Detailed description of the invention
The preferred embodiments of the present invention are described in detail below in conjunction with accompanying drawing.
In order to clearly set forth embodiments of the present invention, will avoid and the detailed description that belong to well known in the art other general electronic apparatus devices of main points of the present invention without direct correlation in this article.
Fig. 1 is the state variation schematic diagram of exemplary hybrid power system for automobile shift mode.As shown in Figure 1, hybrid power system can carry out normal mode in the drawings, switch between winter mode and other pattern according to the shift mode demand of chaufeur.Usually, orthodox car may have normally, winter, motion, manually, cruise, the multiple shift mode of economic dispatch.And for hybrid vehicle, also can the application examples shift mode such as dynamic as mixed in normal mixed dynamic, winter except above-mentioned pattern.Therefore, in this illustration, normal mode also comprises mixed mover pattern and immiscible mover pattern, and winter mode also will comprise mixed mover pattern and immiscible mover pattern.Compared with the shift mode of orthodox car, hybrid vehicle must consider the state of hybrid power system when selecting shift mode.Because whether mixed dynamic function can be used, the current torque capability of power system and efficiency etc. will be affected.Such as, when mixed dynamic function is unavailable, the shift mode of immiscible mover pattern can only be adopted.When mixed dynamic function is available, shift mode preferably will switch to mixed mover pattern from immiscible mover pattern.Therefore, for reaching the object optimizing power performance, driving and safety, the present invention according to the shift mode demand of chaufeur, and dynamically controls the switching of shift mode.
Fig. 2 is the schematic flow sheet of hybrid power system for automobile shift mode control method according to an embodiment of the invention.By embodiments of the invention, according to the shift mode demand of chaufeur, hybrid power system for automobile will select suitable shift mode.For selection and the switching of shift mode, the present invention considers following two kinds of conditions, and one is the shift mode request of chaufeur, and two is whether current mixed dynamic function can be used.
As shown in Figure 2, keep off mode control method to comprise:
In step sl, shift mode request is received;
In step s 2, judge whether the shift mode of asking comprises mixed mover pattern; Such as, for the example in Fig. 1, normal mode and winter mode all comprise mixed mover pattern, and other pattern does not comprise mixed mover pattern.
When asked shift mode does not comprise mixed mover pattern, in step s3, shift mode is switched to asked shift mode; Such as, for the example in Fig. 1, if what ask is other pattern, so hybrid power system will be directly switch into other pattern.
When asked shift mode comprises mixed mover pattern, in step s 4 which, judge that mixed mover pattern is current whether can use;
When mixed mover pattern current unavailable time, in step s 5, shift mode is switched to immiscible mover pattern;
When mixed mover pattern current available time, in step s 6, shift mode is switched gear to mixed mover pattern.
In another embodiment of the present invention, after performing step S5, current shift mode is immiscible mover pattern, and the method can also comprise:
In the step s 7, whether cycle criterion judges that mixed mover pattern is current and can use,
When mixed mover pattern current unavailable time, make current shift mode remain on immiscible mover pattern,
When mixed mover pattern current available time, perform step S6, current shift mode is switched to mixed mover pattern.
In above-mentioned step S4 and S7, can judge that mixed mover pattern is current according to the state parameter of hybrid power system for automobile and whether can use.
In one embodiment, described state parameter is high-tension battery magnitude of power, high-tension battery SOC value, motor available torque value.
Such as, can be each setting threshold of high-tension battery magnitude of power, high-tension battery SOC value, motor available torque value, when high-tension battery magnitude of power, high-tension battery SOC value, motor available torque value each be greater than respective threshold value time judge that mixed mover pattern is current available.
Again such as, it can be each setting threshold of high-tension battery magnitude of power, high-tension battery SOC value, motor available torque value, and carry out stagnant ring (being also referred to as back stagnant) to described threshold value, thus to avoid system status parameters to cause pattern continually to switch when Near Threshold fluctuates.For example, if arrange the single threshold value 17.5 of high-tension battery SOC, so when high-tension battery SOC value fluctuates about 17.5, the switching between mixed mover pattern and immiscible mover pattern will be there is continually.By carrying out stagnant ring to threshold value, only have after change to a certain degree occurs threshold value, judge mixed dynamic function can with or unavailable.Such as, for high-tension battery SOC value, when such as SOC value rises to 20 from 10, just think that mixed dynamic function can be used; And SOC is when being reduced to 15 from 30, just think that mixed dynamic function is unavailable.
Fig. 3 is the structural representation of hybrid power system for automobile shift mode control setup according to an embodiment of the invention.As shown in the figure, described control setup comprises receiving device, decision maker and shifter.Wherein, receiving device, is configured to receive shift mode request.Judgment means, is configured to judge whether the shift mode of asking comprises mixed mover pattern.Shifter, is configured to work as asked shift mode when not comprising mixed mover pattern, shift mode is switched to asked shift mode.Whether described judgment means is configured to further, when asked shift mode comprises mixed mover pattern, judge that mixed mover pattern is current and can use.Described shifter is configured to further, when mixed mover pattern current unavailable time, shift mode is switched to immiscible mover pattern.Described shifter is configured to further, when mixed mover pattern current available time, shift mode is switched gear to mixed mover pattern.
In another embodiment, whether described judgment means is configured to cycle criterion further and judges that mixed mover pattern is current and can use.Described shifter is configured to further, when mixed mover pattern current unavailable time, make current shift mode remain on immiscible mover pattern.Described shifter is configured to further, when mixed mover pattern current available time, current shift mode is switched to mixed mover pattern.
In one embodiment, according to the state parameter of hybrid power system for automobile, whether described judgment means judges that mixed mover pattern is current and can use.
In one embodiment, described state parameter is high-tension battery magnitude of power, high-tension battery SOC value, motor available torque value.
Such as, described judgment means is each setting threshold of high-tension battery magnitude of power, high-tension battery SOC value, motor available torque value, when high-tension battery magnitude of power, high-tension battery SOC value, motor available torque value each be greater than respective threshold value time described judgment means judge that mixed mover pattern is current available.
Again such as, described judgment means is each setting threshold of high-tension battery magnitude of power, high-tension battery SOC value, motor available torque value, and carry out stagnant ring to described threshold value, thus to avoid system status parameters to cause pattern continually to switch when Near Threshold fluctuates.
Exemplarily, Fig. 4 is the mutual schematic diagram of the signal of hybrid power system for automobile shift mode control setup in hybrid power system for automobile according to an embodiment of the invention.In this example, hybrid vehicle adopts Automatic Transmission, and has independently gearbox control.Communication is carried out by CAN network between gearbox control and entire car controller.Entire car controller and motor CAN network carry out communication.Gearbox control controls the switching of the shift mode of change speed gear box.Variable Rate is coupled to driving engine.
In this example, the multiple shift mode characteristic line that can demarcate can be stored in gearbox control, such as, the gear shifting characteristic deflection of mode of motion is radical, compared with common shift mode, such as the upshift speed of a motor vehicle is drawn high, and is not easy upshift and more easily stays in low gear, can provide better dynamic property., more easily there is upshift in winter mode for another example, dynamic property weakens, and propulsive effort reduces, and reduces the risk of skidding.The gear shifting characteristic of often kind of shift mode associates with the speed of a motor vehicle and accelerator pedal position.Such as, when the speed of a motor vehicle increases to over threshold value, upshift, when the speed of a motor vehicle reduces, downshift.Acceleration pedal is relevant to torque demand, and it is just large that acceleration pedal steps on darker torque demand.Under the identical speed of a motor vehicle, be transitioned into the easy upshift of little throttle from large throttle, and under high gear, if dark stepping on accelerator pedal, then downshift may occur because torque demand increases suddenly to force, meet operator demand to increase torque capability.
Again as shown in Figure 4, chaufeur can send instruction to gearbox control by entire car controller, specifies it to adopt which kind of shift mode.Gearbox control receives instruction and implements shift mode and switches, and performs gearshift according to selected shift mode.Be appreciated that according to the state parameter received, gearbox control also from entire car controller receiving system state parameter, and can judge whether mixed dynamic function can be used.
By the description of above embodiment, those skilled in the art can be well understood to the present invention and can realize by the mode of software combined with hardware platform, can certainly all be implemented by hardware.Those skilled in the art can understand, and when without departing from the spirit and scope of the present invention, can also do various change and replacement to the specific embodiment of the present invention.These change and replace and all drop in claims of the present invention limited range.
