The role of sensors in automobile automatic control is becoming increasingly important and widely applied. In this issue, we will introduce various types of sensors that may be used in cars and their functions. 1 Air Flow Sensor The function of the air flow sensor is to convert the amount of air inhaled by the … Read more
The Development of Automotive Electronic Control Technology The rapid development of automotive electronic control technology mainly depends on three factors: first, the rapid advancement of transistor technology, large-scale integrated circuit technology, computer technology, and network technology has continuously reduced costs and enhanced control functions, providing favorable conditions for the development of automotive electronic control technology; … Read more
1. The electronic control unit (ECU) mainly consists of input circuits, A/D converters, computers, and output circuits.(√) 11 2. The electronically controlled gasoline injection system utilizes negative pressure generated in the throat of the throttle above the throttle valve during air flow to draw out gasoline, which is then atomized and delivered to the engine. … Read more
Follow 【指尖维修】 for fresh insights on motorcycle maintenance and repair! Author: 行思止随 Yesterday, we discussed how fuel-injected motorcycles no longer require ignition coils, as their functions have been replaced by the ECU, and we listed the four main functions of the ECU. Today, we will discuss the internal structure and workflow of the ECU. The … Read more
TechGear The ECU is the core of the electronic control system. It is essentially a microcomputer or microcontroller that receives signals from sensors on one hand, processes this information, and sends corresponding instructions to control the actions of actuators on the other hand. Sensors are components that perceive information, responsible for providing the ECU with … Read more
On August 26, FANUC Industrial Robot Technology Training Class What is a Robot Control System? If humans only had senses and muscles, their limbs would still be unable to move. This is partly because there are no organs to receive and process signals from the senses, and partly because there are no organs to send … Read more
If humans only had senses and muscles, their limbs could not move. This is because, on one hand, the signals from the senses have no organs to receive and process them, and on the other hand, there are no organs to emit nerve signals that drive the muscles to contract or relax. Similarly, if a … Read more
