Abstract:
1. A vehicular behavior determination device which determines a behavior of a vehicle, comprising: a first arithmetic processor, which determines a parameter representing the behavior of the vehicle; a second arithmetic processor, which calculates a posture vector representing a posture of the vehicle in a global coordinate system on the basis of a determination result determined by the first arithmetic processor; and a third arithmetic processor, which calculates an angular velocity vector representing an angular velocity of the vehicle around each of 3 orthogonal axes in a vehicular coordinate system on the basis of a temporal variation mode of the posture vector calculated by the second arithmetic processor; wherein the second arithmetic processor calculates an i the third arithmetic processor obtains a rotational main axis vector which represents a direction of a rotational main axis in the global coordinate system by combining 3 rotational axis vectors for making a previous i
