CPC Class H04W

A warning system for warning pedestrians and other road users prior to a collision with a charging cable for an electric automobile. Charging cables run from a power source to a vehicle. The vehicle is charged using a charging cable. The vehicle being charged has the information that it is currently charging. It also has sensors that can identify the course of the cable, depending on the resolution and orientation of the sensors. This can be implemented using image processing algorithms or machine learning. The parked vehicle can also detect other road users by means of the onboard sensor system. If an impending collision between the road user and the charging cable is determined from these data, the road user is warned, using any of acoustic warning, or visual warning.

In a self-vehicle with V2X communication capability and with an enhanced ADAS, a method for warning nearby road-users at risk using exterior vehicle lights, the method comprising by the enhanced ADAS, analyzing the behavior of a non-V2X connected road-user ahead and/or a non-V2X connected road-user behind the self-vehicle using inputs from at least one sensor of the self-vehicle and from V2X communications received in the self-vehicle, determining from the analysis that the non-V2X connected road-user ahead and/or the non-V2X connected road-user behind poses a risk to another road-user, and warning the non-V2X connected road-user ahead and/or the non-V2X connected road-user behind that it poses the risk using a special lighting pattern displayed on an exterior part of the self-vehicle.

A device and method are configured to provide a notification of an occurrence of a vehicle accident when an airbag is deployed. The device acquires an intensity of a signal received from a server for at least one communication medium, transmits a notification including information on an occurrence of an accident to the server when an airbag of a vehicle is deployed, and retransmits the notification based on the intensity of the received signal when the transmission of the notification has failed. When the transmission of the notification including the information on the occurrence of the accident has failed because a wireless network communication is not operating correctly, wireless communication connection may be reattempted the appropriate number of times to increase a success rate.

An information processing device comprising a processor, the processor being configured to: in a case in which a door of a vehicle is locked, determine whether or not a terminal that operates as an electronic key is located in the vehicle; and in a case in which the terminal is determined to be located in the vehicle, perform control to restrict at least a subset of functions, among functions of the vehicle that are controlled in accordance with communications with the terminal, based on a lock trigger causing the locking of the door of the vehicle.

The present radio system transmits an electromagnetic signal to nearby devices requesting the device respond. The radio system also receives responses to the electromagnetic signal from the nearby devices. Based on the radio technology used, the signaling of the transmitted electromagnetic signal may be varied. For example, the transmitted electromagnetic signal may be a Bluetooth, 802.11, or other radio signal. A device that received the signal from the radio unit may transmit a response signal with the same radio technology. However, in some instances, the radio technology used for communication may operate on several radio (e.g., frequency) channels. Both the transmitter and receiver must operate on the same channel at the same time in order to communicate. Thus, it may be desirable to transmit the electromagnetic signal on more than one channel at the same time, in order to increase the chances that a nearby device responds.

Described is a two-level optimal path planning process for autonomous tractor-trailer trucks which incorporates offline planning, online planning, and utilizing online estimation and perception results for adapting a planned path to real-world changes in the driving environment. In one aspect, a method of navigating an autonomous vehicle includes determining, by an online server, a current vehicle state of the autonomous vehicle in a mapped driving area. The method includes receiving, by the online server from an offline path library, a path for the autonomous driving vehicle through the mapped driving area from the current vehicle state to a destination vehicle state, and receiving fixed and moving obstacle information. The method includes adjusting the path to generate an optimized path that avoids the fixed and moving obstacles and ends at a targeted final vehicle state, and navigating the autonomous vehicle based on the optimized path.
