Problems solved by technology
[0004] Open a triangular window on the A-pillar, or make the A-pillar thinner, this solution will reduce the strength of the A-pillar and affect the safety of the car
[0005] The driver can only look down at the blind spot on the display screen, which will cause inconvenience to the driver and increase the risk of driving
[0006] There is no obvious early warning and alarm function, and the driver cannot react immediately if he encounters a dangerous situation in the blind spot while driving

Embodiment Construction
[0031] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention. In addition, "first", "second", etc. are only used for distinguishing descriptions, and should not be construed as indicating or implying relative importance.
[0032] In the existing technology, the driver needs to lower his head to observe the A-pillar blind area image presented on the display screen, which is a little inconvenient in operation, and when encountering an emergency, there is no obvious warning signal, and the driver is likely to fail to respond in time, thus In the event of a traffic accident, there are certain potential safety hazards.
[0033] According to the embodiment of the present invention, ...

The invention relates to an audio and video device capable of eliminating automobile A-pillar blind area and performing surrounding environment early warning. The audio and video device comprises fisheye cameras, a calculation and comprehensive imaging module, a soft screen imaging module, a liquid crystal soft screen display, sensors, an early warning system and alarms. One group of fisheye cameras and sensors are mounted on the outer side of an A pillar of the automobile, and one group of fisheye cameras are mounted on rearview mirrors of the automobile to monitor the real-time condition ofa blind area on the outer side of the automobile; the calculation and comprehensive imaging module processes pictures shot by the cameras and transmits the pictures to the soft screen imaging module;the liquid crystal soft screen display images the image information of the blind area on the outer side of the automobile; and the early warning system and the alarms give an alarm for sudden dangerous situations. According to the audio and video device capable of eliminating automobile A-pillar blind area and performing surrounding environment early warning, on the basis of guaranteeing the structural strength of an original A pillar, the visual field is expanded; and the distress warning function is added, and the driving risk is reduced.
Description
technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to an audio-visual device for eliminating the blind area of the A-pillar of the automobile and early warning of the surrounding environment. Background technique [0002] The A-pillar blind area refers to the blind area of vision when the car is driving. Whenever the car is turning or entering a curve, the driver's field of vision will be partially blocked by the A-pillar, resulting in a blind spot in the field of vision. The blind area of the A-pillar of the automobile has always been a problem that has not been completely solved, and it is the main cause of related traffic accidents. [0003] In the existing related technologies, in order to eliminate the influence of the A-pillar blind zone, the following three schemes are mainly adopted: [0004] Opening a triangular window on the A-pillar or thinning the A-pillar will reduce the strength of the...
