Abstract: 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.

Abstract: Systems, methods, and computer-readable media are disclosed for network node communication using dynamically configurable interaction modes. Example methods may include identify a first triggering event associated with an agent, the agent comprising a vehicle or a user; determine a first mode for the agent based on the first triggering event; exchange a first communication with other agents over a network, wherein the first communication is based on the first mode and comprises a first action to be taken by the other agents; determine a second mode for the agent based on a second triggering event; and exchange a second communication with the other agents over the network, wherein the second communication is based on the second mode and comprises a second action to be taken by the other agents, and wherein the second mode and the first mode are of different types.

Abstract: Vehicle road usage is monitored via vehicle-to-everything (V2X) communication. From each of a plurality of vehicles via one or more RSUs communicating with vehicles using V2X communication, anonymized data is received indicating routing of the respective vehicle along roadways over time and location. From each of the plurality of vehicles via the one or more RSUs, non-anonymized usage amounts are received indicative of a cost incurred by the respective vehicle for overall usage of the roadway by the respective vehicle, the usage amounts being computed by the respective vehicle according to usage metrics broadcast by the one or more RSUs. Roadway areas of high roadway usage are identified according to the anonymized data. The usage metrics are updated to incentivize alternative routes to routes traversing the roadway areas of high roadway usage. The usage metrics, as updated, are broadcast for receipt by the plurality of vehicles.

Abstract: 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.

Abstract: 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.

Abstract: Method and apparatus are disclosed for mitigating channel congestion in inter-vehicle communication. An example vehicle comprising includes a wireless communication module and an intervehicle communication module. The intervehicle communication module forms a communication group with other vehicles based on vehicle characteristics. The intervehicle communication module also monitors network congestion of a first channel. Additionally, in response to detecting network congestion on the first channel, the intervehicle communication module broadcasts a switch message to instruct the other vehicles to switch to a second channel, and broadcasts safety messages on the second channel.

Abstract: A computer-implemented method includes determining a path to a destination passing through a plurality of wireless access coverage areas corresponding to wireless networks selected based on the wireless networks meeting user defined network parameters, such that a projected amount of necessary data can be transferred as a vehicle travels the path. The method also includes determining an access plan for connecting the vehicle to the wireless networks as the vehicle travels along the path. The method further includes using the path as a navigation route and executing the access plan to connect the vehicle to the wireless networks according to the access plan.
