Parking support information display method and parking support device

1. A method of displaying parking assist information, the method being used in a parking assist apparatus comprising a display and a control device,

comprising:

displaying by the control device a first parking space in a first display form on the display, the first parking space satisfying a parking condition that is preliminarily defined; and

in response to determining or detecting, at a current time, that the first parking space will not at a first time later than the current time satisfy the parking condition or that a second parking space other than the first parking space will at a second time later than the current time satisfy the parking condition, displaying by the control device the first parking space by a second display form different from the first display form on the display.

2. The method according to claim 1 , wherein a first time from when the first parking space is displayed in the second display form to when the first parking space becomes non-displayed is set longer as a speed of a subject vehicle increases.

3. The method according to claim 1 , wherein a period of a first time from when the first parking space is displayed in the second display form to when the first parking space becomes non-displayed is set such that the first time set when the first parking space and the second parking space are adjacent to each other is longer than the first time set when the first parking space and the second parking space are not adjacent to each other.

4. The method according to claim 1 , further comprising:

in response to estimating that the second parking space other than the first parking space will satisfy the parking condition, displaying, by the control device, the second parking space in a third display form on the display and then displaying the second parking space in a fourth display form on the display.

5. The method according to claim 1 , wherein a second time from when the second parking space is displayed in a third display form to when the second parking space is displayed in a fourth display form is set in accordance with a speed of a subject vehicle.

6. The method according to claim 4 , wherein a period of a second time from when the second parking space is displayed in the third display form to when the second parking space is displayed in the fourth display form is set such that the second time set when the second parking space is adjacent to another parking space into which parking is possible is longer than the second time set when the second parking space is not adjacent to another parking space into which parking is possible.

7. The method according to claim 1 , further comprising:

detecting, by the control device, available parking spaces into which parking is possible;

detecting, by the control device, a recommended parking space among the available parking spaces as the first parking space, the recommended parking space satisfying a parking recommendation condition that belongs to the parking condition; and

displaying, by the control device, the recommended parking space in the first display form.

8. The method according to claim 7 , further comprising:

when the first parking space is extracted as the recommended parking space at first timing in a process of extracting the recommended parking space, extracting, by the control device, the second parking space that is not adjacent to the first parking space as the recommended parking space at second timing after the first timing.

9. The method according to claim 1 , further comprising:

when the first parking space is displayed in the first display form, notifying it, by a notification device of the parking assist apparatus, in a first notification mode; and

when the first parking space is displayed in the second display form, notifying it, by the notification device, in a second notification mode different from the first notification mode.

10. The method according to claim 5 ,

further comprising:

when the second parking space is displayed in the third display form, notifying it, by a notification device of the parking assist apparatus, in a third notification mode; and

when the second parking space is displayed in the fourth display form, notifying it, by the notification device, in a fourth notification mode different from the third notification mode.

11. The method according to claim 1 , further comprising:

when a time period between timing at which the first parking space satisfies the parking condition and timing at which the second parking space satisfies the parking condition is not longer than a predetermined time period, prohibiting, by the control device, a display form of the first parking space from switching from the first display form to the second display form; and

continuing to display, by the control device, the first parking space in the first display form even when it is estimated that the second parking space other than the first parking space will satisfy the parking condition.

12. A parking assist apparatus comprising a display and a control device,

the control device being configured to:

display a first parking space in a first display form on the display, the first parking space satisfying a parking condition that is preliminarily defined; and

in response to estimating or detecting, at a current time, that the first parking space will at a first time later than the current time not satisfy the parking condition or that a second parking space other than the first parking space will at a second time later than the current time satisfy the parking condition, display the first parking space by a second display form different from the first display form on the display.

13. The method according to claim 5 , wherein a period of the second time from when the second parking space is displayed in the third display form to when the second parking space is displayed in the fourth display form is set such that the second time set when the second parking space is adjacent to another parking space into which parking is possible is longer than the second time set when the second parking space is not adjacent to another parking space into which parking is possible.

14. A method of displaying parking assist information, the method being used in a parking assist apparatus comprising a display and a control device, comprising:

displaying by the control device a first parking space in a first display form on the display, the first parking space satisfying a parking condition that is preliminarily defined; and

in response to estimating or detecting that the first parking space will not at a first time later than a current time satisfy the parking condition and that a second parking space other than the first parking space will at a second time later than the current time satisfy the parking condition, displaying by the control device the first parking space by a second display form different from the first display form on the display.
