Shenzhen EMAR Precision Technology is a professional manufacturer dedicated to the custom processing and mass production of high-precision automotive parts. The company has taken the lead in passing ISO9001, IATF16949 and other quality management certifications. It is one of the few manufacturers in Shenzhen with automotive parts processing qualifications. At present, the company has more than 100 sets of various types of precision processing equipment, providing high-precision parts processing business. Today, let‘s take a look at a rather important part of automotive parts - automotive sensors. What is the role they play in the large frame of the car?

　　A car sensor is a device used for detection, capable of sensing the measured information and converting the sensed information into electrical signals or other required forms to output information according to certain rules, in order to meet the requirements of information transmission, processing, display and storage, and recording and control. For example, the oxygen sensor on the Sanhua catalytic converter is used to detect the concentration of oxygen in the discharge period and send feedback information to the ECU. This process is to convert the oxygen concentration into an electrical signal.

　　The current car is equipped with a large number of sensors, especially the development of smart cars, which is inseparable from the powerful functions of sensors, which are used to measure the car‘s instrument and indicator system and control other functions of the car, such as brakes, emergency lights, wipers, near and far light, etc., can be realized by sensors.

　　Automotive sensors can realize various automatic controls of automobiles

　　The automotive electronic control system consists of sensors, electronic controllers (ECUs) and actuators. In the automotive electronic control system, the function of sensors is to convert the relevant parameters of the controlled object into corresponding electrical signals and send them to the controller. The controller analyzes and judges the working conditions and states of the controlled object according to the signals of the relevant sensors, and outputs the control signal to realize automatic control through the actuator. The electronic control system is divided into engine electronic control system, chassis electronic control system and body electronic control system.

　　The automotive electronic control system is composed of sensors, electronic controllers, and actuators. In the automotive electronic control system, the function of the sensor is to convert the relevant parameters of the controlled object into the corresponding electrical signal, and transmit it to the controller. The controller analyzes and judges the working conditions and status of the controlled object according to the relevant signals transmitted, outputs the control signal, and realizes the automatic control of the actuator. The electronic control system is divided into three types: the engine electronic control system and the chassis electronic control system. The main functions are:

　　1. The engine control system mainly includes fuel injection control, engine idling control, ignition control, and carbon tank ventilation control.

　　2. The chassis electronic control system includes anti-lock braking control system (ABS), anti-skid rotation electronic control system (ASR), automatic transmission electronic control system, suspension electronic control system, cruise control system, etc.

　　3. The body electronic control system mainly includes airbag control system, automatic air conditioning control system, as well as electronic instrumentation and anti-theft control system.

　　The automotive control system can measure the working state and limit parameters of automotive components

　　In an automotive instrumentation control system, the function of various instrumentation automotive sensors is to convert the temperature of the engine, the speed of the engine, the pressure of the oil, the speed of the transmission output shaft, the height of the fuel tank oil level and other physical parameters into corresponding voltages, currents, and electrical pulses, and drive the corresponding instrument actions to display the corresponding measured parameters. When the measured value reaches the preset limit value, the indicator light will be alerted.

　　The current automotive industry is rapidly developing like intelligent and unmanned, and countries are also competing to develop driverless cars. Sensors play a particularly important role. This type of component that occupies an important position has a very high test for the process. Shenzhen EMAR Precision Technology has the processing qualification of automotive parts, and we have many years of processing experience in aluminum parts that are often used in the automotive field. Secondly, it also includes various types of stainless steel, alloy steel, copper, Pom Saigang, and other materials. The company strictly follows the IATF16949 quality management certification and has the industry‘s leading processing technology and technical team to provide you with a full range of product solutions.
