Description

Emergency rescue request notification infotainment system and method thereof The present invention relates to a vehicle emergency rescue request, and more specifically, to an emergency rescue request notification technology using an FM radio data system that enables the transmission of an emergency rescue request message to unspecified radio listeners near an accident using an FM radio data system when a vehicle emergency occurs. With the widespread application of in-vehicle computing technology, technological development for the safety and convenience of passengers, including drivers, is progressing rapidly. To ensure the convenience and safety of vehicle users, there is a growing trend to equip vehicles with various sensors and electronic control units—in other words, electronic components. In particular, active research is being conducted on various devices and systems designed to ensure the safety of vehicle occupants. In Korean published patent 10-2017-0029194 (a device for providing emergency rescue services for a vehicle using a mobile terminal and a vehicle including the same), a technology has been disclosed in which an emergency rescue service providing device mounted on a vehicle determines and detects an emergency situation of the vehicle, transmits emergency situation information to a mobile terminal via a short-range wireless communication method, and the mobile terminal transmits an emergency rescue request message to an external service server via a mobile communication network. In addition, when conventional vehicles detected an emergency situation based on signals such as airbag deployment, a communication modem installed inside the vehicle transmitted an emergency rescue request message containing the vehicle's current location information to an emergency rescue center via a commercial mobile communication network to provide emergency rescue services. However, there was a disadvantage in that, in order to receive conventional emergency rescue services, one had to select an infotainment platform equipped with a communication modem as an option when purchasing the vehicle. In addition, conventionally, there was a problem in that emergency rescue services could not be received after the free trial period for connected car services expired following the purchase of a vehicle equipped with an infotainment platform that includes a communication modem, unless a separate paid service was subscribed to. In addition, conventionally, there was a problem in that emergency rescue services using the mobile communication network could not be used when the mobile communication network was unavailable due to disasters such as natural disasters or fires.
