Abstract

An automobile includes an anti-dazzling system and a luminous body. The anti-dazzling system includes a sensing module, a calculating unit, a controlling module and a display module. The sensing module includes a signal receiver and a recorder. The signal receiver defines a through hole and a signal receiving chip is received therein. The signal receiving chip can receive infrared light through the hole. The recorder can obtain an emitting time and a receiving time of the infrared light, and send the emitting time and the receiving time to the calculating unit. The calculating unit calculates a size and a location of the display module to be shielded, and sends the size and the location of area to be shielded to the controlling module to control the correspondingly area of the display module being opaque or translucent. The present disclosure also provides an anti-dazzling method.

Claims

1. An automobile comprising:

a high beam including a luminance body; and

an anti-dazzling system configured to prevent dazzling a driver of an oncoming automobile, the anti-dazzling system comprising;

a sensing module having a signal receiver mounted on the automobile and a recorder;

a processing module including a calculating unit;

a controlling module; and

a display module positioned in front of the luminance body;

wherein the sensing module, the processing module, the controlling module, and the display module are electrically connected in sequence;

wherein the signal receiver includes a signal receiving chip therein and defines a through hole;

the signal receiving chip is adapted for receiving an infrared light carrying signal codes including a signal code of a windshield size of a windshield of the oncoming automobile via the through hole;

the recorder is configured to obtain an emitting time and a receiving time of the infrared light;

wherein the signal receiver and the recorder are configured to send the infrared signal, the emitting time and the receiving time of the infrared light to the calculating unit;

wherein the calculating unit is adapted for calculating a distance between the signal receiver and a point at which transmitting the infrared light based on the emitting time and the receiving time, and calculating an incident angle of the infrared light based on a point on the signal receiving chip received the infrared light and the location of the through hole, such that a size and a location of an area of the display module to be shielded can be calculated by the calculating unit based on the distance between the luminance body and the display module in combination with the windshield size of the oncoming automobile, and fed back to the controlling module; and

wherein a portion of the display module is configured to prevent the light illuminated from the luminance body from glaring the driver of oncoming automobile.

2. The automobile as claimed in claim 1, wherein the sensing module further comprises a signal generator mounted on the automobile, and the signal generator is configured to transmit the infrared light carrying the signal codes including the windshield size.

3. The automobile as claimed in claim 2, wherein the signal codes carried by the infrared light further includes a signal code of a location relationship between the windshield and the signal generator.

4. The automobile as claimed in claim 3, wherein the signal codes carried by the infrared light further includes a signal code of requesting to open the anti-dazzling system.

5. The automobile as claimed in claim 4, wherein the processing module further comprises a filtering unit electrically connected to the signal generator and the calculating unit, and the filtering unit is capable of filtering out the signal code of requesting to open the anti-dazzling system, the signal code of the location relationship of the windshield and the signal generator, and the signal code of the windshield size, and sending the signal to the calculating unit.

6. The automobile as claimed in claim 1, wherein the display module is a liquid crystal display, and the portion configured to prevent the light illuminated from the luminance body from glaring the driver of oncoming automobile is opaque or translucent.

7. An anti-dazzling method for automobiles comprising:

transmitting an infrared light carrying signal codes comprising a windshield size by a signal generator, and recording an emitting time of the infrared light by a recorder;

receiving the infrared light by a signal receiving chip received in a signal receiver via a through hole defined on the signal receiver, and recording a receiving time of the infrared light by the recorder;

sending to the signal codes received by the signal receiver to a calculating unit of a processing module by the signal receiver, and sending the emitting time and the receiving time to the calculating unit by the recorder;

calculating a distance between the signal generator and the signal receiver based on the emitting time, the receiving time, and calculating an incident angle of the infrared light toward the signal receiving chip based on a location of the receiving point of the signal receiving chip and a location of the through hole by the calculating unit;

calculating a location and a size of an area to be shielded on a display module based on the distance between the luminance body and the display module in combination with the windshield size, and sending a signal of the location and the size of the area to be shielded to a controlling module; and

controlling the area to be shielded on the display module to be opaque or translucent.

8. The anti-dazzling method for automobiles as claimed in claim 7, wherein the anti-dazzling method further comprises a step of encoding the signal codes by the calculating unit.

9. The anti-dazzling method for automobiles as claimed in claim 7, wherein the signal codes carried by the infrared light transmitted from the signal generator comprises a signal code of the windshield size of the automobile.
