Automotive sensors can be the external environment of a variety of physical signals and parameters such as speed, temperature, engine operating conditions, into electrical signals, and the central processor to provide the necessary information. Automotive sensor as an important source of automotive electronic Sensor control system, automotive electronic control system is a key component, but also automotive semiconductor technology research one of the core content. The key to evaluating the level of an electronic control system for a modern limousine is the number and level of sensors used.
Automotive sensors include pressure, level, flow, position, height, distance, speed, speed, torque, acceleration, temperature, image, intelligence and other sensors. Modern automotive electronics from the application of electronic components to the structure of the electronic system has entered a new stage of essential improvement, one of the most representative of the core device is the sensor. With the development of automotive Fuel Rail Pressure Sensor semiconductor technology, the car will become more and more humane, and even achieve all the features of the electrification, more comfortable operation, convenient, environmentally friendly, car safety, environmental protection, entertainment and other needs to promote
There are more and more sensors on the car. A variety of sensors have been deeply integrated into the various functional systems of the vehicle, including engine management system (EMS), chassis and transmission systems, safety systems, body electronics systems, air conditioning systems and so on. As the requirements of environmental protection and fuel consumption regulations continue to make the engine more and more complex, the engine electronic control system performance will Temperature Sensor be increased accordingly, which requires continuous improvement of the amount and accuracy of the sensor in the automotive engine electronic control system, the sensor is very important The status.
With the development of automotive semiconductors, multifunctional, high precision, high sensitivity, intuitive electronic digital display and image display instruments are constantly used in automobiles. Sensors are the most important semiconductor devices in automotive electronic instrumentation. Most electronic instrumentation is based on the sensor. The sensor device changes its resistance value according to the state change of the monitored object and is indicated by the instrument. The most commonly used in the dashboard is the speed odometer, a lot of car meters have been using electronic speedometer. The oil pressure gauge, water temperature gauge ABS Sensor and fuel gauge on the instrument panel are instruments that are directly related to the engine's work. Each of them has a corresponding sensor that reflects the information of the object on the meter.
The future development of automotive sensor technology, not only the development of the sensor itself, but also pay more attention to the sensor interchangeability, durability, reliability of the development. Sensor technology is moving in the direction of miniaturization, versatility, intelligence and higher reliability. Because MEMS-based micro-sensors, in reducing the cost of automotive electronic systems and improve its performance advantages, they have begun to gradually replace the traditional electromechanical technology based sensors.
The main growth areas of automotive sensors in the coming years, sensors for biometric measurements to improve vehicle safety and comfort; accelerometers for vehicle dynamics control and airbags; for transmission, braking, cooling, fuel, etc. Pressure sensors for vehicle dynamics, rollover and GPS backup; position sensors for wheel speed and camshaft, crankshaft, pedal position sensitivity; humidity sensor for vehicle environment monitoring; Distance sensors for obstacle detection Throttle Position Sensor and collision avoidance; MEMS micro-pressure sensors for tire pressure monitoring systems, such as Freescale and Infineon, are pushing their own tire pressure sensor products to market.
In short, with high sensitivity, impact resistance, to adapt to a variety of environments, high reliability, high security and other features of the sensor, the global sensor market demand for hot products.
