Embodiment 1

[0031] refer to Figure 1-5 , figure 1 A system block diagram of a safety information prompt system that restricts dangerous driving provided by the present invention; figure 2 A block diagram of an image capture device outside the vehicle of a safety information prompt system that restricts dangerous driving provided by the present invention; image 3 A block diagram of an in-vehicle image capture device for a safety information prompt system that restricts dangerous driving provided by the present invention; Figure 4 A flow chart of in-vehicle image judgment for a safety information prompt system that restricts dangerous driving provided by the present invention; Figure 5 It is a flow chart of judging images outside the vehicle of a safety information prompt system that restricts dangerous driving provided by the present invention.

[0032]Specifically, a safety information prompt system for restricting dangerous driving includes a control processor 1 and an image capt...

Embodiment 2

[0038] refer to Figure 6-7 , Figure 6 A system block diagram of the second safety information prompt system that restricts dangerous driving provided by the present invention; Figure 7 It is a flow chart of lifting restrictions of the second safety information prompt system that restricts dangerous driving provided by the present invention.

[0039] This embodiment is basically the same as the first embodiment above, the difference is that, preferably, it also includes a voice playback device 4 and a voice acquisition device 5 , both of which are connected to the control processor 1 . The control processor 1 outputs voice information to the voice playback device 4, and the voice playback device 4 plays the voice information. The voice acquisition device 5 acquires the sound in the car, and extracts the human voice, converts the human voice into an electrical signal and outputs it to the control processor 1, and the control processor 1 acquires the electrical signal of the...

Embodiment 3

[0044] refer to Figure 8-9 , Figure 8 It is a flow chart of judging the first eye image of the third safety information prompt system that restricts dangerous driving provided by the present invention; Figure 9 It is a flowchart of the second eye image judgment of the third safety information prompt system that restricts dangerous driving provided by the present invention.

[0045] This embodiment is basically the same as the first embodiment above, except that, preferably, the in-vehicle capturing device captures the user's eye image and outputs it to the control processor 1 . The in-vehicle capture device is a high-definition camera.

[0046] Preferably, when the control processor 1 determines that the user's eye blink frequency is higher than the preset blink threshold, the control processor 1 determines that the user is not suitable for driving; when the control processor 1 determines that the user's eyes secrete tears, The control processor 1 determines that the use...

Abstract

The invention relates to a safety information prompt system for limiting dangerous driving. The safety information prompt system comprises a control processor and an image capture device, wherein theimage capture device comprises a vehicle interior capture device and a vehicle exterior capture device, and the image capture device is connected with the control processor; the vehicle interior capture device is used for capturing a vehicle interior image, and the control processor acquires the vehicle interior image and judges whether abnormal operation of a user exists or not; the vehicle exterior capture device is used for capturing a vehicle exterior image, and the control processor acquires the vehicle exterior image and judges whether abnormal driving exists or not; the control processor is also connected with a vehicle control module, and the vehicle control module comprises a start control module and a vehicle speed control module; when the control processor judges that the abnormal operation of the user exists, the control processor outputs a start locking signal to the start control module; and when the control processor judges that the abnormal driving of the user exists, the control processor outputs a vehicle speed limiting signal to the vehicle speed control module.

Description

technical field [0001] The invention relates to the technical field of automotive electronic equipment, in particular to a safety information prompt system for limiting dangerous driving. Background technique [0002] With the continuous and rapid development of my country's transportation industry and economy, automobiles have increasingly become the most important means of transportation for people to travel, but the negative effects of traffic safety that follow have become more and more prominent social problems, and have become global issues. [0003] As far as the current automobile industry is concerned, in terms of automobile manufacturing, active safety technologies such as Eye Car technology, Cam Car technology, and tire pressure monitoring systems, and passive safety technologies such as airbags, adaptive restraint technology systems, and automotive energy-absorbing steering columns The development and use have been quite mature, which has greatly improved the saf...
