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.

The wheel loader includes a rear detection section, a state detection section, and a controller. The rear detection section detects rearward of the vehicle body when moving backward. The state detection section detects a state of the vehicle body. The controller brakes the vehicle body based on the detection of the state detection section and the detection of the rear detection section.

Provided is a driver assistance system. The driver assistance system is provided in a vehicle.

The driver assistance system includes an image acquisition part configured to acquire image information about an obstacle; a yaw rate detector configured to detect a yaw rate of a vehicle body; and a controller configured to, when a shift lever is diagnosed as failure, recognize a rotation direction of the vehicle body based on the detected yaw rate of the vehicle body, recognize a position change of the obstacle in an image based on the acquired image information, and recognize whether a moving direction of the vehicle body is a backward direction or a forward direction based on the recognized rotation direction of the vehicle body and the recognized position change of the obstacle.

According to a method for assisting reverse driving of a combination (1), an actual value for a hitch angle of the combination (1) is determined by a computing unit (6) depending on sensor data generated by a hitch angle sensor. A hitch length of a trailer (3), given by a distance between a trailer body (11) and a hitch (7) of a vehicle (2), is determined depending on environmental sensor data of the combination (1). A collision value for the hitch angle is determined by the computing unit (6) depending on the hitch length, and the safety measure is triggered by the computing unit (6) depending on the actual value and the collision value for the hitch angle.

A system for assisting in aligning a vehicle for hitching with a trailer includes a steering system that adjusts a steering angle of the vehicle, a braking system that adjusts a speed of the vehicle, an imaging system that receives image data of a trailer disposed in an area proximate the vehicle, and a controller. The controller detects, within a threshold distance defined from a stationary point on the vehicle and the trailer, a position of a coupler from the image data, and, responsive to the position being less than the threshold distance, a status of the trailer based on the image data being indicative of a position of a hitch ball relative to the coupler within a second threshold. The controller maneuvers, via the steering and braking systems, the vehicle based on the status.

A system and a method for vehicle stop control are operable such that when it is detected that a vehicle is driving in a direction opposite to the direction of a current gear stage of the vehicle, the driver is warned and the vehicle enters an emergency braking state so as to reduce the risk of an accident and improve stability of a braking system. The vehicle stop control method performed by a controller of the vehicle includes steps of: converting vehicle driving environment information into data to be used as system input information; checking whether a controller related to each of driving and braking systems of the vehicle operates normally; determining whether the vehicle is driving in a reverse direction; and performing vehicle emergency stop control when the vehicle is driving in the reverse direction.

A vehicle rear warning system includes: a driving information detection portion that collects information measured from a radar and a camera sensor in a reverse mode of a vehicle; and a controller that separates a danger zone and a safe zone with reference to a fixed obstacle at a rear of the vehicle by performing fusion of the information measured from the radar and the camera in the reverse mode of the vehicle, and generates a collision event and controls warning and braking when a moving object approaching from the danger zone is detected, while limiting the warning and braking for a moving object existing in the safe zone.

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.

In an embodiment, a vehicle makes a determination, during a second ignition-on cycle of the vehicle, that a trailer brake output circuit of the vehicle was operated during a first ignition-on cycle of the vehicle preceding the second ignition-on cycle. In response to making the determination, the vehicle presents a query, via a user interface of the vehicle, whether to operate the trailer brake output circuit according to a previously-used trailer profile according to which the trailer brake output circuit was operated during the first ignition-on cycle preceding the second ignition-on cycle. The vehicle receives a reply, associated with the query, via the user interface and, in response to receiving the reply, operates the trailer brake output circuit based on the reply.

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.
