Embodiment
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Present embodiments provide a kind of method of intelligent navigation, as shown in Figure 1, comprise step:
The speed of a motor vehicle of step S100, Real-time Obtaining driving.In the present embodiment, be before driving arrives crossing to the acquisition of the speed of a motor vehicle, because the speed of a motor vehicle is constantly change, so need to carry out in real time to the collection of the speed of a motor vehicle, ensuing intelligent navigation operation could be carried out according to the difference of the speed of a motor vehicle like this.
Step S200, according to the speed of a motor vehicle obtained in step S100, determine its place velocity range, search corresponding displaying ratio, automatically to determine the corresponding engineer's scale of navigation map according to described velocity range.
When determining velocity range, first to set a reaction time, according to this reaction time computing velocity scope.Before driving arrives crossing, time enough must be left make a response to junction ahead for vehicle, owing to driving a vehicle, itself there is certain speed, so also should determine according to the speed of a motor vehicle of reality when setting the reaction time, in the present embodiment, the reaction time is set as 20s, use the display screen of 6.2 cun, because the display screens of 6.2 cun only have 4 engineer's scales available, so association reaction time and the speed of a motor vehicle, get final product computing velocity scope and determine corresponding navigation map engineer's scale.
Concrete result of calculation is as shown in the table:
Wherein, the actual speed of vehicular speed representative driving, distance representative per second is according to the real-time speed of a motor vehicle, the actual range of traveling per second of driving a vehicle, the display screen that numeral 4 under 6.2 cun of screens represents 6.2 cun only has 4 engineer's scales selective, digitized representation below each engineer's scale is according to the real-time speed of driving, from current location to from crossing out, the reaction time needed, because the reaction time of setting is 20s, 20s must be greater than by the time needed for crossing, so can draw according to the data in above-mentioned table, the velocity range of driving and the navigation map engineer's scale corresponding with velocity range, be specially:
When the velocity range of driving a vehicle is 0-10km/h, corresponding navigation map engineer's scale is 1:25m;
When the velocity range of driving a vehicle is 10-30km/h, corresponding navigation map engineer's scale is 1:50m;
When the velocity range of driving a vehicle is 30-70km/h, corresponding navigation map engineer's scale is 1:100m;
When the velocity range of driving a vehicle is 70-140km/h, corresponding navigation map engineer's scale is 1:200m;
When the velocity range of driving a vehicle is more than 140km/h, corresponding navigation map engineer's scale is 1:400m.
Owing to usually can not be greater than 140km/h in driving by speed during crossing, engineer's scale 5 belongs to extreme situation, and 6.2 cun of screens only show front 4 engineer's scales, and comparative example chi 5 does not show, and lists engineer's scale 5 just in order to calculate needs in table.
Because the reaction time is situation according to driver and fixed, so the reaction time is not limited to the 20s of the present embodiment, for the new hand that some are driven, may be slow a little to the judgement meeting of road conditions, it is longer that the corresponding reaction time also can set, such as 25s, 30s's and so on, this is determined according to the actual conditions of user.
Step 300, guider are according to the automatic show navigator map of the engineer's scale drawn in step 200.Velocity range and corresponding navigation map engineer's scale have system to calculate voluntarily, if as above-mentioned in this enforcement is set as 20s in the reaction time, then corresponding navigation map engineer's scale all also just determines, after obtaining the actual speed of driving a vehicle, system all can judge the navigation map engineer's scale corresponding to this speed automatically, and the navigation map of this engineer's scale is demonstrated by display screen, the actual speed such as recording driving is 50km/h, then navigation map just shows according to the engineer's scale of 1:50m, actual speed is 100km/h, then navigation map just shows according to the engineer's scale of 1:200m.
By the method for the present embodiment, according to the actual speed of driving, navigation map can adjust suitable engineer's scale automatically, has accomplished to drive a vehicle by intelligent decision during crossing, makes the display of navigation map more be applicable to the demand of driver.
Based on the method for above-mentioned intelligent navigation, present invention also offers a kind of system of intelligent navigation, as shown in Figure 2, comprising: speed of a motor vehicle acquisition module 21, judge module 22 and display module 23;
Wherein, speed of a motor vehicle acquisition module 21, for the speed of a motor vehicle of Real-time Obtaining driving;
Judge module 22, for the speed of a motor vehicle obtained according to speed of a motor vehicle acquisition module 21, determines its place velocity range, searches corresponding displaying ratio, automatically to determine the corresponding engineer's scale of navigation map according to described velocity range;
Display module 23, the automatic show navigator map of the navigation map engineer's scale for determining according to judge module 22.
In the device described in the embodiment of the present invention, as shown in Figure 3, described judge module 22 also comprises:
Velocity range setting unit 221, for the reaction time according to default, determines the velocity range of driving a vehicle;
Engineer's scale setting unit 222, the velocity range for determining according to velocity range setting unit determines corresponding navigation map engineer's scale.
To sum up, the method and system of intelligent navigation provided by the invention, by in setting one reaction time, according to the real-time speed of a motor vehicle obtained, calculate vehicle speed range, and determine the engineer's scale of corresponding navigation map, like this when driving a vehicle by crossing, the engineer's scale of navigation map that can be suitable according to the also automatic adjustment that the speed of a motor vehicle is real-time, the enough reaction time is reserved to user, make correct driving to crossing above to judge, avoid missing crossing to detour the generation of problem, the use of person easy to use, and this invention is simple, cost of development is very low, be applicable to large-scale production and use.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
