Description

Technical Field

[0001] The present invention relates to the field of signal processing technology, and in particular to a decision-making method, device, system and component for finding an energy replenishment site. Background Art

[0002] Currently, when an autonomous vehicle runs out of energy and needs to recharge while driving, it usually searches for nearby gas stations or charging stations based on a real-time map. The vehicle then decides which recharging station to go to based on its own location, direction, and current energy status. The decision is usually based on time priority or distance priority.

[0003] When deciding where to refuel, autonomous vehicles only consider their own status and the locations and types of refueling stations identified on the map. They lack access to the real-time operational status of refueling stations. After selecting a refueling station based on their preferences and arriving, autonomous vehicles often face long queues or unavailable refueling stations due to maintenance. In these situations, autonomous vehicles may need to replan their route and search for other refueling stations, or they may run out of energy to reach the newly planned refueling station, forcing them to wait in line for a long time. Therefore, finding optimal refueling stations and improving refueling efficiency for autonomous vehicles has become an urgent problem that needs to be solved. Summary of the Invention

[0113] Example 1

[0114] Embodiment 1 of the present invention provides a decision-making method for finding a charging station, and the execution subject of this application is a vehicle-side control center. Figure 1 This is a schematic diagram of a decision method for finding a recharging site provided in the first embodiment of the present invention, such as Figure 1 As shown, this decision-making method mainly includes the following steps:

[0115] Step 110 , sending a list of energy replenishment information generated based on the real-time vehicle-side data to a cloud server, wherein the list of energy replenishment information includes the vehicle-side ID, energy type, real-time remaining planned route information, and remaining mileage data.

[0116] Among them, the energy type can be any energy available to the vehicle, which can be a single energy or a mixed energy; single energy includes fuel energy, electric energy, hydrogen energy, etc.; mixed energy can include any combination of at least two single energy sources, such as a mixed energy of fuel and electricity, or a mixed energy of fuel and hydrogen, or a mixed energy of fuel, electricity and hydrogen.

[0117] Among them, the planned path information is the path information planned by the vehicle from the starting point to the end point, and the real-time remaining planned path information is the remaining planned path information from the real-time position of the vehicle to the end point during the driving process.

[0118] Among them, the remaining mileage data is the mileage data that the vehicle can still travel when the energy is exhausted, which is calculated based on the remaining energy on the vehicle side.

[0119] Step 120: Obtain the to-be-selected energy replenishment site information pushed by the cloud according to the energy replenishment information list, wherein the to-be-selected energy replenishment site information includes the site ID, location information, energy replenishment type, site rating information, site vacancy rate, and surrounding service facility information of the to-be-selected energy replenishment site.

[0120] Specifically, there are one or more recharging sites to be selected, wherein the recharging types of the recharging sites to be selected include single energy recharging sites or mixed energy recharging sites; the site rating information is the rating submitted by historical vehicle-side users for various services of the site after completing recharging at the site; the site vacancy rate is calculated and generated by the site based on the real-time recharging vehicle situation and the scheduled recharging vehicle situation at the site; the surrounding service facility information includes service facilities within a preset distance range, such as toilets, convenience stores and maintenance stations, as well as the coordinate information of the service facilities on the driving map.

[0121] In a possible implementation, if the energy replenishment type is electric energy, the information of the site to be replenished further includes information on the type of charging pile of the site to be selected.

[0122] Among them, the types of charging piles include DC charging piles, AC charging piles, and AC / DC integrated charging piles. DC charging piles can charge quickly but have an impact on the life of the rechargeable battery. AC charging piles have a small charging current and a long charging time, which have little impact on the battery life. When time is limited, the vehicle side can give priority to DC charging piles to improve energy replenishment efficiency. If time is sufficient, AC charging piles can be selected to protect the battery life.

[0123] Step 130: Calculate and generate the energy replenishment positive effect index of the candidate energy replenishment site based on the candidate energy replenishment site information.

[0124] Specifically, the higher the positive effect index of the energy replenishment site to be selected, the greater the benefit can be obtained by replenishing energy at the energy replenishment site, and it is the best choice.

[0125] In one possible implementation, step 130 specifically includes steps A1 to A3:

[0126] Step A1: Calculate and generate a first index component of the energy replenishment positive effect index based on the real-time location information of the vehicle, the location information of the energy replenishment site, and the real-time remaining planned path information.

[0127] Specifically, a to-be-selected recharging route is planned with the real-time location of the vehicle as the starting point and the location of the recharging station as the end point; a path overlap end point is found based on the to-be-selected recharging route and the real-time remaining planned path information; a first distance from the path overlap end point to the to-be-selected recharging station location and a second distance from the vehicle end from the to-be-selected recharging station location back to the path point of the real-time remaining planned path are summed to generate a third distance; a fourth distance between the path overlap end point and the path point of the real-time remaining planned path is calculated; a ratio or difference is calculated between the third distance and the fourth distance, and the ratio or difference is negatively correlated with the first exponential component.

[0128] In a specific example, assume that the first 20 kilometers of the planned alternative recharging route from the vehicle's real-time location to the recharging station overlap. At 20 kilometers, the routes diverge, and the path point at this point is recorded as the path overlap endpoint. The first distance from the path overlap endpoint to the alternative recharging station is 1 kilometer. The second distance from the vehicle's location to the path point on the real-time remaining planned path is 1.5 kilometers. The sum of the first and second distances is a third distance, which is 2.5 kilometers. The fourth distance between the path overlap endpoint and the path point on the real-time remaining planned path is 0.5 kilometers. The ratio of the third distance to the fourth distance is 5, or the difference is 2 kilometers. The size of the ratio or difference between the third and fourth distances represents the additional mileage consumed by the vehicle to reach the alternative recharging station relative to the original planned route, with larger values ​​indicating a disadvantage.

[0129] Step A2: generating a second index component of the energy replenishment positive effect index according to the site vacancy rate.

[0130] Specifically, the station vacancy rate is calculated by the station based on the real-time and scheduled vehicle availability at the station. The station vacancy rate is positively correlated with the magnitude of the second exponential component. A higher station vacancy rate indicates fewer vehicles are recharging, resulting in less queuing at the recharging station and reduced recharging time.

[0131] Step A3: Calculate and generate a third index component of the energy replenishment positive effect index based on the energy replenishment site location information and the real-time remaining planned path information.

[0132] Specifically, the distance from the location of the charging station along the real-time remaining planned path to the end point of the real-time remaining planned path is calculated; if the distance is not greater than the vehicle-side cruising range, the third exponent component is greater than zero; if the distance is greater than the vehicle-side cruising range, the third exponent component is equal to zero.

[0133] When the distance from the location of the charging station along the real-time remaining planned path to the end point of the real-time remaining planned path is less than the vehicle's endurance range, it indicates that the vehicle no longer needs to recharge after reaching the final destination after the charging is completed; when the distance from the location of the charging station along the real-time remaining planned path to the end point of the real-time remaining planned path is greater than the vehicle's endurance range, it indicates that the vehicle still needs to recharge before reaching the final destination after the current charging is completed, and the selection of a candidate charging station that no longer needs to recharge is better than the selection of a candidate charging station that needs to be recharged again.

[0134] In another possible implementation, step 130, after step A3, further includes:

[0135] Step A4, calculating and generating a fourth index component of the positive effect index of the recharging according to the real-time position information of the vehicle, the remaining drivable mileage data, the position information of the recharging station and the real-time remaining planned path information.

[0136] Specifically, the second duration required to travel from the location of the recharging station along the real-time remaining planned path to the end point of the real-time remaining planned path is calculated; the third duration required to travel from the real-time location of the vehicle to the location of the recharging station is calculated; the fourth duration, which is the minimum time required for recharging on the vehicle side, is calculated based on the second duration, the third duration and the remaining drivable mileage data; if the autonomous driving vehicle has a time limit for traveling to the final destination, during the recharging process, the minimum amount of energy that needs to be replenished can be calculated based on the real-time remaining planned path plus a preset safety threshold for recharging, thereby saving the total vehicle-side driving time.

[0137] If the second duration is greater than the vehicle's endurance, the fourth exponential component is equal to zero; at this time, after the vehicle has replenished enough energy, it still needs to replenish energy before reaching the destination, which consumes a long total driving time.

[0138] If the second duration is no greater than the vehicle's endurance, the total of the second, third, and fourth durations is calculated. This total duration is negatively correlated with the magnitude of the fourth exponential component. If the second duration is no greater than the vehicle's endurance, this indicates that when recharging at the candidate recharging station, only a portion of the energy can be replenished based on the real-time remaining planned route distance, thus saving total driving time. The shorter the total duration, the more favorable the selection of the candidate recharging station.

[0139] Step 140 : If the difference between the maximum positive energy replenishment effect index and the other positive energy replenishment effect indexes is greater than a preset deviation threshold, the candidate energy replenishment site with the maximum positive energy replenishment effect index is selected as the target energy replenishment site.

[0140] Specifically, a positive energy replenishment effect index is calculated for each candidate energy replenishment site, and the sites are sorted according to their numerical values. The larger the positive energy replenishment effect index is, the more favorable it is to select the candidate energy replenishment site as the target energy replenishment site.

[0141] Step 150 : If the difference between the maximum energy replenishment positive effect index and the other energy replenishment positive effect indexes is not greater than a preset deviation threshold, a target energy replenishment site is selected according to a preset priority list.

[0142] If the difference between the maximum positive energy replenishment effect index and one or more other positive energy replenishment effect indices is no greater than a preset deviation threshold, it indicates that the benefit of selecting the candidate energy replenishment site with the maximum positive energy replenishment effect index as the target energy replenishment site is not significantly different from selecting the candidate energy replenishment site with the other one or more positive energy replenishment effect indices as the target energy replenishment site. The target energy replenishment site can be further optimized using a preset priority list.

[0143] In one possible implementation, if the energy replenishment type is electric energy, the items in the preset priority list include DC, AC, and AC / DC. In a specific example, the priority of the preset priority list is DC first, then AC / DC, and finally AC.

[0144] In one possible scenario, Figure 2 This is a second schematic diagram of a decision-making method for finding an energy replenishment site provided in the first embodiment of the present invention, as shown in FIG. Figure 2 As shown, before step 150, the decision-making method further includes:

[0145] Step 210 : updating the preset priority list according to the additional service request information, wherein the additional service request information includes the need to configure toilets, and / or convenience stores, and / or maintenance stations around the charging station.

[0146] While the vehicle is driving, temporary additional service needs may arise. When these needs arise, an additional service request is generated, and the preset priority list is updated based on the additional service request. In a specific example, the additional service request indicates the need for restrooms near the recharging station. If the preset priority list before the update prioritizes DC, then AC / DC hybrid, and finally AC, the updated preset priority list prioritizes restrooms, then DC, then AC / DC hybrid, and finally AC. Real-time updates to the preset priority list further optimize target recharging stations.

[0147] In another possible solution, if the energy replenishment type is electric energy, Figure 3 This is a third schematic diagram of a decision-making method for finding an energy replenishment site provided in the first embodiment of the present invention, as shown in FIG. Figure 3 As shown, after step 150, the decision-making method further includes:

[0148] Step 310: Send the site ID of the selected target charging site to the cloud server.

[0149] Step 320: Obtain the charging pile information reserved by the cloud server through the site ID of the target charging site.

[0150] After the vehicle side selects the site ID of the target charging station, the cloud server sends a charging pile reservation application to the field side corresponding to the site ID according to the site ID of the target charging station. The reservation application includes the vehicle side ID of the reserved vehicle side. The field side binds the vehicle side ID and the idle charging pile. After binding, other vehicles are unavailable. When the vehicle side arrives at the target charging station and establishes communication with the field side, the bound charging pile is released to the vehicle side. In one possible implementation, the reserved charging pile information includes the pile position locking time. The pile position locking time of the target charging station can be set according to the vacancy rate of the station. The vacancy rate is positively correlated with the pile position locking time. By setting the pile position locking time, it can be avoided that the vehicle side cannot reach the charging pile in time due to external factors and overtime occupancy affects the operating efficiency of the target charging station.

[0151] In another possible solution, Figure 4 This is a fourth schematic diagram of a decision-making method for finding an energy replenishment site provided in the first embodiment of the present invention, as shown in FIG. Figure 4 As shown, after step 320, the decision-making method further includes:

[0152] Step 410 : planning a target charging path according to the location information of the target charging site, with the end point of the target charging path being the predetermined location of the target charging site.

[0153] Step 420: After driving to the predetermined location of the target charging station according to the planned target charging route, send arrival confirmation information to the station end.

[0154] Step 430: Establish a communication connection with the field end and receive a field end control request.

[0155] Step 440: Drive to the reserved charging station according to the dispatch control instruction of the field end.

[0156] Specifically, when the vehicle arrives at the target charging station and receives the control request from the field, the vehicle performs a communication handshake and releases control to the field. The field obtains the location of the charging pile based on the charging pile ID bound to the vehicle, and generates a scheduling control instruction based on the location of the charging pile. In one possible implementation, the scheduling control instruction includes steering wheel control instructions, vehicle speed, throttle, brake, gear and other instructions.

[0157] In another possible solution, Figure 5 This is a fifth schematic diagram of a decision-making method for finding an energy replenishment site provided in the first embodiment of the present invention, as shown in FIG. Figure 5 As shown, before step 420, the decision-making method further includes:

[0158] Step 510: Obtain a first time duration to reach the target energy replenishment site in real time.

[0159] Step 520: If it is determined based on the first time period that the target charging site cannot be reached within the pile position locking time period, the process returns to step 110.

[0160] Specifically, when the vehicle takes too long to reach the target charging station within the charging station lock time due to environmental factors, the vehicle will search for the charging station again based on the real-time data of the vehicle to avoid the situation where the target charging station has unbound the bound charging pile, resulting in failure to recharge in time and need to queue for recharging.

A first distance from the path overlapped with the end point to the to-be-selected recharging station location and a second distance from the vehicle's location from the to-be-selected recharging station back to the path point of the real-time remaining planned path are summed to generate a third distance.

A ratio or difference is calculated between the third distance and the fourth distance, where the ratio or difference is negatively correlated with the first exponential component.

[0172] Furthermore, the third index component of the energy replenishment positive effect index is calculated based on the energy replenishment site location information and the real-time remaining planned path information, specifically:

[0174] If the distance is not greater than the vehicle's endurance range, the third index component is greater than zero;

[0175] If the distance is greater than the vehicle's endurance range, the third exponent component is equal to zero.

[0180] Calculate the second duration required to travel from the location of the charging station along the real-time remaining planned path to the end point of the real-time remaining planned path; calculate the third duration required from the real-time location of the vehicle to the location of the charging station; calculate the fourth duration, which is the minimum duration required for charging on the vehicle side, based on the second duration, the third duration and the remaining drivable mileage data; if the second duration is greater than the vehicle side's endurance time, the fourth index component is equal to zero; if the second duration is not greater than the vehicle side's endurance time, calculate the total duration of the second, third and fourth durations, and the total duration is negatively correlated with the size of the fourth index component.
