Abstract

Claims (79)

1 . An emergency call system for a vehicle, comprising:

a call generator provided in the vehicle and configured to, based on a command signal being received, generate an emergency call; and

a controller configured to:

collect emergency data at predetermined time intervals from a starting of the vehicle,

generate a dataset including the emergency data collected for a predetermined period of time, and

transmit, based on the emergency call being generated, the dataset to an emergency rescue server,

wherein, in response to a failure to collect a portion of the emergency data at a measurement time interval, (i) the portion of the emergency data collected at the measurement time interval is deleted, (ii) the portion of the emergency data is replaced with normal emergency data collected at a subsequent measurement time interval, and (iii) the normal emergency data is stored.

2 . The emergency call system of claim 1 , wherein the controller comprises:

an emergency data collector configured to:

collect the emergency data including location information of the vehicle, for the predetermined period of time at each predetermined time interval, and

generate the dataset; and

an emergency call controller configured to transmit, based on the emergency call being generated, the dataset to the emergency rescue server.

3 . The emergency call system of claim 2 , wherein the emergency data collector is configured to:

collect, as the emergency data, at least one of latitude and longitude information, traveling direction information, location accuracy-related information, or an instantaneous speed of the vehicle.

4 . The emergency call system of claim 2 , further comprising:

a data corrector configured to, based on a reliability of the emergency data being low, replace the emergency data with new emergency data or correct the emergency data.

5 . The emergency call system of claim 4 , wherein the data corrector is configured to:

based on global positioning system (GPS) data not being received from a GPS module, (i) correct latitude and longitude information of the vehicle using navigation information received from a navigation system and (ii) store the corrected information.

6 . The emergency call system of claim 4 , wherein the data corrector is configured to:

based on (i) GPS data received from a GPS module being determined to indicate a location where the vehicle is not able to move during the measurement time interval and (ii) a comparison between the GPS data and GPS data collected at a previous measurement time interval, determine a failure of collection of the GPS data.

7 . The emergency call system of claim 2 , wherein the emergency call controller is configured to, based on a state of a head unit of the vehicle entering a sleep state, initialize the dataset by deleting the emergency data in the dataset.

8 . The emergency call system of claim 1 ,

wherein the emergency rescue server configured to receive the dataset and estimate a current location of the vehicle by analyzing a location and a traveling direction of the vehicle based on the dataset,

wherein the emergency rescue server comprises:

an emergency data receiver configured to:

receive the dataset transmitted from the controller,

store the dataset in a memory device, and

verify the emergency data of the dataset, and

a travel trajectory analyzer configured to:

determine a change in a location of the vehicle based on the emergency data,

analyze a travel trajectory of the vehicle during the predetermined period of time, and

estimate the current location of the vehicle.

9 . The emergency call system of claim 8 , wherein the emergency rescue server further comprises:

a map projection analyzer configured to:

project, onto a map, latitude and longitude information of the vehicle during a time period obtained from the dataset, and

estimate the current location of the vehicle upon receiving the emergency call.

10 . The emergency call system of claim 9 , wherein the emergency rescue server further comprises:

an accident occurrence notifier configured to transmit a notification of an accident to nearby vehicles based on the estimated location.

11 . An emergency call method for a vehicle, comprising:

collecting, at predetermined time intervals, emergency data including location information of the vehicle;

generating a dataset including the emergency data collected at the predetermined time intervals for a predetermined period of time;

connecting, by a controller, to a call center upon an occurrence of an emergency call;

transmitting the dataset to an emergency rescue server;

receiving the dataset by emergency rescue server;

storing the dataset in a memory device by emergency rescue server; and

verifying the emergency data in the received dataset; and

determining a change in a location of the vehicle based on the emergency data;

analyzing a travel trajectory of the vehicle during the predetermined period of time;

estimating a current location of the vehicle;

replacing the emergency data with new data or correcting the emergency data; and

storing, based on a reliability of the emergency data being low, the new data or the corrected data,

wherein replacing the emergency data and storing the new data or the corrected data comprises:

in response to a failure to collect a portion of the emergency data at a measurement time interval, (i) deleting the portion of the emergency data collected at the measurement time interval, (ii) replacing the portion of the emergency data with normal emergency data collected at a subsequent measurement time interval, and (iii) storing the normal emergency data.

12 . The emergency call method of claim 11 , wherein replacing the emergency data and storing the new data or the corrected data comprises:

based on global positioning system (GPS) data not received from a GPS module, correcting latitude and longitude information of the vehicle using navigation information received from a navigation system and storing the corrected information.

13 . The emergency call method of claim 11 , wherein replacing the emergency data and storing the new data or the corrected data comprises:

based on (i) GPS data received from a GPS module being determined to indicate a location where the vehicle is not able to move and a comparison between the GPS data and GPS data collected at a previous measurement time interval, determining a failure of collection of the GPS data.

14 . The emergency call method of claim 11 , wherein connecting to the call center comprises:

based on a state of a head unit of the vehicle entering a sleep state, initializing the dataset by deleting the emergency data in the dataset.

15 . The emergency call method of claim 11 , further comprising:

projecting, onto a map, latitude and longitude information of the vehicle during a time period obtained from the dataset; and

estimating the current location of the vehicle upon receiving the emergency call.

16 . The emergency call method of claim 15 , further comprising:

transmitting a notification of an accident to nearby vehicles based on the estimated location.

17 . A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

collecting, at predetermined time intervals, emergency data including location information of a vehicle;

generating a dataset including the emergency data collected at the predetermined time intervals for a predetermined period of time;

connecting, by a controller, to a call center upon an occurrence of an emergency call;

transmitting the dataset to an emergency rescue server;

receiving the dataset by the emergency rescue server;

storing the dataset in a memory device by emergency rescue server; and

verifying the emergency data in the received dataset; and

determining a change in a location of the vehicle based on the emergency data;

analyzing a travel trajectory of the vehicle during the predetermined period of time;

estimating a current location of the vehicle;

replacing the emergency data with new data or correcting the emergency data; and

storing, based on a reliability of the emergency data being low, the new data or the corrected data,

wherein replacing the emergency data and storing the new data or the corrected data comprises:

in response to a failure to collect a portion of the emergency data at a measurement time interval, (i) deleting the portion of the emergency data collected at the measurement time interval, (ii) replacing the portion of the emergency data with normal emergency data collected at a subsequent measurement time interval, and (iii) storing the normal emergency data.
