Vehicle-mounted color blindness auxiliary driving device

Abstract

The invention discloses a vehicle-mounted color blindness auxiliary driving device which comprises a shell, an electronic circuit board, a GPS navigator arranged in a vehicle driven by a color-blind driver and a speed sensor for detecting the running speed of the vehicle driven by the color-blind driver in real time. An MCU processor, a wireless communication module, an A/D converter and a timing circuit are arranged on the electronic circuit board, the wireless communication module is connected with the MCU processor and used for receiving on-off control state information of a traffic light controller on traffic lights under the current state, and the A/D converter and the timing circuit are connected with the MCU processor. A liquid crystal display screen and a voice prompt unit are arranged on the shell. The device is reasonable in circuit design, wiring is easy and convenient, mounting and layout are convenient, investment cost is low, the intelligent degree is high, the use effect is good, and when the vehicle runs to a road junction with the traffic lights, the color-blind driver can be automatically informed of the on-off control state of the front traffic lights under the current state in a voice prompt mode.

Description

technical field [0001] The invention relates to a driving assistance device, in particular to a vehicle-mounted color-blind driving assistance device. Background technique [0002] Color blindness refers to congenital color vision impairment, unable to distinguish various colors or a certain color in the natural spectrum. According to statistics, male red-green color blind patients account for about 7% of the total population in my country, and female red-green blind patients account for about 0.8% of the total population. However, my country's traffic law clearly stipulates that patients with red-green color blindness are not allowed to drive motor vehicles. The main reason is that patients with red-green color blindness cannot or are not easy to distinguish the commonly used red and green traffic lights. However, since driving a car is already a need of daily life, it is necessary to design a color-blind driving assistance system. Nowadays, the color-blind driving system...

AI Technical Summary

Problems solved by technology

Nowadays, the color-blind driving systems that appear are generally based on image recognition-based driving assistance recognition systems, and the investment cost is relatively high, so they cannot be popularized and applied.

To sum up, there is a lack of a color-blind driving assistance system with reasonable circuit design, simple wiring, convenient installation and layout, low investment cost, high degree of intelligence, and good use effect, which can easily and quickly remind color-blind drivers of the traffic ahead Light status, when the vehicle reaches the intersection where the traffic lights are installed, it can automatically inform the color-blind driver of the switch control status of the traffic lights ahead in the current state through voice prompts
