  • Publication number: 20240066985
    Abstract: 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.

  • Patent number: 7005848
    Abstract: A position detecting sensor includes a magnet, a magnetic detecting element, and a yoke adjacent to or near the magnet. A detected member is positioned at one side of the position detecting sensor so as to be adjacent to or away from the position detecting sensor. The magnet is oriented to generate a magnetic line of flux which flows in a direction complying with an extending direction of the detected member. The magnetic detecting element is positioned in an area in which a magnetic flux density generated by the magnet is relatively low when the detected member is positioned away from the position detecting sensor and a magnetic flux density is relatively high when the detected member is positioned adjacent to the position detecting sensor.
