Parking Assist Method and Apparatus for Vehicle

The present invention relates to a vehicle parking assistance method and apparatus. More particularly, the present invention relates to a vehicle parking assistance method and apparatus for assisting a driver in easily parking by varying the parking method according to the parking type and the distance information with the parking compartment or other vehicles.

Recently, the number of vehicles equipped with a system for assisting the parking of the vehicle so that the driver can park easily has increased.

Such a system for assisting the parking of a vehicle often uses a rear or side monitoring apparatus that displays a rear or side by a rear or side camera and displays it on a monitor next to the driver's seat when the vehicle is reversed or parked.

A system that assists the parking of a vehicle may provide appropriate parking assistance information or perform automatic parking only when the parking space and the parking selection on screen display (OSD) exactly match.

That is, in order for the parking space and the parking selection on-screen display to match exactly, the parking line and the parking section line must match, and the image representing the parking position and the parking position must match exactly to allow proper parking.

However, in the case of a system for assisting the parking of such a vehicle, a novice driver or a female driver has difficulty in accurately matching the parking position with the image representing the parking position.

In addition, since the parking assisting system of a general vehicle can be parked only when the distance to the parking compartment is 2 m or more in the case of a right-angle parking, it is difficult to use a system that assists parking of a general vehicle in a narrow passage. .

The present invention has been made to solve the above problems, a vehicle parking assistance method and apparatus for assisting the driver to park easily by varying the parking method according to the type of parking and distance information with the parking compartment or other vehicles. It aims to provide.

In a method for assisting parking of a vehicle, a vehicle parking assisting method for solving the above problem may include: a selective reception step of receiving information selected from one of a right angle parking and a parallel parking mode of the vehicle; A distance acquisition step of obtaining distance information between the parking compartment or another parked vehicle and the vehicle; A method for selecting a parking method using the selected parking type and the obtained distance information; And a parking assistance step of assisting the parking of the vehicle according to the selected parking method.

Preferably, in the information acquisition step, the distance information may be obtained by differently expressing a color located at the parking compartment line according to the distance between the parking compartment line and the vehicle.

Preferably, in the method selecting step, when the selected parking type is the rectangular parking and the obtained distance information exists within a preset range, the selected parking type is the rectangular parking and the obtained distance information is the pre-set. When the selected parking type is the parallel parking and the acquired distance information exists within the preset range, when the selected parking type does not exist within the set range, the selected parking type is the parallel parking and the acquired distance information is set by the preset parking. Different parking methods can be selected by dividing them into cases that do not exist within the range.

A vehicle parking assist device for solving the above problem comprises: a selective reception unit configured to receive information for selecting one of the parking mode of the vehicle as right angle parking or parallel parking; A distance acquisition unit for obtaining distance information between the parking compartment or another parked vehicle and the vehicle; A method selecting unit for selecting a parking method using the selected parking type and the obtained distance information; And a parking assistant configured to assist parking of the vehicle according to the selected parking method.

Preferably, the information acquisition unit may obtain the distance information by differently expressing a color located at the parking compartment line according to the distance between the parking compartment line and the vehicle.

Preferably, when the selected parking type is the right angle parking and the obtained distance information exists within a preset range, the selected parking type is the right angle parking and the obtained distance information is the preset value. If it is not within the range, when the selected parking type is the parallel parking and the obtained distance information exists within the preset range, the selected parking type is the parallel parking and the obtained distance information is the preset range. You can choose different parking methods by dividing them into cases that do not exist within.

The present invention improves the convenience to allow the driver to park easily.

The present invention does not exactly match the parking compartment line with the on-screen display, and the driver can park the vehicle more easily according to the distance from the other vehicle or the distance from the parking compartment line.

Referring to FIG. 1, the vehicle parking assisting apparatus 100 may include a selective reception unit 110, a distance acquisition unit 120, a method selection unit 130, and / or a parking assistance unit 140.

The selective reception unit 110 receives information regarding the type of vehicle parking.

In detail, the selective reception unit 110 may include a right angle parking selection unit 112 and a parallel parking selection unit 114.

The right angle parking selector 112 receives the driver's selection and selects the parking type of the vehicle as the right parking when the driver selects the parking mode as the right parking.

When the driver selects the parking mode as parallel parking, the parallel parking selecting unit 114 receives the driver's selection and selects the parking mode of the vehicle as the parallel parking.

The information regarding the type of vehicle parking received by the selective reception unit 110 may be used for generating information for assisting parking of the vehicle or controlling a vehicle for automatic parking.

The distance acquisition unit 120 acquires distance information between a vehicle to be parked and a parking compartment line forming a parking space or another vehicle forming a parking space.

In detail, the distance acquisition unit 120 may acquire distance information by using various devices provided in the vehicle, such as a rear or side camera, an infrared sensor, and an ultrasonic sensor of the vehicle.

More specifically, when another vehicle is present on the left or right side or both sides of the parking space, and the vehicle exists inside the parking compartment of the vehicle, the distance acquisition unit 120 between the parking compartment of the vehicle and the vehicle to be parked. Measure the distance. On the other hand, if there are other vehicles on the left or right side or both sides of the parking space, and all or part of the vehicle is outside the parking compartment, the distance acquisition unit 120 may be different from other vehicles existing outside and the vehicle to be parked. Measure the distance.

The distance acquisition unit 120 may include a color separation unit 122, a first range unit 124, and a second range unit 126.

In this case, it can be expressed in light blue. Distance range and color may change according to user's setting. However, in the distance range of the color classification unit 122, the same parking assistance method may be applied in the distance range of the same color, and different parking assistance method may be applied in the distance range of the different colors. It would be desirable to vary the distance range according to steering angle performance, system environment, driver disposition, and the like.

The distance obtained by the distance acquisition unit 120 will generally be about 0.5m or more. This is because, in order for the driver to control and park the vehicle, there must be a distance of at least 0.5m from an obstacle such as a vehicle forming the parking space.

Accordingly, the distance acquisition unit 120 may be classified into a first range, a second range, and the like according to the degree of distance.

For example, when the distance information acquired by the distance acquirer 120 exists within a preset distance range, the first ranger 124 may express the distance range as the first range. The preset distance range may be a distance range of 0.5m to 1m, in which parking may be somewhat difficult because the distance is close. The second range part 126 may be represented by a second range of 1m to 2m. According to the size of the parking space, the driver's driving ability, the performance of the vehicle, the size of the vehicle, and the like, the numerical values of 0.5m, 1m, 2m, etc. may be changed.

Such a division range may be three or more, and when the distance obtained by the distance acquisition unit 120 is within 0.5m, a warning that parking is impossible may be provided to the driver as a sound or a screen.

The method selecting unit 130 selects a method of assisting the parking of the vehicle by using the information of the vehicle parking type received by the selection receiving unit 110 and the distance information obtained by the distance obtaining unit 120.

In detail, the method selecting unit 130 selects different parking methods according to whether the vehicle parking type is perpendicular parking or parallel parking and whether the distance acquired by the distance obtaining unit 120 is the first range or the second range. do.
