The gasoline-saving device linkage structure schematic diagram that Fig. 1 provides for the embodiment of the present invention.
In upper Fig. 1:
Gasoline-saving device body 1, CAN 2, ECU3, multistate switch 4, motor 5.
Embodiment
In order to make those skilled in the art understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1, the gasoline-saving device linkage structure schematic diagram that Fig. 1 provides for the embodiment of the present invention.
The English full name of ECU is Electronic Control Unit, and Chinese is electronic control unit, and the English full name of CAN is Controller Area Network, and Chinese is for being controller local area network.
The gasoline-saving device that the embodiment of the present invention provides, comprises gasoline-saving device body 1, multistate switch 4, ECU3 and CAN 2, and gasoline-saving device body 1 is connected with ECU3 by CAN 2, and multistate switch 4 is connected with ECU3.During use, after car load accesses gasoline-saving device provided by the present invention, driver can according to the state of Current vehicle load, by selecting the different gears of multistate switch 4, motor 5 is made to send proper power and moment of torsion, such as when zero load, fully loaded even load situation, be selected in multistate switch 4 at different gears, allow vehicle all can reach tentatively fuel-efficient object under different load conditions.
Simultaneously, carry out monitoring in real time by gasoline-saving device body 1 pair of engine working point and judge, certain intervention is carried out to the bad steering behavior of driver, engine working point is finally made to be distributed in the region of better economy, complete-vehicle oil consumption is made to reach minimum, every platform motor 5 region that all oil consumption is low, this region is considered as the region of better economy; Simultaneously, gasoline-saving device body 1 comprehensively can also analyze the driving cycle (comprising the variablees such as Engine torque, the speed of a motor vehicle, throttle size, driver intention) of vehicle, the sudden change oil mass of real-time intervention motor 5 exports, control the fluctuation of the fuel delivery of motor 5, by fluctuation restriction within the specific limits, avoid unnecessary urgency to accelerate and oil mass fluctuation, thus reduce the comprehensive oil consumption of car load.
In order to optimize such scheme further, above-mentioned gasoline-saving device also comprises and the actual provision oil mass depressing demand oil mass corresponding to position and previous moment of gas pedal being contrasted, maximum value restriction is carried out to both variable quantities of difference, object makes Engine Injection Mass steadily increase Appropriate application, wherein, the Amount of actual oil supply of previous moment can be thought to carry out maximum value restriction to variable quantity between the two by the Amount of actual oil supply of gas pedal position before arrival depresses position.Maximum value is herein artificial setting, previous moment herein can be specifically artificial setting, the concrete previous moment can thinking a unit time, in second, can be understood as between unit: the increase of the fuel injection quantity within the unit time has CLV ceiling limit value herein.This CLV ceiling limit value is definite value, even if the very fast or gas pedal of the speed that depresses of gas pedal is shaken when jolting like this, all can not cause the swift and violent change of fuel injection quantity.
Certainly, can be gasoline-saving device body 1 according to engine speed, gas pedal aperture, Engine torque, torque demand is provided to gas pedal, does not allow surging in the extremely short time, restricted to the upper limit of its fluctuation at short notice, realize judging and intervening with this.By limiting engine peak speed in running, realize making motor 5 be operated in most economical oil consumption district.
The present invention also provides a kind of fuel saving method, adopt gasoline-saving device body 1, multistate switch 4, ECU3 and CAN 2, gasoline-saving device body 1 is connected with ECU3 by CAN 2, multistate switch 4 is connected with ECU3, and wherein, driver is according to the state of Current vehicle load, by selecting the different gears of multistate switch 4, control power and the moment of torsion of motor 5, gasoline-saving device body 1 pair of engine working point carries out monitoring in real time and judges, controls the region that engine working point is distributed in Economy.Thus reduction oil consumption.
In order to optimize such scheme further, gasoline-saving device body 1 controls the fluctuation of the fuel delivery of motor 5, by fluctuation restriction within the specific limits, reduces oil consumption further.
Apply specific case herein to set forth principle of the present invention and mode of execution, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
