Abstract

A vehicle safety support apparatus includes: a driver monitoring sensor configured to monitor a driver; an external environment monitoring sensor configured to monitor an external environment of a vehicle; and at least one processor configured to: determine whether the vehicle is in an immediate hazard situation based on data acquired from the driver monitoring sensor and the external environment monitoring sensor; determine, in response to determining that the vehicle is in the immediate hazard situation, whether to perform a recovery maneuver or a rescue maneuver based on the data acquired from the driver monitoring sensor and the external environment monitoring sensor to get out of the immediate hazard situation; and perform, in response to determining to perform the rescue maneuver, autonomous driving to move the vehicle to a safe area by taking over a driving control from the driver.

First claim

What is claimed is:

1. A vehicle safety support apparatus comprising:
a driver monitoring sensor configured to monitor a driver;
an external environment monitoring sensor configured to monitor an external environment of a vehicle; and
at least one processor configured to:
determine whether the vehicle is in an immediate hazard situation based on data acquired from the driver monitoring sensor and the external environment monitoring sensor;
determine, in response to determining that the vehicle is in the immediate hazard situation, whether to perform a recovery maneuver or a rescue maneuver based on the data acquired from the driver monitoring sensor and the external environment monitoring sensor to get out of the immediate hazard situation;
perform, in response to determining to perform the rescue maneuver, autonomous driving to move the vehicle to a safe area by taking over a driving control from the driver; and
a driver input filtering unit configured to filter a vehicle control input by the driver,
wherein the at least one processor is configured to control the driver input filtering unit to block the vehicle control input from the driver in response to determining to perform the rescue maneuver.

2. The vehicle safety support apparatus of claim 1 , wherein the at least one processor is configured to:
estimate an availability of the driver based on the data acquired from the driver monitoring sensor;
estimate a traffic hazard based on the data acquired from the external environment monitoring sensor; and
determine to take over the driving control based on the estimated availability of the driver and traffic hazard.

3. The vehicle safety support apparatus of claim 1 , wherein the at least one processor is configured to perform the rescue maneuver in response to the vehicle is in immediate hazard situation and there is no response by the driver.

4. The vehicle safety support apparatus of claim 1 , wherein the recovery maneuver comprises at least one of: returning the vehicle to original lane; emergency braking to avoid colliding into another vehicle; and running through an intersection.

5. The vehicle safety support apparatus of claim 1 , wherein the at least one processor is configured to operate a hazard lamp of the vehicle in response to performing the autonomous driving.

6. The vehicle safety support apparatus of claim 1 , wherein the at least one processor is configured to transmit a signal requesting for emergency assistance through a communication unit, in response to performing autonomous driving to move the vehicle to the safe area.

7. The vehicle safety support apparatus of claim 1 , wherein the at least one processor is configured to perform the autonomous driving based on the data acquired from the external environment monitoring sensor.

8. The vehicle safety support apparatus of claim 1 , wherein the driver monitoring sensor comprises: at least one interior camera for filming the driver; a steering wheel angle sensor; an accelerator pedal sensor; and a brake pedal sensor.

9. The vehicle safety support apparatus of claim 1 , wherein the external environment monitoring sensor comprises: at least one exterior camera; radar; and ultrasonic sensor, configured to detect an outside environment of the vehicle.

10. A vehicle safety support method comprising:
monitoring, using sensors, a driver and an external environment of a vehicle;
estimating, by at least one processor, an availability of a driver and traffic hazard based on data acquired from monitoring the driver and the external environment;
determining whether the vehicle is in an immediate hazard situation based on the estimated availability of the driver and traffic hazard;
determining, by the at least one processor in response to determining that the vehicle is in the immediate hazard situation, whether to perform a recovery maneuver or a rescue maneuver based on the estimated availability of the driver and traffic hazard to get out of the immediate hazard situation;
performing, by the at least one processor in response to determining to perform the rescue maneuver, autonomous driving to move the vehicle to a safe area, by taking over a driving control from the driver; and
blocking, by the at least one processor, a vehicle control input from the driver, in response to determining to perform the rescue maneuver.

11. The vehicle safety support method of claim 10 , further comprising:
transmitting, by the at least one processor, a signal for requesting an emergency assistance through a communication unit, in response to the performing of the autonomous driving to move the vehicle to the safe area.

12. The vehicle safety support method of claim 10 , wherein the monitoring, using the sensors, of the driver and the external environment comprises:
monitoring at least one of physical feature, posture, and control intention of the driver.

13. The vehicle safety support method of claim 10 , wherein the monitoring of the driver and the external environment, using the sensors, comprises:
monitoring at least one of road and traffic environment outside of the vehicle.

14. The vehicle safety support method of claim 10 , wherein the recovery maneuver comprises at least one of: returning the vehicle to original lane; emergency braking to avoid colliding into another vehicle; and running through an intersection.
