摘要： An accuracy error for measuring the position of an own vehicle is calculated based on the information of an execution history of map matching and the information of an update history of a map database. In addition, a predetermined map is referred to based on the calculated accuracy error, and an accuracy error level for performing positioning is specified from among plural stepwise levels. Then, the control level of assist control executed according to the position of the own vehicle is changed so as to correspond to the specified accuracy error level.

摘要： Based on positioning accuracy of an own vehicle required for appropriately carrying out assistance control carried out according to a position of the own vehicle, an execution condition for map matching correcting the position of the own vehicle is set. Specifically, setting is made in such a manner that, as the positioning accuracy is higher and an error thereof is smaller, an execution frequency of map matching becomes higher. Then, map matching is carried out according to the thus-set execution condition.

摘要： An object recognition device detects a position of a vehicle based on a running path obtained by GPS, vehicle speed, steering angle, etc., and also detects the position of the vehicle based on a result of recognition of an object obtained using a captured image of a camera. The device computes a positioning accuracy in detecting the vehicle position, which accuracy mostly deteriorates as a movement distance of the vehicle increases. Positional data of the object on the road to be recognized is stored in a map database beforehand. A recognition range of the road of the object to be recognized is set based on the detected position of the vehicle, a position of the object stored in the map database, and the computed positioning accuracy. The object is recognized for the set recognition range by processing of the captured image of the camera.

摘要： Systems, methods, and programs for determining whether a vehicle is off-road or on-road, store map data, determine the vehicle's current position; and obtain information about an area around the current position of the vehicle from the stored map data. The systems, methods, and programs obtain information related to a road-side zone of a road from the obtained information about the area around the current position of the vehicle, and determine that the road-side zone is crossed. The systems, methods, and programs may make an off-road determination if the determined current position of the vehicle was on-road before the crossing of the road-side zone and make an on-road determination if the current position of the vehicle was off-road before the crossing of the road-side zone.

摘要： Systems, methods, and programs for current position information management store map data and detect a current position of a vehicle using dead-reckoning navigation. The systems, methods, and programs monitor, based on the detected current position, a left-right position of the vehicle relative to a lane in which the vehicle is traveling. The systems, methods, and programs add up an amount of movement in the left-right direction and detect a lane change by comparing the added up amount of movement with the lane's width.
