Abstract

A driving assistance apparatus to be mounted on a vehicle includes: an object detecting unit configured to detect an object outside the vehicle and acquire object information including a distance to the object; a vehicle speed detecting unit configured to detect a vehicle speed of the vehicle; and a processing unit configured to carry out driving assistance associated with an object on the basis of the object information when the object has been detected by the object detecting unit, and suppress the driving assistance when a predetermined condition that is changed on the basis of the vehicle speed detected by the vehicle speed detecting unit is satisfied.

First claim

1 . A driving assistance apparatus to be mounted on a vehicle, comprising:
an object detecting unit configured to detect an object outside the vehicle and acquire object information including a distance to the object; a vehicle speed detecting unit configured to detect a vehicle speed of the vehicle; and a processing unit configured to
carry out driving assistance associated with the object based on the object information when the object has been detected by the object detecting unit, and
suppress the driving assistance when the object has been continuously detected by the object detecting unit and a predetermined condition that is changed based on the vehicle speed detected by the vehicle speed detecting unit is satisfied.

2 . The driving assistance apparatus according to claim 1 , wherein
the condition includes a first condition and a second condition, the first condition is that a distance that the vehicle has traveled in a state where the object has been continuously detected by the object detecting unit exceeds a predetermined distance, the second condition is that a time during which the object has been continuously detected by the object detecting unit exceeds a predetermined time, and the processing unit is configured to select the first condition when the vehicle speed detected by the vehicle speed detecting unit is lower than or equal to a predetermined vehicle speed, and select the second condition when the vehicle speed detected by the vehicle speed detecting unit exceeds the predetermined vehicle speed.

3 . The driving assistance apparatus according to claim 2 , wherein
the predetermined distance is a distance to the object at the time when the object detecting unit starts detecting the object.

4 . The driving assistance apparatus according to claim 1 , wherein
the predetermined condition is that a time during which the object has been continuously detected by the object detecting unit exceeds a predetermined time, and the predetermined time is changed based on the vehicle speed detected by the vehicle speed detecting unit.

5 . The driving assistance apparatus according to claim 4 , wherein
the predetermined time extends as the vehicle speed detected by the vehicle speed detecting unit increases.

6 . The driving assistance apparatus according to claim 1 , wherein
the predetermined condition is that a distance that the vehicle has traveled in a state where the object has been continuously detected by the object detecting unit exceeds a predetermined distance, and the predetermined distance is changed based on the vehicle speed detected by the vehicle speed detecting unit.

7 . The driving assistance apparatus according to claim 6 , wherein
the predetermined distance extends as the vehicle speed detected by the vehicle speed detecting unit increases.

8 . The driving assistance apparatus according to claim 1 , wherein
the object detecting unit is configured to transmit a detection wave to an outside of the vehicle, detect the object outside the vehicle based on a reflected wave of the detection wave, and acquire the object information.
