Description

Technical Field

[0001] The present application relates to the technical field of driving modes of range-extended electric vehicles, and particularly to a method, device, terminal device and storage medium for determining a driving mode. Background Art

[0002] In recent years, range-extended electric vehicles have been widely concerned and researched in China due to their advantages such as low fuel consumption, quiet driving, low environmental pollution, and low basic investment. In the process of R & D and design, different usage characteristics and usage scenarios of the vehicle are mainly considered comprehensively, especially in-depth research and discussion on the state-of-charge characteristics of the battery, the matching of the drive motor and the battery, and the vehicle control strategy. In the research on the vehicle control strategy, how to select the most suitable driving mode for the current usage scenario has become a hot research topic. The driving modes of range-extended electric vehicles are generally divided into pure-electric priority mode, automatic range-extended mode, and fuel priority mode;

[0003] When the power battery has sufficient power, a range-extended electric vehicle generally operates in the pure-electric priority mode. At this time, the power source almost entirely comes from the power battery, and zero fuel consumption and zero emissions can be achieved. However, the battery power gradually decreases as the driving mileage increases. If the current driving environment cannot replenish the battery power in time, when the power cannot meet the maximum power demand of the vehicle, continuous low-power driving will interfere with the vehicle's power performance and reduce the user's driving and riding experience.

[0034] The following further elaborates on this application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the related invention and not for limiting the invention. Additionally, it should be noted that for the sake of convenience in description, only the parts related to the invention are shown in the drawings.

[0035] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will elaborate on this application in detail with reference to the drawings and embodiments.

[0036] Embodiment 1

[0037] As mentioned in the background art, in response to the problems in the prior art, this application proposes an intelligent driving mode prediction method, including the following steps:

[0038] S100. In response to the high-voltage power-on signal of the vehicle, store the power-on moment when receiving the vehicle start signal; optionally, electric vehicles generally have two power systems, one is a low-voltage system and the other is a high-voltage system. For range-extended electric vehicles, the high-voltage power-on signal is the signal for the vehicle to power on within the high-voltage system. When the user inserts the key to power on, it indicates the generation of the high-voltage power-on signal, and when the user removes the key to power off, it indicates the generation of the high-voltage power-off signal. The entire driving cycle of the vehicle is from the response to the high-voltage power-on signal to the high-voltage power-off signal, and the moment of high-voltage power-on of the vehicle is the power-on moment;

[0039] S101. Obtain the real-time battery power and the real-time driving speed; optionally, the battery is an important power source of the range-extended electric vehicle and one of the most core components of the range-extended electric vehicle. Therefore, the real-time battery power of the vehicle is directly related to the vehicle's cruising range. The real-time remaining battery power can be obtained from the battery management system (BMS), and the real-time driving speed is collected by the vehicle speed sensor and transmitted to the vehicle control unit (VCU) in real time;

[0040] S102. Call the driving information database to obtain the number of driving times corresponding to the previous power-on time adjacent to the current power-on time; the driving information database includes: the power-on time and the corresponding number of driving times; optionally, the high-voltage power-on signal for each vehicle start by the user will be received and stored by the VCU. Each time the vehicle is started, the number of driving times corresponding to the previous adjacent power-on time in the driving information database will be retrieved. On this basis, the power-on time corresponding to each driving cycle and the number of driving times corresponding to the power-on time will be recorded in sequence. Each set of recorded data is the driving information database;

[0041] S103. When it is determined that the real-time battery power is less than or equal to the preset battery power and the real-time driving speed is greater than or equal to the preset driving speed, set the cumulative number of driving times to be incremented by 1 and store it in the driving information database; optionally, the preset battery power is related to factors such as vehicle model, road conditions, driving speed, and weather temperature. Considering the factor that the power consumption speed of the power battery will increase when the electric vehicle is driving at a relatively high speed and the weather temperature is relatively low, the preset battery power is the battery power value that can meet the driving requirement of the vehicle to have a cruising range of 300 kilometers under normal conditions. When the remaining battery power of the vehicle is less than or equal to the preset battery power, it indicates that the current battery power of the vehicle is low. When the real-time driving speed is greater than or equal to the preset driving speed, it indicates that the user has a current driving requirement. If the user has a high-power requirement during the current driving process, when the real-time battery power of the vehicle is less than or equal to the preset battery power, the power output of the vehicle will be limited. The high-power driving requirement of the user this time will be restricted due to low battery power. At this time, the number of driving times corresponding to the current power-on time needs to be incremented by 1 based on the number of driving times corresponding to the previous adjacent power-on time in the driving information database, and at the same time, the information in the driving information database is updated for reference in the number of driving times corresponding to the power-on time of the next driving behavior. During an entire driving cycle, the real-time battery power gradually decreases, and the remaining power becomes lower and lower. When at a certain moment during the driving process, it just meets the condition that the battery power is less than or equal to the preset battery power and the real-time driving speed is greater than or equal to the preset driving speed, the cumulative number of driving times is incremented by 1, but only once during an entire driving cycle, without repeated accumulation;

[0042] In one embodiment, the driving information database selects the driving times at the five power-on moments, namely power-on 1, power-on 2, power-on 3, power-on 4, and power-on 5. The driving at these five power-on moments all satisfies that the real-time battery power is less than or equal to the preset battery power, and the real-time driving speed is greater than or equal to the preset driving speed. The corresponding moments for starting these five vehicles are T1, T2, T3, T4, and T5. The relationship between the power-on moment and the corresponding driving times is shown in Table 1 as follows:

[0043] Table 1

[0044] High-voltage power-on Power-on 1 Power-on 2 Power-on 3 Power-on 4 Power-on 5 Moment T1 T2 T3 T4 T5 Number of driving times n n+1 n+2 n+3 n+4

[0045] S104. When it is determined that the driving times are greater than or equal to the first preset driving times, output a first prompt message, where the first prompt message is used to prompt the user to switch the driving mode; optionally, when the driving times accumulated at a certain moment in a certain driving cycle are exactly greater than or equal to the first preset driving times, immediately output the first prompt message to the in-vehicle infotainment system (IVI). The real-time battery power of the vehicle is too low, which will limit the output power. When the user has a high-power driving demand during this driving cycle, the limitation will greatly affect the user's driving and riding experience. The first preset driving times are the accumulated low-power driving times of the vehicle in the pure-electric priority mode. When the driving times are greater than or equal to the first preset driving times, it means that the user has driven at a lower power for a relatively large number of times, and the driving demand may be limited multiple times. When the vehicle control unit (VCU) receives and determines that the currently accumulated driving times are greater than or equal to the first preset driving times, it outputs the first prompt message to the IVI. After receiving the first prompt message output by the VCU, the IVI sends a signal to the instrument cluster (IC). The IC has a dialog box for displaying prompt messages. The dialog box displays two lines of text. The first line of text is the prompt area, which displays the text "It is recommended to switch the pure-electric mode to the automatic range-extending mode", and the second line of text is the selection area, which displays the text "Yes or No". The user can perform control operations on the dialog box on the IVI. At this time, the driver can select a more suitable driving mode according to the real-time driving conditions of the vehicle through the prompt message, switch from the pure-electric priority mode to the automatic range-extending mode, and timely meet the maximum power demand of the vehicle to improve the power performance of the vehicle and the user's driving and riding experience.

[0046] Further, after outputting the first prompt message, the following steps are further included:

[0047] In response to the input of the first confirmation information, switch the driving mode; the first confirmation information is accepting the first prompt message; optionally, when the IC displays a dialog box with a prompt message, if the user selects "Yes" in the selection area, it means the user accepts the first prompt message, and the first confirmation information is accepting the first prompt message. At this time, after the VCU responds to the first confirmation information, it controls the whole vehicle to switch the current driving mode, the pure-electric priority mode, to the automatic range-extending mode;

[0048] Or, in response to the input of the second confirmation information, maintain the current driving mode; the second confirmation information is canceling the first prompt message; optionally, when the IC displays a dialog box with a prompt message, if the user selects "No" in the selection area, it means the user rejects the first prompt message, and the second confirmation information is rejecting the first prompt message. At this time, after the VCU responds to the second confirmation information, it maintains the current driving mode of the whole vehicle, the pure-electric priority mode, unchanged.

[0049] Further, after switching the driving mode, the following steps are also included: set the driving times corresponding to the vehicle power-on moment closest to before switching the driving mode to zero, and correct the driving information database; optionally, after switching the driving mode, the VCU will set the driving times stored in the driving information database corresponding to the current power-on moment to zero, and continue the above steps when the vehicle undergoes high-voltage power-on next time.

[0050] Further, after outputting the first prompt message, the following steps are also included: if the first confirmation information or the second confirmation information is not received within the preset waiting duration, maintain the current driving mode; optionally, the VCU responds to the prompt signal, where the prompt signal includes a start prompt signal and a stop prompt signal, stores the first prompt moment when receiving the start prompt signal, and the second prompt moment of the stop prompt signal. The waiting duration of the prompt message can be calculated by subtracting the first prompt moment from the second prompt moment. When the waiting duration is greater than or equal to the preset waiting duration, it means the user has not made a selection within the time of the preset waiting duration. At this time, the VCU responds and controls the whole vehicle to maintain the current driving mode, the pure-electric priority mode, unchanged.

[0051] Further, after obtaining the real-time battery power, the following steps are also included: if the obtained battery power is greater than the preset battery power, set the driving times to zero and correct the driving information database; optionally, when the battery power is greater than the preset battery power, it means the vehicle's battery power can meet the requirements of the cruising range and can provide sufficient power sources for the vehicle, and there will be no low-battery driving in the pure-electric priority mode in the near future. Therefore, the driving times are set to zero and the driving information database is corrected. When there is low-battery driving in the pure-electric priority mode next time, the accumulation of the driving times will be carried out again.

[0052] Further, after obtaining the real-time battery power and the real-time driving speed, the following steps are further included. When the battery power is less than the preset battery power and the real-time driving speed is less than the preset driving speed, the number of driving times remains unchanged; Optionally, when the battery power is less than the preset battery power and the real-time driving speed is less than the preset driving speed, it indicates that the vehicle's current driving belongs to the situation of low battery power. However, the required driving speed being less than the preset driving speed indicates that there is no excessive power demand at present, and the current battery power can meet the user's current driving needs. Therefore, this driving cycle is not regarded as a low-battery driving in the pure electric driving mode, so the previous number of driving times remains unchanged and is not accumulated.

[0053] Further, after calling the driving information database to obtain the number of driving times corresponding to the previous power-on moment adjacent to the current power-on moment, and before determining that the number of driving times is greater than or equal to the first preset number of driving times and outputting the first prompt message, the following steps are further included:

[0054] S800. When it is determined that the real-time battery power is greater than the preset battery power, in response to the high-voltage power-off signal of the vehicle, store the power-off moment of the high-voltage power-off; Optionally, when the user pulls out the key to cut off the power, it means that the high-voltage power-off signal is generated, and the power-off moment is recorded at the moment when the high-voltage power-off signal is generated;

[0055] S801. Obtain the average temperature between the power-on moment and the power-off moment; Optionally, the temperature outside at the power-on moment is C1, and the temperature outside at the power-off moment is C2. The calculation formula for the average temperature between the power-on moment and the power-off moment is

[0056] S802. When it is determined that the average temperature is less than or equal to the preset ambient temperature and the real-time driving speed is greater than or equal to the preset driving speed, set the cumulative number of driving times to increase by 1 and store it in the driving information database; Optionally, within the range of 0 degrees to 25 degrees, for every 1-degree decrease in temperature, the battery capacity of an electric vehicle decreases by about 1%. The lower the temperature, the less likely the electrolyte of the storage battery is to diffuse, and the slower the chemical reaction speed of the two active substances will be, resulting in a decrease in the battery voltage. Therefore, if an electric vehicle in the pure electric priority driving mode travels too many times in a low-temperature environment, it will seriously affect the battery performance. The preset temperature is the common temperature in northern winter, which is minus 10 degrees Celsius. When the average temperature is less than or equal to the preset ambient temperature and the real-time driving speed is greater than or equal to the preset driving speed, it indicates that the electric vehicle is driving in a low-temperature environment and has a demand for outputting a large power. Therefore, it is prompted that the user switches the pure electric priority mode to the automatic range-extending mode to meet the user's driving power demand while protecting the battery life.

[0057] Embodiment 2

[0058] The same parts as those in Embodiment 1 will not be described in detail again. The differences are as follows:

[0059] In response to the vehicle driving signal, store the power-on time when the vehicle powers on at high voltage and the power-off time when the vehicle powers off at high voltage;

[0060] Obtain the real-time ambient temperature at each moment between the power-on time and the power-off time;

[0061] Call the scenario information database to obtain the number of driving times corresponding to the power-off time adjacent to the power-on time; the scenario information database includes: a set of the power-on time and the power-off time corresponding to each vehicle driving signal, and the number of driving times corresponding to this set;

[0062] Calculate the driving duration of this time based on the power-on time and the power-off time;

[0063] When it is determined that the driving duration of this time is greater than or equal to the preset driving duration and the real-time ambient temperature is less than or equal to the preset ambient temperature, set the cumulative number of driving times to be incremented by 1 and store it in the scenario information database;

[0064] When it is determined that the number of driving times is greater than or equal to the second preset number of driving times, output a first prompt message to the IVI, and the first prompt message is used to prompt the user to switch the driving mode;

[0065] In a certain embodiment, the scenario information database selects the recorded data in five driving scenarios, namely Scenario 1, Scenario 2, Scenario 3, Scenario 4, and Scenario 5. The high-voltage power-on time of the vehicle in each scenario is the first time, which are t1, t2, t3, t4, and t5 respectively. The high-voltage power-off time of the vehicle is the second time, which are t6, t7, t8, t9, and t10 respectively. The current driving temperature is K1, K2, K3, K4, and K5. If in these five driving scenarios, the driving duration is greater than or equal to the preset driving duration T and the real-time ambient temperature is less than or equal to the preset ambient temperature C, the corresponding relationship in the scenario information database is shown in Table 1:

[0066] Table 1

[0067]

[0068]

[0069] In a specific scenario, based on the intelligent reminder strategy of Embodiment 1, the real-time ambient temperature can also be collected. The reminder strategies of Embodiment 1 and Embodiment 2 are independent of each other and do not interfere with each other. Since the battery of a range-extended electric vehicle is one of the most core components, most batteries are the products of electrochemistry, and its performance is greatly related to the temperature. In a low-temperature environment, the performance of the battery is extremely damaged, and it will also extend the charging time of the electric vehicle. And the overly long charging time will seriously hinder the user's experience of the electric vehicle. Therefore, when the VCU receives a signal that the current driving duration is greater than or equal to the preset driving duration and the real-time ambient temperature is less than or equal to the preset ambient temperature, it indicates that the vehicle has been driving in a low-temperature condition for a long time, which has a great impact on the battery life and the battery output power. At this time, it is not recommended to continue using the current pure-electric priority mode. Therefore, the first prompt message is sent to prompt the user to switch the driving mode to protect the battery and improve the battery life.

[0071] Based on Embodiment 1, referring to Figure 2 , the driving mode determination device further includes:

[0074] A first judgment module, the first judgment module is configured to judge that when the real-time battery power is less than or equal to the preset battery power and the real-time driving speed is greater than or equal to the preset driving speed, set the cumulative number of driving times to be incremented by 1 and store it in the driving information database;

[0075] A second judgment module, configured to output a first prompt message for prompting a user to switch a driving mode when the number of driving times is greater than or equal to a first preset number of driving times; optionally, the second judgment module compares the number of driving times stored in the driving information database with the preset number of driving times and determines whether to output the first prompt message to an in-vehicle infotainment system (IVI), and when the requirement is met, the second judgment module outputs the first prompt message to remind the user to switch the current driving mode;

[0076] Further, it further includes a second receiving module, which is CAN communication-connected to the display module, and the second receiving module is configured to receive the first confirmation message or the second confirmation message; optionally, the second receiving module and the display module send and receive signals to each other through a controller area network ( CAN ) communication. The IVI display screen is a touch screen. When the user touches "Yes" in the dialog box, the second receiving module receives the first confirmation message. When the user touches "No" in the dialog box, the second receiving module receives the second confirmation message.
