Description

Technical Field

[0001] The present invention relates to the field of hydrogen-powered power-assisted vehicle management, and in particular to a whole-vehicle hybrid control method and system for a hydrogen-powered power-assisted vehicle. Background Art

[0002] The application of hydrogen fuel cell technology has begun to be multi-scenario. Shared bicycles are widely used in major cities, making people's travel more convenient. Shared bicycles are divided into human-powered and electric types. In the field of electric shared bicycles, many hydrogen energy companies have launched their own hydrogen-powered bicycles, with the aim of reducing the dependence of shared bicycles on lithium batteries to a certain extent, increasing the range of bicycles, reducing the number of charging times, and reducing the weight of the entire vehicle. There are currently two mainstream technical routes for hydrogen-powered bicycles: ① Using a combination of larger-capacity lithium batteries and fuel cell systems, in which lithium batteries provide a large proportion of electricity during use; ② Using a combination of very small-capacity lithium batteries and fuel cell systems, which are completely powered by the fuel cell system during use, and small-capacity lithium batteries are used to power the controller.

[0003] The purpose of power-assisted bicycles is to alleviate the problem of laborious riding of human-powered bicycles, while allowing riders to enjoy a certain amount of riding pleasure and increase the effect of exercise. However, technical route ① still uses large-capacity lithium batteries, which will make users rely on lithium battery power to a certain extent, and there will still be problems with frequent maintenance and charging. Technical route ② uses a fuel cell system to provide power assistance. Lithium batteries only provide starting power when the system is started. This cannot provide power assistance in some special occasions such as climbing a slope or going up a bridge. It is actually equivalent to human-powered bicycles, and the user experience is poor.

[0004] The problems in both technical routes ① and ② are that the control chip of the DC / DC boost controller used in the fuel cell system is an analog integrated chip, which is matched with peripheral power devices to realize the boost function. Other control and coordination functions require another MCU control chip to complete, which directly leads to the untimely response of the vehicle's power system and the inability to improve and optimize the energy management strategy, resulting in a relatively poor user experience. Summary of the invention

[0005] Based on this, it is necessary to provide a method and system for hybrid control of a hydrogen-powered vehicle to address the problem of real-time fuel cell system and energy storage system energy updates on the random on-board energy consumption monitoring interface.

[0006] A whole vehicle hybrid control method for a hydrogen-powered vehicle, comprising:

[0007] Collect the operation and control indicators of the fuel cell system and energy storage system in the hydrogen-powered vehicle platform;

[0008] The operation and control indicators of the fuel cell system and the energy storage system in the hydrogen-powered vehicle platform are used to use the on-board energy consumption monitoring interface to perform real-time fuel cell system and energy storage system energy updates, and the on-board energy consumption monitoring interface performs real-time fuel cell system and energy storage system energy updates including the operating status information of the hydrogen-powered vehicle platform;

[0009] Using the on-board energy consumption monitoring interface to update the energy control efficiency of the fuel cell system and the energy storage system in real time;

[0010] Calculate whether the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update is greater than a preset control index;

[0011] When the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update is calculated to be greater than the preset control index, the on-board energy consumption monitoring interface used for real-time fuel cell system and energy storage system energy update is calculated to each hydrogen power-assisted vehicle unit data control platform respectively; when the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update is calculated to be no greater than the preset control index, the operation and control index calculation of the fuel cell system and energy storage system in the hydrogen power-assisted vehicle platform is performed again, the on-board energy consumption monitoring interface is used for real-time fuel cell system and energy storage system energy update and the control efficiency is calculated.

[0012] When the on-board energy consumption monitoring interface receives the power-on command from the instrument switch, it will wake up the fuel cell control system and read the SOC of the energy storage system. When there is no abnormal signal on the communication bus, the fuel cell control system will activate the intake valve, exhaust valve, and cooling system and detect the hydrogen pressure and stack temperature indicators to adjust the stack to the best operating state. The fuel cell control system reads the required power of the motor controller and the SOC of the energy storage system from the communication bus, and calculates the PWM duty cycle based on the reading results to intelligently adjust the output power ratio of the DCDC boost unit and the energy storage system.

[0013] When the vehicle is powered on and starts riding normally, the motor controller reads the torque index required by the torque sensor and quickly calculates the required output power, and sends the output power index to the fuel cell control system through the bus. After receiving the index, the fuel cell control system dynamically adjusts the output power ratio of the stack and the energy storage system, and the motor controller picks up electrical energy from the DC bus to drive the motor for assistance.

[0014] The on-board energy consumption monitoring interface performs overall scheduling of the fuel cell control system and motor controller, and is also responsible for controlling other key components of the vehicle and processing user input information and demand information.

[0015] A whole vehicle hybrid control system of a hydrogen-powered electric vehicle, comprising:

[0016] A unit for building the operating status information of the hydrogen-powered vehicle platform, which is used to collect the operating and control indicators of the fuel cell system and energy storage system in the hydrogen-powered vehicle platform;

[0017] An energy update and use unit is connected to the hydrogen-powered vehicle platform operation status information building unit, and is used to use the operation and control indicators of the fuel cell system and the energy storage system in the hydrogen-powered vehicle platform to use the on-board energy consumption monitoring interface to perform real-time fuel cell system and energy storage system energy updates, and the on-board energy consumption monitoring interface performs real-time fuel cell system and energy storage system energy updates including hydrogen-powered vehicle platform operation status information;

[0018] A control efficiency calculation unit, connected to the energy update and use unit, for calculating the control efficiency of the on-board energy consumption monitoring interface used by the energy update and use unit for real-time fuel cell system and energy storage system energy update;

[0020] The hydrogen-powered vehicle unit data transmission unit is connected to the energy update and use unit and the control efficiency decision unit. It is used to use the signal from the control efficiency decision unit indicating that the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update is greater than the preset control index, and the on-board energy consumption monitoring interface used by the energy update and use unit for real-time fuel cell system and energy storage system energy update is calculated to each hydrogen-powered vehicle unit data control platform.

[0021] A hydrogen-powered bicycle unit abnormal data control efficiency building unit is used to update the control efficiency of each hydrogen-powered bicycle unit abnormal data required for the control efficiency calculation of the on-board energy consumption monitoring interface performed by the control efficiency calculation unit for real-time fuel cell system and energy storage system energy update, wherein the hydrogen-powered bicycle unit abnormal data control efficiency building unit is used to calculate the control efficiency and initial information of the hydrogen-powered bicycle unit abnormal data, and is used to calculate the secondary information of the hydrogen-powered bicycle unit abnormal data by using the probability of occurrence of the hydrogen-powered bicycle unit abnormal data in the real-time fuel cell system and energy storage system energy update using the on-board energy consumption monitoring interface used by the energy update use unit, and uses the control efficiency, initial information, and secondary information to calculate the new control efficiency of the hydrogen-powered bicycle unit abnormal data.

[0022] Beneficial effects:

[0023] The present invention proposes a method and system for controlling the whole vehicle hybrid of a hydrogen-powered power-assisted vehicle. The control efficiency of the real-time fuel cell system and energy storage system energy update is calculated by the on-board energy consumption monitoring interface and compared with the preset control index, so as to realize the management of the real-time fuel cell system and energy storage system energy update on the on-board energy consumption monitoring interface by managing the control efficiency of the real-time fuel cell system and energy storage system energy update on the on-board energy consumption monitoring interface. Compared with the problems of troublesome prediction and low accuracy caused by the existing random calculation, the present invention realizes the management of the difficulty of calculation management, operability and the horizontal difference of the real-time fuel cell system and energy storage system energy update on the on-board energy consumption monitoring interface by managing the control efficiency of the real-time fuel cell system and energy storage system energy update on the on-board energy consumption monitoring interface, thereby improving the usability of the hydrogen-powered power-assisted vehicle unit data control platform, and improving the accuracy of calculation and the control efficiency of the hydrogen-powered power-assisted vehicle data. The subcomponents of the whole vehicle of the present invention are connected through a high-speed communication bus, and the operation of the whole vehicle is generally dispatched by the central control system, and the dispatch response is rapid. The fuel cell controller uses a single MCU, which can not only complete the digital control of the DC / DC boost function, but also quickly process the power request issued by the motor controller through the high-speed bus to complete the energy strategy management. The energy storage system has a small capacity, and most of the working conditions are in floating charge (lithium battery) or voltage regulation (supercapacitor) state. Under special working conditions, it provides the peak power demand issued by the motor controller, which greatly improves the user's riding experience. Because the capacity of the energy storage system is significantly reduced, the volume of the whole vehicle hybrid system and the weight of the whole vehicle are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 This is a flow chart of a method for controlling the hybrid operation of a hydrogen-powered vehicle according to the present invention;

[0025] Figure 2 This is a composition diagram of a whole vehicle hybrid control system unit of a hydrogen-powered power-assisted vehicle of the present invention. DETAILED DESCRIPTION

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, it is a process of a whole vehicle hybrid control method of a hydrogen-powered power-assisted vehicle according to an embodiment of the present invention.

[0028] Step 102, collect the operation and control indicators of the fuel cell system and the energy storage system in the hydrogen-powered vehicle platform. For calculation management with specific content, the operation status information of the hydrogen-powered vehicle platform is preferably the factor with the greatest influence on the calculation management calculated using the calculation management content. Generally, obtaining the operation status information of the hydrogen-powered vehicle platform should be conducive to completing the abnormal data of the hydrogen-powered vehicle unit set according to the calculation management content. For example, for confrontational calculation management, the operation status information of the hydrogen-powered vehicle platform can be set to the target feature or role with the greatest combat effectiveness. The operation and control indicators of the fuel cell system and the energy storage system in the hydrogen-powered vehicle platform may include: the number, size, location, etc. of the operation status information of the hydrogen-powered vehicle platform.

[0029] Step 104, using the operation and control indicators of the fuel cell system and the energy storage system in the hydrogen-powered vehicle platform to use the on-board energy consumption monitoring interface to perform real-time fuel cell system and energy storage system energy updates, and the on-board energy consumption monitoring interface performs real-time fuel cell system and energy storage system energy updates including the operating status information of the hydrogen-powered vehicle platform.

[0030] Specifically, the on-board energy consumption monitoring interface used for real-time fuel cell system and energy storage system energy update should include the operating status information of the hydrogen-powered vehicle platform. The on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update should include the on-board energy consumption monitoring interface to be calculated to each hydrogen-powered vehicle unit data control platform using the calculation management content to perform real-time fuel cell system and energy storage system energy update, wherein the hydrogen-powered vehicle platform operating status information is included in the on-board energy consumption monitoring interface to be calculated to one or more hydrogen-powered vehicle unit data control platforms for real-time fuel cell system and energy storage system energy update. For example, the operating status information of the hydrogen-powered vehicle platform should be used when the on-board energy consumption monitoring interface is used for real-time fuel cell system and energy storage system energy update and included in the on-board energy consumption monitoring interface used for real-time fuel cell system and energy storage system energy update.

[0031] Step 106, calculating the control efficiency of the on-board energy consumption monitoring interface of the data control platform of each hydrogen-powered vehicle unit for real-time fuel cell system and energy storage system energy update.

[0032] Specifically, the on-board energy consumption monitoring interface to be calculated to each hydrogen-powered vehicle unit data control platform can be used to perform real-time fuel cell system and energy storage system energy updates, and the on-board energy consumption monitoring interface to be calculated to the hydrogen-powered vehicle unit data control platform is used to calculate the control efficiency of real-time fuel cell system and energy storage system energy updates. It can be understood that the on-board energy consumption monitoring interface generated by the random calculation method is used to perform real-time fuel cell system and energy storage system energy updates, and the differences in difficulty, operability, etc. are also random, so that unexpected unevenness may occur in the same calculation management and the same period of time, and this unexpected unevenness is also one of the important reasons why the existing random calculation principle affects the user's prediction trouble and stickiness. Using an embodiment of the present invention, calculating the control efficiency of the on-board energy consumption monitoring interface of each hydrogen-powered vehicle unit data control platform for real-time fuel cell system and energy storage system energy updates is an important means of managing the existing random calculation principle.

[0033] Step 108, calculating the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update.

[0034] Using an embodiment of the present invention, the control efficiency can be calculated based on the control efficiency of the real-time fuel cell system and energy storage system energy update of the on-board energy consumption monitoring interface of each hydrogen-powered vehicle unit data control platform calculated in step 106. Of course, using other feasible implementations, it is also possible to calculate the control efficiency of the real-time fuel cell system and energy storage system energy update of the on-board energy consumption monitoring interface used by performing preset operations on all used on-board energy consumption monitoring interfaces. In this case, the calculation of the real-time fuel cell system and energy storage system energy update control efficiency of the on-board energy consumption monitoring interface of each hydrogen-powered vehicle unit data control platform in step 106 may not be performed.

[0035] In this embodiment, the control efficiency reflects the difficulty and operability of the calculation management content reflected by the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update, as well as the difference between the on-board energy consumption monitoring interface of each hydrogen-powered vehicle unit data control platform for real-time fuel cell system and energy storage system energy update. Through the control efficiency, the difference in the difficulty and operability of the on-board energy consumption monitoring interface calculated by each hydrogen-powered vehicle unit data control platform for real-time fuel cell system and energy storage system energy update can be obtained, which can be distinguished from the unexpected difficulty, operability and difference reflected in the existing random calculation principle.

[0036] Step 110 , calculating whether the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update is greater than a preset control index.

[0037] Specifically, the preset control index can be set by using the various calculation management elements contained in the real-time fuel cell system and energy storage system energy update using the on-board energy consumption monitoring interface, and the difference between the real-time fuel cell system and energy storage system energy update using the on-board energy consumption monitoring interface of each hydrogen energy booster unit data control platform. In this embodiment, when the control efficiency of the real-time fuel cell system and energy storage system energy update by the on-board energy consumption monitoring interface is not greater than the preset control index, it indicates that the overall calculation management difficulty, operability and the difference between the real-time fuel cell system and energy storage system energy update by the on-board energy consumption monitoring interface of each hydrogen energy booster unit data control platform exceed expectations, and it is necessary to re-perform the process of calculating the operating status information of the hydrogen energy booster platform, using the on-board energy consumption monitoring interface to perform real-time fuel cell system and energy storage system energy update, and calculating the control efficiency described in steps 102 to 108, until the control efficiency of the real-time fuel cell system and energy storage system energy update by the on-board energy consumption monitoring interface meets the expected difficulty, operability and difference expectations, that is, the control index is greater than the preset control index.

[0038] Step 112, if the control efficiency of the on-board energy consumption monitoring interface calculated in step 110 for real-time fuel cell system and energy storage system energy update is greater than the preset control index, the on-board energy consumption monitoring interface used for real-time fuel cell system and energy storage system energy update is calculated separately to each hydrogen power-assisted vehicle unit data control platform.

[0039] In this embodiment, the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update reflects the overall difficulty, operability and individual differences of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update to be calculated for each hydrogen power-assisted vehicle unit data control platform. If the control efficiency is greater than the preset control index, it indicates that the overall difficulty, operability and individual differences of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update of each hydrogen power-assisted vehicle unit data control platform meet the required expectations, and each hydrogen power-assisted vehicle unit data control platform can use the on-board energy consumption monitoring interface to start calculation management for real-time fuel cell system and energy storage system energy update.

[0040] In an optional implementation, before calculating the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update of each user in step 106, or before calculating the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update in step 108, the on-board energy consumption monitoring interface used for real-time fuel cell system and energy storage system energy update calculation can be sent to each hydrogen-powered vehicle unit data control platform. Thus, when it is calculated that the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update is not greater than the preset control index and it is necessary to recalculate the operation and control index of the fuel cell system and energy storage system in the hydrogen-powered vehicle platform and use the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update, it is necessary to delete or withdraw the calculated on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update from each hydrogen-powered vehicle unit data control platform.

[0041] Step 114, when the on-board energy consumption monitoring interface receives the power-on command from the instrument switch, it wakes up the fuel cell control system and reads the SOC of the energy storage system. When there is no abnormal signal on the communication bus, the fuel cell control system activates the intake valve, exhaust valve, and cooling system and detects the hydrogen pressure and stack temperature indicators to adjust the stack to the best operating state; the fuel cell control system reads the required power of the motor controller and the SOC of the energy storage system from the communication bus, calculates the PWM duty cycle based on the reading result, and intelligently adjusts the output power ratio of the DCDC boost unit and the energy storage system;

[0042] Step 116, when the motor control system and its subcomponents are powered on normally and start riding, the motor controller reads the torque index required by the torque sensor and quickly calculates the required output power, and sends the output power index to the fuel cell control system through the bus. After receiving the index, the fuel cell control system dynamically adjusts the output power ratio of the stack and the output power ratio of the energy storage system, and the motor controller picks up electric energy from the DC bus to drive the motor for assistance;

[0043] Step 118, the vehicle-mounted energy consumption monitoring interface performs overall scheduling of the fuel cell control system and the motor controller, and is also responsible for controlling other key components of the vehicle and processing user input information and demand information.

[0044] Furthermore, when the on-board energy consumption monitoring interface receives the power-on command from the instrument switch, it will wake up the fuel cell control system and read the SOC of the energy storage system. When there is no abnormal signal on the communication bus, the fuel cell control system will activate the intake valve, exhaust valve, and cooling system to detect the hydrogen pressure and stack temperature indicators at the same time to adjust the stack to the best operating state; the fuel cell control system includes a DCDC boost unit and an all-in-one control board, and the DCDC boost unit is digitally controlled by an MCU. First, the control system will read the required power of the motor controller and the SOC of the energy storage system from the communication bus, and calculate the PWM duty cycle based on the reading results to intelligently adjust the output power ratio of the DCDC boost unit and the energy storage system. The capacity of the energy storage system does not need to be too large. Under normal riding conditions, the fuel cell system can provide most of the output power to keep the energy storage system in a floating charge state. When special conditions such as climbing occur, the energy storage system can provide peak power support in a short time. The heating system is responsible for temperature regulation when the temperature of the hydrogen storage bottle is low.

[0045] Furthermore, the motor control system and its subcomponents mainly include a motor controller, a motor, front and rear lights, and a torque sensor. The front and rear lights can be intelligently controlled to turn on and off through the communication bus, and the riding pedals are connected to the torque sensor. The control operation logic of the system is: when the vehicle is powered on normally and starts riding, the motor controller will read the torque index required by the torque sensor and quickly calculate the required output power, and give the output power index to the fuel cell control system through the bus. The fuel cell control system will dynamically adjust the output power of the stack and the output power ratio of the energy storage system after obtaining the index. The motor controller will pick up electrical energy from the DC bus to drive the motor for assistance.

[0046] Furthermore, the on-board energy consumption monitoring interface and its subcomponents mainly include horns, hydrogen tank locks, brake locks, instrument switches, and auxiliary power systems (required when the energy storage system is a supercapacitor). The on-board energy consumption monitoring interface is mainly responsible for the overall scheduling of the fuel cell control system and the motor controller, as well as the control of other key components of the vehicle and the processing of user input information and demand information.

[0047] like Figure 2 As shown, it is a schematic diagram of the structure and function of a hydrogen-powered vehicle hybrid control system according to an embodiment of the present invention. The system includes:

[0048] The hydrogen-powered vehicle platform operation status information building unit is used to collect the operation and control indicators of the fuel cell system and energy storage system in the hydrogen-powered vehicle platform.

[0049] For calculation management with specific content, the operating status information of the hydrogen-powered vehicle platform is preferably the factor with the greatest influence on the calculation management calculated using the calculation management content. Generally, obtaining the operating status information of the hydrogen-powered vehicle platform should be conducive to completing the abnormal data of the hydrogen-powered vehicle unit set according to the calculation management content. For example, for confrontational calculation management, the operating status information of the hydrogen-powered vehicle platform can be set to the target feature or role with the greatest combat effectiveness. The operation and control indicators of the fuel cell system and the energy storage system in the hydrogen-powered vehicle platform may include: the number, size, location, etc. of the operating status information of the hydrogen-powered vehicle platform.

[0050] The energy update utilization unit is used to utilize the operation and control indicators of the fuel cell system and the energy storage system in the hydrogen-powered assisted vehicle platform to use the on-board energy consumption monitoring interface to perform real-time fuel cell system and energy storage system energy updates. The on-board energy consumption monitoring interface performs real-time fuel cell system and energy storage system energy updates including the operating status information of the hydrogen-powered assisted vehicle platform.

[0051] Specifically, in the on-board energy consumption monitoring interface used by the energy update usage unit to perform real-time fuel cell system and energy storage system energy updates, the operating status information of the hydrogen energy-assisted vehicle platform shall be included. The on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy updates shall include the on-board energy consumption monitoring interface to be calculated to each hydrogen energy-assisted vehicle unit data control platform using the calculation management content to perform real-time fuel cell system and energy storage system energy updates, wherein the hydrogen energy-assisted vehicle platform operating status information is included in the on-board energy consumption monitoring interface to be calculated to one or more hydrogen energy-assisted vehicle unit data control platforms for real-time fuel cell system and energy storage system energy updates. For example, the operating status information of the hydrogen energy-assisted vehicle platform shall be used when the energy update usage unit uses the on-board energy consumption monitoring interface to perform real-time fuel cell system and energy storage system energy updates and shall be included in the on-board energy consumption monitoring interface used to perform real-time fuel cell system and energy storage system energy updates.

[0052] The control efficiency calculation unit is used to calculate the control efficiency of the on-board energy consumption monitoring interface of the data control platform of each hydrogen-powered vehicle unit for real-time fuel cell system and energy storage system energy update, and calculate the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update.

[0053] Specifically, the control efficiency calculation unit can use the on-board energy consumption monitoring interface to be calculated to each hydrogen-powered vehicle unit data control platform used by the energy update use unit to perform real-time fuel cell system and energy storage system energy update, and calculate the control efficiency of the on-board energy consumption monitoring interface to be calculated to the hydrogen-powered vehicle unit data control platform for real-time fuel cell system and energy storage system energy update. It can be understood that the on-board energy consumption monitoring interface generated by the random calculation method is used to perform real-time fuel cell system and energy storage system energy update, and the differences in difficulty, operability, etc. are also random, so that unexpected unevenness may occur in the same calculation management and the same period of time, and this unexpected unevenness is also one of the important reasons why the existing random calculation principle affects the trouble and stickiness of user prediction. Using an embodiment of the present invention, using the control efficiency calculation unit to calculate the control efficiency of the on-board energy consumption monitoring interface of each hydrogen-powered vehicle unit data control platform for real-time fuel cell system and energy storage system energy update is an important means to manage the existing random calculation principle.

[0054] Using an embodiment of the present invention, the control efficiency calculation unit can calculate the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update based on the calculated control efficiency of the on-board energy consumption monitoring interface of each hydrogen power-assisted vehicle unit data control platform for real-time fuel cell system and energy storage system energy update. Of course, using other feasible implementations, it is also possible to calculate the control efficiency of the on-board energy consumption monitoring interface used by the energy update use unit for real-time fuel cell system and energy storage system energy update by performing preset operations on all on-board energy consumption monitoring interfaces used by the energy update use unit. In this case, the control efficiency calculation unit may not calculate the control efficiency of the on-board energy consumption monitoring interface of each hydrogen power-assisted vehicle unit data control platform for real-time fuel cell system and energy storage system energy update.

[0055] In this embodiment, the control efficiency reflects the difficulty and operability of the calculation management content reflected by the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update, as well as the difference between the on-board energy consumption monitoring interface of each hydrogen-powered vehicle unit data control platform for real-time fuel cell system and energy storage system energy update. Through the control efficiency, the difference in the difficulty and operability of the on-board energy consumption monitoring interface calculated by each hydrogen-powered vehicle unit data control platform for real-time fuel cell system and energy storage system energy update can be obtained, which can be distinguished from the unexpected difficulty, operability and difference reflected in the existing random calculation principle.

[0056] The control efficiency decision unit is used to calculate whether the control efficiency of the real-time fuel cell system and energy storage system energy update performed by the on-board energy consumption monitoring interface is greater than a preset control index.

[0057] Specifically, the preset control index can be set by utilizing the various calculation management elements contained in the real-time fuel cell system and energy storage system energy update using the on-board energy consumption monitoring interface, and utilizing the on-board energy consumption monitoring interface of each hydrogen-powered vehicle unit data control platform to perform real-time fuel cell system and energy storage system energy update The difference is required. In this embodiment, when the control efficiency decision unit calculates the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update is not greater than the preset control index, it indicates that the difficulty and operability of the overall calculation management and the difference between the on-board energy consumption monitoring interface of each hydrogen energy assisted vehicle unit data control platform for real-time fuel cell system and energy storage system energy update are beyond expectations, then it is necessary to notify the hydrogen energy assisted vehicle platform operation status information building unit, the energy update use unit, and the control efficiency calculation unit to respectively perform the above-mentioned process of calculating the hydrogen energy assisted vehicle platform operation status information, using the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update, and calculating the control efficiency again, until the control efficiency decision unit calculates the control efficiency of the on-board energy consumption monitoring interface used for real-time fuel cell system and energy storage system energy update to meet the expected difficulty, operability and difference expectations, that is, the control index is greater than the preset control index.

[0058] The hydrogen-powered vehicle unit data transmission unit is connected to the energy update and use unit and the control efficiency decision unit. It is used to use the signal from the control efficiency decision unit indicating that the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update is greater than the preset control index, and the on-board energy consumption monitoring interface used by the energy update and use unit for real-time fuel cell system and energy storage system energy update is calculated to each hydrogen-powered vehicle unit data control platform.

[0059] A hydrogen-powered bicycle unit abnormal data control efficiency building unit is used to update the control efficiency of each hydrogen-powered bicycle unit abnormal data required for the control efficiency calculation of the on-board energy consumption monitoring interface performed by the control efficiency calculation unit for real-time fuel cell system and energy storage system energy update, wherein the hydrogen-powered bicycle unit abnormal data control efficiency building unit is used to calculate the control efficiency and initial information of the hydrogen-powered bicycle unit abnormal data, and is used to calculate the secondary information of the hydrogen-powered bicycle unit abnormal data by using the probability of occurrence of the hydrogen-powered bicycle unit abnormal data in the real-time fuel cell system and energy storage system energy update using the on-board energy consumption monitoring interface used by the energy update use unit, and uses the control efficiency, initial information, and secondary information to calculate the new control efficiency of the hydrogen-powered bicycle unit abnormal data.

[0060] In this embodiment, the control efficiency of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update reflects the overall difficulty, operability and individual differences of the on-board energy consumption monitoring interface for real-time fuel cell system and energy storage system energy update to be calculated for each hydrogen power-assisted vehicle unit data control platform.
