PROBLEM TO BE SOLVED: To provide a vehicular occupant determination device capable of accurately determining a type of an occupant on a vehicle seat even when an acceleration is generated in a vehicle width direction.SOLUTION: A pair of load sensors 2FL and 2RL is disposed at a left end part of a seat cushion. An occupant determination part 61 of an occupant detection ECU 6 determines a type of an occupant of a vehicle seat based on loads W1 and W2 detected by the load sensors 2FL and 2RL. When the acceleration GL of a positive value in the vehicle width direction is a left direction acceleration threshold GLth (+) or more, or the acceleration GL of a negative value is a right direction acceleration threshold GLth (-) or less, a transition prohibition unit 62 causes the state to be in a transition prohibition state in which transition of a determination result on the occupant type is prohibited by the transition prohibition unit 62. When it is detected that a vehicle VE is stopped based on rotation speeds V1, V2, V3, and V4 of the four wheels detected by wheel speed sensors 4FR, 4FL, 4RR, and 4RL, a prohibition release unit 63 causes the state to be in a prohibition release state in which the transition prohibition state is released.SELECTED DRAWING: Figure 2

    【課題】車幅方向に加速度が発生した場合にも、車両シート上における乗員の種別を正確に判定可能な車両用乗員判定装置の提供。【解決手段】シートクッションの左端部には、一対の荷重センサ2FL、2RLが配置されている。乗員検知ECU6の乗員判定部61は、荷重センサ2FL、2RLによって検出された荷重W1、W2に基づき、車両シートの乗員の種別を判定している。遷移禁止部62は、車幅方向の正値の加速度GLが、左方向加速度閾値GLth(+)以上または負値の加速度GLが、右方向加速度閾値GLth(−)以下である場合、遷移禁止部62によって、乗員の種別の判定結果の遷移を禁止する遷移禁止状態にしている。禁止解除部63は、車輪速センサ4FR、4FL、4RR、4RLによって検出された4輪の回転速度V1、V2、V3、V4に基づいて、車両VEが停止していることを検出した場合、遷移禁止状態を解除した禁止解除状態にする。【選択図】図2
