Abstract
The invention relates to a speed ratio control method of a stepless speeder. The method stabilizes a rotating speed of a motor at a speed corresponding to a gasoline throttle pedal through the automatic control of an electrical gasoline throttle, and then regulates the speed ratio of the stepless speeder to optimize the working condition of an internal-combustion engine. The control method changes the disadvantage that the traditional stepless speeder and the motor can not function with each other, and fully develops the potential of the internal-combustion engine, greatly cuts down oil consumption, and decreases waste gas discharge. The invention can also ensure that the acceleration of vehicles be manually regulated by drivers freely at any time, thus enhancing the driving interest, changing the design concept that automobile manufacturers always seek for increasing the power of the internal-combustion engine to enhance the acceleration.
Description
Technical field
The present invention relates to a kind of controlling method of stepless speed variator, relate to a kind of speed ratio control method of stepless speed variator of vehicle specifically.
Technical background
As everyone knows, the speed ratio control method of traditional stepless speed variator is mainly continued to use the controlling method of automatic transmission, and its Transmission Ratio Control is to change according to Control Parameter selected in the automobile running to determine whether the needs gear shift.At present mainly adopt the control of two parameters, i.e. the speed ratio that determines whether changing stepless speed variator according to the engine throttle opening and the speed of a motor vehicle of vehicle running state.At " automotive electronic technology " of Wu Jian and Shi Wenku chief editor's " Hyundai Motor new technology " detailed statement is arranged all.
Mainly can only lean on the parameter of being gathered to come the Passive Control speed ratio to change when the shortcoming of tradition stepless speed variator speed ratio control method is vehicle operating, can't make internal-combustion engine be in optimum Working.
Summary of the invention
The problems referred to above that the present invention is directed to the prior art existence provide a kind of controlling method of stepless speed variator of vehicle speed ratio, its technical problem that will solve is: the controlling method of improving traditional stepless speed variator, stepless speed variator is controlled mutually with internal-combustion engine mutual, acting in conjunction makes the internal-combustion engine overwhelming majority time be in optimum Working.
Above-mentioned technical problem of the present invention can realize by following method: the throttle on the internal-combustion engine is designed to E-Gas, the a certain specific rotation speeds of the corresponding internal-combustion engine of each angle of gas pedal is stabilized in engine speed on the pairing rotating speed of gas pedal by the automatic control of E-Gas.Regulating by the speed ratio of stepless speed variator makes internal-combustion engine be in optimum Working again.The speed ratio variance ratio of stepless speed variator is by the difference decision of indicated rotating speed of target of gas pedal and internal-combustion engine actual speed.Relation between them fixedly installs, and also can artificially change at any time.
Stepless speed variator speed ratio control method of the present invention is compared following advantage with traditional stepless speed variator speed ratio control method: stepless speed variator speed ratio control method of the present invention has changed the shortcoming that traditional stepless speed variator can only passive speed change, realized and the internal-combustion engine interaction, the internal-combustion engine energy is brought into play to greatest extent, reduced oil consumption, reduced discharging, the speed ratio variance ratio of stepless speed variator in the time of easily realizing manually changing the vehicle acceleration and deceleration has at any time been avoided strengthening combustion engine powered design method for pursuing acceleration.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the invention is described in further detail:
Accompanying drawing: stepless speed variator controlling method sketch
Embodiment
Accompanying drawing shows a kind of preferred stepless speed variator controlling method sketch, the rotating speed of target of the aperture decision internal-combustion engine of gas pedal, the actual speed of E-Gas controlling combustion engine, the speed ratio of the aperture signal deciding stepless speed variator of E-Gas.The best accelerator open degree of internal-combustion engine that running parameter decision stepless speed variators self such as the water temperature oil temperature of internal-combustion engine set.The speed ratio variance ratio of the difference decision stepless speed variator of the internal-combustion engine rotating speed of target that gas pedal is indicated and the actual speed of internal-combustion engine.
When vehicle brings into operation, controlled by the indicated internal-combustion engine rotating speed of target of gas pedal, E-Gas is regulated self aperture, and the internal-combustion engine actual speed is drawn close to rotating speed of target.Simultaneously, stepless speed variator receives that gas pedal breaks away from the signal of idling mode, and self speed ratio is constantly regulated in beginning, pins down the aperture of E-Gas, makes it to be in all the time best aperture state up and down in the certain limit.
When vehicle need quicken, internal-combustion engine rotating speed of target and internal-combustion engine actual speed that gas pedal is indicated are inconsistent, E-Gas continues to increase aperture continues to increase the internal-combustion engine actual speed, when perhaps external load strengthens, continue to increase in order to adapt to load variations E-Gas aperture, as long as the E-Gas aperture arrives one when delimiting, the speed ratio of stepless speed variator constantly increases under these situations, the difference of rotating speed of target and actual speed is big more, and the speed ratio variance ratio of stepless speed variator is big more.
Equally, when the E-Gas aperture is reduced, when the E-Gas aperture needed only less than a certain scope of best aperture, the speed ratio of stepless speed variator just constantly reduced, and the speed ratio variance ratio is also decided with the difference of rotating speed of target and actual speed.In case when stepless speed variator was received the idle signal of gas pedal, stepless speed variator was made reflection immediately, make the speed ratio of stepless speed variator reach maximum with the fastest speed ratio variance ratio, get ready for regulate next time.
In the actual design, stepless speed variator speed ratio variance ratio and internal-combustion engine rotating speed of target and actual speed difference corresponding relation will be considered the power surplus between maximum throttle aperture and the best accelerator open degree, take into account acceleration and travelling comfort, also can adapt to different drivers' hobby by the artificial step-less adjustment of driver.
