    Abstract: A portable multi-purpose safety triangle includes: a tripod including: a sign unit; and a support unit which supports the sign unit and is configured to be selectively set in one of a folded state and an unfolded state; and a frame including: a frame body having an accommodation space for accommodating the tripod therein; and a frame cap selectively coupled to the frame body. The support unit includes: a first assistant support and a second assistant support that support the sign unit; an elastic member whose both ends are respectively connected to the first assistant support and the second assistant support, the elastic member providing a restoring force to the first assistant support and the second assistant support; and a main support that supports the elastic member. The sign unit includes a flexible material such that the size thereof is changed according to the state of the support unit.

    Abstract: In a vehicle control system, when an occupant visually recognizes a signboard and signboard course information is included in signboard information corresponding to the signboard, the signboard information is displayed on a display device. When the signboard course information out of the signboard information is visually recognized continuously, a control device generates course information based on the signboard course information. The generated course information is output to a vehicle control ECU, and course change processing based on the course information is performed by the vehicle control ECU.

    Abstract: This document describes change detection criteria for updating sensor-based maps. Based on an indication that a registered object is detected near a vehicle, a processor determines differences between features of the registered object and features of a sensor-based reference map. A machine-learned model is trained using self-supervised learning to identify change detections from inputs. This model is executed to determine whether the differences satisfy change detection criteria for updating the sensor-based reference map. If the change detection criteria is satisfied, the processor causes the sensor-based reference map to be updated to reduce the differences, which enables the vehicle to safely operate in an autonomous mode using the updated reference map for navigating the vehicle in proximity to the coordinate location of the registered object. The map can be updated contemporaneously as changes occur in the environment and without hindering performance, thereby enabling real-time awareness to support controls and to improve driving-safety.

    Abstract: Systems, methods, and computer-readable media are provided for wireless sensor networks (WSNs), including vehicle-based WSNs. A road side unit (RSU) includes one or more fixed sensors covering different sectors of a designated coverage area. The RSU uses the sensors to capture sensor data that is representative of objects in the coverage area, tracks objects (e.g., vehicles) in the coverage area, and determines regions in the coverage area that are not adequately covered by the sensors (e.g., “perception gaps”). When the RSU identifies an object that is in or at a perception gap, then the RSU sends a request to that object for sensor data captured by the object's on-board sensors. The RSU obtains the sensor data from the object, and uses the obtained sensor data to complement the knowledge that the RSU (i.e., “filling the peception gaps”). Other embodiments are disclosed and/or claimed.

    Abstract: A method, apparatus and computer program product are provided to determine lane status confidence indicators of lane status predictions such as closures and/or shifting. Lane statuses and corresponding confidence indicators are determined based on probe data, such as probe data collected from vehicle and/or mobile devices traveling along a road segment. Probe data may be partitioned into clusters and compared to partitioned subsets of the probe data. Cluster stability for the segment and corresponding lane status confidence indicators can be determined based on the comparison. Accordingly, determinations of whether to transmit predicted lane statuses to another system, service, and/or user device may be made.

    Abstract: Methods and systems are provided for generating a signal based on the information of the information system and transmitting/broadcasting the signal to the other vehicle. For example, a method includes receiving, by a processor, an indication that an information system of a vehicle is activated and in response to receiving the indication, generating, by the processor, a signal based on the activated information system of the vehicle. The method further includes broadcasting the signal.

    Abstract: Provided are a vehicle, a vehicle monitoring server, a vehicle monitoring system, and a vehicle monitoring method, that can be suitably used in a configuration whereby the vehicle and the vehicle monitoring server communicate in relation to a travel caution region. A first control device in the vehicle sends an entry notification signal to the vehicle monitoring server prior to entry into a travel caution region, if the travel caution region is included in a target route or a target track. The first control device may also send a passage completed signal to the vehicle monitoring server after passing through the travel caution region. A second control device in the vehicle monitoring server performs an error output if, after receiving an entry notification signal from a specified vehicle, a passage completed signal has not been received by a second prescribed point in time.

    Abstract: The invention relates to a method and systems for detection of phase and timing of traffic signal lights and notifying drivers and controlling vehicle subsystems with driver assistance information generated through processing phase and timing information with location, speed and heading of vehicles. Phase and timing information is detected through analyzing data received from sensors installed on the traffic signal lights. Processing the detected traffic signal light phase and timing information with location, heading and speed information of vehicles, drivers can be notified to regulate the speed of vehicles according to the situation of the traffic signal lights. Additionally, providing the communication of adaptive cruise control, start-stop and autonomous driving systems of vehicles with the traffic signal lights, vehicles can be controlled by these systems according to the situation of the traffic signal lights.
