Abstract
A driving assistance apparatus that performs accurate driving assistance in accordance with actual road environment is provided. An electronic control unit (ECU) acquires shape information and vehicular swept path information about a subject vehicle and a nearby vehicle, representing vehicles and movement thereof as rectangular solids. A three-dimensional space is formed as a vehicular swept path for the rectangular solid and a road map generated based on the formed three-dimensional space. A notification is provided if the subject vehicle runs outside a space. Control support is provided to return the subject vehicle to an area indicated as safe.
Claims28
A driving assistance apparatus capable of being mounted on a subject vehicle and providing driving assistance for a driver of the subject vehicle, the apparatus comprising:
- a nearby vehicle dimension acquisition means for acquiring an exterior dimension of a nearby vehicle running near the subject vehicle;
- a running state information acquisition means for acquiring running state information indicating a running state of the nearby vehicle;
- a space formation means for forming a nearby vehicle virtual solid which is three-dimensional using the exterior dimension of the nearby vehicle and for forming a virtual three-dimensional space associated with a moving locus of the nearby vehicle virtual solid by following a vehicular swept path of the nearby vehicle included in the running state information acquired by the running state information acquisition means;
- a subject vehicle dimension acquisition means for acquiring an exterior dimension of the subject vehicle;
- a passing determination means for forming a subject vehicle virtual solid which is three-dimensional using the exterior dimension of the subject vehicle and for determining whether the subject vehicle virtual solid is capable of passing through the virtual three-dimensional space;
- and
- a notification control means for providing a notification to the subject vehicle of a determination result from the passing determination means as to whether or not the subject vehicle virtual solid which is three-dimensional is capable of passing through the virtual three-dimensional space.
A driving assistance apparatus capable of being mounted on a subject vehicle and providing driving assistance for the subject vehicle, the apparatus comprising:
- a nearby vehicle dimension acquisition means for acquiring an exterior dimension of a nearby vehicle running near the subject vehicle;
- a running state information acquisition means for acquiring running state information indicating a running state of the nearby vehicle;
- a space formation means for forming a nearby vehicle virtual solid which is three-dimensional using the exterior dimension of the nearby vehicle and for forming a virtual three-dimensional space as a moving locus of the nearby vehicle virtual solid, wherein the nearby vehicle virtual solid forms the moving locus by following a vehicular swept path for the nearby vehicle included in the running state information;
- a subject vehicle dimension acquisition means for acquiring an exterior dimension of the subject vehicle;
- and
- a passing determination means for forming a subject vehicle virtual solid which is three-dimensional, using the dimension of the subject vehicle and for determining whether the subject vehicle virtual solid is able to pass the virtual three-dimensional space formed by the space formation means,
- wherein the driving assistance apparatus provides driving assistance for the subject vehicle based on a determination result from the passing determination means as to whether or not the subject vehicle virtual solid which is three-dimensional is capable of passing through the virtual three-dimensional space.
