Parking assist device

摘要

Provided is a parking assist device such that, when a vehicle has reached an area corresponding to a backing start position, the angle of a current position with respect to a target parking position is placed in an appropriate range so as to facilitate subsequent guidance to the target parking position. In the parking assist device, when a vehicle (601) has reached any of a plurality of backing start positions (603 to 605), a state control unit (112) determines whether the angle of a current position with respect to a target parking position (602) is appropriate for guidance to a target parking position (602), and, if not, displays an angle correction indicating icon (606) on an image display means (102) to provide an indication for correcting the angle.

主权项

1. A parking assistance apparatus comprising:
a target parking position detection section that detects a target parking position of a vehicle being a parking assistance target; an angle detection section that detects an angle at which the vehicle approaches the target parking position; a vehicle speed detection section that detects a vehicle speed of the vehicle; a current position detection section that detects a current position of the vehicle based on the angle detected by the angle detection section and the vehicle speed detected by the vehicle speed detection section; a determining section that calculates a plurality of regions corresponding to a rearward-movement start position of the vehicle, each being capable of including an entire region of the vehicle and being wider than a region of the vehicle, based on the target parking position, and that determines, when the entire region of the vehicle reaches any of the plurality of regions, whether or not an angle correction of the current position is necessary with respect to the target parking position; and a display section that displays the target parking position and the plurality of regions, wherein, when the determining section determines, based on the current position, that there is a region unreachable by the vehicle among the plurality of regions, the display section erases the unreachable region from being displayed, wherein the determining section issues an instruction to correct the angle of the rearward-movement start position of the vehicle in the region where the vehicle has reached, when determining that the angle correction of the current position is necessary, the display section displays a first indicating image that indicates an angle correcting direction of the vehicle, when the determining section determines that the angle correction of the current position is necessary, and when the determining section then determines that the angle correction of the current position is not necessary, the display section erases the first indicating image indicating the angle correcting direction of the vehicle and displays a second indicating image indicating a rearward-movement start.
