A kind of electronic throttle control method

Abstract

The invention relates to throttle control technology, in particular to an electronic throttle control method, which is characterized in that: the throttle control shaft of the throttle valve is connected to the shaft sleeve shaft, the shaft sleeve is connected to the motor shaft sleeve through a pull wire, and the motor and the controller are fixed on In the shell, there is a differential capacitive angle sensor between the motor shaft sleeve and the output shaft of the motor. Two fixed electrode pieces of the differential capacitive angle sensor are fixed to the shell, and one moving electrode piece of the differential capacitive angle sensor It is fixed with the output shaft of the motor. After the controller receives the throttle control command, it controls the motor to rotate according to the command of the controller and the capacitance of the differential capacitive angle sensor. The output shaft of the motor drives the motor shaft sleeve to rotate, and the motor shaft sleeve passes through the The pull wire drives the shaft sleeve to rotate, and the shaft sleeve drives the throttle control shaft to rotate. It provides an electronic throttle control method with long service life, safety and reliability.

Description

technical field [0001] The invention relates to throttle control technology, in particular to an electronic throttle control method. Background technique [0002] Due to various reasons such as environmental protection, economy, reliability, etc., newer models now generally use electronic accelerators. The so-called electronic accelerators are aimed at the previous pull-wire accelerators. The traditional pull-wire accelerators directly connect the accelerator pedal to the The solar terms are connected, and the depth of the accelerator pedal directly corresponds to the opening and closing of the solar terms. [0003] The characteristic of the traditional pull-wire accelerator is that the system is simple, the control is direct, and the opening of the accelerator pedal and the throttle is 1:1; while the characteristic of the electronic accelerator is that the accelerator pedal only represents the driver's operation intention, and the final control of the throttle is handed ove...

AI Technical Summary

Problems solved by technology

[0005] Existing throttle position sensors mostly adopt the resistance detection method of potentiometer structure. The throttle position sensor with potentiometer structure has the problems of short service life and easy damage, which affects the reliability and safety of the electronic throttle control system.
