Abstract:
1. An occupant sensor device disposed in a vehicle comprising: a sensor body disposed in a base part of a seat, wherein the sensor body is divided into at least two parts along at least one of two axes, such that a first sensor part of the sensor body is positioned in front of a second sensor part; and an occupant detector detecting an occupant position posture and an occupant type of an occupant seated on the seat based on a capacitance between the sensor body and a vehicle body, wherein the occupant detector detects the occupant position posture and the occupant type based on a first capacitance, a second capacitance, and a total capacitance, which is a total of the first capacitance and the second capacitance, the first capacitance is a capacitance between the first sensor part and the vehicle body, and the second capacitance is a capacitance between the second sensor part and the vehicle body, the sensor body is divided into four parts, such that the first sensor part has a first-right sensor part and a first-left sensor part, the second sensor part has a second-right sensor part and a second-left sensor part, which are respectively behind the first-right sensor part and the first-left sensor part, the first-right sensor part and the second-right sensor part form a right sensor part of the sensor body and the first-left sensor part and the second-left sensor part form a left sensor part of the sensor body, and the occupant detector detects the occupant position posture and the occupant type based on a right-side capacitance, a left-side capacitance, and the total capacitance, the right-side capacitance is a capacitance between the right sensor part and the vehicle body, and the left-side capacitance is a capacitance between the left sensor part and the vehicle body.
