Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
A first embodiment of the present invention provides a hydrogenation control method for a fuel cell vehicle, as shown in fig. 1, including:
s101, after a vehicle controller of a vehicle is awakened, a plurality of operating parameters of a hydrogen system of the vehicle are obtained, wherein the plurality of operating parameters comprise at least one of the current state of an air outlet cylinder valve of a hydrogen cylinder and the current state of a communication module, and the hydrogen system comprises the hydrogen cylinder and the communication module;
s102, judging each operating parameter in a plurality of operating parameters;
and S103, if each operating parameter meets the hydrogenation condition of the hydrogen system, the hydrogen bottle of the hydrogen system is hydrogenated through the hydrogenation port of the hydrogen system.
The vehicle of the present embodiment is a fuel cell vehicle, and is simply referred to as a vehicle.
The hydrogenation control method of the fuel cell vehicle of the embodiment is applied to a hydrogen system of the fuel cell vehicle. As shown in fig. 2, the Hydrogen system includes a Vehicle Control Unit (VCU) 201, a Hydrogen system controller (HMS) 202, a Hydrogen switch 203, a Hydrogen inlet 204, a Hydrogen bottle 205, a communication module 206 disposed on the Hydrogen inlet 204, and an instrument panel 207. The hydrogenation switch 203, the hydrogenation port 204, the hydrogen bottle 205, the communication module 206 and the vehicle controller 201 are all connected with the hydrogen system controller 202, and the vehicle controller 201 is further connected with the instrument panel 207.
Wherein, the hydrogenation switch 203 is used for realizing the on-off of the hydrogen system. The hydrogenation switch 203 is preferably a self-reset switch, and the self-reset switch originally carried by the vehicle can be used, so that the hydrogenation operation of a vehicle driver is facilitated, an additional hydrogenation switch is avoided, and a hydrogen system is simplified. The principle of the self-resetting switch is that the self-resetting switch automatically returns to the original position after the self-resetting switch is used. For example, assuming that the self-resetting switch is a self-resetting button, the self-resetting switch is in a pressed state when the self-resetting switch is pressed. When not pressed, the self-reset switch can automatically bounce and restore to the original position. The hydrogenation port 204 is used for transferring hydrogen gas added from the hydrogenation machine 208 through mechanical connection with the hydrogenation machine 208 of the hydrogenation station so that the hydrogenation machine 208 hydrogenates the hydrogen bottle 205. The communication module 206 is preferably an infrared communication module, which is used to communicate with the hydrogen system controller 202, and during the hydrogenation process of the vehicle, the hydrogen system controller 202 can send information such as hydrogenation flow rate and flow velocity to the hydrogenation machine 208 through the communication module 206. The hydrogen cylinder 205 is used to store hydrogen gas. The mouth of the hydrogen bottle 205 is provided with an inlet bottle valve for controlling hydrogen to enter the hydrogen bottle 205 and an outlet bottle valve for controlling hydrogen to exit from the hydrogen bottle 205. It should be noted that, during the process of controlling the hydrogen gas to be transferred from the hydrogenation unit 208 to the hydrogen bottle 205 through the inlet bottle valve, the outlet bottle valve is in a closed state to avoid hydrogen gas leakage. The dashboard 207 is used for displaying the state information of the hydrogen system in the hydrogenation process.
The following describes in detail the specific implementation steps of the hydrogenation control method for a fuel cell vehicle provided in this embodiment with reference to fig. 1 and fig. 2:
before waking up the vehicle controller 201 of the hydrogen system of the vehicle, it needs to confirm that the current gear of the vehicle is an OFF gear, the fuel cell system of the vehicle is completely purged, and the high voltage of the vehicle is powered OFF. If the fuel cell system does not complete purging, the entire vehicle high voltage is not powered down, indicating that the vehicle is unable to perform hydroprocessing.
After it is determined that the current gear of the vehicle is the OFF gear, the fuel cell system of the vehicle has finished purging, and the high voltage of the entire vehicle has been powered down, the entire vehicle controller 201 is awakened. The process of waking up the vehicle controller 201 is to wake up the hydrogen system controller 202 of the hydrogen system after detecting that the hydrogenation switch 203 of the hydrogen system is continuously in a closed state within a first preset time period; the hydrogen system controller 202 outputs a wake-up signal to wake up the vehicle controller 201. The first preset time period is set according to actual requirements, for example, the first preset time period is 3 seconds, 5 seconds or 7 seconds.
In a specific implementation process, when the driver presses the hydrogenation switch 203 for a first preset time period of 5 seconds, that is, the vehicle detects that the hydrogenation switch 203 is continuously in the closed state within the first preset time period of 5 seconds. After detecting that the hydrogenation switch 203 is continuously in a closed state within a first preset time, sending a pulse low level signal to the hydrogen system controller 202 through the hydrogenation switch 203, and waking up the hydrogen system controller 202. And continuously outputting a 12V high-level signal to the vehicle controller 201 through the hydrogen system controller 202 to wake up the vehicle controller 201.
In this embodiment, since the vehicle controller 201 does not support the pulse low level signal wake-up, and the hydrogen system controller 202 supports the pulse low level signal wake-up, the hydrogen system controller 202 is woken up by sending the pulse low level signal through the hydrogen adding switch 203, and then the hydrogen system controller 202 continuously sends the high level wake-up signal to wake-up the vehicle controller 201, so as to quickly and efficiently wake-up the hydrogen system of the fuel cell vehicle and the vehicle controller 201, thereby ensuring the wake-up efficiency of the vehicle controller 201 and the hydrogen system, improving the control efficiency of the fuel cell vehicle in the hydrogen adding process, and improving the hydrogenation experience of the user.
After waking up the vehicle control unit 201 of the vehicle, step S101 is executed, and after waking up the vehicle control unit of the vehicle, a plurality of operating parameters of a hydrogen system of the vehicle are obtained, where the plurality of operating parameters include at least one of a current state of an outlet cylinder valve of the hydrogen cylinder and a current state of the communication module, and the hydrogen system includes the hydrogen cylinder and the communication module.
Specifically, after waking up the hydrogen system controller 202 and the vehicle controller 201, the hydrogen system controller 202 may supply power to the communication module 206 disposed on the hydrogen inlet 204 and the outlet cylinder valve of the hydrogen cylinder 205, so that the communication module 206 can communicate with the hydrogen system controller 202, close the outlet cylinder valve, and detect a current state of the communication module 206 and/or a current state of the outlet cylinder valve of the hydrogen cylinder 205, that is, obtain a plurality of operating parameters of the hydrogen system, where the plurality of operating parameters include a current state of the communication module 206 and/or a current state of the outlet cylinder valve of the hydrogen cylinder 205.
Next, step S102 is executed to determine each of the plurality of operating parameters. Then, step S103 is executed, and if each of the operation parameters satisfies the hydrogenation condition of the hydrogen system, the hydrogen bottle 205 of the hydrogen system is hydrogenated through the hydrogenation port 204 of the hydrogen system. If one of the plurality of operating parameters does not satisfy the hydrogenation condition of the hydrogen system, a fault signal is sent to the dashboard 207 of the hydrogen system.
Specifically, since the plurality of operating parameters include the current state of the communication module 206 and/or the current state of the outlet valve of the hydrogen cylinder 205, the specific determination process for the plurality of operating parameters is divided into three cases. The first case is that the operation parameters include the current state of the communication module 206, and the judgment process of the current state of the communication module 206. The second case is that the operation parameters include the current state of the outlet cylinder valve of the hydrogen cylinder 205, and the judgment process of the current state of the outlet cylinder valve. The third situation is that the operation parameters include the current state of the communication module 206 and the current state of the outlet cylinder valve of the hydrogen cylinder 205, and the judgment process of the current state of the communication module 206 and the current state of the outlet cylinder valve.
For the first situation, after acquiring the current state of the communication module 206, it is determined whether the current state of the communication module 206 is in a communication state, where the communication state is a state in which normal communication can be performed between the communication module 206 and the hydrogen system controller 202. If the current state of the communication module 206 of the hydrogenation port 204 is in a communication state, which indicates that the operation parameters meet the hydrogenation conditions of the hydrogen system, the hydrogen bottle 205 is hydrogenated through the hydrogenation port 204. If the current state of the communication module 206 is not in the communication state, which indicates that the communication module 206 has a fault and the operation parameters do not satisfy the hydrogenation conditions of the hydrogen system, the hydrogen system controller 202 outputs a signal indicating that the communication module 206 has the fault to the dashboard 207 through the vehicle controller 201, so that the dashboard 207 displays an identifier indicating that the communication module 206 has the fault, and reminds a driver that the communication module 206 has the fault and the vehicle cannot perform the hydrogenation operation.
For the second case, after acquiring the current state of the outlet cylinder valve of the hydrogen cylinder 205, it is determined whether the current state of the outlet cylinder valve is in a closed state, where the closed state of the outlet cylinder valve is a state in which the outlet cylinder valve is closed. If the current state of the gas outlet cylinder valve of the hydrogen cylinder 205 is in a closed state, which indicates that the gas outlet cylinder valve is closed, and the operation parameters meet the hydrogenation conditions of the hydrogen system, the hydrogen cylinder 205 is hydrogenated through the hydrogenation port 204. If the current state of the outlet cylinder valve of the hydrogen cylinder 205 is not in a closed state, which indicates that the outlet cylinder valve has a fault and the operation parameters do not meet the hydrogenation conditions of the hydrogen system, the hydrogen system controller 202 outputs a signal indicating that the outlet cylinder valve has a fault to the instrument panel 207 through the vehicle controller 201, so that the instrument panel 207 displays an identifier indicating that the outlet cylinder valve has a fault, and the driver is reminded that the outlet cylinder valve has a fault and the vehicle cannot perform hydrogenation operation.
For the third situation, after the current state of the communication module 206 and the current state of the outlet valve of the hydrogen bottle 205 are obtained, the current state of the communication module 206 and the current state of the outlet valve of the hydrogen bottle 205 are determined, and for a specific determination process, please refer to the first situation and the second situation. If the current state of the communication module 206 of the hydrogen adding port 204 is in the communication state and the current state of the gas outlet bottle valve of the hydrogen bottle 205 is in the closed state, which indicates that each operating parameter meets the hydrogen adding condition of the hydrogen system, the hydrogen bottle 205 is added with hydrogen through the hydrogen adding port 204. If the current state of the communication module 206 of the hydrogen adding port 204 is not in the communication state, or the current state of the gas outlet cylinder valve of the hydrogen cylinder 205 is in the closed state, which indicates that the operation parameters do not meet the hydrogen adding conditions of the hydrogen system, a corresponding fault signal is sent to the instrument panel 207 of the hydrogen system.
It should be noted that, during the process of adding hydrogen to the hydrogen bottle 205 of the hydrogen system, the gas outlet bottle valve of the hydrogen bottle 205 is controlled to be continuously closed, so as to avoid hydrogen leakage during the hydrogenation process. If the outlet cylinder valve is not in a closed state continuously in the process of hydrogenating the hydrogen cylinder 205 of the hydrogen system, the hydrogen system controller 202 outputs a fault signal of the outlet cylinder valve to the instrument panel 207 through the vehicle controller 201, so that the instrument panel 207 displays a fault mark of the outlet cylinder valve, and a driver is reminded that the outlet cylinder valve is in fault and the vehicle cannot perform hydrogenation operation. Therefore, the present embodiment optimizes the safety monitoring mechanism of the hydrogen system, monitors the current state of the outlet cylinder valve of the hydrogen cylinder 205, and avoids the hydrogen system being damaged by the reverse flow of high-pressure hydrogen gas due to the unclosed outlet cylinder valve in the hydrogenation process.
In this embodiment, the current state of the communication module 206 and/or the current state of the outlet cylinder valve of the hydrogen cylinder 205 are determined to indicate whether each of a plurality of operating parameters of the hydrogen system satisfies the hydrogenation condition, so as to achieve a quick and efficient determination of the hydrogenation function. After each operation parameter of the hydrogen system is determined to meet the hydrogenation condition, the hydrogen bottle 205 is hydrogenated through the hydrogenation port 204, so that the bottle valve state of the hydrogen bottle 205 in the hydrogen system is monitored in real time, the efficient hydrogenation of the hydrogen system is guaranteed, and the control efficiency of the hydrogen system is improved.
After the hydrogen bottle 205 of the hydrogen system is hydrogenated through the hydrogenation port 204 of the hydrogen system, the hydrogenation of the hydrogen bottle 205 is stopped after the hydrogenation switch 203 is detected to be continuously in the closed state within the second preset time period. The second preset time period is set according to actual requirements, for example, the first preset time period is 3 seconds, 5 seconds or 7 seconds. The second preset duration may be the same as or different from the first preset duration.
Specifically, after the hydrogen bottle 205 of the hydrogen system is hydrogenated through the hydrogenation port 204 of the hydrogen system, that is, after the hydrogen in the hydrogen bottle 205 reaches the set threshold, the set threshold is set according to the actual requirement, and when the driver presses the hydrogenation switch 203 for a second preset time period of 5 seconds, that is, the vehicle detects that the hydrogenation switch 203 is continuously in the closed state within the second preset time period of 5 seconds. After detecting that the hydrogenation switch 203 is continuously in the closed state within the second preset time, the hydrogen system controller 202 sends a hydrogenation stopping signal to the vehicle controller 201, controls the vehicle controller 201 to be in the dormant state, and stops hydrogenation on the hydrogen bottle 205.
One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:
in this embodiment, the vehicle controller of the vehicle is awakened first, so that the hydrogen system and the vehicle controller of the fuel cell vehicle are awakened quickly and efficiently during the hydrogenation process, and the control efficiency of the hydrogen system is improved. After a vehicle controller of a vehicle is awakened, a plurality of operating parameters of a hydrogen system of the vehicle are obtained, wherein the plurality of operating parameters comprise at least one of the current state of an air outlet cylinder valve of a hydrogen cylinder and the current state of a communication module, and the hydrogen system comprises the hydrogen cylinder and the communication module; and then each operating parameter in the plurality of operating parameters is judged. Here, whether each of the plurality of operating parameters of the hydrogen system satisfies the hydrogenation condition is indicated by judging the current state of the communication module and/or the current state of the outlet cylinder valve of the hydrogen cylinder, so that the hydrogenation function is judged quickly and efficiently, and the judgment efficiency of the hydrogenation condition of the hydrogen system is improved. If each operating parameter meets the hydrogenation condition of the hydrogen system, the hydrogen bottle of the hydrogen system is hydrogenated through the hydrogenation port of the hydrogen system, so that the bottle valve state of the hydrogen bottle in the hydrogen system is monitored in real time, the efficient hydrogenation of the hydrogen system is guaranteed, and the control efficiency of the hydrogen system is improved.
