Disclosed is a processing device that is mounted in a vehicle and is able to perform communication with a center server during a normal time. The processing device includes a controller configured to execute searching for one or a plurality of other vehicles with which a host vehicle is able to perform communication, in emergency where a situation of emergency occurs and communication with the center server is disrupted, inquiring the other vehicles searched by the search about whether or not to enable intervention control related to the situation, and deciding a center vehicle giving an instruction related to the intervention control from among the other vehicles replying to enable the intervention control and the host vehicle.

To identify driving event sounds during navigation, a client device in a vehicle provides a set of navigation directions for traversing from a starting location to a destination location along a route. During navigation to the destination location, the client device identifies audio that includes a driving event sound from within the vehicle or an area surrounding the vehicle. In response to determining that the audio includes the driving event sound, the client device determines whether the driving event sound is artificial. In response to determining that the driving event sound is artificial, the client device presents a notification to the driver indicating that the driving event sound is artificial or masks the driving event sound to prevent the driver from hearing the driving event sound.

Methods and systems for autonomous vehicle recharging or refueling are disclosed. Autonomous vehicles may be automatically refueled by routing the vehicles to available fueling stations when not in operation, according to methods described herein. A fuel level within a tank of an autonomous vehicle may be monitored until it reaches a refueling threshold, at which point an on-board computer may generate a predicted use profile for the vehicle. Based upon the predicted use profile, a time and location for the vehicle to refuel the vehicle may be determined. In some embodiments, the vehicle may be controlled to automatically travel to a fueling station, refill a fuel tank, and return to its starting location in order to refuel when not in use.

A method for managing an emergency state of a first vehicle, implemented by a remote server. The method includes: receiving an indication of the emergency state of the first vehicle; estimating a first geographical area in which the first vehicle is able to be positioned for a given time period; and sending an alert message to at least one detecting element, positioned at a traffic lane, said at least one detecting element being able to be positioned in the first geographical area for the given time period.

A system for granting access to an autonomous vehicle comprises the autonomous vehicle, a control device, and a communication device associated with the autonomous vehicle. The communication device receives a signal from a device associated with a user that indicates the user requests the autonomous vehicle to pull over. The control device pulls the autonomous vehicle over to a side of road traveled by the autonomous vehicle. The control device receives a credential associated with the user. The control device determines whether the credential is verified. In response to determining that the credential is verified, the control device grants the user to access the autonomous vehicle.

Techniques for detecting and responding to an emergency vehicle are discussed. A vehicle computing system may determine that an emergency vehicle based on sensor data, such as audio and visual data. In some examples, the vehicle computing system may determine aggregate actions of objects (e.g., other vehicles yielding) proximate the vehicle based on the sensor data. In such examples, a determination that the emergency vehicle is operating may be based on the actions of the objects. The vehicle computing system may, in turn, identify a location to move out of a path of the emergency vehicle (e.g., yield) and may control the vehicle to the location. The vehicle computing system may determine that the emergency vehicle is no longer relevant to the vehicle and may control the vehicle along a route to a destination. Determining to yield and/or returning to a mission may be confirmed by a remote operator.

An emergency vehicle audio detection apparatus uses phase lock loop technology to detect when an emergency vehicle is approaching. Emergency vehicle audio detector apparatus uses heads up display and a plurality of microphones mounted internally or externally on the vehicle to detect and warn drivers of emergency vehicles which may be approaching. The present apparatus uses phase lock loop techniques and filtering to determine if a difference between a plurality of signals is zero. The phase lock loop technique can distinguish if a sound picked up by a microphone is meaningful and then notify a driver of oncoming emergency vehicles. In some embodiments, a mute wire in an emergency vehicle audio detector apparatus could be installed to interact with a mute pin on a head unit display to mute audio volume once the emergency vehicle audio detector apparatus is activated. In some embodiments, a programming chip could be installed which would interact with an audio and a heads up display so that the display will give more information about an emergency vehicle in an area. In some embodiments, a speaker to audibly tell a driver to pull over could be installed in an emergency vehicle audio detector apparatus. In some embodiments, a display could have arrows showing from which direction an emergency vehicle is coming.

Systems and methods for performing operations based on LIDAR communications are described. An example device may include one or more processors and a memory coupled to the one or more processors. The memory includes instructions that, when executed by the one or more processors, cause the device to receive data associated with a modulated optical signal emitted by a transmitter of a first LIDAR device and received by a receiver of a second LIDAR device coupled to a vehicle and the device, generate a rendering of an environment of the vehicle based on information from one or more LIDAR devices coupled to the vehicle, and update the rendering based on the received data. Updating the rendering includes updating an object rendering of an object in the environment of the vehicle. The instructions further cause the device to provide the updated rendering for display on a display coupled to the vehicle.
