7. The parking assist device according to claim 6 , wherein the hardware processor is configured to cause the display device to display an image for selecting whether to perform the second vehicle control.
8. The parking assist device according to claim 1 , wherein the hardware processor is configured to
determine a distance between the one position and the other position, and
performs the second vehicle control when the distance is larger than a predetermined value.
9. The parking assist device according to claim 8 , wherein the hardware processor is configured to
receive, from the power reception device, information on charging efficiency obtained in a case where contactless charging is started between the power reception device and the contactless power feeding device, and
perform the second vehicle control when the information represents that the charging efficiency is smaller than a reference value.
10. The parking assist device according to claim 9 , wherein the hardware processor is configured to suspend the second vehicle control when the distance between the one position and the other position is equal to or larger than the predetermined value or when the charging efficiency is equal to or larger than the reference value.
11. The parking assist device according to claim 9 , wherein the hardware processor is configured to output, to the power reception device, a signal for starting contactless charging when the distance between the one position and the other position is equal to or smaller than the predetermined value or when the charging efficiency is equal to or larger than the reference value.
12. The parking assist device according to claim 1 , wherein the parking assist device further comprising a determination unit, the determination unit being configured to receive, from the power reception device, information on charging efficiency in a case of starting contactless charging at the one position, and determine whether to perform the second vehicle control based on the information on charging efficiency.
