Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. 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 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; the navigation path planning related data information carries destination information;
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 of the vehicle is measured by the vehicle.
Step 1031, the navigation equipment receives the path plan sent by the energy consumption model server;
the energy consumption model server calculates the energy consumption under the current driving working condition according to the driving habit data of the user, so that the endurance mileage of the current residual electric quantity is calculated. When the remaining electric quantity is less than the mileage navigated to the destination, automatically increasing an energy supplementing factor in a path plan generated by the energy consumption model server, and indicating the navigation equipment to navigate to an energy supplementing point;
step 1032, the navigation equipment displays the path plan sent by the energy consumption model server;
the energy supplement is preferentially taken as a path plan obtained after an energy supplement factor is added, and the path plan is generated according to navigation path plan related data information and energy supplement point information when the remaining endurance mileage corresponding to the remaining electric quantity information is less than the mileage navigated to the destination by the energy consumption model server side and indicates the navigation equipment to navigate to an energy supplement point;
and 1033, the navigation equipment navigates to the energy supplementing point according to the path plan.
According to the first embodiment of the invention, by planning the energy supplementing factor into the navigation path, when the remaining driving mileage corresponding to the remaining electric quantity information of the vehicle is less than the mileage navigated to the destination, the path plan containing the energy supplementing point can be provided, and the navigation equipment is instructed to navigate to the energy supplementing point. Specifically, data information related to navigation path planning input by a user and the residual electric quantity information of the vehicle 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 cruising mileage of the current residual electric quantity is calculated. And providing a path plan containing energy supplementing points when the remaining driving range corresponding to the remaining power information of the vehicle is less than the range navigated to the destination, so as to reduce the problem that the destination cannot be reached due to insufficient remaining power. When the remaining endurance mileage corresponding to the remaining power information is less than the mileage navigated to the destination, the remaining power may not only satisfy the endurance requirement of the user navigated to the destination, but also may even cause the problem that the user runs out of remaining power on the way to the destination and cannot reach the energy supply station. Therefore, under the condition, the navigation device navigates to the energy supplementing point according to the path plan to supplement energy, so that the situation that the residual electric quantity is exhausted due to the fact that energy is not supplemented in time is avoided, and the user experience is improved. In addition, the energy consumption model server side can calculate the endurance mileage corresponding to the residual electric quantity through the current driving working condition of the user, so that the user can visually perceive the residual electric quantity on the endurance mileage, and meanwhile, the problems of energy compensation worry and mileage anxiety of the pure electric vehicle user are solved.

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 path plan which is sent by the energy consumption model server and comprises a plurality of energy supplementing points with short energy supplementing time;
the energy consumption model server calculates the energy consumption under the current driving working condition according to the driving habit data of the user, so that the endurance mileage of the current residual electric quantity is calculated. When the remaining electric quantity is less than the mileage navigated to the destination, automatically increasing an energy supplementing factor in a path plan generated by the energy consumption model server, and indicating the navigation equipment to navigate to an energy supplementing point;
it should be noted that, navigating to a path plan of a plurality of energy complementing points with short energy complementing time consumption includes: 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.
Step 1032, the navigation equipment displays a path plan which is sent by the energy consumption model server and comprises a plurality of energy supplementing points with short energy supplementing time;
the energy supplement is preferentially taken as a path plan obtained after an energy supplement factor is added, and the path plan is generated according to navigation path plan related data information and energy supplement point information when the remaining endurance mileage corresponding to the remaining electric quantity information is less than the mileage navigated to the destination by the energy consumption model server side and indicates the navigation equipment to navigate to an energy supplement point;
and 1033, the navigation equipment navigates to the energy supplementing point according to the path plan.
The second embodiment of the invention comprises the path planning of navigating to a plurality of energy supplementing points which consumes short time for energy supplementing on the basis of the first embodiment. Thus, when performing step 1032, it comprises: 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 provided for the user to refer to in the path planning, and the negative impression of forced execution in the user psychology 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.
