Aspects of the present disclosure relate to using audible cues to guide a passenger to a vehicle having an autonomous driving mode. For instance, one or more processors of the vehicle may receive, from a server computing device, instructions to pick up the passenger at a pickup location. The one or more processors may maneuver the vehicle towards the pickup location in the autonomous driving mode. The one or more processors may receive a signal indicating that the passenger requests assistance locating the vehicle. The one or more processors may use the signal to generate the audible cues. The audible cues may be played by the one or more processors through a speaker of the vehicle in order to guide the passenger towards the vehicle.

A method for operating a control device of a motor vehicle driving by automation. The method includes determining a location of the motor vehicle, and acquiring driving-environment data of the motor vehicle, a control characteristic of the control device of the motor vehicle being formed in such a way that a driving behavior of at least one other road user is influenced in defined manner.

An audio notification system for an autonomous vehicle (AV) determines that the AV is within range of a user and emits a sound though a speaker of the AV to notify that the user that the vehicle has arrived. The audio notification system may include a sensor for sensing that the user has accessed the AV, and turns off the sound in response to the user accessing the AV. The audio notification may be generated according to one or more audio options, e.g., volume, pitch, or audio pattern.

Road vehicle comprising at least one electric motor; an acoustic system, which comprises at least one reproduction device, which generates a sound that can be associated with the electric motor; wherein the electric motor is mechanically connected to the reproduction device so as to be able to excite a resonant frequency thereof; and a control unit configured to control the electric motor so as to inject at least one sonority current or voltage, as an input, to the electric motor itself; wherein said at least one sonority current or voltage excites a frequency resulting in a vibration of said at least one reproduction device, which emits, due to the vibration, in the form of acoustic waves, a sound as a function of the injected sonority current or voltage.

A work vehicle includes a cutter device for cutting plant in a field, a storage section for storing plant cut by the cutter device, an inclination angle sensor for detecting an inclination angle ((θd)) of the vehicle body, a display device for displaying the inclination angle detected by the inclination angle sensor, and a reporting device for reporting the inclination angle exceeding a permissible inclination angle ((θa)).

Disclosed herein is a driver assistance apparatus including a camera which is installed in a vehicle, has a field of view around the vehicle, and is configure to acquire image data, and a controller including a processor configured to process the image data. The controller is configured to identify a gesture corresponding to a predesignated reference gesture based on the image data, and change a gear state of the vehicle and control a driving device of the vehicle to move the vehicle, based on identifying the gesture.

Aspects of the disclosure provide a method of facilitating communications from an autonomous vehicle to a user. For instance, a method may include, while attempting to pick up the user and prior to the user entering an vehicle, inputting a current location of the vehicle and map information into a model in order to identify a type of communication action for communicating a location of the vehicle to the user; enabling a first communication based on the type of the communication action; determining whether the user has responded to the first communication from received sensor data; and enabling a second communication based on the determination of whether the user has responded to the communication.

A motor vehicle includes an acoustic device configured to generate and capture acoustic waves, the acoustic device includes a vehicle part having a vibration region, and an actuator arranged thereon and configured to for excitation and detection of vibrations of the vehicle part in the vibration region, wherein the region is modified compared to an adjacent region of the vehicle part and has greater sensitivity to excitations in the frequency range of the acoustic wave.

A driver assistance system includes: a first speaker disposed on a vehicle and configured to output an omnidirectional sound; a second speaker disposed on the vehicle and configured to output a directional sound; and a controller configured to be electrically connected to the first speaker and the second speaker. The controller is configured to control the first speaker to output the omnidirectional sound while the vehicle is reversing and control, based on an obstacle being identified at a rear of the vehicle while the vehicle is reversing, the second speaker to output the directional sound directed toward the obstacle.
