Fixed offset method for hitch detection in hitch assist operation
A system for assisting in aligning a vehicle for hitching with a trailer includes a steering system that adjusts a vehicle steering angle, a braking system that adjusts a vehicle speed, an imaging system that receives image data of a drawbar assembly being receivable in a hitch receiver, and a controller. The controller is configured to detect an edge of the drawbar assembly from the image data, target an endpoint at a fixed offset from the edge and a stationary point on the vehicle, and maneuver, via the steering and braking systems, the vehicle along a path to align the endpoint with the trailer.
System and methods for vehicle alignment control
A vehicle system configured to control a trailer alignment routine comprises a hitch mounted on a vehicle and a controller. The controller is configured to identify a coupler position of a trailer and control motion of the vehicle toward an aligned position. The controller is further configured to calculate a stopping threshold relative to the coupler position. The stopping threshold comprises a semicircle concentric to the coupler position. The controller is further configured to control a braking procedure in response to the hitch passing the stopping threshold.
Saturated steering detection and operation for guided vehicle operation
A method for controlling a vehicle comprises identifying a first detected position of a trailer coupler in the sensor data and identifying a trajectory range of a hitch of the vehicle based on a steering angle range of the vehicle. In response to the first detected position being outside the trajectory range, the method may continue by calculating a nearby position within the trajectory range based on the trajectory range. The method further comprises maneuvering the vehicle aligning the hitch with the nearby position.
Trailer and vehicle collision detection and response during autohitch maneuvering
A vehicle system includes a vehicle brake system, an accelerometer mounted on the vehicle, and a controller. The controller receives a first signal from the accelerometer and, during reversing of the vehicle in a longitudinal direction, transmits an actuation signal to the vehicle brake system when the first signal from the accelerometer indicates a deceleration in the longitudinal direction above a predetermined rate within a predetermined time interval.
System and methods for vehicle alignment control
A vehicle control system comprises a sensor configured to capture sensor data and a controller configured to identify a coupler position of a trailer in the sensor data. The controller is further configured to control a vehicle alignment routine aligning the hitch with the coupler position and control an emergency braking operation in response to detecting an obstruction in the sensor data. The controller is configured to suppress the emergency braking operation in response to the obstruction corresponding to the coupler in the sensor data.
FIXED OFFSET METHOD FOR HITCH DETECTION IN HITCH ASSIST OPERATION
A system for assisting in aligning a vehicle for hitching with a trailer includes a steering system that adjusts a vehicle steering angle, a braking system that adjusts a vehicle speed, an imaging system that receives image data of a drawbar assembly being receivable in a hitch receiver, and a controller. The controller is configured to detect an edge of the drawbar assembly from the image data, target an endpoint at a fixed offset from the edge and a stationary point on the vehicle, and maneuver, via the steering and braking systems, the vehicle along a path to align the endpoint with the trailer.
VEHICLE HITCH BALL DETECTION SYSTEM
A vehicle control system includes an imager mounted with and directed to a rear of the vehicle and outputting image data, a vehicle speed sensor mounted with the vehicle and outputting vehicle speed data, and an image processor receiving the image data and the vehicle speed data. The image processor is programmed to monitor a signal from the vehicle speed sensor and, when the signal from the vehicle speed sensor indicates a vehicle speed above a predetermined minimum speed, execute a feature extraction function to locate a hitch ball mounted to the vehicle in the image data.
