Embodiments of the present disclosure provide a navigation method for implementing safe navigation and a navigation system capable of applying the method. The method includes determining a navigation plan; acquiring the current geographic position of a target object; determining the position of the target object in the electronic map based on the acquired geographic position; acquiring environmental condition information of the current surrounding environment of a target object; and determining a navigation strategy of the electronic navigation software based on the environmental condition information and the position of the target object in the electronic map to arrange or change the determined navigation plan.

Fig. 1 schematically shows an application scenario of a navigation method and a navigation system according to an embodiment of the present disclosure.

As shown in fig. 1, the present disclosure may be applied to any scene such as in-vehicle navigation and live-action navigation by electronic navigation software. Specifically, a navigation plan can be preset by means of an electronic map, the real-time environment condition of the surrounding environment is concerned in the advancing process according to the existing navigation plan, and the corresponding navigation strategy is designated to arrange or change the existing navigation plan, so that the mechanical navigation without live situation can be avoided, and safe navigation and flexible navigation are realized.

Fig. 2 schematically shows a flow chart of a navigation method according to an embodiment of the present disclosure.

As shown in fig. 2, the method includes operations S210 to S250.

In operation S210, a navigation plan is determined.

Specifically, an origin and a destination may be entered, with electronic navigation software providing one or more possible navigation plans for selection by the user.

In operation S220, a geographic location where the target object is currently located is acquired.

The target object is matched with the actual application scene, for example, when the vehicle is in navigation, the target object is a vehicle, and when the real scene is in navigation, the target object is a user.

In operation S230, a location of the target object in the electronic map is determined based on the acquired geographic location.

Namely, the current geographic position of the target object is mapped into a pre-established electronic map.

In operation S240, environmental condition information of the surrounding environment in which the target object is currently located is acquired.

Specifically, the environmental conditions may include, but are not limited to, environmental conditions due to construction, weather, traffic, and daily life.

For example, garbage due to construction, roadblocks due to construction, and the like; for example, water accumulation, landslide, traffic accident scene, etc. due to weather; for another example, people flow, traffic flow, accident scene, etc. caused by traffic jam; and for example, garbage due to daily life.

In operation S250, a navigation strategy of the electronic navigation software is determined based on the environmental condition information and the position of the target object in the electronic map to arrange or change the determined navigation plan.

Specifically, a more flexible navigation strategy may be determined with reference to the actual environmental conditions around the target object on the basis of navigating according to the position of the target object mapped in the electronic map, to decide how to navigate based on the determined navigation plan next.

For example, taking the car navigation as an example, if the environment live represents a red light ahead, the driver is prompted to pause waiting for the red light ahead, if the environment live represents a green light ahead, the driver is prompted to continue to move ahead by the green light ahead, if the environment live represents an obstacle ahead, the navigation plan is modified or reset according to the actual situation, and the like.

For another example, taking live-action navigation as an example, if the environment live represents a red light ahead, the user is prompted to pause waiting for the red light ahead, if the environment live represents a green light ahead, the user is prompted to continue to move ahead, if the environment live represents a vehicle driving ahead, the user is prompted to wait or slow down, and so on.

Do not consider when navigating with prior art completely current environmental situation, break through the red light easily, cause the traffic accident easily and compare, through the embodiment of this disclosure, can consider current environmental situation during the navigation, avoid breaking through the red light, avoid causing the traffic accident for it is safer, more nimble to navigate.

The method shown in fig. 2 is further described with reference to fig. 3A-3D, and fig. 4A-4B, in conjunction with specific embodiments.

As an alternative embodiment, the determining the navigation strategy of the electronic navigation software to arrange or change the navigation strategy of the electronic navigation software includes: and when the environmental condition information indicates that the current environmental condition meets the preset characteristics, executing one or more of the following A-E.

A: the determined navigation plan is kept unchanged and a pause is prompted at the current navigation position or a pause is prompted in the vicinity of the current navigation position a predetermined time ahead.

For example, as shown in fig. 3A, in the process of advancing according to the determined navigation plan, when the camera detects that the front is blocked due to rain and snow weather (such as a heavy snow-covered road, deep ponding, landslide, debris flow, and the like), if the camera continues to navigate according to the navigation plan determined in advance, the target object is likely to enter a dangerous area, even a safety accident occurs, and therefore, in such a situation that the temporary no-way can be cleared, the determined navigation plan can be kept unchanged, but the navigation progress of the navigation software needs to be controlled to be paused at the current navigation position, and the target object is paused until the front blocking is released, or the navigation progress of the navigation software is controlled to be paused near the current navigation position in advance by a predetermined time, so that sufficient time can be reserved to prompt the stop in advance.

B: and keeping the determined navigation plan unchanged, and prompting to continue to navigate according to the navigation plan after delaying for a period of time at the current navigation position, or prompting to continue to navigate according to the navigation plan after delaying for a period of time near the current navigation position in advance by a preset time.

For example, as shown in fig. 3B, in the process of advancing according to the determined navigation plan, when the camera detects a red light ahead or a pedestrian (e.g., a large snow-covered road, deep ponding, a landslide, a debris flow, etc.), in order to avoid running the red light or avoiding the pedestrian, the determined navigation plan may be kept unchanged, but the navigation progress of the navigation software needs to be controlled to pause at the current navigation position until a green light or the pedestrian passes, and then the navigation is continued according to the previously determined navigation plan, or a predetermined time is advanced to prompt the driver to stop after a time delay near the current navigation position, so that sufficient time may be reserved to prompt the driver to stop in advance.

C: on the basis of the determined navigation plan, the navigation plan at the specified navigation position is modified, or the navigation plan at the specified navigation position is modified and a predetermined time ahead is used for prompting that part of the navigation plan is modified.

For example, as shown in fig. 3C, in the process of advancing according to the determined navigation plan, when the camera detects that a front turn is being constructed and the construction area is small, if the navigation is continued according to the previously determined navigation plan, it is highly likely that a constructor or a construction device is collided, and in order to avoid the turn, the previously determined navigation plan needs to be finely adjusted, for example, a small turn is directly turned before, and a large turn can be turned around. Alternatively, the driver may be informed that a portion of the navigation plan has been modified a predetermined time in advance while the navigation plan at the specified navigation location has been modified, so that sufficient time can be left for the driver to prompt the driver for exit, turns, merge, etc.

D: and resetting the subsequent navigation plan from the designated navigation position, or resetting the subsequent navigation plan and prompting that part of the navigation plan is reset in advance by a preset time.

For example, as shown in fig. 3D, in the process of proceeding according to the determined navigation plan, when the camera detects that a front turn is being constructed and the construction area is large, if the navigation is continued according to the predetermined navigation plan, it is highly likely to hit a constructor or a construction equipment, and if the navigation plan determined in advance is only finely adjusted, the construction site cannot be bypassed, in this case, it is necessary to start at the specified navigation position in front, and reset the subsequent navigation plan, for example, a small turn needs to be directly turned before, and at this time, the route can be adjusted to go straight ahead.

In addition, for the cases of A-D, corresponding voice prompts can be added simultaneously so as to attract the attention of the driver, and furthermore, the voice prompts can be continuously prompted for a plurality of times for one event, so that the voice prompts can attract the attention of the driver.

In addition, for the cases of a to D, in some navigation scenarios, especially in-vehicle navigation, it is likely that the driver or the user cannot be noticed only by making a navigation strategy arrangement or changing a determined navigation plan, and in order to overcome this drawback, a voice prompt or a visual prompt may also be output at the same time.

E: and outputting voice prompt or visual prompt aiming at the determined navigation plan.

For example, the front is a school, and the driver may be prompted to slow down for a determined navigation plan, or to skid on a rainy or snowy day, or to slow down for a determined navigation plan, etc.

By the embodiment of the disclosure, different navigation strategies can be formulated according to different environmental conditions, and then the navigation plan which is determined in advance is arranged or changed based on the navigation strategies, so that safety accidents possibly caused by simple mechanical navigation are overcome, and finally, the aim of flexible and safer navigation is fulfilled.

As an alternative embodiment, the environmental condition information includes, but is not limited to, one or more of the following: environmental condition information caused by weather conditions, such as severe water accumulation on roads caused by heavy rain, partial road section collapse, hillside debris flow, traffic accidents, and the like; the condition information of the surrounding road surface, wherein the condition information of the surrounding road surface may specifically include information about a stationary object and/or information about a moving object. Further, the information related to the stationary object may include traffic light information, road block information, other obstacle information such as road debris; the information related to the moving object may include information of pedestrians, vehicles, and the like.

As an optional embodiment, the method further includes determining whether the current environmental condition satisfies the predetermined characteristic, and the operation may include at least two implementations:

mode 1: as shown in fig. 4A, operations S410 to S430 are included:

operation S410 of acquiring an image about a surrounding environment;

operation S420, identifying one or more identified objects in the image; and

operation S430 predicts whether the current environmental condition satisfies a predetermined characteristic according to the identified identifying object.

It should be noted that the identification object may be predetermined, and may include, but is not limited to, a vehicle, a person, a traffic sign (e.g., a signal, a road sign, etc.), and the like.

For example, in the case of vehicle-mounted navigation, if a child (i.e., an identifiable object) in the surrounding environment is approaching the vehicle during driving of the target object of the vehicle, even if the child is currently in front of the vehicle and is approaching the vehicle on a sidewalk in a direction parallel to the driving direction of the vehicle, although there is no safety risk, in order to reduce the safety risk, the motion trajectory attribute of the child may be predicted according to the characteristics of the child and the prediction result may be used as a part of the current environmental condition to make a corresponding navigation strategy, so as to arrange or change the predetermined navigation plan.

For another example, continuing to take the car navigation as an example, if a garbage bag in the surrounding environment captured by the camera flies head-on during the driving of the target object of the vehicle, but considering that even if the garbage bag collides with the vehicle, no safety accident will be caused, the environmental condition information can be ignored at this time, and the navigation is continued directly according to the predetermined navigation plan.

Mode 2: as shown in FIG. 4B, operations S440-S450 are included:

an operation S440 of sensing, by a sensing device, stationary objects in a surrounding environment, and/or moving objects; and

in operation S450, it is determined whether the current environmental condition satisfies a predetermined characteristic according to the relative displacement relationship between the sensed object and the target object.

The relative displacement relationship includes, but is not limited to, a relative position relationship and a relative velocity relationship.

It should be noted that, since the sensor can only identify the relative position relationship or the relative displacement relationship between the object and the target object in the surrounding environment, and cannot identify what the object is, and even cannot predict the motion trajectory attribute of the object, it can only be determined whether the current environmental condition satisfies the predetermined characteristic, and cannot predict whether the future environmental condition still satisfies the predetermined characteristic, for example, using a sensing device, it cannot distinguish a garbage bag flying ahead from a running child.

Based on this, it is preferable that, in order to improve the safety, regardless of the sensed object, if its moving speed with respect to the target object is fast, even if it is far from the target object, the arrangement or the change of the navigation strategy of the electronic navigation software provided by the foregoing embodiment may be performed.

It should be noted that the fast moving speed of the sensed object and the object relative to the target object includes, but is not limited to, the following situations: (1) the sensed object is in front, the target object is behind, and the sensed object moves in the direction away from the target object, but the moving speed of the target object is far faster than that of the sensed object; (2) the sensed object is in front of the target object, the target object is behind the target object, and the sensed object moves towards the target object, wherein the moving speed of the target object is high, the moving speed of the sensed object is high, or the moving speeds of the sensed object and the sensed object are both general but the relative speed is high.

With the embodiments of the present disclosure, different detection means, such as using a camera or a sensing device, may be used to predict or determine whether the current environmental conditions meet predetermined characteristics.

As an alternative embodiment, the visual cue comprises one or more of the following: performing color-changing display on partial elements or all elements in the navigation interface, wherein the partial elements can be navigation marks in the navigation interface, and can be displayed in red or other special colors to indicate emergency when being displayed visually; changing the display form of the navigation identifier in the navigation interface, for example, when the navigation plan is changed, displaying the navigation identifier in an enlarged manner, and the like; and displaying an alarm identifier around the navigation identifier in the navigation interface, for example, adding an identifier for forbidding driving and the like on the basis of the original navigation identifier when the navigation identifier is paused.

In addition, in order to enrich the types of prompts, voice prompts with preset times can be added on the basis of visual prompts. Of course, these visual prompts, as well as the visual prompts accompanied by voice prompts, may also be performed in advance of a predetermined time, so as to reserve sufficient time for the user to turn, merge, and the like.

By means of the navigation planning method and device, when navigation changes compared with a navigation plan determined in advance, or even if the navigation does not change, a driver or a user needs to be reminded, the driver or the user can be noticed through visual and auditory prompts.
