Description
Technical field
The present invention relates to the mechanical drive field of sensing technologies, be specifically related to various mechanical drive medium speeds, the isoparametric sensing of load are related in particular to the Torsional mechanical torque, rotation speed, angle and displacement driving sensor of motorcycle, electric bicycle.
Background technology
In mechanical drive, to realize intelligent transmission control, load is important test item, and no matter present is on common gearing, still on vehicle, measurement to this index generally is to adopt multiple sensor to obtain correlation parameter respectively, comes comprehensive judgement again.Load detection scheme as existing automobile, motorcycle:
A) 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 that 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.
B) 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, admission pressure also can change thereupon, differentiate the variation of load, detection load with intake manifold pressure sensor.
These two kinds of schemes, 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 under the bearing load indirect mode at vehicle front and to detect, and be that detection is judged resulting on engine, conforming requirement is strict to engine in this measurement, and often engine production producer can't guarantee, each engine will carry out strict demarcation separately; Air inlet pressure sensor cost height, and the admission pressure fluctuation is bigger, fluctuation generally also can appear in admission pressure, and inlet valve disassociation valve body distance is very short, and the admission 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, usually make artificial maloperation, the inaccurate demand of engine that misled of people's maloperation and operation to load, and engine can be 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.Engine is to produce the power source that drives, the power that all gear trains after the engine transmission output are brought and variation, travel conditions and the various complex working condition of loss in efficiency and load all detect and control, therefore the detection to system of vehicle 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 testing agency's complexity, cost height, sexual valence ratio.
Summary of the invention
