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: 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.

Abstract: 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.

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: 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.
