When the fuel cell stops generating electricity, part of the water will remain inside the fuel cell and in the peripheral piping. When the vehicle is in a low temperature environment, water remaining in the fuel cell and in the peripheral piping may freeze, thereby affecting the normal use of the fuel cell. The park scavenging is generally performed when the fuel cell stops generating electricity to remove water remaining in the fuel cell and in the peripheral piping.
In the vehicle parked state, when the vehicle is charged with the charging stake, if it is detected that the user performs a preset operation, the control mode of the vehicle may be configured as a my room (my room) mode. In my room mode, the control device prohibits the vehicle from traveling and allows the operation of some auxiliary devices (low-voltage auxiliary load, high-voltage auxiliary load, etc.). Allowing the user to rest in the vehicle while operating the air conditioner, listen to music by operating the audio device, use by connecting the electrical device brought by the user to the in-vehicle outlet, and the like.

Detailed Description
As described above, in the prior art, when charging a vehicle using a charging pile, if parking scavenging of a fuel cell is being performed, the parking scavenging of the fuel cell is interrupted when a user enters the vehicle and enters my room mode. If the parking scavenging is interrupted, the water remaining in the fuel cell and in the peripheral pipeline is not completely scavenged, and the residual water which is not scavenged may still freeze, thereby affecting the normal use of the fuel cell.
In order to solve the above problems, in the embodiment of the present invention, when parking scavenging of the fuel cell is performed, a gear state of the ignition switch is detected, and when it is detected that the ignition switch is in IG-ON gear and enters into my room mode, parking scavenging of the fuel cell is continuously performed, so that a user can use the my rom mode of the vehicle without interrupting the parking scavenging of the fuel cell, and the my rom mode of the vehicle can be used while the parking scavenging of the fuel cell is performed.
In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the following detailed description of the embodiments of the present invention refers to the accompanying drawings.
The embodiment of the invention provides a vehicle control method which can be used for controlling parking scavenging of a fuel cell. Referring to fig. 1, a flowchart of a vehicle control method according to an embodiment of the present invention is provided, and the vehicle control method may include the steps of:
step S11 detects a gear state of an ignition switch when parking scavenging of the fuel cell is performed.
In practice, a Fuel Cell (FC) generates water during power generation. When the fuel cell stops generating electricity, water remains in the fuel cell, in the pipes, in the water pump, and other components. In a low-temperature environment, in order to avoid freezing of residual water in the fuel cell, a pipeline, a water pump and the like, normal use of the fuel cell is affected. The fuel cell is typically park scavenged to remove residual water.
When the fuel cell stops generating electricity, the ambient temperature at which the vehicle is located may be detected, and when the ambient temperature at which the vehicle is located is detected to be lower than the set temperature and the fuel cell stops generating electricity, parking scavenging of the fuel cell may be performed.
In an implementation, the gas supply may be controlled to supply gas to the fuel cell, the supplied gas being swept across the fuel cell, a pipe, etc., to blow dry the residual water. A battery in the vehicle may be employed to power the gas supply.
In an embodiment of the present invention, the gas supply part may be an Air Compressor (ACP). The air compressor may also provide an oxidizing gas (e.g., air) to the fuel cell when the fuel cell is generating electricity. Specifically, the gas is supplied to the cathode of the fuel cell.
The various components of the fuel cell vehicle each have a corresponding electronic controller unit (Electronic Control Unit, ECU) for respective operation and control. For example, an ECU (FC-ECU) for controlling a fuel cell, an ECU (HV-ECU) for controlling the whole vehicle, and an ECU (battery ECU) for controlling a battery. When the FC-ECU detects that FC power generation is stopped, a wake-up signal may be sent to the HV-ECU to wake up the HV-ECU. The HV-ECU may acquire the temperature of the environment in which the vehicle is located, detected by the temperature detection device. After the HV-ECU is awakened by the TC-ECU, the battery ECU may be awakened. After the battery ECU wakes up, the battery may be controlled to supply power to the ACP. HV-ECU controls ACP start, which supplies gas to FC.
In a specific implementation, the gear state of the ignition switch may be detected when the parking scavenging of the fuel cell is performed. The ignition switch may include a number of different gear positions, typically including a LOCK gear, an Accessory (ACC) gear, an ignition (IG-ON) gear, and a start (ST-ON) gear.
LOCK gear: a "LOCK" identification is typically employed on the vehicle. When the vehicle is in LOCK gear, except the anti-theft system and the small lamp in the vehicle, the power supply of the whole vehicle is cut off, the circuit is completely closed, and the steering wheel is locked.
ACC gear: for accessory power-up gear, an "ACC" identification is typically employed on the vehicle. When the ACC gear is set, the accessory power circuit is turned on, and equipment such as a radio, a car lamp and the like can be used, but an air conditioner cannot be used.
IG-ON gear: typically, an "ON" sign is employed ON the vehicle. When the vehicle is in the IG-ON gear, all circuits of the whole vehicle are in a working state, and other basic devices are all ON, so that the steering wheel can be unlocked, and an air conditioner can be used.
ST-ON gear: typically, a "ST" or "START" identification is employed on the vehicle. When in ST-ON gear, the fuel cell is started to generate electricity.
And step S12, when the ignition switch is detected to be in the IG-ON gear and enters the My room mode, the parking scavenging of the fuel cell is continuously executed.
In an implementation, the my room mode refers to a mode in which a control mode of the vehicle may be configured as the my room mode when a user performs a preset operation while charging a storage battery on the vehicle with external power (e.g., a charging stake). In my room mode, the control device prohibits the vehicle from traveling and allows the operation of some auxiliary devices (low-voltage auxiliary load, high-voltage auxiliary load, etc.). Allowing air conditioning or audio to be used during charging. The preset operation performed by the user may be: the vehicle key is inserted into the ignition switch, and the shift position of the ignition switch is adjusted to the IG-ON shift position.
Specifically, whether to charge the vehicle by the charging pile can be determined by detecting the gun inserting action or the power connection condition of the charging interface, and whether to enter the my rom mode can be determined by combining the gear switch state of the ignition switch.
It has been found that the reason why the parking scavenging of the fuel cell being performed is interrupted when entering the my room mode in the prior art is that the user needs to adjust the shift position of the ignition switch to the IG-ON range when entering the my room mode. However, when the state of the ignition switch is in the IG-ON range, the default vehicle is ignited, a preparation phase for running the vehicle is entered, a low-pressure processing operation before running the vehicle is executed, preparation for running the vehicle is made, and the parking scavenging of the fuel cell is terminated. The low-pressure processing operation may include, among other things, a status self-check of some ECUs in the vehicle, etc. At this time, although the shift position of the ignition switch is adjusted to the IG-ON range, it may be that only the my room mode is entered and there is no intention of the vehicle to travel, so that it is impossible to determine whether the vehicle has a intention of traveling based ON the IG-ON range of the ignition switch. In order to ensure normal progress of the park scavenging of the fuel cell, in the embodiment of the invention, when the ignition switch is detected to be in the IG-ON range and enters the my room mode, the park scavenging of the fuel cell is continued to be performed.
As is clear from the above, when the parking scavenging of the fuel cell is performed, the gear state of the ignition switch is detected, and when the ignition switch is detected to be in the IG-ON gear and enter the my room mode, the parking scavenging of the fuel cell is continuously performed, so that the user can use the my rom mode of the vehicle without interrupting the parking scavenging of the fuel cell, and the my rom mode of the vehicle can be used while the parking scavenging of the fuel cell is realized.
In a specific implementation, during the parking scavenging of the fuel cell, abnormal termination of the scavenging may occur. For example, when the parking scavenging is not completed, the intention of the vehicle to travel is detected, and the execution of the parking scavenging of the fuel cell is stopped. For another example, the park scavenging is actively terminated by the user for a set period of time. If the scavenging abnormal termination occurs, water remains in the fuel cell, the pipe, and the like, and the low temperature freezing may occur.
In order to solve the above-mentioned problem, in the embodiment of the present invention, when the abnormal termination of the parking scavenging of the fuel cell is detected, counting time from the abnormal termination of the scavenging, and after reaching the preset second period of time, judging whether the scavenging start condition is satisfied; when the scavenging start condition is satisfied, parking scavenging of the fuel cell is performed to remove residual water in the fuel cell, the pipe, and the like.
Wherein the scavenging start condition may include the temperature being lower than the set temperature and the fuel cell stopping power generation.
In implementations, the second period of time may be related to an ambient temperature at which the vehicle is at the time the scavenging abnormal termination. The second period may be shorter when the ambient temperature to which the vehicle is exposed is lower when the scavenging abnormal is terminated. The method and the device can realize the parking scavenging of the fuel cell in a short time, so as to avoid the influence of the freezing of residual water on the normal use of the fuel cell. It is understood that the second time period may also be configured as a fixed time period, such as three minutes, five minutes, ten minutes, or other values.
In a specific implementation, it is also possible to detect in real time whether the scavenging termination condition is satisfied when the parking scavenging of the fuel cell is performed. The scavenging end condition may include the scavenging period reaching a set first period, or the detection of a willingness of the vehicle to travel.
In the specific implementation, the scavenging period may be determined based on the power generation period of the fuel cell or a predicted amount of residual water in the fuel cell, the flow rate of the gas supplied from the gas supply portion, or the like. It is to be understood that the scavenging time period may also be configured as a fixed time period.
In implementations, detection of a willingness to travel of the vehicle may be detection of an ignition switch being ST-ON.
In a specific implementation, when it is detected that the scavenging termination condition is satisfied, execution of the parking scavenging of the fuel cell is stopped.
In a specific implementation, when it is detected that the ignition switch is ON ST-ON, it may be determined that a vehicle travel intention is detected, execution of the parking scavenging of the fuel cell is stopped, and preparation before the vehicle travel is performed. Among them, the preparation before the vehicle runs may include a low-pressure processing operation, a high-pressure processing operation, and the like. The high-voltage processing operation may include a main relay actuation to connect the high-voltage power consumption component with the high-voltage battery, etc.
In a specific implementation, in order to facilitate the user to intuitively acquire the parking scavenging condition of the current fuel cell, when the parking scavenging of the fuel cell is performed, the parking scavenging prompt information may be output.
The parking scavenging prompt information can be the corresponding indication lamp on the instrument panel to light or flash. The corresponding parking scavenging prompt identification can be output on the instrument panel. The parking scavenging prompt message can also be a sound prompt.
The embodiment of the invention also provides a vehicle control device. Referring to fig. 2, a schematic configuration diagram of a vehicle control apparatus in an embodiment of the invention is given. The vehicle control device 20 may include:
