Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a lane guidance method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
the lane guiding method provided by the embodiment of the invention is mainly applied to navigation products and used for assisting navigation. Specifically, the preset lane attribute is an attribute defined in advance for a lane.
For example, in the present embodiment, the preset lane attributes may include entering a parking lot, entering a gas station, a time-limited bus lane, a water accumulation-prone lane, and the like. Other attributes for identifying lane transit speed when in a congested state may also be included.
In an optional embodiment, the preset lane attribute may include an attribute generated according to basic lane information and a Point of Interest (POI), and may also include a lane attribute actively set by a user. For example, the attributes of a lane entering a parking lot, entering a gas station and the like can be determined according to interest points of hospitals, scenic spots, shopping malls, gas stations and the like in the map data; the time-limited bus lane can be determined according to the limited travel time of the bus lane in the map data. The user can actively set the lane at the position to be in the ponding state according to the driving state of the lane, so that the attribute of the lane easy to ponding is determined.
In the navigation process, after the user determines the navigation planning path recommended by the navigation system, the preset lane attributes of each lane on the navigation planning path can be acquired.
in this embodiment, the congested link refers to a road congestion or a slow vehicle traveling, and the congestion degree can be determined according to a speed of the vehicle traveling and a length of the congestion. It should be understood that the congestion degree of the congested road section is not further limited herein. Specifically, the congestion section may be congestion generated when the navigation planned path is generated, or may be congestion generated during navigation.
And when the congested road section exists, judging whether the congested road section has a first target lane with the preset lane attribute according to the acquired preset lane attribute. Specifically, the congested road segment may include one or more first target lanes, and the preset lane attributes of different first target lanes are the same or different.
In this embodiment, the ideal traveling speed of each lane in the congested road segment may be determined according to the preset lane attribute of the first target lane, so as to determine a lane that is preferentially traveled.
The method comprises the steps of obtaining a preset lane attribute of a navigation planning path, wherein the preset lane attribute is used for marking the attribute of lane passing speed when the navigation planning path is in a congestion state; when a congestion road section exists in the navigation planning path, judging whether the congestion road section has a first target lane with the preset lane attribute; when the congested road section has a first target lane with the preset lane attribute, determining a priority driving lane according to the lane position of the first target lane. Therefore, the user can drive according to the priority driving lane, and the driving speed of the congested road section is improved. Therefore, the implementation of the invention improves the navigation capacity of the congested road section.
Specifically, the preset lane attribute may be classified according to a lane passing speed in a congestion state, for example, in this embodiment, the preset lane attribute is a first target attribute or a second target attribute;
when the preset lane attribute is a first target attribute, the ideal passing speed of the first target lane is lower than that of the second target lane;
when the preset lane attribute is a second target attribute, the ideal passing speed of the first target lane is greater than that of the second target lane;
for example, in an alternative embodiment, the above described entry into a parking lot, entry into a gas station, and easy water spot lane may be considered as the first target attribute. As shown in fig. 2, if a certain road segment is on a road with two lanes in one direction, and if a parking lot of a certain mall or hospital exists in the right lane, an external vehicle can enter the parking lot from the right lane. At this time, when too many vehicles queue into the parking lot, congestion on the road section will easily occur. In this case, since the right lane is often vehicles that are queued to enter the parking lot, the communication speed of the left lane is ideally higher than the communication speed of the right lane.
For example, in another alternative embodiment, the time-limited bus lane described above may be considered as the second target attribute. As shown in fig. 3, a certain road segment is on a lane that is three lanes in one direction. The right side is a time-limited bus lane, the vehicle usually runs through the left side lane and the middle lane when the vehicle normally runs, people avoid violation of regulations or run on the left side lane and the middle lane as much as possible when congestion occurs on the road, and at the moment, the passing speed of the right side lane is higher than that of the left side lane and the middle lane under an ideal state.
Further, the selected priority driving lane is different for different preset lane attributes. This is explained in detail below:
in an optional embodiment, when the preset lane attribute is a first target attribute, the priority driving lane is a lane farthest from the first target lane in the second target lane;
as shown in fig. 2, the left lane is the second target lane, the right lane is the first target lane, and the priority travel lane is the second target lane. Specifically, when there are a plurality of second target lanes, the priority travel lane is a lane farthest from the first target lane. Therefore, the temporary lane change of the vehicle of the first target lane can be avoided, and the driving speed of the second target lane which is closer to the first target lane is slower.
In another optional embodiment, when the preset lane attribute is the second target attribute, the priority driving lane is the first target lane, and at this time, a corresponding prompt message is displayed on the navigation interface as shown in fig. 2.
As shown in fig. 3, the left lane and the middle lane are the second target lanes, the right lane is the first target lane, and at this time, the priority driving lane is the first target lane, and at this time, the corresponding prompt information is displayed on the navigation interface as shown in fig. 3.
Further, based on the above embodiment, the preset attribute further includes an attribute validation condition; when a congested road section exists in the navigation planning path, the step of judging whether the congested road section has a first target lane with the preset lane attribute comprises the following steps:
and when the navigation planning path has a congested road section and the lane attribute condition is effective, judging whether the congested road section has a first target lane with the preset lane attribute.
The above-described attribute validation condition is used in the present embodiment to determine whether the preset lane can be validated. The time-limited bus lane and the lane prone to water accumulation are taken as examples for explanation.
For example, in an alternative embodiment, when there is a water accumulation prone lane in a certain road section, the attribute valid condition is rain. If the current weather is rainy, the attribute of the lane easy to accumulate water takes effect; if the current weather is not rainy, the attribute of the easy ponding lane is not valid.
Specifically, if the road section is jammed in rainy days, determining that a first target lane with the preset lane attribute exists in the road section; and if the road section is congested on rainy days, determining that the first target lane with the preset lane attribute does not exist in the road section.
In another optional embodiment, when a limited time bus lane exists in a certain road segment, the attribute effective condition is a non-limited time interval. If the current time is a non-time-limited interval, the attribute of the time-limited bus lane takes effect; and if the current weather is not rainy, the attribute of the time-limited bus lane is not effective.
Specifically, if the current time is a non-limited interval and the road section is congested, determining that a first target lane with the preset lane attribute exists in the road section; and if the current time is a time-limited interval and the road section is congested, determining that the first target lane with the preset lane attribute does not exist in the road section.
In this embodiment, by adding the attribute non-validation condition, the accuracy of the priority travel lane recommendation can be improved.
Further, in this embodiment, after the priority driving lane is determined, a finer-grained broadcast may be performed. Specifically, after determining the priority driving lane according to the lane position of the first target lane, the method further includes:
and outputting voice prompt information, wherein the voice prompt information comprises the attribute of the first target lane and/or the lane information of the priority driving lane.
For example, the broadcasting mode of the voice prompt message may be set according to actual needs, and in an optional embodiment, the attribute of the first target lane may be broadcasted. Specifically, the played voice may be "the nth lane in front is the XXX attribute lane".
In another optional embodiment, the user can be reminded of changing to the preferential driving lane at the same time, and reasonable congestion avoidance is carried out. Specifically, the played voice may be "the nth lane in front is the XXX attribute lane, please go the XXX lane".
It should be noted that a traffic weight may also be defined for each preset lane attribute, and when more than two first target lanes exist in a certain congested road segment, the traffic weight of the first target lane may be calculated, so as to finally determine a priority driving lane.
According to the embodiment of the invention, the attribute of the first target lane and/or the lane information of the priority driving lane are/is reminded through the language prompt information, so that the user can be guided to drive to the lane which is fast to pass through, the waiting time of the user is reduced, the user can fast pass through the congested road section, the traffic pressure is greatly relieved, and the convenience of traveling is enhanced.
It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
