  • Publication number: 20200031351
    Abstract: A vehicle travel control device controls travel of a vehicle toward a target stop position. Travel state information indicates a travel state of the vehicle and includes vehicle position information indicating positions the vehicle and each wheel. Difference-in-level position information indicates a position of a difference-in-level on a travel path. The vehicle travel control device determines whether the vehicle goes beyond the target stop position when a subject wheel of the vehicle passes the difference-in-level, based on the difference-in-level position information and the vehicle position information. When determining that the vehicle goes beyond the target stop position, the vehicle travel control device changes the target stop position so as to prevent the subject wheel from passing the difference-in-level, or generates a braking force to stop the vehicle before the subject wheel passes the difference-in-level.

  • Patent number: 10486062
    Abstract: In a real space that includes a user, predetermined rules are used to set boundary surfaces of a play area in reference to boundary surfaces of the field of view of an imaging device. If the user gets out of the play area, a warning state determining section determines that there is a need for a warning and superposes a warning image on a display image. A direction in the real space or the state therein, for example, is used to determine whether or not margin areas are to be set between the boundary surfaces of the play area and the boundary surfaces of the field of view, or how wide the margin areas are to be.
