Publication number: 20240066985Abstract: In a detection method of a loading anomaly, relationship between a steering control value of a vehicle and a proper turning radius for the steering control value is constructed as a control map. An actual turning radius of the vehicle is calculated by using a self-location detection function of the vehicle. A difference between the proper turning radius and the actual turning radius is calculated by using the control map. It is determined that a loading anomaly of a cargo loaded on the vehicle has occurred when the difference lies outside a predetermined first reference range.Type: ApplicationFiled: October 25, 2023Publication date: February 29, 2024Applicant: IHI CORPORATIONInventors: Satoru TAGAWA, Yoshiharu KANESHIMA
