While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.

Fig. 1 shows a flowchart of a navigation path planning method according to a first embodiment of the present invention, which is executed by a navigation path planning device and an energy consumption model server. As shown in fig. 1, the method comprises the steps of:

step 101, when a navigation request is received, navigation equipment acquires navigation path planning related data information and residual electric quantity information; the navigation path planning related data information carries destination information;

the navigation device can be a mobile terminal (for example, a smart phone with a navigation APP) or a vehicle-mounted navigation device, and the input mode can be screen input method input or voice input or direct click to select a navigation destination.

wherein, the data information related to the navigation path planning comprises: navigation destination information, congestion state, traffic flow condition, and mileage navigated to the destination; and the residual capacity information of the vehicle is measured by the vehicle.

Step 1031, the navigation equipment receives a first path plan sent by the energy consumption model server;

According to the embodiment of the invention, the energy supplementing factor is planned in the navigation path, so that the first path plan including the energy supplementing priority can be provided when the remaining driving mileage of the vehicle is less than the mileage navigated to the destination, and the user can select the first path plan preferentially. Specifically, the navigation path planning related data information and the residual electric quantity information are transmitted to the energy consumption model server through the navigation equipment, and the energy consumption model server can calculate the energy consumption under the current driving working condition based on the driving habit data of the user, so that the residual endurance mileage corresponding to the current residual electric quantity is calculated. And providing a first path plan containing energy supplement priority on the basis of the condition that the remaining driving mileage corresponding to the current remaining power information is less than the mileage navigated to the destination, so that the problem that the vehicle cannot reach the destination due to insufficient remaining power is solved. In addition, the energy consumption model server side can calculate the remaining endurance mileage corresponding to the remaining electric quantity through the current driving working condition of the user, so that the user can have visual perception on the endurance mileage on the remaining electric quantity, and meanwhile, the problems of energy compensation worry and mileage anxiety of the pure electric vehicle user are solved.

Fig. 2 shows a flowchart of a second embodiment of the navigation path planning method of the present invention, which is executed by a navigation path planning apparatus. As shown in fig. 2, the method comprises the steps of:

step 101, when a navigation request is received, navigation equipment acquires navigation path planning related data information and residual electric quantity information; the navigation path planning related data information carries destination information;

the navigation device can be a mobile terminal (for example, a smart phone with a navigation APP) or a vehicle-mounted navigation device, and the input mode can be screen input method input or voice input or direct click to select a navigation destination.

102, the navigation equipment sends the navigation path planning related data information and the residual electric quantity information to an energy consumption model server;

wherein, the data information related to the navigation path planning comprises: navigation destination information, congestion state, traffic flow condition, and mileage navigated to the destination; and the residual capacity information of the vehicle is measured by the vehicle.

Step 1031, the navigation equipment receives a first path plan sent by the energy consumption model server;

the first path plan is generated by the energy consumption model server according to the navigation path plan related data information and the energy supplementing point information when the remaining endurance mileage corresponding to the remaining electric quantity information is less than the mileage navigated to the destination, and the first path plan includes: the energy supplement is prior, the time is shortest, the distance is shortest, and the high speed is prior.

And the energy consumption model server calculates the energy consumption of the vehicle under the current driving working condition according to the driving habit data of the user, so that the remaining endurance mileage corresponding to the current remaining electric quantity is calculated. When the remaining endurance mileage is less than the mileage navigated to the destination, automatically adding energy supplementing factors in the path plan generated by the energy consumption model server side, and giving a first path plan including energy supplementing priority;

step 1032, the navigation equipment displays the first path plan from the energy consumption model server for the user to select;

the energy compensation is preferentially used as a path plan obtained after the energy compensation factor is increased, and the path plan is placed at the first position of the first path plan so as to facilitate and guide the user to preferentially select;

step 1034, if the navigation equipment does not receive the instruction of energy supplement priority, the navigation equipment receives a second path plan from the energy consumption model server;

the second path plan is generated by the energy consumption model server side according to the navigation path plan related data information and the energy supplementing point information when the remaining endurance mileage corresponding to the remaining electric quantity information is smaller than a preset threshold value, and is used for indicating the navigation equipment to navigate to the energy supplementing point; the preset threshold is smaller than the navigation mileage to the destination;

the preset distance threshold value can be set and recorded at the energy consumption model server side, and at least the following three setting modes are provided for the distance threshold value: 1. the official preset value is set to a fixed value, for example 60km, according to the model of the vehicle. 2. The user-specific distance threshold may be set by the user, but the user-set distance threshold is greater than or equal to an official preset value, for example, 60km, and the user may set the distance threshold to 80km by the user. 3. The energy consumption model server dynamically calculates according to the driving habits of the users, and can adjust according to a certain period, such as monthly.

Step 1035, the navigation device executes the second path plan, navigating to the energy complementing point.

In the second embodiment of the present invention, on the basis of the first embodiment, when the navigation device does not receive the instruction of priority energy replenishment and the remaining driving range corresponding to the remaining power information is smaller than the preset threshold, the navigation device receives the second path plan from the energy consumption model server. When the remaining endurance mileage corresponding to the remaining power information is smaller than the preset threshold, the remaining power cannot meet the endurance requirement of the user for navigating to the destination, and even the user can run out of the remaining power on the way to the destination and cannot reach the energy supply station. Therefore, under the condition, the navigation device receives the second path plan from the energy consumption model server and instructs the navigation equipment to navigate to the energy supplementing point for energy supplementing, so that the situation that the user selects other navigation paths by mistake or the residual energy is not supplemented in time after the residual energy is estimated by mistake to cause residual energy exhaustion is avoided, and the user experience is improved.

It should be noted that the second path plan includes: if the route planning to the energy supplement point with short energy supplement time is navigated, then the specific execution of step 1035 includes: and the navigation equipment executes the route planning of navigating to the energy supplementing point with short energy supplementing time consumption and navigates to the energy supplementing point. Since the user is given a route plan that consumes a short amount of energy in the energy replenishment time in the second route plan, the anxiety of the user in the energy replenishment can be eliminated in the dimension of saving time.

Wherein, the energy supplementing time consumption comprises: the time of driving to the target energy supplementing point, the waiting time of the target energy supplementing point and the time of supplementing energy to the preset electric quantity. And when the waiting time of the target energy supplementing point is specifically determined, the energy consumption model server side is determined according to a first rule. The first rule may specifically be: if the residual charging time of the current vehicle at the target energy supplementing point is greater than the time of driving to the target energy supplementing point, taking the difference value between the residual charging time of the current vehicle at the target energy supplementing point and the time of driving to the target energy supplementing point as the waiting time of the target energy supplementing point, and if the residual charging time of the current vehicle at the target energy supplementing point is less than or equal to the time of driving to the target energy supplementing point, determining that the waiting time of the target energy supplementing point is zero; and the current vehicle residual charging time of the target energy supplementing point is determined according to the time for supplementing energy to a preset electric quantity.

For example, if the time when the vehicle travels to the energy charging point is denoted as t1, and the current vehicle remaining charging time at the energy charging point is denoted as t2, the energy charging point at which t2 is close to t1 is preferably selected. If the residual electric quantity is not enough to reach a certain energy supplementing point nearby, the energy supplementing point displays a prompt for exceeding the residual electric quantity range; and the energy supplementing point within the range of the residual electric quantity can be used.

More specifically, the second path planning may further include: and navigating to the path planning of a plurality of energy supplementing points with short energy supplementing time. Thus, when step 1035 is executed, the method includes: the navigation equipment displays the route planning of navigating to a plurality of energy supplementing points with short energy supplementing time consumption; and navigating to the energy supplementing point selected by the user according to the selection of the user. Therefore, the path planning of a plurality of energy supplementing points which are short in energy supplementing time consumption is given to the user for reference in the second path planning, and the negative impression of forced execution on the psychology of the user is avoided. In addition, the user can also adjust the target energy supplementing point within the range allowed by the residual electric quantity so as to meet the additional requirements of the user in the vehicle energy supplementing process, such as eating, shopping, fetching, receiving people and the like.
