Seat sensor makes airbags smarter.
Smart fabric sensor technology specialist BeBop Sensors has announced the automotive Occupant Classification System (OCS), featuring embedded car seat sensors with intelligent car occupant sensing technology for safer airbag deployment. BeBop's high-resolution OCS sensing system provides the detail required to distinguish subtle details and changes to an occupant's position and movements in real time.
Whereas current systems only estimate the weight of a passenger in order to deploy or disable airbags when determining if a child or infant car seat is placed on the front passenger seat, the Bebop smart fabric sensor OCS continuously takes full seat pressure images in real-time; it detects pressure information and movement from the entire seat for all aspects of physical contact between the occupant and the seat, including leaning forward or back, left or right, crossing legs, detecting the rigid bottom of a child's booster seat and the occupant's size and weight.
In a system purely based on weight, a bag of groceries and a small child look the same, since they rely on a combination of bladders, hoses and pressure sensors to estimate the weight on the seat. Armed with only weight information, very little intelligence is used to determine airbag deployment, resulting in numerous malfunctions. Due to the increasing failure rates in current systems and the resulting recalls, car manufacturers are looking for more intelligent and dependable OCS solutions. A recent example was the recall of 3.5 million Nissan vehicles because of airbag problems.
"Anyone trying to determine a person's position, size, and seating attitude using only weight is making a faster horse. That technology is now obsolete. You can tell more about a person through a picture than a scale," said BeBop Founder & CEO Keith McMillen.
At 1mm, BeBop's flexible, waterproof OCS sensor system is thin enough to be placed under the seat cover. The fabric-based sensors are substantially lighter than any other liquid-based OCS, ensuring minimal weight is added to the seat construction. BeBop's OCS sensors also have no moving parts, further increasing reliability. The sensors are automotive grade (environmental specs and durability) and can be custom designed for any seat in the front or back row.
BeBop Sensors is working now with OEMs in the automotive industry to develop and deploy custom fabric sensors for OCS/safety applications, autonomous vehicles, comfort enhancement and soft-switch control interfaces.
