joint speed changer can be closed under collaboration situation depending on operation reserve The first speed gear axle or second gear axle.Can be by the manipulation for control device by the way that motor is connect under driving mode First or the second gear axle for being bonded to speed changer are tactful to generate optimal traveling.It is this herein to be engaged through enabling engagement execution machine Structure is realized.First or second gear axle is bonded to motor or gear shaft is not attached to the switch logic of motor and operation reserve and had Close.In the state of vehicle stops or do not enabled, other circuit connections are feasible.Engagement between motor and speed changer is preferred Carried out on transmission input shaft or transmission output shaft.
In the first state, motor is bonded to transmission output shaft by engaging executing agency.Here, enabling electric walking Pure electric drive is realized by motor when sailing pattern, at the same time, the gear level of speed changer is in neutral gear position.Driver can be with By accelerator pedal, predetermined torque asks Md with corresponding to accelerator pedal positione-Drive, so as to depend on available and install Electric energy can for example be travelled with 40km/h speeds.The advantages of driving vehicle via transmission output shaft by motor is Ke Yishi Now it is driven in a manner of the traction loss not over internal combustion engine.In addition, when driver switches transmission gear, work as change Switch speed change un-interrupted for drawing by the way that motor to be bonded to transmission output shaft and can realize during fast device clutch separation The moment of torsion of device is supported, is thus not only increased traveling dynamic and is also improved driving comfort.
In the second condition, when electric running pattern enables, motor is by engaging executing agency and transmission input shaft It is connected.It is possible thereby to realize the gearratio of the transmission input shaft in manual transmission.It is corresponding by being linked into the transmission Gear, moment of torsion can be transferred to transmission output shaft.By selecting the not simultaneous interpretation between motor driving shaft and transmission input shaft Dynamic ratio can reach the speed for being for example up to about 140km/h.By selecting between motor driving shaft and transmission output shaft not As little as about 40km/h speed can be realized with gearratio.In addition, it can realize that mixing is dynamic when having engaged transmission input shaft The power method of operation.Internal combustion engine come power-assisted, energy regenerating or can be made by motor by the manipulation to transmission control unit Load point improves.
Under neutral position state, when electric running pattern enables, motor is by engaging executing agency and transmission input shaft Disengaged with transmission output shaft.The state can or vehicle very high in rotating speed it is auxiliary for running as defencive function when stopping Help unit.
