A vehicular trailer guidance system includes an electronic control unit (ECU) and a rear backup camera disposed at a vehicle. A human machine interface (HMI) is operable in (i) a trailer left-backup mode, (i) a trailer straight-backup mode and (iii) a trailer right-backup mode. Responsive to selection by the driver of the trailer left-backup mode or trailer right-backup mode, the ECU sets a desired trailer angle of the trailer tongue leftward or rightward to an angle that is commensurate with a driver-selected setting of an input device. Responsive to selection by the driver of the trailer straight-backup mode, the ECU sets the desired trailer angle to a zero degree angle. The ECU, while the vehicle is backing up the trailer, controls the power steering system of the vehicle to steer the vehicle to back up the trailer to have the determined trailer angle coincide with the set desired trailer angle.

A vehicle driving assistance apparatus executes a collision avoidance control to avoid a collision of an own vehicle with an object ahead of the own vehicle by forcibly braking and stopping the own vehicle before the object when a collision condition that the own vehicle collides with the object, becomes satisfied. The vehicle driving assistance apparatus acquires information on a situation behind the own vehicle as rearward detection information when the own vehicle tows a trailer, acquires an angle between a moving vector of the own vehicle and a moving vector of the trailer as a towing angle. and keep the collision avoidance control unexecuted even when the collision condition becomes satisfied when a forbiddance condition that the towing angle is equal to or greater than a predetermined towing angle, is satisfied.

A system for determining a distance between a camera and a hitch ball of a vehicle. The system includes a camera configured to be mounted on a vehicle and an electronic processor connected to the camera. The electronic processor is configured to determine a first position and a second position associated with a point on a trailer, determine an angle of rotation between the first position and the second position, and using the first position, the second position, and the angle of rotation, determine a null space of a matrix. In one example, the matrix is

[00001]$A=\left[\begin{array}{ccccc}1& 0& 0& -{\mathrm{cu}}_{\mathrm{xo}}& {\mathrm{cl}}_x\\ 0& 1& 0& -{\mathrm{cu}}_{y0}& {\mathrm{cl}}_y\\ 0& 0& 0& {\mathrm{cu}}_{z0}& -{\mathrm{cl}}_z\\ 0& 0& 1& \frac{-{\mathrm{cu}}_{z0}}{{\mathrm{cu}}_{z1}}{\mathrm{cu}}_{x1}& {\mathrm{cl}}_x\\ -\cos \delta & \sin \delta & 1& 0& 0\end{array}\right]$

and the null space of the matrix includes a value of a distance (d.sub.l) between the camera and the hitch ball. The electronic processor is further configured to perform an autonomous or semi-autonomous vehicle operation based on the distance (d.sub.l) between the camera and the hitch ball.

A method for estimating an effective length of a first vehicle segment of a vehicle combination, the vehicle combination comprising a towing vehicle which is connected to the first vehicle segment via a first articulation joint and a perception sensor mounted on one of the towing vehicle and the first vehicle segment and arranged to obtain an image of the other one of the towing vehicle and the first vehicle segment; the method comprising identifying that the vehicle combination is provided in a first steady vehicle state, identifying that a turning and driving manoeuvre is initiated, identifying when the vehicle combination reaches a second steady vehicle state, determining a time period required for driving the vehicle combination from the first steady vehicle state to the second steady vehicle state, and estimating the effective length by use of the time period, the specific angular change, and the specific speed.

A remote autonomous driving control management apparatus, a system including the same, and a method thereof are provided. The remote autonomous driving control management apparatus is configured to authenticate a remote control terminal, obtains a surrounding image from an autonomous vehicle, receives a parking position from the remote control terminal, and performs autonomous parking or autonomous stop by remote control, based on the parking position and the surrounding image. The remote autonomous driving control management apparatus shares an accurate position through communication to facilitate precise remote control of the autonomous vehicle.

Operating an autonomous machine using analysis of machine vibration while it is operational. Accelerometers are used to measure the machines vibrations while it is being operated. If the vibrations exceed a predetermined acceleration a controller adjust the velocity of the machine to prevent/reduce further vibrations.

A method of controlling a mobile machine having a set of ground engaging elements includes receiving an image of terrain proximate the mobile machine, detecting a contour of the terrain, determining a projected path of the set of ground engaging elements based on the detected contour of the terrain, and controlling a display device to display the image with an overlay representing the projected path of the ground engaging elements.

An autonomous vehicle (AV) includes features that allows the AV to comply with applicable regulations and statutes for performing safe driving operation. Example embodiments relate to an autonomous vehicle having a trailer coupled to a rear thereof. An example method includes continuously predicting a trailer trajectory that is distinct from a planned trajectory of the autonomous vehicle. The method further includes determining that the predicted trailer trajectory is within a minimum avoidance distance away from a stationary vehicle located on a roadway on which the autonomous vehicle is located. The method further includes modifying the planned trajectory of the autonomous vehicle such that the predicted trailer trajectory satisfies the minimum avoidance distance. The method further includes causing the autonomous vehicle to navigate along the modified trajectory based on transmitting instructions to one or more subsystems of the autonomous vehicle.

A method and system for operating a vehicle's trailer reverse assist system is disclosed, including receiving vehicle sensor system data from one or more sensors supported by the vehicle. Based upon the received vehicle sensor data, a trailer pitch angle and a trailer roll angle of a coupled trailer are estimated relative to the vehicle. Surface unevenness of a surface traversed by the vehicle and the trailer is estimated, based upon the estimated trailer pitch angle and the estimated trailer roll angle. One or more parameters of the trailer reverse assist system or of the tow vehicle are adjusted based upon the estimated road surface variance. The trailer reverse assist system of the tow vehicle is subsequently operated using the adjusted one or more parameters.

An apparatus and method for controlling articulation of an articulated vehicle may prevent jackknifing of the articulated vehicle driven backwards. The apparatus includes a hitch angle calculator configured to calculate a desired hitch angle based on a steering angle and a speed of the articulated vehicle, an error calculator configured to calculate an error between the desired hitch angle and an actual hitch angle of the articulated vehicle, a moment generator configured to generate a moment for controlling the articulation of the articulated vehicle based on the error, and an articulation controller configured to control the articulation of the articulated vehicle based on the moment.
