To provide a vehicle state detection device which can detect a spin behavior without requiring a detection value of a steering angle sensor.SOLUTION: A vehicle state detection device 10 acquires information about a vehicle body speed Vx, lateral acceleration Ay and a yaw rate Yr of a vehicle from a sensor mounted on the vehicle. The vehicle state detection device calculates an actual lateral speed differential value dVy indicating an actual lateral speed differential value of the vehicle and a standard lateral speed differential value dVyStd indicating a lateral speed differential value of a vehicle becoming the standard from the acquired information about the vehicle body speed Vx, lateral acceleration Ay and raw rate Yr. The vehicle state detection device determines that the vehicle performs a spin behavior when a difference dVyError obtained by subtracting the standard lateral speed differential value dVyStd from the actual lateral speed differential value dVy exceeds a prescribed threshold.SELECTED DRAWING: Figure 3
【課題】舵角センサの検出値を必要とせずにスピン挙動を検出することが可能な車両状態検出装置を提供する。【解決手段】車両状態検出装置10は、車両に搭載されるセンサから車両の車体速Vx、横加速度Ay及びヨーレートYrの情報を取得する。取得した車体速Vx、横加速度Ay及びヨーレートYrの情報から、車両の実際の横速度微分値を示す実横速度微分値dVyと、規範となる車両の横速度微分値を示す規範横速度微分値dVyStdを算出する。実横速度微分値dVyから規範横速度微分値dVyStdを引いた差分dVyErrorが所定の閾値を超えた場合に、車両がスピン挙動をしていると判定する。【選択図】図3
