Apparatus, method, and computer readable medium for displaying vehicle information

1. A method for displaying vehicle information, the method comprising:

setting a driving velocity and an inter-vehicle distance after activating a smart cruise control function;

performing a smart cruise control according to the set driving velocity and the set inter-vehicle distance and displaying smart cruise control-related information in an augmented reality display region located in a front portion of a driver's own vehicle;

comparing an actual inter-vehicle distance between the driver's own vehicle and a nearby vehicle to the set inter-vehicle distance during performance of the smart cruise control;

determining a state in which display information cannot be displayed on the augmented reality display region by one or more figures according to the set inter-vehicle distance when the actual inter-vehicle distance is less than the set inter-vehicle distance;

determining an information displayable region in the augmented reality display region; and

scaling the display information depending on a size of the information displayable region and displaying the scaled display information,

wherein a vertical length of the information displayable region is calculated by subtracting a vertical length of an overlapping region of a nearby vehicle region of a front image and the augmented reality display region, and a vertical length of a region in which nearby vehicle indication information is displayed, from a vertical length of the augmented reality display region.

2. The method according to claim 1 , wherein the determining of the information displayable region includes:

detecting the nearby vehicle region from the front image obtained by a front camera, and

extracting the information displayable region, which is capable of displaying the display information, except for a region corresponding to the nearby vehicle region, and a nearby vehicle indication information display region from the augmented reality display region.

3. The method according to claim 1 , further comprising:

checking whether or not the nearby vehicle is outside of the augmented reality display region when the actual inter-vehicle distance is equal to or greater than the set inter-vehicle distance, and

processing and displaying perspective information for the display information corresponding to the set inter-vehicle distance when the preceding vehicle is outside of the augmented reality display region.

4. The method according to claim 3 , wherein the processing and displaying of the perspective information includes:

measuring driving velocity of the nearby vehicle,

checking whether or not the driving velocity of the nearby vehicle is less than the set driving velocity, and

processing the perspective information for the display information when the driving velocity of the nearby vehicle is less than the set driving velocity.

5. The method according to claim 4 , further comprising stopping the displaying of the display information when the driving velocity of the preceding vehicle is greater than the set driving velocity.

6. The method according to claim 4 , wherein in the processing of the perspective information, the perspective information for the display information is processed based on a vehicle width of the nearby vehicle in a front image obtained by a front camera.

7. The method according to claim 1 , wherein when the actual inter-vehicle distance is equal to the set inter-vehicle distance, color of the display information is changed.
