Description
Technical field
Invention relates to a kind of method that is used to move hybrid vehicle, and this automobile has an actuating device that has at least two different dynamic devices, and wherein at least one motor can be used as the engine installation operation with the combustion engine that at least one has Catalyst.Actuating device has at least one motor and at least one combustion engine as engine installation, and wherein hybrid vehicle can just be used motor according to running condition, just uses combustion engine, perhaps moves with motor and combustion engine.
These different possibilities are understanded by described expression beginning.
Technical background
For common automobile, this automobile only has a combustion engine (being also referred to as explosive motor), carries out the startup of combustion engine as dilatory the startup when the startup that starts cold combustion engine just first.This means: the actuator of automobile is dilatory to an actuator rotating speed with combustion engine, and combustion engine is started.After starting, explosive motor immediately one is attached troops to a unit in the Catalyst heating of combustion engine.This especially also when tickover, carry out very soon, so Catalyst reaches the inversion temperature that it must be wanted rapidly.Tickover forms by following: driver's great majority are not directly to make automobile sport after starting, but for example also put into gear, and fasten seat belts or this class thing.
A kind of actuating device of known hybrid vehicle has a motor at least as engine installation and at least one has the combustion engine of Catalyst, in this automobile when pure electricity starts (for example based on good battery of charging and suitable external temperature, for example 20 ℃), if there is not the startup of combustion engine just can not implement function (heatable catalytic converter).If a kind of attached controller is because different condition and the operation between the electricity starting period has been proposed higher moment requirement, though so must starting apparatus combustion engine, thus make combustion engine participate in the moment requirement that improves immediately.So perhaps combustion engine just is not said such, if also just be in tickover in short time, but be used to support the operation of hybrid vehicle immediately, therefore owing to also do not reach the Catalyst inversion temperature, just there is the nuisance of uncontrollable quantity to enter into environment as waste gas.The known control setup of hybrid vehicle thereby stoped the pure electricity when cold combustion engine to start.
Summary of the invention
Method according to invention, wherein carry out the starting of electricity at least of hybrid vehicle during when the starting first of the hybrid drive that carries out under the situation of cold combustion engine a kind of, and it is before starting, make internal combustion engine start simultaneously and afterwards, and an internal combustion operation in service of separating with the electricity operation of motor, be used for heatable catalytic converter, therefore shortcoming recited above does not just occur, this is because of for example pure automobile that drives when starting first electricly, the regulation like this that puts into operation then of combustion engine: it is helpless to drive, but in the short time Catalyst is being heated to inversion temperature as much as possible.Therefore the operation scheme of motor and combustion engine is separated, thereby with remaining may be irrespectively to the motor requirement, they can not allow under a stable condition or be to allow limitedly, and such purpose is always arranged, and promptly at first Catalyst will be heated to inversion temperature with regard to combustion engine.If carried out like this, combustion engine just can be finished its remaining task so.Therefore combustion engine does not help the operation of hybrid vehicle and/or other operation task, if do not realize primary objective like this, just as quickly as possible Catalyst is heated to inversion temperature.Do not allow to reach all situations of this target or be prevented from, perhaps just in certain limit, allow, to reach described target.This form of implementation thereby shown: what so-called " separating " internal combustion operation is.If hybrid vehicle is not purely to be driven when starting first, but supports by combustion engine electricly, so also there is accordingly action according to invention.If passed through a period of time after " rotation ignition key " and starting, its (with later time in case of necessity) can be used to internal combustion separately and moves so.
According to a kind of improvement design plan of the present invention, at the internal combustion that the separates combustion engine that makes in service at tickover.The pure hybrid vehicle that makes starts electricly when starting first thus, and combustion engine is helpless to the driving of hybrid vehicle.Make the idling for internal combustion engine running or rather, so that reach the inversion temperature of Catalyst as quickly as possible.If reached inversion temperature, the internal combustion operation that separates so just finishes and changes a kind of normal internal combustion operation over to, and depend on the operation strategy of hybrid vehicle controller this moment, and combustion engine is just carried out its basic task.
A kind of preferred form of implementation of the present invention has been stipulated: at the internal combustion that the separates combustion engine run with load that makes in service.Combustion engine is coupled with certain, especially constant load moment or add that certain load moment changes, yet always so do not disturb or be the heating of fast speed as far as possible of not obvious interference Catalyst.The loading of combustion engine also cause smoothness of operation improvement, this performance is to be worth pursuing in pure when starting electricity of hybrid vehicle especially.
Stipulate according to a kind of improvement design plan of the present invention: adjust rotating speed ground and carry out the internal combustion operation.This rotating speed adjustment is realized by a control setup (for example a kind of controller) of hybrid vehicle.
Stipulate according to a kind of improvement design plan of the present invention: the load of determining is carried out by the auxiliary device of driving hybrid vehicle and/or by a support motor ground operation hybrid vehicle.Combustion engine is just supported electrical motor then under the situation of back, in other words, move hybrid vehicle by two machines, wherein, in order to realize, just make Catalyst Fast Heating ground support motor based on the internal combustion operation of combustion engine that separates according to target of the present invention.Therefore the moment that is provided by combustion engine or just should not have change ground to depend on the desirable setting of driver mutually.If the driver for example wants to quicken greatly when starting, yet motor can not provide necessary moment separately, combustion engine provides an additional moment so, but not scale to require, but might be insufficient scale, the separately internal combustion that is used for can implementing best according to invention moves, so that heatable catalytic converter.
Stipulate according to a kind of improvement design plan of the present invention: combustion engine is by starting by means of the dilatory of a kind of starter motor or by the slip by means of motor.Under latter instance, combustion engine can be connected with motor by a power-transfer clutch, thereby the rotating speed that reaches hope is used for starting apparatus combustion engine.This can be by power-transfer clutch complete closure or depend on running condition, also carry out like this, power-transfer clutch is moved in sliding and running.
Especially reach 300 to 600 rev/mins when rotating speed of motor, especially 400 to 500 rev/mins the time, perhaps during the such sliding and running of power-transfer clutch, combustion engine is connected with motor is used for its startup.This rotating speed is higher than the known starter gear rotating speed of known devices at that time significantly, and has reached a kind of good coordination compromise between energy input, exhaust gas properties and/or starting characteristic.
A kind of improvement design plan regulation of the present invention: combustion engine is moved like this, to satisfy the heat request that adds of Catalyst.The triggering of combustion engine that is to say the heating of at first paying close attention to Catalyst and prepares heat for this reason.All the time should guarantee the heat request that adds of Catalyst.
The present invention relates to a kind of actuating device in addition and is used to move hybrid vehicle, in particular for implementing method recited above, this device has at least two different engine installations and a control setup, wherein as engine installation, have at least one motor and have the combustion engine of Catalyst, and control setup depends on that the running state of hybrid vehicle triggers wherein at least one engine installation with at least one.Stipulated simultaneously: when the hybrid vehicle that control setup carries out when a kind of cold combustion engine the time starts first, trigger motor at least and be used to make hybrid vehicle to realize the electricity starting at least; And before starting, simultaneously or afterwards control setup makes internal combustion engine start, and operate to heatable catalytic converter with a kind of internal combustion that separates with motor and move.Here also understand " the internal combustion operation that separates " again like this: this operation only is used for Fast Heating Catalyst best.Here can not understand so again: carry out the heating of Catalyst this " also " in service, yet diverse target is very important in principle.
According to a kind of improvement design plan of above-mentioned actuating device, engine installation is realized with parallel mixed-arrangement or axle mixed-arrangement.In parallel mixed-arrangement, combustion engine can be by a cut-off clutch and motor coupling.In the axle mixed-arrangement, two devices can be by the base (Untergrund) of hybrid vehicle on the contrary, and for example road is coupled.No matter be combustion engine, or motor all is furnished with at least one axle respectively.
In addition advantageously: combustion engine links to each other with motor by cut-off clutch, and motor is connected with a transmission system of hybrid vehicle by a starting clutch.Control setup can trigger cut-off clutch and/or starting clutch, and wherein this considers to carry out according to the thinking ground of invention.

Description of drawings
Accompanying drawing has been represented to be depicted as according to the invention of an embodiment:
Actuating device of figure is as a kind of parallel mixing of the hybrid vehicle that is not shown specifically.
The specific embodiment
Accompanying drawing has been represented a kind of actuating device 1 that is used to move a hybrid vehicle that is not shown specifically.Actuating device 1 is designed to parallel mixing 2.It has two different engine installations 3 and 4, and the drive wheel 7 that has 5, one difies 6 of a change-speed box and be used to drive hybrid vehicle.
Engine installation 3 is designed to combustion engine 8, and it has a Catalyst 9 in the exhaust system that it is not shown specifically.Engine installation 4 is designed to motor 10.Between combustion engine 8 and motor 10, connected a cut-off clutch 11; Between motor 10 and change-speed box 5, be provided with a starting clutch 12.Hybrid vehicle has a control setup 13 in addition, and especially with a kind of form of brain box, its controls and/or regulate combustion engine 8, motor 10, cut-off clutch 11 and starting clutch 12, and the operation that also has other parts in case of necessity.
Can make hybrid vehicle realization startup first subsequently by means of control setup 13, wherein so-called " starting first " is meant the first startup of hybrid vehicle in the circulation of travelling (for example from first " igniting "), combustion engine 8 for example is in cold state in this circulation, in other words, it and the Catalyst 9 that therefore yet comprises do not reach their running temperatures separately, therefore Catalyst 9 does not possess inversion temperature, and therefore just can't handle the exhausted air quantity of the combustion engine 8 of generation, and more nuisance is sent to external environment.If implement above-mentioned startup first, so during starts or afterwards, this starting at first will move by means of motor 10 is pure in an embodiment of the present invention electricly, carry out the closed in short-term of cut-off clutch 11, so combustion engine 8 is drawn high some startup rotating speeds by motor 10.From 400 to 500 rev/mins rotating speed had turned out to be suitable startup rotating speed already.Self-evident, when motor 10 had described rotating speed, that just need make cut-off clutch 11 closed fully.If motor 10 has higher rotating speed, so just make cut-off clutch 11 closure so greatly, to such an extent as to reach described startup rotating speed by sliding and running.After combustion engine 8 starts, cut-off clutch 11 is opened, thereby make combustion engine 8, irrespectively (that is to say especially and motor 10 with remaining transmission system, change-speed box 5 and operation wheel 7 are irrespectively), can carry out its heat run stage along with the heating of Catalyst 9, preferentially carry out with the fastest approach.Driver's hope is for example trampled Das Gaspedal more strongly, also just is transferred to motor 10, and be not transferred to combustion engine 8, like this so that can implement the operation of described internal combustion, so that Fast Heating Catalyst 9 best, it is called " the internal combustion operation that separates with motor " in these application documents.Can alternatively also make the waste heat of combustion engine 8 be used for heating the automotive interior space.Motor 10, especially when the parallel mixing 2 of illustrated embodiment, the propelling vehicle operation, explosive motor then irrespectively and in the present embodiment moves to preferential no-load ground and especially speed adjustment with the transmission system rotating speed, therefore combustion engine 8 for example can be realized 1000 to 1200 rev/mins high rotational speed, and such rotating speed is particularly suitable for heatable catalytic converter 9.The internal combustion that separates operation for combustion engine 8, its condition precedent is: combustion engine 8 is for have enough mass of flywheels from running ability, and preferentially in above-mentioned range of speed, has certain running stability, so that can not disturb the pure driver who travels electricly.
According to another, relate to the operation type of another embodiment, combustion engine 8 is loaded when starting first above-mentioned, be used for the shortening heat operation phase and shorten heating period of Catalyst 9.This has especially also improved the running stability of combustion engine 8.For example load can by as get off to carry out: drive at least one auxiliary device with combustion engine 8, for example hybrid vehicle electrical generator.
Subsidiary or alternatively can also make cut-off clutch 11 in the limited in time hot operation phase, move slidably by means of control setup 13; Producing necessarily on cut-off clutch 11, especially also is constant load moment, and for example 10 to 20Nm.This cut-off clutch moment of combustion engine 8 usefulness helps the driving of automobile energetically, however do not abandon desirable, the internal combustion operation that separates with motor 10.Depend on the situation that each exists, can design cut-off clutch 11 is opened fully, and/or after starting, stop, at this moment cut-off clutch 11 closure fully, for example on the change-speed box center position of change-speed box 5, in other words: combustion engine 8 must be born a corresponding moment.In a word as seen, can finish or shorten the sliding and running of cut-off clutch 11, and can adjust the moment of hope, be used to make the heat operation optimization of explosive motor by the generator operation of motor 10.Usually in a rpm governor, in service moment takes in and pre-control as controlling in advance in the speed adjustment of combustion engine 8 with load moment.
Can design following operation type according to another one embodiment: also before hybrid vehicle starting, motor 10 can be moved when starting clutch 12 is opened, be used for starting apparatus combustion engine 8, thus can be to Catalyst 9 heating.If combustion engine 8 has started, so again cut-off clutch 11 is opened.Has only the starting of just carrying out hybrid vehicle after this.This situation for example produces when following condition: the driver of hybrid vehicle does not start afterwards immediately in insertion " ignition key ".Before the starting and/or during, combustion engine 8 carries out internal combustion operation separately, reaches till the inversion temperature of Catalyst 9 always.
According to according to mode of the present invention, when starting first, can realize combustion engine 8 the bests, the exhaust gas properties that can reappear almost, this is because combustion engine 8 can irrespectively be moved and heats with the transmission system of hybrid vehicle is independent.Therefore combustion engine 8 just should especially support the operation of automobile energetically with higher corresponding to the drive torque of travel situations, prepare if Catalyst 9 has been carried out conversion.Can realize a kind of electricity under a kind of situation of good exhaust gas properties considering in a word, especially also be starting of a kind of pure electricity.
As mentioned above, engine performance by means of invention before the inversion temperature that reaches Catalyst 9 all with driver's hope, and almost irrelevant with the acceleration pedal dynamic.
If being through with, combustion engine 8 moves strategy Catalyst heating strategy in other words according to heat of the present invention, make cut-off clutch 11 partly closed so, closed fully in other words, and combustion engine 8 can, especially support driving with its whole available moment.Open-minded, the special startup triggering of electricity starting load combustion engine 8 operations that strategy makes the branch open shop with described, and cut-off clutch 11 back to back complete closures is implemented and is monitored by means of a kind of higher level's hybrid power control policy.Described control setup 13 is used for this.
Separating the operating advantage of internal combustion except above-mentioned, especially can also carry out at least a diagnosis to combustion engine 8, therefore the motion of automobile is unaffected, and/or does not design with mixed running under certain condition or seldom carry out, for example the promotion stage of combustion engine 8.
According to the present invention, by internal combustion operation that separates and the heating that occurs thereupon, formed a kind of additional degrees of freedom, to guarantee best operation control to Catalyst 9.
Another characteristics of the present invention are, in hybrid vehicle with a motor 10, one with the independently irrelevant pure electricity operation axle of the operation axle of explosive motor on use said method.Move the operation wheel 7 of hybrid vehicle respectively by these.In a kind of such hybrid vehicle motor 10 and combustion engine 8 can " pass through road " in other words the base of hybrid vehicle (Untergrund) connect, just have a kind of so-called axle to mix in this case.The special property of this performance is there is not cut-off clutch 11 in transmission system, and just starting clutch 12 is arranged attaching troops to a unit in the transmission system of combustion engine 8, and wherein the function of described method is finished or implemented to starting clutch 12.By means of a kind of outer starting device, for example a kind of actuator perhaps starts by sliding and realizes starting combustion engine 8 in transmission system, and this slip startup realizes by road.Slip by road starts, and a kind of possible, when the axle that passes through electricity that carries out simultaneously and the torque compensation of motor 10 thereof, makes full use of the kinetic energy of hybrid vehicle by the closure of starting clutch 12.Slip startup by road can only be from making combustion engine 8 realize the some rotating speed enforcement of the starting clutch 12 of startup.
