Title:
CENTER-OF-MASS VELOCITY DETERMINATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/037130
Kind Code:
A1
Abstract:
A center-of-mass velocity determination method and device. The center-of-mass velocity determination method comprises: acquiring wheel track information, a yaw velocity, and a center-of-mass offset angle which correspond to a target vehicle at a current sampling moment, and a current wheel velocity corresponding to wheels of the target vehicle; according to the current wheel velocity, the wheel track information, the yaw velocity, and the center-of-mass offset angle, obtaining an initial center-of-mass velocity corresponding to the wheels; performing fuzzy reasoning processing on a vehicle velocity measurement value and the initial center-of-mass velocity of the target vehicle to obtain a first confidence coefficient corresponding to the vehicle velocity measurement value and a second confidence coefficient corresponding to the initial center-of-mass velocity; and obtaining a target center-of-mass velocity of the target vehicle according to the vehicle velocity measurement value, the initial center-of-mass velocity, the first confidence coefficient, and the second confidence coefficient.
