The collision sensor is the control signal input device in the airbag system.Its role is to detect the intensity signal of the car collision in the collision sensor when the car collides, and enter the signal into the airbag computer. The airbag computer determines whether the inflatable element is inflated according to the signal of the collision sensor.
Installation location of the collision sensor
Generally, 3 to 4 collision sensors are installed in the SRS airbag system, which is generally installed on the inside of the front -wing plate on both sides of the body.As far as the collision intensity sensor is concerned, the car will install a front collision sensor in the left and front parts of the body, known as the left front collision sensor and the right front collision sensor;Known as a central collision sensor.As far as the protection collision sensor is concerned, it is generally installed with the SRS computer and is installed under the decorative board in the middle of the cab.
Types of collision sensor
The Dashsensor used by the electronic control SRS airbag system can be divided into two categories: collision intensity sensor and protective collision sensor according to the function.The collision intensity sensor is divided into the front collision sensor (including the left front collision sensor, the right front collision sensor) and the central collision sensor according to the installation position.Protective collision sensor is also called a safe collision sensor or detecting the collision sensor.The protective sensor is connected in series with the collision intensity sensor to prevent error in the SRS airbag.
The role of collision sensor
The main role of the collision sensor is to detect or judge the size of the impact signal strength when the car collisions occur. It is based on the size of the impact signal strength to determine when to explode the airbag.The position of the airbag is in the middle of the driver and the steering wheel. A buffer cushion is formed between the driver and the car, which can prevent the driver from hard impact and prevent them from being harmed.The detection vehicle has a large reduction in the inertia when the vehicle collides, and the detection signal is entered into the electronic control device of the airbag system.
Principle of collision sensor
The principle of collision sensor will vary according to the differences in its type.If it is classified according to the structure, it can be divided into electromechanical collision sensors, electronic collision sensors, and mechanical collision sensors.
