PASSENGER DETECTION SYSTEM AND METHOD |
摘要 |
A passenger detection system is provided. The passenger detection system utilizes an oscillation circuit (10) that causes an antenna electrode (E1) to emit an electric field that is disrupted by the electrical characteristics of an object placed on the seat (1). This disruption alters the current and phase of the signal in the antenna electrode (E1). By comparing the current flowing in the antenna electrode (E1) and the difference between the phase of the signal in the antenna electrode (E1) and the oscillation circuit (10) output signal with predetermined threshold values, it is possib le to detect the presence of a passenger in a reliable and inexpensive manner. |
