Automatic detection technology has been widely used in industrial and agricultural production, national defense construction, transportation, medical and health, environmental protection, scientific research and people's daily life, and plays an increasingly important role in national economic development and social progress. An essential and important basic technology. This paper describes the detection object and detection principle of automotive sensors, and introduces the specific application of the relevant sensors in the anti-lock braking system and airbag system.

1 Application of automatic detection technology in automobile safety system
1.1 Anti-lock brake system (ABS)
With the implementation of the new law, traffic safety has received more and more attention from all parties. At the same time, the state has also promulgated a series of mandatory regulations and national standards to impose strict restrictions on vehicle safety performance. The most basic active safety device for car safety equipment - ABS anti-wheel lock mechanism has been forced to install on the prescribed car. The world's first anti-lock Brake System (ABS) was introduced in 1950 and was first used in aircraft in the aerospace sector. It has only been researched in automotive applications since 1968, one of the greatest achievements of automotive technology since the late 1980s.
ABS is an automobile safety control system with the advantages of anti-skid and anti-locking. It not only has the braking function of the ordinary braking system, but also prevents the wheel from being locked, so that the car can still turn under the braking state to ensure the car's The stability of the braking direction prevents the occurrence of side slip and deviation. It is the most advanced braking device with the best braking effect in the automotive field.
ABS consists of three parts: sensor, brake pressure regulator and electronic controller. The electronic controller is also called the Electronic Control Unit (ECU). The sensor for testing the number of revolutions of the wheel and the controller for adjusting the number of revolutions are essential components for achieving the control target, which is an important theoretical basis for the development of the ABS system for vehicles. The working principle of the anti-lock braking system of the car is shown in Figure 1.
