摘要： A driving assistance device configured to assist a driver of a towing vehicle in vehicle operation includes: a captured image acquisition unit configured to acquire a captured image of a periphery of the towing vehicle, the captured image captured by an image capture device of the towing vehicle; an overhead image generation unit configured to, based on the captured image, generate an overhead image from above onto the periphery of the towing vehicle; a point calculation unit configured to calculate, in the overhead image, a position of a connection point for connecting a hitch ball of the towing vehicle with a coupler of a towed vehicle as an object to be towed by the towing vehicle; and an image display unit configured to display, on an image display device in the towing vehicle, the overhead image having an icon superimposed on the position of the connection point as an assistance image for assisting the driver in vehicle operation. In the driving assistance device, the point calculation unit calculates the position of the connection point in the overhead image based on a positional relationship between the image capture device and the hitch ball.

摘要： A trailer angle identification system includes an imaging device configured to capture an image. A controller is configured to receive steering angle data corresponding to a steering angle of a vehicle, receive vehicle speed data corresponding to a vehicle speed, and estimate an angle of the trailer relative to the vehicle by processing the image, the steering angle data, and the vehicle speed data in at least one neural network.

摘要： A steering system for a vehicle including at least one pair of wheel units which can be actuated and deflected independently of each other. Each wheel unit is paired with at least one sensor device for detecting a deviation from a specified deflection of the wheel units relative to each other, and each wheel unit is paired with at least one actuation device in order to actuate the wheel units. At least one control unit is designed to actuate the actuation devices of the wheel units when the sensor devices detect a specified deviation of the specified deflection of the wheel units relative to each other.

摘要： A machine includes a frame, a first steering arm, a second steering arm, a first hydraulic actuator coupled to the frame and the first steering arm, and a second hydraulic actuator coupled to the frame and the second steering arm. A first angle sensor measures a rotational displacement of the first hydraulic actuator relative to the first steering arm. A first link couples the first hydraulic actuator and the first sensor, and isolates movements other than the first rotational displacement. A second angle sensor measures a second rotational displacement of the second hydraulic actuator relative to the second steering arm. A second link couples the second hydraulic actuator and the second sensor, and isolates movements other than the second rotational displacement.

摘要： Steering a vehicle may include applying a net brake-steering force to a steered wheel sufficient to affect a steering moment upon the steered wheel sufficient to move the steered wheel away from a zero steering angle, and resisting movement of the steered wheel back toward the zero steering angle.

摘要： A vehicle control method includes determining whether a driving intention of a user is a U-turn intention or a left turn intention based on image information obtained by an imager. In response to determining that the driving intention of the user is the U-turn intention or the left turn intention an obstacle is detected that may cause a collision during a U-turn driving or a left turn driving based on the image information and obstacle information detected by an obstacle detector. In response, collision avoidance control is performed with the detected obstacle based on steering angle information of the vehicle.

摘要： Disclosed herein is a four-wheel independent steering apparatus. The apparatus includes a load estimator configured to receive, from a sensor disposed in a steering system, a value corresponding to a sensing by the sensor, and calculate an amount of load based on the value received from the sensor. The apparatus also includes a processor configured to receive, from an autonomous driving controller that is an upper-level controller, a steering angle reference, calculate an output value for allowing an actual steering angle to track the steering angle reference, based on the steering angle reference, the value from the sensor, and the amount of the load from the load estimator, and output the output value to the steering system.
