摘要： A device for informing to a driver a speed limit set for an own lane included in a multi-lane road is installed in a navigation system mounted on an automotive vehicle. The device includes a road surface camera for taking pictures of the speed limit painted on a road surface and informing devices such as a display panel and/or a speaker. The speed limit set for the own lane is specified based on the pictures taken by the road surface camera, and the specified speed limit is informed to the driver. Speed limits set for neighboring lanes may be also specified, and if they are different from the speed limit set for the own lane, this is informed to the driver together with the speed limits set for the neighboring lanes. It is not required to distinguish the own lane from among other lanes included in the multi-lane road because the speed limit set for the own lane is detected by the camera mounted on the own vehicle.
