Description
Technical field:
Engine power control---electronics module control system
Background technique:
Automobile energy-saving technology produces so far from automobile that countless people are making great efforts for it in batches, has obtained huge achievement to today.Simultaneously power-saving technology has proposed new challenge to the rate of energy problem again when today that non-renewable resources consume gradually and automobile rapidly enter huge numbers of families! This explanation will be talked about from automobile fuel saving technology, analyze the design principle and the development space of new approaches, wish that this technology can bring new progress for world's vehicle fuel conservation techniques!
The development of fuel saving technology: the fuel saving technology has so two big aspects nothing but for vehicle:
Be artificial driving on the one hand, the driving habits by some fuel savings reaches fuel-efficient purpose;
Be exactly Products Development on the other hand, this comprising: reduce tare, reduce the engine running resistance, reduce air resistance coefficient, reduce aspects such as running system resistance.Develop more senior engine technology, for example variable valve timing technology (VTEC), variable air inlet length of tube technology (VVTI), turbocharging technology, Lean Burning Technique (in-cylinder direct injection), dual ignition technology or the like.These technology have not only been improved the performance of motor, have most importantly reduced fuel consume, have strengthened the power of motor.
The fuel saving product be installed in the effect of having played fuel saving to a great extent.They mainly be by technological means allow fuel oil with air mixing before by better atomizing, ionization or heating, thereby better and air mixing make burning more abundant!
Summary of the invention:
And " controlling the fuel saving technology automatically " that I propose is exactly to have added a friend---automatic fuel-saving system between automobile and driver, reaches on the basis that former car designs the purpose of fuel saving more.Below I am described in detail with regard to this technology.
Technological scheme:
First let us is seen a theory analysis before the control principle of understanding the conservation of fuel control module:
(annotate: the parameter of Chu Xianing is only done signal herein.)
Suppose that certain vehicle (being regardless of fuel type) empty wagons is on straight calm highway during straight-line travelling, flow is 9ml/s at the fuel feed line place, when fuel return line place flow is 6ml/s, the oily 3ml of per second, speed per hour is the 43.2km/h vehicle per second 12m that travels, and is equivalent to every milliliter of fuel 4m that travels; At per second during with oily 4ml, speed per hour is 86.4km/h vehicle driving 24m equally, is equivalent to every milliliter of fuel 6m that travels; Be 90km/h in the speed of a motor vehicle equally, the vehicle per second 25m that travels when being equivalent to per second with oily 5ml is equivalent to every milliliter of fuel 5m that travels; Equally at per second during with oily 8ml, speed per hour is the 115.2km/h vehicle per second 32m that travels, and is equivalent to every milliliter of fuel 4m that travels; In view of the above, I have drawn an above-mentioned schematic diagram data.(seeing Figure of description Fig. 1)
The same fuel consume curve of parabola has just appearred in fuel consume under the situation of the single condition changing speed of a motor vehicle, the actual conditions of vehicle driving are the same with above principle in fact, the increase that acceleration resistance, wind resistance, resistance due to climbing, descending resistance (resistance is a negative value), load-carrying are loaded, turning resistance or the like have just been increased in the process of moving, these resistances are all in the fuel consumption that increases every kilometer, so the actual conditions difference of various cars has caused this fuel economy optimum in continuous variation.Can catch this optimum so in this day and age, allow vehicle always be in the state of fuel saving in motion? if only the operation by the people misses one's aim certainly.But the science and technology of our today could reach or meet this requirement fully! " controlling the conservation of fuel technology automatically " of these less important research and development that Here it is.This innovative technology is that a kind of full automatic optimum fuel is saved and driven control, utilizes modern electronic technology and computer program control technique, is applied to automotive fuel and saves control system, reasonable in design, simple to operate, effect is obvious, applied widely; The fuel saving control ability is near the most economical oil consumption district of producer's test.Be applicable to various various automobiles, motorcycle, the steamers of doing fuel generation power with liquid, gas; Be applicable to various forms of engine fuel controls.Integrability also can install additional separately.Be particularly suitable for often walking long-distance car, lorry, passenger stock and steamer or the like.
How is this technology controlled actually so?
Whole system comprises that a fuel saves control single chip computer (circuit theory diagrams provide) automatically, two fuel flow sensors are (according to institute's survey fuel vehicle vehicle consume fuel speed different choice flow transducer, in experimentation, simulate the signal of two fuel flow sensors with signal simulator, this sensor can be predetermined in manufacturer as required), (program and the motor of experiment usefulness all are common twin wire 12V direct current motors to an output motor, also can adopt four-wire type 12V stepping motor in practice), the reduction gears mechanism that motor is relevant (adopts direct closure during experiment, so there has been ready-made reduction gears mechanism the inside), (this backguy is installed at the place in the easiest application of force of gas pedal in the backguy of final connection gas pedal, to realize the control of motor to throttle), vehicle speed signal is directly obtained or obtained from the wheel speed sensors of some wheels from vehicle output shaft vehicle speed sensor does not need additional sensor; Other comfort system signals are connected to former car region of interest as required.
Control principle schematic representation such as Figure of description 2.
The calculating principle of controlling computer: 1000/ each second of vehicle speed per hour * is with fuel quantity=every milliliter of distance that fuel can travel.
If not stepping on from throttle, be divided into 100 even positions to the throttle low state of stepping on, that single-chip microcomputer just drives the gas pedal control motor pedal (each unit change amount of positive action) of stepping on the throttle successively and the speed of a motor vehicle is risen measure then and calculate new result, when every milliliter of fuel operating range of next measuring point is measured less than this, again gas pedal is reclaimed (each three unit change amounts of counteragent), and then measure and calculate, contrast with the last time again, just continue to reduce gas pedal control than last also little that, if it is far away than the last time, that single-chip microcomputer just drives the gas pedal control motor pedal (each unit change amount of positive action) of stepping on the throttle successively, and then measure and calculate, seek optimum again and realize the conservation of fuel closed loop work cycle of control automatically so repeatedly.
System works schematic representation such as Figure of description 3.
Energy-saving control module control principle data signal table is seen the subordinate list of the last page or leaf of specification.
Annotate: the Throttle Opening Control motor can be that dutycycle controlling type two line motor also can be stepping motors three-way or four line traffic controls, when dutycycle increases, the motor drives gas pedal is to the direction action of stepping on the gas, when dutycycle reduces, thereby the drive gas pedals such as gas pedal spring that motor is subjected to the control force of electricity to reduce former car are moved to the direction of unclamping gas pedal.And the control signal of stepping motor is not a dutycycle, but electrical pulsing signal, and under the situation that does not add electrical pulse, automatically lock after the stepping motor action.Be equivalent to the open out operation and subtract throttle operation.
System works overall process principle:
This project is to have made to add on the basis of performance the single-chip microcomputer conservation of fuel program of control automatically not influencing former turner.Open conservation of fuel general power control switch when normal vehicle operation, the fuel consumption analogue signal shows in the test display screen in speed of a motor vehicle virtual signal and unit time.Conservation of fuel control program tutorial light is 1 bright, and system wait enters the conservation of fuel control program.Point touches the conservation of fuel control knob, and buzzer sends first kind of sound, and conservation of fuel control program tutorial light 1,2 is bright, and system begins automatic adjusting, also has can the travel analog amount of maximum distance of a position display calculating optimum fuel consumption in the test display screen.Just can unclamp gas pedal as opening cruise control this moment, the conservation of fuel control program begins executable operations, make Vehicle-Miles of Travel longer no matter which gear conservation of fuel control module can adapt to the optimal economic oil consumption automatically in, (the automatic transmission vehicle preferably vehicle is walked to the most high-grade after otherwise open conservation of fuel control program vehicles at other gears and might not rise to the most high-grade).When vehicle is done the operation or go up a slope or head-on the wind comes from when air resistance coefficient is increased because engine load increases of turning, this moment, fuel consumption rate can raise, the conservation of fuel control module can be felt in the very first time, and the Throttle Opening Control motor is implemented to subtract Throttle Opening Control (each three unit change amounts of counteragent or stepping motor retreated for three steps).The sensor of conservation of fuel control module is also at the special parameter that is constantly monitoring system works simultaneously.Oil control is excessive when subtracting, the conservation of fuel control module can be carried out refueling control automatically, allow gas pedal control motor be subjected to refueling control (each unit change amount of positive action or stepping motor take a step forward), be increased to when surpassing optimal fuel economy the conservation of fuel control module and can carry out automatically and subtract oil control gas pedal control motor and subtract Throttle Opening Control (each three unit change amounts of counteragent or stepping motor retreated for three steps), and then carry out refueling control (each unit change amount of positive action or stepping motor take a step forward) so repeatedly.When the vehicle descending or when head-on air resistance coefficient reduces since engine load reduce, this moment, fuel consumption rate can reduce, the conservation of fuel control module can be felt in the very first time, and gas pedal control motor is subjected to refueling control (each unit change amount of positive action or stepping motor take a step forward), excessive when refueling, the conservation of fuel control module can make the Throttle Opening Control motor implement to subtract Throttle Opening Control (each three unit change amounts of counteragent or stepping motor retreated for three steps) and then refuel or subtract oil more also to be so repeatedly when having surpassed best fuel consume.So just fuel consumption rate has been controlled at (virtual condition is near motor drives gas pedal little fast quivering optimal economic consumption location) near the best time, thereby has realized that conservation of fuel controls automatically.Need hot refueling when vehicle runs into urgency, step on clutch, change when doing neutral or brake, the driver can be from the gas pedal or the braking pedal of the relevant control of line operate.If short-term operation conservation of fuel control module Control work tutorial light 3 is lighted, the expression control program withdraws from temporarily, driver's cancellation is to the operation of gas pedal or braking pedal in 5 seconds, and the conservation of fuel control program recovers automatically, recovers back work indicator light 3 and extinguishes.When driver's executable operations above 5 seconds, be considered as the intentional cancellation conservation of fuel of driver control program, work indicator light is lighted by 123 in 5 seconds, represent interim exit status, work indicator light 2,3 extinguishes after 5 seconds, have only 1 to withdraw from this expression of light yellow, prepare to enter working state, buzzer sends second kind of auditory tone cues Energy Saving Control program pattern of having deactivated simultaneously.
Under the normal situation of a cutting system, when opening this function, can occur just like Figure of description 4 curve synoptic diagram that travels,
The curve lexical or textual analysis:
OA section: after opening Energy Saving Control during for the former speed of a motor vehicle, if the former speed of a motor vehicle is higher than target vehicle speed, then energy-saving control module drives the Throttle Opening Control motor and implements to subtract Throttle Opening Control (each three unit change amounts of counteragent or stepping motor retreated for three steps) and then refuel or subtract oil again, up to the optimal economic speed per hour; If the former speed of a motor vehicle is lower than target vehicle speed, then energy-saving control module control gas pedal control motor is subjected to refueling control (each unit change amount of positive action or stepping motor take a step forward), up to the optimal economic speed per hour.
AB section: the adjustment collection of illustrative plates of energy-saving control module during for cruising, each energy-saving control module control gas pedal control motor is subjected to refueling control (each unit change amount of positive action or stepping motor take a step forward), after rising, certain has surpassed the lowest economic speed per hour when detecting, three unit change amounts of the each counteragent of motor control gas pedal then, unit change amount of exploratory again positive action is regulated successively like this.
BC section: when vehicle meets obstructions, optimal economic speed per hour will descend (for example: upward slope, turning, frontal resistance increase, road surface condition variation or the like), energy-saving control module drives the Throttle Opening Control motor and implements to subtract Throttle Opening Control (each three unit change amounts of counteragent or stepping motor retreated for three steps) and then refuel or subtract oil again, up to optimal economic speed per hour point.
CD section: implement normal control, characteristics such as collection of illustrative plates AB section at new optimal economic speed per hour point.
The DE section: when vehicle meets obstructions when reducing, optimal economic speed per hour point is rise (for example: descending, increase, road condition change etc. with the wind); Energy-saving control module The driving motor control gas pedal is just as the OA lower semisection, and each unit change amount of positive action is up to reaching new optimal economic speed per hour point.
EF section:, keep the optimal economic speed per hour as AB section or CD section state.
The FG section: when step on clutch, brake, when extension neutral signal reaches the economizer control module, conservation of fuel control module identification of driver will carry out manual operation, temporary withdrawing from; When cancelling its associative operation Deng the driver, the conservation of fuel control module is recovered the control to the accelerator pedal position of motor control.As: the GH section.
HI section: when stepping on the gas, the conservation of fuel control module receives that driver very important person (can extract throttle valve position signal for the signal that quickens, also can design the extracting mode of this signal separately, even do not extract this signal, the control motor has been relaxed state to the backguy of gas pedal when pin is stepped on the gas artificial the acceleration, program does not influence vehicle operating and Safety performance yet so computer is not deactivated), use often when general this situation is overtaken other vehicles, conservation of fuel control function does not withdraw from but does not influence the driver and quickens, when the driver cancels operation, conservation of fuel control functional rehabilitation.
The IJ section: the control functional rehabilitation, find new optimal economic speed per hour point.
The JK section: when vehicle drag die-offs, energy-saving control module fails to reach the optimal economic speed per hour in certain a long time, damages motor and the speed of a motor vehicle is too fast for preventing that engine speed is too high, and energy-saving control module control function withdraws from, and waits for driver's operation; At this moment, motor is got back to idling mode automatically, and vehicle is implemented anti-dragged brake, has guaranteed the Security of vehicle driving; When vehicle drag increases suddenly, energy-saving control module controls to idling mode with vehicle and does not also reach the optimal economic speed per hour in certain a long time, and then conservation of fuel control function withdraws from, and waits for driver's executable operations.
So repeatedly, just form the full automatic closed loop control between the speed of a motor vehicle and the specific fuel consumption, thereby reached the purpose of fuel saving.
The project sketch is seen Figure of description 5.
This working procedure is closed loop control, and main input signal is actual vehicle speed signal and fuel flow signal.The major control signal is engine idle signal, coolant temperature signal, brake signal, accelerator pedal position signal, neutral switch signal, reverse gear switch signal, clutch pedal signal and manual switch signal.Main output signal is the accelerator pedal position motor drive signal; Less important output signal is work indicator light, fuel flow display device, double-tone buzzer.The effect of conservation of fuel control single chip computer is exactly to analyze the speed of a motor vehicle of the fuel oil use amount correspondence the longest distance of whether travelling, if the longest distance of can not travelling is so by reducing that the gas pedal application of force is made the throttle self-return, engine load reduces,, speed is lower than most economical speed per hour if having reduced, at this moment conservation of fuel control single chip computer control increases the power of gas pedal, suitable and throttle is operated, thereby goes for optimal economic speed per hour point again.The signal sampling frequency should be greater than 1HZ less than 5HZ, but can not be too fast, because can causing quickening the too fast motor that makes, too fast adjusting frequency quicken mild membership dues oil (concrete can also regulate computer program reach optimization control) according to vehicle motor characteristic difference.
