This invention involves the effect of multiple rules of the road at different elevation profiles on the speed constraints and therefore the overall fuel efficiency. A vehicle designed to optimize fuel consumption that is comprised of the rules of the road that determine maximum speed, minimum speed, stop signs, streetlights, and/or changes in other rules that determine the allowable speeds of the road, a localization mechanism, and an optimization engine to optimize the fuel economy by selecting a speed profile within that maintains the vehicle within the assigned range of speeds and minimizes fuel consumption. A wide variety of methods that typically are used to optimize the fuel efficiency of human drivers operating standard vehicles can also be applied towards autonomous vehicles driving at different speed constraints and with different changes in the elevation.

Systems, methods, and other embodiments described herein relate to generating a notification about a risk of a target vehicle toppling over due to wind. In one embodiment, a method includes determining a wind force of the wind at a location of the target vehicle and determining one or more characteristics of the target vehicle. The method includes determining whether there is a risk of the target vehicle toppling over based on the wind force of the wind and the one or more characteristics of the target vehicle. The method includes generating a notification about the risk.

Systems, methods, computer-readable media, and apparatuses for providing hazard detection and broadcast functions are provided. In some examples, sensor data may be captured by a mobile device, vehicle, or the like. The data may be used to detect a hazard, identify a type of hazard, and the like. One or more users or groups of users for notification of the hazard may be identified and one or more notifications may be transmitted to users within the group.

A facility for providing vehicle to vehicle event notification for connected and/or unconnected vehicles is disclosed. The facility enables a vehicle to detect an occurrence of a vehicle status trigger event and identify information describing an event type. The facility determines a priority of the vehicle status event based at least in part on the type of the vehicle status event. When the vehicle status event is to be reported to at least one other vehicle, the facility enables the vehicle to generate a vehicle status event message that includes the priority of the vehicle status event and at least a portion of the information describing the type of the vehicle status event. The vehicle status event message is then transmitted/broadcasted to at least one other vehicle.

Various aspects of a system and method for driving assistance along a path are disclosed herein. In accordance with an embodiment, a unique identifier is received from a communication device at an electronic control unit (ECU) of a first vehicle. The unique identifier is received when the first vehicle has reached a first location along a first portion of the path. A communication channel is established between the first vehicle and the communication device based on the received unique identifier. Data associated with a second portion of the path is received by the ECU from the communication device based on the established communication channel. Alert information associated with the second portion of the path is generated by the ECU based on the received data.

This disclosure relates to a distributed data center that includes resources carried by a fleet of vehicles. The system includes sensors configured to generate output signals conveying information related to the vehicles and/or the surroundings of vehicles. The system includes a remote computing server configured to maintain map data and distribute it to the fleet, including local map data to individual vehicles pertaining to their surroundings. Individual vehicles may compare the local map data with the information related to their individual surroundings. Based on such comparisons, individual vehicles may detect discrepancies between the local map data and the information related to their individual surroundings. The remote computing server may modify and/or update the map data based on the detected discrepancies.

A method for providing driving assistance based on a HD map includes acquiring information such as position of a vehicle and timing, and acquiring a speed of the vehicle based on the manner of driving, and acquiring distance an intersection in front of the vehicle and information from a HD map such as traffic light intersection ahead. Deciding such as whether the vehicle can pass through the intersection based on the speed of the vehicle, intersection distance, and the traffic light information and prompting and/or controlling the vehicle if it is determined that passage through is not possible. A vehicle-mounted apparatus applying the method is also disclosed.

A method for managing an urgency state of a first vehicle, implemented by a managing system. The method includes: receiving a first indication of the urgency state of the first vehicle; determining a list of potential itineraries including at least one potential itinerary of the first vehicle; and sending an alert message to at least one detecting element, located at a traffic lane, the at least one detecting element being determined as a function of the at least one potential itinerary of the first vehicle.

An in-vehicle wireless communication device according to the present embodiment is is mounted in a vehicle and includes a wireless communication unit that performs wireless communication with an external device provided outside of the vehicle and a processing unit that performs processing relating to communication, in which the processing unit determines a communication amount in an in-vehicle network provided inside of the vehicle, transmits communication amount information relating to the determined communication amount to the external device by the wireless communication unit, and receives data transmitted from the external device at a size corresponding to the transmitted communication amount information, by the wireless communication unit.

A travel information sensor senses travel information of a host-vehicle. A biological information sensor senses biological information of a driver. A camera unit senses a facial expression of the driver. A communication unit acquires an agitating degree indicating a degree to which an other-vehicle agitates the driver of the host-vehicle, via a network. An agitated degree calculation unit calculates an agitated degree indicating a degree to which the driver of the host-vehicle is agitated by the other-vehicle. A danger degree determination unit determines a danger degree including whether the driver of the host-vehicle is agitated by the other-vehicle, based on the agitated degree and the agitating degree. A presentation unit warns the host-vehicle of the danger degree if it is determined that the driver of the host-vehicle is agitated by the other-vehicle.
