Novel double-layer vehicle lamp device and control method thereof

Abstract

The invention discloses a novel double-layer vehicle lamp device and a control method thereof. The novel double-layer vehicle lamp device comprises a lamp holder A, a lamp holder B, a dipped headlightA, a dipped headlight B, a servo motor A, a servo motor B, a vehicle lamp angle sensor A, a lamp holder C, a lamp holder D, a dipped headlight C, a dipped headlight D, a servo motor C, a servo motorD, a vehicle lamp angle sensor B, a high beam A, a lamp holder E, a high beam B, a lamp holder F, a vehicle speed sensor, a steering wheel angle sensor, an infrared night vision camera and a master switch which are correspondingly connected with an ECU. The ECU receives detection information obtained by the vehicle lamp angle sensor A, the vehicle lamp angle sensor B, the vehicle speed sensor, thesteering wheel angle sensor and the infrared night vision camera, and controls the four dipped headlights, the two high beams, the four servo motors and the infrared night vision camera according tothe driving condition of a vehicle. The novel double-layer vehicle lamp device and the control method thereof can improve driving safety and avoid traffic accidents to the greatest extent.

Description

Technical field [0001] The invention belongs to the field of automobile safety, and in particular relates to a novel double-layer vehicle lamp device and a control method thereof. Background technique [0002] Statistics and analysis of numerous road traffic accidents show that the incidence of night driving accidents is 1.5 times higher than that during the day, so driving safety at night is highly valued. [0003] At night, when the vehicle is in a turning state, there is a large blind area on the inner side of the curve, which lays hidden dangers for safe driving at night. Therefore, in recent years, an adaptive headlight system has appeared, which can according to the steering direction and speed of the front wheels, The illumination direction of the two low beams is automatically adjusted so that the two low beams illuminate the inside of the curve, thereby reducing the blind area on the inside of the curve and improving the safety of the vehicle at night. However, when the a...

Problems solved by technology

However, when the adaptive headlight system adjusts the irradiation direction of the two low beams, it will reduce the light intensity of other areas such as the front and side of the vehicle, and increase the blind spots in other areas.

[0004] In addition, due to the poor visibility at night, on the one hand, the vision of the driver, pedestrians, cyclists and other traffic participants outside the vehicle is severely limited, which will greatly reduce the driving safety on dangerous road sections; on the other hand, when the vehicle is in a low-speed straight line In the driving state or stopped state, when the driver is looking for the road exit or observing the surrounding road, it is difficult to clearly identify the road condition information, which can easily lead to traffic accidents
