Driving assistance apparatus and driving assistance method
Disclosed herein are a driving assistance apparatus and a driving assistance method. The present disclosure is directed to allowing a driver to quickly and preferably respond to an emergency situation that is not found due to a sensor recognition error during autonomous driving of a vehicle. To this end, a driving assistance method according to the present disclosure includes monitoring a change in driving route of another vehicle traveling in front of a host vehicle through a camera of the host vehicle, receiving a guide route for autonomous driving through vehicle to everything (V2X) communication, and upon the received guide route not matching the driving route of the another vehicle, decelerating the host vehicle to a preset speed so that the host vehicle slowly travels along the guide route.
1. A driving assistance method comprising:
monitoring a change in driving route of another vehicle traveling in front of a host vehicle through a camera of the host vehicle;
receiving a guide route for autonomous driving through vehicle-to-everything (V2X) communication;
decelerating the host vehicle to a preset speed so that the host vehicle slowly travels along the guide route, based on the received guide route not matching the driving route of the other vehicle;
outputting a warning message to prepare for an emergency situation ahead of the host vehicle, based on the received guide route not matching the driving route of the other vehicle; and
increasing a speed of the host vehicle to a speed before decelerating so that the host vehicle travels along the guide route, based on receiving a driver's confirmation of the warning message.
2. The driving assistance method of claim 1 , further comprising maintaining a slow moving state along the guide route, based on not receiving the driver's confirmation of the warning message.
3. The driving assistance method of claim 1 , further comprising driving the host vehicle along the same route as the other vehicle in front, based on the received guide route matching the driving route of the other vehicle.
4. The driving assistance method of claim 3 , further comprising receiving route information from the other vehicle in front through the V2X communication to drive the host vehicle along the same route as the other vehicle in front.
5. The driving assistance method of claim 1 , further comprising driving the host vehicle along the received guide route, based on the other vehicle not being present in front of the host vehicle.
6. The driving assistance method of claim 1 , wherein the other vehicle traveling in front of the host vehicle is another vehicle traveling in the same lane as a lane in which the host vehicle drives.
7. A driving assistance apparatus comprising:
a camera provided to photograph surroundings of a host vehicle; and
a processor configured to:
monitor a change in driving route of another vehicle traveling in front of the host vehicle through the camera,
receive a guide route for autonomous driving through vehicle-to-everything (V2X) communication,
perform control such that the host vehicle decelerates to a preset speed so that the host vehicle slowly travels along the guide route, based on the received guide route not matching the driving route of the other vehicle,
perform control such that a warning message is output to prepare for an emergency situation ahead of the host vehicle, based on the received guide route not matching the driving route of the other vehicle, and
perform control such that a speed of the host vehicle increases to a speed before decelerating so that the host vehicle travels along the guide route, based on a driver's confirmation of the warning message being received.
8. The driving assistance apparatus of claim 7 , wherein the processor further performs control such that a slow moving state is maintained along the guide route, based on the driver's confirmation of the warning message not being received.
9. The driving assistance apparatus of claim 7 , wherein the processor further performs control such that the host vehicle travels along the same route as the other vehicle in front, based on the received guide route matching the driving route of the other vehicle.
10. The driving assistance apparatus of claim 9 , wherein the processor further receives route information from the other vehicle in front through the V2X communication to drive the host vehicle along the same route as the other vehicle in front.
11. The driving assistance apparatus of claim 7 , wherein the processor further performs control such that the host vehicle travels along the received guide route, based on the other vehicle not being present in front of the host vehicle.
12. The driving assistance apparatus of claim 7 , wherein the other vehicle traveling in front of the host vehicle is another vehicle traveling in the same lane as a lane in which the host vehicle drives.
13. A driving assistance apparatus comprising:
a camera provided to photograph surroundings of a host vehicle; and
a processor configured to:
monitor a change in driving route of another vehicle traveling in front of the host vehicle through the camera,
receive a guide route for autonomous driving through vehicle-to-everything (V2X) communication,
perform control such that the host vehicle decelerates to a preset speed so that the host vehicle slowly travels along the guide route, based on the received guide route not matching the driving route of the other vehicle, and
perform control such that a speed of the host vehicle increases to a speed before decelerating so that the host vehicle travels along the guide route, based on a driver's confirmation of a warning message being received.
