Information.Similarly, when getting speed-limiting messages by navigation device, and not getting speed-limiting messages by camera, due to only
A speed-limiting messages are only got, therefore, equipment is controlled by the speed-limiting messages obtained by navigation device and is determined as target speed limit
Information.And when getting speed-limiting messages by camera and getting speed-limiting messages by navigation device, if passing through camera shooting
The speed-limiting messages that head obtains are identical as the speed-limiting messages obtained by navigation device, then illustrating obtain at this time two speed limit letters
Breath is accurate speed-limiting messages, therefore, can will be obtained the navigation information obtained by camera or by navigation device
Speed-limiting messages be determined as target speed-limiting messages；If by camera obtain speed-limiting messages with pass through navigation device obtain
Speed-limiting messages are not identical, illustrate the information that there is inaccuracy in the speed-limiting messages obtained at this time, and locating for speed-limiting messages and automobile
Environment is related, and therefore, control equipment is based on automobile current environment it needs to be determined that the environment that automobile is presently in, from logical
Cross the speed-limiting messages and pass through determining target speed-limiting messages in the speed-limiting messages that navigation device obtains that camera obtains.
Wherein, control equipment is based on automobile current environment, from the speed-limiting messages obtained by camera and by leading
It navigates and determines that the operation of target speed-limiting messages can be in the speed-limiting messages that device obtains are as follows: when the automobile current environment is specified
When environment, the speed-limiting messages obtained by the navigation device are determined as the target speed-limiting messages；When the automobile is presently in ring
When border is the environment except the designated environment, the speed-limiting messages obtained by the camera are determined as the target speed-limiting messages.
It should be noted that the designated environment is the living environments such as city, the environment except designated environment can be high speed
The meagrely-populated non-living environment such as highway, suburb.
Since designated environment is the living environments such as city, then network signal is usual when automobile is located in designated environment
Well, the speed-limiting messages that navigation device obtains are usually accurate speed-limiting messages, and since traffic mark is more in designated environment
Intensively, camera may acquire speed limit mark corresponding to the different roads of behaviour simultaneously, work as so that automobile can not be accurately determined
The speed-limiting messages of preceding place road.Therefore, when the automobile current environment is designated environment, the navigation device will be passed through
The speed-limiting messages of acquisition are determined as the target speed-limiting messages.Since the environment except designated environment is highway, suburb et al.
The non-living environment of cigarette rareness, farther out, camera is not easy one to distance to the speed limit mark on road less and between mark and mark
Secondary property acquires multiple speed limits marks, ensure that the accuracy of the speed limit mark of acquisition, and the network signal except non-designated environment
It is poor, cause navigation device to obtain speed-limiting messages difficulty, or the acquisition speed-limiting messages time is delayed, and the speed-limiting messages obtained are caused
It is inaccurate.Therefore, when the automobile current environment be the designated environment except environment when, will be obtained by the camera
Speed-limiting messages be determined as the target speed-limiting messages.
Further, since automobile is in moving condition, automobile local environment changes at any time, then passing through camera shooting
The speed-limiting messages navigation information identical, and will being obtained by camera as the speed-limiting messages obtained by navigation device that head obtains
Or after the speed-limiting messages obtained by navigation device are determined as target speed-limiting messages, the navigation information of camera acquisition and/
Or the speed-limiting messages of navigation device acquisition may change, after changing, control equipment needs to redefine target
Speed-limiting messages.
Wherein, it changes when the speed-limiting messages obtained by camera or by the speed-limiting messages that navigation device obtains
When, control, which identifies, determines automobile current environment；When automobile current environment be designated environment, and by camera acquisition
Speed-limiting messages change, when not changed by the information that navigation device obtains, the speed limit that will be obtained by camera
Information is determined as target speed-limiting messages, and the speed-limiting messages obtained by navigation device are determined as mesh after the first preset duration
Mark speed-limiting messages；It, will when automobile current environment is designated environment, and is changed by the speed-limiting messages that navigation device obtains
It is determined as target speed-limiting messages by the speed-limiting messages that navigation device obtains；When automobile current environment is except designated environment
Environment, and by camera obtain speed-limiting messages change when, the speed-limiting messages obtained by camera are determined as
Target speed-limiting messages；When automobile current environment be designated environment except environment, and pass through camera obtain speed limit letter
Breath does not change, when changing by the speed-limiting messages that navigation device obtains, detects the variation obtained by navigation device
Speed-limiting messages holding duration；When the holding duration of the speed-limiting messages of variation is greater than or equal to the second preset duration, will become
Speed-limiting messages after change are determined as target speed-limiting messages；The holding duration of speed-limiting messages after variation is less than the second preset duration
When, the speed-limiting messages obtained by camera are determined as target speed-limiting messages.
In one possible implementation, due to illustrating at automobile when automobile current environment is designated environment
In the living environments such as city, when the speed-limiting messages obtained by camera change, pass through the information that navigation device obtains
When not changing, since road is intensive in the living environments such as city, speed limit mark is also intensive, cause camera that may accidentally adopt
Collection causes speed-limiting messages to change, but may also be strictly that the road locating for the automobile leads to actual speed-limiting messages due to generation
Also it changes, therefore, in order to improve the accuracy of determining target speed-limiting messages, control equipment can will be obtained by camera
Speed-limiting messages be determined as target speed-limiting messages, the speed-limiting messages that then will be obtained by navigation device after the first preset duration
It is determined as target speed-limiting messages.
It should be noted that first preset duration can be arranged in advance, for example, first preset duration can be 40
Second, 80 seconds, 120 seconds etc..
In alternatively possible implementation, due to being the environment except designated environment when automobile current environment,
Illustrate that automobile is in the meagrely-populated environment such as highway, speed limit mark is less in these environment, and network signal is poor, takes the photograph
As logical produce of speed-limiting messages that head obtains is accurate speed-limiting messages.Therefore, when the speed-limiting messages obtained by camera become
Change, and no matter whether changed by the speed-limiting messages that navigation device obtains, control equipment will all be obtained by camera
Speed-limiting messages are determined as target speed-limiting messages.
In alternatively possible implementation, when automobile current environment is the environment except designated environment, and it is logical
The speed-limiting messages for crossing camera acquisition do not change, when being changed by the speed-limiting messages that navigation device obtains, due to vapour
Vehicle possible speed is too fast to cause camera that may not have enough time obtaining speed-limiting messages, but only navigation device gets limit
Fast information, but since the speed-limiting messages that navigation device obtains might not be accurate, control equipment needs to detect by leading
The holding duration of the speed-limiting messages for the variation that boat device obtains；When the holding duration of the speed-limiting messages of variation is greater than or equal to second
When preset duration, the speed-limiting messages after illustrating the variation that navigation device obtains are accurate speed-limiting messages, therefore, can be incited somebody to action
Speed-limiting messages after variation are determined as target speed-limiting messages；When the holding duration of speed-limiting messages after variation is default less than second
When long, the speed-limiting messages after illustrating the variation that navigation device obtains are therefore the speed-limiting messages of inaccuracy will be obtained by camera
The speed-limiting messages taken are determined as target speed-limiting messages.
It should be noted that second preset duration can be equally arranged in advance, for example, second preset duration can be
120 seconds, 80 seconds etc..
Step 303: control equipment is based on target speed-limiting messages and carries out speed limit reminding.
Wherein, control equipment directly can show speed-limiting messages by the instrument of automobile after determining target speed-limiting messages,
To carry out speed limit reminding, alternatively, since target speed-limiting messages may be the speed-limiting messages that camera is obtained from speed limit mark, because
This, control equipment can show that the target limits by the instrument of automobile when speed limit is identified and left in the acquisition range of camera
Fast information.
It should be noted that the speed-limiting messages can also be carried out language while displaying target speed-limiting messages by control equipment
Sound casting, to improve speed limit reminding efficiency.
In addition, control equipment can control instrument will when the target speed-limiting messages are the speed-limiting messages that camera obtains
After the target speed-limiting messages show third preset duration, terminate display.When the target speed-limiting messages are the limit that navigation device obtains
When fast information, which can be shown the 4th preset duration after the meeting by control equipment, terminate display.The third is default
Duration can be 120 seconds, 40 seconds etc..First preset duration can be equally arranged in advance, for example, the 4th preset duration can be with
It is 120 seconds, 100 seconds, 40 seconds etc..
Furthermore the current speed of automobile can also be compared by control equipment with target speed-limiting messages, when automobile is current
Speed be greater than target speed-limiting messages when, carry out overspeed prompting.
In embodiments of the present invention, control equipment can obtain speed-limiting messages by camera and navigation device, and according to
The quantity of automobile local environment and the speed-limiting messages of acquisition determines target speed-limiting messages, ensure that target speed-limiting messages are accurate
Speed-limiting messages, then target speed-limiting messages are shown by the instrument of automobile, to achieve the purpose that speed limit reminding, thus
