[0002] The present application relates to the technical field of extended-range vehicles, and in particular to a driving mode determination method, device, electronic device, and storage medium. Background Art

[0003] An extended-range electric vehicle is a pure electric vehicle that adds an internal combustion engine to charge the power battery or directly drive the motor to increase the range, thereby overcoming the short range of electric vehicles. Usually, an extended-range electric vehicle can truly achieve zero fuel consumption, zero pollution, and zero emissions within a certain driving time range. Extended-range electric vehicles not only overcome the problems of short range and long charging time, but also avoid the complex internal control logic of the car, so they have received widespread attention in recent years.

[0004] Extended-range vehicles currently have three driving modes: pure electric priority mode, automatic range extension mode, and fuel priority mode. According to the strategy of starting the range extender of the extended-range vehicle's vehicle controller (VCU), in the fuel priority mode, the range extender will also be started when the battery power is high. At this time, the driver cannot know the real-time driving conditions of the vehicle, so he will not choose a more suitable driving mode according to the real-time conditions of the vehicle, and will continue the fuel priority mode. In this way, fuel energy supply is still not economical when the battery power is sufficient, and it will produce unnecessary exhaust emissions, causing ecological damage. Summary of the Invention

[0018] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Example 1 As mentioned in the background technology, to address the problems in the prior art, this application proposes an intelligent driving mode prediction method, comprising the following steps: S100. In response to a charging signal, the charging signal including a start charging signal and a stop charging signal, storing a first charging time at which the start charging signal is received and a second charging time at which the stop charging signal is received. Optionally, when a battery management system (BMS) detects a trigger signal generated by contact and engagement between a vehicle charging socket and a charging terminal and a current signal indicating current flowing into the vehicle, the start charging signal is generated, and the VCU stores the time of receipt as the first charging time. When the vehicle charging socket and the charging terminal are separated, the stop charging signal is generated, and the VCU stores the time of receipt as the second charging time. S101. Calling a charging information database to obtain the number of charges corresponding to the second charging moment adjacent to the first charging moment; the charging information database includes: a set of the first charging moment and the second charging moment corresponding to each charging signal, and the number of charges corresponding to the set; optionally, the user issues a charging signal once for each charging action of the vehicle, and the charging signal corresponds to a start time and an end time of the charging action, the start time being the first charging moment, and the end time being the second charging moment, and these two times are recorded as a set of charging moments under the charging signal. The charging information database includes each set of charging moments and the number of charges corresponding to each set of charging moments, which are received and stored by the VUC. The stored data set is the charging information database; S102. Calculate the charging duration of each group of the first and second charging times. Optionally, for any user's vehicle charging behavior, the charging duration of the current charging behavior is calculated by subtracting the first charging time from the second charging time corresponding to the current group of charging times received by the VUC for the current charging behavior. S103. When it is determined that the charging duration of the current group is greater than or equal to the first preset duration, the number of charging times is set to be cumulatively incremented by 1 and stored in the charging information database. Optionally, since the effective charging duration is related to the battery capacity and charging power of the vehicle itself and the output power of the charging equipment, the first preset charging duration is different for each vehicle model. The first preset duration is the effective charging duration. The effective charging duration refers to the time during which the vehicle can provide sufficient power for the near-term driving after charging for this period of time. It is generally measured in terms of cruising range, i.e., after charging for the first preset duration, the vehicle can achieve a cruising range of 500 kilometers. When the VCU determines that the current charging duration is greater than or equal to the first preset duration for the current vehicle model, the number of charging times corresponding to the most recent previous charging behavior stored in the charging information database is called up, and 1 is accumulated based on the number of charging times. The number of charging times stored in the charging information database is also updated to serve as a basis for revising the charging information database after the next charging behavior occurs. In a certain embodiment, the charging information database selects recorded data of four valid charging behaviors, namely, charging 1, charging 2, charging 3, and charging 4. Valid charging means that the charging duration is greater than or equal to the first preset duration T. The first charging moments corresponding to these four charging behaviors are t1, t2, t3, and t4, respectively, and the second charging moments corresponding to these four charging behaviors are t5, t6, t7, and t8, respectively. The corresponding relationship between the charging duration and the number of charging times for each group of charging moments is shown in Table 1: Table 1

[0021] S104. When it is determined that the number of charging times is greater than or equal to the preset number of charging times, a first prompt message is output, and the first prompt message is used to prompt the user to switch the driving mode; optionally, after the current number of charging times is updated and stored in the charging information database, it is compared with the preset number of charging times. The preset number of charging times can represent the user's charging habits and whether the current charging environment is convenient, including whether the charging infrastructure near the living environment is sufficient, etc. When the number of charging times is greater than or equal to the preset number of charging times, it means that the user has a high charging initiative, or the current charging environment is convenient, and the charging infrastructure in the working environment and the living environment is sufficient. When the number of charging times is less than the preset number of charging times, it means that the user has a weak charging initiative, or the current environment is inconvenient for charging, and the charging infrastructure is scarce. After comparison, the VCU judges When the current cumulative number of charging times is greater than or equal to the preset number of charging times, the first prompt information is output to the in-vehicle infotainment system (IVI). After the IVI receives the first prompt information output by the VCU, the IVI sends a signal to the instrument (IC). The IC has a dialog box for displaying prompt information. The dialog box displays two lines of text. The first line of text is a prompt area, displaying the text "It is recommended to switch the fuel mode to the automatic range extension mode", and the second line of text is a selection area, displaying the text "Yes or No". The user can control the dialog box on the IVI. At this time, the driver can follow the vehicle's real-time driving conditions through the prompt information to select a more suitable driving mode at the moment, switch from the fuel priority mode to the automatic range extension mode, improve economy, be more friendly to economically sensitive users, reduce unnecessary exhaust emissions, and protect the ecological environment.

[0022] Furthermore, after the first prompt information is output, the following step is further included: switching the driving mode in response to the input of the first confirmation information; the first confirmation information indicates acceptance of the first prompt information; optionally, when the IC displays a dialog box for the prompt information, if the user selects "Yes" in the selection area, it indicates that the user accepts the first prompt information, and the first confirmation information indicates acceptance of the first prompt information. At this time, the VCU controls the entire vehicle to switch the current driving mode from the fuel priority mode to the automatic range extension mode in response to the first confirmation information; Furthermore, in response to the input first confirmation information, after switching the driving mode, the following steps are also included: after switching the driving mode, the number of charging times corresponding to the second charging moment most recently before switching the driving mode is set to zero, and the charging information database is corrected; optionally, when the number of charging times corresponding to this charging behavior is just greater than or equal to the preset number of charging times, the driving mode is switched. After switching the driving mode, the VCU will set the number of charging times corresponding to this charging behavior stored in the charging information database to zero, and when the next charging behavior occurs, it is determined whether the charging duration of this charging behavior satisfies the condition of being greater than or equal to the first preset duration. If so, the number of charging times in the charging information database is 1.

[0023] Furthermore, after outputting the first prompt message, the following steps are also included: maintaining the current driving mode in response to the input second confirmation message; the second confirmation message is to cancel the first prompt message; optionally, when the IC displays the dialog box of the prompt message, the user selects "No" in the selection area, which means that the user rejects the first prompt message, and the second confirmation message is to reject the first prompt message. At this time, after responding to the second confirmation message, the VCU controls the entire vehicle to maintain the current driving mode, the fuel priority mode, unchanged.

[0024] Furthermore, after outputting the first prompt information, the following steps are also included: if the first confirmation information or the second confirmation information is not received within the second preset time period, the current driving mode is maintained; optionally, the VCU responds to the prompt signal, and the prompt signal includes a start prompt signal and a stop prompt signal, and stores the first prompt time of receiving the start prompt signal and the second prompt time of receiving the stop prompt signal, and the second prompt time is subtracted from the first prompt time to calculate the current waiting time for the prompt information. When the waiting time is greater than or equal to the second preset time period, it indicates that the user has not made a selection within the second preset time period. At this time, the VCU responds and controls the entire vehicle to maintain the current driving mode, the fuel priority mode, unchanged.

[0025] Furthermore, after the step of storing the charging time when the charging signal is received in response to the charging signal, the method further includes the following steps: S600. Calling a vehicle operation database, the vehicle operation database including: a set of the first charging time and the second charging time corresponding to each charging signal, and the mileage corresponding to the charging signal; optionally, the mileage is the mileage of the vehicle between the first charging time and the second charging time, obtained by subtracting the mileage at the first charging time from the mileage at the second charging time; S601. Determine that the interval between the second charging moment adjacent to the first charging moment is greater than or equal to the third preset time length, and the mileage is greater than or equal to the preset mileage, assign the charging times to zero, and correct the charging information database; optionally, in a certain specific scenario, when the interval between two charging behaviors is long, it means that the user's current charging enthusiasm is not high or the current charging environment is not friendly. At this time, if the vehicle enters the automatic range extension mode and needs to consume power during driving, then charging behavior is required to replenish the power of the vehicle, but the current scenario is not convenient for charging behavior. It is not recommended to use the automatic range extension mode in the current scenario. Therefore, this situation is not used as a basis for determining whether to issue a reminder to switch driving modes. According to the data, it is necessary to exclude this driving scenario and set the number of charging times in the charging information database to zero; however, considering that there is also a situation where the user has no need to use the vehicle for a long time due to some special reasons and parks the vehicle at a fixed location for a long time, resulting in a long interval between two charging behaviors, therefore, on the basis of judging that the time interval between two charging times is greater than or equal to the third preset time length, it is also necessary to add the limiting condition of the mileage to exclude this situation. When both the charging interval and the mileage limiting conditions are met at the same time, it means that the user's current demand for the vehicle is normal, but the frequency of charging behavior is low, indicating that the current environment is not conducive to charging behavior, and it is not recommended to switch to the current driving mode, so the number of charging times is set to zero.

[0026] Furthermore, after the charging time of the charging signal is stored in response to the charging signal, the following steps are also included: S700. Calling a vehicle operation database, the vehicle operation database includes: a set of the first charging time and the second charging time corresponding to each charging signal, and the fuel consumption corresponding to the charging signal; S701. When it is determined that the interval between the second charging moment adjacent to the first charging moment is greater than or equal to the third preset time length, and the fuel consumption is greater than or equal to the preset fuel consumption, the number of charging times is assigned to zero, and the charging information database is corrected; optionally, the fuel consumption is the fuel consumption of the vehicle between the first charging moment and the second charging moment, which is obtained by subtracting the remaining fuel at the first charging moment from the remaining fuel at the second charging moment. This zeroing is achieved by adding the fuel consumption indicator to exclude the situation where the interval between two charging behaviors is long due to the user parking the vehicle at a fixed location for a long time without using the vehicle for some special reason.

[0027] Example 2 The same points as those in Example 1 are not described in detail. The difference lies in that a vehicle operation database is called, and the vehicle operation database includes: a set of the first charging time and the second charging time corresponding to each charging signal, and the mileage and fuel consumption corresponding to the charging signal; When it is determined that the interval between the second charging time adjacent to the first charging time is greater than or equal to the third preset time length, the mileage is greater than or equal to the preset mileage, and the fuel consumption is greater than or equal to the preset fuel consumption, the number of charging times is set to zero and the charging information database is corrected.

[0028] Example 3 Based on embodiment 1, the driving mode determination device further includes: a first receiving module, the first receiving module being configured to respond to a charging signal, the charging signal including a start charging signal and a stop charging signal, and store a first charging time of the start charging signal and a second charging time of the stop charging signal; optionally, when the BMS collects a trigger signal generated by the vehicle charging socket and the charging terminal being in contact with each other and a current signal indicating current flowing into the vehicle, the first receiving module receives the start charging signal; and when the vehicle charging socket and the charging terminal are separated from each other, the stop charging signal is generated, and the first receiving module receives the stop charging signal; a calling module configured to call a charging information database to obtain a charging count corresponding to a second charging time adjacent to the first charging time; the charging information database comprising: a set of the first charging time and the second charging time corresponding to each charging signal, and a charging count corresponding to the set; optionally, the query module may retrieve and query required charging information from the charging information database; a calculation module configured to calculate a charging time of each group based on the first charging time and the second charging time; optionally, the calculation module performs a subtraction operation on the second charging time from the first charging time; a first judgment module, configured to, when determining that the charging time of the group is greater than or equal to a first preset time, set the cumulative number of charging times to be incremented by 1 and store the result in a charging information database; optionally, compare the charging time stored in the charging information database with the first preset time and determine whether the set requirement is met; if so, add 1 to the cumulative number of charging times and modify the charging information database; The second judgment module is configured to output a first prompt message when it is determined that the number of charging times is greater than or equal to a preset number of charging times, and the first prompt message is used to prompt the user to switch the driving mode; optionally, the second judgment module compares the number of charging times stored in the charging information database with the preset number of charging times and determines whether it is necessary to output the first prompt message, and the second judgment module outputs the first prompt message to the IVI when the output conditions are met.
