Further, described fatigue driving analysis module carries out corresponding operating according to judged result and includes: if judging, driver is currently as fatigue driving state, carries out warning reminding。
The invention has the beneficial effects as follows: to driver, whether fatigue driving is analyzed judging, reminds driver, effectively reduces the vehicle accident because fatigue driving causes。
Accompanying drawing explanation
Fig. 1 is the mutual schematic diagram of the navigation safety system in the present invention。
Detailed description of the invention
It is contemplated that propose a kind of navigation safety system for preventing fatigue driving, to driver, whether fatigue driving is analyzed judging, reminds driver。Its core concept is: gather steering wheel operation custom during driver's normal driving, the operation data of steering wheel are acquired by driver's driving procedure in real time, the traffic information that combined with intelligent navigation system obtains determines whether fatigue driving by the operation data of steering wheel and the operating habit of driver are carried out contrast, and driver is played reminding effect。
Below in conjunction with accompanying drawing, the solution of the present invention is described in further detail:
As it is shown in figure 1, the navigation safety system of the preventing fatigue driving in the present invention includes vehicle mounted guidance terminal and steering wheel data acquisition unit；
Wherein, steering wheel data acquisition unit is used for gathering steering wheel operation data and sending vehicle mounted guidance terminal to；Related content for steering wheel operation data includes: left-hand rotation data, right-hand rotation data, craspedodrome data, automobile gears data, front and back lamp data。On being embodied as, data acquisition unit passes through CAN, directly, in above-mentioned related data content uploading to the CPU of vehicle mounted guidance terminal, waiting for data and compare and analyze。
Vehicle mounted guidance terminal is loaded with intelligent navigation application module and fatigue driving analysis module；Described intelligent navigation application module is for providing the real-time navigation of road information, and road information sends to fatigue driving analysis module；Described fatigue driving analysis module carries out the judgement of fatigue driving analysis in conjunction with present road information and steering wheel operation data and carries out corresponding operating according to judged result。
In the specific implementation, firstly the need of operating habit information to steering wheel when gathering user's normal driving, to judge whether the basic data of fatigue driving as the later stage, gather mode as follows: driver by the intelligent navigation application module in vehicle mounted guidance terminal select some sections of traffic informations enrich road, carry out driver and guide driving, when confirming that driver is not tired, driver drives according to information alert, by steering wheel data acquisition unit, the data of operator steering wheel are acquired storage, using the operating habit information as driver；Road conditions select mainly to comprise: crossroad, T-shaped road junction, one way traffic, double star road, Multiple Intersections, expressway road, bridge way, viaduct road, the road such as underway and tunnel。Owing to the traffic information of different roads is all different, in order to improve the accuracy that fatigue driving analyzed by the later stage, it is possible to be repeatedly acquired the data of direction of operating dish storing in the road conditions of these selections。
To those skilled in the art, it is to be understood that early stage is for data acquisition more many of driver's operating habit, and it is more accurate that contrast is analyzed in the fatigue driving in later stage；
Just can enabling fatigue driving analytic function after the data storing a certain amount of driver's operating habit, it specifically includes:
Drive in driving procedure driver, the data of steering wheel data acquisition unit Real-time Collection driver's direction of operating dish, and transfer data to vehicle mounted guidance terminal, the data of the driver's direction of operating dish currently gathered are contrasted to driver's normal operating custom on corresponding road conditions by vehicle mounted guidance terminal in conjunction with present road traffic information, when finding within a certain period of time to there is deviation always, can be determined that as driver currently for fatigue driving state, now driver can be sent alarm, the navigation of current road conditions can also be carried out sectional drawing and be easy to driver's fatigue analysis driving reason。
