Systems and methods to control autonomous vehicle motion

The present disclosure provides systems and methods that control the motion of an autonomous vehicle by rewarding or otherwise encouraging progress toward a goal, rather than simply rewarding distance traveled. In particular, the systems and methods of the present disclosure can project a candidate motion plan that describes a proposed motion path for the autonomous vehicle onto a nominal pathway to determine a projected distance associated with the candidate motion plan. The systems and methods of the present disclosure can use the projected distance to evaluate a reward function that provides a reward that is positively correlated to the magnitude of the projected distance. The motion of the vehicle can be controlled based on the reward value provided by the reward function. For example, the candidate motion plan can be selected for implementation or revised based at least in part on the determined reward value.

Trailer hitching assistance system with contact mitigation measures

A system for assisting in aligning a vehicle for hitching with a trailer includes a controller that receives the scene data and identifying the trailer within the area to the rear of the vehicle, derives a backing path to align a hitch ball mounted on the vehicle to a coupler of the trailer, outputting a powertrain control signal to the vehicle powertrain control system, and a brake control signal to the vehicle brake system to maneuver the vehicle, including reversing along the backing path and stopping the vehicle at an endpoint of the path, and outputs a video image to the vehicle human-machine interface including a graphical overlay on the image data. The graphical overlay indicates potential movement of the hitch ball past the coupler and being positioned in the image data between a bumper of the vehicle and the hitch ball.

An autonomous omnidirectional drive unit including a drive chassis supported on two independent, parallel, and coaxial drive wheels, actuated by two drive motors; a transport chassis the central area of which is superimposed on and connected to the drive chassis through a rotary joint, the transport chassis being supported on multiple omnidirectional wheels. The drive unit further includes a rotating device, actuated by a rotary motor, integrated in the rotary joint between the transport chassis and the drive chassis, which determines the angular position of the drive chassis with respect to the transport chassis, and a control device configured for adjusting at least the two drive motors and the rotary motor in a coordinated manner to obtain omnidirectional movement of the transport chassis.

Systems and Methods for Providing a Vehicle with a Torque Vectored K-Turn Mode
20230271612 · 2023-08-31 ·

Systems and methods are provided herein for operating a vehicle in a K-turn mode. The K-turn mode is engaged in response to determining that an amount that at least one of the front wheels of the vehicle is turned exceeds a turn threshold. While operating in the K-turn mode, forward torque is provided to the front wheels of the vehicle. Further, backward torque is provided to the rear wheels of the vehicle. Yet further, the rear wheels of the vehicle remain substantially in static contact with a ground while the front wheels slip in relation to the ground.

MULTI-MODE SWITCHABLE CAR

A multi-mode switchable car includes a car body, a bogie, a wheel assembly, a steering driving module, a steering locking structure and a locking sensing structure. The car body is provided with a control module, and multiple wheel driving programs are preset. The bogie is rotatably connected to the car body. The wheel assembly includes a hub motor connected to the bogie or the car body and a wheel-type component detachably connected to the hub motor, wheel forms are switchable by connecting different wheel-type components to the hub motor. The steering driving module drives the bogie. The steering locking structure locks the bogie when located in a locking position. The locking sensing structure acquires a position of the steering locking structure and is electrically connected with the control module, and the control module switches the wheel driving programs according to position information acquired by the locking sensing structure.

Parking robot for a transportation vehicle with at least two axles and method for operating a parking robot

A parking robot for a transportation vehicle having at least two wheel axles and a method for operating a parking robot. The parking robot includes a main robot part and a secondary robot part which each have a pair of wheel support arms on two opposite sides. The two-part parking robot then moves under the transportation vehicle with respective folded-in wheel support arms and disconnects the secondary robot part from the main robot part to position the main robot part and the secondary robot part each in a region of one of the wheel axles beneath the transportation vehicle and to lift up respective wheels of the respective wheel axle of the transportation vehicle by folding out the respective pairs of wheel support arms.

Collision avoidance support apparatus

When a collision avoidance steering control start condition becomes satisfied, a driving support ECU starts a steering control to avoid a collision with a frontward vehicle. The ECU prohibits the steering control when an indicated direction by turn indications of the frontward vehicle is the same as a planned direction of the steering control. The ECU sets the start condition to a first start condition, when the turn indicators of the frontward vehicle are not indicating a turning direction. The ECU sets the start condition to a second start condition, when the indicated direction is different from the planned direction. The first and second start conditions have been set such that an inter-vehicular distance between the host vehicle and the frontward vehicle of when the second start condition can be satisfied is shorter than one of when the first start condition can be satisfied.
