Driving support apparatus for vehicle
First Claim
1. A driving support apparatus for an own vehicle, the apparatus comprising:
- an autonomous sensor configured to acquire information including a position and a speed of another vehicle relative to the own vehicle;
a first determination part configured to use the position and the speed of the another vehicle acquired by the autonomous sensor to determine whether a first notification point in time has come, the first notification point in time being a point in time at which a notification that a likelihood of a collision between the own vehicle and the another vehicle exists is provided, and which generates a first notification request when it is determined that the first notification point in time has come;
an inter-vehicle communication device configured to acquire, from the another vehicle through wireless communication, information including a position of the another vehicle which is acquired based on GPS signals received by the another vehicle and a speed of the another vehicle;
an own vehicle position acquisition configured to receive GPS signals and acquire a position of the own vehicle based on the GPS signals;
an own vehicle speed detection configured to detect a speed of the own vehicle;
a second determination part configured to use the position and the speed of the another vehicle acquired by the inter-vehicle communication device, the position of the own vehicle acquired by the own vehicle position acquisition, and the speed of the own vehicle detected by the own vehicle speed detection to determine whether a second notification point in time has come, the second notification point in time being a point in time at which a notification that a likelihood of a collision between the own vehicle and the another vehicle exists is provided, and which generates a second notification request when it is determined that the second notification point in time has come; and
a notification device configured to provide a notification according to the first notification request at the first notification point in time, and to provide a notification according to the second notification request at the second notification point in time,wherein the notification device is configured not to provide the notification according to the second notification request at the second notification point in time, but to provide the notification according to the first notification request at the first notification point in time, if the second notification point in time has come in a period from a point in time earlier than the first notification point in time by a predetermined time length to the first notification point in time.

Abstract
A driving support apparatus for a vehicle comprises a first determination part which determines whether a likelihood of a collision between an own vehicle and another vehicle exists based on information acquired by an autonomous sensor and outputs a first notification request when a notification for the likelihood of the collision is required, a second determination part which determinates whether the likelihood of the collision based on information acquired by an inter-vehicle communication device and GPS sensor and outputs a second notification request when the notification for the likelihood of the collision is required, a warning determination part which inhibits the output of the second notification request by the second determination part when a time at which starts outputting the second notification request for a notification device by the second determination part has come until the time period from a time treq1 at which starts outputting the first notification request for the notification by the first determination part. Consequently, the apparatus is less likely to bother and/or confuse a driver, since the notification contents are not switched in a short time.
