  • Patent number: 11823463
    Abstract: A vehicle periphery monitoring device stores images photographed with a front camera, a rear camera, a left side camera, and a right side camera as a past front image, a past rear image, a past left side image, and a past right side image, respectively. When a vehicle travels while making a turn, the vehicle periphery monitoring device generates an underfloor image indicating a condition of an underfloor of the vehicle using at least one of the past front image and the past rear image and at least one of the past left side image and the past right side image. The vehicle periphery monitoring device displays the generated underfloor image on a display.

  • Patent number: 11731664
    Abstract: A vehicle electronic control device includes a detection device configured to detect a state of an occupant, a first control device, and a second control device. The second control device is configured to refer to a database defining a relationship between the state of the occupant and a first time and to autonomously drive the vehicle at speeds equal to or lower than the maximum allowable speed from a switching time that is the time at which the first control device becomes unable to control the vehicle. The database is set in such a manner that the maximum allowable speed corresponding to a second state of the occupant is lower than the maximum allowable speed corresponding to a first state of the occupant when the first time corresponding to the second state is longer than the first time corresponding to the first state.
