Electronic throttle controller of electronically controlled engine

Abstract

The invention relates to an electronic throttle controller of an electronically controlled engine. The electronic throttle controller is characterized by comprising a fault diagnosis module, an engine condition identification module and a servo control module, wherein the fault diagnosis module can be used for counting according to output voltages of two throttle position sensors, output voltages of two pedal position sensors, working voltages of the sensors, a working current of a throttle motor, a called count value of the engine condition identification module and a called count value of the servo control module, which are collected, so as to carry out sensor diagnosis, actuator diagnosis and algorithmic dispatching abnormity diagnosis; the engine condition identification module is used for identifying and calculating the current operation condition of the engine according to the opening, the water temperature and the rotating speed of engine pedals, air conditioner on-off information and power-on information, which are collected by the sensors; the servo control module is used for analyzing and calculating the opening of a destination throttle according to fault codes in the fault diagnosis module and the engine operation condition in the engine condition identification module as well as the opening, the water temperature, the rotating speed and the air conditioner on-off information, which are collected by the sensors, and finally the servo control module calculates and obtains a PWM control signal to output.

Description

technical field [0001] The invention relates to a control capacity of an electronically controlled engine, in particular to an electronic throttle controller of an electronically controlled engine. Background technique [0002] The engine electronic throttle uses a set of sensors and actuators to replace the traditional mechanical transmission mechanism between the accelerator pedal and the engine throttle. The ETC (Electronic Throttle Controller) controller is a flexible control system, which drives the throttle valve through the motor on the throttle body, and under the control of the engine electronic control unit ECU (Electronic Controller Unit), the throttle opening can be realized. fast and precise control. ETC can realize the learning of the minimum opening of the engine to reduce fuel consumption, and optimize the emission level and driving performance of the engine. [0003] At present, the existing ETC controller has the following defects: the ETC controller lack...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing ETC controller has the following defects: the ETC controller lacks a fault self-diagnosis module, and does not perform real-time diagnosis on the sensor, motor part and software control module of the electronic throttle, so that it cannot cope with the convenience of sudden throttle failure Solution: The current electronic throttle opening is obtained based on a specific test to look up the table, lacking the diversity of the surrounding environment, the electronic throttle cannot self-study to achieve the minimum opening
