Automotive Seat Occupancy Sensors (OCS) Product Description
Product Overview
As automotive safety technology continues to innovate, automotive seat occupancy sensors (OCS) are becoming more and more important as a key component in enhancing the passive safety performance of automobiles, and Jasper, as an outstanding manufacturer of automotive seat occupancy sensors, provides critical data for automotive safety systems to safeguard drivers and passengers in all aspects of transportation.
Working Principle
- Pressure Sensing: The high-performance pressure sensor inside the seat cushion can convert the pressure change generated by human body pressure or gravity into an electrical signal. Like capacitive through the capacitance value, resistive through the resistance value of the change in the determination of pressure, in order to determine whether the seat is occupied or not.
- Capacitive Sensor: Detects the change in capacitance value triggered by the change in electric field on the seat surface when a person approaches or touches the seat. Its high sensitivity can sense the passenger's approach in advance and provide support for the early response of vehicle-related functions.
- Infrared Sensor: Actively emits infrared rays, which are reflected back when they meet the human body. The sensor receives the reflected signal and converts it into an electrical signal to determine whether the seat is occupied. Thanks to this principle of operation, infrared sensors can reliably and efficiently detect seat occupancy.
- Ultrasonic Sensing: Based on the principle of ultrasonic propagation and reflection, it determines the position of the object by measuring the time and speed of the reflected wave, and the multiple sensor arrays can realize 360-degree detection.
Product Advantages
- Accurate Detection: Integrating multiple technologies, it accurately recognizes seat occupancy and passenger weight with minimal error.
- Rapid Response: Millisecond response, can instantly transfer the seat status information to the safety system.
- Stable and Reliable: It has been tested in extreme environments such as high and low temperatures, vibration, waterproof and dustproof, and can be adapted to a variety of harsh driving environments.
- Strong Compatibility: It can be seamlessly connected with most of the automobile safety systems on the market, and is easy to install.
Application Scenarios
- Airbag Control: In case of a collision, adjust the airbag ejection force according to the weight of the passenger monitored by OCS to ensure safety.
- Seat Belt Reminder: Detecting passengers not fastening seat belts, triggering timely reminder to avoid ineffective prompts.
- Child Seat Protection: Works with ISOFIX device to recognize the state of child seat use and adjust the safety system settings.
- Pre-Tensioned Seat Belt Adjustment: Optimize the pre-tensioning strength according to the passenger's weight and sitting position, and collaborate with other safety devices for protection.
