[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0034] It should be noted that the terms "first", "second", etc. in this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0035] Figure 1 Schematic diagram of an implementation environment provided by the embodiment of the present application. Figure 1 As shown, the implementation environment may include a vehicle 101 and a vehicle control system 102. The vehicle control system 102 is used to control the vehicle 101 to perform corresponding operations. The vehicle control system 102 may be located in the vehicle 101, for example, the vehicle control system 102 is a vehicle-mounted terminal; the vehicle control system 102 may also be located outside the vehicle 101, for example, the vehicle control system 102 is a cloud control system.

[0036] The vehicle control system 102 may be an independent server, or the vehicle control system 102 may be a server cluster composed of a plurality of servers implementing different functions respectively, or the vehicle control system 102 may be a cloud computing center.

[0037] The vehicle 101 may be a vehicle with intelligent assisted driving function, and the vehicle 101 may have hardware facilities such as cameras, millimeter wave radars, laser radars, positioning sensors, and communication sensors. The vehicle 101 obtains real-time vehicle information and historical vehicle information through the configured hardware facilities; the vehicle control system 102 may determine the vehicle range under the current battery charge state based on the real-time vehicle information and historical vehicle information of the vehicle 101.

[0038] The vehicle 101 may also have a wireless communication function. A communication module supporting wireless communication technology or wired communication technology may be provided in the vehicle 101. The vehicle 101 exchanges data with the vehicle control system 102 through the communication module.

[0039] Based on the above Figure 1 In the implementation environment shown, the present application embodiment provides a method for determining the cruising range of a vehicle. Figure 2 As shown, this method can be Figure 1 The method may be performed by the vehicle 101 in the vehicle control system 102, or may be performed interactively by the vehicle 101 and the vehicle control system 102. The method may include steps 201 to 204.

[0040] In step 201, real-time vehicle information and historical travel data of the vehicle are obtained, the real-time vehicle information includes a first vehicle parameter corresponding to the driving status of the vehicle at the current moment, the first vehicle parameter includes a first battery state of charge and a current vehicle range corresponding to the first state of charge, the historical travel data includes a second vehicle parameter corresponding to the driving status of the vehicle at a historical moment, the second vehicle parameter includes a second battery state of charge and a first historical range corresponding to the second battery state of charge.

[0041] In an exemplary embodiment of the present application, the vehicle may be a new energy vehicle with an on-board intelligent system, wherein the new energy vehicle may be a vehicle driven by one or more driving modes, and the driving mode at least includes electric energy driving. For example, the new energy vehicle may include but is not limited to a battery electric vehicle (BEV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), an extended-range electric vehicle (REEV), and a fuel cell vehicle (FCEV).

[0042] The vehicle-mounted intelligent system has an information acquisition device, through which real-time vehicle information can be acquired, and the acquired real-time vehicle information is stored to obtain historical travel data. Among them, the real-time vehicle information may include the first vehicle parameter and the first environmental information corresponding to the driving state of the vehicle at the current moment. The vehicle may be configured with an information acquisition device, and the information acquisition device may include but is not limited to a camera, a millimeter wave radar, a laser radar, and a plurality of sensors, wherein the sensor may include an inertial sensor, a speed sensor, an acceleration sensor, an engine speed sensor, and a temperature sensor, etc. Through the information acquisition device installed in the vehicle, the first vehicle parameter of the vehicle and the first environmental information corresponding to the environment in which the vehicle is located can be acquired in real time, wherein the first vehicle parameter may include but is not limited to the speed parameter, acceleration parameter, position parameter of the vehicle at the current moment, the speed parameter of the engine, the torque parameter, the temperature parameter, the parameters of the on-board electrical device, the driving mode parameter, the energy recovery parameter, the vehicle load parameter, and the tire pressure parameter; the first environmental information includes but is not limited to the temperature parameter, humidity parameter, obstacle, and light parameter of the external environment in which the vehicle is currently located. The historical travel data includes the second vehicle parameters and the second environmental information corresponding to the driving status of the vehicle at the historical moment, wherein the second vehicle parameters are similar to the first vehicle parameters, and the second environmental information is similar to the first environmental information, and no further elaboration is given here. It should be noted that the real-time vehicle information and historical travel data are illustrative in this application, and the information obtained can be set based on the actual situation of the vehicle, and this application does not impose any restrictions on this.

[0043] In step 202, the selected historical travel data is determined in the historical travel data using the reference similarity between the first vehicle parameter and the second vehicle parameter, and the historical duration of the selected historical travel data is less than or equal to the threshold duration, and the historical duration is the duration from the historical moment to the current moment.

[0044] In an exemplary embodiment of the present application, the historical time when the historical travel data was generated is determined, and the historical travel data is first screened using the historical time and the historical duration of the current time to obtain historical travel data whose historical duration is less than or equal to the threshold duration. For example, the threshold duration can be set to 3 months or 6 months. The threshold duration can be set based on the change in the battery performance of the vehicle itself, and the present application does not limit this.

[0045] By first filtering the historical travel data by threshold duration and historical duration, the recent travel data of the vehicle can be obtained. The recent data of the vehicle can more accurately reflect the current state and performance of the vehicle, especially the battery performance changes less in a short period of time. When the filtered historical travel data is used to calculate the vehicle's cruising range in the subsequent process, the accuracy of the determined vehicle's cruising range can be improved. In addition, by first filtering the historical travel data, the amount of calculation for subsequent similarity calculation based on the historical travel data can be reduced, and the data processing efficiency can be improved.

[0046] Exemplarily, after the first screening of the historical travel data, a second screening may be performed to obtain the selected historical travel data. The reference similarity may include a third similarity, and the process of obtaining the selected historical travel data includes: determining the third similarity between the first vehicle parameter and the second vehicle parameter, determining the second vehicle parameter whose third similarity is greater than or equal to the second similarity threshold as the reference vehicle parameter; and determining the historical travel data corresponding to the reference vehicle parameter as the selected historical travel data.

[0047] Optionally, before determining the third similarity between the first vehicle parameters and the second vehicle parameters, the first vehicle parameters and the second vehicle parameters may be preprocessed to remove abnormal values ​​or missing values ​​in the first vehicle parameters and the second vehicle parameters, and the first vehicle parameters and the second vehicle parameters may be normalized so that the first vehicle parameters and the second vehicle parameters are compared on the same dimension.

[0048] The first vehicle parameter and the second vehicle parameter may contain multiple parameters. The first feature vector and the second feature vector are constructed using the parameter types contained in the first vehicle parameter and the second vehicle parameter. The first feature vector and the second feature vector may be multidimensional vectors, and the dimensions and parameter types of the vectors may correspond one to one. For example, the parameters of the on-board electrical device, the driving mode parameter, the energy recovery parameter, the vehicle load parameter, and the tire pressure parameter may be respectively used as a dimensional feature vector, and the feature vectors of each dimension are integrated to obtain the first feature vector and the second feature vector. Among them, the integration of the feature vectors of each latitude may be to fill the feature values ​​of each vehicle parameter into the corresponding dimension in sequence according to the defined dimensional order. For example, the first vehicle parameters are: the on-board electrical device parameter is 0.5, the driving mode parameter is 2, the energy recovery parameter is 0.8, the vehicle load parameter is 1500kg, and the tire pressure parameter is 2.5bar, then the first feature vector can be expressed as [0.5, 2, 0.8, 1500, 2.5]. It should be noted that the process of obtaining the second feature vector is similar to the process of obtaining the first feature vector, which will not be repeated here. In addition, the first eigenvector and the second eigenvector are exemplary illustrations and may be actually determined based on the first vehicle parameter and the second vehicle parameter.

[0049] Then, at least one of the cosine similarity, the Euclidean distance, or the Hatton distance between the first eigenvector and the second eigenvector may be calculated to determine a third similarity between the first eigenvector and the second eigenvector.

[0050] The calculation of the cosine similarity between the first eigenvector and the second eigenvector is used as an example for explanation. The cosine similarity cosθ between the first eigenvector A and the second eigenvector B can be calculated by formula (1):

[0051]

[0052] In the above formula (1), ||A|| and ||B|| represent the modulus of vectors A and B, respectively. The value range of cosine similarity is between -1 and 1. The closer the value is to 1, the more similar the first eigenvector and the second eigenvector are. The closer the value is to -1, the less similar the first eigenvector and the second eigenvector are. By calculating the similarity of the first eigenvector and the second eigenvector, the third similarity of the first vehicle parameter and the second vehicle parameter can be obtained.

[0053] The third similarity is compared with the second similarity threshold, and if the third similarity is greater than or equal to the second similarity threshold, the corresponding second vehicle parameter is determined as the reference vehicle parameter, and the historical travel data corresponding to the reference vehicle parameter is used as the selected historical travel data. The second similarity threshold can be set based on the actual situation of the vehicle, and this application does not limit this.

[0054] It should be noted that the method of calculating the third similarity between the first vehicle parameter and the second vehicle parameter in the present application is an exemplary description, and other methods can also be used to calculate the third similarity, and the present application does not impose any limitation on this.

[0055] The technical solution provided in the embodiment of the present application determines the selected historical travel data through the third similarity between the first vehicle parameter and the second vehicle parameter. The selected historical travel data is similar to the current vehicle driving travel data. In the subsequent process, when the selected historical travel data is used to determine the vehicle's cruising range, the accuracy of the vehicle's cruising range can be improved.

[0056] In step 203 , a weight corresponding to the selected historical travel data is determined based on the reference similarity, and a second historical cruising range corresponding to the second battery state of charge is determined using the weight and the first historical cruising range of the selected historical travel data.

[0057] In an exemplary embodiment of the present application, the reference similarity may further include a first similarity, and the process of determining a second historical cruising range corresponding to the second battery state of charge may include steps 2031 to 2035 .

[0058] In step 2031, the second battery state of charge of the selected historical travel data is divided into a plurality of state of charge intervals, and a first similarity between a second vehicle parameter and a first vehicle parameter in any state of charge interval is determined, wherein the energy consumption of the vehicle in the same state of charge interval remains unchanged.

[0059] For example, the second battery state of charge in the selected historical travel data is SOC n Change to 0%, the second battery state of charge 0% ~ SOC n Divide into multiple state of charge intervals. In the process of dividing the state of charge intervals, the division can be based on the battery energy consumption of the vehicle. In any state of charge interval, the battery energy consumption of the vehicle remains unchanged; in different state of charge intervals, the battery energy consumption of the vehicle can be the same or different. For example, the state of charge intervals can be divided into [0%, SOC1), [SOC1, SOC2)…[SOC n-1 , SOC n ], obtain the corresponding second vehicle parameter in each state of charge interval, and calculate the first similarity between the second vehicle parameter and the first vehicle parameter in each state of charge interval. It should be noted that for different selected historical travel data, the divided state of charge intervals can be the same or different, and can be divided separately based on the second vehicle parameter of each selected historical travel data. In addition, the process of calculating the first similarity is similar to the process of calculating the third similarity, which will not be described in detail here.

[0060] In step 2032 , the state of charge interval having a first similarity greater than or equal to a first similarity threshold is determined as a reference state of charge interval.

[0061] Exemplarily, the first similarity between the second vehicle parameter and the first vehicle parameter in each state of charge interval is compared with the first similarity threshold to obtain a state of charge interval in which the first similarity is greater than or equal to the first similarity threshold, and the state of charge interval is used as a reference state of charge interval. It should be noted that the first similarity threshold can be set based on the historical travel data of the vehicle. The battery energy consumption of the vehicle may change throughout the historical travel data. For example, turning on the car air conditioner, using the car audio, or changes in traffic conditions will cause changes in battery energy consumption. The first similarity threshold can be set to be greater than the third similarity threshold, and a reference state of charge interval that is more similar to the current vehicle state is determined in the historical travel data. In the subsequent process, the accuracy of determining the vehicle's cruising range using the reference state of charge interval can be improved.

[0062] In step 2033, a weight corresponding to the reference state of charge interval is determined based on the first similarity.

[0063] In one embodiment of the present application, after determining the first similarity corresponding to the reference state of charge interval, the weight corresponding to the reference state of charge interval can be determined based on the number of reference state of charge intervals and the first similarity. The larger the value of the first similarity of the reference state of charge interval, the larger the corresponding weight. For example, the first similarity of the reference state of charge interval can be directly normalized, and the normalized value can be used as the weight corresponding to the reference state of charge interval.

[0064] In one embodiment of the present application, after determining the first similarity corresponding to the reference state of charge interval, the weight of the reference state of charge interval can be determined by the third similarity, the number of reference state of charge intervals, and the first similarity. For example, the selected historical travel data is x, and the corresponding first weights are A1, A2...Ax, and the sum of A1, A2 to Ax is 1; for the selected historical travel data with the first weight A1, the number of reference state of charge intervals is y, and the corresponding second weights are B1, B2...By, and the sum of B1, B2 to By is 1; for the reference state of charge interval with the second weight B1, the average of the first weight A1 and the second weight B1 can be used as the final weight corresponding to the reference state of charge interval.

[0065] It should be noted that the above embodiment is an exemplary description of the process of determining the weight, and other methods can also be used to determine the weight of the reference state of charge interval. The present application does not limit this. In addition, the process of determining the first weight and the second weight can be similar to the process of determining the weight corresponding to the reference state of charge interval in the previous embodiment, and will not be repeated here.

[0066] In step 2034, a plurality of reference cruising ranges corresponding to the second battery state of charge in the reference state of charge interval are obtained.

[0067] In an exemplary embodiment of the present application, a reference state of charge interval may include multiple second battery states of charge, and in the selected historical travel data where the reference state of charge interval is located, a reference range corresponding to the second battery state of charge in the reference state of charge interval is obtained. For example, the reference state of charge interval is [30% to 35%), which includes 5 second battery states of charge, namely 30%, 31%, 32%, 33% and 34%. When the second battery state of charge is obtained, the vehicle's range is used as the reference range.

[0068] In step 2035, a second historical cruising range corresponding to the second battery state of charge is determined using the weight corresponding to the reference state of charge interval and the reference cruising range.

[0069] Exemplarily, for any second battery state of charge, the weight of the reference state of charge interval in which the second battery state of charge is located and the reference cruising range of the second battery state of charge are used for calculation to obtain a weighted average of the reference cruising range corresponding to the second battery state of charge, and the weighted average is used as the second historical cruising range corresponding to the second battery state of charge. For example, the second battery state of charge is 30%, and the number of reference state of charge intervals is m. Based on the weight of the reference state of charge interval in which 30% is located and the reference cruising range of the second battery state of charge of 30%, the weighted average of m reference cruising ranges is calculated to obtain the second historical cruising range corresponding to the second battery state of charge of 30%.

[0070] The reference state of charge interval corresponds to three selected historical travel data, the battery state of charge changes from 100% to 10%, and the reference state of charge interval is 10%. Table 1 is a partial second vehicle parameter table in the reference state of charge interval.

[0071] Table 1

[0072]

[0073]

[0074] Referring to Table 1, the selected historical trip data corresponding to the reference state of charge interval are the first trip, the second trip and the third trip, each trip data can be divided into 9 state of charge intervals, each state of charge interval can correspond to a weight, and each state of charge interval can include multiple second battery states of charge and the reference cruising range corresponding to the second battery state of charge. Continuing to take the second battery state of charge of 30%, S13, S23 and S33 are respectively the first historical cruising range corresponding to the second battery state of charge of 30% as an example, then the second historical cruising range corresponding to the second battery state of charge of 30% S = (A3*S13+B3*S23+C3*S33) / 3.

[0075] The technical solution provided by the exemplary embodiment of the present application can reduce the calculation error of the cruising range caused by the change of vehicle energy consumption during the whole driving process by dividing the second battery state of charge of the selected historical travel data into multiple state of charge intervals and determining the first similarity between the second vehicle parameter corresponding to the state of charge interval and the first vehicle parameter. In addition, by calculating the second historical cruising range through the weight of the reference state of charge interval in which the second battery state of charge is located and the reference cruising range, a more accurate second historical cruising range can be obtained, which is conducive to improving the accuracy of determining the current vehicle cruising range based on the second historical cruising range in the subsequent process.

[0076] In step 204, a correction parameter of the second historical cruising range is determined, and a target vehicle cruising range corresponding to the vehicle at the first battery state of charge is determined using the correction parameter, the second historical cruising range, and the current vehicle cruising range.

[0077] In an exemplary embodiment of the present application, the real-time vehicle information may further include first environmental information, and the historical travel data may further include second environmental information, wherein the first environmental information may be information about the environment in which the vehicle is located at the current moment, and the second environmental information may be information about the environment in which the vehicle is located at a historical moment. The relevant contents of the first environmental information and the second environmental information are described in detail in step 201, and will not be described in detail here.

[0078] The process of determining the correction parameters of the second historical cruising range may include: determining a second similarity between the second environmental information corresponding to the reference state of charge interval and the first environmental information; determining a first correction factor corresponding to the reference cruising range based on the second similarity, and determining a second correction factor corresponding to the reference cruising range based on the first similarity; and determining the correction parameters corresponding to the second historical cruising range based on the first correction factor and the second correction factor.

[0079] Exemplarily, the different environments in which the vehicle is driving will affect the vehicle's range. For example, in a low-temperature environment, the battery activity is weakened, and the discharge capacity is also weakened, thereby reducing the energy conversion efficiency and resulting in a reduction in the range; in a high-temperature environment, the battery activity is enhanced, and the discharge capacity is also enhanced, thereby increasing the energy conversion efficiency, resulting in a relative increase in the range. For another example, when the vehicle is in an urban environment, the vehicle needs to start and stop frequently, which will increase power consumption and affect the range; when the vehicle is in a high-speed environment, driving with the wind or against the wind will affect the resistance of the car. When driving against the wind, the car needs to consume more electricity to overcome the resistance. Therefore, it is necessary to determine the second similarity between the second environmental information corresponding to the reference state of charge interval and the first environmental information. The second similarity can characterize the similarity between the current vehicle's driving environment and the vehicle's driving environment at a historical moment.

[0080] It should be noted that the process of determining the second similarity may be similar to the process of determining the third similarity. Please refer to the relevant description of determining the third similarity above, and no further details will be given here.

[0081] After determining the second similarity, the first correction factor can also be determined based on the second similarity. According to the size of the second similarity, the first correction factor can be determined by using a table lookup or a correction function. The first correction factor can characterize the impact of the difference between the current driving environment and the historical driving environment on the cruising range. Since the second vehicle parameter of the reference state of charge interval is not exactly the same as the parameter of the current vehicle driving state during vehicle driving, the second correction factor can be determined based on the first similarity between the second vehicle parameter of the state of charge interval and the first vehicle parameter, wherein the process of determining the second correction factor can be similar to the process of determining the first correction factor, which will not be repeated again. Then the first correction factor and the second correction factor are combined, and the combination may include but is not limited to adding, multiplying and weighted averaging the first correction factor and the second correction factor to obtain the correction parameter.

[0082] It should be noted that the process of determining the first correction factor, the second correction factor and the correction parameter in this application is an exemplary description, and other methods can also be used to calculate the correction factor and the correction parameter, and this application does not limit this.

[0083] The technical solution provided by the exemplary embodiment of the present application determines a first correction factor by the difference between first environmental information of the current vehicle driving environment and second environmental information of the vehicle driving environment at a historical moment, determines a second correction factor by the difference between vehicle parameters at a current moment and vehicle parameters at a historical moment, and uses the first correction factor and the second correction factor to determine correction parameters for the second historical cruising range, which helps to reduce the error in vehicle cruising range caused by differences in environmental information and differences in the vehicle's own parameters.

[0084] After determining the correction parameter, the target vehicle cruising range can also be determined based on the correction parameter. The process of determining the target vehicle cruising range may include: determining the target battery state of charge in a reference state of charge interval; when the first battery state of charge is the same as the target battery state of charge, correcting the second historical cruising range based on the correction parameter, and determining the target vehicle cruising range using the corrected second historical cruising range and the current cruising range.

[0085] In an exemplary embodiment of the present application, the reference state of charge interval may include a plurality of second battery states of charge that change continuously, and the target battery state of charge is determined among the plurality of second battery states of charge that change continuously. The target battery state of charge may be any second battery state of charge, and the target battery state of charge may be determined based on actual needs (e.g., driving distance, charging convenience, and battery power). Exemplarily, when the battery power is sufficient, a smaller number of target battery states of charge may be selected in the reference state of charge interval; when the battery power is low, a larger number of target battery states of charge may be selected in the reference state of charge interval.

[0086] For example, when the reference state of charge interval is [80% to 90%), one target battery state of charge can be selected, and the target battery state of charge can be 85%; when the reference state of charge interval is [20% to 30%), five target battery states of charge can be selected, and the target battery states of charge are 20%, 22%, 24%, 26% and 28% respectively.

[0087] During the current vehicle driving process, the first battery state of charge corresponding to the vehicle battery decreases accordingly. When the first battery state of charge is the same as the target battery state of charge, it is confirmed whether the current vehicle range meets the correction conditions. If the current vehicle range meets the correction conditions, the corrected second range is used as the target vehicle range corresponding to the vehicle under the first battery state of charge, that is, the corrected vehicle range.

[0088] Exemplarily, the current vehicle cruising range is compared with the corrected second cruising range corresponding to the target state of charge. If the difference between the current vehicle's real-time cruising range and the corrected second cruising range is less than the cruising range threshold, the vehicle's cruising range may not be corrected temporarily; if the difference between the current vehicle's real-time cruising range and the corrected second cruising range is greater than or equal to the cruising range threshold, the vehicle's real-time cruising range may be gradually corrected during the vehicle's driving process until the difference between the vehicle's cruising range and the corrected second cruising range is less than the cruising range threshold, thereby obtaining the target vehicle cruising range corresponding to the vehicle at the first battery state of charge. The cruising range threshold may be set based on the actual situation of the vehicle, and this application does not limit this.

[0089] Figure 3 is a schematic diagram of a vehicle cruising range curve provided in an embodiment of the present application, such as Figure 3 As shown, the horizontal axis is the driving time (seconds), the vertical axis is the battery charge state, and the vehicle cruising range curve may include the vehicle cruising range curve before correction and the vehicle cruising range curve after correction, which is composed of Figure 3 It can be seen that the vehicle range curve after correction is somewhat different from the vehicle range curve before correction, and the difference between the two increases with time.

[0090] The technical solution provided by the exemplary embodiment of the present application determines a target battery state of charge in a reference state of charge interval, and corrects the vehicle range when the first battery state of charge is the same as the target battery state of charge. The vehicle range can be corrected in time when the vehicle range has a small deviation, and the correction process can be a smooth transition to avoid a jump in the vehicle range after the correction, thereby improving the driving experience.

[0091] The technical solution provided by the exemplary embodiment of the present application determines the selected historical travel data by reference similarity and historical duration between the first vehicle parameter in the real-time vehicle information and the second vehicle parameter in the historical travel data. The selected historical travel data is data similar to the first vehicle parameter of the current vehicle, which can improve the accuracy of determining the vehicle's cruising range based on the selected historical travel data in the subsequent process, and the selected historical travel data is processed in the subsequent process, which can improve the data processing efficiency compared to processing all historical travel data. By determining the weight corresponding to the selected historical travel data by reference similarity, determining the second historical cruising range using the weight and the first historical cruising range, and correcting the second historical cruising range using the correction parameter, and determining the target vehicle cruising range based on the corrected second historical cruising range and the current vehicle cruising range, the accuracy of the determined target vehicle cruising range can be improved.
