Abstract
An oil-saving technique realized by improving the control strategy of IC engine for car features that its systems is composed of speed sensor, engine, clutch, automatic speed variator, electric control unit of IC engine, and the control program for judging the speed of car and running an automatic oil-saving strategy if the car is in low-speed or medium-speed state.
Description
Technical field
Patent of the present invention relates to a kind of fuel-economizing controlling method of internal-combustion engines vehicle, and especially a kind of part control program that only adds in internal-combustion engine electronic control unit (ECU) reaches the fuel-economizing controlling method that reduces the effect that internal-combustion engines vehicle running process intermediate fuel oil consumes.
Background technique
Because fossil energy is in short supply day by day, the fuel saving method of internal-combustion engines vehicle is always in continuous development.Fuel saving method to internal-combustion engine itself has achieving lean combustion in engine method, engine booster method, many valves and electronic fuel injection and port timing control etc.; The gearbox of increasing gear is arranged aspect car load usually, adopt novel power train (as mechanical stepless automatic speed changer (CVT), mechanical automatic speed-changing case (AMT)), adopt free wheel device, adopt radial-ply tyre, reduce Aerodynamic Drag Coefficient of Automobile etc.Above-mentioned some method is very perfect, and further excavating the fuel-economizing potentiality has suitable difficulty; Some method will increase the cost of automobile greatly.
Summary of the invention
The technical problem to be solved in the present invention is to carry relating to a kind of vehicle oil-saving method of realizing by the improvement internal combustion engine control strategy, and this fuel saving method is easy to implement, and cost is extremely low, has splendid application prospect.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of by improving the vehicle oil-saving method that internal combustion engine control strategy is realized, comprise the automotive speed sensor motor, clutch, automatic transmission case, internal-combustion engine electronic control unit.
In vehicle traveling process: the signal that the internal-combustion engine electronic control cell processing transmits from valve opening sensor and automotive speed sensor, and compare with a processing result and a fixing threshold value; If calculated value is lower than threshold value, open the fuel-saving control program, the control throttle opening, this cycle starting point is: motor carries out the transition to the higher zone of fuel economy rapidly, and automobile begins to quicken simultaneously; During near actual vehicle speed surpasses target vehicle speed limit value, the internal-combustion engine electronic control unit sends control signal to automatic transmission case, and automatic transmission case is transformed into neutral position; Reduce throttle opening, motor enters idling operation, and automobile begins to slide; During near the speed of a motor vehicle is lower than target vehicle speed limit value, the internal-combustion engine electronic control unit sends signal, make automatic transmission case recover gear, increase throttle opening simultaneously, at last, motor returns the higher zone of fuel economy, so periodically repeat, thus, motor is from the above-mentioned beginning that carries out the transition to the higher zone of fuel economy rapidly, return the higher zone of fuel economy to motor till, form periodic cycle, motor switches between idling and high fuel economy operating mode, realizes saving fuel oil.
The present invention does not need additional any component of internal combustion locomotive and sensor are only added the part control program in the internal-combustion engine electronic control unit.This fuel-saving control program will be judged the current driving cycle of automobile by accelerator open degree and automobile speed, then start the fuel-saving control strategy when hanging down speed of a motor vehicle cruising condition in being in as if automobile.This method makes motor always work in the higher zone of fuel economy, to reach the effect that reduces vehicle fuel consume.This fuel saving method is easy to implement, and cost is extremely low, has splendid application prospect.
