The invention provides an inter-vehicle communication apparatus for traveling safely and efficiently. In the invention, an inter-vehicle communication apparatus mounted on the vehicle on the information provider side is configured as an inter-vehicle communication apparatus that includes a communication unit for performing communication by broadcasting, and a storage unit for storing obstacle information during vehicle driving confirmed on a travel route of the own vehicle together with the time and position information, and broadcasts the obstacle information stored in the storage unit from the communication unit.

Systems and methods for providing physical navigation guidance via augmented reality (AR) environments are provided. An AR experience is generated based on navigation information including a starting location and a destination location. The AR experience comprises physical navigation guidance from the starting location to the destination location using virtual elements that are associated with either or both the starting location and/or the destination location. For example, virtual elements in the AR environment can transition from virtual elements associated with the starting location to virtual elements associated with the destination location as the user progresses from the starting location to the destination location.

An interface device connects to a mobile application running on a mobile device to provide vehicle navigation assistance. The interface device includes a microphone, a location determining component, a display, a plurality of indicator lights, a short-range communications transceiver, and a controller. The controller is configured to: receive a spoken instruction or query from a user via the microphone; send data associated with the spoken instruction or query to the mobile application running on the mobile device via the short-range communications transceiver; receive navigation data based on the spoken instruction or query from the mobile application running on the mobile device via the short-range communications transceiver; determine a current position based on one or more signals received via the location determining component; and provide at least one of a symbolic output or a textual output via the display based on the navigation data and the current position.

A navigation method is implemented by a group of portable devices which are associated with a map-and-information system and each of which is communicatively coupled to an instrument cluster device of a respective vehicle. The group of the portable devices includes a leader device and at least one follower device. The map-and-information system computes, for the follower device, a dynamic navigation path from the follower device to the leader device. The instrument cluster device of the vehicle that corresponds to the follower device perceivably outputs the dynamic navigation path.

Systems and techniques by which a navigation system provides directional information for vehicular travel that is customized based upon real-time conditions, a safety profile associated with a vehicle driver, and the safety assessment associated with the characteristics of road segments are disclosed. In one implementation, a method for a personalized vehicular navigation assessed dynamically based on risk tolerance includes retrieving data indicative of accident history associated with at least one of the road segments, retrieving data indicative of real-time condition of the road segments, and retrieving a user profile associated with the user. The method further includes calculating risk scores, based on the accident history and the real-time conditions and weighed based on tolerance level and the driver's history, associated with a plurality of proposed routes, identifying a personalized route based on the risk scores, and transmitting the identified personalized route to a device. The calculation of the risk scores includes combining, using a statistical inference method such as an Empirical Bayes method, the accident history and a statistical regression model based on features of a road segment to compute a likelihood of having an accident on the road segment.

An example method for assisting autonomous vehicle (AV) riders reach their destination after drop-off can include navigating the AV to a drop-off location associated with a user in the AV, receiving sensor data from sensors associated with the AV, determining, based on the sensor data, an orientation of the user in the AV and a location of the AV relative to a final destination of the user, generating a recommendation for how to exit the AV at the drop-off location based on the orientation of the user in the AV and the location of the AV relative to the final destination of the user, and providing the recommendation via a display, a speaker, a light-emitting device, and/or a client device, the recommendation including a visual indication of an exit direction or an AV door to use to exit the AV, audio instructions for exiting the AV, and/or visual exit instructions.

An example method for assisting autonomous vehicle (AV) riders reach their destination after drop-off can include receiving, by an autonomous vehicle (AV), a ride service request from a user, the ride service request specifying a pick-up location, a pick-up time, and a destination of a trip associated with the ride service request; navigating the AV to the pick-up location; providing the user a recommendation for where to sit within the AV, the recommendation being based on at least one of the destination of the trip, a drop-off location associated with the trip, environment conditions associated with the drop-off location, and an estimated egress location; receiving sensor data from one or more sensors associated with the AV; determining, based on the sensor data and the drop-off location, a pull-over location for dropping off the user; and navigating the AV to the pull-over location.

A multi-stop route selection system may include a telematics device associated with a vehicle having one or more sensors arranged therein, a mobile device, and a server computer. The server computer may receive driving data of a driver of the vehicle and a vehicle location from the telematics device, determine one or more driving behaviors of the driver based on the driving data, receive data regarding a calendar of the driver from the mobile device, identify a plurality of appointments in the calendar, determine a route comprising multiple destinations for the driver based on the vehicle location, the one or more driving behaviors, and the plurality of appointments, transmit the route to the mobile device, receive a request to add a new destination to the route from the mobile device, generate a modified route comprising the new destination, and transmit the modified route for the driver to the mobile device.

In an embodiment, the method for rendering the navigational direction to the user, the method comprising the steps of: determining location based information of a destination station; computing a current location of the user and a navigational direction toward the destination station from the current location of the user; selecting at least one mode of operation of a watch, wherein the at least one mode of operation includes rendering a navigational direction to the destination station on a watch dial; rendering a plurality of indicators within at least an inner area of the watch dial and an outer periphery of the watch dial; and rendering a pointer on the watch dial indicating the navigational direction to the user.

Systems and methods are provided for receiving a start location and a destination location, determining a road segment corresponding to the destination location, and identifying a node nearest the road segment corresponding to the destination location, whereby the node corresponds to a nearest left-hand node for a right-hand driving country or a nearest right-hand node for a left-hand driving country. The systems and methods further provide for generating a first route from the start location to the node nearest the road segment corresponding to the destination location, generating a second route from the node nearest the road segment corresponding to the destination location, to the destination location, and combining the first route and the second route to generate a final route. Thus, the final route comprises a route from the start location, through the node nearest the road segment corresponding to the destination location, to the destination location.
