摘要： Systems and methods for controlling the sensing of an occupant in a seating area are provided. The occupant is characterized as one of an adult, child or other category. One characterization change parameter, such as a hysteresis time period or thresholds for characterization, is applied for a first time period. After that time period, the characterization change parameter is changed. For example, if the characterization stays the same for ten seconds, the hysteresis is changed from five to ten seconds. As another example, if the characterization stays the same for one minute, the thresholds associated with that characterization are broadened to decrease the likelihood of a change in characterization. In some systems and methods, a confidence parameter or probability associated with the characterization is used to control the changes to the characterization change parameter. In some systems and methods, the characterizations change parameter in reset in response to one of (a) a no occupant characterization (b) characterizing the occupant as a different one of the at least two categories consecutively for a current hysteresis time period.

摘要： A passenger detection system is provided. The passenger detection system utilizes an oscillation circuit that causes an antenna electrode to emit an electric field that is disrupted by the electrical characteristics of an object placed on the seat. This disruption alters the current and phase of the signal in the antenna electrode. By comparing the current flowing in the antenna electrode and/or the difference between the phase of the signal in the antenna electrode and the oscillation circuit output signal with predetermined threshold values, it is possible to detect the presence of a passenger in a reliable and inexpensive manner. Environmental sensors are used to make the determination more accurate. Humidity, moisture and/or grounding condition are detected and used to alter processing, values or calculations.

摘要： A passenger detection system is provided. A sensor measures capacitance, electric field effects or other characteristic responsive to a load in a seating area. The sensor uses one or more electrodes (e.g., a transmit and receive electrode or one electrode for transmit and one or more electrodes for receive). Other electrodes are connected with different impedances. Measuring by a sensor, but with other electrodes connected with different impedances, may distinguish between an occupant and inanimate objects, may distinguish between characteristics of a passenger (e.g., size, height, weight or position), or may indicate a grounding state of an occupant.

The determination is made with a two layer electrode arrangement, including smaller and larger electrodes. The two layers allow calculation of an amount of compression on the seat. The amount of compression is used to characterize the passenger.

摘要： A vehicle occupancy sensing system provides a mechanism for determining whether a child is present in a vehicle. The sensing system may determine that an occupied front or rear facing child seat is present in an automobile, for example. To that end, the sensing system may employ a reliable electrode sensing system that may be conveniently installed in one or more locations in the vehicle seats. The sensing system thereby helps reduce occurrences of the potentially devastating consequences of unintentionally leaving a child in a vehicle.
