A navigation system that searches for a route to a destination based on stored map data and provides navigation guidance to the destination along the route includes a controller that acquires road congestion information associated with the route, searches for the route to the destination based on a calculated search cost and changes a search cost based on predicted secondary congestion that is predicted based on acquired road congestion information, wherein a recommendable route that can avoid congestion is searched based on the search cost that has been changed based on the predicted secondary congestion.

Navigation system, and program and storage medium for use in the same

A navigation system that searches for a route to a destination based on stored map data that provides navigation guidance to the destination along the route, including a controller that searches for a first route to the destination as a route to be recommended based on a calculation of a search cost, detects whether the first route includes a curve, changes the search cost for any detected curve, searches for a second route to the destination based on the search cost that has been changed and employs the second route as the route to be recommended instead of the first route.

A navigation system includes an input device for inputting a destination, a current location detector for detecting current location of the vehicle, a camera for imaging an area to the rear of the vehicle, a route search program for searching for a route to the destination and a controller for providing guidance along the route determined by the route search. The controller controls the imaging by the camera according to route guidance information and determines whether a lane change is required in accordance with information obtained from the image. When it is determined that a lane change is required, the traffic situation in the vicinity surrounding the vehicle is recognized and guidance for the lane change is provided.

Navigation apparatus, navigation system and navigation method providing guidance for lane changes

Disclosed is a navigation apparatus for a vehicle, which detects a present location of a mobile body, searches for a route to a destination based on map data and roads ranked in accordance with a degree of details of roads, and outputs information of the searched route. An optimal route from a present location to a destination is searched for using the map data every predetermined time or every predetermined distance. A storage medium incorporates a program that has the capabilities of the navigation apparatus.

Navigation apparatus and storage medium therefor

An on-vehicle electronic device assembly includes a mount frame fixed on a metallic portion of a vehicle body, a carriable unit removably disposed in the mount frame, and a metallic urging member mounted on the mount frame for urging the carriable unit in a direction of moving the carriable unit away from the mount frame. The carriable unit includes a carrier case having a grounding metal piece insertion hole formed therein in a position corresponding to the urging member, a metallic chassis disposed in the carrier case so as to shield electronic components, and a grounding metal piece loosely fitted into the grounding metal piece insertion hole for electrically connecting the metallic chassis and the urging member.
