Description

String data interlock interlocking has the rack-and-gear spring assembly accumulator of dimension resistance ejectable

Affiliated technical field:

The present invention relates to a kind of accumulator, especially can hold power and vehicle is discharged the accumulator that collected devote every effort to help power raises speed through car retardation being collected kinetic energy.

Technical background:

According to the fuel consumption data that Ministry of Industry and Information regularly announces in " Chinese automobile fuel discharge website ", be example with 1.5L 1.6L manned vehicle, most vehicles go in the urban district than go in suburbs more increases by 50%---70% oil consumption.Brake deceleration is the one of the main reasons of consumption increase with starting speed-raising continually.Because China's automobile and battery-driven car recoverable amount are big, annual for this reason energy that consume very surprising with the pollutions that increase more more.

Improving the problems referred to above can be with installing the method for holding the devote every effort to help power apparatus additional, promptly with accumulator as the brake companion, to car retardation and collect kinetic energy and hold power, discharge power-assisted during speed-raising again, thereby reduce the loss of the energy and parts.But present known vehicle accumulator is adopted by actual because of each defectiveness is difficult.Mainly there is following problem: 1, it is little to hold the power capacity.2, it is short to hold force-stroke.3, the antagonistic force fluctuation to vehicle when holding power is big.4, accumulator holds and withdraws from the power of holding suddenly after full, causes the instantaneous mechanical resistance power of holding that loses of vehicle, to making vehicle security flaw occur, and 5, structure and profile are not easy to mounting arrangements on car load.6; 26S Proteasome Structure and Function is simple and single, can not satisfy the actual requirement of vehicle ', for example: when spring is in when holding the force deformation state near maximum; It is very big to hold mechanical resistance power; If start the power of holding this moment, the bigger mechanical resistance power of holding that moment produces can cause vehicle ' not steady, this situation takes place in rain main road cunning is run at high speed will cause security flaw; And for example: the acceleration of vehicle is selected to quicken slowly to quicken with fast according to road conditions in reality, but at present the known vehicles accumulator to hold power be ccasual with the size of releasing power, fail controlled, so also be prone to the generation deleterious effect.

In sum, hold power and power-assisted the brake and the acceleration of vehicle exerted an influence, both can produce wholesome effect; Also can produce injurious effects, and the brake system of vehicle and accelerator device has safety, reliability; Stability, multinomial composite request such as controllability, and by its perfect mechanism's rice assurance; Its structure and remarkable uses accumulator to hold power as car retardation and the power-assisted acceleration can not be oversimplified.So accumulator can only come design and use as the brake companion; And can not produce deleterious effect to brake system; More can not substitute brake fully and using, comprehensively correlative factor in the vehicle ' and requirement are included mentality of designing in and are come the perfect frame setting, just can meet application request.

Summary of the invention:

The present invention is a kind of accumulator; It is a kind of accumulator that uses as the brake companion; This accumulator is the rack-and-gear spring assembly accumulator that string data interlock interlocking has dimension resistance ejectable, dispose perfect control system and keep resistance mechanism with holding after full, and it is little to hold the mechanical resistance fluctuation; And be provided with to vehicle and quicken slowly, quicken soon and the slow release power of the demand of making a spurt, partly launch and release power soon and launch three kinds entirely and release the power mode, can satisfy the system requirements of vehicle.

Because rack-and-gear has 87%---94% higher driving efficiency; The power of the holding ability of draw, the pressing spring friction stress being out of shape is far above the power of the holding ability of clockwork spring wind spring bending stress distortion; So by tooth bar with draw, pressing spring forms tooth bar spring assembly conduct and holds the power unit; Adopt the rack-and-gear transmission; Hold the power unit by many groups and be together in series as the force mechanisms that holds of accumulator by group interlock mode, and with the having to the support beam assembly of the short cylindrical trough of belt needle roller track of tooth bar walking as the basis of its installation with support of frame-type, hold the power case thereby constitute the string data interlock rack-and-gear spring assembly of interlocking with interlocking through order.For improving intensity, whole gears and the axle making that drives its rotation are become one, promptly be made into the gear wheel shaft of a rooted tooth axle one.Because gear can drive the tooth bar of two parallel opposed longer sides up and down at most simultaneously, thus a rooted tooth wheel shaft can dispose at most about two-layer parallel opposed longer sides with the corresponding tooth bar spring assembly of its gear quantity.The tooth bar spring assembly as holding the power unit, being adopted the rack-and-gear transmission, hold the power unit by many groups and be together in series as the force mechanisms that holds of accumulator by the mode of group interlock with interlocking through order, is one of core of the present invention, also is initiative.The method can increase and decrease flexibly holds the power unit, makes little, the stroke of capacity of puzzlement accumulator short, the big problem of fluctuation is able to solve.

Support beam be shaped as the oblong thin slice, have centre hole so that gear wheel shaft passes at the thin slice center.Centre hole is respectively installed two row's short cylindrical trough of belt needle rollers conducts walking passage of two layer racks up and down up and down.Support beam is by the equidistant arrangement that is slightly larger than the tooth bar width, and fastening with screw rod and spacer, promptly constituted the framework that holds the power case---the support beam assembly.The continuity that need only keep gear wheel shaft, the arrangement of support beam can be striden separation according to the requirement in vehicle actual installation space, to adapt to flexible on vehicle, installing.

Order is last group by the tooth bar spring assembly of group interlock and interlocking and accomplishes when holding power the interlock back and hold a power for; After being linked, one group of back with last group of interlocking and its jump out of mesh is no longer produced hold mechanical resistance power, is controlled in all the time in the big or small scope of resistance that single group tooth bar spring assembly produced so hold the big minor swing of mechanical resistance power.Simultaneously, owing to can increase and decrease the quantity of tooth bar spring assembly according to actual needs neatly, also make accumulator have long force-stroke and the bigger power of the holding capacity of holding.In the end one group of tooth bar spring assembly is provided with at the back and keeps resistance mechanism after interlock is held completely, to solve the resistance problem of losing.The present invention at first proposes to lose the resistance problem and set up an organization in the design of accumulator to solve, and also is one of core of the present invention so hold full dimension resistance device.

Utilize the secondary unidirectional lock characteristic of ratchet that lock power ratchet device and normal lock gear wheel shaft are set, make it when not holding power, can oppositely not release the power rotation, gear wheel shaft has also pinned the tooth bar spring assembly thus, does not allow it to release power automatically.Behind release lock power ratchet device, the power of releasing has just begun.The process of releasing power is that the tooth bar spring assembly of having interlocked oppositely discharges by the group release, so guaranteed to have the long force-stroke of releasing.In order to obtain the bigger power of releasing, articulation mechanism is set, and controls articulation mechanism and before releasing power, remove interlocking in advance; Because lock power ratchet device has pinned gear wheel shaft; Gear wheel shaft bottles up tooth bar and discharges, still can not be released so be disengaged the tooth bar spring assembly of interlocking, but after will locking the release of power ratchet device; Each the tooth bar spring assembly that is disengaged interlocking will discharge simultaneously, promptly produce the power of releasing of ejection type.If before releasing power, only the part tooth bar is removed interlocking, as: 20 groups of tooth bar spring assembly, remove one group of interlocking for 3 groups at interval; Promptly obtain 5 groups and do not interlocked, when discharging, 5 groups will discharge simultaneously; And 5 groups of release releases thereupon thereafter when it has discharged; Promptly 20 components 4 times discharge, and 5 times of having been increased of the power of releasing are released force-stroke and are shortened to 1/5th.Release the power method and be respectively slow release power for above-mentioned 3 kinds, launch the power of releasing entirely and partly launch and release power soon, can solve accumulator respectively is that vehicle quickens slowly, and spurt and the fast power-assisted problem of quickening also make simultaneously and release the big or small controlled of power and be ccasual no longer.The present invention proposes accumulator release power must controlled notion, and designed articulation mechanism, so to release the power mode be one of core of the present invention too for the articulation mechanism of this accumulator and controlled three kinds.

Installation and the layout of accumulator on vehicle: because the power of the holding case profile of accumulator is thin cuboid; For cart; Can be installed on the level attitude of vehicle seat and schoolbag frame; And can decorate and dispose and replace vehicle seat and schoolbag frame function, its power taking to release the power input-output system can being placed in the triangle free area below vehicle seat and the schoolbag frame holding plane on the power case.For the above vehicle of three-wheel, accumulator can be arranged in the free area on the chassis, and on the chassis, as long as guarantee the continuous whole of gear wheel shaft, rack-and-gear spring assembly and support thereof can adapt to the chassis real space and stride discharging at interval.

The technical scheme that the present invention adopted is following: this accumulator by 3 systems totally 10 parts form: 1; The power system of holding is totally 4 parts: lock power ratchet device; Release power side locating plate, string data interlock interlocking has the rack-and-gear spring assembly of dimension resistance ejectable to hold the power case, power taking side locating plate.2, power input-output system totally 3 parts are released in power taking: power taking belt wheel set, release the powershift gear pair, main shaft band main pulley and ratchet assembly.3, control system is totally 3 parts: release the power thread drawing mechanism, launch thread drawing mechanism, the power taking thread drawing mechanism.

In holding the power system; The structure of holding the power case with form as previously mentioned; The support beam of equidistantly arranging two layer rack spring assembly up and down is supported in the track of its short cylindrical trough of belt needle roller composition; Adopt the rack-and-gear transmission,, interlock and interlocking elements are installed on support beam and hold Man Houwei resistance mechanism corresponding to the tooth bar spring assembly.Holding power case both sides, power taking side locating plate is being installed respectively and is released power side locating plate.Between two layer racks, two ends were fixed on power taking side locating plate and release on the power side locating plate with flange by bearing or pearl retaining structure respectively about gear wheel shaft was installed in.Lock power ratchet device is installed in to be released on the power side locating plate, and the restriction gear wheel shaft can only rotate by holding force direction during lock power, and is in normal lock state.

For make the first tooth bar in upper strata (50-1) can before go out and gear wheel shaft (5) engagement; Afterbody can lean against again on its co-acting lever, adopt tooth bar (50) thus under the motionless situation of tooth minister degree, hold the microcephaly and elongate a corresponding size and be made as the first tooth bar (50-1) in upper strata.In Fig. 9; Interlock system is installed on the support beam, leans on to such an extent that too closely interfere between them when preventing to install, and is arranged apart before and after adjacent interlock system is divided; Promptly being divided into two row installs at interval; Like interlocking depression bar assembly (55) among Fig. 9 is the row near gear wheel shaft, and band joint interlocking depression bar assembly (63) and band joint are changed layer interlocking depression bar assembly (59) and be another row far away, for guaranteeing the conformability of tooth bar interlocking on stroke; In Fig. 9 and Figure 10, will the pairing tooth bar of a contigency locking device far away partly extend corresponding size and be made as long tooth bar (50-2) at following front end major part of tooth minister degree unmodified situation.First toothed rack of lower floor is the first tooth bar (57) of lower floor, changes layer because of relating to, and it is that tooth bar (50) has been opened individual groove in the side and processed.In sum, the first tooth bar (50-1) in upper strata is special-purpose tooth bar with the first tooth bar of lower floor (57), and all the other tooth bars dispose tooth bar (50) and long tooth bar (50-2) respectively by the distance of itself and cooresponding interlock system.Because the tooth minister degree of all tooth bars is constant, so guaranteed the unanimity of transmission process stroke.The difference of four kinds of tooth bars is referring to Figure 10 and description of drawings thereof.It is following to hold the power process: after power taking is held power and begun; Gear wheel shaft (5) clickwise; Driving the first tooth bar in upper strata (50-1) pulling holds power extension spring (51) and moves forward into and hold force-stroke; When it will be covered when holding force-stroke; Just pushing interlock drag-line (49) rotate forward through pulling co-acting lever (53) and drives interlock depression bar (54) pushing second toothed rack (50) and get into gear wheel shaft (5) engagement and hold force-stroke, and second toothed rack (50) gets into to hold and promotes and depress interlocking depression bar assembly (55) after the force-stroke again and drive that interlocking gear (56) pushes away upper strata head tooth bar (50-1) and the engagement and the locking of gear wheel shaft (5).The interlock interlocking of its subsequent action and follow-up tooth bar according to said method repeats.Change layer because of relating to during upper strata end tooth bar (50) the interlock first tooth bar of lower floor (57), the first tooth bar of lower floor (57) is promoted to mesh entering with gear wheel shaft (5) hold force-stroke so its interlock is changed layer interlock depression bar assembly (58) by tooth bar (50) front end through pushing.The first tooth bar of lower floor (57) changes layer end, interlocking depression bar assembly (a 59) locking upper strata tooth bar (50) with the end face pushing band joint of its side groove again after getting into and holding force-stroke.The last tooth bar (50) of lower floor links at last and holds full dimension resistance co-acting lever assembly (60), makes its pulling dimension resistance backguy (61) tighten up friction lining (62), the friction wheel of friction lining (62) and main pulley coenosarc is produced and holds the close friction drag of mechanical resistance power size.So far, holding power accomplishes.The action that friction lining (62) is kept resistance only just can stop after decontroling the power taking backguy, and its principle of work is referring to Figure 16 and description of drawings thereof.In Fig. 9, the power of releasing is reversed with the power of holding.The process of releasing force-stroke is following: after gear wheel shaft (5) was unlocked, the tooth bar spring assembly of accomplishing the power of holding at last at first discharged, when it will discharge with regard to the interlocking of release to a last toothed rack; One group of tooth bar spring assembly is discharged; So repeat, discharged until whole tooth bar spring assembly, the power of releasing is promptly accomplished.Because the effect of lock power ratchet device, hold power and release that power can be stopped in any position and restarted.The band joint interlocking depression bar assembly (63) that has disposed articulation mechanism is except the function of interlocking depression bar assembly (55); Can also before releasing power, make it remove interlocking, let the tooth bar spring assembly of being interlocked originally be in the state of waiting for that lock power ratchet device release gear wheel shaft (5) back just can discharge tooth bar through the total joint push and block rod assembly of pulling (64).The effect of lock power ratchet device is the unidirectional normal lock to gear wheel shaft (5), and interlocking then is the interlocking that occurs between tooth bar, so after interlocking is disengaged; When tooth bar walks to when gear wheel shaft (5) engagement place, still blocked and can not discharge by gear wheel shaft (5), interlocking is disengaged the instantaneous power of releasing that the hour rack spring assembly produces and passes to lock power ratchet by gear wheel shaft (5) and bear; Can not produce and impact system; And behind lock power ratchet device also release, the tooth bar spring assembly that is disengaged interlocking will discharge simultaneously, and formation is launched.The two contigency locking devices that the power case is held in this case have only disposed articulation mechanism to row wherein, so for partly launching configuration, when whole configuration, then possess and launch function entirely.Articulation mechanism and the principle and the working process that launch function are referring to Figure 13, Figure 14, Figure 15 and description of drawings thereof.

In Figure 10, the first tooth bar in upper strata (50-1) is to keep tooth minister degree constant on the basis of the tooth bar (50) in tooth bar extension spring group (52), holds size of lengthening to form the microcephaly.Long tooth bar (50-2) is on the basis of tooth bar (50), to keep tooth minister degree constant, stub end is stretched out a size form.The first tooth bar of lower floor (57) is on the basis of tooth bar (50), to open a groove in cooresponding side to form.

In Figure 11, co-acting lever (53) and interlock depression bar (54) be for to be connected with axle key, formation co-acting lever assembly.Regulating spring (65), regulating spring seat (66), spring perch backing pin (67) constitute asynchronous adjusting spring assembly.When interlock drag-line (49) is driven by last toothed rack (50); Drive co-acting lever (53); Interlock depression bar (54) promptly is driven to rotate; Pushing back one toothed rack (50) moves ahead and the gear wheel shaft engagement, and back one toothed rack (50) if can not be synchronous with last toothed rack, will produce interference when meshing with gear wheel shaft.When interfere taking place, regulating spring (65) is compressed, and back one toothed rack (50) is promptly paused and wait together moves ahead after synchronous with last toothed rack (50) again and gear wheel shaft meshes.

In Figure 12, interlocking depression bar assembly is made up of interlocking depression bar (68), interlocking gear torsion spring (69), interlocking gear (56), gear backing pin (70), interlocking pressure shaft (71).Tooth bar side clearance adjusting mechanism is made up of steel ball (73), tapering pin (74), trimming screw (75), and its principle of work is following: in the through hole that tooth bar (50) two ends are reserved, steel ball (73), tapering pin (74) are enclosed in the inside in case steel ball comes off by riveting.Trimming screw (75) thread head is a circular cone, and is corresponding with tapering pin (74), turns trimming screw (75) and promptly presses cooresponding two tapering pins (74) respectively to two side shiftings, and the gap that steel ball (73) is adjusted tooth bar (50) both sides is moved on the top.So actual in tooth bar (50) side is that steel ball (73) rolls on support beam.In Figure 12; The asynchronous adjustment shell fragment (72) of interlocking is following to the corrective action principle of interlocking between tooth bar (50): before back tooth bar (50) is chain during tooth bar (50); If preceding tooth bar (50) has been accomplished and has been held force-stroke; Then preceding tooth bar (50) can be held in its completion outside the position of force-stroke by the gear axle bumper, and back tooth bar this moment (50) the pushing interlocking depression bar (68) that moves ahead drives interlocking gear (56) and rotates preceding tooth bar (50) is pushed away gear wheel shaft and locking; But if preceding tooth bar (50) is accomplished when holding force-stroke as yet fully, back tooth bar (50) just moves ahead chain, when interlocking gear (56) rotates meeting because of with asynchronous the interfering of preceding tooth bar (50).For this reason, at tooth bar (50) front end installation interlocking asynchronous adjustment shell fragment (72) is set, when interfering, the asynchronous adjustment shell fragment (72) of interlocking is bent, and the rotation of interlocking gear (56) promptly pauses and waits for preceding tooth bar (50) and mesh and lock synchronously.

In Figure 13, the band joint interlock mechanism that is installed on the support beam (41) is made up of band joint interlocking depression bar assembly (63) and joint push and block rod assembly (76).Wherein: band joint interlocking depression bar assembly (63) includes joint assembly (77).

In Figure 15, the tooth bar that has side channel is as the first tooth bar (57) of the lower floor of special-purpose tooth bar, and this is the needs of interlock interlocking when changing layer.Change layer interlock depression bar assembly (58) by the front end pushing rotation of end, upper strata tooth bar; The first tooth bar of ejection lower floor (57) moves ahead and force-stroke is held in gear wheel shaft engagement entering; The first tooth bar of lower floor (57) gets into and holds after the force-stroke its side channel and promptly promote and depress the band joint and change a layer interlocking depression bar assembly (59), with end, upper strata tooth bar interlocking.In Figure 15, push and block rod assembly in joint is done to become a total joint push and block rod assembly (64) by combination system and is installed on the support beam (41), and has installed the control part additional, and this is for the ease of in accumulator, simultaneously a plurality of articulation mechanisms being controlled.It is constructed as follows: total joint push and block pull bar (90), joint push and block (81), launch adjustment nut in place (91), launch catch in place (92), launch interstage sleeve in place (93), launch pull back spring (94), pull bar return adjustment nut and packing ring (95).Its each part effect is following: when total joint push and block rod assembly (64) be drawn out put in place after, launch catch in place (92), launch interstage sleeve in place (93) and just limit it and no longer continued to pull out, with launching adjustment nut in place (91) adjustment position deviation.After loosening total joint push and block rod assembly (64), it i.e. return under the effect of launching pull back spring (94), and pull bar return adjustment nut and packing ring (95) are used for adjustment and confirm its return position.

In Figure 16, hold full dimension resistance device and hold full dimension resistance mechanism two parts and forms with cancelling by holding full dimension resistance mechanism, wherein, cancel and hold full dimension and hinder mechanism and form: four-bar mechanism (22), backguy hoop (96), swinging strut (23), Return spring (97) by following parts.Holding full dimension resistance mechanism is made up of following parts: friction disc support and pull back spring assembly (98), friction lining (62), dimension resistance backguy (61), interlock drag-line (49), hold full dimension resistance co-acting lever assembly (60), resistance is adjusted spring assembly (99).Principle of work and the process of holding full dimension resistance device are following: when power is held in power taking; Pulling power taking backguy (12) has spurred four-bar mechanism (22) and has rotated; Swinging strut (23) rotation is propped, be rotated the dimension resistance backguy (61) that support (23) props up and be limited in all the time in the backguy hoop (96).After the power case of holding completely; Interlock drag-line (49) is by lower floor's end tooth bar interlock; Pulling is held full dimension resistance co-acting lever assembly (60) drive dimension resistance backguy (61) and is tightened up friction lining (62); Make the friction wheel of itself and main pulley (31) coenosarc produce friction drag, its resistance size is adjusted spring assembly (99) adjustment by resistance.When decontroling power taking backguy (12); Swinging strut (23) is retracted by Return spring (97); Dimension resistance backguy (61) loses support to be loosened, and friction lining (62) is also loosened and under the effect that is installed in friction disc support and pull back spring assembly (98) on the support beam (41), resets, and the dimension resistance is promptly cancelled.

In Figure 17, the working process that launches thread drawing mechanism is following: backguy (100) is launched in pulling, launches swing arm (101) and rotates, and total joint push and block rod assembly (64) is extracted in jack-up pull bar backguy (102) out, and interlocking promptly is unlocked and is in treats ejection status.Backguy (100) is launched in relieving, launches swing arm (101) return, and total joint push and block rod assembly (64) is in that wait for after the power of releasing could return, and the power case of holding still keeps treating ejection status.Releasing the power thread drawing mechanism is installed in by its front frame (113) and after poppet (106) and releases on the power side locating plate (2).The working process of releasing the power thread drawing mechanism is following: power backguy (103) is released in pulling; Backguy (105) also drove release backguy (30) subsequently in the middle of backguy pin pulling claw (104) promptly spurred the power of releasing; Releasing in the middle of the power backguy (105) overcomes the pulling force of only releasing returning pull-spring (108) and will release power rotation trim ring (107) and draw rotation; Release and defeat the compressing that ring (112) is no longer released power rotation trim ring (107); Defeat ring stage clip (109) and it is pushed into forward to be pressed onto releases power ratchet (29) and make it and release power ratchet (28) position engaged and stop by releasing, its position of stopping is by pressure ring adjustable bolt (110) fine setting that puts in place.After this, release backguy (30) also is pulled to the position, holds the release of power case and discharges, and the power of promptly releasing begins, and main shaft is released powershift gear (111) clickwise and power is passed to released power ratchet (28) through releasing power ratchet (29).Unclamp and release power backguy (103); Only releasing returning pull-spring (108) will release power rotation trim ring (107) and retract; Release power rotation trim ring (107) and will release again and defeat ring (112) and push back, release power ratchet (29) and released power ratchet (28) and back down and reset, release backguy (30) is also retracted by the power of lock ratchet spring; Each part resets, and the power of releasing stops.The safety analysis of control system is following: 1, and in Figure 17, launch backguy (100) and release power backguy (103) if spurred simultaneously, launching; 2, in Figure 17, Fig. 2 and Fig. 3, if spurred power taking backguy (12) simultaneously and released power backguy (103); Since main pulley (31) pay through the power taking belt pulley power that passes to gear wheel shaft (5) when holding the power case and discharge single group tooth bar spring assembly to the power of gear wheel shaft (5); So after this be exactly to unclamp release power backguy (103) with holding power or dimension resistance this moment again, still can only continue the power of holding or dimension resistance; If what unclamp is not to release power backguy (103) but power is then released in power taking backguy (12); 3; In Figure 17, Fig. 2 and Fig. 3, if spurred power taking backguy (12) simultaneously and launched backguy (100), because the not release of lock power ratchet device (1); Multiple sets of teeth bar spring assembly is locked power ratchet (24) to the ejection force of gear wheel shaft (5) effect and is born and hold the power case and get into and treat ejection status; Because multiple sets of teeth bar spring assembly is paid the maximum, force that can transmit to the ejection force of gear wheel shaft (5) effect greater than the power taking belt pulley, can't rotate by driven gear axle (5) so the power taking belt pulley is paid simultaneously, the belt on it (20) will skid and main pulley (31) will be produced its maxim resistance; Do not rotate owing to gear wheel shaft this moment; Even if be in and hold full state and still can not start dimension resistance so hold the power case, this resistance of producing of skidding should be less than can making vehicle produce the minimum value of the dangerous resistance that breaks away when slippery when wet is run at high speed as previously mentioned, so be safe to vehicle; Unclamp and launch backguy (100), situation is constant, unclamps power taking backguy (12); Resistance promptly disappears, and spurs power taking backguy (12) again, and situation is recovered again; Promptly launch and hold the power case after backguy (100) is pulled and get into and to treat that ejection status is irreversible, the power case of holding must launch to have discharged just and can hold power again; This moment, it was exactly its power-assisted to vehicle that the ejection force that main pulley (31) receives deducts the resistance that receives if pulling is released power backguy (103) with launching.In sum, the operation of control system is to vehicle driving safety.
