Problems solved by technology

However, the inventor found in the process of realizing the invention that the driving route pushed by the electronic map when the user sets off is only suitable for the road conditions when the user sets off, and there are some shortcomings in the whole journey of the user following the driving route pushed by the electronic map at the time of departure, which is specifically manifested as : First, when the navigation route is congested, the user continues to drive according to the navigation route, resulting in longer driving time, which not only increases driving fatigue, but also disrupts the travel plan; The road conditions of the route change in real time. When the road conditions outside the user's driving route are smooth, the user needs to manually query and switch the driving route while driving, which reduces the driving efficiency and increases the risk of safety accidents

no. 1 example

[0031] figure 1 It is a flow chart of the method for updating the navigation route according to the first embodiment of the present invention. like figure 1 As shown, the method for updating the navigation route provided by this embodiment can be implemented through the following steps.

[0032] Step S110, calculating multiple driving routes of the vehicle from the current location to the preset location in real time. In this step, the terminal obtains the preset location of this trip through the user's manual input or the preset location coordinates, and obtains the current location of the vehicle in real time through the user's manual input or the built-in positioning module. The terminal matches the pre-stored navigation data according to the obtained current location and the preset location, and calculates multiple driving routes from the current location to the preset location according to the navigation data. The terminal device may be a car entertainment device, a mo...

[0038] figure 2 It is a flowchart of the method for updating the navigation route according to the second embodiment of the present invention. like figure 2 As shown, step S130 can be implemented through the following methods.

[0039] Step S131, calculating the driving distance of each driving route. The terminal obtains the electronic route tracks of multiple driving routes, and measures the length of the electronic route of each driving route through the built-in distance measurement tool. Subsequently, the terminal retrieves the ratio value of the length of the electronic route to the length of the actual route from the pre-stored database, and calculates the actual driving distance of each driving route according to the ratio value and the length of the electronic route.

[0040] Step S132, calculating the driving time of each driving route according to the road condition information and the driving distance. On the basis of step S131, the terminal only needs to cal...

[0048] image 3 It is a flowchart of the method for updating the navigation route according to the third embodiment of the present invention. like image 3 As shown, on the basis of the first embodiment, the method for updating the navigation route can also be implemented according to the following steps.

[0049] Step S110, step S110 has been introduced in the first embodiment, and will not be repeated here.

[0050] Step S121, acquiring the number of signal lights on each driving route. The terminal sends multiple driving routes to the traffic condition server. After the traffic condition server recognizes each driving route, it retrieves the number of signal lights on each driving route, so that each driving route corresponds to the number of signal lights one by one and then sends it to the terminal superior.

[0051] Step S134, among the plurality of driving routes, select the driving route with the least number of traffic lights as the first route. The terminal sort...

Abstract

The embodiment of the invention discloses a navigation route updating method and device. The navigation route updating method comprises the following steps: calculating multiple drive routes of a vehicle from the current position to a preset position in real time; acquiring road condition information on each drive route; selecting a first route from multiple drive routes according to the road condition information; and updating a navigation route according to the first route. The navigation route updating device accordingly comprises a route calculating module, a road condition acquisition module, a route selecting module and an updating module. By adopting the navigation route updating method and device which are provided by the invention, the drive route is updated in real time, and thedrive route is switched timely when the drive route is jammed or other routes are smooth, so that the driving efficiency is improved, the driving time is shortened, the driving fatigue is reduced, andthe driving security is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle intelligent control, and in particular to a method and device for updating a navigation route. Background technique [0002] Currently, electronic maps are widely used in mobile applications or desktop applications. As long as the network supports, people can check the electronic map anytime and anywhere to find the destination they want to reach. The current traffic conditions can be displayed on the electronic map, for example, green represents a smooth road section, yellow represents a slow-moving road section, and red represents a congested road section. When people travel by car, referring to the traffic conditions displayed on the map, on the one hand, they can have a certain time expectation for the trip, and on the other hand, they can choose a relatively smooth route to a certain extent to avoid congestion. [0003] In the prior art, the electronic map can determin...
