Abstract

A vehicular information display apparatus is provided which includes a display apparatus provided in a vehicle compartment and a display controller for controlling display of the display apparatus and is arranged to display specific information about a vehicle in a form to include a graphic on a screen of the display apparatus. The vehicular information display apparatus switches between a first display mode in which the specific information is displayed on a display region in the screen of the display apparatus and a second display mode in which the specific information is displayed on a display region smaller than the first display mode in the screen of the display apparatus. The display controller displays the graphic of the specific information by changing an orientation or a shape of the graphic when the display region is changed.

Claims11

Dependent claims

A risk prediction device comprising:

an observed information acquisition section that acquires observed information about surroundings of a vehicle;
a logical expression conversion section that converts the observed information acquired by the observed information acquisition section to a logical expression indicative of the surroundings of the vehicle;
a hypothetical reasoning section that, using a knowledge base, proves a risk predicted by weighted hypothetical reasoning from the logical expression obtained from conversion by the logical expression conversion section as a proof target, the knowledge base being a set of rules that are written in logical expression form to describe risks encountered during vehicle driving and general knowledge;
and
a reasoning result interpretation section that determines a risk level of the proved risk from a proof cost determined during reasoning by the hypothetical reasoning section, and associates the logical expression used for proof with the observed information.
