[0031] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0032] The following describes a detection method, device, vehicle and storage medium for vehicle energy consumption prediction according to an embodiment of the present invention with reference to the accompanying drawings. In view of the problem that the vehicle energy consumption prediction in the related art mentioned in the above background technology fails to fully consider multiple factors that change in real time, cannot accurately predict vehicle energy consumption under complex circumstances, and reduces the accuracy and reliability of vehicle energy consumption prediction, the present invention provides a detection method for vehicle energy consumption prediction, in which the target driving path information of the target vehicle can be input into the energy consumption prediction model to generate an initial energy consumption prediction result of the target vehicle, then, the real-time position information of the target vehicle obtained by the target GPS simulator that meets the preset configuration conditions is used to continuously update the energy consumption prediction value of the target vehicle for the remaining mileage in the trip to obtain multiple new energy consumption prediction results, and analyze the initial energy consumption prediction result and the multiple new energy consumption prediction results to determine the final energy consumption prediction value of the target vehicle after the trip, and when the actual energy consumption value is less than or equal to the final energy consumption prediction value, generate a vehicle energy consumption prediction detection result of the target vehicle that meets the preset validity conditions, effectively improving the accuracy and reliability of the vehicle energy consumption prediction. This solves the problem that the vehicle energy consumption prediction in the related technology fails to fully consider multiple factors that change in real time, cannot accurately predict vehicle energy consumption under complex circumstances, and reduces the accuracy and reliability of vehicle energy consumption prediction.

[0033] like Figure 1 As shown, the present invention establishes a vehicle energy consumption prediction detection system, which includes: a GPS simulator, a HIL (Hardware-in-the-Loop Test Bench) test bench, a host computer, an industrial computer, and a VCU (Vehicle Control Unit). These components work together to simulate a real driving environment and verify the performance of the VCU control strategy.

[0034] Among them, the GPS simulator is used to simulate the position changes of the vehicle during actual operation; the online map path planning model and energy consumption prediction model are preset in the industrial computer to plan the optimal path and energy consumption prediction; the driver model and vehicle model are preset in the HIL test bench to simulate the driver's behavior pattern and vehicle dynamic response; the host computer is mainly responsible for recording and storing relevant data; the VCU converts the received information into specific control commands to drive the vehicle movement.

[0035] During the hardware-in-the-loop test, the system combines online maps and GPS simulators to predict the energy consumption of new energy vehicles. By comparing the actual energy consumption calculated with the vehicle model, the rationality and effectiveness of the VCU control strategy are verified, which can effectively avoid the problem of experimental resource limitations and save development cycles.

[0036] Specifically, Figure 2 A flow chart of a method for detecting vehicle energy consumption prediction provided by an embodiment of the present invention.

[0037] like Figure 2 As shown, the detection method for vehicle energy consumption prediction includes the following steps:

[0038] In step S201 , target driving path information of a target vehicle is obtained, and the target driving path information is input into an energy consumption prediction model to generate an initial energy consumption prediction result of the target vehicle.

[0039] In the embodiment of the present invention, the target vehicle is a vehicle for simulation testing; and the target driving path information is optimal driving path information.

[0040] It can be understood that the embodiment of the present invention can obtain the target driving path information of the target vehicle. For example, the optimal driving path information is determined through the online map path planning model in the following steps, and the optimal driving path information is input into the energy consumption prediction model to generate the initial energy consumption prediction result of the target vehicle, so that the energy consumption of the vehicle can be preliminarily predicted, which effectively improves the feasibility of the energy consumption prediction of the detection vehicle.

[0041] Among them, in one embodiment of the present invention, obtaining the target driving path information of the target vehicle includes: obtaining the target travel information of the target vehicle; inputting the target travel information of the target vehicle into a preset online map path planning model to generate the target driving path information of the target vehicle.

[0042] During the actual implementation process, the embodiment of the present invention can establish an online map path planning model through the industrial computer of the above-mentioned system, which can include a data management module, a path calculation module, a user interface module, a real-time update module, a performance optimization module, a security and privacy protection module, and a testing and maintenance module. By obtaining information such as the route starting point, destination, waypoints, and driving selection strategy input by the user, multiple driving routes are automatically generated, and the optimal driving route is determined to ensure the provision of efficient, accurate and safe path planning services.

[0043] In an embodiment of the present invention, the target trip information may be a vehicle's route starting point, destination, waypoints, and target driving strategy.

[0044] For example, Figure 3 The figure below shows the logic diagram for online map route planning. The online map route planning model integrates advanced GIS (Geographic Information System) and internet technologies to provide the optimal route from origin to destination. First, enter your departure point, destination, and waypoints, and select an appropriate driving strategy, such as speed priority, distance priority, or cost priority. Then, based on the online map and taking into account factors such as distance, time, and real-time traffic conditions, the system calculates multiple recommended routes and provides detailed navigation instructions in a graphical interface. Throughout the journey, the system dynamically adjusts the route based on real-time location and the latest traffic data provided by the GPS simulator, ensuring that users reach their destination efficiently and smoothly.

[0045] Among them, in one embodiment of the present invention, the target driving path information is input into the energy consumption prediction model to generate the initial energy consumption prediction result of the target vehicle, including: inputting the target driving path information into the energy consumption prediction model to determine the target driving condition of the target vehicle; generating the initial energy consumption prediction result of the target vehicle based on the target driving condition of the target vehicle, the vehicle dynamics model and the target energy efficiency characteristics.

[0046] In an embodiment of the present invention, an energy consumption prediction model can be built through the industrial computer of the above-mentioned system, including a signal receiving module, a driving condition generation module, an energy consumption prediction module and an energy consumption correction module. By receiving online map information, the driving condition is generated, and the required energy consumption is predicted based on the driving condition combined with the vehicle signal.

[0047] For example, Figure 4The following figure shows the vehicle energy consumption prediction logic diagram. After receiving route planning information from an online map, the system first generates the vehicle's driving conditions for that route based on the specific conditions of the journey, such as distance, estimated travel time, road type, traffic flow, and weather. Subsequently, using this driving condition data, combined with the vehicle's dynamic model and energy efficiency characteristics, the system predicts the vehicle's energy consumption during the journey, effectively improving the accuracy of vehicle energy consumption predictions.

[0048] It's important to note that this embodiment of the present invention takes into account various uncertainties that may arise during actual driving (such as unexpected traffic jams or weather changes). The system also dynamically adjusts and corrects the initial energy consumption forecast to ensure that the forecast is as close to actual conditions as possible. Finally, the energy consumption forecast, after this series of sophisticated processing, is output to a display interface, providing a more intuitive and real-time view of the forecast results.

[0049] In step S202, the real-time location information of the target vehicle is obtained using a target GPS simulator that meets the preset configuration conditions, and the energy consumption prediction value of the target vehicle for the remaining mileage in the trip is continuously updated based on the real-time location information to obtain multiple new energy consumption prediction results, and the initial energy consumption prediction result and the multiple new energy consumption prediction results are analyzed to determine the final energy consumption prediction value of the target vehicle after the trip.

[0050] In the embodiment of the present invention, the preset configuration condition is a condition for performing corresponding configuration of the GPS simulator according to the planned driving path information.

[0051] It can be understood that the embodiment of the present invention can use a target GPS simulator that meets the configuration conditions to obtain the real-time location information of the target vehicle, so as to obtain the latest road information in real time, and continuously update the energy consumption prediction value of the remaining mileage based on the real-time location information, continuously obtain new energy consumption prediction results, and after the vehicle is completed, all energy consumption prediction results are summarized and analyzed to determine the final energy consumption prediction value of the target vehicle after the trip, that is, when the target vehicle arrives at the destination, the final predicted energy consumption value of the entire journey is generated and displayed, which effectively improves the real-time and accuracy of the vehicle energy consumption prediction.

[0052] Among them, in one embodiment of the present invention, the real-time position information of the target vehicle is obtained by using a target GPS simulator that meets the preset configuration conditions, including: determining the target geographical environment, target driving trajectory and target signal interference intensity of the target vehicle based on the target driving path information, and setting the dynamic driving parameters of the target vehicle; configuring the initial GPS simulator using the target geographical environment, target driving trajectory, target signal interference intensity and dynamic driving parameters to generate a target GPS simulator that meets the preset configuration conditions; and obtaining the real-time position information of the target vehicle using the target GPS simulator that meets the preset configuration conditions.

[0053] In an embodiment of the present invention, the GPS simulator of the above-mentioned system can be configured to configure relevant scenarios and generate trajectories based on the generated driving path information; at the same time, the dynamic parameters of the vehicle, such as speed, acceleration, direction, etc., can be set; finally, factors such as signal strength interference can be adjusted to simulate signal strength changes in different environments.

[0054] For example, if Figure 5 Figure 2 shows the GPS simulator configuration process. When configuring the GPS simulator, you first need to set up a scenario. This involves introducing route planning information to create a simulated geographical environment, including city streets, highways, or mountain roads. Weather conditions, such as sunny, rainy, and foggy, are also included. These settings ensure that the test environment is as close to real-world scenarios as possible, thereby improving test effectiveness.

[0055] Next, we set up the trajectory. By importing the planned road data, we create a driving trajectory, including the starting point, destination, and waypoints, which is completely consistent with the planned route, thus simulating complex and realistic driving routes. These routes can be used to simulate vehicle driving under different road conditions, helping to test the system's performance under various driving conditions. Through detailed trajectory settings, we can ensure that the test covers all possible driving scenarios.

[0056] Next, configure dynamic parameters. This involves defining the vehicle's speed profile, including acceleration, deceleration, constant speed, and variable speed driving, to simulate different driving behaviors. Furthermore, set the vehicle's driving direction, including turns and lane changes, to simulate complex driving maneuvers. Furthermore, set the simulation start time and duration to ensure smooth execution of the test plan. By setting these dynamic parameters, the GPS simulator generates realistic driving data, enabling comprehensive testing of the VCU under test.

[0057] Finally, adjusting signal conditions involves adjusting signal strength to simulate signal reception in different environments, such as urban areas with tall buildings versus open rural areas. Setting multipath parameters to simulate the effects of signal reflection and refraction is particularly important for testing system performance in complex environments. Furthermore, interference from other radio signals can be introduced to test the system's interference resistance. By adjusting these signal conditions, test results more closely resemble real-world conditions, thereby improving test reliability and effectiveness.

[0058] In step S203, the actual energy consumption value of the target vehicle after the trip is obtained, and when the actual energy consumption value is less than or equal to the final energy consumption prediction value, a vehicle energy consumption prediction detection result of the target vehicle that meets the preset validity conditions is generated.

[0059] In the embodiment of the present invention, the preset validity condition is a condition that the VCU control strategy is reasonable and effective.

[0060] It can be understood that the embodiment of the present invention can obtain the actual energy consumption value of the target vehicle after the end of the trip. For example, the actual energy consumption value of the target vehicle after the end of the trip is calculated through the relevant parameters of the vehicle model built on the HIL test bench, and when the actual energy consumption value is less than or equal to the final energy consumption prediction value, a vehicle energy consumption prediction detection result of the target vehicle that meets the preset validity conditions is generated, that is, the VCU control strategy is reasonable and effective and does not need to be adjusted; for example, the embodiment of the present invention can evaluate and verify the rationality and effectiveness of the VCU control strategy based on the comparison results of the actual energy consumption value and the final energy consumption prediction value. The smaller the actual energy consumption value is than the final energy consumption prediction value, the more reasonable and effective the VCU control strategy is.

[0061] In this embodiment of the present invention, a driver model and a vehicle model can be built using the HIL test bench of the aforementioned system. The driver model is designed to mimic the behavior of a real driver, including reaction time and acceleration / deceleration pedal opening. The vehicle model includes a dynamics model, an electric drive system model, a battery management system model, a braking system model, a tire model, an aerodynamics model, and a thermal management model. Data signals are exchanged based on the energy transmission relationship between the models, and the vehicle model is used to simulate the various characteristics of a real vehicle.

[0062] For example, Figure 6Figure 2 shows a schematic diagram of the driver model and vehicle model built in the HIL test bench. The driver model can be considered a technical means of simulating driving behavior, imitating how a real driver adjusts operations such as steering, acceleration, or deceleration based on the vehicle's current operating conditions. Specifically, the driver model receives information about the vehicle's current actual state (such as speed and direction) and compares it with the desired target state to identify the difference between the two. This error is then processed through a PI (Proportional-Integral) control mechanism, converted into specific control commands (such as adjusting the throttle opening or changing the steering wheel angle). These commands are then sent back to the vehicle model for execution, achieving precise control of the vehicle's state. The entire process forms a continuous feedback loop that ensures the vehicle drives according to the predetermined target state.

[0063] The vehicle model also includes a dynamics model covering longitudinal, lateral, and vertical dynamics; an electric drive system model encompassing the motor, inverter, and controller; a battery management system model covering battery characteristics, thermal management, and charging; a braking system model covering regenerative braking, hydraulic braking, and brake fusion; a tire model covering rolling resistance, cornering force, and grip; an aerodynamic model covering drag coefficient and lift coefficient; and a thermal management model covering motor and inverter heat dissipation, as well as battery pack heat dissipation. The combined performance of these subsystems directly impacts the overall vehicle performance. The control strategy implemented by the vehicle's VCU, combined with input from external operating conditions, effectively enables vehicle energy consumption testing.

[0064] Optionally, in one embodiment of the present invention, after generating a vehicle energy consumption prediction test result of the target vehicle that meets preset validity conditions, it also includes: generating a vehicle energy consumption prediction test report based on the initial energy consumption prediction result, the final energy consumption prediction value and the actual energy consumption value; sending the test report to a preset terminal to display the vehicle information, test route, energy consumption prediction data and VCU control strategy evaluation results in the test report on the preset terminal.

[0065] In some embodiments, the embodiments of the present invention can generate a vehicle energy consumption prediction test report based on the initial energy consumption prediction result at the time of vehicle departure, the updated final energy consumption prediction value, and the actual energy consumption value after the vehicle actually drives. The report content may include vehicle information (such as model, battery status, etc.), test route details, changes in energy consumption prediction, and evaluation results of the vehicle VCU control strategy, etc., and the test report is displayed on the technician's computer or mobile phone, so that the technician can clearly see the difference between the prediction and the actual situation, and can understand the accuracy of the vehicle energy consumption prediction.

[0066] For example, if Figure 7The figure below is a schematic diagram of the vehicle energy consumption prediction testing and implementation process. First, a cloud-based online map is used to plan and generate a route. The GPS simulator is then configured based on the planned route information, including the scenario, trajectory, dynamic parameters, and related signals. Energy consumption is then predicted using the route planning information combined with vehicle-related parameters. Simultaneously, the driver and vehicle models test the VCU's energy management control strategy based on these planned routes. During operation, the route is dynamically adjusted based on the real-time location and latest traffic data provided by the GPS simulator, achieving dynamic updates. At the end of the run, the overall energy consumption prediction is displayed. By comparing it with the actual energy consumption calculated based on the vehicle model's related parameters, the rationality and effectiveness of the VCU control strategy are evaluated and verified. The closer the calculated value is to or smaller than the predicted value, the more rational and effective the VCU control strategy is, and vice versa.

[0067] The embodiment of the present invention introduces a GPS simulator to simulate geographic location, speed, time and other navigation parameters, which can simulate various driving conditions and environmental changes, and can complete the prediction and calculation of vehicle energy consumption without actual road tests, thereby greatly improving the test efficiency. In addition, the driving conditions generated after online map path planning are also introduced. The online map path planning can generate test conditions according to the specific driving route and traffic conditions, making the test closer to the real driving environment, and can generate a variety of driving scenarios, including urban roads, highways, rural roads, etc., to comprehensively evaluate the accuracy of the energy consumption prediction model and the vehicle's energy consumption performance. The embodiment of the present invention can verify the rationality and effectiveness of the VCU control strategy, and can replace the actual vehicle verification and calibration of the vehicle energy management system performance, so as to better optimize the energy management system and control strategy.

[0068] According to the detection method for vehicle energy consumption prediction proposed in an embodiment of the present invention, the target driving path information of the target vehicle can be input into the energy consumption prediction model to generate the initial energy consumption prediction result of the target vehicle. Then, the real-time position information of the target vehicle obtained by the target GPS simulator that meets the preset configuration conditions is used to continuously update the energy consumption prediction value of the target vehicle for the remaining mileage in the trip to obtain multiple new energy consumption prediction results, and the initial energy consumption prediction result and the multiple new energy consumption prediction results are analyzed to determine the final energy consumption prediction value of the target vehicle after the trip ends. When the actual energy consumption value is less than or equal to the final energy consumption prediction value, a vehicle energy consumption prediction detection result that meets the preset effective conditions is generated for the target vehicle, thereby effectively improving the accuracy and reliability of the vehicle energy consumption prediction. Thus, the problem that the vehicle energy consumption prediction in the related art fails to fully consider the various factors that change in real time, cannot accurately predict the vehicle energy consumption under complex circumstances, and reduces the accuracy and reliability of the vehicle energy consumption prediction is solved.

[0069] Next, the detection device for predicting vehicle energy consumption according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0070] Figure 8 It is a block diagram of a detection device for predicting vehicle energy consumption according to an embodiment of the present invention.

[0071] like Figure 8 As shown, the vehicle energy consumption prediction detection device 10 includes: an acquisition module 100, a determination module 200 and a detection module 300.

[0088] It should be noted that the above explanation of the embodiment of the detection method for vehicle energy consumption prediction is also applicable to the detection device for vehicle energy consumption prediction of this embodiment, and will not be repeated here.

[0089] According to the detection device for predicting vehicle energy consumption proposed in an embodiment of the present invention, the target driving path information of the target vehicle can be input into the energy consumption prediction model to generate the initial energy consumption prediction result of the target vehicle. Then, the real-time position information of the target vehicle obtained by the target GPS simulator that meets the preset configuration conditions is used to continuously update the energy consumption prediction value of the target vehicle for the remaining mileage in the trip to obtain multiple new energy consumption prediction results, and the initial energy consumption prediction result and the multiple new energy consumption prediction results are analyzed to determine the final energy consumption prediction value of the target vehicle after the trip ends. When the actual energy consumption value is less than or equal to the final energy consumption prediction value, a vehicle energy consumption prediction detection result that meets the preset effective conditions is generated for the target vehicle, thereby effectively improving the accuracy and reliability of the vehicle energy consumption prediction. Thus, the problem that the vehicle energy consumption prediction in the related art fails to fully consider the various factors that change in real time, cannot accurately predict the vehicle energy consumption under complex circumstances, and reduces the accuracy and reliability of the vehicle energy consumption prediction is solved.
