A preprocessing unit calculates a square sum SJ(t) of jerk J, and a driving characteristic calculation unit determines whether the jerk square sum SJ(t) is equal to or above a predetermined threshold value. The position/traveling direction determination unit determines the position and traveling direction of the vehicle. A troublesome driving place determination unit records an intersection at which the jerk square sum SJ(t) is calculated to be equal to or above the predetermined threshold value and the traveling direction of the vehicle at that time in association with each other in a troublesome driving place database. With reference to the troublesome driving place database, the troublesome driving place determination unit then calculates the risk cost at each intersection around the vehicle for each traveling direction. It is therefore possible to perform route guidance taking the driver's personal feeling into an account.

Navigation system performing route guidance for vehicle

A CPU of a navigation device includes a clock unit, a continuous driving time measurement unit that measures continuous driving time from a traveling start time, a course stage prediction unit, and a presenting information controller. The course stage prediction unit selects based on the traveling start time, a first transition determination reference time for transition from a 'first stage' to a 'middle stage' from prepared data of the first transition determination reference time and a second transition determination reference time for transition from the &#x201c;middle stage&#x201d; to a &#x201c;last stage&#x201d; from prepared data of the second transition determination reference time. The course stage prediction unit then predicts a course stage by comparing the continuous driving time with the selected transition determination reference times. Depending on the predicted course stage, the presenting information controller presents information convenient for a driver in the predicted course stage.

In image display apparatus, method, and program for an automotive vehicle, a surrounding of the vehicle is photographed, a plurality of display images are generated from a photographed data supplied from a photographing section, viewing points of the respective display images and looking down angles thereof being different from one another, one of the images generated is displayed through a display, and the display image generated and displayed through the display is switched to another one of the generated display images.

Image display apparatus, method, and program for automotive vehicle

In information presentation controlling apparatus and method, a detecting section detects a running state of a mobile body and a running environment thereof, a mental fatigue calculating section calculates a mental fatigue that an operator of the mobile body (specifically, a vehicle driver) suffers due to an operation of the mobile body (an automotive vehicle) from a result of detection by the detecting section, a producing section produces the information to the operator of the mobile body, and an information presentation controlling section controls the information to be produced to the operator of the mobile body through the producing section in accordance with the mental fatigue calculated by the mental fatigue calculating section.

In apparatus and method for navigating a mobile body such as a vehicle through a road map display image, an angle of a displayed traffic intersection with respect to, for example, a lateral axis crossing the traffic intersection is made coincident with an angle of an actually corresponding traffic intersection. That is to say, display coordinates at a predetermined part (for example, the traffic intersection) of a display image in a form of bird's eye view are modified, the predetermined part meaning a view focusing point or area, so that a scale in a longitudinal direction is made coincident with that in a lateral direction at the predetermined part.
