摘要： A driving assistance apparatus is configured such that, in a case in which determination has been made there is a road marking within a predetermined range from a vehicle, the road marking is detected based upon an image acquired by a rear-side camera. In a case in which there is a single control target solely associated with the road marking thus detected, or in a case in which there are multiple control targets associated with the road marking, and the difference in the marking-target distance is equal to or greater than a driving control threshold distance, the target-vehicle distance, which is the distance between the vehicle and the control target that is a target for guidance and vehicle control, is calculated. The driving assistance apparatus performs guidance and vehicle control according to the control target based upon the target-vehicle distance thus calculated.

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.

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： 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.
