Line control air control shutter controller module and control method thereof

Abstract

The invention relates to a throttle-by-wire controller module and a control method thereof. The throttle-by-wire controller module is arranged between an electric accelerator pedal and the body of a throttle-by-wire and is provided with a host processor used for carrying out various control algorithms and respectively connected with an alcohol sensitivity sensor and a pedal position sensor by an analog quantity inputting interface as well as controlling the motion of a stepping motor by a PWM interface and a motor driver. The hardware structure of the invention runs the control algorithms of the throttle-by-wire and drives the stepping motor to move according to the control algorithms of the throttle-by-wire by collecting the signals from the pedal position sensor and the alcohol sensitivity sensor so as to finish controlling the throttle-angle. The invention integrates the function of 'adjustable driving property', in particular the function of 'monitoring and alarming for drunk driving', effectively reduces the danger for drunk driving, can meet the driving demands of the drivers with different types, can be communicated with other vehicle computers by a CAN bus interface integrated on the invention.

Description

Technical field [0001] The invention relates to the field of automobiles, in particular to a wire-controlled throttle controller module for controlling the air intake of an automobile engine and a control method thereof. Background technique [0002] Wire control technology originally originated from the aviation industry. After being introduced into the automotive industry, it is believed that it can effectively improve vehicle safety, performance and fuel efficiency, while reducing design and manufacturing costs. In the traditional mechanical throttle control system, there is a mechanical connection between the accelerator pedal and the throttle (through a zipper or connecting rod), and the driver directly controls the intake of the engine's intake manifold by stepping on the accelerator pedal. control. With the rapid development of computer technology and electronic technology, the shortcomings of this traditional mechanical throttle control mechanism are increasingly revealed...

AI Technical Summary

Problems solved by technology

[0004] 2. The rod-type control mechanism has the problem of mechanical wear and tear. The longer it is used, the less accurate the control will be and the slower the response will be. This will eventually lead to a decrease in the driving performance of the car and an increase in fuel consumption and emissions.

At present, there is no report on the throttle-by-wire system that incorporates the extended algorithm of "drink driving monitoring and alarm"
