A method of generating an overhead view of a tow vehicle and a trailer attached to the tow vehicle is provided. The method includes receiving first sensor system data from a sensor system and determining a trailer width based on the first sensor system data. The method includes receiving a second sensor system data from the sensor system and determining a trailer length based on the sensor system data. The method includes determining a separation distance between the trailer and the vehicle based on the first and/or second sensor system data. The method includes generating an overhead image including a vehicle representation and a trailer representation based on the trailer width, the trailer length, the separation distance, the vehicle length, and the vehicle width. The method also includes transmitting instructions to display the overhead image.

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 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.

In an onboard processing device, a parking path when a vehicle, which is a target vehicle, enters a parking place and a parking map including the parking place are obtained by an information obtaining unit, a peripheral environment of the vehicle is detected by a periphery detection unit, a vehicle position on the parking map is estimated by a vehicle position estimation unit, and a drive-out path when the vehicle is driven out from the parking place is set based on the estimated vehicle position, the parking path, and the detected peripheral environment by a path setting unit.

A parking assistance device includes an imager that captures an image of a surrounding of a vehicle, and a display that displays a guidance image for guiding the vehicle from a parking start position to a target parking position and displays a moving area in which the vehicle can move during a parking operation. An area and dimension of the moving area displayed on the display changes based on a change in a steering angle of the vehicle.

A hitch assist system is provided herein. The hitch assist system includes an imager for capturing one or more images of a hitch assembly and a trailer coupler. The imager is operably coupled with a movable panel. The hitch assembly includes a ball mount and a hitch ball. A controller is configured to generate an image that includes the hitch assembly, identify the hitch assembly within the image, estimate a ball mount length based on a predefined reference length and/or estimate a hitch ball height.

A surroundings monitoring apparatus according to embodiments, as an example, includes a control unit causing a display device to display a display image where an indicator which indicates a towed vehicle coupled to a towing vehicle is superimposed on a vehicle surrounding image including the towing vehicle and surroundings of the towing vehicle based on a captured image obtained by being imaged by an imaging unit which images the surroundings of the towing vehicle, the control unit acquiring towed vehicle information related to the towed vehicle and changing a display mode of the indicator based on the towed vehicle information. Thus, according to the surroundings monitoring apparatus of the embodiments, the towed vehicle may be easily imagined from the display image.

A display control device includes a video data acquisition unit acquiring video data from a camera that captures a video in a moving direction of a vehicle, a parking line recognition unit recognizing a parking line being a line of a parking space from the video data, a center line generation unit generating a center line of the parking space from the recognized parking line, a vehicle moving line generation unit generating a vehicle moving line extending in the moving direction of the vehicle from a position corresponding to a center part along a width of the vehicle, a superimposed video generation unit generating superimposed data being video data where the center line and the vehicle moving line are superimposed on the video data, and a display control unit transmitting the superimposed data to a display unit to display a video related to the superimposed data on the display unit.

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.

A hitch assist system is provided herein that includes a sensing system configured to detect a trailer and obstacles proximate the trailer. The hitch assist system also includes a controller in communication with the sensing system and configured to define a final vehicle heading direction relative to the trailer when a hitch ball of a vehicle is aligned with a coupler of the trailer; determine an uppermost/farthest position of the vehicle from the trailer; determine a lowermost/nearest position of the vehicle from the trailer; and determine a vehicle path that aligns the vehicle within the uppermost/farthest and lowermost/nearest positions.
