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.

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.

A vehicle including a primary coil, a secondary coil, and a controller is provided. The controller may be programmed to position the secondary coil relative to a primary coil by, responsive to increases in voltage induced in the secondary coil by the primary coil, commanding the vehicle forward. The controller may be further programmed to, responsive to decreases in the voltage immediately following increases, commanding the vehicle forward a predetermined distance. The controller may be further programmed to, responsive to decreases in the voltage immediately beyond the predetermined distance, command the vehicle reverse. The controller may be further programmed to position the secondary coil relative to the primary coil by, responsive to increases in the voltage during reverse movement of the vehicle, command the vehicle reverse.

A vehicle hitch assistance system includes a steering system and a controller. The controller acquires position data for a coupler of a trailer, derives a vehicle path to position a center of a hitch ball of the vehicle at an interference offset past a centerline of the coupler in a driving direction of the vehicle path, and outputs a steering control signal to the steering system to maintain the vehicle along the path.

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.

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.

Driver misuse of an automatic braking system is determined by comparing the amount of time that a vehicle moves rearwardly until it is stopped, to the amount of time after the last actuation of a brake pedal and when the vehicle is stopped. If the ratio of no brake applied time to the total reverse time is greater than a predetermined value, the automatic braking system is considered to have been misused. Each misuse occurrence increments a counter that is stored in a non-transitory memory 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.

The disclosure relates to a driver assistance method, in which a vehicle performs a driving manoeuvre automatically, and a braking device, in particular a parking brake, is at least partially actuated during the performance of the driving manoeuvre so that a braking action is constantly exerted on the wheels of at least one axle so that a drive of the vehicle operates counter to the braking action of the braking device in order to move the vehicle. According to the disclosure, during the driving manoeuvre at least one operating parameter which is related to an undesired increase in the braking action exerted on at least one wheel is detected and evaluated, and a braking action on at least one wheel is reduced in accordance with the result of said evaluation.

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.
