Technical Field

The invention relates to the technical field of vehicle safety alarm, in particular to a vehicle rear blind area safety alarm system.

Background

Along with the development of traffic, the overall situation of road traffic safety and the traffic safety risk in China are always in a high-risk running state, which shows that traffic accidents occur frequently, and particularly shows that visual blind areas exist below left and right side doors and behind a vehicle body of a vehicle when the vehicle runs, once obstacles, other vehicles and pedestrians exist in the visual blind areas of the vehicle, a driver cannot detect the visual blind areas in the vehicle, and the traffic accidents are caused.

To the field of vision blind area of vehicle, adopt the front end both sides installation reflector at the vehicle at present mostly to cooperation radar sensing and camera make the driver can know the barrier of vehicle field of vision blind area comprehensively in the car, but, specific still can have certain drawback when using, and vehicle traffic accident frequently takes place, and concrete drawback shows to be:

1. the camera is used for transmitting the blind area picture to the display screen, and the radar sensor is used for sending out early warning operation, or a driver is required to observe the condition of an obstacle on the display screen at any time, so that early warning is delayed, and the early warning function is insufficient;

2. at present, the blind area detection of vehicles only shows that the blind area detection of vehicles plays a role in prompting drivers and pedestrians, and sometimes, the drivers cannot timely make corresponding measures due to personal reasons or other reasons, and traffic accidents are easily caused;

3. the function is single, can't realize the early warning modularization to corresponding early warning measure and safeguard measure can't be made, all need rely on the subjective consciousness operation of driver, and then lead to some drivers still be "my element", can't guarantee driver's security.

In view of the above situation, the invention provides a vehicle rear blind area safety alarm system, which can realize early warning modularization processing and make corresponding protection measures, realize early warning and protection simultaneously, and maximize the safety of a driver.
