PROBLEM TO BE SOLVED: To provide a passenger determination device capable of preventing erroneous passenger determination upon considering acceleration sensor errors.SOLUTION: A passenger determination device comprises: weight sensors 10 and 20 detecting a weight on a seat of a vehicle; a lateral acceleration sensor 30 detecting a lateral acceleration of the vehicle; and a processing unit 40 processing passenger determination. The processing unit 40 calculates a lateral acceleration difference that is an absolute value of the difference between a first acceleration at which the weight passes through a first load threshold and a second acceleration at which the weight passes through a second load threshold, performs the passenger determination based on a passenger determination threshold if the lateral acceleration difference is smaller than a lateral acceleration difference threshold, and does not perform the passenger determination if the lateral acceleration difference is greater than the lateral acceleration difference threshold.

    【課題】加速度センサの誤差を考慮した上で、乗員を誤って判定することを防止する乗員判定装置を提供する。【解決手段】乗員判定装置は、車両のシート上の重量を検出する重量センサ10、20と、車両の横加速度を検出する横加速度センサ30と、乗員判定の処理をする処理ユニット40とを備える。処理ユニット40は、重量が第1荷重閾値を通過した場合の第1横加速度と、重量が第2荷重閾値を通過した場合の第2横加速度との差分の絶対値である横加速度差を算出し、横加速度差が横加速度差閾値より小さい場合、乗員判定閾値に基づいて乗員判定を行ない、横加速度差が横加速度差閾値より大きい場合、乗員判定を行わない。【選択図】図1
