Lane keeping assist apparatus of a vehicle with a trailer, a system having the same, and a method thereof
A lane keeping assist apparatus of a vehicle with a trailer, a system having the same, and a method thereof include a processor to request an advancing vehicle to control partial braking over the trailer of the advancing vehicle based on a lane departure amount of the advancing vehicle when the advancing vehicle departs from a lane.
Localization Methods And Architectures For A Trailer Of An Autonomous Tractor-Trailer
Systems and methods for localization of a trailer of an autonomous tractor-trailer are described herein. Some implementations can determine a sector area in an environment of the autonomous tractor-trailer that is predicted to include the trailer, determine a subset of an LIDAR data that is generated by LIDAR sensor(s) of an autonomous tractor of the autonomous tractor-trailer and that is predicted to include the trailer based on the sector area, generate a trailer pose instance of a trailer pose of the trailer based on the subset of the LIDAR data, and cause the trailer pose instance to be utilized in controlling the autonomous tractor-trailer. Additional or alternative implementations can utilize particular LIDAR sensor(s) in generating the trailer pose instance, such as phase coherent LIDAR sensor(s) or polarized LIDAR sensor(s).
TECHNIQUES FOR DYNAMIC TRAILER MONITORING USING FREQUENCY MODULATED CONTINUOUS WAVE BASED LIDAR
A method for dynamic monitoring of a trailer using a light detection and ranging (LIDAR) system comprising: scanning the trailer using a set of sensors positioned on a tractor towing the trailer to generate a point cloud of the trailer and monitoring an initial set of motion data of the trailer produced within the point cloud, wherein the motion data comprises velocity data related to the trailer. Provided the initial set of motion data is outside a safe operational threshold, instructing the tractor to perform a corrective action that causes a subsequent set of motion data of the trailer to be within the safe operational threshold. Provided the initial set of motion data is within the safe operational threshold, continuing to monitor the initial set of motion data until the initial set of motion data is outside the safe operational threshold.
Systems and methods to address jackknifing in autonomous vehicles
The technology relates to articulated autonomous vehicles that can potentially jackknife. To avoid or mitigate such hazardous conditions, the current state of the vehicle is evaluated against the vehicle's planned trajectory, for instance as it drives along a freeway or surface streets. When the evaluation indicates a likelihood of jackknifing, an automated braking approach is implemented using elective braking to stabilize the vehicle. The braking approach can depend on whether the situation involves tractor jackknifing or trailer jackknifing, and one or more different braking mechanisms can be employed for a selective modulation of the braking profile to address actual jackknifing or to prevent the vehicle from entering a jackknifing situation.
USER CONFIGURABLE TRAILER
Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.
Periphery monitoring device
A periphery monitoring device includes a coupling determiner that determines whether a towed vehicle is coupled to a towing vehicle to which the towed vehicle can be coupled; a target setter that sets a target moving position to be a target for moving at least the towed vehicle coupled to the towing vehicle; a storing controller that stores, as a moving target image, an image, including the target moving position, of a peripheral image generated by as imager provided at the towing vehicle; and an image controller that displays the stored moving target image in association with the towing vehicle or the towed vehicle included in a current image generated by the imager and currently displayed on a display device.
SYSTEM AND METHOD FOR PROBING PROPERTIES OF A TRAILER TOWED BY A TOWING VEHICLE IN A HEAVY-DUTY VEHICLE COMBINATION
A system for probing properties of a trailer towed by a towing vehicle in a heavy-duty vehicle combination. The system comprises at least one torque generating component for inducing movements of the trailer relative to a yaw axis of the trailer; a control unit configured to, during driving of the vehicle combination, activate the torque generating component and apply a pre-determined control action to the torque generating component so as to excite oscillations of the trailer; and at least one detection unit configured to detect the resulting oscillations of the trailer, wherein the control unit is configured to, based on the detected resulting oscillations, determine one or more properties of the trailer. The invention also relates to a probing method.

Method for determining a maximum speed limit for a reversing vehicle combination
A method is provided for determining a maximum speed limit for a reversing vehicle combination that includes a towing vehicle and at least one towed trailer. The method includes determining a maneuver that is to be performed by the vehicle combination, simulating the complete maneuver in advance by using a control algorithm and a state space model, thereby obtaining the steering behavior of the vehicle combination during the maneuver, and calculating the maximum speed limit for the vehicle combination during the maneuver by using at least one predefined limiting condition. A maximum speed limit for a reverse assistance function can be estimated in advance, which allows for a faster and more efficient reversing of the vehicle combination, and at the same time allows for an improved comfort for the driver.
Display system utilizing vehicle and trailer dynamics
A vehicle and trailer display system is disclosed. The display system includes a plurality of imaging devices disposed on the vehicle, each having a field of view. The display system further includes a screen disposed in the vehicle operable to display images from the imaging devices. A controller is in communication with the imaging devices and the screen and is operable to receive a hitch angle corresponding to the angle between the vehicle and the trailer. Based on the hitch angle, the controller is operable to select a field of view of an imaging device to display on the screen.
