Abstract

A vehicle-reversing display system includes a controller area network, an ultrasonic sensor, a vehicle-reversing image capture device and a display device. The vehicle-reversing image capture device includes a controlling unit and a camera. After a vehicle-reversing parameter of the controller area network is acquired, the controlling unit recognizes a distance from an obstacle through the ultrasonic sensor. If the distance is a first distance, the camera is automatically switched to a wide field-of-view mode under control of the controlling unit. If the distance is a second distance, the camera is automatically switched to a normal field-of-view mode under control of the controlling unit. If the distance is a third distance, the camera is automatically switched to a top field-of-view mode under control of the controlling unit. An auxiliary image is displayed on the display device.

Claims

1. A vehicle-reversing display system capable of automatically switching multiple field-of-view modes, comprising:

a controller area network providing a vehicle-reversing parameter;

an ultrasonic sensor connected with the controller area network;

a vehicle-reversing image capture device comprising a controlling unit and a camera, wherein the controlling unit is connected with the controller area network, and the camera is connected with the controlling unit; and

a display device connected with the camera,

wherein after the vehicle-reversing parameter of the controller area network is acquired by the controlling unit, the controlling unit recognizes a distance from an obstacle through the ultrasonic sensor, wherein if the distance is a first distance, the camera is automatically switched to a wide field-of-view mode under control of the controlling unit, wherein if the distance is a second distance, the camera is automatically switched to a normal field-of-view mode under control of the controlling unit, wherein if the distance is a third distance, the camera is automatically switched to a top field-of-view mode under control of the controlling unit, wherein an auxiliary image corresponding to the wide field-of-view mode, the normal field-of-view mode, or the top field-of-view mode is captured by the camera and displayed on the display device.

2. The vehicle-reversing display system according to claim 1, wherein the ultrasonic sensor is an ultrasonic reverse parking radar.

3. The vehicle-reversing display system according to claim 1, wherein the first distance is longer than 1 meter, the second distance is in a range between 0.5 and 1 meter, and the third distance is shorter than 0.5 meter.

4. The vehicle-reversing display system according to claim 1, wherein a horizontal viewing angle of the camera in the wide field-of-view mode is in a range between 170 and 190 degrees, a horizontal viewing angle of the camera in the normal field-of-view mode is in a range between 110 and 150 degrees, and a vertical viewing angle of the camera in the top field-of-view mode is in a range between 60 and 90 degrees.

5. The vehicle-reversing display system according to claim 1, wherein plural virtual parking lines are contained in the auxiliary image corresponding to the normal field-of-view mode.

6. The vehicle-reversing display system according to claim 1, wherein a vertical virtual parking mark is contained in the auxiliary image corresponding to the top field-of-view mode.

7. A vehicle-reversing image capture device of a vehicle-reversing display system, the vehicle-reversing display system comprising a controller area network, an ultrasonic sensor and a display device, the vehicle-reversing image capture device comprising:
