Embodiment approach

[0037] like figure 1 As shown, the infrared probe 1 involved in the present invention is respectively arranged on the front bumper 6 and is positioned at the left and right ends of the vehicle body side and the inside of the left and right rear tail lights 8 of the vehicle; Two alarm horns 2 are respectively arranged on both sides below; the structure of the light strobe alarm device is that two bright LED alarm lights 3 are respectively arranged on the left and right exterior mirrors 9 of the vehicle body.

specific Embodiment approach

[0041] like figure 1As shown, the detection area of ​​the infrared probe 1 disposed on the front bumper 6 at the left and right ends of the vehicle body is the A-pillar detection area 4, which is the detection blind area blocked by the A-pillar when the driver is driving normally. ; The detection area of ​​the infrared probe 1 that is arranged on the inside of the left and right rear taillights 8 of the vehicle is the side rear detection area 5, which cannot be seen from the left and right outside of the vehicle body when the driver is visually driving in this area. The mirror 9 observes the side rear detection blind area of ​​the reflected image.

[0042] When the alarm requirements are met, the vehicle operation control unit activates the bright LED alarm lights mounted on the two exterior rearview mirrors 9 to flash, and at the same time, the two alarm horns 2 on both sides below the instrument panel 7 give out alarm sounds. Remind the driver that there are obstacles in th...

Embodiment 3

[0044] In this embodiment, considering the differences in the physical conditions of different drivers, the following schemes are proposed for the setting of each infrared probe 1:

[0045] The installation structure of each infrared probe 1 described above is provided with a fine-tuning structure for detection angle and detection position.

[0046] The above scheme can adapt to different heights and the habit of adjusting the driver's seat, and properly adjust the detection angle and position of each infrared probe 1 . The adjustment structure of the detection angle can adopt the structure of a universal joint, which is locked after adjustment; the adjustment structure of the detection position can adopt different schemes, for example, the scheme of adopting a long slotted hole.

[0047] The second problem to be solved by the present invention is to provide the detection and alarm method adopted by the above-mentioned vehicle blind spot detection and alarm device, the purpose...

Abstract

The invention pertains to the technical field of vehicle construction, discloses a blind zone detecting and alarm device for vehicles, wherein, an infrared probe (1) is multiple passive infrared receivers; the alarm device is divided into an audible alarm device and a light stroboflash alarm device. The infrared probe (1), the audible alarm device and the light stroboflash alarm device are all connected with the operating control unit of the vehicle by signal lines. Detection zones cover an A pole blind zone and blind zones at the side and the back of the vehicle by adopting the technical proposal, and the disadvantages of poor active infrared anti-jamming performance and complex structure are overcome; the passive infrared detector does not emit any radiation and has the advantages of quite low device power consumption, high sensitivity, comparatively good invisibility, low cost, convenient arrangement and being artistic and practical; the mode combined with the audible alarm and the light stroboflash alarm gives drivers sufficient alarm information to guarantee driving safety.

Description

technical field [0001] The invention belongs to the technical field of automobile construction, and relates to a signal detection and alarm system for vehicle operation, more specifically, the invention relates to a vehicle blind spot detection and alarm device. In addition, the present invention also relates to a detection and alarm method adopted by the detection and alarm device. Background technique [0002] For the acquisition of scene information for overtaking and changing lanes, at present most rely on the driver’s visual inspection of the front and observation of the rearview mirror. Due to the blocking of the A-pillar and the existence of blind spots in the rearview mirror, this subjective judgment brings inconvenience to driving. safety factors. [0003] At present, the research on the detection of blind spots in the A-pillar field of view and side and rear blind spots, and the lane change alarm is in its infancy. Among the known prior art, signal detection and ...
