BACKGROUND

Field

Certain aspects of the present disclosure generally relate to connected vehicle applications and, more particularly, to a system and method of partial sensor data sharing for connected vehicles.

Background

Connected vehicle applications enable support for intelligent transportation systems (ITS). In general, ITS are advanced applications integrating telecommunications, electronics, and information technologies to support connected vehicles. ITS applications apply transport engineering to plan, design, operate, maintain, and manage transport systems of a connected vehicle. In particular, these ITS applications provide improved user information and increased safety by coordinating “smarter” use of transport networks.

Connected vehicle applications support vehicle-to-vehicle (V2V) communications and vehicle-to-infrastructure (V2I) with wireless technology. For example V2V communications use wireless signals to send information back and forth between other connected vehicles (e.g., location, speed, and/or direction). Conversely, V2I communications involve vehicle-to-infrastructure communications (e.g., road signs or traffic signals), generally involving vehicle safety issues. For example, V2I communications may request traffic information from a traffic management system to determine best possible routes. V2V and V2I applications for connected vehicles dramatically increase automotive safety by transforming vehicle operation.

The amount of sensor (radars, cameras, LiDAR, etc.) data generated by connected vehicle applications is growing exponentially due to an increased number of connected vehicles. This data may be shared with other vehicles (e.g., vehicle-to-vehicle (V2V) communication) and/or the infrastructure network (vehicle-to-infrastructure (V2I) communication). Unfortunately, the capacity of the communication links is limited. In addition, sharing a huge amount of data is costly and will cause channel congestion in the wireless network, which in turn increases the transmission time (or delay), and some data might even be lost.

SUMMARY

A method of partial sensor data sharing is described. The method includes defining an area of interest (AoI) based on a traffic topology and state information of a selected sender vehicle. The method also includes transmitting the area of interest to the selected sender vehicle. The method further includes sharing, by the selected sender vehicle, a sensor data corresponding to the area of interest when the area of interest is within a sensor coverage area of the selected sender vehicle.

A system for partial sensor data sharing from a selected sender vehicle is described. The system includes a sensor module. The system also includes a mobile unit communication module coupled to the sensor module. The system further includes a controller configured to share sensor data corresponding to a received area of interest through the mobile unit communication module. The controller is configured to share the sensor data when the received area of interest is within a sensor coverage area of the sensor module of the selected sender vehicle.

A non-transitory computer-readable medium having program code recorded thereon for partial sensor data sharing is described. The program code is executed by a processor and includes program code to define an area of interest (AoI) based on a traffic topology and state information of a selected sender vehicle. The non-transitory computer-readable medium also includes program code to transmit the area of interest to the selected sender vehicle. The non-transitory computer-readable medium further includes program code to share, by the selected sender vehicle, a sensor data corresponding to the area of interest when the area of interest is within a sensor coverage area of the selected sender vehicle.

This has outlined, rather broadly, the features and technical advantages of the present disclosure in order that the detailed description that follows may be better understood. Additional features and advantages of the present disclosure will be described below. It should be appreciated by those skilled in the art that the present disclosure may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present disclosure. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the teachings of the present disclosure as set forth in the appended claims. The novel features, which are believed to be characteristic of the present disclosure, both as to its organization and method of operation, together with further objects and advantages, will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present disclosure.
