Abstract

Provided is a driving assistance device allowing a driver to recognize a path of a vehicle by outputting a location of a vehicle and a location of a target space to the driver, the location of the target space being searched for with respect to the location of the vehicle. The driving assistance device includes: a space searching unit configured to search for a target space around a vehicle with respect to the vehicle; a space information acquisition unit configured to acquire a location of the vehicle and a location of the target space; and an output unit configured to output the location of the vehicle and the location of the target space to a driver, wherein, when an automatic steering function is operated, the output unit updates and outputs a current location of the vehicle on a certain cycle, preferably, in real time until the location of the vehicle matches the location of the target space.

Claims

1. A driving assistance device comprising:

a space searching device configured to search for a target space around a vehicle with respect to the vehicle;

a space information acquisition device configured to acquire a location of the vehicle and a location of the target space;

an obstacle sensing device configured to sense an obstacle around the vehicle; and

an output device configured to output the location of the vehicle and the location of the target space to a driver,

wherein, when an automatic steering function is operated, the output device updates and outputs a current location of the vehicle on a certain cycle, preferably, in real time until the location of the vehicle matches the location of the target space, and

wherein, when the location of the vehicle is not within a preset reference range with respect to the location of the target space and the distance to the obstacle around the vehicle is within the preset reference distance, the space searching device changes the current location of the vehicle into the location of the target space.

2. The driving assistance device according to claim 1, wherein the output device outputs the current location of the vehicle and the location of the target space so as to overlap a top view image displayed on a display screen.

3. The driving assistance device according to claim 1, wherein, when the location of the vehicle is within a preset reference range with respect to the location of the target space, the output device outputs movement completion notification.

4. The driving assistance device according to claim 1, wherein, when the location of the vehicle matches the location of the target space, the output device changes and outputs a color of an indicator indicating the target space on a display screen.

5. The driving assistance device according to claim 1, wherein the space information acquisition device acquires the location of the target space by designating four corner points of the vehicle and connecting the designated four corner points within coordinate values corresponding to a size of the target space.

6. The driving assistance device according to claim 1, wherein the space information acquisition device acquires the current location of the vehicle based on a wheel pulse and a wheel speed caused by a steering angle of the vehicle moved to the target space.

7. The driving assistance device according to claim 1,

wherein the output device additionally outputs an alarm when a distance to the obstacle around the vehicle from the vehicle moved to the target space is within a preset reference distance.

8. A driving assistance device comprising:

a space searching device configured to search for a target space around a vehicle with respect to the vehicle;

a space information acquisition device configured to acquire a location of the vehicle and a location of the target space;

an obstacle sensing device configured to sense an obstacle around the vehicle; and

an output device configured to output the location of the vehicle and the location of the target space to a driver,

wherein, when an automatic steering function is operated, the output device updates and outputs a current location of the vehicle on a certain cycle, preferably, in real time until the location of the vehicle matches the location of the target space,

wherein the space information acquisition device acquires the current location of the vehicle based on a wheel pulse and a wheel speed caused by a steering angle of the vehicle moved to the target space, and

wherein, when the location of the vehicle is not within a preset reference range with respect to the location of the target space and the distance to the obstacle around the vehicle is within the preset reference distance, the space searching device changes the current location of the vehicle into the location of the target space.
