Abstract

The invention provides a creative instantaneous working and idling intermittence motor vehicle drive theory in the modern vehicle technology. The instantaneous working and idling intermittence motor vehicle drive theory breaks through the blockage of a traditional mode; further energy saving and emission reduction are used as purposes, and the application and design philosophy of people first, essence inheriting, habit respecting, safety first, convenient control and the like is particularly emphasized. Inertial kinetic energy is directly used through an additionally-arranged clutch, a driving device of a vehicle is divided into a working driving state and an idling driving state, and the working driving state and the idling driving state are very ingeniously and organically combined. Through a simpler dynamic and static combination driving mode, consumed energy and practical demands are matched with each other, and the consumed energy and practical energy consumption efficiency are balanced with each other. Under the common precondition of urban traffic roads and ideal vehicle speeds, through the 3397 kilometers of real vehicle simulation test, the accumulative working and idling distance rate is less than 26%, namely the vehicle travels 100 kilometers by the fuel of 26 kilometers of acceleration driving. A new shortcut is developed for energy saving and emission reduction of motor vehicles.

Description

Instant labour spare time discontinuous way motor vehicle drive theory and embodiment thereof

One. technical field

For self-propelled vehicle energy-saving and emission-reduction further again, we the vehicle in driving process as a moving whole, utilize the knowledge such as inertia, momentum, momentum and through comparatively systematic research and real vehicle analogue test, special proposition " Instant labour spare time discontinuous way motor vehicle drive theory " new ideas, break through the constraint in conventional drive mode at one stroke, walk out an Innovation

If this theory can be promoted and the practice of paying, estimate that self-propelled vehicle will on existing basis, the energy of (50%) about can not only saving half again, but also will at minimizing exhaust emissions, reduce running temperature, improve air environment, improve automatic control level, improvement brake efficiency, extend all many-sides such as actuating device service life, produce how better direct benefit.

Two. background technology:

1, current self-propelled vehicle is in its through running process, and its actuating device is always in a kind of state of whole process unlatching.As: the driving engine of automobile, from startup, idling, starting, traveling, acceleration until just can engine running be stopped at the end of whole stroke.

2, existing vehicle drive unit (refering in particular to quartastroke engine) is owing to self structure just also existing great traction braking resistance, cause energy loss, that is: on physical construction, have too much internal consumption just to determine energy utilization rate extremely low (generally about 20%).

Three. summary of the invention

1, the proposition of this theory

Come out from self-propelled vehicle, just have one " momentum " although be easy to by people cognitive, also do not cause being absorbed in of common people, always out in the cold, also just let alone employ.Here it is " quality of self-propelled vehicle and speed determine jointly in the process of moving; moment just can with self-propelled vehicle dynamic mutually and give birth to, walk mutually and have, capable mutually and deposit a kind of in the same way, ' momentum ' of synchronized, equivalent, equivalent namely: it equals the product of sole mass and speed; physically claim it to be momentum " here, we are then its inertia kinetic energy (being produced a kind of energy of decision by force of inertia).

For inquiring into the inner link that inertia kinetic energy and energy-saving and emission-reduction and effect balance, we guaranteeing vehicle safety, people-oriented, respect custom, manipulate the design concept such as easy before under topic, with the corresponding conversion increasing control switch and maintain the former design of vehicle and Instant labour spare time discontinuous way type of drive, solving after driving engine is shut down with increase vacuum reservoir, check valve pipeline to use vacuum servo to carry out the effective brake of vehicle continuously, the automatic start-stop of driving engine is controlled by Das Gaspedal, with being installed in addition with corresponding software, hardware and facility (speed sensor, computing machine, circuit), accomplish to be a unit of time each second, obtain throttle simultaneously, the random switching signal of brake pedal and instantaneous velocity also define one group of group original data ... lucky America and Japan wagon (quadruple cylinder engine) is utilized successfully to carry out real vehicle analogue test, carry out pictorialization unified for main manifestations means to original data with notebook in car on the one hand to process, the collection of real-time dynamic data, record, the functions such as analysis integrate body, have employed again the mode of artificial manipulation on the other hand, carry out the random dislodging of hand gear gear box, be used for simulating the motoring condition that the overall energy storage of instantaneous active vehicle in this theory and instantaneous passive vehicular inertia kinetic energy discharge in order respectively, and by these two kinds of different objects, multi-form actual vehicle driving process, show this vehicle in (the objective permission of the desirable speed of a motor vehicle of maintenance, maximum speed under subjective desire) under prerequisite in scope, use distribution according to need, the energy resource consumption thinking supplied according to quantity ... its conclusion (of pressure testing) is: " the not busy distance of the work in accumulative 3397 kilometers of strokes is than 25.11%, average ground speed is 35.23 kilometers/per hour, the multinomial gratifying datas such as the Actual Burnoff amount of accumulative 5294 kilometers is 4,26 liters/100 kilometers, is 6.5 liters/more than 100 kilometers originally, its fuel-economizing ratio nearly 35%." " note: current real vehicle analogue test has only accomplished the not busy interval of work in the process of moving (the not busy interval of dynamic work); do not realize the not busy interval of omnidistance work (the not busy interval of work of dynamic and static full state), driving engine and driving system also do not carry out any optimization process in addition.As: still have employed idling when the red lights such as crossing, traffic congestion, the inreal repertoire embodying not busy power-transfer clutch of going to work.(these data are not best) "

2. the plain statement of pair this theory

" work " of this theory refers to that actuating device is in mode of operation---the work motoring condition of the desirable speed of a motor vehicle is reached rapidly by consuming the energy; " spare time " refers to that actuating device enters leisure (quitting work) state---by newly-increased work not busy power-transfer clutch (with minimum mechanical friction, the shortest mechanical drive train), inertia kinetic energy is discharged in order to the leisure motoring condition of (to remain in desirable vehicle speed range); " instantaneous " then refers to a period of time scope of even up to a hundred seconds from several seconds to tens seconds, the determination of its concrete length, then according to the actual demand in desirable vehicle speed range, carry out Based Intelligent Control by " artificially " or system " automatically " two kinds of modes.In other words, all conditions premised on the desirable speed of a motor vehicle, on the one hand carry out active work done energy storage by energy resource consumption and make that vehicle is instantaneous reaches the desirable speed of a motor vehicle, on the other hand meet by the not busy power-transfer clutch of work the mode that inertia kinetic energy adopts passive type to discharge in order, maintain the traveling in desirable vehicle speed range, what naturally form " a storage one puts " of vehicle or claim " a main quilt " repeats alternately, and the vehicle of continuous renewal travels new ideas, has also just described out the core of this theory and essence.

According to the not busy operating range of work in analogue test than the conclusion also less than 26%, also just describe, this theory has only used the fuel given it the gun less than 26 kilometers, under the prerequisite guaranteeing the desirable speed of a motor vehicle, has travelled the distance of 100 kilometers

3, the simple and easy viewpoint of this theory

(1) fully demonstrating with chaufeur is control theory originally

Das Gaspedal is the core component that this theory artificially manipulates.When chaufeur depresses Das Gaspedal, this theory performs the manipulative procedure of " work ": " first start the engine, again synchronously in conjunction with the not busy power-transfer clutch of work, guarantee that vehicle enters the motoring condition of active overall energy storage in time, make it to reach rapidly the desirable speed of a motor vehicle " after, at once unclamp Das Gaspedal and naturally reset, this theory performs again the manipulative procedure in " spare time " at once: " first make the automatic stall of driving engine, the motoring condition that not busy power-transfer clutch quick separating (to obtain minimum mechanical friction) of work allows inertia kinetic energy obtain passive type to discharge in order ", self-assembling formation " the not busy interval of work, mainly to be replaced " vehicle travel new paragon.

For alleviating the labour intensity of chaufeur, improving vehicle automatic control level, by " cruise " theory, being introduced in this theory.Arrange and adjective startup with full-time " operating knob " or " lever " initial value as " cruise ", the scope making vehicle can add and subtract 9% again by predetermined ideal vehicle speed value fluctuates, and the travel operation program that " work " (adding 9% during acting accumulation of energy) performed in this theory of automatically switching respectively is different with " spare time " (subtracting 9% when leisure is slided) these two.

The job procedure of " cruise ", respectively by the mode of again stepping on " braking " or " throttle " pedal, namely exerts one's influence to the corresponding speed of a motor vehicle consciously, changes this sole mode of the speed of a motor vehicle, automatically terminates the former setting of " cruise ".

(2) the energy resource consumption principle of " distribution according to need, according to quantity supply " is fully demonstrated

" distribution according to need " and " supplying according to quantity " is the supreme principle that the energy uses, and can show the natural effect of " make the best use of everything, show what one's be, respectively open up its, put and end to waste ", one of this theory large shining point just.After vehicle travels and reaches the desirable speed of a motor vehicle, chaufeur close the throttle, when actuating device is automatically changeb to " spare time " by " work " at once, just no longer expend the interior continuation traveling of scope that the energy also also remains on the desirable speed of a motor vehicle, meet and do not consume energy in the distance of 3/4, an epitome of principle of not distributing according to need just, supply according to quantity

(3) simple, the ultrahigh in efficiency of principle

This theory, directly employ vehicle self produce instantaneously in dynamic driving process and simultaneously again dynamic be stored in the inertia kinetic energy of self, centre is not through other transformation of energy mechanism any, and therefore also just without any other degradation of energy, its capacity usage ratio should be higher.For inertia kinetic energy, it is vector, has dynamically and give birth to, static state and the objective law of dying.It is dynamic and give birth to, deposits with garage, stops and stop with car with car, similar with the electric energy run in electrical network, have namely need not die, should not store, need not white no distinguishing feature.

This theory creates inertia kinetic energy instantaneously by " work ", have passed again the orderly release that " spare time " ensure that inertia kinetic energy, and not through other intermediate link any, though principle is simple, efficiency is high.

(4) solid foundation, failure-free control

Society has developed into the epoch of intelligent information, and reach and just can control accurately instantaneously, especially the fast development of electronics industry is directly the realization of this theory, inscribes and provide very superior objective material conditions before creating indispensable history.

(5) numerous and diverse " effect balance " has been tried to achieve with simple " mode "

The driving engine of existing vehicle is difficult to the mutual balance of accomplishing energy resource consumption and actual usefulness, and the actuating device (driving engine) in this theory, efficiently utilize work and these two kinds of diverse motoring conditions not busy instantaneously, carry out natural combination very cleverly, with the simplest driving mode deficiencies such as (only travel with accelerating mode and instead of various working and travel) of having avoided that the power consumption self existed is excessive, applicable area is narrow and small on one's own initiative, achieve the mutual balance of power consumption and actual benefit preferably.

(6) adaptation is actual, easy to operate

This theory adapts to the actual conditions in urban traffic road.Because in the road of city traffic, the concrete restriction having the instant change of traffic signal lamp, have the upward slope of overpass and descending, have the traffic facilities such as four corners, in fact the vehicle that urban traffic road is run has been caused, in concrete sections of road process, must have have less more, have anxious have slow, have stop having sail, the phenomenon of faster or slower occurs, and these, just this theoretical work and not busy traveling theory is met, the condition of " passive " can be converted into the driving of " initiatively ", embody the Driving of " prediction (precognition) property " fully.As: through junction ahead, make good use of work and not busy manipulation in good time, crossing can be avoided consciously to wait for red light (going to reconcile by speed).

(7) applicable area of this theory

This theory is applicable to the actuating device of all self-propelled vehiclees and all power actuated vehicles.Because they all also exist: as long as vehicle travels, just there will be that this is common, objectively, natural inertia kinetic energy, so, this theory is applicable to automobile, diesel-powered vehicle, Light-duty Vehicle, heavy goods vehicles, compact car, minicar, the power actuated vehicle that electric car, pollution-free buses using natural gas fuel, railcar, trolley-bus etc. are all even.

(8) with the relation of other scientific and technological achievement

This theory receives now all can be blended in it one well for all scientific and technological achievements in vehicle drive unit completely, and on its existing basis, also can energy-conservation half (50%) left and right again.As: clean fuel self-propelled vehicle, battery-driven car that modern science and technology content is very high, also on the basis of implementing this theory good, under the front topic making good use of " inertia kinetic energy ", can also continue energy-conservation half (50%) energy.

(9) brake efficiency is improved

Brake pedal should increase perceptron (sensor), can according to suddenly stepping on, heavily stepping in various degree, control the two states of the not busy power-transfer clutch of work respectively, utilize Jake brake traction resistance fully, category takes interior endergonic brake mode to greatest extent.

A. when chaufeur has gently stepped on brake pedal, master brake cylinder is started working, and produces brake-pressure and produces certain braking effect by each brake cylinder.

B., when chaufeur suddenly steps on brake pedal (heavily stepping on), on the basis of a. braking effect, force again the not busy power-transfer clutch of work to force to combine, start to use the traction braking resistance of driving engine to carry out comprehensive braking veritably.Driving engine does not now work (not fuel feeding, misfire), and its " traction braking resistance " should be larger.

(10) problem should avoided

When driving the vehicle of this theory, crucial at the conscious good driving habit forming the in good time exchange in " work and spare time ", keep vehicle will travel all the time in the scope of the desirable speed of a motor vehicle, certainly, this needs a process just can grasp skill, necessarily fit well being reluctant to does not leave throttle, must guard against the drive manner adopted and at the uniform velocity travel.

(11) the corresponding coupling of the speed of a motor vehicle and gearbox-gear is kept at any time

No matter whether driving engine is in work, all will realize the speed of a motor vehicle and the corresponding all the time coupling of gearbox-gear, that is: all will meet the basic demand of " what what shelves of speed " at any time.Propose gearbox-gear no matter dynamically or all need the dynamic new demand (referring to the vehicle of automatic gear) of mutually mating with current vehicle speed in a static situation.

(12) efficiency of work spare time driving how is improved

This theory is a system engineering, first will improve pickup of engine can be the key link of raising the efficiency with all strength, this theory opposes the way of high load with small power, advocates that what horse just draws the thinking of what car, and promotion allows pony become large horse, the method for weak horse grow horse goes to raise the efficiency.

(13) single-minded the going of actuating device is allowed to drive vehicle

Because the actuating device in this theory is out-of-run in the stroke of 3/4, the facility such as power assistance pump for steering, air-conditioning all does not directly go to drive with it.

(14) also in-engine lubrication to be ensured under not busy state

Dynamically store up the method for pressure device with increase engine oil path, when keeping shutting down, (in 2 minutes) also also have lubricating oil at lubricate, are beneficial to it and again start at any time.

(15) usefulness that accumulator capacity improves electrical generator is increased

In the stroke of 3/4, electrical generator and driving engine are all out-of-run, for ensureing the normal traveling of vehicle at night, all will a little time be descended to put into practice in generating and accumulate more.

(16) capacity and the usefulness of starter motor is improved

The frequency of usage of starter motor is high, and its capacity, usefulness all need further raising.

(17) the not busy power-transfer clutch of full-time work is increased

Although there is kinds of schemes all can realize the function of the not busy interval of work, in general still easy with the project plan comparison of the not busy power-transfer clutch of full-time work.Install the not busy power-transfer clutch of work additional at output shaft of gear-box tail end, control its automatic clutch by Das Gaspedal, force it to combine fast with when heavily stepping on (suddenly stepping on) brake pedal.In whole stroke, it should be under the state that will be in separation in the distance of 3/4.

(18) degree of intelligence of this theoretical system is improved

First degree of intelligence and the fiduciary level of hardware (device) is emphasized.As: with the opening of Das Gaspedal automatically controlled engine, stop with work not busy power-transfer clutch automatic from, close (meeting the synchronous requirement combined), force the aspects such as the not busy power-transfer clutch combination of work must ensure the intelligent of them and reliability with anxious brake pedal of stepping on, also will develop " the not busy Intelligent control apparatus of work " and corresponding software facilitates chaufeur to manipulate (self-learning function) simultaneously.

Four, accompanying drawing explanation

five. specific embodiments

The core of this theory be the instantaneous work of vehicle and not busy two kinds of different motoring conditions constantly alternately, repeatedly upgrade; Its essence is the energy resource consumption principle that follow through performs vehicle drive unit (driving engine) distribution according to need, supplies according to quantity; Its key is realizing work, the approach in spare time and the method for manipulation.

Increase the not busy power-transfer clutch of work in existing car transmissions change speed gear box rear end, making it have can fast shut-off, just can remove again the two major features combined when the mutual match synchronization of the rotating speed of driving engine and the speed of a motor vehicle instantly.

When chaufeur depresses Das Gaspedal, when first requiring the rotating speed of driving engine and speed of a motor vehicle simultaneously match (minimizing impact wear) at that time, the not busy power-transfer clutch of work just can be made to be in the state of joint, directly to obtain the power (power or moment of torsion) of driving engine, when being incremented to rapidly the desirable speed of a motor vehicle, Das Gaspedal is unclamped by chaufeur again, after making it naturally reset to initial condition, vehicle performs the program in " spare time ", the not busy power-transfer clutch of work is allowed to be in the state of quick separating, with the supply of the power transmission chain of fast shut-off driving engine and the driving engine energy, want driving engine stall immediately on the one hand, more to make full use of the inertia kinetic energy of vehicle on the other hand, the interior continuation of scope remaining on the desirable speed of a motor vehicle travels.When the speed of a motor vehicle can not make chaufeur be satisfied with again, chaufeur can depress Das Gaspedal again again, start again the work of next round, not busy alternately and replacing, until when completing current traveling task.In the overall process that vehicle travels, it is real moment " walk around and stop " that driving engine belongs to, driving engine so start and stop frequently need not be worried, because it works, so its frequent start-stop should become problem under the environment lubricated in, machine unloaded, zero load in heat engine.

This scheme also all will need to make to the existing auxiliary facilities such as a/c system, power assistance pump for steering, braking moved by engine direct tape splicing of vehicle to be improved and adjustment.This is mainly because driving engine will stop operating the inevitable outcome that (not working) reason causes in the operating range of about 3/4.
