Abstract

The present invention relates to a method of controlling vehicle speed and its single pedal device. The single pedal device is one combination of vehicle brake pedal and accelerating pedal. During the pedal is stepped down, throttle opening is first controlled and the brake valve is then started, that is, the pedal stroke includes two parts of deceleration stroke and braking stroke. The present invention features that only one pedal is stepped by the driver and this can concentrate his attention for repid reaction to emergency and running safety.

Description

A kind of method of control vehicle road speed and single pedal device thereof
Road speed control method of using on a kind of vehicle of technical field and the device of realizing this method.
Background technology is present, and acceleration pedal and brake pedal that vehicles such as the automobile of selling on the market are controlled its road speed are two pedals separating.Because two pedals separate, so will produce following unfavorable factor during steering vehicle:
1, the pin of chaufeur will move about between brake pedal and acceleration pedal, and labour intensity increases;
2, chaufeur wants a part of energy of polydispersion to note not misstep pedal when driving, and influences the high concentration of chaufeur attention, and it is in a rush to seem sometimes;
3, particularly chaufeur when vehicle ' runs into obstacle, the reaction time that vehicle needs in stopping distance is divided into nine periods, wherein two periods are: (1) chaufeur begins to do control action, the pin that is chaufeur begins to leave acceleration pedal, (2) chaufeur is finished control action, and promptly the pin of chaufeur is stepped on brake pedal, and one moves one steps on, increased the reaction time, unfavorable safety traffic.
4, chaufeur is being driven in case of emergency, because the ideological plane anxiety, and misstep pedal and cause the safety misadventure of car crash often to take place.
Summary of the invention the purpose of this invention is to provide a kind of method and device with pedal thereof of controlling road speed, accomplishes to alleviate chaufeur labour intensity, strengthens the attention of chaufeur, improves the safety performance of vehicle '.
Technical scheme is that the acceleration pedal of vehicle and brake pedal are merged into a pedal, control the throttle size in the pedal folding process earlier, the back starts braking valve, promptly original brake-pedal travel is divided into two partly: beginning partly is retarding travel, and the back just is a braking distance partly.
Compared with prior art, as long as characteristics of the present invention are when driving foot-operated pedal, and energy is concentrated, and reaction is fast when anything crops up, can guarantee traffic safety.

Fig. 2 is a single pedal device box cutaway drawing.
Fig. 3 is a single pedal device principle of work scheme drawing.
Fig. 4 is a single pedal device tread portion separation structure scheme drawing.
The specific embodiment such as Fig. 1, shown in Figure 2, control box 11 is fixed on the vehicle housing, treadle 4 one ends are pedal 1, the other end is connected on the axle sleeve of fulcrum 18 with sector 8, fulcrum 18 is fixed on the lower side panel of control box 11, sector 8 and miniature gears 10 engagements that are packed on the axle 20 of walking around, rotating shaft 20 is installed on the casing 24 of control box 11, be fixed with cam 22 and cam 26 in the rotating shaft 20, cylindrical cam 29 is radially fixed by key 19, axially can in rotating shaft 20, slide, be set with retracing spring 28 in it, on cylinder projection 29 cylinders positioning groove 25 is arranged, have an end to be fixed on locating dowel pin 9 on the casing 24 in the groove, ratchet-type recessed taken turns 23 and is sleeved in the rotating shaft 20, ratchet-type is recessed take turns 23 and casing 24 between extension spring 32 is housed, half locating dowel pin 30 is housed on casing 24 inner end surfaces.Have follower lever 14 to connect braking valve on the cam 22, cam 26 has follower lever 13 to connect throttle.Be equipped with on the casing 24 and make follower lever 14 and 13 abut against retracing spring 21 and 27 on cam 22 and 26 respectively.In order to control the position of treadle 4 well, present embodiment is fixed on mounted panel 12 on the vehicle, the registration mast 15 of restricted pedal 4 extreme positions and 16 and determine that treadle 4 is in driving engine to treat half locating dowel pin 6 of fast state on the mounted panel 12.Retracing spring 7 one ends are fixed on the treadle 4, and an end is fixed on the vehicle.
Introduce principle of work of the present invention in detail below in conjunction with Fig. 3:
1, when treadle 4 is in the b position, treadle 4 semidefinites is positioned at this by half locating dowel pin 6 on the mounted panel 12.The position that quadrant gear 8 is meshed with miniature gears 10 is in sector 8 center positions, and the follower lever 14 on the cam 22 is in extreme lower position, thereby braking is not worked.Follower lever 13 on the cam 26 also is in extreme lower position, so throttle place minimum position, driving engine is in the fast state for the treatment of.This moment, cylindrical cam 29 was under the effect of the locating dowel pin on the static housing 9, and its projection withdraws from recessed 23 the recess of taking turns of ratchet-type, take turns 23 and separate with recessed, and this moment recessed take turns 23 with casing on the just relative semidefinite of half locating dowel pin 30 position.Treat that speed, vehicle are in not braking mode so make driving engine be in.
2, when treadle 4 trends towards a position, be that people's instep is when upwards mentioning treadle 4, treadle 4 will skid off half locating dowel pin 6, driving rotating shaft 20 by quadrant gear 8 with miniature gears 10 simultaneously clockwise rotates, rotating shaft 20 drives cylindrical cam 29 again and rotates, under the effect of locating dowel pin 9, the projection of cylindrical cam slips into recessedly takes turns in 23 recesses and meshes, simultaneously half locating dowel pin 30 is also taken turns 23 and is skidded off from recessed, recessed take turns spring 32 beginning on 23 pulled down be recessed take turns 23, take turns 29 and make rotating shaft 20 continue to produce to clockwise rotate by cylinder is recessed, make the projection of cam 26 partly begin jack-up follower lever 13, follower lever 13 jack-up throttles quicken vehicle ', with it simultaneously, treadle 4 has a kind of toward the trend of a to perk, but has been controlled by the human pin.Like this, people's pin makes treadle 4 be in certain altitude, just can handle and control the size of throttle.Pin one is proposed acceleration, and pin one is stepped on deceleration.When treadle 4 reached a position, what follower lever 14 was positioned at cam 22 always waited circular arc partly, not by jack-up, therefore brake use, and follower lever 13 is positioned at cam 26 projection part highest points, and throttle is backed down maximum, and Vehicle Speed is the fastest.
3, make treadle 4 when the c locality moves when the human pin, be in minimum through b position throttle, driving engine is treated speed, and cylindrical cam 29 is taken turns 33 and separated with recessed, recessedly takes turns 23 under 30 effects of half locating dowel pin, place's semidefinite is positioned at this, spring 32 is inoperative, waits circular arc partly and follower lever 13 is positioned at cam 26, therefore until treadle 4 when arriving the c positions, throttle all is minimum, and driving engine is in treats speed.Simultaneously, cam 22 bossings of left-hand revolution begin jack-up follower lever 14 with it, and follower lever 14 pushes braking valve and begins braking.When treadle 4 arrived the c position, follower lever 14 was positioned at partly highest point of cam 22 projectioies, and the effect that follower lever 14 pushes braking valve reaches maximum, and vehicle braked has also just reached maximum.
For the pin that makes the people steps and control pedal 1 more exactly, present embodiment is provided with on pedal 1 ties up the pin annex.As shown in Figure 4, the card knot 3 and 31 of two band springs is housed on the pedal 1, on card knot 3 and 31, movably spur rack 5 and 33 is housed respectively, belt 2 is housed on tooth bar 5, belt clamps 17 is housed on tooth bar 33.The combined action of tooth bar and card knot, belt, belt clamps makes and ties up the pin annex and can be fit to anyone foot breadth and highly, makes the people feel comfortable, and dynamics is arranged again when upwards putting forward.
