A plurality of active vehicle applications that request localization data provided by one or more of the localization data sources can be identified. Based on the active vehicle applications, a plurality of the localization data sources to be combined to output a vehicle location can be selected.

Vehicle localization

In a vehicle computer, a trigger may be received to provide localization data to a first vehicle application that is one of a plurality of vehicle applications in a vehicle that receive the localization data. Based on the trigger, resources can be allocated to a first data container that provides the localization data in a first format specified for the application, and that is one of a plurality of data containers included in the system. The localization data can be provided in the first format to the first vehicle application upon receiving a location request from the application.

Position enhancement for vehicle positioning is provided. Vehicle-to-everything (V2X) messages are received from a roadside unit (RSU) to an onboard unit (OBU) of a vehicle via a transceiver of the vehicle, the V2X messages indicating a location of the RSU. Image sensors of the vehicle are utilized to capture sensor data of the RSU. A current position of the vehicle is updated to a corrected current position of the vehicle based the RSU as shown in the sensor data and the location of the RSU indicated in the V2X messages.

Smart tolling for vehicles is provided. A toll advertisement message (TAM) is received by a vehicle, broadcast from a road-side unit (RSU) via V2X communication, the TAM defining a plurality of toll road tariff data elements, each of the toll road tariff data elements specifying a set of tolling factors indexed by a unique toll context identifier. Roadway usage of the vehicle is determined. A charge for the roadway usage is determined according to the set of tolling factors of the TAM. A toll usage message (TUM) is sent via the V2X communication, the TUM indicating, to the RSU, the tariff for the roadway usage of the vehicle.

Toll advertisement message road topologies

Exemplary embodiments described in this disclosure are generally directed to vehicle detection systems and methods. In one exemplary embodiment, a vehicle detection system that is provided in a first vehicle receives a map generated by a vehicle detection system of a second vehicle. The map, which can be a cardinal map, for example, indicates a third vehicle that is detected by the vehicle detection system of the second vehicle and is undetectable by the first vehicle due to various reasons. For example, the first vehicle may fail to detect the third vehicle due to signal blocking caused by an intervening vehicle located between the first vehicle and the third vehicle, or due to the loss of radio-frequency (RF) signal reception by the vehicle detection system in the first vehicle. The second vehicle can detect the third vehicle by using radio-frequency (RF) signals and to convey the information to the first vehicle.

Vehicle detection systems and methods

A toll advertisement message is received, via a V2X transceiver of a vehicle, defining a metered zone in which tolls are charged. Input data indicative of a current position of the vehicle with respect to the metered zone is determined. A state machine is utilized to determine tolled roadway usage of the vehicle according to the metered zone and the current position. A toll usage message indicative of the tolled roadway usage is provided via the V2X transceiver.

V2X road usage charging

A toll advertisement message (TAM) broadcast from a roadside unit (RSU) is received by a vehicle via V2X communication, the TAM indicating geographic locations of lanes of a roadway for which tolls are due and cost information for traversing the lanes of the roadway. A heading of the vehicle is determined in relation to a TAM reference point indicating a geographic location of a toll gantry. A toll zone boundary region for the vehicle is identified by filtering the geographic locations of the lanes in the TAM to include only those lanes in a travel direction consistent with the heading. A lane straddling algorithm is utilized to identify, for each of the lanes in the travel direction, a respective percentage within each lane that the vehicle is traveling. A tolling usage message (TUM) is sent via the V2X communication, indicating to the RSU the percentage lane usage of the vehicle.

Smart toll application determining for various toll applications using V2X communications

An on-board unit of a vehicle includes first and second transceivers. A processor of the vehicle monitors transmissions received from the first and second transceivers, receives an incoming message sent to the processor from the first transceiver, the incoming message being designated for distribution to roadway participants, identifies based on the monitored transmissions whether the second transceiver is in communication with devices of roadway participants available to receive outgoing messages, and if so, construct an outgoing message based on the incoming message and send the outgoing message via the second transceiver, and monitors vehicle network bus traffic to identify a current speed of the vehicle, and responsive to the vehicle moving at least a threshold speed, construct and send vehicle-information outgoing messages including roadway observations of the vehicle, using the first transceiver and the second transceiver, the vehicle-information outgoing messages being designated for distribution to the roadway participants.

Method and apparatus for bridging and optimizing V2X networks in vehicles

A transportation system comprising a logic node configured to determine an optimized rendezvous location for a vehicle in an area based at least in part on traffic data associated with a plurality of vehicles in the area; and a communication element adapted to communicate the optimized rendezvous location to the vehicle.

Enhanced transportation routing for communication with devices of vehicles and passengers

A request is received, from an onboard unit of a vehicle to a roadside unit in control of a gate protecting a gated area, for access rights to the gated area. Responsive to determining that the vehicle is authorized to enter, vehicle localization is performed to confirm that the vehicle has an unobstructed path to the gate. The vehicle localization is performed using one or more approaches. Responsive to confirming that the vehicle has an unobstructed path to the gate, direct the gate to open to allow the vehicle to proceed.

Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on echo times of an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. Engine power is limited differently based on distinct coolant level states determined based on a change in level of coolant in the reservoir over a duration.

Method and system for engine cooling system control

Exemplary embodiments described in this disclosure are generally directed to systems and methods for displaying visual content in an automobile. In an exemplary implementation, an onboard computer of an automobile receives wireless signals from a roadside unit located near the traffic intersection. The wireless signals provide information about how much time is remaining before a traffic light turns from a red state to a green state. The onboard computer uses this information to display visual content on an infotainment system in the automobile as long as the automobile is in a stopped condition. The onboard computer stops displaying the content before the traffic light turns green. In one case, the wireless signals transmitted from the roadside unit include a Signal Phase and Timing (SPaT) signal and a traffic intersection map that provides details about a topography of the traffic intersection.
