Abstract

A drive assist apparatus includes a recognition processing portion recognizing circumstances of surroundings of a vehicle, a drive assistance processing portion performing a drive assist control in accordance with the circumstances of the surroundings, a display processing portion displaying a change of the circumstances of the surroundings on a display portion, a detection processing portion detecting information related to a line of sight of a driver of the vehicle, and in a case where the circumstances of the surroundings of the vehicle change, an output processing portion outputting a first notice notifying the driver that the circumstances of the surroundings of the vehicle have changed outputting a second notice notifying again the driver that the circumstances of the surroundings have changed after the first notice is outputted if it is not detected that the line of sight of the driver is directed to the display portion.

First claim

1 . A drive assist apparatus comprising:
a recognition processing portion recognizing circumstances of surroundings of a vehicle; a drive assistance processing portion performing a drive assist control in accordance with the circumstances of the surroundings of the vehicle which are recognized by the recognition processing portion; a display processing portion displaying a change of the circumstances of the surroundings of the vehicle on a display portion in a case where the circumstances of the surroundings of the vehicle change; a detection processing portion detecting information related to a line of sight of a driver of the vehicle; in a case where the circumstances of the surroundings of the vehicle change,
an output processing portion outputting a first notice notifying the driver that the circumstances of the surroundings of the vehicle have changed by using another notifying portion which is separate from the display portion, and the output processing portion outputting a second notice notifying again the driver that the circumstances of the surroundings of the vehicle have changed by using the notifying portion after the first notice is outputted if it is not detected that the line of sight of the driver is directed to the display portion on the basis of a detection result by the detection processing portion;
the output processing portion outputting the second notice repeatedly until it is detected that the line of sight of the driver is directed to the display portion; the output processing portion outputting the second notice in an output manner which is different from an output manner of the first notice; and in a case where the output processing portion outputs the second notice twice or more, the output processing portion outputting the second notice which is outputted second time or after in an output manner that is different from an output manner of the second notice which was outputted in the past.

2 - 3 . (canceled)

4 . The drive assist apparatus according to claim 1 , wherein in a case where the output processing portion outputs the second notice twice or more, after the second notice is outputted for the first time, the output processing portion outputs the second notice repeatedly until the second notice is outputted for a predetermined number of times.

5 . The drive assist apparatus according to claim 1 , wherein in a case where the output processing portion outputs the second notice twice or more, after the second notice is outputted for the first time, the output processing portion outputs the second notice repeatedly until it is detected by the detection processing portion that the line of sight of the driver is directed to the display portion and it is detected by the detection processing portion that the driver performs a predetermined active action of an eye.

6 . The drive assist apparatus according to claim 1 , wherein
the notifying portion includes a sound output portion configured to output sound, and the output processing portion outputs the first notice and the second notice with the sound, by using the sound output portion.

7 . A drive assist apparatus comprising:
a recognition processing portion recognizing circumstances of surroundings of a vehicle; a drive assistance processing portion performing a drive assist control in accordance with the circumstances of the surroundings of the vehicle which are recognized by the recognition processing portion; a detection processing portion detecting information related to a line of sight of a driver of the vehicle; in a case where the circumstances of the surroundings of the vehicle change,
an output processing portion outputting a first notice notifying the driver that the circumstances of the surroundings of the vehicle have changed if it is detected that a driving posture including a direction of the line of sight of the driver satisfies a predetermined condition on the basis of a detection result by the detection processing portion, and the output processing portion outputting a first warning which warns the driver that the driving posture does not satisfy the predetermined condition if it is detected that the driving posture does not satisfy the predetermined condition on the basis of the detection result by the detection processing portion.

8 . The drive assist apparatus according to claim 7 , wherein that the driving posture satisfies the predetermined condition corresponds to that the direction of the line of sight of the driver is detected normally and the direction of the line of sight of the driver is directed to within a range of a predetermined angle relative to a travelling direction of the vehicle.

9 . The drive assist apparatus according to claim 7 , wherein if a state in which it is detected that the driving posture does not satisfy the predetermined condition continues even after the output processing portion outputted the first warning, the output processing portion repeatedly outputs a second warning which warns again the driver that the driving posture does not satisfy the predetermined condition until it is detected that the driving posture satisfies the predetermined condition.

10 . The drive assist apparatus according to claim 7 , further comprising:
a display processing portion displaying a change of the circumstances of the surroundings of the vehicle on a display portion in a case where the circumstances of the surroundings of the vehicle change; after the first notice is outputted, if it is not detected that the line of sight of the driver is directed to the display portion by the detection processing portion, the output processing portion repeatedly outputting a second notice which notifies again the driver that the circumstances of the surroundings of the vehicle have changed until it is detected by the detection processing portion that the line of sight of the driver is directed to the display portion.

11 . The drive assist apparatus according to claim 7 , wherein the output processing portion outputs the first notice or the first warning with sound, by using a sound output portion configured to output the sound.
