Abstract

Provided are an independent wireless rear/side video transceiver for a vehicle and a method thereof. The independent wireless video transmitter for a vehicle according to an exemplary embodiment of the present invention, which includes: an accelerometer that senses start and reverse movement of a vehicle and outputs the sensed result to a controller unit; a camera module that outputs a video signal acquired by photographing the rear of the vehicle to the controller unit; a solar cell that converts light into electricity; a battery that is charged with the electricity generated from the solar cell; a power management unit that controls the solar cell and the battery; a wireless transmission unit that wirelessly transmits a video signal outputted from the controller unit; and the controller unit that determines and controls input/output signals of the accelerometer, the camera module, the power management unit, and the wireless transmission unit.

Claims

1. An independent wireless video transmitter for a vehicle, comprising:

an accelerometer that senses start and reverse movement of a vehicle and outputs the sensed result to a controller unit;

a camera module that outputs a video signal acquired by photographing the rear of the vehicle to the controller unit;

a solar cell that converts light into electricity;

a battery that is charged with electricity generated from the solar cell;

a power management unit that controls the solar cell and the battery;

a wireless transmission unit that wirelessly transmits a video signal outputted from the controller unit; and

the controller unit that determines and controls input/output signals of the accelerometer, the camera module, the power management unit, and the wireless transmission unit,

wherein the independent wireless video transmitter is not physically connected to the vehicle, for power and signals.

2. The independent wireless video transmitter for a vehicle according to claim 1, further comprising a photosensor that senses illumination around the photographed area and outputs the illumination to the controller unit.

3. The independent wireless video transmitter for a vehicle according to claim 1, wherein the controller unit of the wireless video transmitter gives an identification number to a video signal outputted from the camera module.

4. An independent wireless video transceiver for a vehicle, comprising:

the independent wireless video transmitter for a vehicle according to claim 1; and

a wireless video receiver including;

a wireless receiving unit that receives a video signal transmitted from the wireless transmission unit of the independent wireless video transmitter for a vehicle;

a display that outputs a signal received by the wireless receiving unit; and

a controller for the wireless video receiver which controls the wireless receiving unit and a display to display the received video signals.

9. An independent wireless video transceiver for a vehicle, comprising:

the independent wireless video transmitter for a vehicle according to claim 2; and

a wireless video receiver including;

a wireless receiving unit that receives a video signal transmitted from the wireless transmission unit of the independent wireless video transmitter for a vehicle;

a display that outputs a signal received by the wireless receiving unit; and

a controller for the wireless video receiver which controls the wireless receiving unit and a display to display the received video signals.

10. An independent wireless video transceiver for a vehicle, comprising:

the independent wireless video transmitter for a vehicle according to claim 3; and

a wireless video receiver including;

a wireless receiving unit that receives a video signal transmitted from the wireless transmission unit of the independent wireless video transmitter for a vehicle;

a display that outputs a signal received by the wireless receiving unit; and

a controller for the wireless video receiver which controls the wireless receiving unit and a display to display the received video signals.

5. An independent method of wirelessly transmitting video for a vehicle, comprising:

sensing reverse movement of a vehicle and an external shock by using an accelerometer, and outputting a sensing signal to a controller unit;

supplying power to a camera module and a wireless transmission unit by converting a wireless video transmitter from a power saving mode into an operation mode, and setting a transmission channel of the wireless transmission unit, when the sensing signal is inputted;

giving an identification number to a video signal inputted from the camera module;

transmitting the video signal with the identification number through the wireless transmission unit;

determining whether the vehicle is reversing, on the basis of the signal inputted from the accelerometer; and

continuously transmitting video signals, when the vehicle is reversing, and stopping the transmission of video signals and operating in a power saving mode, when the vehicle is moving forward.

6. The independent method of wirelessly transmitting video for a vehicle according to claim 5, further comprising determining an external shock and transmitting video signals with shock-sensing signals continuously allocated with identification number signals regardless of the traveling direction of the vehicle, when a signal corresponding to a strong shock is inputted from the accelerometer.

7. The independent method of wirelessly transmitting video for a vehicle according to claim 5, further comprising setting the camera module in a day or night mode by analyzing an illumination signal of a photosensor.

8. The independent method of wirelessly transmitting video for a vehicle according to claim 5, further comprising determining a signal outputted from the accelerometer and transmitting a video signal corresponding to a turn direction of the vehicle equipped with a plurality of cameras.
