Description
Technical field
The present invention relates to motorcycle part, be specifically related to a kind of self adaptive sensing device for transmission on motorcycle.
Background technique
At present, motor car engine has entered automatically controlled and EFI period, uses the epoch of Carburetor to become history.The structure of motorcycle engine and the structure of motor car engine are very approaching, and what have also begins to adopt electric jet technology, but owing to multiple reason, do not obtain so far promoting, so motorcycle is still using carburetor oil-supply system.Take to be rigidly connected between its throttle control handle and the Carburetor, directly control amount of fuel and air quantity, driver's manual operation is depended in the adjusting of startup, acceleration, deceleration, idling and closure fully, the signal that throttle control handle provides is usually inconsistent with the motorcycle operating conditions, cause the moment of torsion of motor output and rotating speed and the needed load of motorcycle actual conditions not to match, more can not realize quantitative control.Therefore, the oil supply system of motorcycle being carried out intelligent control, get rid of artificial factor, is to improve the effective way that the Motorcycle Market competition is participated in.Carry out intellectuality control to the oil supply system of motorcycle, load or moment of torsion are important detection indexs.Measurement to this index generally is to adopt multiple sensor to obtain relevant parameter respectively, comprehensively judges again.As adopt throttle position sensor and speed probe to judge load, promptly so-called a-n system.Wherein, a dactylus valve position, n refers to rotating speed.ECU thinks, the same then load in the position of throttle opening is the same, and the position of throttle opening is different then loads differently, measures with this and to detect the difference of judging load.And for example adopt intake manifold pressure sensor and speed probe to judge load, promptly so-called p-n system.Wherein, p finger pressure power, n refers to rotating speed.Because load variations, suction pressure also can change thereupon, so, differentiate the variation of load, detection load with intake manifold pressure sensor.The oil spout that load difference causes changes by the lambda sensor correction.
These two kinds load detection systems all are all not participate in transmission directly at the sensor, do not have to detect under the bearing load indirect mode at vehicle front, and are that detection is judged resulting on motor.This measurement is strict to the conforming requirement of motor, and often engine production producer can't guarantee, must carry out strict demarcation separately to each motor.And the suction pressure fluctuation is bigger, and fluctuation generally also can appear in suction pressure, and intake valve disassociation air door body distance is very short, and the suction pressure fluctuation is bigger, makes ECU judge that real load is inaccurate.Because the operating mode of vehicle operating is extremely complicated, the people can not make accurately and judging, artificial misoperation usually takes place, misled the demand of motor to load, motor is then carried out according to people's operational order fully, also be based upon on the inaccurate basis even proofread and correct, therefore, cause oil consumption loss and loss in efficiency.Motor is to produce the power source that drives, the power that all driving mechanisms after the motor transmission output are brought and variation, running condition and the various complex working condition of loss in efficiency and load all detect and control, therefore the detection to motorcycle transmission and change in torque situation is local, and judgement that microcomputer is done and the instruction of sending are all not exclusively rationally with accurate.And feeler mechanism's complexity, cost height, sexual valence ratio.
