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.

There is provided e.g. an image recognizing apparatus which can increase the recognition rate of the image of a recognition target even when the recognition rate in the image recognition operation would deteriorate otherwise due to inability of obtaining good image information on the recognition target if the operation relied solely on picked up image information. The apparatus includes an image information obtaining section 3, an imaging position obtaining section 7, a land object information storing section 8, a land object information obtaining section 9 for obtaining, from the land object information storing section 8, the land object information on one or more land objects included within an imaging area of the image information, a determining section 15 for determining whether or not a plurality of recognition target land objects to be recognized are included within the imaging area of the image information, based on the obtained land object information and an image recognizing section 10 for recognizing an image of one recognition target land object, based on result of image recognition of another recognition target land object and on position relationship between the one recognition target land object and another recognition target land object based on the position information included in the land object information, if the determining section has determined that a plurality of recognition target land objects are included.

In a case where it is determined that a road surface marking exists within a specified range from a vehicle 2 (YES at S2), the road surface marking is recognized based on an image that has been acquired by a rear camera 3 (S3), an on-road distance from the vehicle 2 to a control object that is associated with the recognized road surface marking is computed (S5 to S7), and in a case where it has been determined that the on-road distance to the control object has become a specified distance (YES at S8), driving guidance and the vehicle control are performed in accordance with the type of the associated control object (S11).

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.

A shift lever position determining unit (11b1) determines whether a shift lever position of a vehicle (1a) satisfies predetermined conditions. If the shift lever position is determined to satisfy the predetermined conditions, a travel distance adding-up unit (11c) adds up an optimum shift lever position travel distance. If the shift lever position is determined not to satisfy the predetermined conditions, the travel distance adding-up unit (11c) adds up an inappropriate shift lever position travel distance. A fuel-saving driving rating unit (12) rates driving by a driver based on each added-up value added up by the travel distance adding-up unit (11c). A fuel-saving driving advice generating unit (13) notifies the driver of fuel-saving driving advice together with a rating result in accordance with the rating result. Therefore, it is possible to encourage the driver to select an optimum shift lever position with high fuel efficiency and thereby to improve the driver's knowledge and awareness of the fuel-saving driving.
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.
