Abstract

Provided are an apparatus and a method of controlling automatic driving of a vehicle, which adjust an operation mode of a map-supported system to a limited operation, a normal operation, and an emergent operation according to a driving situation for a safe operation of a map-supported driving assistant or automatic driving system.

Claims

1. An apparatus for controlling automatic driving of a vehicle, comprising:

an input unit configured to receive a command related to control of automatic driving of a vehicle from a driver;

an interlinked control determination unit configured to determine whether the control of the automatic driving of the vehicle based on road information is available when the command is input; and

an automatic driving control unit configured to control the automatic driving of the vehicle by using a vehicle sensor and a navigation device when it is determined that the control of the automatic driving of the vehicle based on the road information is available, and control the automatic driving of the vehicle by using only the vehicle sensor when it is determined that the control of the automatic driving of the vehicle based on the road information is unavailable.

2. The apparatus of claim 1, wherein the interlinked control determination unit determines whether the control of the automatic driving of the vehicle based on the road information is available by using any one of whether information is received from the GPS, whether the vehicle enters a service area, and whether there is a driver'"'"'s request.

3. The apparatus of claim 1, wherein when it is determined that a predetermined time elapses, the vehicle travels a predetermined distance, or an inter-vehicular distance with a preceding vehicle is equal to or larger than a reference distance, the automatic driving control unit controls the automatic driving of the vehicle by using the vehicle sensor and the navigation device.

4. The apparatus of claim 1, further comprising:

an automatic control releasing unit configured to output an alert message when at least one element of dangerous situation information among non-available GPS reception, service area deviation, an operation of a steering device by the driver, and preceding obstacle detection is detected, and release the control of the automatic driving of the vehicle when the dangerous situation information is detected even after a predetermined time elapses.

5. The apparatus of claim 1, further comprising:

an automatic control change unit configured to output an alert message when at least one element of cautious situation information among driving route initialization, driving route re-search, lane deviation, and uncontrollable inter-vehicular distance is detected, and control the automatic driving of the vehicle by using only the vehicle sensor except for the navigation device when the cautious situation information is detected even after a predetermined time elapses.

6. A method of controlling automatic driving of a vehicle, comprising:

receiving a command related to control of automatic driving of a vehicle from a driver;

determining whether the control of the automatic driving of the vehicle based on road information is available when the command is input; and

controlling the automatic driving of the vehicle by using a vehicle sensor and a navigation device when it is determined that the control of the automatic driving of the vehicle based on the road information is available, and controlling the automatic driving of the vehicle by using only the vehicle sensor when it is determined that the control of the automatic driving of the vehicle based on the road information is unavailable.

7. The method of claim 6, wherein the determining includes determining whether the control of the automatic driving of the vehicle based on the road information is available by using any one of whether information is received from the GPS, whether the vehicle enters a service area, and whether there is a driver'"'"'s request.

8. The method of claim 6, wherein the controlling includes controlling the automatic driving of the vehicle by using the vehicle sensor and the navigation device when it is determined that a predetermined time elapses, the vehicle travels a predetermined distance, or an inter-vehicular distance with a preceding vehicle is equal to or larger than a reference distance.

9. The method of claim 6, further comprising:

outputting an alert message when at least one element of dangerous situation information among non-available GPS reception, service area deviation, an operation of a steering device by the driver, and preceding obstacle detection is detected, and releasing the control of the automatic driving of the vehicle when the dangerous situation information is detected even after a predetermined time elapses.

10. The apparatus of claim 6, further comprising:

outputting an alert message when at least one element of cautious situation information among driving route initialization, driving route re-search, lane deviation, and uncontrollable inter-vehicular distance is detected, and controlling the automatic driving of the vehicle by using only the vehicle sensor except for the navigation device when the cautious situation information is detected even after a predetermined time elapses.
