Linear ultrasound transducer array for an automotive occupancy sensor system |
摘要 |
An improved automotive occupancy sensor (AOS) system comprising a linear or spaced array of ultrasound (US) transducers mounted adjacent the headliner of a vehicle to direct an array of US beams to define a preselected occupancy zone adjacent a seat of the vehicle. The AOS electronics may be integrally packaged with the transducer array and flush mounted within the headliner. The array permits occupancy state to be determined by a AOS classification algorithm and method using only or US echo range data, thereby reducing the cost and complexity of the system, improving speed and simplifying calibration. |
