Embodiment Construction

[0015] The present invention will be further described below in conjunction with drawings and embodiments.

[0016] like figure 1 , the control system adopts the structure of field bus type collection and distribution system FDCS (Field Distributed Control System), which is composed of sensors, actuators, controller intelligent nodes and CAN field control network. Multiple intelligent nodes independently complete data acquisition, system setting, operation control, etc., and exchange various data and management control information among intelligent nodes through the CAN field bus.

[0017] The control system consists of an accelerator pedal position sensor and an electronic throttle body. The throttle body includes three parts: an actuator, a throttle valve and a throttle position sensor, which are packaged as one. The actuator consists of a DC motor and associated transmission components. The accelerator pedal is a high-precision linear potentiometer, which is used as a sen...

Abstract

The invention discloses an intelligent node based automobile electronic throttle valve control system which adopts a FDCS (filed distributed control system). The intelligent node based automobile electronic throttle valve control system consists of a sensor, a performer, a controller intelligent node and a CAN (Control Area Network), wherein the control system is used for applying a CAN bus to anintelligent sensor, so that a signal obtained by the sensor can be reliably and accurately transmitted at a high speed in real time through the bus, each automobile computer control unit can share allinformation and resources through the CAN bus, and achieves the purposes of simplifying wiring, reducing quantity of sensors, preventing control function repetition, reducing cost, and matching and coordinating each control system better.

Description

Technical field [0001] The invention relates to an automotive electronic throttle control system based on an intelligent node, which is suitable for the mechanical field. Background technique [0002] With the advancement and development of science and technology, the requirements for vehicle driving performance and safety and comfort have been greatly improved, which has gradually increased the number of electronic control units on the vehicle, but the electronic control units on the vehicle (such as various switches, actuators, sensors, etc.) etc.) are still implemented with the traditional wiring harness, which makes the wiring harness in the car too much and the wiring is complicated, which causes serious electromagnetic interference and reduces the reliability of the system. In high-end cars, electronic components and their systems account for more than 20% of the price of a complete vehicle, and there is an increasing trend. In this case, the electronic control circui...
