Smart controller of electronic air throttle

Abstract

The electronic intelligent controller of the throttle, features for the sensor installed on the decelerator which connected with the throttle, the sensor collects the position signal of the throttle, through linear isolated circuit and CAN bus isolated circuit controlld by CAN bus, the signal enters the central controller, the central controller calculate the output PWM signal by input CAN signal or accelerate pedal signal, through high speed isolated driving circuit, the signal to sent to the H bridge circuit, which controls the driving motor running, the central controller can receive the CAN signal from other controller as well as directly from the accelerate pedal signal to achieve the accurate control.

Description

Technical field: [0001] The invention relates to the field of automobile control, in particular to an intelligent controller for accurately controlling the opening of an automobile electronic throttle. Background technique: [0002] The car throttle is mainly used to control the flow of combustible mixture, so as to change the speed and power of the engine to meet the needs of the car. At present, most domestic automobiles use traditional mechanical throttle valves, that is, the throttle valve control mechanism works through a cable (soft steel wire) or a pull rod, one end of which is connected to the accelerator pedal (accelerator pedal), and the other end is connected to the throttle linkage plate to work. This kind of mechanical throttle is completely controlled by the car driver, which is greatly affected by personal subjective factors. Throttle valve opening cannot fully reflect the car's current demand for energy. [0003] The emergence of functional requirements suc...
