What does SRS mean in cars?

[NoahLynn]

Car SRS refers to the airbag, which is a passive safety protection system. The following is an introduction to the airbag system: 1. Composition: It mainly consists of an airbag sensor, a collision airbag, and an electronic control device. The driver-side collision airbag is installed in the steering wheel; the passenger-side collision airbag is generally installed on the dashboard. The airbag sensors are installed on the left, right, and center of the cabin partition; the central airbag sensor and the airbag system are installed together with the electronic control device. 2. Principle: When a collision occurs while the car is in motion, the airbag sensor first receives the impact signal. Once the impact reaches the specified intensity, the sensor activates and sends a signal to the electronic controller. Upon receiving the signal, the electronic controller compares it with its stored data. If the conditions for airbag deployment are met, the driver circuit sends a start signal to the gas generator in the airbag assembly.
