The cylinder valve is connected with one end of the mechanical pressure reducing valve through a hydrogen supply pipeline; the other end of the mechanical pressure reducing valve is connected with the hydrogen fuel cell engine;
the pressure sensors are arranged at two ends of the mechanical pressure reducing valve;
in the embodiment of the application, the number of the pressure sensors is two, the pressure sensors are respectively a high-pressure sensor and a low-pressure sensor, the high-pressure sensor is installed at one end, close to the cylinder valve, of the mechanical pressure reducing valve, and the low-pressure sensor is installed at one end, close to the front cabin of the hydrogen fuel cell engine, of the mechanical pressure reducing valve.
The temperature sensor and the pressure sensor are electrically connected with the hydrogen supply controller HCU;
the hydrogen supply controller HCU is used for controlling the opening and closing of the cylinder valve; (in practice, the hydrogen supply controller HCU can also control a mechanical pressure reducing valve and an electric control proportional valve, which is not the core content of the application and is not explained here)
The hydrogen supply controller is connected with the hydrogen fuel cell engine controller FCU through a CAN bus.
The system also comprises an electric control proportional valve; and one end of the electric control proportional valve is connected with the mechanical pressure reducing valve through a hydrogen supply pipeline, and the other end of the electric control proportional valve is connected with the hydrogen fuel cell engine.
The system further includes a hydrogen concentration sensor; the hydrogen concentration sensor is arranged in the hydrogen storage bin and is electrically connected with the hydrogen supply controller. In this application, the hydrogen concentration sensors are 3, two are installed in the hydrogen storage bin, and the other one is installed in the front cabin of the hydrogen fuel cell engine.
Input signals of the whole hydrogen supply control system comprise analog quantity input signals and CAN bus input signals;
the analog input signal comprises: a temperature sensor input signal, a pressure sensor input signal, and a hydrogen concentration sensor input signal; the CAN bus input signals comprise: the FCU sends a control mode signal, a cylinder valve total enabling signal, each cylinder valve enabling signal and an air bag control unit ACU sends a collision acceleration signal;
a hydrogen supply control method for a fuel cell hydrogen energy automobile specifically comprises the following steps:
s101: the hydrogen supply controller HCU judges the fault state of the hydrogen supply control system according to the sensing data of the temperature sensor, the pressure sensor and the hydrogen concentration sensor;
s102: the hydrogen fuel cell start-up controller FCU sends a control command to the hydrogen supply controller HCU according to the fault state of the hydrogen supply control system;
s103: and the hydrogen supply controller HCU controls the bottle valve according to the control instruction, so that the hydrogen supply safety of the hydrogen supply system is ensured.
In the examples of the present application, the above steps are described in detail as follows:
the failure judgment of the hydrogen supply system is complex, and the mode control of the hydrogen supply system only relates to the condition whether the HCU failure level is equal to 3 or not.
Referring to fig. 2, fig. 2 is a flow chart of a failure determination of a hydrogen supply system.
Firstly, after the HCU controller is electrified, the initialization is completed, and the self-checking is carried out:
the cylinder valve is an electromagnetic valve, and a driving pin of the cylinder valve has a circuit diagnosis function and judges whether the 4 cylinder valve electromagnetic valve loops are open or short-circuited (short-circuited to ground and short-circuited to a power supply). If the circuit fails, the HCU failure level is 3;
and if not, continuously judging whether the acquisition circuit of the sensor has faults or not, wherein the acquisition circuit of the sensor comprises a high-pressure sensor and a hydrogen concentration sensor, and paying attention to the fact that the fault grade of the circuit of the temperature sensor is 2. If the signal loops of the pressure sensor and the concentration sensor have no open circuit or short circuit fault, the HCU fault level is 3;
otherwise, the signal rationality fault is continuously judged, wherein the fault comprises that the pressure of a high-pressure pipeline of the hydrogen bottle is too high or too low, the medium-pressure pipeline is too high or too low, the hydrogen leakage concentration is too high, and the temperature in the hydrogen bottle is too high. If the fault is reported, the fault level of the HCU is 3;
if not, continuously judging communication faults including whether the message between the HCU and the FCU and the ACU is lost or communication overtime faults, and if the faults are reported, judging the HCU fault level to be 3;
otherwise, the HCU fault level is less than 3, and the specific numerical values are classified according to the fault diagnosis level of the hydrogen supply system, which is not described in this patent. When the HCU fault level is 3, the hydrogen system is seriously failed.
When the HCU determines the fault level of the system, the HCU can respond to the control of the cylinder valve of the hydrogen storage tank in different modes.
In step S102, the control command comprises a control mode and enabling signals of all cylinder valves; the control modes include an automatic mode, a manual mode, and a maintenance mode.
In an automatic mode, the HCU fault level is less than 3, and 4 cylinder valves can be controlled to act simultaneously through a main switch instruction sent by an FCU message. The mode belongs to a normal working state, and the control time sequence among the cylinder valves is ensured to be consistent. If the hydrogen system sends a serious failure, the bottle opening valve is forbidden for safety first.
In a manual mode, when the HCU fault level is less than 3, 4 cylinder valves are controlled independently; the master switch command is invalid in 13. The hydrogen system sends a catastrophic failure to safely first inhibit opening of any one of the cylinder valves. The cylinder valve is more flexible to control in the manual mode, a certain hydrogen storage tank can be independently started, and if the capacity of the cylinder valve electromagnetic valve driving chip is limited, a certain cylinder valve can be independently controlled, so that the impact of driving current is reduced.
In the maintenance mode, the 4 cylinder valves are controllable whether or not the hydrogen supply system is transmitting a catastrophic failure. When a circuit fault occurs to a certain cylinder valve electromagnetic valve, an engineer can skip the limitation of the fault grade in the maintenance under the mode and test the opening and closing of any cylinder valve. This is very important for the engineer to test and repair, and in this mode, the HCU controller program or data is not required to be changed, and the diagnostic device requests the corresponding mode to enter the repair state.
The control of the hydrogen storage tank bottle valves in the three modes greatly increases the use safety, flexibility and maintenance convenience of the hydrogen supply system.
The beneficial effects provided by the invention are as follows: the fault detection method and the multi-mode control method for the hydrogen supply system are provided, and the hydrogen supply safety of the fuel cell hydrogen energy automobile is greatly improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
