[0027] If the sum of the remaining driving range corresponding to the remaining flexible fuel and the remaining driving range corresponding to the remaining battery charge is greater than the target relative distance, the flexible fuel engine is controlled to operate according to the optimal efficiency strategy. If the flexible fuel engine cannot provide the required electrical energy to the vehicle, the motor is controlled to start so that the motor can use the remaining charge in the battery to provide electrical energy to the vehicle.

[0028] In one possible implementation, calculating the remaining driving range corresponding to the vehicle's flexible fuel reserve includes:

[0029] Calculate the flexible fuel consumption required per kilometer of vehicle travel according to the preset mileage calculation cycle;

[0030] Obtain the vehicle's remaining flexible fuel level;

[0031] The ratio of the remaining flexible fuel to the flexible fuel consumption required per kilometer of vehicle travel is taken as the driving range corresponding to the remaining flexible fuel of the vehicle.

[0032] In one possible implementation, a torque distribution operation is performed on the torque provided by the battery and the torque provided by the flexible fuel engine to obtain a torque distribution result, including:

[0033] Based on the remaining charge of the battery and the remaining flexible fuel in the vehicle, a torque distribution operation is performed on the torque provided by the battery and the torque provided by the flexible fuel engine to obtain the torque distribution result.

[0034] A second aspect of this application provides a vehicle operation control device, comprising:

[0035] The power consumption calculation module is used to calculate the target power consumption required for the vehicle to travel from its current position to the target parking point when the relative distance between the vehicle's current position and the target parking point is less than a preset distance, provided that the flexible fuel pressure is greater than the pressure threshold.

[0036] A power acquisition module is used to acquire the remaining power of the battery;

[0037] The first control module is used to control the flexible fuel engine to operate at a preset operating efficiency to provide electrical energy to the vehicle when the remaining power is less than a specified multiple of the target power consumption; wherein, the portion of the electrical energy generated by the flexible fuel engine that is not used by the vehicle is stored in the battery.

[0038] The second control module is used to control the motor to start and control the flexible fuel engine to idle when the remaining power is greater than a specified multiple of the target power consumption and the remaining power is greater than a preset power threshold, so that the motor can use the remaining power in the battery to provide power to the vehicle.

[0039] The third control module is used to control the flexible fuel engine to operate according to the optimal efficiency strategy when the remaining power is greater than a specified multiple of the target power consumption and the remaining power is less than a preset power threshold, and to control the motor to start when the flexible fuel engine cannot provide the required power to the vehicle, so that the motor can use the remaining power in the battery to provide power to the vehicle until the vehicle travels to the specified range of the target parking point.

[0044] By employing the above technical solution, this application provides a vehicle operation control method and related device. In this application, when the flexible fuel pressure is greater than a pressure threshold, it indicates that the flexible fuel can be effectively output to the flexible fuel engine. At this time, when the vehicle is about to stop, the target power consumption required for the vehicle to travel from its current location to the target parking point using only battery power is calculated. The remaining battery power is obtained. If the remaining power is less than a specified multiple of the target power consumption, since the flexible fuel can be effectively output to the flexible fuel engine, the flexible fuel engine is controlled to operate at a preset operating efficiency to provide electrical energy to the vehicle, improving vehicle energy efficiency. If the remaining power is greater than a specified multiple of the target power consumption and greater than a preset power threshold, it indicates that the current battery power is sufficient. The motor can be started and the flexible fuel engine can be controlled to idle, prioritizing the use of the remaining battery power to provide electrical energy to the vehicle, further improving vehicle energy efficiency. When the remaining battery power is greater than a specified multiple of the target power consumption and less than a preset power threshold, the flexible fuel engine is controlled to operate according to an optimal efficiency strategy to ensure its energy efficiency. If the flexible fuel engine cannot provide the vehicle with the required electrical energy, the electric motor is controlled to start, allowing it to utilize the remaining battery power to power the vehicle. Through the coordination of the fuel engine and the electric motor, the vehicle can be driven normally to the designated range of the target parking point. In other words, this application comprehensively considers the remaining battery power and uses appropriate components in the fuel engine and electric motor to power the vehicle in different scenarios, ensuring the vehicle's energy efficiency.

[0052] The embodiments of this application are described below with reference to the accompanying drawings. The terminology used in the implementation section of this application is for explaining specific embodiments only and is not intended to limit the scope of this application.

[0053] The embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0054] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0055] A flexible fuel engine is an internal combustion engine that uses flexible fuels (referring to carbon-neutral or zero-carbon emission fuels such as hydrogen, methanol, ammonia, and natural gas) as fuel. It generates power by burning flexible fuels, and its main emission is water vapor, which can reduce carbon dioxide emissions.

[0056] Currently, flexible fuel engines can be combined with batteries to power vehicles. Therefore, how to use flexible fuel and batteries to collaboratively power a vehicle when it is about to stop, in order to improve energy efficiency (maximizing energy utilization and avoiding energy waste), is a technical problem that urgently needs to be solved by those skilled in the art.

[0057] In this embodiment, the remaining battery power is taken into account, and corresponding components in the energy engine and motor are used to power the vehicle in different scenarios to ensure the vehicle's energy efficiency.

[0058] Specifically, when the flexible fuel pressure exceeds a pressure threshold, it indicates that the flexible fuel can be effectively supplied to the flexible fuel engine. At this point, as the vehicle is about to stop, the target power consumption required for the vehicle to travel from its current location to the target parking point using only battery power is calculated. The remaining battery power is then determined. If the remaining power is less than a specified multiple of the target power consumption, the flexible fuel engine is controlled to operate at a preset efficiency to provide power to the vehicle, improving its energy efficiency. If the remaining power exceeds both a specified multiple of the target power consumption and a preset power threshold, it indicates that the battery has sufficient charge. The motor can be started, and the flexible fuel engine can be controlled to idle, prioritizing the use of the remaining battery power to provide energy to the vehicle, further improving its energy efficiency. When the remaining power is greater than a specified multiple of the target power consumption and less than a preset power threshold, the flexible fuel engine is controlled to operate according to the optimal efficiency strategy to ensure the energy efficiency of the flexible fuel engine. When the flexible fuel engine cannot provide the required power to the vehicle, the electric motor is controlled to start so that the electric motor can use the remaining power in the battery to provide power to the vehicle. Through the cooperation of the energy engine and the electric motor, the vehicle can be driven normally to the specified range of the target parking point.

[0059] Based on the above, one embodiment of this application provides a vehicle operation control method, referring to... Figure 1 It can include:

[0060] S11. If the relative distance between the vehicle's current position and the target parking point is less than a preset distance when the flexible fuel pressure is greater than the pressure threshold, calculate the target power consumption required for the vehicle to travel from the current position to the target parking point when using only battery power.

[0061] In this embodiment, the flexible fuel can be hydrogen, ammonia, methanol, natural gas, etc., and the flexible fuel engine is an engine that uses flexible fuel as its energy source. Flexible fuel pressure refers to the pressure value of the flexible fuel tank (such as a hydrogen tank) that stores the flexible fuel; the higher the pressure value, the more flexible fuel is in the tank. In this embodiment, to ensure that the flexible fuel can be effectively output to the flexible fuel engine, a pressure threshold is set. If the flexible fuel pressure is greater than this threshold, it indicates that the current flexible fuel is sufficient and can continuously and stably provide energy to the flexible fuel engine.

[0062] In one embodiment, since the application scenario in this application is a scenario where a vehicle is about to stop, the pressure threshold should be set so that the vehicle can drive normally to the target parking point using only flexible fuel. Therefore, the pressure threshold should be greater than the pressure value corresponding to the amount of flexible fuel required for the vehicle to drive to the target parking point, so as to ensure that the vehicle can drive normally to the target parking point using only flexible fuel.

[0063] If the flexible fuel pressure is greater than a pressure threshold, and the relative distance between the vehicle's current location and the target parking point, determined based on vehicle navigation positioning, is less than a preset distance, then the vehicle is about to reach its destination and will park there. The preset distance can be configured according to actual needs; in this embodiment, a preset distance of 2 kilometers is used as an example. It should be noted that determining whether the flexible fuel pressure exceeds the pressure threshold can be done when the relative distance between the vehicle and the target parking point is greater than 2 kilometers.

[0064] When the vehicle is within 2 kilometers of the target parking point, a coordinated control strategy for the flexible fuel engine and electric motor is triggered. This allows for real-time monitoring of information such as the operating status of the flexible fuel engine, the status of the flexible fuel tank (e.g., hydrogen tank), and the battery charge. Furthermore, at this time, the target power consumption required for the vehicle to travel from its current location to the target parking point using only battery power can be calculated.

[0065] In one implementation, refer to Figure 2 Calculating the target power consumption required for the vehicle to travel from its current location to the target parking point using only battery power can include:

[0066] S21. Calculate the total resistance during the vehicle's movement.

[0067] The total resistance during vehicle movement includes rolling resistance and air resistance. The formula for calculating rolling resistance is:

[0068] F_rolling = m × g × Crr;

[0069] Where m is the vehicle weight, g is the gravitational acceleration, Crr (rolling resistance coefficient) ≈ 0.006-0.01, and the typical rolling resistance coefficient of truck tires is 0.008.

[0070] Taking a vehicle with a standard weight of 49 tons traveling 2 kilometers at a speed of 60 km / h as an example, its rolling resistance is:

[0071] F_rolling = 49000 × 9.81 × 0.008 ≈ 3845 N.

[0072] The formula for calculating air resistance is:

[0073] F_air = 1 / 2 × ρ × Cd × A × v 2 ;

[0074] Wherein, ρ (air density) ≈ 1.225 kg / m³, Cd (drag coefficient) ≈ 0.6-1.3 (typical value for trucks, take 0.8), A (frontal area) ≈ 10 m² (estimated value), v (vehicle speed) = 60 km / h = 16.67 m / s;

[0075] At this point, F_air = 0.5 × 1.225 × 0.8 × 10 × (16.67) 2 ≈1366 N.

[0076] Total resistance F_total = F_rolling + F_air = 3845 + 1366 ≈ 5211 N.

[0077] S22. Calculate the vehicle's required power based on the total resistance and the vehicle's speed.

[0078] In this embodiment, the vehicle's power requirement is represented by P, and the formula for calculating P is:

[0079] P = F_total × v = 5211 × 16.67 ≈ 86800 W = 86.8 kW. Where v is the vehicle's speed.

[0080] S23. Based on the required power, calculate the theoretical power consumption required for the vehicle to travel from its current location to the target parking point using only battery power.

[0081] In this embodiment, when estimating power consumption, it is assumed that the vehicle is driving under ideal conditions. Under the condition of using only battery power, the theoretical power consumption required for the vehicle to travel from the current location to the target parking point is: 86.8 × 2 / 60 = 2.89 kWh.

[0082] S24. Determine the actual power consumption corresponding to the theoretical power consumption.

[0083] In this embodiment, considering factors such as vehicle transmission efficiency and energy recovery, the actual power consumption will be greater than the theoretical power consumption. The actual power consumption is: 2.89 / 0.85 = 3.05 kWh. That is, 15% of the power will be consumed in vehicle transmission, energy recovery, etc., and only 85% of the power will be used for vehicle operation.

[0084] S25. Based on the vehicle's operating conditions, perform a correction operation on the actual power consumption to obtain the target power consumption.

[0085] In this embodiment, the vehicle's operating conditions can be divided into congested and uncongested conditions. In congested conditions, the vehicle's speed is slower, and more energy is consumed to reach the target parking point. Therefore, in this embodiment, if the vehicle is in congested conditions, a value greater than the actual energy consumption needs to be used as the target energy consumption, such as 1.2 times the actual energy consumption. If the vehicle is in uncongested conditions, the actual energy consumption can be directly used as the target energy consumption. In one example, when the vehicle's speed is below 20 km / h, it is considered congested; in this case, the actual energy consumption is multiplied by a coefficient of 1.2 to obtain the target energy consumption.

[0086] S12, Obtain the remaining battery power.

[0087] The remaining battery capacity can be represented by SOC (State of Charge). This can be obtained by communicating with the battery.

[0088] S13. When the remaining power is less than a specified multiple of the target power consumption, control the flexible fuel engine to operate at a preset operating efficiency to provide power to the vehicle.

[0089] Of the electrical energy generated by the flexible fuel engine, the portion not used by the vehicle is stored in the battery.

[0090] The specified multiple can be configured according to actual needs. In one example, the specified multiple is 1.5 times. If the remaining power is greater than the specified multiple of the target power consumption, it means that the current battery power is sufficient. The vehicle can be powered by the battery alone and can be driven to the target parking point.

[0091] If the remaining battery power is less than a specified multiple of the target power consumption, it indicates that the current battery power is not sufficient. Using only the battery to provide power to the vehicle may result in insufficient battery power to support the vehicle's journey to the target parking point due to factors such as congestion or high energy consumption when going uphill or downhill. In this case, to improve the vehicle's energy efficiency and avoid excessive battery discharge, this embodiment controls the flexible fuel engine to operate at a preset operating efficiency to provide power to the vehicle.

[0092] In one implementation, the preset operating efficiency can be a value within the high-efficiency range, such as a 90% power generation efficiency for the flexible fuel engine, to ensure optimal operation. In this case, the flexible fuel engine generates and stores energy, reducing the vehicle's overall electrical energy consumption. The power generation capacity of the flexible fuel engine is determined based on the current power demand. The required torque varies depending on factors such as power consumption, driving path (uphill / downhill, flat road, etc.), and throttle position. Since the power generation capacity of the flexible fuel engine = torque × engine speed / 9550, the power generation capacity of the flexible fuel engine can be calculated once the required torque and engine speed are known.

[0093] In real-world scenarios, such as uphill driving, in high-torque demand conditions, most or all of the electrical energy generated by the flexible fuel cell engine is used for vehicle operation. Any surplus is stored in the battery. In low-torque demand conditions, such as downhill driving, a portion of the electrical energy generated by the flexible fuel cell engine is used for vehicle operation, while the remainder is directly stored in the battery to increase its charge level. The battery is then recharged promptly after the vehicle stops.

[0094] S14. When the remaining power is greater than a specified multiple of the target power consumption and the remaining power is greater than a preset power threshold, control the motor to start and control the flexible fuel engine to idle, so that the motor can use the remaining power in the battery to provide power to the vehicle.

[0095] Specifically, if the remaining battery power is greater than a specified multiple of the target power consumption, it indicates that the current battery power is sufficient to power the vehicle to the target parking point. Further, it is determined whether the remaining battery power exceeds a preset battery power threshold, which is a high threshold, such as 98%. If the remaining battery power exceeds this threshold, it indicates that the current battery power is relatively high. During the flexible fuel engine's braking and energy recovery, the battery storage space is limited. Therefore, the battery should be discharged to free up space for energy recovery. At this time, the motor can be started, using the remaining battery power to provide power to the vehicle, consuming battery power to provide energy storage space for engine braking and energy recovery, ensuring effective energy recovery. Simultaneously, the flexible fuel engine is controlled to operate at low power, which can be idling, where the battery primarily powers the vehicle.

[0096] In this embodiment, when the battery is about to be fully charged, if there is a lot of braking, the motor is used to provide torque as the main method, while the engine outputs low power (low power consumption) to free up some electrical energy storage space in the battery to recover the energy generated during the braking process and improve overall efficiency.

[0097] S15. When the remaining power is greater than a specified multiple of the target power consumption and less than a preset power threshold, control the flexible fuel engine to operate according to the optimal efficiency strategy. When the flexible fuel engine cannot provide the required power to the vehicle, control the motor to start so that the motor can use the remaining power in the battery to provide power to the vehicle until the vehicle travels to the specified range of the target parking point.

[0098] Specifically, if the remaining power is greater than a specified multiple of the target power consumption and less than a preset power threshold, it indicates that the current battery power is sufficient and can provide energy storage space for energy recovery. In this case, the flexible fuel engine is used first to provide power to the vehicle, and the battery provides the remaining power.

[0099] When using a flexible fuel engine to provide electrical power to a vehicle, in order to improve energy efficiency, the flexible fuel engine can be controlled to operate according to an optimal efficiency strategy.

[0100] The most efficient strategy is:

[0101] In the universal curve of an engine, there is a region with the lowest fuel consumption (high-efficiency operating region), which is between 80% and 90% of the maximum torque. Energy consumption is lowest when operating in this region.

[0102] In one implementation, controlling the flexible fuel engine to operate according to an optimal efficiency strategy may include:

[0103] The efficient operating region in the engine operating curve is obtained, the target torque that enables the flexible fuel engine to operate in the efficient operating region is determined, and the flexible fuel engine is controlled to output torque according to the target torque.

[0104] like Figure 3 As shown, Figure 3 This is a schematic diagram of the engine's operating curve. In the engine operating curve, the upper left corner is the high-efficiency operating region (referred to as the high-efficiency zone), the middle is the transition zone, and the bottom is the low-efficiency operating region (referred to as the low-efficiency zone). In this embodiment, optimal efficiency means that the torque is located within the high-efficiency operating region. Therefore, in this embodiment, a target torque that allows the flexible fuel engine to operate within the high-efficiency operating region can be determined. Specifically, based on the vehicle's torque requirements, a target torque within the high-efficiency operating region can be selected, and then the flexible fuel engine can be controlled to output torque according to the target torque. That is, this embodiment adopts a driving mode prioritizing optimal efficiency based on real-time conditions, reducing engine hydrogen consumption and waste.

[0105] In one implementation, when the vehicle's torque demand is in an inefficient operating region, an electric motor should be used to provide the torque.

[0106] If the flexible fuel engine, operating under optimal efficiency, still cannot provide sufficient electrical energy for the vehicle, the electric motor needs to be started. This allows the motor to utilize the remaining battery power to power the vehicle, with both the engine and motor working together to provide electrical energy. If, however, the flexible fuel engine can provide sufficient electrical energy for the vehicle when operating under optimal efficiency, then starting the electric motor is unnecessary; the flexible fuel engine alone is sufficient to power the vehicle.

[0107] Using the aforementioned coordinated operation of the flexible fuel engine and electric motor, the vehicle is controlled to move until it reaches the designated area of ​​the target parking point. The designated area of ​​the target parking point refers to the vicinity of the target parking point, such as within 50 meters or 100 meters.

[0108] In one implementation, when the remaining power is greater than a specified multiple of the target power consumption and less than a preset power threshold, and when the vehicle has traveled to a specified range of the target parking point, the vehicle only uses the motor to provide the electrical energy required by the vehicle, and stops outputting flexible fuel to the flexible fuel engine and draining the flexible fuel in the pipeline located after the shut-off valve.

[0109] In practical implementation, since the reliability and safety of using an electric motor for power supply are relatively high, the output of flexible fuel to the flexible fuel engine is stopped before the vehicle stops, and the flexible fuel engine no longer supplies power. Additionally, because the different arrangements of the engine's pipelines (such as hydrogen supply pipelines) during flexible fuel engine operation can lead to some flexible fuel residue in the pipelines, to avoid the risk of leakage due to residual flexible fuel in the pipelines, in this embodiment, air can be used to purge the flexible fuel in the pipeline located after the shut-off valve, thereby improving safety after the vehicle stops.

[0110] Since the flexible fuel supply to the flexible fuel engine has stopped, the flexible fuel engine no longer provides power. At this time, only the electric motor is used to provide the electrical energy required by the vehicle. That is, the electric motor is used to complete the final stopping action when the vehicle stops.

[0111] In this embodiment, the motor is used to provide torque as much as possible before stopping, while the supply of flexible fuel to the flexible fuel engine is stopped and the flexible fuel in the pipeline is emptied to improve safety.

[0112] It should be noted that if the remaining power is less than a specified multiple of the target power consumption, the portion of the electrical energy generated by the flexible fuel engine that is not used by the vehicle will be stored in the battery, causing the battery power to continuously increase. When the remaining power is greater than a specified multiple of the target power consumption and less than a preset power threshold, the system will operate in the following manner: "controlling the flexible fuel engine to operate according to the optimal efficiency strategy, and controlling the motor to start when the flexible fuel engine cannot provide the required electrical energy to the vehicle, so that the motor can use the remaining power in the battery to provide electrical energy to the vehicle until the vehicle travels to the specified range of the target parking point."

[0113] Similarly, if, during the operation of "controlling the flexible fuel engine to operate according to the optimal efficiency strategy, and controlling the motor to start so that the motor can use the remaining battery power to provide power to the vehicle until the vehicle reaches the designated range of the target parking point," the condition that the remaining battery power is less than a specified multiple of the target power consumption is met, then the operation will proceed in the manner of "controlling the flexible fuel engine to operate according to the preset operating efficiency to provide power to the vehicle." That is, the above three situations (steps S13, S14, and S15) can be switched between each other according to the actual situation.

[0114] In summary, the embodiments of this application adjust the cooperative state of the flexible fuel engine and the electric motor according to the battery's charge level to achieve efficient energy use in the vehicle.

[0115] In one implementation, to enable the vehicle to perform the aforementioned vehicle operation control method, when the flexible fuel is hydrogen, the vehicle is equipped with components such as an ECU (Electronic Control Unit), navigation and positioning system, battery, short-term independent motor, flexible fuel tank (such as a hydrogen tank), sensors, shut-off valve, and brake energy recovery system. The ECU can be used to execute the vehicle operation control method described in this application embodiment. It should be noted that when the flexible fuel is other fuels (such as methanol or natural gas), the corresponding hardware needs to be changed accordingly.

[0116] In this embodiment, when the flexible fuel pressure is greater than a pressure threshold, it indicates that the flexible fuel can be effectively supplied to the flexible fuel engine. At this point, as the vehicle is about to stop, the target power consumption required for the vehicle to travel from its current location to the target parking point using only battery power is calculated. The remaining battery power is obtained. If the remaining power is less than a specified multiple of the target power consumption, since the flexible fuel can be effectively supplied to the flexible fuel engine, the flexible fuel engine is controlled to operate at a preset efficiency to provide power to the vehicle, improving vehicle energy efficiency. If the remaining power is greater than a specified multiple of the target power consumption and greater than a preset power threshold, it indicates that the battery power is sufficient. The motor can be started and the flexible fuel engine can be controlled to idle, prioritizing the use of the remaining battery power to provide power to the vehicle, further improving vehicle energy efficiency. When the remaining battery power is greater than a specified multiple of the target power consumption but less than a preset power threshold, the flexible fuel engine is controlled to operate according to an optimal efficiency strategy to ensure its energy efficiency. If the flexible fuel engine cannot provide the vehicle with the required electrical energy, the electric motor is activated to utilize the remaining battery power to power the vehicle. Through the coordination of the fuel engine and the electric motor, the vehicle can be driven normally to the designated range of the target parking point. In other words, this application comprehensively considers the remaining battery power to adjust the cooperative state of the flexible fuel engine and the electric motor, using appropriate components in the fuel engine and electric motor to power the vehicle in different scenarios to ensure the vehicle's energy efficiency.

[0117] Based on any of the above embodiments, refer to Figure 4 Vehicle operation control methods also include:

[0118] S31. When the flexible fuel pressure is less than the pressure threshold, calculate the driving range corresponding to the remaining flexible fuel of the vehicle.

[0119] In this embodiment, if the flexible fuel pressure is lower than the pressure threshold, it indicates that the current flexible fuel is insufficient and cannot continuously and stably provide energy to the flexible fuel engine. In this case, to avoid the vehicle being unable to reach the target parking point due to insufficient flexible fuel, the vehicle will be prioritized to go to a flexible fuel supply station (such as a hydrogen refueling station) for flexible fuel replenishment.

[0120] At this point, it is necessary to calculate the remaining driving range corresponding to the vehicle's remaining flexible fuel to determine whether the remaining flexible fuel is sufficient to drive the vehicle to a flexible fuel supply station.

[0121] In one implementation, when calculating the continuous driving range corresponding to the vehicle's remaining flexible fuel, the flexible fuel consumption required per kilometer of driving can be calculated according to a preset mileage calculation cycle. The preset mileage calculation cycle can be configured according to actual conditions, such as 10 minutes, meaning the flexible fuel consumption required per kilometer of driving is calculated every 10 minutes. Specifically, every 10 minutes, the vehicle's driving distance and hydrogen consumption within those 10 minutes are calculated, and the ratio of hydrogen consumption to driving distance is used as the flexible fuel consumption FC required per kilometer of driving under the current operating conditions.

[0122] Then, the vehicle's remaining flexible fuel level is obtained, specifically by collecting the vehicle's remaining flexible fuel level Q through sensors.

[0123] Finally, the ratio of the remaining flexible fuel to the flexible fuel consumption required per kilometer of vehicle travel is taken as the vehicle's remaining flexible fuel range. In other words, the result of calculating "remaining flexible fuel Q / flexible fuel consumption FC per kilometer of vehicle travel" is taken as the vehicle's remaining flexible fuel range L.

[0124] S32. If the remaining driving range corresponding to the remaining flexible fuel is less than the target relative distance between the vehicle's real-time location and the flexible fuel supply station, calculate the remaining driving range corresponding to the remaining battery charge of the vehicle.

[0125] In practice, if the remaining flexible fuel corresponds to a driving range greater than the target relative distance between the vehicle's real-time location and the flexible fuel supply station, it means that although the current remaining flexible fuel is low, it is possible to drive to the flexible fuel supply station using the remaining flexible fuel. At this time, the vehicle will drive under normal operating conditions, but a "refill flexible fuel" prompt will be output.

[0126] If the remaining flexible fuel allows for a shorter driving range than the target relative distance between the vehicle's real-time location and the flexible fuel station, it means that the remaining flexible fuel is insufficient to reach the station. In this case, since the battery still has remaining charge, it can be determined whether it's possible to reach the station using both the battery and flexible fuel simultaneously. First, the driving range corresponding to the remaining battery charge should be calculated. Specifically, this can be done similarly to the flexible fuel calculation: calculate the electricity required to travel each kilometer, obtain the remaining battery charge, and use the ratio of the remaining charge to the electricity required to travel each kilometer as the driving range corresponding to the remaining battery charge.

[0127] S33. Determine whether the sum of the remaining driving range corresponding to the remaining flexible fuel and the remaining driving range corresponding to the remaining battery charge is less than the target relative distance; if it is less, proceed to step S34; if it is greater, proceed to step S35.

[0128] In this embodiment, it is determined whether the sum of the remaining driving range corresponding to the remaining flexible fuel and the remaining driving range corresponding to the remaining battery charge is less than the target relative distance. In other words, it is to determine whether it is possible to drive normally to the flexible fuel supply station when using both battery and flexible fuel for power.

[0129] S34. Perform torque distribution operation on the torque provided by the battery and the torque provided by the flexible fuel engine to obtain the torque distribution result, and perform vehicle driving control according to the torque distribution result.

[0130] In practice, if the sum of the remaining driving range corresponding to the remaining flexible fuel and the remaining driving range corresponding to the remaining battery charge is less than the target relative distance, it means that even using both the battery and flexible fuel for power, the vehicle cannot reach a flexible fuel supply station. In this scenario, since there are many charging stations, the vehicle can find one to charge. At this point, a torque distribution operation can be performed between the torque provided by the battery (since the motor uses battery power, the torque provided by the battery is also the torque provided by the motor) and the torque provided by the flexible fuel engine. Since charging the vehicle is easier, the torque provided by the battery can be set to be greater than the torque provided by the flexible fuel engine in the torque distribution result. That is, the remaining battery charge is used first to provide power to the vehicle. The battery has a larger weight in the torque distribution, and the driving range is supplemented by charging when the vehicle is parked.

[0131] In one implementation, a torque distribution operation is performed on the torque provided by the battery and the torque provided by the flexible fuel engine to obtain a torque distribution result, which may include:

[0132] Based on the remaining battery charge and the vehicle's remaining flexible fuel, a torque distribution operation is performed on the torque provided by the battery and the torque provided by the flexible fuel engine to obtain the torque distribution result.

[0133] In practice, torque distribution can be performed according to a pre-configured ratio, allocating torque between the battery and the flexible fuel engine. Furthermore, the remaining battery charge and the vehicle's remaining flexible fuel level can also be considered during torque distribution. When the battery has a higher remaining charge compared to the remaining flexible fuel, more torque can be allocated to the battery; conversely, when the battery has a lower remaining charge, less torque can be allocated. This comprehensive consideration of the relative remaining battery charge and flexible fuel level yields a more reasonable torque distribution result, which is then used for vehicle driving control.

[0134] S35, control the flexible fuel engine to operate according to the optimal efficiency strategy, and control the electric motor to start when the flexible fuel engine cannot provide the required electrical energy to the vehicle, so that the electric motor can use the remaining power in the battery to provide electrical energy to the vehicle.

[0135] Specifically, if the sum of the remaining driving range corresponding to the remaining flexible fuel and the remaining driving range corresponding to the remaining battery charge is greater than the target relative distance, it indicates that using both battery and flexible fuel simultaneously will allow the vehicle to reach the flexible fuel supply station. In this case, to improve energy efficiency, the engine can be controlled to operate according to the optimal efficiency strategy, and a "refueling required" prompt will be output. The specific implementation of controlling the engine to operate according to the optimal efficiency strategy is explained in the corresponding section above.

[0136] In addition, when the flexible fuel engine is unable to provide the vehicle with the required electrical energy, the motor is controlled to start so that the motor can use the remaining power in the battery to provide electrical energy to the vehicle. For specific implementation, please refer to the corresponding description above.

[0137] In this embodiment, when the remaining flexible fuel is low, if the combined driving range supported by the flexible fuel and the driving range provided by the battery can cover the flexible fuel supply station, the engine is controlled to operate at optimal efficiency to improve energy efficiency. If the flexible fuel supply station cannot be covered, the battery is used first, that is, the electric power is consumed first, and the battery is charged in time after parking.

[0138] In summary, in this embodiment, before parking, based on the battery level, engine status, and flexible fuel tank status, the motor and flexible fuel engine work together to provide torque. By optimizing the flexible fuel supply, battery management, and system control during the parking process, efficient and safe parking operations are achieved, flexible fuel is used rationally to meet the high-efficiency operation requirements of the engine, improve the energy efficiency of flexible fuel and battery, and reduce energy consumption.
