An autonomous emergency braking system includes a rear camera configured to acquire a rear image information of the vehicle, a hydraulic unit configured to supply brake fluid pressure to a wheel brake provided on each wheel; and a controller configured to receive the rear image information obtained through the rear camera, detect a ground area in the received rear image, detect a child candidate object on the detected ground area, determines a feature vector of a shape of a child's posture for the detected child candidate object, and determine whether the child candidate object is a child by comparing the determined feature vector with a preset feature vector, and brake the vehicle emergently through the hydraulic unit when it is the child.

A vehicle control system configured to control a braking operation of a hitch ball to a coupler on a trailer. The system may comprise a vehicle brake control system, a maneuvering system, an image sensor configured to capture an image data, and a velocity sensor. The system may also comprise a vehicle mass sensor configured to detect a vehicle mass and a controller.

Certain driver-assist features of a vehicle require incredibly precise longitudinal control of the vehicle. Achieving the precise control requires up-to-date knowledge of performance parameters of a brake system of the vehicle, which may vary extensively based on a wide set of influences outside the control of the brake system. The present disclosure proposes techniques to determine these parameters, for example, by stopping the vehicle early in maneuvering in order to study the brake performance, so that precise longitudinal control of the vehicle may be realized.

An intelligent ultrasonic system may include: a camera sensor unit configured to take an image of a road ahead of a driving vehicle; an ultrasonic signal input unit configured to receive an ultrasonic signal sensed through one or more ultrasonic sensors mounted on the vehicle; a feature extraction unit configured to extract a feature of the received ultrasonic signal; a data collision unit configured to collect one or more data related to a surrounding situation of the road on which the vehicle is driven; and a control unit configured to divide the surrounding situation into two or more classes based on the one or more data collected through the data collection unit, and change or reset an existing parameter to a parameter corresponding to any one class of the classes when the surrounding situation corresponds to the one class or is changed to the one class.

Methods and apparatus are disclosed to facilitate pedestrian detection during remote-controlled maneuvers. An example vehicle comprises external indicators and a processor and memory. The processor and memory are in communication with the external indicators and a remote device. The processor is configured to: determine whether the remote device is in a travel zone related to the vehicle; determine a risk assessment if the remote device is in the travel zone; and communicate a warning based on the risk assessment via the external indicators.

In one embodiment, a system perceives an environment surrounding an ADV including a vehicle in front of the ADV. The system determines whether the vehicle in front is slipping backwards based on the perception. The system determines whether the vehicle in front is situated on a road with a slope based on map information. The system determines whether a tail light or a brake light of the vehicle in front is turned on based on the perception. If it is determined that the vehicle in front is situated on a sloped road, is slipping backwards, and the tail light or the brake light is not turned on, the system calculates a time to impact or a distance to impact based on the distance and speed of the vehicle in front.

An emergency braking system according to an embodiment of the present invention, which performs emergency braking and brake release according to a position of an object detected while a vehicle moves backward, comprises a processor deriving a position of the object by processing data detected by a sensor, and a controller controlling emergency braking and brake release using the derived position of the object, wherein the controller releases a brake through different operation according to an area in which the position of the object is included after emergency braking of a plurality of areas into which a detecting area of the sensor is divided.

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.
