Publication number: 20230373497Abstract: A wheel load estimation device includes an obtaining unit obtaining angular velocities and angular accelerations of a rigid body including an element, accelerations of the rigid body in a front-rear direction and in a lateral direction, a weight of the element, and a position including a height of the element. The element fluctuates a center of gravity of the rigid body. A center-of-gravity inertia value calculation unit calculates information relevant to the center of gravity of the rigid body and an inertia value. A wheel load variation calculation unit calculates variation amounts of wheel loads that each act on a corresponding one of a plurality of wheels supporting the rigid body. A wheel load estimation unit estimates the wheel loads.Type: ApplicationFiled: July 28, 2021Publication date: November 23, 2023Applicant: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Tatsuya HATTORI, Hiroyuki YAMAGUCHI, Daiki MORI, Yoshikazu HATTORI, Noriyoshi SUZUKI
