A system according to the present disclosure includes an actuator control module and a damping ratio module. The actuator control module is configured to control an actuator of a vehicle to cause the vehicle to perform a yaw maneuver by rotating about its yaw axis. The damping ratio module is configured to determine a damping ratio based on an operating parameter measured during the yaw maneuver. The operating parameter includes at least one of a yaw rate of the vehicle, a yaw rate of a trailer connected to the vehicle, a lateral acceleration of the vehicle, a lateral acceleration of the trailer, a heading angle of the vehicle, and a hitch angle between a longitudinal axis of the vehicle and a longitudinal axis of the trailer.

A control system for a trailer or dolly, wherein the trailer or dolly comprises a perception sensor which is directed in a first travelling direction of the trailer or dolly and a coupling member for coupling with a vehicle further ahead in the first travelling direction, wherein the control system is configured to provide and/or use data from the sensor for a first control mode when the trailer or dolly is not coupled to the vehicle via the coupling member and to provide and/or use data from the sensor for a second control mode different from the first control mode when the trailer or dolly is coupled to the vehicle via the coupling member.

The disclosure generally pertains to a remote-control vehicle maneuvering system that includes a personal communication device configured to eliminate vehicle motion interference during a remote-control vehicle maneuvering operation. In an example scenario, an individual may stand in a vehicle having a trailer attached (or stand on the trailer) and perform actions upon the personal communication device so as to transmit commands to a vehicle controller of the vehicle for moving the vehicle backwards in a desired direction. The actions performed by the individual may include tilting the personal communication device to command the vehicle controller to increase a speed of the vehicle. While doing so, various factors such as an object on the road, may cause the vehicle to tilt, thereby increasing a tilt angle of the personal communication device and causing the vehicle to accelerate dangerously. The personal communication device is configured to eliminate interference caused by such factors.

Systems, methods, and other embodiments described herein relate to generating depth estimates of an environment depicted in a monocular image. In one embodiment, a method includes identifying semantic features in the monocular image according to a semantic model. The method includes injecting the semantic features into a depth model using pixel-adaptive convolutions. The method includes generating a depth map from the monocular image using the depth model that is guided by the semantic features. The pixel-adaptive convolutions are integrated into a decoder of the depth model. The method includes providing the depth map as the depth estimates for the monocular image.

A method for operating a driver information system in an ego vehicle is provided, wherein an operating state of a lighting apparatus of the ego vehicle is detected, and a driver information display is generated and output. The driver information display comprises a graphic ego object which represents the ego vehicle. In this context, the ego object comprises a rear depiction of the ego vehicle, wherein the ego object is generated depending on the detected operating state.

A method for operating a driver information system in an ego-vehicle is provided, wherein an operating state of a trailer device of the ego-vehicle is recorded. A driver information display is generated and output, wherein the driver information display comprises an ego-object which represents the ego-vehicle. In addition, the ego-object is represented from behind in a perspective view and the driver information display also comprises a lane object which represents a road section lying in front of the ego-vehicle in the direction of travel. The driver information display also comprises a trailer object which is formed according to a recorded operating state of the trailer device and which represents an attached device.

The disclosure relates to a method for assisting a towing vehicle in the event of a loss of traction via a trailer vehicle. The method includes determining a differential slip between a driven wheel and a driveless wheel of the towing vehicle via a brake control unit and generating an acceleration demand dependent on the determined differential slip. The method further includes transmitting the acceleration demand to a trailer brake control unit, generating an activation signal for an electric drive of the trailer vehicle in dependence upon the acceleration demand in the trailer brake control unit, transmitting an activation signal to the electric drive of the trailer vehicle and generating a drive torque via the electric drive in dependence upon the activation signal. The disclosure furthermore relates to a towing vehicle, a trailer vehicle, and a combination thereof for carrying out the method.

Systems, methods, and other embodiments described herein relate to navigating a trailer after the physical connection between a vehicle and trailer disconnects. In one embodiment, a method includes responsive to determining that a physical connection between a vehicle and a trailer has disconnected, determining trajectory information for navigating the trailer without a connection to the vehicle. The method includes communicating the trajectory information to the trailer to cause the trailer to follow a trajectory associated with the vehicle. The method includes monitoring whether the trailer is following the trajectory.

A tight turn wheel locking system may include a steering end stop sensor to output signals indicating that steered front wheels of a vehicle are in an end stop state towards a short turn side, an end stop steering wheel input sensor to output signals indicating end stop operator input to the steering wheel while the steered front wheels are in the end stop state, and a controller configured to automatically enter a tight turn mode in response to the end stop operator input satisfying a predetermined threshold. The controller, in the tight turn mode, outputs tight turn control signals that cause a vehicle braking system of the vehicle to lock a rear wheel of the vehicle corresponding to the short turn side.

An electronic control unit that is installed on a vehicle connected to a trailer and capable of towing the trailer changes travel control of the vehicle according to a type of the trailer when the trailer is connected to the vehicle.
