PROBLEM TO BE SOLVED: To provide a method and apparatus for deciding a float angle of a vehicle with high precision, where a yaw rate sensor decides the yaw rate of a vehicle (automobile). SOLUTION: In a method for deciding a float angle (β) of a vehicle, a yaw rate (ωgier) of a vehicle is acquired with a yaw rate sensor (101). The direction of a velocity (v) at the gravitational center of the vehicle is acquired by frequency-analyzing the signal received by an onboard GPS receiver. The float angle (β) is acquired as a function of at least the yaw rate (ωgier) and the direction of the velocity (v) of the vehicle (112). COPYRIGHT: (C)2004,JPO |
