Description
Technical field
The invention belongs to car speed control field, specifically a kind of vehicle safety active control side based on road information
Method.
Background technology
The urban road and highway in China have speed limit, and the traffic accident caused due to overspeed of vehicle every year all occupies
A big chunk ratio has overspeed of vehicle a specific punishment regulations in traffic law.When driver wants in driving procedure
It carves and pays attention to speed instrument board, prevent overspeed driving car, but driver does not notice the speed-limiting messages of road sometimes,
It is easy to exceed the speed limit in the case that scatterbrained, on the market have much prevents the device of overspeed of vehicle, such as have super at present
The cyberdog of fast early warning, but there is a situation where to report by mistake and fail to report, and part cyberdog is also forbidden using in the car；Also there is vapour
Vehicle is equipped with constant speed cruising system, needs manual setting cruise speed per hour, although can be effectively prevented from driving over the speed limit, operation
It is cumbersome, easily disperse driver attention, especially in multistage speed limit roadways, even if being equipped with the automobile of constant speed cruising system
It also happens occasionally there is a situation where exceeding the speed limit.
Invention content
The purpose of the present invention is to provide a kind of vehicle safety Active Control Methods based on road information.
Realize that technical solution of the invention is：A kind of vehicle safety Active Control Method based on road information, tool
Body step is：
Step 1 obtains current vehicle travel speed V and the road information where current vehicle in real time；
Step 2, according to road information, calculate automobile maximum travelling speed threshold value Vm, specially：
Vm=road speed limit × (1+5%)
Step 3, by automobile maximum travelling speed threshold value VmIt is compared with present speed V, phase is sent according to comparison result
To ECU, the driving instruction according to comparison result transmission is specially the driving instruction answered：
1) when real-time vehicle velocity V is more than automobile maximum travelling speed threshold value VmWhen, pressure control car deceleration is sent out to VmTraveling
Instruction；
2) when real-time vehicle velocity V is less than or equal to automobile maximum travelling speed threshold value Vm, restricting vehicle maximum raises speed to Vm。
Step 4, ECU control the gait of march of vehicle and in the form of voice broadcast to driver in response to driving instruction
Report current transport condition.
Compared with prior art, the present invention its remarkable advantage is：
(1) present invention is by obtaining real-time speed and road information, solves the existing wrong report of vehicle electronics dog, fails to report
Problem, data reliability higher are highly practical；
(2) present invention sets the maximum traveling speed of automobile with reference to road information automatically without manually inputting the speed limit of automobile
Degree realizes the automation of automobile speed limit control, and in the road of multistage speed limit, it is multiple to solve vehicle-mounted constant speed cruising system operation
It is miscellaneous so that driver can more focus on；
(3) present invention can be applicable on any automobile, and can play prevents overspeed of vehicle, and reduction is driven over the speed limit to driver
The harm brought improves the purpose of drive safety.
Description of the drawings
Fig. 1 is the algorithm flow schematic diagram of the present invention.
Fig. 2 is the structure composition schematic diagram of the present invention.
Specific embodiment
As shown in Figure 1, a kind of vehicle safety Active Control Method based on road information, the specific steps are：
Step 1 obtains current vehicle travel speed V and the road information where current vehicle, the road information in real time
Specially road limitation speed；In the present embodiment, real-time vehicle velocity V is obtained by vehicle speed sensor；Current vehicle in the present embodiment
The road information at place mainly passes through vehicle GPS positioning and the position where the current automobile of machine vision technique acquisition and limit
Fast information, and combining position information reads category of roads in category of roads and speed-limiting messages database, speed limit.
Step 2, according to road information, calculate automobile maximum travelling speed threshold value Vm, it is contemplated that the positioning accuracy and speed of GPS
The problems such as spending sensor transmissions precision, there is provided ± 5% error amount, maximum travelling speed threshold value VmSpecially：
Vm=road speed limit × (1+5%)
Step 3, by automobile maximum travelling speed threshold value VmIt is compared with present speed V, phase is sent according to comparison result
To ECU, the driving instruction according to comparison result transmission is specially the driving instruction answered：
1) when real-time vehicle velocity V is more than automobile maximum travelling speed threshold value VmWhen, pressure control car deceleration is sent out to VmTraveling
Instruction；
2) when real-time vehicle velocity V is less than or equal to automobile maximum travelling speed threshold value Vm, restricting vehicle maximum raises speed to Vm。
Step 4, ECU control the gait of march of vehicle and in the form of voice broadcast to driver in response to driving instruction
Report current transport condition.In the present embodiment, control car deceleration is forced to pass through ECU to adjust the aperture of air throttle come real
It is existing.
Road information is constantly obtained in vehicle travel process, repeats step 1~4, ensures driving safety.
It is real to obtain current automobile by ECU in real time for the vehicle safety Active Control Method based on road information of the present invention
When speed, compared by GPS positioning and category of roads and speed limit database, machine vision technique intelligent recognition road speed limit
The mode of information, the automatic threshold value for setting automobile maximum travelling speed, overspeed of vehicle is prevented so as to reach, and effectively improves road friendship
Lead to the purpose of safety.
