What is the concept and main function of the collision sensor?
Collision sensor is a device in the airbag system, which can detect the intensity of the car collision, and simultaneously send a signal, and then input the signal into the airbag system, the microcomputer in the airbag can be based on the input signal To determine whether it is necessary to detonate the inflatable element. This article mainly introduces the collision sensor and its main function for everyone.
Introduction to collision sensors
The English abbreviation of airbag is SRS, and its full English name is SupplementalRestraint Systems. The airbag is the most common safety device on a car. The position of the airbag is between the driver and the steering wheel. A cushioned cushion is formed between the driver and the car to prevent the driver from hard impact and prevent them. Hurt. The airbag system generally consists of several parts: collision sensor, airbag, igniter, monitoring device, ECU electronic control unit, gas generator, reserve power supply, etc.
Collision sensors can be divided into collision intensity sensors and collision protection sensors if they are classified according to the functions of the sensors. The collision intensity sensor is mainly used to detect the degree of damage to the car by the collision. The collision intensity sensor can also be classified according to its installation position, which can be divided into a left front collision sensor, a right front collision sensor and a center collision sensor. The collision protection sensor is mainly used to prevent the airbag from inflating due to misunderstanding or sensor detection error. Therefore, the collision protection sensor is also called a safety collision sensor or a collision detection sensor.
The main role of the collision sensor
The collision sensor can detect the inertia of the car when the car has a great deceleration when a collision occurs
force, and then the collision sensor can input the detected signal strength into the electronic control device. The main function of the collision sensor is to detect or determine the magnitude of the impact signal strength when the car collides, according to the magnitude of the impact signal strength to determine when to ignite the airbag. The position of the airbag is between the driver and the steering wheel, and a cushion is formed between the driver and the car to prevent the driver from hard impact and prevent them from being injured. Detects the inertial force at the maximum deceleration when the car collides, and inputs the detection signal to the electronic control device of the airbag system.
