The sensor on the automobile is the information source of the automobile electronic control system, which is the key component of the automobile electronic control system and the core of the research of the automobile electronic technology field. Automotive sensors for real-time, accurate measurement and control of temperature, pressure, position, speed, acceleration and vibration. The core of the sensor on the car, the engine control sensor and several sensors.
The engine management system uses a variety of sensors, is the core of the entire automotive sensor, many types, including temperature sensors, pressure sensors, position and speed sensors, flow sensors, gas concentration sensors and knock sensors. These sensors will be the engine suction air volume, cooling water temperature, engine speed and acceleration and deceleration and other conditions into Suction Control Valve electrical signals into the controller, the controller will compare these information and storage information, accurate calculation of the output control signal. The engine management system not only can precisely control the fuel supply to replace the traditional carburetor, but also can control the ignition advance angle and idle air flow, etc., greatly improve the engine performance.
Today, the development of the automotive industry has led to more sensors on the car, the characteristics of the sensor also makes the car become more intelligent, such as tire pressure monitoring system is installed in each wheel frame micro-pressure sensor to measure the pressure, and through The wireless transmitter transmits the information to the front of the drive. When the tire pressure is too low, the system will automatically send an alarm to remind the driver to deal with in a timely manner. This will not only ensure that the car in the driving safety, but also to protect the tread, to extend tire life and achieve fuel-saving purposes. The tire pressure monitoring sensor is capable of accurately measuring the air pressure and temperature of the tire and transmitting the information to the receiver mounted in the vehicle via wireless signals. Today, air pollution in the car poses a new threat to the health of car owners, mainly from carbon monoxide. With the rapid increase in the number of car owners, the car's air quality began Fuel Rail Pressure Sensor to receive attention. Carbon monoxide sensor with high sensitivity, strong anti-interference, low power consumption, specifically used to ensure the safety of air quality inside the car. At the same time the application is simple, long life, you can monitor the air quality in a timely manner. Carbon monoxide sensor is divided into internal and external air conditioning inside and outside the cycle of automatic switching systems and cars, passenger cars with carbon monoxide alarm.
Vehicle anti-theft tilt sensor, the angle sensor using 2-axis acceleration sensor, can be found in the theft of vehicles when the vehicle is caused by the tilt, and issued an alarm, the acceleration sensor for the electrostatic capacity type. Angle sensor market demand will become increasingly strong. The new thick film piezoresistive non-contact vehicle oil pressure sensor, the use of thick film force sensitive technology and surface micro-assembly technology to produce, monitor the engine oil pressure, oil can achieve low pressure alarm. Has been through the bench test, type test and 6000 times the durability test, can directly replace the existing bimetallic slip YG2221G oil pressure sensor. Compared with Fuel Rail Pressure Sensor the existing slide-type hydraulic sensor, with high precision, no mechanical parts contacts, high reliability, long life, corrosion resistance, with the digital instrumentation, low cost, high cost performance. It is easy to see the application of acceleration sensors on the car will be the future of the automotive industry's biggest trend.
