PROBLEM TO BE SOLVED: To provide a vehicle state determination device capable of determining traction on a front wheel drive vehicle, or four wheel drive vehicle.SOLUTION: A vehicle state determination device comprises: a vertical load calculation unit 12 for calculating a vertical load, based on control time and stroke amount in a vehicle height adjustment control time; a total weight calculation unit 13 for calculating a total weight, based on an output shaft torque of a transmission and vehicle body acceleration; and a traction state determination unit 14 for determining that the vehicle is in a traction state, when the total weight is larger than a value of the vertical load/gravity acceleration+hysteresis.SELECTED DRAWING: Figure 1
【課題】前輪駆動車や四輪駆動車における牽引判定が可能な車両状態判定装置を提供すること。【解決手段】車両状態判定装置は、車高調整制御時の制御時間およびストローク量に基づいて垂直荷重を算出する垂直荷重算出部12と、トランスミッションの出力軸トルクおよび車体加速度に基づいて総重量を算出する総重量算出部13と、総重量が、垂直荷重/重力加速度+ヒステリシスの値よりも大きい場合、車両が牽引状態であると判定する牽引状態判定部14と、を備えることを特徴とする。【選択図】図1
