In addition to the main function of the component, each component to be described below can also perform some or all of the functions of other components, and some of the main functions of each component can be exclusively performed by other components.

[0046] In response to the problems and defects in the related technologies, the present application provides a method for planning charging points before traveling. The method reasonably plans the charging points on the planned route before traveling, effectively improving the rationality of selecting charging stations along the way.

[0047] Before the user has a travel need, the travel parameters can be set through the setting interface provided by the car computer or mobile phone. The travel parameters include one or more of travel time, travel destination, travel priority mode, and destination energy replenishment. After setting the travel parameters on the car computer or mobile phone, the travel parameters need to be synchronized between the car computer and the mobile phone. For example: After setting the travel schedule on the mobile phone APP, the setting information needs to be sent to the car computer through Tbox or the Internet. Similarly, after the car computer is set, the setting information also needs to be synchronized to the mobile phone APP.

[0048] According to the travel parameters set by the user, before the user travels, travel planning and reminders are provided to the user based on the status of the vehicle, and the reminders are sent through messages via a mobile phone APP.

[0049] Before the vehicle is powered off, the GPS module on the vehicle needs to obtain the vehicle's GPS information and upload it to the mobile phone APP. After obtaining the vehicle's location information, the mobile phone APP needs to calculate the travel route from the vehicle's parking location to the destination within a period before the planned trip, as well as recommend refueling points, and then remind users to travel and make preparations before traveling based on the vehicle's status.

[0050] If the user has travel plans for the next day, a reminder will be sent the day before. For example, if the user has travel plans on October 30, 2024, the APP will send a reminder message at 19:00 on October 29, 2024.

[0051] If the mode selected by the user is Economy Priority, when the prompt message is issued, if it is detected that the remaining power of the power battery cannot meet tomorrow's trip, and the SOC() value is lower than 80%, it is recommended that the user complete charging before departure, and the recommended charging time period for the user is:

[0052] time Energy replenishment price Recommended value 0:00～8:00 lowest Highly recommended 8:00～11:00 Low recommend 17:00～20:00 Low recommend 22:00～23:59 Low recommend

[0053] The basis for the recommended time for energy replenishment comes from the current range of electricity prices, and the above time periods are the time periods with lower electricity prices.

[0054] If the user selects the time priority mode, the power and range during the journey need to be considered.

[0055] If the pure electric range can meet the mileage of the next day, no reminder will be given;

[0056] When the pure electric range cannot meet the mileage for the next day and the remaining power of the power battery is less than 70%, the user needs to be reminded to complete charging before departure to ensure the power of the vehicle during the journey;

[0057] When the remaining power of the power battery is higher than 70%, the remaining fuel is lower than 50%, and the pure electric range + fuel range cannot meet the mileage of the next day, you need to be reminded to complete refueling before departure to ensure the range;

[0058] When the remaining power of the power battery is higher than 70%, the remaining fuel level is higher than 50%, and the pure electric range + fuel range cannot meet the mileage of the next day, no prompt is required.

[0059] See also Figure 1 , Figure 1 This is a flow chart of a range-extended vehicle energy replenishment planning method according to an embodiment of the present application. Figure 1 As shown, the range-extended vehicle energy replenishment planning method at least includes steps S110 to S140:

[0060] Step S110, obtaining the starting point and the end point of the trip, and the planned travel path from the starting point to the end point;

[0061] Specifically, the starting point and the end point of the trip can be set on the vehicle terminal or the mobile phone APP. The starting point of the trip indicates the location where the planned travel path starts, and the end point indicates the location where the planned travel path ends.

[0062] Multiple candidate travel planning paths can be obtained based on the travel starting point and the end point. As an example, the final path can be selected from multiple candidate travel planning paths as the travel planning path based on travel needs. Among them, travel needs include but are not limited to highway priority, distance priority, main road priority, low tolls, not taking the highway, avoiding congestion, etc. The planned paths corresponding to different travel needs may be different, may be partially the same, or may be completely different, which is not limited here.

[0063] Step S210, determining multiple energy recharging points on the travel planning route;

[0064] Generally speaking, there are multiple recharging points on a planned travel route. Recharging sites may include gas stations and / or charging stations. The recharging sites included in different planned travel routes may be partially the same or completely different, which is not limited here.

[0065] Step S130, obtaining the vehicle's cruising range influencing factors, and determining the remaining cruising range based on the cruising range influencing factors;

[0066] The factors affecting the remaining cruising range refer to factors affecting the remaining cruising range, which may be a single factor or multiple different factors. As an example, the factors affecting the remaining cruising range include at least one of the following: vehicle status data, road data, vehicle environment data, and driving habits.

[0067] The vehicle's status data includes at least remaining power data, energy consumption data, load status data, etc. The load status data includes either full load status data or underload status data; the road data includes at least road grade data and congestion status data of the vehicle's travel planning route; the vehicle's environmental data includes at least weather data; driving habits include: aggressive driving, stable driving or conservative driving habits.

[0068] As an example, a mapping relationship between the range influencing factors and the remaining range can be established in advance, and then after the range influencing factors are obtained, the corresponding remaining range is determined based on the pre-established mapping relationship. For example, the range influencing factors are used as input and the remaining range is used as output to train the initial neural network model to obtain a range prediction model. After the range influencing factors are obtained, the range influencing factors are input into the range prediction model to obtain the remaining range.

[0069] Step S140, based on the travel mode and the remaining cruising range, a recommended refueling point is determined; the recommended refueling point is one or more of the multiple refueling points.

[0070] In one embodiment, the travel mode includes time priority and economy priority. Time priority means ensuring that the shortest time is required to reach the destination from the starting point; economy priority means consuming the least resources from the starting point to the destination. Different travel modes correspond to different recommended refueling points.

[0071] Taking extended-range electric vehicles as an example, extended-range electric vehicles have both charging and refueling features. Users can choose to recharge at gas stations or charging stations along the way. Therefore, users can decide whether to recharge at gas stations or charging stations based on their chosen travel mode.

[0072] For example, if the travel mode is economic priority, the vehicle can be recharged at a charging station during driving. If the travel mode is time priority, the vehicle is controlled to travel along the planned travel route in fuel priority mode.

[0073] When determining the recommended charging point, the recommended charging point is determined based on the remaining cruising range. The remaining cruising range here refers to the cruising range corresponding to the remaining battery power. Figure 2 , Figure 2 This is a flow chart of determining a recommended refueling point based on the remaining cruising range according to an embodiment of the application. In the case where the travel mode includes economic priority. Determining the recommended refueling point based on the remaining cruising range includes:

[0074] Step S210, determining a vehicle stop position according to the remaining cruising range, where the vehicle stop position represents a position corresponding to the maximum distance that the vehicle can travel based on the remaining cruising range;

[0075] Step S220: taking the previous charging point of the driving section where the vehicle stops as a recommended charging point, so that the vehicle can be charged when it reaches the recommended charging point, wherein a driving section is formed between two adjacent charging points.

[0076] See also Figure 3 , Figure 3 This is a schematic diagram of a travel planning route according to an embodiment of the present application. Figure 3 In the figure, point A is both the starting point of the planned travel route and the charging point, point D is both the end point of the planned travel route and the charging point, and points B and C are the charging points. Point A and point B form the first driving section, point B and point C form the second driving section, and point C and point D form the third driving section.

[0077] If the remaining cruising range is greater than the distance of the first driving section AB, for example, according to the remaining cruising range, the vehicle can travel as far as point E, then point E is the vehicle's stop position. Since the vehicle cannot travel to the recharging point C for recharging, it can only recharge at the recharging point B, and the recharging point B is the recommended recharging point. That is, the previous recharging point B of the driving section BC where the vehicle's stop position E is located is used as the recommended recharging point.

[0078] At charging point A, the remaining range corresponding to the remaining power of the power battery is calculated to be able to reach charging point B, but cannot reach charging point C, then charging point B is used as the recommended charging point. After charging at charging point B is completed, the remaining range corresponding to the remaining power of the power battery is calculated to reach charging point C but cannot reach destination D, then charging point C is used as the recommended charging point, and so on. Each time charging is performed, the next charging point is planned based on the remaining power until destination D.

[0079] In one embodiment of the present application, the energy replenishment planning method also includes: in the case where the vehicle fails to recharge at the previous recharging point of the driving section where the vehicle stops, taking the next recharging point of the driving section where the vehicle stops as a new recommended recharging point; determining the power generation amount according to the distance between the vehicle stop position and the new recommended recharging point; and starting the on-board generator to generate power based on the power generation amount when the vehicle meets the power generation conditions, so as to control the vehicle to travel to the new recommended recharging point for recharging.

[0080] Continue as Figure 3 As shown, during the journey, if it is found that it is possible to reach the charging point B but cannot reach the charging point C for charging, then the charging point B needs to be used as the charging point for charging. If in this state, the user does not charge when passing point B, the power gap required from charging point B to charging point C is calculated, and then the generator is started to generate power at high speed. After the generator completes the power generation of the gap, the engine is stopped to generate power. When the charging point C is reached for charging, the normal journey continues.

[0081] Specifically, if the vehicle does not recharge at the recharging point B, that is, it does not recharge at the previous recharging point B of the driving section BC where the vehicle stop position E is located, the vehicle can only travel to point E. Therefore, in the subsequent driving process, the recharging point C is used as the new recharging point, that is, the next recharging point C of the driving section BC where the vehicle stop position E is located is used as the new recommended recharging point. Since the vehicle can only travel to the vehicle stop position E based on the power, the on-board generator will generate electricity at the vehicle stop position E to drive the vehicle to the recharging point C. The power generation of the on-board generator is determined according to the distance between the vehicle stop position E and the new recharging point C, and the power generation is sufficient as long as it can meet the requirements of reaching the new recharging point C from the vehicle stop position E. Among them, the on-board generator is started when the vehicle's driving speed reaches the speed threshold. The speed threshold can be set to a speed value between 70km / h and 80km / h. For example, the generator can be started to generate electricity when the driving speed exceeds 70km / h.

[0082] In one embodiment of the present application, the energy replenishment planning method also includes: when the remaining cruising range is greater than the sum of the distances of adjacent driving sections, determining the time sequence of the vehicle reaching the next energy replenishment point of the adjacent driving sections; and determining the recommended energy replenishment point based on the amount of resources consumed for energy replenishment at each time point in the time sequence.

[0083] As an example, the adjacent driving sections may be the first driving section AB and the second driving section BC. When the remaining cruising range is greater than the sum of the distances of the adjacent driving sections, that is, the remaining cruising range is the sum of the distances of the first driving section AB and the second driving section BC, the vehicle can pass through the recharging point B and the recharging point C based on the remaining cruising range. At this time, the first time point of passing through the recharging point B and the second time point of passing through the recharging point C are obtained, and then a time series is formed. For example, the time to arrive at the recharging point B is 7:00am, and the time to arrive at the recharging point C is 10:00am. According to the pre-setting, the resources consumed for recharging in the time period of 0:00-8:00 are the least, so the recharging point B is selected as the recommended recharging point. Among them, low resource consumption can be understood as low cost for recharging.

[0084] As an example, judging the time to reach the charging point, recommending charging. If the remaining power of the power battery can reach charging point C when reaching charging point B, but the time to reach charging point B is more than 30 minutes away from the next high electricity price period, and the time to reach charging point C is about to reach the next high electricity price period or is already in the high electricity price period, it is recommended to complete charging at charging point B as the recommended charging point. If the arrival time of charging point B and charging point C are both in the high electricity price period, the above rules are still followed, and charging is completed at charging point C, the farthest location that can be reached by pure electric range, and charging point C is set as the recommended charging point.

[0085] Assume that charging point C is close to destination D, but the electricity price is high during the charging period, so less energy can be charged to meet the journey from charging point C to destination D.

[0086] In one embodiment of the present application, when the travel mode includes time priority, the vehicle is controlled to travel along the planned travel path in a fuel priority mode.

[0087] Specifically, when the travel mode is time-prioritized, if the user chooses refueling as the refueling method at the destination, the fuel priority mode is used to complete the entire journey from the starting location to the end location; if the user chooses charging as the refueling method at the destination, the fuel priority mode is used from the starting point to the set location. When the remaining power of the power battery can meet the journey from the set location to the destination, the pure electric priority mode is used to complete the journey from the set location to the destination when at the set location.

[0088] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
