If the traffic information does not meet sets requirement, blind area monitoring function is not started；
3) speed signal of simulating vehicle input is received, if the speed in the speed signal is more than or equal to minimum setting speed
It is poly- 4) then to enter step for degree, if speed does not start blind area monitoring function lower than minimum setting speed；
4) start blind area monitoring function, and judge whether there is object and enter target area, target level is judged if having
In the position of simulating vehicle, and enter step 5)；
5) judge that object at a distance from simulating vehicle and the speed of object, is wanted if object speed meets setting simultaneously
It asks, the blind area monitoring function issues alarm signal.
The traffic information refers to that road is the radius of straight way or bend and bend, and the radius information of bend is logical
Cross the judgement of steering wheel angle information.
The object is at least automobile, motorcycle, bicycle or pedestrian.
The position that the object is located at simulating vehicle includes positioned at the left back or right back of vehicle described in mould.
Step 4) further includes the type for receiving confirmation signal to confirm object, when the object is vehicle, into step
It is rapid 5).
The step 5) is specifically, object monitors in region at a distance from simulating vehicle in blind area, and is more than or equal to and sets
When set a distance, the judgement of object speed is carried out, if the speed of object is less than or equal to setting speed, blind area monitoring function is not sent out
Alarm signal out；
If the speed of object is greater than setting speed, the blind area monitoring function issues alarm signal；
Object at a distance from simulating vehicle in the monitoring region of blind area, and when being less than set distance, blind area monitoring
Function issues alarm signal.
The setting speed is less than or equal to simulating vehicle speed.
The alarm signal passes to UI interface display.
The beneficial effects of the present invention are:
The technical program is carried out function according to design of product function product function logic chart, using Simulink software
Modelling, model can carry out the related data for virtual vehicle, virtual-sensor and the virtual scene that simulation software provides blind
The detection of area's warning function, and then realize the functional verification of blind monitoring control system.

Specific embodiment
Carry out the technical solution that the present invention will be described in detail by the following examples, embodiment below is merely exemplary, only
It can be used to explanation and illustration technical solution of the present invention, and be not to be construed as the limitation to technical solution of the present invention.
The application is taken according to BSD (blind monitoring control system) product function and system performance by Simulink software
System model is built, by software emulation, the virtual vehicle, virtual-sensor and the virtual scene that are provided with software, and will be related
Data are sent to Simulink model, and Simulink model carries out decision to analogue data, and the result of decision is in user interface
Upper display.
As shown in Figure 1, rear looking radar is monitored the driver's field of vision blind area of this vehicle behind side, when there is vehicle to appear in this
Region and when meeting alert if, will make alarm, blind area monitoring function alarm region is as shown in Figure 1 to driver.
A kind of blind monitoring control system model design method, comprising: the starting of blind area monitoring function and blind area monitoring function
Alarm, wherein blind area monitoring function starts, forbids condition and alarming logic as shown in Figures 2 to 6.
For realize signal normal solution transmission, build such as Fig. 5 judge blind area monitoring function Boot Model, according to speed, gear,
Steering wheel angle signal come judge speed, gear and road conditions whether meet blind area monitoring function starting Simulink model.
1) gear signal of simulating vehicle input is received, and is judged；
If the gear signal is forward, step 2) is carried out, if gear signal is non-forward, is not started
Blind area monitoring function；When the non-forward range of the application includes reverse gear, neutral gear, parking gear, blind area monitoring function is forbidden.
2) traffic information of simulating vehicle input is received, the traffic information of the application refers to that road is straight way or bend,
And the radius of bend, and the radius information of bend is judged by steering wheel angle information, if the traffic information meets setting
It is required that then entering step 3), if the traffic information does not meet sets requirement, blind area monitoring function is not started.
3) speed signal of simulating vehicle input is received, if the speed in the speed signal is more than or equal to minimum setting speed
It is poly- 4) then to enter step for degree, if speed does not start blind area monitoring function lower than minimum setting speed.
The target vehicle coherent signal that Simulink model is sended over according to simulation software has first carried out simple process (such as
Conversion of measurement unit), judge whether to meet alert if further according to function logic, as shown in Figure 6.
4) start blind area monitoring function, and judge whether there is object and enter target area, target level is judged if having
In the position of simulating vehicle, and enter step 5)；The object does not refer to automobile singly, can also be motorcycle, electric vehicle, voluntarily
The movements such as vehicle, pedestrian, animal can be static in order to further exclude to the target that traffic threatens, Yao Jinhang object judgement
Barrier and noise jamming；The position that the object is located at simulating vehicle includes behind the left back or the right side of vehicle described in mould
Side.
Step 4) further includes the type for receiving confirmation signal to confirm object, when the object is vehicle, into step
It is rapid 5).
5) judge that object at a distance from simulating vehicle and the speed of object, is wanted if object speed meets setting simultaneously
It asks, the blind area monitoring function issues alarm signal.
The step 5) is specifically, object monitors in region at a distance from simulating vehicle in blind area, and is more than or equal to and sets
When set a distance, the judgement of object speed is carried out, if the speed of object is less than or equal to setting speed, blind area monitoring function is not sent out
Alarm signal out；
If the speed of object is greater than setting speed, the blind area monitoring function issues alarm signal；
Object at a distance from simulating vehicle in the monitoring region of blind area, and when being less than set distance, blind area monitoring
Function issues alarm signal.
The setting speed is less than or equal to simulating vehicle speed.
The alarm signal passes to UI interface display, can carry out intuitive judgment to simulation result.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And deformation, the scope of the present invention is by appended claims and its equivalent limits.
