The detection method for detecting the vehicle front information according to claim 2, characterized in that the operating state of the vehicle lamp includes: and when the resistance value of the photosensitive element is reduced, the angle of the reflecting cup is controlled to be downwards deviated and/or the light source light power of the car lamp is reduced.
6. The detection method for detecting the vehicle front information according to claim 2, characterized in that the resistance value change information further includes: and when the average value is lower than a preset resistance value, the vehicle lamp is controlled to automatically close the high beam.
7. A detection system for detecting vehicle front information, characterized by comprising:
a vehicle lamp provided with a photosensor;
the detection module is connected with the photosensitive element and is used for acquiring resistance value change information of the photosensitive element of the vehicle lamp;
the control module is connected with the car lamp and the detection module and is used for controlling the vehicle to send prompt information to a driver and/or controlling the working state of the car lamp according to the resistance value change information so as to prompt the driver to pay attention to an obstacle in front of the vehicle and/or reduce the influence on an opposite vehicle;
and the reminding module is connected with the control module and is used for sending reminding information to a driver.
8. The detection system for detecting vehicle front information according to claim 7, characterized in that the resistance value change information includes: the detection module is used for obtaining the current change information flowing through the photosensitive element according to the resistance change information of the photosensitive element;
when the resistance value of the photosensitive element is increased, the control module controls the reminding module to send prompt information to a driver so as to prompt the driver to pay attention to an obstacle in front of the vehicle;
the high beam is turned on by the car lamp, and when the average value is lower than a preset resistance value, the control module controls the car lamp to automatically turn off the high beam.
9. The detection system for detecting vehicle front information according to claim 8, characterized in that the operating state of the lamp includes: when the resistance value of the photosensitive element is reduced, the control module is suitable for controlling the angle of the reflection cup to be downwards deviated and/or reducing the light source light power of the car lamp.
10. A vehicle characterized by comprising the detection method for detecting vehicle front information according to any one of claims 1 to 6.
