KR-20260064208-A - Remote support system according to autonomous driving operation limitations and method thereof

Abstract

A remote support system for autonomous driving limit situations is provided, comprising a target vehicle performing autonomous driving and a control server that monitors risk situation information received from the target vehicle and determines whether a risk situation exists based on the risk situation information. When a risk situation is determined, the control server transmits a risk minimization operation command to the target vehicle and determines whether the target vehicle is in a risk minimization state. When a risk is determined, the control server transmits safety response information to the occupants of the target vehicle or surrounding vehicles.

Description

Remote support system and method according to autonomous driving operation limitations The present invention relates to a remote support system and method according to autonomous driving limit situations, and in particular to a remote support system and method according to autonomous driving limit situations for ensuring safety in DDT Fallback situations. Autonomous driving technology is attracting attention as a technology capable of increasing traffic efficiency for logistics and delivery services and reducing economic losses resulting from social issues such as traffic accidents. The Society of Automotive Engineers (SAE International) defines an autonomous driving system as hardware and software capable of continuously performing the entire Dynamic Driving Task (DDT), regardless of whether it is limited to a specific Operational Design Domain (ODD). The Dynamic Driving Task includes real-time operational and tactical functions necessary for vehicle operation in road traffic. Currently, vehicle automation functions are classified into six levels, from Lv.0 to Lv.5, based on the combination of driving assistance and autonomous driving functions, and the Automated Driving System (ADS) refers to levels 3 through 5. DDT Fallback refers to a situation in which the operation and behavior of the ADS cannot be safely performed. The National Highway Traffic Safety Administration (NHTSA), through its Automated Driving Systems 2.0 Voluntary Guidance, identified fallback response strategies as a mandatory safety factor and recommends establishing documented processes for this. Automotive manufacturers are establishing fallback response strategies in the development of their ADS. Conventionally, MRC lacked measures to ensure the safety of vehicle occupants in DDT Fallback situations. Furthermore, depending on the factors of DDT Fallback, the limitations of ADS capabilities (inability to perform lane changes) and the absence of road structures such as shoulders and safety zones can lead to rear-end collisions and expose vehicles to secondary accidents and disrupt traffic flow when stopping within a lane, potentially causing accidents. Accordingly, technology is required to ensure the safety of autonomous vehicles, vehicle occupants, surrounding vehicles, and road users regarding evacuation and response. FIG. 1 is a block diagram of a remote support system according to one embodiment, based on a limit situation of autonomous driving operation. FIGS. 2 and FIGS. 3 are drawings for explaining the operation of a remote support system according to an autonomous driving limit situation according to one embodiment. FIGS. 4 to 6 are flowcharts of a method for controlling an autonomous driving risk situation according to one embodiment. FIG. 7 is a block diagram of a control server of a remote support system according to one embodiment of an autonomous driving limit situation. Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Furthermore, in order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification are denoted by similar reference numerals. Throughout the specification, when a part is described as "comprising" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. The terms used in the embodiments of the present invention have been selected to be as widely used as possible, taking into account their functions in the invention; however, these terms may vary depending on the intent of those skilled in the art, case law, the emergence of new technologies, etc. Additionally, in specific cases, terms have been arbitrarily selected by the applicant, and in such cases, their meanings will be described in detail in the description of the relevant embodiments.
