What is the car side impact sensor
The automobile side impact sensor is an important component of the airbag system. Its main function is to detect the intensity signal of the collision when the side impact occurs, and input the signal to the airbag computer, so as to determine whether the inflator needs to be detonated to inflate the airbag. The collision sensor usually adopts the inertial mechanical switch structure, and its working state depends on the acceleration of the car during the collision .
Installation position and function
Automotive side impact sensors are usually installed in the front and middle of the body, such as the inside of the fender panels on both sides of the body, under the headlight brackets, and on both sides of the engine radiator brackets. The positioning of these sensors ensures that in the event of a side impact, the collision signal is detected in time and transmitted to the airbag computer .
Working principle
When the car is in a side impact, the collision sensor detects the inertial force under the extreme deceleration and feeds these detection signals into the electronic control device of the airbag system. The airbag computer uses these signals to determine whether it needs to detonate the inflator to inflate the airbag.
The main function of the vehicle side impact sensor is to detect the acceleration or deceleration of the vehicle when the side impact occurs, so as to judge the intensity of the collision, and input the signal to the electronic control device of the airbag system . When the sensor detects a crash intensity that exceeds the set value, it sends out a signal, based on which the airbag system decides whether to detonate the inflator element, inflating the airbag to protect the occupants .
How the side impact sensor works
The side impact sensor usually adopts inertial mechanical switch structure, and its working state depends on the inertial force generated when the car crashes. When the car is involved in a side impact, the sensors detect the inertial force under the extreme deceleration and feed this signal to the electronic controls of the airbag system. The sensor can sense the acceleration or deceleration at the time of collision, so as to judge the severity of the collision .
Installation position
Side impact sensors are generally installed on the sides of the body, such as the inside of the fender panels on both sides of the body, under the headlight bracket, and on both sides of the engine radiator bracket. Some cars also have trigger crash sensors built into the airbag computer to ensure a timely response in the event of a crash.
Historical background and technological development
With the continuous development of automotive safety technology, side impact sensors are also improving. Modern cars are often equipped with multiple trigger collision sensors to improve the reliability and responsiveness of the system. Some advanced cars even integrate the sensor directly into the airbag computer, further improving the overall performance and safety of the system .
