Description

Be used at the operation method of automobile by oil-engine driven motor
Technical field
The present invention relates to a kind of being used at the operation method of automobile by oil-engine driven motor, and a kind of power supply unit.
Background technique
Modern Internal-Combustion Engine is equipped with so-called starting/stop robot device usually.A kind of like this starting/stop in the robot device regulation automatically break off internal-combustion engine according to certain condition, normally through finishing spray fuel (cut-off fuel just).Usually when parking of automobile, accomplish this end spray fuel.In case the driver wants to continue to go, and this is for example through the operating operation parts, and for example fuel door pedal or clutch pedal show, and then internal-combustion engine starts automatically.This is called in the framework of this invention restarts.
Can adopt diverse ways to realize this restarting.
On the one hand use such certain methods, in these methods by so-called starter or starting arrangement cranking internal combustion engine once more.For this reason, use the favourable small gear starter of a kind of cost usually.Because in the internal-combustion engine that rotates, engagement can not be arranged usually in this case, so it is a prerequisite with the internal-combustion engine parking.Therefore people hope from stop to spray fuel to internal-combustion engine fully the time lag out of service can lack as much as possible, in order that needn't make driver's the hope interest for delinquency of starting once more.
So-called across-the-line starting method is also disclosed on the other hand; In said across-the-line starting method; Inertia run duration at internal-combustion engine just provides favourable mixed gas for starting once more in cylinder, so just can under the situation of not using starter, directly pass through ignition start.Wherein, wash out residual gas exactly, for this reason, particularly improve suction press through opening throttle valve in the internal-combustion engine inertia operation phase in the frequent actual step of carrying out of inertia run duration.Yet in cylinder, improve the instability that air quantity can cause the operation of internal-combustion engine inertia, and be attended by vibration, shake etc.This problem was difficult to solve especially when the rotating speed of bent axle surpassed the resonance region of drive system when internal-combustion engine inertia moves, because play a part strong especially in this acceleration of in work tempo, (not having burning, only that is to say to expand) bent axle.Particularly this unrestful operation people owing to the reason internal-combustion engine of travelling comfort are undesirable.
Therefore people hope to improve the characteristic of inertia run duration internal-combustion engine, particularly overcome described defective.
Summary of the invention
Advise a kind of being used for of independent claims characteristic of having at operation method and a kind of power supply unit of automobile by oil-engine driven motor according to the present invention.Some favourable schemes are themes of dependent claims and following explanation.
Advantage of the present invention
The present invention has overcome described defective, its way be by petrol-electric generating set (being called lighting generator (Lichtmaschine) usually) at the inertia run duration targetedly in the output terminal short circuit.Generator even when the slow-speed of revolution is particularly also below idle rotating speed, when stopping, as long as at least two phase short circuits just can obtain considerable moment from the bent axle rotation.It can overcome the bent axle acceleration through this measure, and consequently the operation of the inertia of motor was both also quiet more more fast.
The short circuit of in a kind of preferred scheme, accomplishing generator according to the rotating speed and/or the position of bent axle.
When generator can reach short especially engine inertia operation during in the following short circuit of rotating speed upper threshold value.The moment that the generator aspect improves receives as additional drag torque and equally affacts on the bent axle, and stopping through this measure occurs ahead of time.Shortened the inertia operation of internal-combustion engine widely through the active influence of generator.
When make generator short circuit then can reach engine inertia operation tranquil especially in the across-the-line starting system according to crank angle.Wherein be preferably the short circuit that one or more certain crankshaft angle interval activates the generator phase, undesirable acceleration that causes through the compressed-air actuated expansion in the cylinder takes place in described crankshaft angle interval.The situation of generator short circuit particularly appears at least temporarily making during the working stroke of internal-combustion engine.In the inertia operation phase, air throttle is stayed open now, so just can blow down the residual gas of cylinder.Could make favourable initial conditions for back to back across-the-line starting like this.(after corresponding upper dead center) is because the moment that the higher periodic bent axle acceleration of the load in the cylinder (being felt as the vibration of raising) improves aspect generator obtains balance when expanding.
Before the phase short circuit, in the generator at electric excitation field current is risen to maximum value suitably.In the field current of PWM-control, pass to permanent electric current basically then.Yet, change field current in order to produce desirable braking moment through generator, perhaps the regulation field current also is suitable targetedly.
The present invention advantageously can be used in more such generators, and promptly their output voltage carries out rectification through the rectifier with the conversion element that can trigger.A kind of like this rectifier can be used as synchronous rectifier, heighten regulator (Hochsetzsteller), turn down regulator (Tielsetzsteller), the operations such as (Pulswechselrichter) of pulse inverter.Make wherein at least two phase short circuits through corresponding triggering then to conversion element.The present invention can realize especially simply at this, even can in existing systems, realize.Even in having the generator of diode rectifier through less conversion element is set, IGBT for example, perhaps MOSFET just can realize the present invention.
Power supply unit according to the present invention has motor and the computing unit that has the switch gear that is used for the motor output end short circuit, and the controller of automobile for example, said computing unit particularly are designed to carry out according to the method for the invention on program technic.
Form with software realizes that the present invention also is favourable, because it is few especially to do the cost that is produced like this, particularly also is used for other task when the controller of carrying out, and therefore is provided with anyway.The suitable data carrier that is used to provide computer program is floppy disk, hard disk, flash memory, EEP-ROM, CD-ROM, DVD etc. particularly.Also can pass through computer network (Internet, Intranet etc.) downloads.
Can obtain other advantage of the present invention and scheme from specification and accompanying drawing.
Certainly, foregoing and back also not only can be used the characteristic of explanation in the corresponding combination of having explained, and also can use in the combination at other under the situation that does not break away from framework of the present invention, perhaps uses separately.
By the embodiment's sketch in the accompanying drawing the present invention is shown below, and the present invention is carried out detailed explanation with reference to accompanying drawing.
Description of drawings

Fig. 2: sketch illustrate according to power supply unit of the present invention by oil-engine driven second form of implementation.
The practical implementation form
Identical parts are represented no longer repeat specification for brevity with identical reference character in Fig. 1 and Fig. 2.
Circuit diagram according to first preferred implementing form of power supply unit of the present invention has been shown in Fig. 1, and has totally represented with reference character 100.Power supply unit 100 has motor 10 and rectifier means 20.Rectifier means when the machine generator operation usually as rectifier operation, when motor moves as invertor operation.Said motor 10 is driven by the bent axle 2 of internal-combustion engine 1.
10 sketch ground of generator component illustrate with the staor winding 11 of y connection and the excitation parallelly connected with diode or the form of rotor winding 12.The rotor winding is through the conversion of circuit breaker 13 beat ground, and said circuit breaker is connected with the joint 24 of rectifier means 20.Triggering to circuit breaker 13 is to be undertaken by the degree of field regulator 15, wherein, circuit breaker 13 also with the same intergrated circuit (ASIC) that normally is integrated in the application specific of field regulator with rotor winding 12 diode connected in parallel in.
What in the application's framework, illustrate is three phase generator.Yet say that in principle the present invention also can be used in the less or more heterogeneous generator, for example in the generator of five phases.
Rectifier means 20 is designed to the B6 circuit at this, and has switching element 21, and said switching element for example can be designed to MOSFET or IGBT, and switching element 21 for example is connected with the corresponding staor winding 11 of generator through conductor rail.In addition, switching element also is connected with joint 24,24 ', and when relative trigger, gives the onboard power system of automobile, comprises that storage battery 30 provides direct current.Through flip flop equipment 25, trigger through 26 pairs of switching elements 21 of trigger port, wherein, for the sake of clarity do not give all dated reference characters.Flip flop equipment 25 obtains the phase voltage of single staor winding respectively through phase passage 27.In order to provide these phase voltages that other device can be set, yet for the sake of clarity they are not illustrated.Flip flop equipment 25 is confirmed the rotating speed of internal-combustion engine through the phase passage.Flip flop equipment 25 can be the constituent element of motor controller.
Flip flop equipment 25 is analyzed the phase voltage that provides through phase passage 27 when (synchronously) rectification moves, and confirms that therefrom single MOSFET's 21 switches on and off time point accordingly.Control through trigger port 26 applies effect to grid (Gate-) joint of MOSFET 21.
Disclosed field regulator, the same with field regulator 15 set in the framework of this form of implementation, have so-called wiring terminal-V-joint 19, being connected of the staor winding of said joint and generator.Pairs of posts in controller 15-V-signal, perhaps the frequency of phase input signal is analyzed, and is used for the activation of conditioner operation according to the special parameter of this signal, perhaps deactivates, and triggers circuit breakers 13 through triggering circuit 14 at last.As shown, also can lead through the phase signals that 25 pairs of flip flop equipments are used for phase signals input 19.
Fig. 2 illustrates the circuit diagram according to second preferred implementing form of power supply unit of the present invention, and totally representes with reference character 200.This power supply unit 200 has motor 10 and rectifier means 220 again.Rectifier means 220 is designed to have the diode rectifier of rectifier diodes 221.
In order to make staor winding 11 short circuits, power supply unit 200 has the switch gear of having 301, for example IGBT, the perhaps circuit 300 of MOSFET.Switch gear is for example preferably triggered by motor controller by flip flop equipment 25.
With reference to figure 1 and Fig. 2 a preferred form of implementation is according to the method for the invention explained below.
When internal-combustion engine 1 should stop, at first interrupt defeated fuel, so consequently the rotating speed of internal-combustion engine descends.As long as flip flop equipment 25 recognizes, rotating speed drops to the rotary speed threshold value of regulation and just uses this method in the said form of implementation when following.Can guarantee that through monitoring rotation speed the short circuit of the output terminal of generator can not cause damage owing to electric current is too high.
If numerical value is set to a short as far as possible inertia operation phase, then the staor winding 11 of generator 10 is lasting short circuit through corresponding switch gear 21 or 301 later on being lower than the rotating speed threshold values basically, until internal-combustion engine reaches parking.
When on the contrary-for example in the across-the-line starting system-numerical value is set to tranquil as far as possible motor inertia is in service then to be lower than behind the rotating speed threshold values short circuit that realizes staor winding 11 according to the angle of bent axle 2.That is to say that this shows, unpeaceful inertia operation mainly is owing to the expansile injection to cylinder in working stroke causes that bent axle quickens to cause.Suitably through the additional moment of short circuit generation of generator during working stroke, quicken for this reason in order that prevent bent axle by this way.
