This application relates to a system or method for effectively providing an emergency vehicle alert to other vehicles by dynamically configuring a size, shape and direction of a geofence for the emergency vehicle according to an intent of the emergency vehicle operator to assist the emergency vehicle to safely pass the other vehicles and to prevent vehicle or officer strikes from behind when stopped on a roadside.
When emergency situations such as disasters, car accidents, crimes, etc. take place, it is not only critical to send emergency responders to emergency scenes promptly and efficiently to provide rescue efforts to the people involved in the emergency event, but it is also important to guarantee the safety of emergency vehicles (EVs) responding to the emergency scene.
Widely used means to guarantee the safety of EVs includes providing direct emergency vehicle alerts based on conventional audio or visual signaling devices such as flashing lights, sirens and/or horns. However, these conventional signaling devices may not be adequate, or may provide unnecessary alerts to vehicles which are not even on roads that the EV can travel. These alerts may also easily be ignored by people, or go unnoticed by people with hearing impairments or by distracted drivers.
However, no prior work has been made on determining an appropriate size or shape of the EV geofence in consideration of an intent with which the EV is operated.
權利要求
What is claimed is:1. A system for providing an emergency vehicle (EV) alert, comprising:a plurality of sensors configured to collect EV-related data, including data related to at least an operation status and an occupancy status of an EV; a processor configured to generate a geofence for the EV by varying a size or shape of the geofence depending on a working mode of the EV, a determined intent associated with the EV, and the EV-related data; and a transmitter configured to transmit the generated geofence, wherein the working mode includes a non-emergency normal mode and two or more emergency modes having different degrees of emergency from one another, and wherein the processor is configured to vary the size and shape of the geofence based on the degree of emergency when the working mode is one of the two or more emergency modes; and wherein the intent includes an emergency action or mission assigned to the EV and is determined based on whether the EV is mobile or immobile. 2. The system of claim 1 , further comprising another vehicle, wherein another processor associated with the another vehicle is configured to:receive the geofence; determine a location of the another vehicle with respect to the geofence; and perform one or more alert actions based on the determined location of the another vehicle with respect to the received geofence. 3. The system of claim 1 , wherein the processor is further configured to determine the working mode of the EV based on a selection input by an operator or program instructions stored in memory and executable by the processor, andwherein the program instructions, when executed by the processor, determine the working mode based on information on an emergency situation received over a communication network. 4. The system of claim 3 , wherein the processor and the memory storing the program instructions are implemented using a machine learning system. 5. The system of claim 1 , further comprising an input interface configured to:receive the selection input corresponding to one of the normal mode and the two or more emergency modes; and transmit the selection input to the processor. 6. The system of claim 5 , wherein the input interface comprises one or more selection menus associated with the emergency modes. 7. The system of claim 1 , wherein the processor is further configured to increase the size of the geofence when the working mode is changed from the normal mode to one of the two or more emergency modes. 8. The system of claim 1 , wherein the processor is further configured to increase the size of the geofence when the working mode is changed from one of the two or more emergency modes having a first degree of emergency to another of the two or more emergency modes having a second degree of emergency higher than the first degree of emergency. 9. The system of claim 1 , wherein the processor and the transmitter are in the vicinity of or included in the EV. 10. The system of claim 1 , wherein the processor and the transmitter are in the vicinity of or included in a management server remotely located from the EV. 11. The system of claim 1 , further comprising:increasing, by the processor, the size of the geofence when the working mode is changed from one of the two or more emergency modes having a first degree of emergency to another of the two or more emergency modes having a second degree of emergency higher than the first degree of emergency. 12. The system of claim 1 , wherein at least one of the plurality of sensors is a door sensor or a seat sensor. 13. A method for providing an emergency vehicle (EV) alert, comprising:collecting, with a plurality of sensors, EV-related data including data related to at least an operation status and an occupancy status of an EV; determining an intent associated with the EV, wherein the intent includes an emergency action or mission assigned to the EV and is based on whether the EV is mobile or immobile; generating, by a processor, a geofence by varying a size or shape of the geofence depending on a working mode of an EV, the determined intent, and the EV-related data; transmitting, by a transmitter, the generated geofence; wherein the working mode includes a non-emergency normal mode and two or more emergency modes having different degrees of emergency from one another, and wherein the processor is configured to vary the size and shape of the geofence based on the degree of emergency when the working mode is one of the two or more emergency modes. 14. The method of claim 13 , further comprising:receiving, by another processor associated with another vehicle, the geofence; determining, by the another processor, a location of the another vehicle with respect to the received geofence; and performing, by the another processor, one or more alert actions based on the determined location of the another vehicle with respect to the received geofence. 15. The method of claim 13 , further comprising:determining the working mode of the EV based on a selection input by an operator or program instructions stored in memory and executable by the processor, wherein the program instructions, when executed by the processor, determine the working mode based on information on an emergency situation received over a communication network. 16. The method of claim 13 , further comprising:receiving the selection input corresponding to one of the normal mode and the two or more emergency modes using an input interface; and transmitting the selection input to the processor. 17. The method of claim 13 , further comprising:increasing, by the processor, the size of the geofence when the working mode is changed from the normal mode to one of the emergency modes. 18. The method of claim 13 , wherein at least one of the plurality of sensors is a door sensor or a seat sensor. 19. A non-transitory computer-readable storage medium having computer readable program instructions,the computer readable program instructions read and executed by at least one processor for performing a method for providing an emergency vehicle (EV), comprising:receiving, from a plurality of sensors, EV-related data including date related to at least an operation status and an occupancy status of the EV; generating a geofence by varying a size or shape of the geofence depending on a working mode of the EV, a determined intent associated with the EV, and the EV-related data; and transmitting the generated geofence; wherein the working mode includes a non-emergency normal mode and two or more emergency modes having different degrees of emergency from one another, and wherein the processor is configured to vary the size and shape of the geofence based on the degree of emergency when the working mode is one of the two or more emergency modes; and wherein the intent includes an emergency action or mission assigned to the EV and is determined based on whether the EV is mobile or immobile. 20.
