Abstract

The present disclosure relates to an around view monitor (AVM) system that provides image information on the ambient conditions of a vehicle to a driver. In displaying a top-view image in which the front, rear, left, and right conditions of a vehicle are seen downward from a portion over the vehicle, an AVM system and method checks a driving state or driving direction of the vehicle on the basis of information received from sensors and elements included in the vehicle, and outputs the top-view image which is suitably edited depending on the driving conditions, thereby providing information necessary for driving to a driver.

Claims

1. An around view monitor (AVM) system, comprising:

an image data receiver receiving a data signal on an image captured by at least one or more camera attached to a vehicle;

a vehicle information receiver receiving gear information from a transmission of the vehicle, and receiving vehicle speed information from a vehicle speed sensor of the vehicle; and

a controller generating a top-view image with the image data, determining a driving state of the vehicle on the basis of the gear information and vehicle speed information, and editing and outputting the top-view image such that different portions in the top-view image are displayed on a screen depending on the driving state.

2. The AVM system of claim 1, wherein,

when the gear information is a driving state and the vehicle speed is higher than or equal to a first reference speed, the controller determines that the vehicle is driving forward, or

when the gear information is a reverse state and the vehicle speed is higher than or equal to a second reference speed, the controller determines that the vehicle is backing.

3. The AVM system of claim 2, wherein when the gear information is a neutral state and the vehicle speed is lower than or equal to a third reference speed, the controller determines the vehicle as being in the stop state.

4. The AVM system of claim 1, wherein,

when the gear information is a driving state, the controller determines that the vehicle is driving forward, or

when the gear information is a reverse state, the controller determines that the vehicle is backing.

5. The AVM system of claim 1, wherein,

when the driving state is a forward state, the controller edits and outputs the top-view image such that a front image of the vehicle is displayed broader than a rear image of the vehicle in the top view, or

when the driving state is a reverse state, the controller edits and outputs the top-view image such that the rear image is displayed broader than the front image in the top view.

6. The AVM system of claim 1, wherein the controller edits and outputs the top-view image such that front and rear images of the vehicle in the top view are displayed at different ratios, according to a level of the vehicle speed.

7. The AVM system of claim 2, wherein the controller edits and outputs the top-view image such that front and rear images of the vehicle in the top view are displayed at different ratios, on the basis of a difference between the vehicle speed and the first reference speed or a difference between the vehicle speed and the second reference speed.

9. The AVM system of claim 1, wherein,

the vehicle information receiver receives the steering angle information of the vehicle from the steering wheel angle sensor of the vehicle, and

the controller determines a driving state of the vehicle and checks a driving direction of the vehicle, on the basis of the gear information, the vehicle speed information, and the steering angle information.

8. An around view monitor (AVM) system, comprising:

an image data receiver receiving a data signal on an image captured by at least one or more camera attached to a vehicle;

a vehicle information receiver receiving gear information from a transmission of the vehicle, and receiving steering angle information from a steering wheel angle sensor of the vehicle; and

a controller generating a top-view image with the image data, determining a driving direction of the vehicle on the basis of the gear information and vehicle speed information, and editing and outputting the top-view image such that different portions in the top-view image are displayed on a screen depending on the driving direction.

10. The AVM system of claim 8, wherein the controller edits and outputs the top-view image such that an image in a direction matched with the driving direction has a high ratio in the top view.

11. An around view monitor (AVM) method, comprising:

receiving image data obtained by a camera to generate a top-view image, the camera being attached to a vehicle;

receiving gear information from a transmission of the vehicle, and receiving vehicle speed information from a vehicle speed sensor of the vehicle;

determining a driving state of the vehicle on the basis of the gear information and vehicle speed information; and

editing and outputting the top-view image such that different portions in the top-view image are displayed on a screen depending on the driving state.

12. The AVM method of claim 11, wherein the determining the driving state comprises:

determines that the vehicle is driving forward, when the gear information is a driving state and the vehicle speed is higher than or equal to a first reference speed, the controller;

determining that the vehicle is backing, when the gear information is a reverse state and the vehicle speed is higher than or equal to a second reference speed, the controller; and

determining the vehicle as being in a stop state, when the gear information is not the driving state or the reverse state.

13. The AVM method of claim 11, wherein the editing and outputting the top-view image comprises editing and outputting the top-view image such that an image in a direction matched with the driving direction has a ratio higher than an image in an opposite direction, in a screen.

14. The AVM method of claim 11, wherein the editing and outputting the top-view image comprises editing and outputting the top-view image such that a ratio of a front or rear image of the vehicle increases or decreases in proportion to the vehicle speed, in a screen.
