Problems solved by technology

In the early days, the potentiometer here was a sliding resistance type, which has many disadvantages, because it has contact points, is easy to wear (rotation life: about 3 million times), poor reliability, and the occasional electric spark will interfere with the ECU. Working status (thus burying potential safety hazards) and many other shortcomings

Abstract

The invention relates to a non-contact automobile electron accelerator angle sensor, in particular to an automobile electron accelerator angle sensor which arranges a positioning pressing ring and a transverse bolt inside the traditional magnetosensitive non-contact angle sensor so as to realize the accurate positioning. The non-contact automobile electron accelerator angle sensor comprises a sensor body, a rotating shaft, the positioning pressing ring, a magnet, the transverse bolt, epoxide resin, a spring, a circuit board and a sensing unit mounted on the surface of the circuit board. The basic principle of the non-contact automobile electron accelerator angle sensor is that: when the automobile accelerator pedal drives the rotary magnet to rotate in a non-contact way above the sensing unit, magnetic lines are cut by magneto sensors in the sensing unit to induce the changing voltage signal, and the linear voltage signal is output after being processed by the microprocessor and the digital signal processing circuit which are integrated in advance in the sensing unit. The linear voltage signal is used for changing the working condition of the automobile engine. The interior installation of the non-contact automobile electron accelerator angle sensor of the invention greatly improves the accuracy and the reliability of the magnetosensitive non-contact angle sensor, and prolongs the service life thereof.

Description

(1) Technical field [0001] The present invention relates to a non-contact automotive electronic throttle angle sensor, in particular to a precisely positioned non-contact automotive electronic throttle angle sensor. An automotive electronic throttle angle sensor with a ring and a horizontal pin. (2) Background technology [0002] As we all know, in the running of a car, the traditional engine control mechanism works through a cable (soft steel wire) or a pull rod, one end of which is connected to the accelerator pedal, and the other end is connected to the throttle linkage plate. However, the scope of application of this traditional throttle is limited and lacks precision. Under the ever-changing development of automotive electronics technology, electronic throttle has emerged as the times require. After the engine of the car using the electronic accelerator is started, the accelerator pedal is in a fully relaxed state. When the driver starts to step on the electronic accel...
