Electronic accelerator control method

Abstract

The invention relates to restrictor control technology, in particular to an electronic accelerator control method. The electronic accelerator control method is characterized in that: a restrictor control shaft of a throttle valve is connected with a shaft sleeve by a shaft, the shaft sleeve is connected with a motor shaft sleeve through a stay wire, a motor and a controller are fixed in a shell, a differential capacitance angle transducer is arranged between the motor shaft sleeve and the output shaft of the motor, two fixed electrode plates of the differential capacitance angle transducer are fixed with the shell, and one dynamic electrode plate of the differential capacitance angle transducer is fixed with the output shaft of the motor; after receiving an accelerator control command, the controller controls the rotation of the motor according to the command of the controller and the capacitance of the differential capacitance angle transducer; and the output shaft of the motor drives the motor shaft sleeve to rotate, the motor shaft sleeve drives the shaft sleeve to rotate through the stay wire, and the shaft sleeve drives the restrictor control shaft to rotate. The invention provides the electronic accelerator 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.
