Problems solved by technology

[0006] Both of these two load detection systems are detected when the above sensors are not directly involved in the transmission, and the front end of the vehicle is not under the indirect state of load, and are obtained by detection and judgment on the engine. The requirements for the consistency of the engine for this measurement are Very strict, but often the engine manufacturer cannot guarantee that each engine must be calibrated separately; the cost of the intake pressure sensor is high, and the intake pressure fluctuates greatly, and the intake pressure generally fluctuates, and the intake valve The distance of the dissociated valve body is very short, and the intake pressure fluctuates greatly, which makes the ECU determine the real load inaccurately
Due to the extremely complicated working conditions of the vehicle, it is impossible for human beings to make accurate judgments, and often make artificial misoperations. Human misoperations and inaccurate operations mislead the engine's demand for load, and the engine will completely follow human operations. Command execution, even corrections, is based on an inaccurate basis, thus causing fuel consumption losses and efficiency losses
The engine is the power source for driving. It does not detect and control the power and efficiency loss and load changes, driving conditions and various complex working conditions brought about by all transmission mechanisms after the engine transmits output. Therefore, the vehicle transmission and torque The detection of changes is partial, and the judgments and instructions issued by the microcomputer are not completely reasonable and accurate
Moreover, the detection mechanism is complicated, the cost is high, and the cost performance is poor

Description

technical field [0001] The invention relates to the technical field of mechanical transmission sensing, in particular to the sensing of parameters such as rotational speeds and loads in various mechanical transmissions, and in particular to torque-type mechanical torque rotational speed angle displacement transmission sensing devices for motorcycles and electric bicycles. Background technique [0002] In order to realize intelligent transmission control in mechanical transmission, the load is an important detection item. At present, whether it is on ordinary transmission machinery or on vehicles, the measurement of this index generally uses a variety of sensors to obtain relevant parameters respectively. Then come to the comprehensive judgment. For example, the load detection scheme of existing automobiles and motorcycles: [0003] a) The throttle position sensor and speed sensor are used to judge the load, which is the so-called a-n system. Among them, a refers to the thr...
