Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, the safety result is not accurate by judging the hydrogenation safety of the hydrogen storage system; firstly, the hydrogen storage system has some limiting factors, so that the situation of hydrogen leakage cannot be fed back quickly; secondly, vehicle high voltage detection tends to miss high voltage signal detection in the fuel cell; in addition, a data signal that can truly characterize the stationary state of the vehicle is not acquired to determine the vehicle safety. On the basis, the safety and reliability of the traditional hydrogen storage control method are not high.
Based on the above, the embodiment of the invention provides a hydrogenation control method, a hydrogenation control device and electronic equipment for a fuel cell automobile, which are used for relieving the technical problem of low safety in the hydrogenation control process of the automobile.
For the convenience of understanding the present embodiment, the hydrogenation control method of the fuel cell automobile disclosed in the embodiment of the present invention is first described in detail, and the method may be applied to intelligent control devices such as a vehicle controller, a hydrogen storage controller, a battery management system, and the like.
Fig. 1 is a flowchart of a hydrogenation control method of a fuel cell automobile according to an embodiment of the present invention.
Referring to fig. 1, the method may include the steps of:
step S102, determining the hydrogenation requirement of the current fuel cell automobile according to a control instruction for the hydrogen storage system.
The user can trigger the control to request hydrogenation through controls such as a hydrogenation prompt button and the like when the hydrogenation requirement exists, or send a hydrogen residual shortage signal or a hydrogenation request signal to the whole vehicle controller VCU when the hydrogen residual of the hydrogen storage system is insufficient. The control instruction can be understood as a control instruction for touch triggering of the prompt button or a control instruction for the hydrogen storage system sent to the VCU, so that the controller can know the hydrogenation requirement of the hydrogen storage system based on the control instruction.
Step S104, judging whether the hydrogen concentration, the hydrogen temperature and the hydrogen pressure at the two ends of the pressure reducing valve of the hydrogen storage system meet the preset hydrogenation conditions.
The real hydrogenation safety of the hydrogen storage system is represented by the hydrogen concentration, the hydrogen temperature and the hydrogen pressure at the two ends of the pressure reducing valve of the hydrogen storage system, and whether the hydrogen storage system meets preset hydrogenation conditions is judged.
And step S106, if the current fuel cell automobile is satisfied, controlling the current fuel cell automobile to carry out hydrogenation operation.
In a practical preferred embodiment, according to a control instruction for the hydrogen storage system, obtaining the hydrogenation requirement of the hydrogen storage system, determining the real hydrogenation safety of the hydrogen storage system based on the hydrogen concentration and the hydrogen temperature of the hydrogen storage system and the hydrogen pressure at two ends of the pressure reducing valve, comparing the real hydrogenation safety with preset hydrogenation conditions, and judging whether the real hydrogenation safety is met; and under the condition that the hydrogenation control is satisfied, controlling the fuel cell automobile to hydrogenate so as to ensure the safety and reliability of hydrogenation control.
In some embodiments, to ensure hydrogenation safety, the method further comprises, prior to step S102:
step 1.1), initializing the hydrogen storage system and judging whether the hydrogen storage system is safe or not.
The current fuel cell automobile is powered on, the automobile is awakened by a key power K15 or a K15 in the awakening power, and an electric control part of the hydrogen storage system is initialized in sequence to check whether the hydrogen storage system is safe or not.
Step 1.2), if the hydrogen storage system is safe, step S102 of determining the current hydrogen demand of the fuel cell vehicle is performed.
It should be noted that, if the hydrogen storage system is safe, the system enters a standby state, and a subsequent step of determining the hydrogenation requirement of the current fuel cell automobile can be executed; if the hydrogen storage system is abnormal, namely, the hydrogen storage system is controlled to enter a fault mode, and the hydrogen storage system cannot be subjected to hydrogenation operation in the fault mode.
In some embodiments, by monitoring the hydrogen concentration, hydrogen pressure and hydrogen temperature on the hydrogen storage system, whether hydrogenation can be performed is determined according to the hydrogen real data; illustratively, step S104 may be further implemented by the steps of:
Step 2.1), judging whether the hydrogen concentration of the hydrogen storage system exceeds a preset concentration threshold value, whether the hydrogen temperature exceeds a preset temperature threshold value and whether the hydrogen pressure at two ends of the pressure reducing valve exceeds a preset pressure threshold value.
As shown in fig. 2, the hydrogen storage system includes three cylinders 1, and the number of cylinders 1 in fig. 2 is only one example and is not limited thereto. Each cylinder 1 has a cylinder valve (On TANK VALVE, OTV) 2, and each cylinder 1 is provided with a temperature sensor 3 for measuring the temperature of the hydrogen gas in each cylinder 1, and a pressure sensor 4 for detecting high pressure is provided On the front section high pressure line of the pressure reducing valve 5, while the rear end of the pressure reducing valve has a pressure sensor (not shown in fig. 2) for detecting medium pressure to detect the pressure at the rear end of the pressure reducing valve. In addition, according to the actual situation, a plurality of hydrogen sensors are arranged to detect the hydrogen concentration, and an electronic control unit (ECU of the fuel vehicle) 6 is used to read the sensors and control the respective cylinder valves 2 to determine whether the hydrogen concentration, the hydrogen temperature, and the hydrogen pressure exceed the respective set threshold values.
It should be noted that, the hydrogen storage system can detect whether the data actually reflecting the safety of the system, such as the high pressure, the medium pressure, the hydrogen temperature in the hydrogen storage bottle, the hydrogen concentration and the like of the hydrogen storage system exceeds the standard through the high pressure sensor, the medium pressure sensor, the temperature sensor and the hydrogen concentration sensor so as to judge whether the hydrogen storage system is safe.
And 2.2) if the pressure change rate of the hydrogen in the high-pressure pipeline at one side of the pressure reducing valve does not exceed the preset pressure change rate threshold value, judging whether the pressure change rate of the hydrogen in the high-pressure pipeline at one side of the pressure reducing valve exceeds the preset pressure change rate threshold value.
In order to further improve the safety of the hydrogen storage system, the hydrogen high-pressure change rate of the high-pressure pipeline is detected on the basis of the step 2.1) so as to detect whether the hydrogen storage system has micro leakage or not, solve the problem that a hydrogen sensor cannot detect the hydrogen storage system, and ensure the authenticity of data. For example, if the pressure drop of the high-pressure in the high-pressure pipeline is P0 within a certain time period t0, the pressure drop P0 is smaller than the preset pressure drop threshold, the high-pressure pipeline is safe, and the hydrogen storage system is safe.
Step 2.3), if the hydrogen storage conditions are not exceeded, the hydrogen storage system meets the preset hydrogenation conditions.
If the hydrogen storage safety is exceeded, the hydrogen storage system does not have hydrogenation safety, and the hydrogenation operation is stopped.
In some embodiments, the method further includes, before step S106, further ensuring hydrogenation safety of the hydrogen storage system by determining whether the vehicle is in a low-high pressure state:
Step 3.1), judging whether the power battery and the high-voltage relay of the fuel battery of the current fuel battery automobile are in an on state or not, and judging whether the output voltage of the high-voltage ends of the power battery and the fuel battery exceeds a voltage threshold value or not.
If the high-voltage relays of the power battery and the fuel battery are in an on state, whether the high-voltage signals output by the high-voltage ends of the power battery and the fuel battery are smaller than a preset voltage threshold value is judged, and if the high-voltage signals are smaller than the preset voltage threshold value, the vehicle is in a low-high-voltage state.
Step 3.2), if both the hydrogen storage conditions are met, the hydrogen storage system meets the preset hydrogenation conditions. If there is an unsatisfied condition, the hydrogen storage system is still not capable of hydroprocessing.
It can be understood that when the hydrogen storage system meets the hydrogenation safety requirement, the vehicle is in a low-high-pressure state, so that the hydrogenation safety of the fuel cell automobile can be further ensured.
As an alternative embodiment, the hydrogenation safety of the fuel cell automobile can also be judged by checking whether the automobile has an element action which is easy to cause static electricity or electric spark; if the vehicle has such an element action, the fuel automobile does not have hydrogenation safety.
In some embodiments, it is further determined whether the vehicle is at a lower standstill by data truly reflecting the state of the vehicle, so as to further ensure the hydrogenation safety of the hydrogen storage system, and before step S106, the method further includes:
And 4.1), judging whether the current fuel cell automobile is in a parking gear or not, and judging whether the speed of the current fuel cell automobile does not exceed a speed threshold value or not.
The method comprises the steps of checking whether a vehicle enters a parking state or a braking state, namely checking whether the vehicle is in a parking gear or checking whether the vehicle speed of the vehicle is smaller than a required vehicle speed, and judging whether the vehicle is in a safety state or not by detecting the wheel speed of the wheels.
Here, if the above-described step 4.1) has an unsatisfied condition, it is known that the vehicle does not satisfy the hydrogenation safety condition without executing the subsequent step.
Step 4.2), if both the signals are satisfied, judging whether the collision signal of the current fuel cell automobile is triggered.
In order to further ensure the reliability of the hydrogenation safety judgment, besides the judgment of the gear and the vehicle speed, the true stationary state of the vehicle is also shown by a vehicle collision signal, such as a signal generated by the actions of collision, movement or gear shifting of the vehicle.
Step 4.3), if not triggered, the hydrogen storage system meets preset hydrogenation conditions. If the collision signal exists, the hydrogen storage system can not be subjected to hydrogenation operation.
If the collision signal of the vehicle is not triggered, the collision signal sensor of the vehicle is not set, or the sensor does not collect the collision signal, the vehicle is in a safe state.
It can be understood that when the hydrogen storage system meets the hydrogenation safety requirement and the vehicle is in a low-high-pressure state, the vehicle is still in a static state, so that the hydrogenation safety of the fuel cell automobile can be further ensured.
In some embodiments, the hydrogenation safety of the hydrogen storage system is further ensured by judging the state of the hydrogenation cover, and before step S106, the method further includes:
And 5.1), judging whether the hydrogenation cover of the current fuel cell automobile can be unlocked within a preset time.
It can be understood that if the hydrogenation cover is unlocked, the hydrogenation cover needs to be locked to enable the vehicle to be in a safe state, or whether the hydrogenation cover is unlocked within a specified time is judged, if yes, the hydrogenation cover has the ability of being unlocked within a preset time; if not, an unlocking timeout or unlocking failure fault alarm is sent out.
Step 5.2), if yes (no alarm exists), the hydrogen storage system meets the preset hydrogenation conditions, and the hydrogenation cover is controlled to be unlocked before hydrogenation. If not, the hydrogen storage system cannot be subjected to hydrogenation operation.
It can be understood that when the hydrogen storage system meets the requirements of hydrogenation safety and the vehicle is in a low-high-pressure state and a static state, the hydrogenation cover also has unlocking capability in a preset time, so that the hydrogenation safety of the fuel cell automobile can be further ensured.
In some embodiments, the hydrogen safety of the vehicle during the hydrogen adding process may be monitored by the hydrogen adding station and the vehicle simultaneously to ensure the hydrogen safety of the vehicle and the hydrogen adding station, and step S106 includes:
step 6.1), controlling the hydrogenation gun of the current fuel cell automobile to be in physical connection with the hydrogenation port.
And 6.2) judging whether the current fuel cell automobile establishes communication with the hydrogen adding station or not.
And 6.3) if not, the hydrogen adding station performs no-communication hydrogen adding with the current fuel cell automobile.
The hydrogen storage controller of the hydrogen storage system detects signals of hydrogen pressure, temperature and hydrogen concentration in a gas cylinder of the vehicle hydrogen storage system, and if the signals exceed the standard, the hydrogen storage controller enters a fault state and feeds back to an upper computer, such as a driving computer, a man-machine interaction system and the like; if the standard is not exceeded, continuing the communication-free hydrogenation.
And 6.4), if so, the hydrogen adding station carries out communication hydrogen adding with the current fuel cell automobile.
The hydrogen storage controller of the hydrogen storage system detects hydrogen pressure, temperature and hydrogen concentration signals in a gas cylinder of the vehicle hydrogen storage system and sends the signals to the hydrogen adding station, and if the signals exceed the standard, the hydrogen storage controller enters a fault state and feeds the fault state back to the upper computer; meanwhile, if the hydrogenation station detects out of standard, the hydrogenation station sends out a communication abnormal alarm or switches to a fault mode so as to finish hydrogenation; controlling the hydrogenation gun to be pulled out, cutting off communication, and falling the hydrogenation cover off the lock; if the data do not exceed the standard, continuing to carry out communication hydrogenation; the hydrogenation station also continues to execute the hydrogenation program until the hydrogenation is finished, and the hydrogenation gun is controlled to be pulled out, and the hydrogenation cover is locked.
In the actual application process, the electronic control unit VCU of the electric control vehicle can check whether the hydrogenation cover is successfully locked, and if not, the locking action is continuously executed; if successful, the VCU sends a hydrogenation stopping request; the hydrogen storage controller receives a hydrogenation stopping request to jump from a hydrogenation state to a standby state, and if the state jump is unsuccessful, the hydrogen storage controller enters a fault state and sends the fault state to the upper computer; if the state jump is successful, the hydrogen storage controller is in a standby state; and ending the hydrogenation flow.
