A parking assistance method provides parking assistance when parking a vehicle in a parking space equipped with a ground coil for supplying electric power via a wireless connection to a vehicle coil mounted on the vehicle, at least two ground marks indicating a position of the ground coil, and a parking frame. The parking assistance method switches from a bird's-eye image including the vehicle and a circumference of the vehicle as viewed from above the vehicle to an enlarged image showing a relative position between the ground coil and the vehicle coil on a larger scale than the bird's-eye image when an absolute value of a relative angle between a longitudinal direction of the parking frame and a front-rear direction of the vehicle is a predetermined value or smaller.

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.sub.L, A.sub.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).

The present invention relates to a vehicle control system (1) for controlling a trailer (5) coupled to a vehicle (3) during a reversing operation. The vehicle control system includes a processor (29) configured to determine an actual trailer travel direction (T.sub.ACT) based on one or more sensor signals. The processor (29) receives a demanded trailer travel direction (T.sub.DEM), for example from a user. A maximum permissible hitch angle (.sub.MAX) is calculated by the processor (29) and the demanded trailer travel direction (T.sub.DEM) is limited to an angle less than or equal to the calculated maximum permissible hitch angle (.sub.MAX). The present invention also relates to a vehicle (3) incorporating the vehicle control system (1); and a method of controlling the reversing of the trailer (5).

A periphery monitoring device includes: an acquisition section acquiring a steering angle of a vehicle; an image acquisition section acquiring a captured image from an image capturing section that captures an image of a periphery of the vehicle; a detection section acquiring detection information of an object around the vehicle; and a control section causing a display section to display a synthesized image including a vehicle image showing the vehicle and a periphery image showing the periphery of the vehicle based on the captured image. When the object is detected on a course of the vehicle traveling at the steering angle by a predetermined distance, the control section causes a virtual vehicle image to be displayed in the synthesized image to be superimposed on a course to the object with a position of the vehicle as a reference.

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.

A method for providing assistance in a parking maneuver of a vehicle combination of towing vehicle and trailer. The method includes: detecting a stationary object with the aid of a backup camera of the towing vehicle; ascertaining that the object is concealed for the backup camera by the trailer; and superimposing an image element representing the concealed object onto an image of the trailer in an image ascertained by the backup camera.

A cruise-assist image generation device includes: a steering-angle information acquisition unit acquiring steering angle information of a steering wheel; an additional line generation unit generating a cruise assist additional line corresponding to the acquired steering angle information and formed by combination of a given number of segments; and an additional line superimposing unit superimposing the generated cruise assist additional line on a taken image of the vehicle periphery to obtain a composite image. The additional line generation unit generates respective curved lines forming part or all of the given number of segments by quadratic curve approximation using coordinate data corresponding to the acquired steering angle information and including coordinates of two endpoints and one middle point representing each segment, and generating respective straight lines forming the remains of the given number of segments by collinear approximation using coordinate data corresponding to the acquired steering angle information and including coordinates of two end points representing each segment.

A vehicle periphery display device includes: an acquisition portion acquiring a captured image obtained by imaging a periphery of a vehicle with an imaging portion; and a display processing portion causing a display image that is a stereoscopic image of the vehicle and the periphery of the vehicle to be displayed on a display portion on the basis of the captured image. The display processing portion causes at least one of a contour guide line representing a contour of the vehicle, and a predicted course guide line that is a trajectory drawn by the contour guide line according to movement of the vehicle to be included in the display image, and changes a position of at least one of the contour guide and predicted course guide lines such that the contour guide and predicted course guide lines are present above a road surface when the vehicle is turned.

A vehicle periphery display device includes: an acquisition portion acquiring a captured image obtained by imaging a periphery of a vehicle with an imaging portion; and a display processing portion causing a display image including a vehicle image and a periphery image of the vehicle to be displayed on a display portion on the basis of the captured image. The display processing portion causes at least one of a contour guide line representing a contour of the vehicle image and having a first margin in a vehicle width direction of the vehicle image and a second margin in an advancing direction of the vehicle image, and a predicted course guide line that is a trajectory drawn by the contour guide line according to movement of the vehicle to be displayed in the display image, and changes at least one of the first and second margins when the vehicle is turned.

A display control device includes a video data acquisition unit that acquires video data from a camera that captures a video image in a moving direction of a vehicle, a vehicle motion detection unit that detects motion information containing a steering angle of the vehicle, an expected path line generation unit that generates a main expected path line extending along a planned moving path in accordance with the steering angle from a center part of a width of the vehicle, a superimposed video generation unit that generates superimposed data, the superimposed data being video data where the main expected path line is superimposed on the video data, and a display control unit that transmits the superimposed data to a display unit so as to display a video related to the superimposed data on the display unit.
