Abstract
An apparatus for detecting seated condition detects whether a passenger is seated on a seat and the location of the passenger if seated. In the apparatus for detecting seated condition, antenna electrodes are provided in the inside the seat so that the electric field generates between the ground and the antenna electrodes. A detecting unit detects a first out put of the electric field in a case that a passenger is not seated and a second output of the electric field in a case that a passenger is seated. A data processing unit corrects the second output based on the first output. Accordingly, the seated condition whether the passenger is seated can accurately be detected.
