Further, the intelligent navigation application module is also used to take screenshots of the navigation of the current road conditions when the fatigue driving analysis module determines that the driver is currently in a fatigue driving state and send them to the fatigue driving analysis module for later analysis of the cause of fatigue driving.

Further, the fatigue driving analysis module combines the current road information and the steering wheel operation data to judge the fatigue driving analysis includes: the fatigue driving analysis module compares the steering wheel operation information of the driver on the current road with the driver's operating habit data information, When deviations occur within a certain period of time, it is determined that this is a fatigue driving state.

Further, the driver's operating habit data information comes from the collection of the driver's normal operation of the steering wheel in advance. The specific method is: select a road with different road condition information through the intelligent navigation application module, and confirm that the driver is not driving fatigued. The steering wheel data collector collects the steering wheel data in real time and transmits it to the vehicle navigation terminal for storage, and the stored operation data is used as the driver's operating habit data information.

Further, the corresponding operation of the fatigue driving analysis module according to the judgment result includes: if it is judged that the driver is currently in a fatigue driving state, giving an alarm reminder.

The invention has the beneficial effects of: analyzing and judging whether the driver is fatigued, reminding the driver, and effectively reducing traffic accidents caused by fatigued driving.

detailed description

The present invention aims to propose a navigation safety system for preventing fatigue driving, which analyzes and judges whether the driver is fatigue driving, and reminds the driver. Its core idea is: collect the steering wheel operation habits of the driver during normal driving, collect the steering wheel operation data in real time during the driver's driving process, and combine the road condition information obtained by the intelligent navigation system to compare the steering wheel operation data and the driver's operation. Habits are compared to determine whether it is fatigue driving, which serves as a reminder to the driver.

Below in conjunction with accompanying drawing, scheme of the present invention is further described:

As shown in Figure 1, the navigation safety system for preventing fatigue driving in the present invention includes a vehicle navigation terminal and a steering wheel data collector;

Among them, the steering wheel data collector is used to collect steering wheel operation data and transmit it to the vehicle navigation terminal; the relevant content of the steering wheel operation data includes: left turn data, right turn data, straight travel data, car gear data, front and rear light data. In specific implementation, the data collector directly uploads the above-mentioned relevant data content to the CPU of the vehicle navigation terminal through the CAN bus, and waits for data comparison and analysis.

The vehicle-mounted navigation terminal is loaded with an intelligent navigation application module and a fatigue driving analysis module; the intelligent navigation application module is used to provide real-time navigation of road information, and sends the road information to the fatigue driving analysis module; the fatigue driving analysis module combines the current The road information and steering wheel operation data are used to judge the fatigue driving analysis and perform corresponding operations according to the judgment results.

In the specific implementation, it is first necessary to collect the user’s operating habit information on the steering wheel during normal driving, as the basic data for later judgment of fatigue driving, the collection method is as follows: the driver selects several segments through the intelligent navigation application module On roads with rich road condition information, the driver guides the driving. After confirming that the driver is not tired, the driver drives according to the information prompts. The steering wheel data collector collects and stores the data of the driver's operation of the steering wheel as a driver Operation habit information; road condition selection mainly includes: crossroads, T-junctions, one-way roads, double-star roads, multi-intersections, expressway roads, bridge roads, overpass roads, underpass roads and tunnels and other roads. Since the road condition information of different roads is different, in order to improve the accuracy of fatigue driving analysis in the later stage, the data of operating the steering wheel can be collected and stored on these selected road conditions many times.

For those skilled in the art, it can be understood that the more data collected on the driver's operating habits in the early stage, the more accurate the fatigue driving analysis and comparison in the later stage;

After storing a certain amount of data on the driver's operating habits, the fatigue driving analysis function can be enabled, which specifically includes:

During the driving process of the driver, the steering wheel data collector collects the data of the driver's operation of the steering wheel in real time and transmits the data to the vehicle navigation terminal. Compared with the normal operating habits of the driver on the corresponding road conditions, when a deviation is found for a certain period of time, it can be determined that the driver is currently in a fatigue driving state. At this time, an alarm can be issued to the driver, and the current road condition can also be monitored Take a screenshot of the navigation to facilitate the driver to analyze the cause of fatigue driving.
