[0002] At present, the control strategy of extended-range electric vehicles is usually: when the battery is high, it drives in pure electric mode, and when the battery is low, it drives in extended-range mode; and the extended-range mode can set the corresponding balance power according to different driving modes (such as energy saving, sports, etc.), and different balance power corresponds to different power and economy.

[0037] 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.

[0038] 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.

[0039] Figure 1 This is a flow chart of a method for optimizing the driving mode of an extended-range electric vehicle provided in an embodiment of the present application. Figure 1 The driving mode optimization method of the extended-range electric vehicle specifically includes:

[0040] S110: Obtain navigation information, and determine the existence of a high-energy consumption working condition based on the navigation information.

[0041] Among them, the navigation information is the path information from the current location to the destination location set by the user, and may include road information along the path information, etc. High-energy consumption conditions are conditions with high energy consumption during driving, including at least one of high-speed conditions and long uphill conditions. High-speed conditions mean that the road requires the minimum vehicle speed to reach a preset speed, such as 100km / h. Long uphill conditions mean continuous uphill (or downhill), the length of which exceeds the preset length, such as 4km. The existence status of high-energy consumption conditions is used to describe whether there are high-energy consumption conditions in the upcoming journey, and the existence status of high-energy consumption conditions includes existence or non-existence.

[0042] Specifically, the user can set the navigation destination according to driving needs, and then plan and obtain navigation information. In addition, the navigation information can be further analyzed for operating conditions along the way to determine whether it includes high-speed conditions and / or long uphill conditions. If at least one of the high-speed conditions and long uphill conditions is included, the existence status of the high-energy consumption condition is determined to be present; if neither the high-speed condition nor the long uphill condition is included, the existence status of the high-energy consumption condition is determined to be non-existent.

[0043] Based on the above example, the existence of high energy consumption conditions can be determined based on navigation information in the following ways:

[0044] Determining road information corresponding to the navigation path according to the navigation path corresponding to the navigation information;

[0045] If the road information includes an expressway and / or a long uphill road, determining that the high energy consumption operating condition exists is true;

[0046] If the road information does not include an expressway and a long uphill road, it is determined that the existence state of the high energy consumption operating condition is non-existent.

[0047] The navigation route is the path information from the current location to the destination. It is understood that the navigation information may include multiple routes to be selected, with the user selecting the route to be selected as the navigation route. Road information is used to describe various road-related information in the navigation route, such as road type, altitude, length, and road name. In this embodiment, it primarily includes road type, such as expressways and long uphill roads.

[0048] Specifically, after determining the navigation information, one or more routes to be selected can be displayed for user selection. The user can select the route they deem appropriate for subsequent travel based on their needs. The route selected by the user is then determined as the navigation route. The navigation route is then analyzed to obtain road information covered by the navigation route, and a determination is made as to whether the road information includes expressways and long uphill roads. Since expressways and long uphill roads correspond to high-energy-consuming operating conditions, the presence of high-energy-consuming operating conditions can be determined based on the presence of expressways and long uphill roads. The specific process will not be described in detail here.

[0049] It should be noted that if the high-energy consumption operating condition exists, it means that the energy consumption when driving under this operating condition will be higher than when driving under normal energy consumption conditions, which will cause the pure electric mode to be unable to support driving and easily cause the problem of insufficient power.

[0050] S120: Determine the vehicle driving mode based on the existence of the high-energy consumption operating condition, the remaining pure electric mileage, the total pure electric mileage, and the total navigation mileage.

[0051] The remaining pure electric range is the distance the vehicle can travel in pure electric mode with the remaining battery charge. The total pure electric range is the distance the vehicle can travel in pure electric mode with a full charge. The total navigation range is the mileage information included in the navigation information, which describes the mileage of the navigation route. Vehicle driving modes include pure electric mode and extended range mode.

[0052] Specifically, by comparing the remaining pure electric range with the total navigation range, it can be determined whether pure electric mode can support driving along the route specified in the current navigation information. If so, the vehicle's driving mode is determined to be pure electric mode; if not, the vehicle's driving mode is determined to be extended-range mode. Furthermore, based on the presence of high-energy consumption conditions, the total pure electric range, and the total navigation range, it can be further determined whether the current default extended-range mode (extended-range mode for flat roads, short distances, and medium-to-low speed driving) can support driving along the route specified in the navigation information, and whether the balance charge in the extended-range mode needs to be further adjusted to update the extended-range mode to facilitate adaptation to the driving conditions.

[0053] Based on the above example, we can first compare the remaining pure electric range and the total navigation range to distinguish between setting pure electric mode and extended range mode. Specifically, we can use the following method to determine the vehicle driving mode based on the presence of high-energy consumption conditions, the remaining pure electric range, the total pure electric range, and the total navigation range:

[0054] If the remaining pure electric mileage is greater than or equal to the total navigation mileage, the vehicle driving mode is determined to be pure electric mode;

[0055] If the remaining pure electric mileage is less than the total navigation mileage, the vehicle driving mode is determined based on the total navigation mileage, the total pure electric mileage and the existence of high-energy consumption conditions.

[0056] Specifically, if the remaining pure electric range is greater than or equal to the total navigation range, the vehicle is determined to be able to complete the remaining route in the navigation information using the current remaining power, and therefore the vehicle's driving mode is determined to be pure electric mode. Otherwise, the vehicle's current remaining power cannot support the route in the subsequent navigation information, and therefore the vehicle's driving mode can be determined to be extended-range mode. Based on the total navigation range, the total pure electric range, and the presence of high-energy consumption operating conditions, it is determined whether the default extended-range mode (the extended-range mode for flat roads, short distances, and medium-to-low speed driving) can support the vehicle's travel along the route in the navigation information, and whether it is necessary to adjust the balance power of the range extender in the specific extended-range mode.

[0057] Based on the above example, the following situations are analyzed separately to determine the vehicle driving mode:

[0058] Case 1: If the total navigation mileage is less than the total pure electric mileage and the high-energy consumption operating condition does not exist, the vehicle driving mode is determined to be the extended-range mode with the default power as the balance power.

[0059] The default charge level is the pre-calibrated charge level for the extended-range mode. This is the battery charge level typically used in extended-range mode, specifically when driving on flat roads, short distances, and at low to medium speeds. The balanced charge level refers to the battery charge level when the range extender is turned on, i.e., the state of charge of the power battery.

[0060] It should be noted that in this embodiment, the total mileage that can be traveled in pure electric mode with a full charge, i.e., the pure electric total mileage, serves as the demarcation between long-distance driving conditions and non-long-distance driving conditions. It can be understood that if the navigation route cannot be completed even with a full charge and pure electric mode, the long-distance driving condition is considered to exist.

[0061] Specifically, if the total navigation mileage is less than the total electric mileage, it is assumed that there are no long-distance driving conditions. If the high-energy consumption conditions are not present, it is assumed that there are no high-energy consumption conditions. Based on this, since the entire driving cannot be completed using pure electric mode, the vehicle driving mode is determined to be extended-range mode, and the balance power in extended-range mode is set to the default power level. No further adjustment of the balance power is required.

[0062] Case 2: If the total navigation mileage is less than the total pure electric mileage and the high energy consumption condition exists, or the total navigation mileage is not less than the total pure electric mileage and the high energy consumption condition does not exist, the vehicle driving mode is determined to be the extended-range mode with the first power as the balance power.

[0063] Among them, the first power is the power pre-calibrated in the extended-range mode, which is the battery power calibrated under high-energy consumption conditions or long-distance conditions. The first power is greater than the default power.

[0064] Specifically, if the total navigation mileage is less than the total electric mileage and the high-energy-consumption operating condition is present, it indicates that high-energy-consumption operating conditions are currently present but long-distance operating conditions are not. If the total navigation mileage is not less than the total electric mileage and the high-energy-consumption operating condition is absent, it indicates that high-energy-consumption operating conditions are not currently present but long-distance operating conditions are present. This indicates that the balance charge needs to be increased to maintain a high battery charge to improve high-speed driving dynamics and fuel economy. Based on this, the vehicle's driving mode is determined to be extended-range mode, with the first balance charge as the balance charge.

[0065] Based on the above example, after determining that the vehicle driving mode is the extended-range mode with the first power level as the balance power level, it is also possible to switch to pure electric driving when approaching the destination to optimize the fuel economy of the entire journey. Specifically:

[0066] When driving in the extended-range mode with the first power level as the balance power level, obtaining the remaining pure electric mileage and the remaining total mileage;

[0067] If the remaining pure electric mileage is greater than the remaining total mileage, the vehicle driving mode is determined to be pure electric mode.

[0068] The remaining total mileage is the remaining mileage required to be traveled according to the navigation information during the driving process.

[0069] Specifically, when driving in extended-range mode with the first battery level as the balance charge, the remaining pure electric range and the remaining total range can be obtained in real time or periodically to further determine whether the remaining battery level can support driving the remaining route specified in the navigation information. If the remaining pure electric range is greater than the remaining total range, it can be determined that the remaining battery level can support the vehicle to complete the remaining route specified in the navigation information. Therefore, the vehicle driving mode can be switched to pure electric mode to improve fuel economy. If the remaining pure electric range is not greater than the remaining total range, the current extended-range mode with the first battery level as the balance charge is maintained.

[0070] Case 3: If the total navigation mileage is not less than the total pure electric mileage and the high energy consumption operating condition exists, the vehicle driving mode is determined to be the extended-range mode with the second power as the balance power.

[0071] Among them, the second power is the power pre-calibrated in the extended-range mode, and is the battery power calibrated under high-energy consumption conditions and long-distance conditions. The second power is greater than the first power.

[0072] Specifically, if the total navigation mileage is not less than the total electric mileage and the high-energy consumption condition is present, it indicates that both high-energy consumption and long-distance driving conditions are present. Therefore, it is necessary to further increase the balance charge, based on the first balance charge, to maintain a high battery charge. This improves high-speed driving performance and fuel economy under long-distance and high-energy consumption conditions. Based on this, the vehicle's driving mode is determined to be extended-range mode, with the second balance charge as the balance charge.

[0073] Based on the above example, after determining that the vehicle driving mode is the extended-range mode with the second power level as the balance power level, it is also possible to switch to pure electric driving when approaching the destination to optimize the fuel economy of the entire journey. Specifically:

[0074] When driving in the extended range mode with the second power level as the balance power level, obtain the remaining pure electric mileage and the remaining total mileage;

[0075] If the remaining pure electric mileage is greater than the remaining total mileage, the vehicle driving mode is determined to be pure electric mode.

[0076] Specifically, when driving in extended-range mode with the second charge as the balance charge, the remaining pure electric range and the remaining total range can be obtained in real time or periodically to further determine whether the remaining charge can support driving the remaining route specified in the navigation information. If the remaining pure electric range is greater than the remaining total range, it can be determined that the remaining charge can support the vehicle to complete the remaining route specified in the navigation information. Therefore, the vehicle driving mode can be switched to pure electric mode to improve fuel economy. If the remaining pure electric range is not greater than the remaining total range, the current extended-range mode with the second charge as the balance charge is maintained.

[0077] It should be noted that if there is a long-distance driving condition, the extended-range electric vehicle may have problems with poor power and fuel economy due to low battery power. Therefore, the above method is used to adjust the balance of power to improve vehicle power and fuel economy.

[0078] The driving mode optimization method, electronic device and medium of the extended-range electric vehicle provided in the embodiments of the present application obtain navigation information to determine the existence of high-energy consumption conditions based on the navigation information, and then analyze the existence of high-energy consumption conditions, the remaining pure electric mileage, the total pure electric mileage and the total navigation mileage to determine whether the pure electric mode can support driving and meet the power requirements. Based on this, the vehicle driving mode is determined to be pure electric mode or extended-range mode, thereby achieving the effect of improving the fuel economy and power of the extended-range electric vehicle.

[0079] Figure 2 This is a flow chart of another method for optimizing the driving mode of an extended-range electric vehicle provided by an embodiment of the present application. When the user uses the vehicle computer to start navigation, it is determined based on the navigation information whether there is a need for long-distance driving, whether the driving route has high-speed conditions, and whether the driving route has long uphill slopes. If there are long-distance driving, high-speed driving, long uphill slopes and other working conditions, it is necessary to increase the system balance power to keep the battery at a high power level, thereby improving the power and fuel economy of high-speed driving. When the destination is about to be reached, switch to pure electric driving to optimize the fuel economy of the entire journey. See Figure 2 The driving mode optimization method of the extended-range electric vehicle specifically includes:

[0080] 1. If the remaining pure electric mileage is greater than or equal to the total navigation mileage, the vehicle will be controlled to travel in pure electric mode.

[0081] 2. If the remaining pure electric range is less than the total navigation range, the total navigation range is less than the total pure electric range, and there is no need for high-speed driving and / or long uphill driving, the vehicle will be controlled to travel in Extended Range Mode 1. The balance charge in Extended Range Mode 1 is the default charge.

[0082] 3. If the remaining electric range is less than the total navigation range, the total navigation range is less than the total electric range, and there is a need for high-speed driving and / or long uphill driving, or if the total navigation range is not less than the total electric range, and there is no need for high-speed driving and / or long uphill driving, the balance power level is set to the first power level:

[0083] ① If the remaining pure electric range is less than or equal to the remaining total range, the vehicle is controlled to travel in extended range mode 2. The balance power in extended range mode 2 is the first power.

[0084] ② If the remaining pure electric mileage is greater than the remaining total mileage, control the vehicle to travel in pure electric mode.

[0085] 4. If the remaining pure electric range is less than the total navigation range, the total navigation range is not less than the total pure electric range, and there is a need for high-speed driving and / or long uphill driving, set the balance power level to the second power level:

[0086] ① If the remaining pure electric range is less than or equal to the remaining total range, the vehicle is controlled to travel in extended range mode 3. The balance power in extended range mode 3 is the second power.

[0087] ② If the remaining pure electric mileage is greater than the remaining total mileage, control the vehicle to travel in pure electric mode.

[0088] The driving mode optimization method for an extended-range electric vehicle provided in an embodiment of the present application determines the user's vehicle usage scenarios in the next period of time based on the user's navigation information. If there are long-distance, high-speed, long uphill driving scenarios, the start-up strategy of the range extender is dynamically adjusted to keep the battery at a high power level. For the battery, a higher power level has the characteristics of smaller internal resistance, higher voltage, and higher battery discharge power. These characteristics can improve the fuel economy and power of the extended-range electric vehicle and enhance the driving experience.
