[0030] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0031] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0032] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0033] In this application, "plurality" refers to two or more. "And / or" describes the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0034] Existing extended-range electric vehicles typically operate primarily on electricity, then burn gasoline to generate power when the vehicle's battery is low. In particular, when the vehicle is operating on slow roads and detects a low battery level, the range extender is forced to activate, causing it to generate power at low power, low efficiency, and high fuel consumption, making it impossible to properly control the range extender's power generation.

[0035] To this end, one aspect of this application provides a control method for a range extender based on navigation information. Figure 1 , Figure 1This is a flow chart of a control method for a range extender based on navigation information, as shown in an exemplary embodiment of the present application. The control method includes at least S110 to S130, which are described in detail as follows:

[0036] S110: Calculating the total power consumption required for the vehicle to travel to the destination based on the received navigation information of the destination and the vehicle's operating parameters; wherein the navigation information includes the driving time required for the vehicle to travel on various road sections with different speeds.

[0037] The navigation information for the destination is the information that the third-party platform feeds back to the execution end of this embodiment in response to the user's navigation request. For example, if a user plans to drive to location A, they will send a navigation request for location A to the third-party platform. The third-party platform will respond to the request and feed back the navigation information related to location A to the execution end of this embodiment.

[0038] Navigation information also includes the total length of the navigation route, the total navigation time, and the length of each speed segment. It also includes real-time information, such as speed limits, traffic lights, road clearance, and the remaining distance from the vehicle's current location to the destination. It also includes estimated information, such as the total travel time required to reach the destination.

[0039] Exemplarily, the length of the total navigation section and the total navigation time are obtained from the navigation information, and the power consumption of the vehicle's load electrical appliances and the consumption per unit mileage are obtained from the operating condition parameters; the total power consumption of the vehicle is calculated based on the length of the total navigation mileage and the consumption per unit mileage, and the total power consumption of the vehicle load is calculated based on the total navigation time and the power consumption of the load electrical appliances; the sum of the total power consumption of the vehicle's travel and the total power consumption of the vehicle load is the total power consumption required for the vehicle to reach the destination.

[0040] S120: If it is detected that the total power consumption is greater than or equal to the remaining power of the vehicle battery, the power consumption required for the vehicle to travel in each different speed section is calculated based on the driving time and operating condition parameters required for the vehicle to travel in each different speed section.

[0041] If it is detected that the total power consumption is greater than or equal to the remaining power of the vehicle battery, it means that the remaining power of the vehicle battery cannot meet the power demand of the vehicle in the navigation section, that is, it is necessary to control the range extender to generate electricity at a reasonable time and in a reasonable section to meet the driving needs of the vehicle.

[0042] If it is detected that the total power consumption is less than the remaining power of the vehicle battery, it indicates that the remaining power of the vehicle battery meets the power demand of the vehicle in the navigation section, that is, there is no need to control the range extender to perform power generation operations.

[0043] S130: Based on the relationship between the power consumption and the remaining power of the road section, a preset power generation strategy for controlling the range extender to perform power generation is determined, and the range extender is controlled to perform power generation according to the preset power generation strategy.

[0044] The power consumption of each road section is analyzed and processed, and the power consumption of a single section, or the sum of the power consumption of multiple sections, or the difference between the power consumption of multiple sections are compared with the remaining power. Based on the relationship between them, an adaptive preset power generation strategy is determined, and the range extender is controlled to perform power generation operations according to the preset power generation strategy.

[0045] This embodiment calculates in advance the road section power consumption required for the vehicle to travel in each road section with different vehicle speeds based on the received navigation information of the destination and the vehicle's operating parameters. Based on the relationship between the road section power consumption and the remaining power, the embodiment accurately determines a preset power generation strategy for controlling the range extender to perform power generation operations, thereby avoiding a situation where the range extender is forced to start. The range extender is reasonably controlled to perform power generation operations according to the preset power generation strategy, so that the power generation power of the range extender is within a reasonable range, thereby improving the power generation efficiency of the range extender during vehicle driving.

[0046] In an exemplary embodiment of the present application, a detailed description is given of how to determine a preset power generation strategy for controlling the range extender to perform power generation based on the relationship between the power consumption of the road section and the remaining power. For details, please refer to Figure 2 , Figure 2 is based on Figure 1 The exemplary embodiment shown is a flow chart of another method for controlling a range extender based on navigation information. The navigation information also includes the remaining road section from the vehicle's current location to the destination, and the remaining time required for the vehicle to travel from the current location to the destination. Figure 1 The illustrated S130 further includes S210 to S230, which are described in detail as follows:

[0047] S210: Calculate an estimated amount of power generated by the range extender during the remaining road section based on the remaining time and the preset power generation power of the range extender, and detect whether the total amount of power consumed in the designated road section is less than the remaining power.

[0048] It is worth noting that the remaining time and remaining distance are real-time parameters. The third-party platform obtains the current position of the vehicle in real time, analyzes and calculates it with the position of the destination to obtain the remaining distance, and estimates the remaining time required for the vehicle to travel from the current position to the destination.

[0049] The designated road sections in the present application are low-speed road sections and normal-speed road sections. In a preferred embodiment, the designated road sections are road sections from 0 to 90 kph.

[0050] There are multiple preset power generation capacities, such as P1, P2, P3, P4, etc. 10 When calculating the estimated power generation in this embodiment, the maximum preset power generation power is generally used, that is, P max .

[0051] Exemplarily, the remaining time and the preset power generation power are multiplied to obtain the estimated power generation; the power consumption of the low-speed section and the normal-speed section are summed to obtain the total power consumption of the specified section; the sum power is compared with the remaining power to detect whether it is less than the remaining power.

[0052] S220: If it is less than, performing a difference calculation on the total power consumption and the estimated power generation, and detecting whether the calculated difference is less than the remaining power.

[0053] For example, if the total power consumption is 120 units, the total power consumption of the designated road section is 100 units, and the remaining power is 110 units, that is, it is detected that the total power consumption of the designated road section is less than the remaining power, then the total power consumption of 120 units is subtracted from the estimated power generation calculated in the above S210 to obtain the difference between the two, and detect whether the difference is less than 110 units.

[0054] S230: If it is detected that the difference power is less than the remaining power, a preset power generation strategy for controlling the range extender to perform power generation at a constant preset power generation power is determined, and the range extender is controlled to perform power generation according to the preset power generation strategy.

[0055] For example, if the total power consumption is 120 units, the sum of the power consumption for the designated road sections is 100 units, the remaining power is 110 units, and the estimated power generation is 80 units, then the difference = 120 - 80 = 40. If the total power consumption is greater than the remaining power, the sum of the power consumption for the designated road sections is less than the remaining power, and the difference is less than the remaining power, the range extender is controlled to generate power at a constant preset power output and according to the preset power generation strategy. The preset power output is the most efficient preset power output.

[0056] If the pre-detection conditions of this embodiment are met, in a preferred embodiment, the preset power generation strategy is to control the range extender to not generate power on roads with speeds below 90 kph, and to generate power at a constant preset power level on roads with speeds above 90 kph. The preset power level is the most efficient preset power level. Generating power on highways by the range extender achieves high power efficiency and minimizes fuel consumption.

[0057] This embodiment provides a method for determining a preset power generation strategy. The total power consumed on a specified road section is compared with the remaining power, and the difference between the total power consumed and the estimated power generated is compared with the remaining power. If it is detected that the total power is less than the remaining power, and the difference is less than the remaining power, a preset power generation strategy is determined to control the range extender to generate power at a constant preset power level. This constant preset power level is within a reasonable range, thereby improving the power generation efficiency of the range extender during vehicle travel.

[0058] In an exemplary embodiment of the present application, another detection result of detecting whether the calculated difference power is less than the remaining power is described in detail. The corresponding preset power generation strategy is specifically referred to in Figure 3 , Figure 3 is based on Figure 2 The exemplary embodiment shown is a flow chart of another method for controlling a range extender based on navigation information. Figure 2 The illustrated S220 further includes S310, which is described in detail as follows:

[0059] S310: If it is detected that the difference in power is greater than or equal to the remaining power, a preset power generation strategy for controlling the range extender to perform power generation at a target power generation power is determined, and the range extender is controlled to perform power generation according to the preset power generation strategy; wherein the target power generation power is a parameter calculated based on the required power of the vehicle.

[0060] For example, if the total power consumption is 120 units, the sum of the power consumption on the designated road sections is 100 units, the remaining power is 110 units, and the estimated power generation is 5 units, then the difference = 120 - 5 = 115. If the total power consumption is greater than the remaining power, the sum of the power consumption on the designated road sections is less than the remaining power, and the difference is greater than the remaining power, the preset power generation strategy controls the range extender to generate power at the target power generation power. The target power generation power is not a preset parameter, but is primarily calculated based on the vehicle's required power.

[0061] If the pre-detection conditions of this embodiment are met, in a preferred embodiment, the preset power generation strategy is to disable the range extender on roads with speeds below 90 kph and to operate at a target power level on roads with speeds above 90 kph. The target power level is calculated based on the vehicle's required power. Generating the range extender on highways achieves high power generation efficiency and minimizes fuel consumption.

[0062] This embodiment provides another method for determining a preset power generation strategy. The total power consumed on a specified road section is compared with the remaining power, and the difference between the total power consumed and the estimated power generated is compared with the remaining power. If the total power is less than the remaining power, and the difference is greater than or equal to the remaining power, a preset power generation strategy is determined to control the range extender to generate power at a target power within a reasonable range, thereby improving the power generation efficiency of the range extender during vehicle travel.

[0063] In an exemplary embodiment of the present application, another detection result of detecting whether the total power consumption of all road sections is less than the remaining power is described in detail. The corresponding preset power generation strategy is specifically referred to in Figure 4 , Figure 4 is based on Figure 2 The exemplary embodiment shown is a flow chart of another method for controlling a range extender based on navigation information. The road section power consumption includes a first section power consumption corresponding to a first speed section and a second section power consumption corresponding to a second speed section; wherein the speed of the vehicle in the first speed section is less than the speed of the vehicle in the second speed section. The control method is as follows Figure 2 The illustrated S210 further includes S410 to S430, which are described in detail as follows:

[0064] S410: If it is greater than or equal to, summing the difference between the power consumption of the second section and the estimated power generation with the power consumption of the first section to obtain the summed power.

[0065] S420: Detect whether the power consumption of the first section and the total power are both less than the remaining power.

[0066] S430: If both are less than, determining a preset power generation strategy for controlling the range extender to generate power at a constant preset power in the second section and to generate power at a target power in sections other than the second section, and controlling the range extender to generate power according to the preset power generation strategy; wherein the target power is a parameter calculated based on the required power of the vehicle.

[0067] For example, in this embodiment, different speed sections include a first speed section (less than 30 kph), corresponding to a first section power consumption of 30 units; a second speed section (greater than 90 kph), corresponding to a second section power consumption of 10 units; and a third speed section (between 30 kph and 90 kph), corresponding to a third section power consumption of 20 units. In this embodiment, the designated sections are the first and third speed sections.

[0068] If the total power consumption is 120 units, the sum of the power consumption for the designated sections is 110 units, the remaining power is 100 units, and the estimated power generation is 5 units. If the total power consumption is greater than the remaining power, and the sum of the power consumption for the designated sections is greater than the remaining power, then for sections with speeds above 90 kph, the power consumption for the second section is subtracted from the estimated power generation, and then added to the power consumption for the first section. The resulting sum = 10 - 5 + 30 = 35. This means that both the power consumption for the first section and the sum are less than the remaining power. This indicates that the remaining power is less than the total power consumption, and the remaining power is only sufficient for the electric-only driving mode on low-speed sections. The default power generation strategy is to control the range extender to generate power at a constant default power level on sections with speeds above 90 kph and at a target power level on sections with speeds below 90 kph. The default power level is the most efficient default power level, and the target power level is a parameter calculated based on the vehicle's power demand.

[0069] This embodiment provides another preset power generation strategy. Through relevant testing, if the pre-test conditions of this embodiment are met, the preset power generation strategy is determined to control the range extender to generate power at a constant preset power level on the second road section and at a target power level on all other road sections. This embodiment adapts the power level to the different road sections, allowing the range extender to operate at different power levels in different sections, thereby improving the range extender's power generation efficiency during vehicle travel.

[0070] In an exemplary embodiment of the present application, another detection result of detecting whether the power consumption of the first section and the total power are both less than the remaining power is described in detail. The corresponding preset power generation strategy is specifically referred to in Figure 5 , Figure 5 is based on Figure 4 The exemplary embodiment shown is a flow chart of another method for controlling a range extender based on navigation information. Figure 4 The illustrated S420 further includes S510, which is described in detail as follows:

[0071] S510: If it is detected that the power consumption of the first section is greater than or equal to the remaining power, or the total power is greater than or equal to the remaining power, a preset power generation strategy for controlling the range extender to perform power generation operation at a target power generation power is determined, and the range extender is controlled to perform power generation operation according to the preset power generation strategy.

[0072] If it is detected that the power consumption of the first section is greater than or equal to the remaining power, there is no need to detect whether the sum of the power values ​​is greater than or equal to the remaining power, and the preset power generation strategy for controlling the range extender to generate power at the target power can be directly determined. Similarly, if it is detected that the sum of the power values ​​is greater than or equal to the remaining power, there is no need to detect whether the power consumption of the first section is greater than or equal to the remaining power, and the preset power generation strategy for controlling the range extender to generate power at the target power can be directly determined.

[0073] For example, if the power consumption of the first section is 30 units and the remaining power is 25 units, there is no need to detect whether the total power is greater than or equal to the remaining power, and the preset power generation strategy for controlling the range extender to perform power generation operation at the target power generation power can be directly determined; similarly, if the total power is 35 and the remaining power is 25 units, there is no need to detect whether the power consumption of the first section is greater than or equal to the remaining power, and the preset power generation strategy for controlling the range extender to perform power generation operation at the target power generation power can be directly determined.

[0074] Specifically, the preset power generation strategy is that if it is detected that the current remaining power of the vehicle is reduced to the starting power percentage of the range extender (SOC str ), the range extender is controlled to generate electricity at the target power.

[0075] This embodiment provides another preset power generation strategy. By performing relevant tests and, if the pre-test conditions of this embodiment are met, the preset power generation strategy is determined to control the range extender to generate power at a target power level. This allows the range extender to operate at different power levels on different road sections, thereby improving the range extender's power generation efficiency and reducing fuel consumption while the vehicle is traveling.

[0076] In an exemplary embodiment of this application, how to calculate the target power generation is described in detail. Figure 6 , Figure 6 is based on Figures 3 to 5 A flowchart of another method for controlling a range extender based on navigation information is shown in any exemplary embodiment of FIG. The control method further includes S610 to S630, which are described in detail as follows:

[0077] S610: Obtain the voltage value, current value, and average efficiency of the drive motor, as well as the average power generation efficiency of the range extender and the power consumption of other accessories.

[0078] S620: Calculate the required power according to the voltage value and the current value.

[0079] S630: Calculate the target power generation according to the required power, the average efficiency of the drive motor, the average power generation efficiency of the range extender, and the power consumption of other accessories.

[0080] This embodiment is exemplified as follows: the target power generation is calculated according to the following formula:

[0081]

[0082] Wherein, U represents the voltage value of the driving motor; I represents the current value of the driving motor; η m Indicates the average efficiency of the drive motor; η n It represents the average power generation efficiency of the range extender. It is a preset parameter and can be determined based on the actual test results of the vehicle under the WLTC (World Light Vehicle Test Cycle) test cycle. a Indicates the power consumed by other accessories.

[0083] This embodiment provides a method for calculating the target power generation. The target power generation is quickly calculated through a simple formula, thereby improving the efficiency of the entire calculation process.

[0084] In an exemplary embodiment of the present application, it is described in detail how to calculate the road section power consumption required for the vehicle to travel in each different speed section based on the driving time and operating condition parameters required for the vehicle to travel in each different speed section. For details, please refer to Figure 7 , Figure 7 is based on Figures 1 to 5 A flowchart of another method for controlling a range extender based on navigation information is shown in any exemplary embodiment of FIG. The operating parameters include energy consumption per unit mileage and power consumption of load electrical appliances. The control method further includes S710 to S740 in S120, which are described in detail as follows:

[0085] S710: Traverse each speed section and use the traversed speed section as the target speed section.

[0086] S720: Obtain the target road length and target driving time corresponding to the target speed section.

[0087] S730: Multiplying the target road length and the energy consumption per unit mileage to obtain a first product, and multiplying the power consumption of the load electrical equipment and the target driving time to obtain a second product.

[0088] S740: The first product and the second product are summed to calculate the target section power consumption required for the vehicle to travel in the target speed section, so as to obtain the section power consumption required for the vehicle to travel in each different speed section.

[0089] For example, the second speed section is traversed, the road length and travel time of the second speed section are obtained, and the power consumption corresponding to the second speed section is calculated according to the following formula:

[0090] E = road length × energy consumption per unit mileage + load electrical power consumption × driving time;

[0091] Similarly, the road section power consumption corresponding to other speed sections is calculated to obtain the road section power consumption required for the vehicle to travel in each different speed section.

[0092] This embodiment provides a method for calculating the road section power consumption required for a vehicle to travel in various speed sections. The traversed speed section is used as the target speed section, and the target section power consumption is calculated based on the target road length, target travel time, energy consumption per mileage, and load electrical power consumption. The target section power consumption is then calculated one by one, ensuring that the vehicle's road section power consumption is accurate and complete.

[0093] See also Figure 8 , Figure 8 This is a flow chart of a control method for a range extender based on navigation information, according to a preferred embodiment of the present application. The details are as follows:

[0094] First, the user sends a destination navigation request to the third-party platform, and receives destination navigation information generated by the third-party platform in response to the destination navigation request.

[0095] Then, based on the received navigation information of the destination and the operating parameters of the vehicle, the total power consumption required for the vehicle to travel to the destination is calculated, and it is detected whether the total power consumption is less than the remaining power of the vehicle battery; if it is less, it indicates that the remaining power of the vehicle battery meets the power demand of the vehicle in the navigation section, that is, there is no need to control the range extender to perform power generation operation, that is, Figure 8 If it is greater than or equal to, then the road section power consumption required for the vehicle to travel in each speed section is calculated based on the driving time and operating parameters required for the vehicle to travel in each speed section.

[0096] Then, the power consumption of the specified road section (0-90kph speed section) is obtained, and it is detected whether the power consumption of the specified road section is less than the remaining power. If it is less, the estimated power generation of the range extender in the remaining section is calculated based on the remaining time and the preset power generation power of the range extender.

[0097] Furthermore, a specific preset power generation strategy is determined based on the relationship between (total power consumption - estimated power generation) and the remaining power, that is, Figure 8If it is greater than, then detect whether the power consumption in the 0-30kph speed section is less than the remaining power, and detect whether (power consumption in the speed section below 30kph - estimated power generation + power consumption in the speed section above 90kph) is less than the remaining power, and determine Case 4 and Case 5 based on the test results.

[0098] Specifically, Case 2 represents the control of the range extender to not generate electricity on road speeds below 90 kph, and to generate electricity at a constant preset power level on road speeds above 90 kph. The preset power level is the most efficient preset power level.

[0099] Case 3 controls the range extender to disable power generation on roads with speeds below 90 kph and to generate power at the target power level on roads with speeds above 90 kph. The target power level is calculated based on the vehicle's required power.

[0100] Case 4 controls the range extender to operate at a constant preset power level on roads with speeds above 90 kph, and at a target power level on roads with speeds below 90 kph. The preset power level is the most efficient one, while the target power level is calculated based on the vehicle's required power.

[0101] Case 5 indicates that if the vehicle's current remaining power is detected to be less than the starting power percentage of the range extender (SOC str ), the range extender is controlled to generate electricity at the target power.

[0102] This embodiment matches five preset power generation strategies based on multiple different detection results, and rationally plans the speed sections and power generation power for the range extender to perform power generation operations, so that the range extender can perform power generation operations at the power generation power adapted to the speed section, thereby improving the power generation efficiency of the range extender during vehicle driving.
