A display system for a vehicle and trailer is disclosed The system comprises an interface configured to receive a directional input and a controller in communication with the interface and a screen The controller is operable to receive a hitch angle and determine a heading direction of the trailer The controller is further operable to determine a predicted heading of the vehicle aligned with the trailer based on the hitch angle The predicted heading of the trailer is then displayed by the controller on the screen

Display system utilizing vehicle and trailer dynamics

A vehicle trailer backup assist system and method includes a hitch angle detection apparatus and a target monitor controller. The target monitor controller processes images acquired of the trailer towed by a towing vehicle to assist with placement of a target on the trailer. The target monitor controller also monitors the target and provides feedback to the user as to proper positioning of the target on the trailer. A target move detection routine detects movement of a target by processing the pixels of the image to determine if a new trailer has been connected. Further, a trailer connection monitoring routine monitors for a changed trailer based on loss of the hitch angle or target for a predetermined time period.

Trailer monitoring system and method

A vehicle system for estimating a trailer length is disclosed and includes a first sensor for measuring a wheel steer angle and a second sensor for measuring a hitch angle. A processor is in communication with the first and second sensors and is operable to determine a wheel steer angle change and a hitch angle change. The processor performs a first computation if the wheel steer angle change and the hitch angle change satisfy a threshold requirement and performs a second computation if at least one of the wheel steer angle change and the hitch angle change does not satisfy the threshold requirement.

Trailer length estimation in hitch angle applications

A display system for a vehicle attached to a trailer is provided herein. The system includes a display configured to show an aerial view of the vehicle and the trailer and a plurality of waypoints, each indicating a possible parking location for the trailer. The system also includes a device that interfaces with the display and is operable to select one of the plurality of waypoints and set a trailer orientation for the selected waypoint.

Trailer backup assist system with waypoint selection

A vehicle has a trailer backup steering input apparatus, a trailer backup assist control module coupled to the a trailer backup steering input apparatus, and an electric power assist steering system coupled to the trailer backup assist control module and. The trailer backup steering input apparatus is configured for outputting a trailer path curvature signal approximating a desired curvature for a path of travel of a trailer towably coupled to the vehicle. The trailer backup assist control module is configured for determining vehicle steering information as a function of the trailer path curvature signa. The electric power assist steering system is configured for controlling steering of steered wheels of the vehicle as a function of the vehicle steering information.

Trailer path curvature control for trailer backup assist

The reversing aid device has an operating control for input of a reference-angle between the longitudinal axis of the drawing vehicle and the trailer or between the longitudinal axis of the trailer and its trailer drawbar. The reference angle is adjusted by an automatic steering intervention. The operating control has two free moving spaces, where with movement of the operating control in one free moving space the reference angle increases or decreases.

A motor vehicle has a control device that is designed to change over an operating state of an extravehicular computer system for office applications between an active state, in which the computer system executes at least one piece of office application software, and a passive state, in which the computer system is deactivated.

Motor vehicle with a control device for an extravehicular computer system

A system for providing dynamic access to a vehicle via a plurality of devices. A device and/or a server of an authentication network stored fob data relating to one or more key fobs linked to the vehicle, and device data that includes data relating to one or more devices that are authorized to access the vehicle. The vehicle receives an access request indicating that a new device is requesting access to the vehicle, whereupon a challenge may be transmitted to one or more of the authorized devices. The one or more devices may respond, granting access to vehicle functions. The vehicle and/or authentication network generate a secure fob key and access limitations based on the response and transmit the secure fob key to the new device. The new device may be authenticated to access vehicle functions subject to the limitation based at least in part on the fob key.

Although recent statistics demonstrate a decrease in pedestrian fatalities, the absolute number of accident related deaths is sufficiently high to justify research in the area of vulnerable road user protection. Research has shown that situation awareness, which requires a significant amount of context information, is critical to timely intervention. Altered pedestrian behavior, due to traffic regulation, requires context information. For example, crosswalk presence and location knowledge can be of importance in pedestrian crossing scenarios. Therefore this paper discusses the implementation of a crosswalk detection algorithm, using Fourier transformation, augmented bipolarity, inverse perspective mapping template matching and edge orientation ratios for classification.
