  • Patent number: 11273868
    Abstract: A vehicular trailer assist system includes a camera disposed at a rear portion of a vehicle and having a field of view exterior of the vehicle. A control includes a processor for processing image data captured by the camera. The control, responsive to processing at the control of captured image data, determines a trailer angle of a trailer hitched to the vehicle. Responsive to determining the trailer angle, the control determines a trailer direction that is based at least in part on the determined trailer angle. The control is operable to determine a virtual destination location that is a location that is a predetermined distance from the trailer and in the determined trailer direction. Responsive to determining the trailer direction, and during a reversing maneuver of the vehicle and trailer, the control controls steering of the vehicle to direct the trailer in the determined trailer direction toward the virtual destination location.

  • Patent number: 11210801
    Abstract: An adaptive multi-sensor data fusion method based on mutual information includes: receiving an RGB image of a road surface collected by a camera; receiving point cloud data of the road surface collected synchronously by LIDAR; preprocessing the point cloud data to obtain dense point cloud data; and inputting the RGB image and the dense point cloud data into a pre-established and well-trained fusion network, to output data fusion results. The fusion network is configured to calculate mutual information of a feature tensor and an expected feature of input data, assign fusion weights of the input data according to the mutual information, and then output the data fusion results according to the fusion weights. In the new method, such information theory tool as mutual information is introduced, to calculate the correlation between the extracted feature of the input data and the expected feature of the fusion network.

  • Patent number: 11210436
    Abstract: A method for generating training data is disclosed. The method may include executing a simulation process. The simulation process may include traversing a virtual, forward-looking sensor over a virtual road surface defining at least one virtual railroad crossing. During the traversing, the virtual sensor may be moved with respect to the virtual road surface as dictated by a vehicle-motion model modeling motion of a vehicle driving on the virtual road surface while carrying the virtual sensor. Virtual sensor data characterizing the virtual road surface may be recorded. The virtual sensor data may correspond to what a real sensor would have output had it sensed the road surface in the real world.

  • Patent number: 11173901
    Abstract: A vehicle control apparatus includes an automatic steering control device. The automatic steering control device includes an override determiner, a target steering angle setter, and a target torque setter. The target steering angle setter sets a target steering angle in automatic steering control, based on surrounding information and running condition information. The target torque setter sets a target torque for making the vehicle turn so that a steering angle of the vehicle becomes the target steering angle set by the target steering angle setter. If a steering intention has been detected by the override determiner, during the steering intention being detected, the target steering angle setter sets the steering angle a predetermined length of time before, as the target steering angle.

  • Patent number: 11173957
    Abstract: A vehicle movement control apparatus of the invention executes a steering control to change a steering angle of an own vehicle at a predetermined changing rate to cause the own vehicle to move along a target movement line set in an own vehicle lane. The apparatus determines that a predetermined responsive characteristic condition is satisfied when another other vehicle moves in a vehicle lane next to the own vehicle lane, and the other vehicle exists in a predetermined area. The apparatus increases the predetermined changing rate to a larger changing rate when the predetermined responsive characteristic condition is satisfied, compared with when the predetermined responsive characteristic condition is not satisfied.
