Parking assist apparatus, parking assist method, and computer program
A parking assist apparatus includes a one-way traffic determiner that determines whether or not a vehicle is located on a one-way road, and a parking processor that, when it is determined that the vehicle is located on the one-way road case, does not perform a vehicle control for parallel parking including a path through which the vehicle reverses.
1. A parking assist apparatus associated with a vehicle, comprising:
a one-way traffic determiner that determines whether or not the vehicle is located on a one-way road based on road information from a map information processor installed in the vehicle or a captured image from a camera apparatus installed in the vehicle; and
a parking processor that judges not to perform a vehicle control for parallel parking including a path through which the vehicle reverses when the one-way traffic determiner determines that the vehicle is located on the one-way road.
2. The parking assist apparatus according to claim 1 , wherein,
when the one-way traffic determiner determines that the vehicle is located on the one-way road, the parking processor searches for a space available for parallel parking not including the path through which the vehicle reverses.
3. The parking assist apparatus according to claim 1 , further comprising:
a display processor that displays, on a displaying apparatus of the vehicle, a selection screen allowing a driver of the vehicle to select a space for which the parking assist apparatus is capable of assisting in the parallel parking,
wherein the parking processor searches for the space for which the parking assist apparatus is capable of assisting in the parallel parking, and
when the one-way traffic determiner determines that the vehicle is located on the one-way road, the display processor causes at least one space of a plurality of the spaces not to be displayed or selectable, the plurality of spaces being those for which the parking assist apparatus is capable of assisting in the parallel parking, the at least one space being one for which the parking assist apparatus is capable of assisting in the parallel parking performed by the vehicle control including the path through which the vehicle reverses.
4. The parking assist apparatus according to claim 3 , wherein,
when the one-way traffic determiner determines that the vehicle is located on the one-way road, the display processor displays, on the displaying apparatus, that the road on which the vehicle is located is for one-way traffic.
5. The parking assist apparatus according to claim 3 , wherein,
when one of the plurality of spaces displayed on the displaying apparatus is selected, the parking processor controls the vehicle such that the vehicle is parallel parked in the selected space.
6. The parking assist apparatus according to claim 1 , further comprising:
a notification processor that notifies that the vehicle control for parallel parking is not performed, when the one-way traffic determiner determines that the vehicle is located on the one-way road.
7. The parking assist apparatus according to claim 3 , wherein, when the one-way traffic determiner determines that the vehicle is located on the one-way road, the display processor displays a button that receives a start of the vehicle control for parallel parking, the button being displayed with an aspect indicating that the button is disabled.
8. The parking assist apparatus according to claim 7 , wherein
the display processor grays out the button, or displays an icon indicating prohibition over the button for the aspect indicating that the button is disabled.
9. The parking assist apparatus according to claim 2 , wherein, when the space available for parallel parking not including the path through which the vehicle reverses is not detected successfully, the parking processor displays, on a displaying apparatus of the vehicle, guidance information for guiding the vehicle to a parking lot available for parking.
10. A parking assist method performed by a parking assist apparatus associated with a vehicle, the parking assist method comprising steps of:
determining, by a one-way traffic determiner of the parking assist apparatus, whether or not the vehicle is located on a one-way road based on road information from a map information processor installed in the vehicle or a captured image from a camera apparatus installed in the vehicle; and
not performing, by a parking processor of the parking assist apparatus, a vehicle control for parallel parking including a path through which the vehicle reverses, when the one-way traffic determiner determines that the vehicle is located on the one-way road.
11. The parking assist method according to claim 10 , wherein,
when the one-way traffic determiner determines that the vehicle is located on the one-way road, a space available for parallel parking not including the path through which the vehicle reverses is searched for.
12. The parking assist method according to claim 10 , wherein:
a space for which the parking assist apparatus is capable of assisting in the parallel parking is searched for, and
a selection screen allowing a driver of the vehicle to select the space for which the parking assist apparatus is capable of assisting in the parallel parking is displayed on a displaying apparatus of the vehicle when the one-way traffic determiner determines that the vehicle is located on the one-way road, the selection screen being displayed in a state where a space for which the parking assist apparatus is capable of assisting in the parallel parking performed by the vehicle control including the path through which the vehicle reverses is caused not to be displayed or selectable.
13. The parking assist method according to claim 12 , wherein,
when the one-way traffic determiner determines that the vehicle is located on the one-way road, the displaying apparatus displays that the road on which the vehicle is located is for one-way traffic.
14. The parking assist method according to claim 12 , wherein,
when one of a plurality of the spaces displayed on the displaying apparatus is selected, the vehicle is controlled such that the vehicle is parallel parked in the selected space.
15. The parking assist method according to claim 10 , wherein, when the one-way traffic determiner determines that the vehicle is located on the one-way road, a notification of not performing the vehicle control for parallel parking is given.
16. The parking assist method according to claim 12 , wherein, when the one-way traffic determiner determines that the vehicle is located on the one-way road, a button that receives a start of the vehicle control for parallel parking is displayed with an aspect indicating that the button is disabled.
17. The parking assist method according to claim 16 , wherein
the button is grayed out, or an icon indicating prohibition is displayed over the button for the aspect indicating that the button is disabled.
18. The parking assist method according to claim 11 , wherein, when the space available for parallel parking not including the path through which the vehicle reverses is not detected successfully, guidance information for guiding the vehicle to a parking lot available for parking is displayed on a displaying apparatus of the vehicle.
