Description

Technical Field

[0001] The present invention relates to the technical field of fuel cell vehicles, and particularly to a power generation power control method, device, equipment, storage medium and vehicle. Background Art

[0002] With the continuous progress of new energy vehicle technologies, fuel cell vehicles are developing faster and faster due to their advantages of low emissions, good economy and high energy conversion efficiency. The fuel cell adjusts the air compressor speed and the hydrogen circulation pump speed to regulate the air and hydrogen intake, thereby regulating the fuel cell power generation power.

[0003] Fuel cell vehicles mainly consist of a fuel cell system, a vehicle control unit (VCU), a battery management system (BMS), a motor (IPU) and related components. At present, the target power generation power of fuel cell vehicles is mainly calculated by the VCU according to the remaining power sent by the BMS. When only relying on the power of the power battery to control the output power of the fuel cell, the working characteristics of the fuel cell itself are not further considered. The fuel cell is sensitive to different operating states of the vehicle, resulting in the mismatch between the output power of the fuel cell and the actual required power, affecting the reliability and economy of the fuel cell. For example: in low-temperature environments and complex road conditions, fuel cell vehicles have problems with maintaining power. When there is a high power demand at low power (such as overtaking with a large throttle condition), the vehicle's acceleration ability is poor. In extreme cases, the vehicle may even break down and be unable to drive.

[0004] In related technologies, it is possible to identify the temperature level at which the vehicle is currently located based on the current temperature inside the power battery, and determine the target output power of the fuel engine on the vehicle according to the current temperature, so that the output power of the engine can be dynamically adjusted for different temperature levels, considering the influence of temperature factors on the engine output power, and ensuring sufficient power of the power battery. However, there are still certain limitations. The vehicle usage environment and the current state information of the vehicle are not fully considered, and there is a problem that the power cannot be maintained under low-temperature conditions.

[0037] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the protection scope of the present invention.

[0038] In one embodiment, as shown in Figure 1 the present invention provides a power generation power control method, which is applied to a fuel cell vehicle and includes the following steps:

[0039] S1. When the fuel cell of the vehicle starts, obtain the current environmental information of the location where the vehicle is located, the current state information of the vehicle, and the power generation power demand information of the vehicle.

[0040] Specifically, in the embodiment of the present invention, when the remaining power of the power battery is low, the fuel cell of the vehicle starts to operate, which avoids further reduction of the remaining power of the power battery and also avoids the long-term use of the power battery when the power is too low, resulting in a shortened service life of the power battery.

[0041] S2. Determine the target power generation power of the fuel cell according to the current environmental information of the location where the vehicle is located, the current state information of the vehicle, and the power generation power demand information of the vehicle.

[0042] S3. Output the target power generation power to the fuel cell.

[0043] Specifically, in the embodiment of the present invention, the control system of the vehicle transmits the target power generation power signal to the controller of the fuel cell through a dedicated communication interface (such as a CAN bus). The CAN bus has high reliability and real-time performance, which can ensure the accurate transmission of the signal. After receiving the target power generation power signal, the fuel cell controller adjusts various operating parameters inside the fuel cell, such as the fuel supply amount and the air intake amount, to achieve the target power generation power. At the same time, the fuel cell will monitor its own working state in real time, such as voltage and current, and transmit the feedback information back to the vehicle control system for further adjustment and optimization.

[0044] It should be noted that during the operation of the fuel cell according to the target power generation, the vehicle control system continuously monitors the changes in environmental information, vehicle status information, and power generation power demand information. Once these information change significantly, the system recalculates the target power generation and outputs the new target power generation to the fuel cell to ensure that the vehicle is always in the best operating state and improve energy utilization efficiency and driving performance.

[0045] This multi-dimensional information acquisition strategy helps to comprehensively understand the operating conditions and requirements of the vehicle. Compared with controlling the power generation only based on single or a small amount of information, it can more accurately adapt to various driving scenarios and improve the power generation efficiency of the fuel cell and the overall performance of the vehicle.

[0046] As a preferred implementation manner of this embodiment, the current environmental information of the location where the vehicle is located includes the environmental temperature and the road condition data to be traveled on the target section, and the target section is the section to be traveled within a preset distance in front of the vehicle; the current state information of the vehicle includes the vehicle speed and the remaining power of the power battery; the power generation power demand information of the vehicle includes the driver demand power or the parking demand power, and the driver demand power is determined according to the opening degree of the accelerator pedal or the brake pedal.

[0047] The environmental temperature has a significant impact on the performance of the fuel cell. In a low-temperature environment, the electrochemical reaction rate of the fuel cell will decrease, resulting in a decrease in power generation efficiency, and even additional heating equipment may be required to maintain normal operation. A high-temperature environment may affect the heat dissipation of the fuel cell and also have an adverse impact on its performance. Therefore, obtaining the environmental temperature information helps to consider the restriction of temperature on the performance of the fuel cell when determining the target power generation, so as to make a more reasonable power plan and ensure the stable operation of the fuel cell under different temperature conditions.

[0048] Knowing in advance the road conditions within a preset distance ahead, that is, the road condition data to be traveled on the target section, such as whether it is congested, the road slope, etc., can enable the vehicle to adjust the power generation in advance. For example, if the road ahead is a congested section and the vehicle starts and stops frequently, there is no need for too high a power generation; while if it is a long uphill section, more power needs to be provided by the fuel cell to overcome the work done by gravity. By combining the road condition data to determine the target power generation, the situation of power waste or insufficient power can be avoided, and the energy utilization efficiency can be improved.

[0049] The vehicle speed reflects the current driving state and power demand of the vehicle. When driving at a high speed, the vehicle needs more power to overcome air resistance, etc., and correspondingly has a greater demand for power generation; while when driving at a low speed or in an idle state, the required power generation is relatively small. Adjusting the fuel cell power generation according to the vehicle speed information can closely match the power generation with the actual driving demand of the vehicle and avoid unnecessary energy consumption.

[0050] As an important energy storage component of a fuel cell vehicle, the remaining power of the power battery affects the overall energy management strategy of the vehicle. When the remaining power of the power battery is sufficient, the fuel cell can appropriately reduce the power generation power and preferentially consume the electric energy of the power battery to extend the service life of the fuel cell or reduce fuel consumption. Conversely, when the power of the power battery is low, the fuel cell needs to increase the power generation power to provide sufficient energy for vehicle driving and battery charging.

[0051] Determining the driver's required power through the accelerator pedal opening or the brake pedal opening can directly reflect the driver's real-time demand for vehicle power. When the driver presses the accelerator pedal, the larger the opening, the higher the demand for power, and the fuel cell should correspondingly increase the power generation power to meet the acceleration demand; when the brake pedal is pressed, the vehicle may need to recover braking energy and at the same time adjust the power generation power to adapt to the vehicle deceleration state. This method of determining the power demand based on the driver's operation enhances the timeliness of vehicle power response and driving comfort.

[0052] When the vehicle is parked, although the vehicle is in a stationary state, there may still be some devices that require power support, such as in-vehicle electrical appliances, battery thermal insulation or heating systems, etc. Defining the parked vehicle's required power enables the fuel cell to generate power reasonably when parked, which not only meets the needs of the vehicle's electrical equipment but also avoids excessive power generation causing energy waste.

[0053] Further, as shown in Figure 2 Determining the target power generation power of the fuel cell according to the current environmental information of the vehicle's location, the current state information of the vehicle, and the power generation power demand information of the vehicle includes:

[0054] Obtain the first correspondence relationship between the environmental temperature B, the road condition data A to be traveled on the target road section, and the first power generation power P I as shown in Table 1. Then, according to the environmental temperature at the vehicle's location, the road condition data to be traveled on the target road section, and the first correspondence relationship, the first power generation power value is determined.

[0055] Table 1 The first correspondence relationship between environmental temperature, road condition data to be traveled on the target road section, and the first power generation power

[0056]

[0057] Obtain the second correspondence relationship between the vehicle speed C, the remaining power D of the power battery, and the second power generation power P II as shown in Table 2. Then, according to the vehicle speed, the remaining power of the power battery, and the second correspondence relationship, the second power generation power value is determined.

[0058] Table 2 Second correspondence relationship between vehicle speed, remaining power of power battery and second power generation power

[0059]

[0060] Obtain the third correspondence relationship between the first power generation power E, the second power generation power F and the third power generation power P III as shown in Table 3. Then, determine the third power generation power value according to the determined first power generation power value, second power generation power value and the third correspondence relationship

[0061] Table 3 Third correspondence relationship between the first power generation power, the second power generation power and the third power generation power

[0062]

[0063] Determine the target power generation power of the fuel cell according to the third power generation power value and the power generation power demand information of the vehicle

[0064] As a preferred implementation manner of this embodiment, the target power generation power of the fuel cell = a × third power generation power value + b × power generation power demand value, where a and b are weight coefficients, and the power generation power demand value is obtained based on the power generation power demand information of the vehicle

[0065] The present invention provides high flexibility for the calculation of power generation power by introducing weight coefficients a and b. Different vehicle driving scenarios, usage requirements, and the characteristics of fuel cells and the whole vehicle can optimize the calculation of the target power generation power by adjusting the values of a and b. For example, in scenarios where stable output of the fuel cell is emphasized, the value of weight coefficient a can be appropriately increased to make the third power generation power value account for a larger proportion in the target power generation power; while in scenarios where more attention is paid to real-time response to driver needs or other power generation power demand information, the value of weight coefficient b is increased to make the influence of the power generation power demand value on the target power generation power more significant. This enables the method to adapt to various types of fuel cell vehicles and diverse driving conditions

[0066] By combining the third power generation power value with the power generation power demand value obtained based on the power generation power demand information, the present invention means that when determining the target power generation power, it takes into account some factors related to the long-term operating state and overall performance optimization of the vehicle (reflected by the third power generation power value), and also takes into account the current specific power generation power demand (such as driver demand power or parking demand power, etc.). This way of comprehensively considering multiple factors can more comprehensively reflect the actual needs of the vehicle in different situations compared to determining the power generation power only relying on a single factor, and helps to achieve more efficient and reasonable power generation power control

[0067] As a preferred implementation of this embodiment, refer to Figure 3 As shown, before executing the power generation control method, obtain the remaining power of the vehicle's power battery. When the remaining power of the power battery does not exceed the first preset threshold, the fuel cell starts to operate, and the power generation control method is executed. When executing the power generation control method, continuously obtain the remaining power of the vehicle's power battery. When the remaining power of the power battery exceeds the second preset threshold, the fuel cell stops working.

[0068] The present invention ensures the priority use of the electric energy of the power battery by starting the fuel cell only when the remaining power of the power battery does not exceed the first preset threshold. This not only conforms to the economic principle of vehicle energy utilization, minimizes unnecessary startup and operation of the fuel cell, reduces fuel consumption, but also protects the fuel cell to a certain extent and extends its service life. Because frequent startup and shutdown of the fuel cell may cause additional losses to its internal electrochemical reaction components, and this startup strategy based on the power threshold reduces the occurrence of this situation. When the power of the power battery drops to a certain level, it may not be able to meet the normal driving requirements of the vehicle or the operation of key equipment. At this time, starting the fuel cell can timely provide power and electric energy for the vehicle, ensure the continuous and stable operation of the vehicle, avoid situations such as vehicle breakdown due to insufficient power, and improve the reliability and user experience of the vehicle.

[0069] During the power generation control process, stopping the fuel cell when the remaining power of the power battery exceeds the second preset threshold helps to optimize the energy management system of the entire vehicle. It avoids the continuous power generation of the fuel cell when the power of the power battery is sufficient, resulting in energy waste. At the same time, allowing the power battery to undertake part or all of the power consumption requirements of the vehicle when the power is relatively high can give full play to the advantages of the power battery in flexible charging and discharging and fast response speed, further improving the energy utilization efficiency of the vehicle. Appropriately stopping the operation of the fuel cell reduces the operation time and fuel consumption of the fuel cell, directly reducing the operation cost of the vehicle. For fuel cell vehicles using fuels such as hydrogen, the fuel cost is an important part of the operation cost. This strategy helps to save costs to the greatest extent while meeting the normal use of the vehicle.

[0070] Furthermore, using the real-time data collected by vehicle sensors, such as vehicle speed, acceleration, engine load and other information, combined with machine learning algorithms or preset driving condition recognition models, to continuously judge the current driving condition of the vehicle. Automatically adjust the first preset threshold and the second preset threshold according to different driving conditions to achieve more accurate energy management. For example, when it is recognized that the vehicle is in an urban congestion driving condition, appropriately reduce the first preset threshold to avoid premature startup of the fuel cell; while in the high-speed driving condition, appropriately increase the second preset threshold to make full use of the efficiency advantage of the fuel cell at high power output.

[0071] Furthermore, the vehicle control system establishes an adaptive learning model by long-term collecting and analyzing its own operation data, including power consumption under different working conditions, the start and stop frequencies of the fuel cell, and the vehicle performance. According to the feedback of these data, the threshold is automatically adjusted to continuously optimize the vehicle's energy management strategy to adapt to the performance changes of individual vehicles and the driving habits of different users.

[0072] To improve the system's thermal stability, a start-stop buffer mechanism is introduced. When the power of the power battery approaches the threshold, instead of immediately starting or stopping the fuel cell, it enters a buffer state. For example, when the power approaches the first preset threshold, the fuel cell is first started for low-power preheating operation to ensure that its performance is in good condition before officially starting high-power power generation; when the power approaches the second preset threshold, the power generation power of the fuel cell is gradually reduced to enable the vehicle to smoothly transition to the state of relying only on the power battery for power supply. This can reduce the impact caused by the frequent start and stop of the fuel cell and improve the system stability.

[0073] During the start and stop processes of the fuel cell, by optimizing the vehicle's power distribution and control system, a smooth transition during the power source switch is ensured. For example, using the auxiliary control of the motor, when the fuel cell starts, the motor intervenes in advance to provide additional power to make up for the slow increase in power at the initial stage of the fuel cell start; when the fuel cell stops, the motor gradually takes over the power output to avoid power interruption. At the same time, the vehicle's transmission system is optimized for control to reduce the jerks caused by power switching and improve driving comfort and safety.

[0074] In another embodiment, the present invention provides a power generation power control device, as shown in Figure 4 The device includes an acquisition module 10, a determination module 20, and a response module 30.

The response module 30 is configured to output the target power generation power to the fuel cell.

[0075] As a preferred implementation manner of this embodiment, the determination module includes a first determination element, a second determination element, a third determination element, and a fourth determination element.
