Parking assist device
Disclosed is a parking assist device ( 100 ) including a parking assist control unit ( 5 ) that performs parking assist for a host vehicle ( 1 ) by using a first sensor ( 4 ) for parking assist disposed in the host vehicle ( 1 ), and a guide display control unit ( 25 ) that causes a display device ( 20 ) to display a guide display based on a first effective detection range (A L , A R ) of the first sensor ( 4 ) in a state in which the guide display is superimposed on a front view with respect to the host vehicle ( 1 ).
1. A parking assist device comprising:
a processor; and
a memory storing instructions which, when executed by the processor, causes the processor to perform processes of:
performing parking assist for a vehicle by using a first sensor for parking assist disposed in the vehicle; and
causing a display device to display a guide display based on an effective detection range of the first sensor in a state in which the guide display is superimposed on a front view with respect to the vehicle,
wherein the guide display shows information about the effective detection range, and shows an outer edge of the effective detection range on the front view that extends linearly and is superimposed on an obstacle that is within the effective detection range, the outer edge being set with respect to the vehicle,
the processor enables display of the guide display when the vehicle is stationary or when the vehicle is traveling at a traveling speed less than a reference speed, and
the guide display includes a left guide display based on the effective detection range on a left of the vehicle, and a right guide display based on the effective detection range on a right of the vehicle, and
when a position of the vehicle is on a road and this road has an opposite lane, the guide display on a side of the opposite lane, out of the left and right guide displays, is set to non-display.
2. The parking assist device according to claim 1 , wherein the processor performs automatic parking of the vehicle by using the first sensor.
3. The parking assist device according to claim 1 , wherein the guide display shows the outer edge and an inner edge of the effective detection range, the outer and inner edges being set with respect to the vehicle.
4. The parking assist device according to claim 3 , wherein the guide display includes a belt-shaped image corresponding to the effective detection range, and
the processor enables display of both a part of the belt-shaped image, the part including the outer edge, and a remaining part in different modes.
5. The parking assist device according to claim 1 , wherein the effective detection range includes a left effective detection range with respect to the vehicle and a right effective detection range with respect to the vehicle,
the guide display includes a left guide display based on the left effective detection range and a right guide display based on the right effective detection range, and
when a parking candidate area which is a candidate for a parkable area of the vehicle is included in any one of the left effective detection range and the right effective detection range, and when the parking candidate area is not included in any other of the left effective detection range and the tight effective detection range, the processor enables display of left guide display and the right guide display in different modes.
6. The parking assist device according to claim 5 , wherein when the parking candidate area is not included in any one of the left effective detection range and the right effective detection range, the processor sets left guide display or the right guide display to non-display.
7. The parking assist device according to claim 1 , wherein the processor further detects the obstacle existing in front of the vehicle by using a second sensor disposed in the vehicle, and enables display of the guide display in accordance with a result of the detection of the obstacle.
8. The parking assist device according to claim 7 , wherein the processor enables display of the guide display based on the effective detection range relative to the vehicle, and
the guide display is display in which an image corresponding to the effective detection range is displayed while the image is superimposed on the obstacle inside the effective detection range.
9. The parking assist device according to claim 8 , wherein the guide display is display in which a warning image is displayed while the image is superimposed on the obstacle outside the effective detection range.
10. The parking assist device according to claim 7 , wherein the processor enables display of the guide display based on the effective detection range relative to the obstacle, and
the guide display includes both a traveling direction of the vehicle and an edge of a range including the effective detection range, the edge being on a side opposite to a side facing the obstacle.
11. The parking assist device according to claim 7 , wherein the processor enables display of the guide display based on the effective detection range relative to the obstacle, and
the guide display includes an image of a virtual obstacle arranged along an edge of a range including the effective detection range, the edge being on a side opposite to a side facing the obstacle.
12. The parking assist device according to claim 1 , wherein the guide display includes a recommended path of the vehicle.
