An alarm device includes a unit determining whether state of driver is inappropriate state to generate vibration of predetermined intensity in seat belt based on in-vehicle sensor signal, a unit determining whether situation requiring notification of predetermined warning to the driver occurs, based on out-of-vehicle sensor signal, behavior sensor signal, in-vehicle sensor signal, and current location of vehicle, and a unit notifying driver of predetermined warning by generating vibration of predetermined intensity in seat belt when situation requiring notification of predetermined warning occurs and when state of driver is not an inappropriate one, notifying driver of predetermined warning by generating vibration of intensity weaker than predetermined intensity in seat belt or using notification unit other than seat belt or stopping notification of predetermined warning, when situation requiring notification of predetermined warning occurs and when state of driver is an inappropriate one.

A synthetic-image formation unit forms a vehicle-inside view point image showing a periphery of a vehicle in such a way as to transparently pass through a portion or an entirety of the vehicle and taken from a vehicle-inside view point inside a vehicle room. The synthetic-image formation unit further forms an interior-added image including an image of an interior member viewed from the vehicle-inside view point using pre-stored data for drawing an image of the interior member. A display control unit temporarily displays the interior-added image and displays animation which gradually raises a transparency of the image of the interior member, before displaying the vehicle-inside view point image, when changing over a display screen of the display to the vehicle-inside view point image in response to a user's manipulation on the vehicle.

Periphery-image display device and display control method

A peripheral image display device is configured to: acquire wheel speeds of a vehicle; determine a slip state or a non-slip state of a wheel of the vehicle based on the acquired wheel speeds; acquire multiple camera images from respective cameras; store, as a past image, the camera image indicating a range in a traveling direction of the vehicle; generate a peripheral image indicating a periphery of the vehicle by synthesizing the camera images, display the peripheral image on a display. In the non-slip state, the peripheral image display device displays a transparent image showing, in a transparent manner, a portion under a floor of the vehicle using the past image selected based on current wheel speeds is. In the slip state, the peripheral image display device deactivates the display of the transparent image.

A vehicle surrounding monitoring apparatus executes an underfloor object informing process for informing occupants of a vehicle of a probability that there is an object under the vehicle. When an object around the vehicle is detected, the vehicle surrounding monitoring apparatus memorizes information on the object as real-time object information. When the object which had been detected, is not detected, the vehicle surrounding monitoring apparatus acquires information on a moving of the object which had been detected for a predetermined time period as past object information, based on the memorized real-time object information. When determining that there is the object which had been detected under the vehicle, based on the past object information, the vehicle surrounding monitoring apparatus executes the underfloor object informing process.

A vehicle display control device includes: a locus determination unit determining a predicted locus of a wheel of a subject vehicle according to a steering angle of the subject vehicle; and a display processing unit displaying an image of a field view of the subject vehicle including a vehicle body of the subject vehicle on a display device, and the display processing unit superimposes the guide line indicating the predicted locus determined by the locus determination unit on the image of the field view regardless of the steering angle of the subject vehicle, while semi-transparently displaying a portion of the guide line which overlaps with the vehicle body, thereby allowing visibility of the vehicle body.
