Abstract: Front left and right cameras are arranged at front left and right end parts, respectively, of a vehicle to capture a corresponding peripheral image around the vehicle. A control circuit controls a displaying operation of a display device based on a sensed current position of the vehicle and road map information in such a manner that when the vehicle approaches a junction where a current road, along which the vehicle currently travels, joins an encountering road, the peripheral images of front left and right cameras showing a corresponding view of the encountering road are displayed on the display device upon satisfaction of predetermined conditions.

Abstract: A vehicle includes an acceleration sensor that generates an output of an acceleration in a direction of the acceleration sensor. The output of the acceleration includes information on an orientation of the acceleration sensor relative to the vehicle. A method for determining an orientation of the vehicle includes (i) detecting a first output of the acceleration sensor; (ii) memorizing the first output as a reference orientation value, (iii) correcting the memorized reference orientation value, based on an average of outputs generated by the acceleration sensor while the vehicle travels after the first output is generated; and (iv) determining an orientation of the vehicle when the vehicle travels, based on the corrected reference orientation value and a second output of the acceleration sensor.

Abstract: A vehicle navigation system includes a map matching module and a voice recognition module. When the voice recognition module recognizes a user's voice input specifying an exit of a parking garage, the map matching module sets a current position of a vehicle to the specified position on a map. When the voice recognition module recognizes “high,” which indicates a elevated road, the current position is set onto the elevated road on the map. Likewise, the current position is set to a specific position on the map when the voice recognition module recognizes a user's voice input specifying a correct current position.
