Abstract

A vehicle is capable of providing an immediate notification that an emergency has occurred by transmitting a trigger signal to an emergency call unit even when only a few of a plurality of airbag deployment conditions are satisfied. The vehicle is further capable of improving reliability of the emergency call by performing an additional check to confirm via voice recognition whether an emergency has actually occurred when a few of the plurality of airbag deployment conditions are satisfied.

First claim

What is claimed is:

1. A vehicle comprising:
a detection unit configured to detect a collision of the vehicle;
an emergency call module configured to transmit an emergency call when a trigger signal is input;
an airbag module comprising at least one airbag and configured to supply gas to the at least one airbag when the trigger signal is input;
an airbag controller configured to determine an airbag deployment condition based on an output of the detection unit and transmit the trigger signal to the airbag module when the airbag deployment condition is satisfied; and
an emergency call controller configured to determine the airbag deployment condition based on the output of the detection unit and transmit the trigger signal to the emergency call unit when the airbag deployment condition is satisfied, wherein the airbag deployment condition is determined by applying a different standard from the airbag controller, wherein:
the airbag controller determines that the airbag deployment condition is satisfied when a result calculated based on the output of the detection unit is equal to or greater than a first reference value; and
the emergency call controller determines that the airbag deployment condition is satisfied when the result calculated based on the output of the detection unit is equal to or greater than a second reference value, which is lower than the first reference value.

2. The vehicle according to claim 1 , further comprising:
a voice recognition module configured to recognize a user's voice,
wherein the airbag controller activates the voice recognition module when the airbag deployment condition is satisfied.

3. A vehicle comprising:
a detection unit configured to detect a collision of the vehicle;
an emergency call module configured to transmit an emergency call when a trigger signal is input
an airbag module comprising at least one airbag and configured to supply gas to the at least one airbag when the trigger signal is input
an airbag controller configured to determine an airbag deployment condition based on an output of the detection unit and transmit the trigger signal to the airbag module when the airbag deployment condition is satisfied; and
an emergency call controller configured to determine the airbag deployment condition based on the output of the detection unit and transmit the trigger signal to the emergency call unit when the airbag deployment condition is satisfied, wherein the airbag deployment condition is determined by applying a different standard from the airbag controller, wherein:
the airbag controller determines that the airbag deployment condition is satisfied when the result calculated based on the output of the detection unit is equal to or less than the first reference value; and
the emergency call controller determines that the airbag deployment condition is satisfied when the result calculated based on the output of the detection unit is equal to or less than the second reference value, which is higher than the first reference value.

4. The vehicle according to claim 3 , further comprising:
a voice recognition module configured to recognize a user's voice,
wherein the airbag controller activates the voice recognition module when the airbag deployment condition is satisfied.

5. A control method for a vehicle, the method comprising the steps of:
determining whether an airbag deployment condition is satisfied by applying a first reference value and transmitting a trigger signal to an airbag module when the airbag deployment condition is satisfied; and
determining whether the airbag deployment condition is satisfied by applying a second reference value which is different from the first reference value and transmitting the trigger signal to the emergency call unit when the airbag deployment condition is satisfied, wherein:
the step of determining whether the airbag deployment condition is satisfied by applying the first reference value comprises determining that the airbag deployment condition is satisfied when a result calculated based on an output of at least one sensor to detect a collision of the vehicle is equal to or greater than the first reference value, and
the step of determining whether the airbag deployment condition is satisfied by applying the second reference value comprises determining that the airbag deployment condition is satisfied when the result calculated based on the output of the at least one sensor is equal to or greater than the second reference value, which is lower than the first reference value.

6. The method according to claim 5 , further comprising:
recognizing a user's voice using a voice recognition module; and
activating the voice recognition module when the airbag deployment condition is satisfied.

7. A control method for a vehicle, the method comprising the steps of:
determining whether an airbag deployment condition is satisfied by applying a first reference value and transmitting a trigger signal to an airbag module when the airbag deployment condition is satisfied; and
determining whether the airbag deployment condition is satisfied by applying a second reference value which is different from the first reference value and transmitting the trigger signal to the emergency call unit when the airbag deployment condition is satisfied, wherein:
the step of determining whether the airbag deployment condition is satisfied by applying the first reference value comprises determining that the airbag deployment condition is satisfied when the result calculated based on the output of the at least one sensor to detect a collision of the vehicle is equal to or less than the first reference value, and
the step of determining whether the airbag deployment condition is satisfied by applying the second reference value comprises determining that the airbag deployment condition is satisfied when the result calculated based on the output of the at least one sensor is equal to or less than the second reference value, which is higher than the first reference value.

8. The method according to claim 7 , further comprising:
recognizing a user's voice using a voice recognition module; and
activating the voice recognition module when the airbag deployment condition is satisfied.
