Description

Technical Field

[0001] The present invention relates to the field of vehicles, and in particular to a system and method for planning a vehicle charging and driving route. Background Art

[0002] During the driving process, the user estimates the mileage that the vehicle can travel based on the remaining energy of the vehicle, and through the mileage that the vehicle can travel, the user can judge whether the vehicle can reach the destination and whether the vehicle needs to be recharged. Therefore, in the case of subjective misjudgment by the user, the vehicle's remaining energy is low and the vehicle cannot be driven to the energy supply station. Existing vehicles have energy supply systems that can automatically search for the distribution of surrounding energy supply stations, but when the remaining energy of the vehicle is low, there may be a situation where the vehicle cannot drive to the energy supply station. Therefore, there is room for improvement. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a method, device, equipment and medium for planning a vehicle charging route, which is used to solve the problem in the prior art that a vehicle cannot travel to an energy supply station when the remaining energy is low.

[0004] To achieve the above objectives and other related objectives, the present invention provides a vehicle charging route planning system, comprising:

[0005] Energy monitoring module, used to obtain the remaining energy of the vehicle;

[0006] A navigation and positioning module for obtaining vehicle location data; and

[0007] A calculation module is used to calculate the remaining mileage of the vehicle based on the remaining energy of the vehicle, and compare the value between the remaining mileage and a preset first threshold mileage:

[0008] When the remaining mileage is less than the first threshold mileage, in the forward direction of the vehicle, and when the remaining mileage is greater than or equal to the distance between the vehicle and a charging destination, generating a vehicle navigation route based on the location data;

[0009] When the remaining mileage is less than the first threshold mileage, in the vehicle's forward direction, and when the remaining mileage is less than the distance between the vehicle and a charging destination, obtaining charging stations located around the vehicle, and generating a vehicle navigation route based on the location data;

[0010] When the remaining driving mileage is greater than or equal to the first threshold mileage, no vehicle navigation route is generated.

[0011] In one embodiment of the present invention, the vehicle charging route planning system includes a voice broadcast module. When the remaining mileage is less than the first threshold mileage, the calculation module controls the voice broadcast module to generate a vehicle charging voice broadcast. When the remaining mileage is greater than or equal to the first threshold mileage, the calculation module does not generate a vehicle charging voice broadcast.

[0012] In one embodiment of the present invention, the calculation module is used to receive input instructions for charging the vehicle and instructions for not charging the vehicle. When the instruction for charging the vehicle is received, the calculation module obtains the charging destination or the charging station for charging the vehicle, and generates a vehicle navigation route based on the location data. When the instruction for not charging the vehicle is received, the calculation module determines whether to generate a vehicle charging voice broadcast by comparing the remaining mileage with a preset second threshold mileage.

[0013] In one embodiment of the present invention, when the remaining mileage is less than the threshold mileage, and when the vehicle is on a highway, in the forward direction of the vehicle, the calculation module determines whether the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination;

[0014] When the remaining mileage is less than the threshold mileage and the vehicle is not on a highway, the navigation and positioning module obtains charging stations around the vehicle, and the calculation module generates a vehicle navigation route.

[0015] In one embodiment of the present invention, when the vehicle has completed the charging operation, the calculation module again compares the remaining mileage with the preset threshold mileage.

[0016] When the vehicle charging operation is not completed, the calculation module generates a vehicle charging voice broadcast.

[0017] In one embodiment of the present invention, when the vehicle has not completed the charging operation, the calculation module generates a vehicle charging voice announcement and compares the value of the remaining mileage with the value of the distance between the vehicle and the nearest charging station.

[0018] The present invention also proposes a method for planning a vehicle charging route, comprising:

[0019] Obtain the remaining energy of the vehicle to calculate the remaining mileage of the vehicle;

[0020] comparing the remaining mileage with a preset first threshold mileage;

[0021] When the remaining mileage is less than the first threshold mileage, determining whether the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination in the forward direction of the vehicle;

[0022] In the forward direction of the vehicle, when the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination, generating a vehicle navigation route;

[0023] In the forward direction of the vehicle, when the remaining mileage is less than the distance between the vehicle and the charging destination, obtaining charging stations around the vehicle to generate a vehicle navigation route; and

[0024] When the remaining driving mileage is greater than or equal to the first threshold mileage, no vehicle navigation route is generated.

[0025] In one embodiment of the present invention, the step of comparing the remaining mileage with a preset first threshold mileage includes:

[0026] comparing the remaining mileage with a preset first threshold mileage;

[0027] When the remaining mileage is less than the first threshold mileage, generating a vehicle charging voice announcement; and

[0028] When the remaining mileage is greater than or equal to the first threshold mileage, no vehicle charging voice announcement is generated.

[0029] In one embodiment of the present invention, after the step of generating a vehicle charging voice announcement when the remaining mileage is less than the first threshold mileage, the following steps are included:

[0030] receiving an input instruction to charge the vehicle, obtaining the charging destination or the charging station for charging the vehicle, and generating a vehicle navigation route; and

[0031] An input instruction not to charge the vehicle is received, and a numerical value between the remaining mileage and a preset second threshold mileage is compared to determine whether to generate a vehicle charging voice broadcast.

[0032] In one embodiment of the present invention, when the remaining mileage is less than the threshold mileage, the step of determining whether the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination in the forward direction of the vehicle includes:

[0033] When the remaining mileage is less than the threshold mileage, determining whether the vehicle is located on a highway;

[0034] When the vehicle is on a highway, determining whether the remaining mileage is greater than or equal to the distance between the vehicle and a charging destination in the vehicle's forward direction; and

[0035] When the vehicle is not on a highway, the charging stations located around the vehicle are obtained to generate a vehicle navigation route. As described above, the system and method for planning a vehicle charging route of the present invention have the following beneficial effects: the present invention can improve the efficiency of charging when the vehicle is low on energy and increase the fault tolerance of the vehicle in route planning.

[0044] See also Figure 1 As shown, currently vehicles have energy types such as gasoline, diesel, hybrid, pure electric, plug-in hybrid and extended-range. Most of the models on the market currently need to use fossil fuels, that is, gasoline or diesel as fuel for internal combustion engines to drive the vehicle. With the rise in energy prices and the improvement of emission and fuel consumption standards, hybrid, plug-in hybrid, extended-range and pure electric vehicles are becoming more and more common. The present invention provides a vehicle charging driving route planning system, which can plan the vehicle charging driving route, and can be described in detail through the following embodiments.

[0045] See also Figure 1As shown, in some embodiments, in order to plan a vehicle charging route, it is necessary to obtain the vehicle's oil pressure / power data 310 to calculate the vehicle's remaining mileage. It is also necessary to obtain the vehicle's location data 330 to perform navigation and positioning of the vehicle's location. Furthermore, it is necessary to obtain the vehicle's image data 320 to record the vehicle's driving conditions along the route. For example, for a fuel vehicle, the oil pressure / power sensor 210 can be used to monitor the fuel pressure of the fuel vehicle to determine the remaining fuel level. For an electric vehicle, the oil pressure / power sensor 210 can be used to monitor the battery level of the electric vehicle to determine the remaining power level. For a hybrid vehicle, the oil pressure / power sensor 210 can be used to monitor the remaining fuel level and remaining power level of the hybrid vehicle. The present invention provides a vehicle charging route planning system 100, which may include an energy monitoring module 110, an image processing module 120, a navigation and positioning module 130, and a calculation module 140. The energy monitoring module 110 can be electrically connected to the oil pressure / electricity sensor 210, and the energy monitoring module 110 can obtain the vehicle's oil pressure / electricity data 310 through the oil pressure / electricity sensor 210. The image processing module 120 can be electrically connected to the image sensor 220, and the image processing module 120 can obtain the vehicle's image data 320 through the image sensor 220. The navigation and positioning module 130 can be electrically connected to the positioning sensor 230, and the navigation and positioning module 130 can obtain the vehicle's location data 330 through the positioning sensor 230.

[0046] See also Figure 1As shown, in some embodiments, the calculation module 140 can be electrically connected to the energy monitoring module 110, the image processing module 120, and the navigation and positioning module 130, respectively. After the energy monitoring module 110 obtains the remaining fuel or remaining battery level of the vehicle, the calculation module 140 can calculate the remaining mileage of the vehicle. The calculation module 140 can compare the remaining mileage with a preset threshold mileage. When the remaining mileage is greater than or equal to the threshold mileage, the calculation module 140 determines that the vehicle has sufficient energy and does not need to be charged. When the remaining mileage is less than the threshold mileage, the calculation module 140 determines that the vehicle has insufficient energy and requires charging. Furthermore, if the remaining mileage is less than or equal to the threshold mileage, after the image processing module 120 obtains the vehicle's image data 320 and the navigation and positioning module 130 obtains the vehicle's location data 330, the calculation module 140 further determines whether the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination in the vehicle's forward direction. When the remaining mileage is less than a threshold mileage, and the remaining mileage in the vehicle's forward direction is greater than or equal to the distance between the vehicle and the charging destination, the calculation module 140 may generate a vehicle navigation route based on the navigation and positioning module 130. When the remaining mileage is less than a threshold mileage, and the remaining mileage in the vehicle's forward direction is less than the distance between the vehicle and the charging destination, the calculation module 140 may obtain charging stations near the vehicle based on the navigation and positioning module 130 to generate a vehicle navigation route. When the remaining mileage is greater than the threshold mileage, the calculation module 140 may not generate a vehicle navigation route.

[0047] See also Figure 1As shown, in some embodiments, the calculation module 140 determines whether the remaining mileage is greater than or equal to a preset first threshold mileage. When the remaining mileage is greater than or equal to the preset first threshold mileage, it indicates that the vehicle's remaining battery or fuel is sufficient and charging is not required. The calculation module 140 may not generate a vehicle charging voice announcement. When the vehicle's remaining mileage is less than the preset first threshold mileage, it indicates that the vehicle's remaining battery or fuel is insufficient to complete the predetermined threshold mileage. If timely vehicle charging is required, the calculation module 140 may control the voice announcement module 160 to generate a vehicle charging voice announcement. When the remaining mileage is less than or equal to the first threshold mileage, the calculation module 140 may control the voice announcement module 160 to generate a vehicle charging voice announcement. If a vehicle charging instruction is received, and the remaining mileage in the vehicle's forward direction is greater than or equal to the distance between the vehicle and the charging destination, the calculation module 140 may obtain the charging destination for the vehicle from the navigation positioning module 130 to generate a vehicle navigation route. When the remaining range in the vehicle's forward direction is less than the distance between the vehicle and the charging destination, the calculation module 140 can retrieve the charging station for the vehicle using the navigation and positioning module 130 to generate a vehicle navigation route. If a user input indicates that the vehicle should not charge, the calculation module 140 can compare the remaining range with a preset second threshold range to determine whether to control the voice announcement module 160 to generate a voice announcement indicating the vehicle is charging. The calculation module 140 can also control the indication module 150 to display the information on the indicator light and display screen 240.

[0048] See also Figure 1 As shown, in some embodiments, when the remaining mileage is less than or equal to a threshold mileage, the calculation module 140 may determine, through the image processing module 120, whether the vehicle is located on a highway. When the remaining mileage is less than or equal to the threshold mileage and the vehicle is located on a highway, the calculation module 140 may further determine whether the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination in the vehicle's forward direction. When the remaining mileage is less than or equal to the threshold mileage and the vehicle is not located on a highway, the calculation module 140 may obtain charging stations near the vehicle to generate a vehicle navigation route.

[0049] See also Figure 1As shown, in some embodiments, the calculation module 140 can determine whether the vehicle has completed the charging operation through the energy monitoring module 110. When the vehicle has not completed the charging operation, the calculation module 140 generates a vehicle charging voice broadcast. And the calculation module 140 can further compare the value of the remaining mileage and the value of the distance between the vehicle and the nearest charging station according to the navigation positioning module 130 to determine whether the vehicle has traveled to the nearest charging station for charging operation. When the vehicle has completed the charging operation, the calculation module 140 again compares the value between the remaining mileage and the preset first threshold mileage to again determine whether to perform the vehicle charging operation.

[0050] See also Figure 2 As shown, in some embodiments, the present invention proposes a method for planning a vehicle charging route, which may include the following steps.

[0051] Step S10: Obtain the remaining energy of the vehicle to calculate the remaining mileage of the vehicle.

[0052] Step S20: comparing the remaining mileage with a preset threshold mileage.

[0053] Step S30: When the remaining mileage is less than the threshold mileage, determine whether the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination in the forward direction of the vehicle.

[0054] Step S40: In the forward direction of the vehicle, when the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination, a vehicle navigation route is generated.

[0055] Step S50: In the forward direction of the vehicle, when the remaining mileage is less than the distance between the vehicle and the charging destination, obtaining charging stations around the vehicle to generate a vehicle navigation route.

[0056] Step S60: When the remaining mileage is greater than or equal to the threshold mileage, no vehicle navigation route is generated.

[0057] Among them, step S10 is to obtain the remaining energy of the vehicle to calculate the remaining mileage of the vehicle.

[0058] In some embodiments, the remaining energy of the vehicle can be obtained. For example, the remaining energy of the vehicle can be the remaining fuel level of the vehicle, or the remaining energy of the vehicle can be the remaining battery level of the vehicle. The remaining range of the vehicle can be estimated based on the remaining fuel level or the remaining battery level of the vehicle.

[0059] Step S20: comparing the remaining mileage with a preset threshold mileage.

[0060] In some embodiments, the remaining mileage is compared to a preset threshold mileage. When the remaining mileage is greater than or equal to the preset threshold mileage, it indicates that the vehicle's remaining power or fuel is sufficient and no charging is required. When the remaining mileage is less than the preset threshold mileage, it indicates that the vehicle's remaining power or fuel is insufficient to complete the preset threshold mileage and that the vehicle needs to be charged promptly. For example, multiple threshold mileages can be set for a vehicle: the first threshold mileage can be set to V1 = 100km, the second threshold mileage can be set to V2 = 60km, and the third threshold mileage can be set to V3 = 30km. When the vehicle's remaining mileage is less than V1, it indicates that the vehicle needs to be charged, and a voice notification can be issued to remind the user to charge the vehicle. If the vehicle is close to its destination, the user can ignore the voice notification under V1 and continue driving. At this time, it can be determined whether the vehicle's remaining mileage is less than V2. When the remaining mileage of the vehicle is less than V2, it may indicate that the vehicle needs to be charged. At this time, a vehicle charging voice broadcast may be issued to remind the user.

[0061] Step S30: When the remaining mileage is less than the threshold mileage, determine whether the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination in the forward direction of the vehicle.

[0062] In some embodiments, when the remaining mileage is less than a threshold mileage, and in the vehicle's forward direction, the remaining mileage is determined to be greater than or equal to the distance between the vehicle and the charging destination. If the remaining mileage in the vehicle's forward direction is greater than or equal to the distance between the vehicle and the charging destination, the vehicle is traveling in the forward direction and can be charged at the charging destination. If the remaining mileage in the vehicle's forward direction is less than the distance between the vehicle and the charging destination, the vehicle is traveling in the forward direction and cannot reach the charging destination for charging.

[0063] Step S40: In the forward direction of the vehicle, when the remaining mileage is greater than or equal to the distance between the vehicle and the charging destination, a vehicle navigation route is generated.

[0064] In some embodiments, when the remaining range in the vehicle's forward direction is greater than or equal to the distance between the vehicle and the charging destination, indicating that the vehicle is traveling in the forward direction, the vehicle can be charged at the charging destination. A vehicle navigation route can then be generated, allowing the user to drive the vehicle along the vehicle navigation route to the charging destination.

[0065] Step S50: In the forward direction of the vehicle, when the remaining mileage is less than the distance between the vehicle and the charging destination, obtaining charging stations around the vehicle to generate a vehicle navigation route.

[0066] In some embodiments, when the remaining range in the vehicle's forward direction is less than the distance between the vehicle and the charging destination, it indicates that the vehicle is traveling in the forward direction and cannot reach the charging destination for charging. In this case, charging stations near the vehicle can be obtained to generate a vehicle navigation route, allowing the user to drive the vehicle along the vehicle navigation route to the charging destination.

[0067] Step S60: When the remaining mileage is greater than or equal to the threshold mileage, no vehicle navigation route is generated.

[0068] In some embodiments, when the remaining mileage is greater than or equal to the threshold mileage, it means that the vehicle can complete all driving routes within the threshold mileage setting. At this time, the vehicle navigation route may not be generated and the user can drive towards the destination.

[0069] See also Figure 3 As shown, a flow chart of a method for planning a vehicle charging route determines whether to generate a vehicle charging voice broadcast under a preset first threshold mileage. In some embodiments, step S210 may be performed first to determine whether the remaining mileage is greater than or equal to the preset first threshold mileage. When the remaining mileage is greater than or equal to the preset first threshold mileage, it indicates that the remaining power or remaining fuel of the vehicle is sufficient and no charging process is required. Step S220 may be executed to not generate a vehicle charging voice broadcast. When the remaining mileage of the vehicle is less than the preset first threshold mileage, it indicates that the remaining power or remaining fuel of the vehicle is insufficient to complete the driving distance of the preset threshold mileage and the vehicle needs to be charged in a timely manner. Step S230 may be executed to generate a vehicle charging voice broadcast.

[0070] See also Figure 4As shown, a flow chart of a method for planning a vehicle charging route receives user input on whether to perform a vehicle charging operation on the vehicle under a preset first threshold mileage and a second threshold mileage. In some embodiments, step S231 may be executed first, and when the remaining mileage is less than or equal to the first threshold mileage, a vehicle charging voice broadcast may be generated. Secondly, step S232 may be executed to receive an input instruction to charge the vehicle, and when the remaining mileage in the forward direction of the vehicle is greater than or equal to the distance between the vehicle and the charging destination, the charging destination for the vehicle to be charged may be obtained. In the forward direction of the vehicle, when the remaining mileage is less than the distance between the vehicle and the charging destination, the charging station for the vehicle to be charged may be obtained. Secondly, step S233 may be executed to receive an input instruction not to charge the vehicle, and compare the numerical value between the remaining mileage and the preset second threshold mileage to determine whether to generate a vehicle charging voice broadcast.

[0071] See also Figure 5 As shown, a flow chart of whether the driving route is located on a highway in a method for planning a vehicle charging driving route. In some embodiments, step S310 may be executed first, and when the remaining driving mileage is less than or equal to the threshold mileage, it is determined whether the vehicle is located on a highway section. When the remaining driving mileage is less than or equal to the threshold mileage, and the vehicle is located on a highway section, step S330 may be executed to determine whether the remaining driving mileage is greater than or equal to the distance between the vehicle and the charging destination in the forward direction of the vehicle. When the remaining driving mileage is less than or equal to the threshold mileage, and the vehicle is not on a highway section, step S320 may be executed to obtain charging stations around the vehicle to generate a vehicle navigation route.

[0072] See also Figure 6 As shown, a flow chart of whether the vehicle has completed the vehicle charging operation during the driving route in a method for planning a vehicle charging driving route. In some embodiments, step S410 may be executed first to determine whether the vehicle has completed the charging operation. Secondly, when the vehicle has not completed the charging operation, step S420 may be executed to generate a vehicle charging voice broadcast. And the value of the remaining mileage and the value of the distance between the vehicle and the nearest charging station may be compared to determine whether the vehicle has traveled to the nearest charging station for the charging operation. When the vehicle has completed the charging operation, step S430 may be executed to compare the value between the remaining mileage and the preset first threshold mileage again to determine again whether to perform the vehicle charging operation.

[0073] In summary, the present invention provides a vehicle charging route planning system and method that enhances human-machine interaction regarding charging reminders during driving, improves charging efficiency when the vehicle is low on energy, and increases fault tolerance in vehicle route planning. Therefore, the present invention effectively overcomes the shortcomings of the existing technology and possesses high industrial application value.
