Seat sensor calibration method and system
An air bag calibrator that is used to calibrate a plurality of seat sensors within a seat simultaneously. The calibrator uses controlled pressure contained within an air bladder and an air press cylinder to apply a controlled force across an entire seat surface that actuates all of the seat sensors in a consistent and repeatable manner, a major improvement over existing seat calibration methods. This is accomplished by loading a seat onto the calibrator, recording a baseline seat sensor value for each of the seat sensors, extending the air press cylinder to an extended position and applying a controlled force across the entire seat surface. The air pressure in the air bladder is then increased or decreased to a target pressure for a predetermined time, at which time an actuated seat sensor values for each of the seat sensors is recorded. A PODS controller in contained within the seat that is used for controlling the deployment of air bags in a crash situation is then calibrated as a function of the recorded baseline seat sensor values and the actuated seat sensor values.
