Detailed Description
The embodiment of the application solves the technical problem that wind resistance of the whole vehicle during running can not be reduced while active air inlet grille heat dissipation is ensured in the prior art by providing the grille control method, the grille control device, the grille control equipment and the grille control medium.
The technical scheme of the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
a method of grid control, the method comprising: when a whole car key start signal of the fuel cell car is detected, acquiring the hydrogen concentration of a first front cabin of the fuel cell car; when the first front cabin hydrogen concentration is smaller than a first preset hydrogen concentration, controlling a target grille of the fuel cell automobile to be converted from an open state to a closed state, and acquiring a target refrigerant temperature of a target radiator corresponding to the target grille; when the target refrigerant temperature is greater than a preset temperature threshold, the target grille is controlled to be switched from a closed state to an open state, and the opening angle of the target grille is determined according to the target refrigerant temperature.
According to the method, when the vehicle is started, whether the hydrogen concentration of the front cabin is smaller than the first preset hydrogen concentration is detected, whether the vehicle is in a hydrogen leakage state can be judged, the fuel cell automobile can be prevented from being started in the hydrogen leakage state, and the occurrence probability of safety accidents is further reduced. Further, when the fuel cell vehicle does not leak hydrogen, the control target grille is switched from the open state to the closed state to more rapidly increase the refrigerant temperature, so that the vehicle can be started quickly. And the temperature of the target refrigerant is monitored, and the opening angle of the target grille is determined according to the temperature of the target refrigerant, so that the opening angle of the target grille can be reduced as much as possible while the heat dissipation of a galvanic pile is met, the wind resistance of the whole automobile is reduced as much as possible, and the economical efficiency of the fuel cell automobile is improved.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The present embodiment provides a grid control method as shown in fig. 1, which is applied to a controller of a fuel cell system, and includes steps S11 to S13.
Step S11, when a whole car key start signal of the fuel cell car is detected, acquiring the hydrogen concentration of a first front cabin of the fuel cell car;
Step S12, when the first front cabin hydrogen concentration is smaller than a first preset hydrogen concentration, controlling a target grille of the fuel cell automobile to be switched from an open state to a closed state, and acquiring a target refrigerant temperature of a target radiator corresponding to the target grille;
And S13, when the target refrigerant temperature is greater than a preset temperature threshold, controlling the target grille to be switched from a closed state to an open state, and determining the opening angle of the target grille according to the target refrigerant temperature.
With respect to step S11, when the entire vehicle key start signal of the fuel cell vehicle is detected, the first front cabin hydrogen concentration of the fuel cell vehicle is acquired.
Compared to conventional electric vehicles and fuel-powered vehicles, fuel hydrogen of fuel cell vehicles (e.g., hydrogen fuel cell vehicles) may leak, and thus there is a safety problem. Therefore, the hydrogen concentration of the fuel cell vehicle needs to be detected and judged before the fuel cell vehicle is started. For example, in the case of leakage of hydrogen gas, the engine front compartment of the fuel cell vehicle is liable to accumulate the leaked hydrogen gas, and therefore, the first front compartment hydrogen concentration of the fuel cell vehicle can be detected by the front compartment hydrogen concentration sensor.
Judging whether the first front cabin hydrogen concentration is smaller than a first preset hydrogen concentration or not, wherein the first preset hydrogen concentration can be set according to specific conditions.
When the first front cabin hydrogen concentration is greater than or equal to the first preset hydrogen concentration, the hydrogen leakage is generated, and if the automobile is started continuously, safety accidents are easy to occur, so that the continuous starting of the automobile needs to be stopped, and an alarm prompt is sent out to reduce the possibility of hydrogen explosion.
When the first front compartment hydrogen concentration is smaller than the first preset hydrogen concentration, which means that no hydrogen leakage occurs in the automobile, the automobile can be continuously started, and then step S12 is continuously performed.
With respect to step S12, when the first front compartment hydrogen concentration is smaller than the first preset hydrogen concentration, the target grille of the fuel cell vehicle is controlled to switch from the open state to the closed state, and the target refrigerant temperature of the target radiator corresponding to the target grille is obtained.
This embodiment will be described with respect to the grille and front compartment system components shown in fig. 2.
In fig. 2, there are included grids 1,2, 3, radiators 4, 5, 6, cooling fans 40, 50, 60, a condenser 7 and a fuel cell stack 8. The fuel cell stack 8 belongs to a heat generating source, and the grids 1,2 and 3 are distributed outside the fuel cell stack 8 to provide air for heat dissipation for the fuel cell stack 8, wherein the grids 2 and 3 are positioned on two sides of the grid 1. In order to better dissipate heat, a cooling fan 40, a radiator 4 and a condenser 7 (used for exchanging heat between the high-temperature and high-pressure refrigerant and air in the air conditioning system and changing the high-temperature and high-pressure refrigerant into a low-temperature and high-pressure refrigerant) are also arranged between the fuel cell stack 8 and the grid 1; a cooling fan 60 and a radiator 6 are also provided between the fuel cell stack 8 and the grid 2; a cooling fan 50 and a radiator 5 are also provided between the fuel cell stack 8 and the grid 3.
Returning to step S12, when the first front compartment hydrogen concentration is less than the first preset hydrogen concentration, the vehicle may continue to start, and the target grid of the fuel cell is controlled to switch from the open state to the closed state, and the target grid is closed, so that the temperature of the coolant may be better increased, so as to facilitate rapid start of the system. The target grid may be any of the grids 1, 2 and 3 in fig. 2.
It should be noted that in order to avoid accumulation of hydrogen leakage in the front compartment, the grille is kept open in the vehicle-inactive state, ventilation is ensured, and the occurrence probability of an increase in hydrogen concentration is reduced as much as possible.
And after the target grille is converted from the open state to the closed state, or in the process of converting the target grille from the open state to the closed state, acquiring the target refrigerant temperature of the target radiator corresponding to the target grille. As shown in fig. 2, when the target grille is grille 1, the corresponding target radiator is radiator 4; when the target grille is the grille 2, the corresponding target radiator is the radiator 6; when the target grille is grille 3, the corresponding target radiator is radiator 5.
After the target refrigerant temperature is obtained, judging whether the target refrigerant temperature is greater than a preset temperature threshold, and when the target refrigerant temperature is less than or equal to the preset temperature threshold, meaning that the temperature does not reach the starting temperature of the vehicle yet, continuing waiting is needed. When the target refrigerant temperature is greater than the preset temperature threshold, it means that the temperature has reached the starting temperature of the vehicle, and the starting may be continued, i.e., step S13 is performed.
With respect to step S13, when the target refrigerant temperature is greater than the preset temperature threshold, the target grille is controlled to be switched from the closed state to the open state, and the opening angle of the target grille is determined according to the target refrigerant temperature.
When the target refrigerant temperature is greater than the preset temperature threshold, the temperature is up to the starting temperature of the vehicle, and in order to avoid the overhigh temperature of the fuel cell stack, more air needs to be provided for the vehicle to reduce the refrigerant temperature, so that the target grille can be controlled to be switched from the closed state to the open state, and the fuel cell stack can be cooled conveniently. In the process of controlling the target grille to be converted from the closed state to the open state, the opening angle of the target grille can be determined according to the target refrigerant temperature, namely, the higher the target refrigerant temperature is, the larger the opening angle of the target grille is, the lower the target refrigerant temperature is, and the smaller the opening angle of the target grille is. The embodiment controls the opening of the target grille in a stepless control mode.
Specifically, the blades of the target grille are controlled to rotate at a preset rotational angular velocity, so that the target grille is switched from a closed state to an open state. The preset rotational angular velocity may be set according to the specific circumstances.
In the process of controlling the target grille to be converted from the closed state to the open state, the method further comprises:
Step S21, updating the target refrigerant temperature;
step S22, when the updated target refrigerant temperature is in a preset temperature range, controlling the blades of the target grille to keep the current angle; the pre-running temperature range is a temperature range which is more than or equal to a third target temperature and less than or equal to a fourth target temperature, and the third target temperature is less than the fourth target temperature;
Step S23, when the updated target refrigerant temperature is smaller than the third target temperature, controlling the blades of the target grille to reduce the opening angle until the target refrigerant temperature is within a preset temperature range;
and S24, when the target refrigerant temperature is greater than the fourth target temperature, controlling the blades of the target grille to increase the opening angle until the target refrigerant temperature is within the preset temperature range.
And continuously monitoring the temperature of the target refrigerant in the process of converting the closed state into the open state of the target grille, and judging the temperature of the target refrigerant.
When the target refrigerant temperature is in the pre-running temperature range, namely when the target refrigerant temperature is greater than or equal to the third target temperature and less than or equal to the fourth target temperature, the current refrigerant temperature is proper, the air inlet quantity of the target grille is not required to be adjusted, and then the blades of the target grille are controlled to keep the current angle, so that the air inlet area of the target grille is smaller as much as possible under the premise of ensuring the heat dissipation effect, and the wind resistance of the whole vehicle is reduced as much as possible. The pre-running temperature range can be the optimal working water temperature range of the fuel cell stack, and can be specifically set according to the working technical requirements of the stack.
When the target refrigerant temperature is not in the pre-running temperature range, namely when the target refrigerant temperature is smaller than the third target temperature, the refrigerant temperature is lower, and heat dissipation is too fast, so that the blades of the target grille are required to be controlled to reduce the opening angle, further the air inlet quantity is reduced, the temperature of the refrigerant is improved, the target refrigerant temperature can be in the pre-running temperature range, and all parts of the vehicle are at the optimal working temperature.
Or when the target refrigerant temperature is higher than the fourth target temperature, the refrigerant temperature is higher, and the heat dissipation is too slow, so that the blades of the target grille are required to be controlled to increase the opening angle, further the air inlet quantity is increased, the temperature of the refrigerant is reduced, the target refrigerant temperature can be in a pre-running temperature range, and all parts of the vehicle are at the optimal working temperature.
In summary, in this embodiment, when the vehicle is started, whether the front cabin hydrogen concentration is smaller than the first preset hydrogen concentration is detected first, so that it can be determined whether the vehicle is in a hydrogen leakage state, and the fuel cell vehicle can be prevented from being started in the hydrogen leakage state, thereby reducing the occurrence probability of safety accidents. Further, when the fuel cell vehicle does not leak hydrogen, the control target grille is switched from the open state to the closed state to more rapidly increase the refrigerant temperature, so that the vehicle can be started quickly. And the temperature of the target refrigerant is monitored, and the opening angle of the target grille is determined according to the temperature of the target refrigerant, so that the opening angle of the target grille can be reduced as much as possible while the heat dissipation of a galvanic pile is met, the wind resistance of the whole automobile is reduced as much as possible, and the economical efficiency of the fuel cell automobile is improved.
The technical scheme provided by the embodiment can be suitable for independent control of a plurality of grids on the vehicle. For example, the three grids shown in fig. 2 may be separately controlled in the above-described manner in a closed state, an open state, and an open angle, respectively. Among the 3 grids shown in fig. 2, the grid 1 is slightly different from the grids 2 and 3, the grid 1 corresponds to the fuel cell stack 8, mainly dissipates heat of the fuel cell stack 8, and a corresponding condenser 7 (a heat dissipation component belonging to an air conditioner) is arranged on the grid 1 so as to better dissipate heat of the fuel cell stack 8, while the grids 2 and 3 mainly dissipate heat of an accessory component of the fuel cell stack 8, and the condenser 7 is not involved. Therefore, when controlling the grid corresponding to the fuel cell stack, the parameters of the air conditioner need to be considered, and the specific control modes are as follows:
When the target grid is a first grid (grid 1 as shown in fig. 2) corresponding to a fuel cell stack of a fuel cell vehicle, the method further comprises:
step S31, acquiring the air conditioning loop pressure of the fuel cell automobile;
And S32, when the target refrigerant temperature is greater than a preset temperature threshold value or the air conditioning loop pressure is greater than a preset pressure threshold value, controlling the target grille to be switched from a closed state to an open state, and determining the opening angle of the target grille according to the target refrigerant temperature.
Step S31 and step S12 may be performed simultaneously, i.e., the target coolant temperature of the target radiator corresponding to the target grille is obtained, and the air conditioning circuit pressure of the fuel cell vehicle is obtained. And judging the target refrigerant temperature and the air conditioning circuit pressure.
When the temperature of the target refrigerant is less than or equal to a preset temperature threshold value and the pressure of the air conditioning loop is less than or equal to a preset pressure threshold value, the electric pile still does not need to dissipate heat in the current state, and needs to wait continuously, and the target grille needs to be controlled to keep a closed state.
When the temperature of the target refrigerant is greater than a preset temperature threshold value or the pressure of the air conditioning loop is greater than a preset pressure threshold value, the heat dissipation of the electric pile is required as long as at least one of the temperature and the pressure is met, and the target grille can be controlled to be switched from a closed state to an open state.
In the process of controlling the target grille to be converted from the closed state to the open state, the method further comprises:
step S41, updating the target refrigerant temperature and the air conditioning circuit pressure;
Step S42, when the updated target refrigerant temperature is in a preset temperature range or the updated air conditioning loop pressure is in a preset pressure range, controlling the blades of the target grille to keep the current angle; the preset temperature range is a temperature range which is more than or equal to a first target temperature and less than or equal to a second target temperature, and the first target temperature is less than the second target temperature; the preset pressure range is a pressure range which is greater than or equal to a first target pressure and less than or equal to a second target pressure, and the first target pressure is less than the second target pressure;
Step S43, when the updated target refrigerant temperature is smaller than the first target temperature or the updated air conditioning circuit pressure is smaller than the first target pressure, controlling the blades of the target grille to reduce the opening angle until the target refrigerant temperature is within a preset temperature range and the air conditioning circuit pressure is within a preset pressure range;
And S44, when the target refrigerant temperature is greater than the second target temperature or the air conditioning circuit pressure is greater than the second target pressure, controlling the blades of the target grille to increase the opening angle until the target refrigerant temperature is within a preset temperature range and the air conditioning circuit pressure is within a preset pressure range.
And continuously monitoring the target refrigerant temperature and the air conditioning circuit pressure in the process of converting the target grille from the closed state to the open state, and judging the target refrigerant temperature and the air conditioning circuit pressure.
When the target refrigerant temperature is in a preset temperature range or the air conditioning loop pressure is in a preset pressure range, namely when the target refrigerant temperature is greater than or equal to the first target temperature and less than or equal to the second target temperature or the air conditioning loop pressure is greater than or equal to the first target pressure and less than or equal to the second target pressure, the current refrigerant temperature is proper, or the air conditioning loop pressure is proper, the air inlet quantity of the target grille is not required to be adjusted, and the blades of the target grille are controlled to keep the current angle, so that the air inlet area of the target grille is smaller as much as possible under the premise of ensuring the heat dissipation effect, and the windage of the whole vehicle is reduced as much as possible. The preset temperature range may be an optimal operating water temperature range of the fuel cell stack, and may specifically be set according to an operating technical requirement of the stack.
When the target refrigerant temperature is not in the preset temperature range, namely when the target refrigerant temperature is smaller than the first target temperature or the air conditioning circuit pressure is smaller than the first target pressure, the refrigerant temperature is lower or the air conditioning pressure is lower, and the heat dissipation is too fast, so that the blades of the target grille are required to be controlled to reduce the opening angle, the air inlet quantity is reduced, the temperature of the refrigerant is improved, the target refrigerant temperature can be in the preset temperature range, or the air conditioning circuit pressure is in the preset pressure range, and all parts of the vehicle are at the optimal working temperature or the optimal air conditioning circuit pressure.
Or when the target refrigerant temperature is greater than the second target temperature or the air conditioning circuit pressure is greater than the second target pressure, the refrigerant temperature is higher or the air conditioning circuit pressure is too high, and the heat dissipation is too slow, so that the blades of the target grille are required to be controlled to increase the opening angle, further the air inlet quantity is increased, the temperature of the refrigerant is reduced or the air conditioning circuit pressure is reduced, the target refrigerant temperature can be in a preset temperature range, or the air conditioning circuit pressure is in a preset pressure range, and all parts of the vehicle are at the optimal working temperature or the optimal air conditioning circuit pressure.
In summary, in this embodiment, when the vehicle is started, whether the front cabin hydrogen concentration is smaller than the first preset hydrogen concentration is detected first, so that it can be determined whether the vehicle is in a hydrogen leakage state, and the fuel cell vehicle can be prevented from being started in the hydrogen leakage state, thereby reducing the occurrence probability of safety accidents. Further, when the fuel cell vehicle does not leak hydrogen, the control target grille is switched from the open state to the closed state to more rapidly increase the refrigerant temperature, so that the vehicle can be started quickly. And the temperature of the target refrigerant is monitored, and the opening angle of the target grille is determined according to the temperature of the target refrigerant, so that the opening angle of the target grille can be reduced as much as possible while the heat dissipation of a galvanic pile is met, the wind resistance of the whole automobile is reduced as much as possible, and the economical efficiency of the fuel cell automobile is improved.
In the process of executing the above scheme, if the key-off signal of the whole car of the fuel cell car is detected, this means that the whole car needs to stop running, and at this time, it needs to be determined whether the whole car has hydrogen leakage again, so that the hydrogen concentration of the second front cabin of the fuel cell car needs to be obtained, or the hydrogen concentration of the first front cabin of the fuel cell car needs to be updated.
When the hydrogen concentration of the second front cabin is smaller than the second preset hydrogen concentration, the fact that the whole vehicle does not leak hydrogen is meant, the target grille can be controlled to be opened and kept in an open state, the front cabin in the grille is kept ventilated in a parking state of the whole vehicle, hydrogen accumulation is avoided, and then the occurrence probability of safety accidents is reduced.
When the hydrogen concentration of the second front cabin is greater than or equal to the second preset hydrogen concentration, the fact that the whole vehicle is likely to leak hydrogen is indicated, and the fuel cell automobile needs to be controlled to send out alarm information so as to remind passengers or drivers to timely treat the hydrogen leakage or timely evacuate people away from the passengers or drivers, and casualties are avoided.
In summary, the embodiment detects whether the whole vehicle has hydrogen leakage again when the fuel cell automobile is parked, so that the safety of the whole vehicle is further improved, and the occurrence probability of safety accidents is reduced.
Taking the heat dissipation system shown in fig. 2 as an example, a specific example will be provided with reference to fig. 3 to further explain the foregoing scheme provided in this embodiment.
When the whole car generates a KEY start signal (KEY ON), checking the hydrogen leakage condition of the front cabin, and if the hydrogen leakage is detected, sending hydrogen leakage information to an instrument display by the controller so as to remind a driver or a passenger of hydrogen leakage; if the leakage is detected, the whole vehicle continues to execute the starting program, and the controller sends instructions to control the grids 1,2 and 3 to be closed.
The controller monitors the water temperature T4 of the radiator 4, the water temperature T5 of the radiator 5, the water temperature T6 of the radiator 6, and the air conditioning circuit pressure P.
For grille 1, when P is less than preset pressure threshold P limit and T4 is less than preset temperature threshold T4 limit, the controller does not control grille 1 to open; when the air conditioner pressure P is larger than P limit, the air conditioner is operated, and grille inlet is required to be opened, or when the radiator loop water temperature T4 is larger than T4 limit, the radiator 4 cooling loop water temperature is increased, grille inlet cooling is required to be opened for further operation, and the controller controls the grille 1 to be opened gradually.
For the grille 2, when the T6 is smaller than the preset temperature threshold T6 limit, the controller does not control the grille 2 to be opened; when the water temperature T6 of the radiator loop is more than T6 limit, the water temperature of the cooling loop of the radiator 6 is increased, the grille air inlet cooling is required to be started for further work, and the controller controls the grille 2 to be opened gradually.
For the grid 3, when the T5 is smaller than the preset temperature threshold T5 limit, the controller does not control the grid 3 to be opened; when the water temperature T6 of the radiator loop is more than T6 limit, the water temperature of the cooling loop of the radiator 6 is increased, and the grille air inlet cooling is required to be started for further work; the controller controls the grille 3 to be opened gradually at this time.
When the controller receives a vehicle shutdown command KEY OFF, the concentration of hydrogen is detected again, whether the hydrogen leaks or not is determined, if no leakage exists, the controller controls each grille to be reset to an open state, and if leakage exists, alarm information is sent.
In the whole vehicle running process, in order to ensure better economy and reduce the whole vehicle resistance, each grille can reduce the opening of the grille blades as much as possible under the condition of meeting the basic cooling air inlet requirement of the corresponding cooling circuit, as shown in fig. 4. The controller monitors the water temperature T4, the water temperature T5, the water temperature T6 and the air conditioning circuit pressure P.
For the grille 1, when P is within the preset pressure range Pe (indicated by the form p=pe in fig. 4), or T4 is within the preset temperature range Te (indicated by the form t4=te in fig. 4), it indicates that the air-conditioning operation pressure or the stack cooling circuit water temperature is in the optimum operation state, and the controller controls the grille 1 to maintain the current opening angle state. When the air conditioner pressure P is greater than the maximum pressure in the Pe range (represented by P > Pe in FIG. 4), or T4 is greater than the maximum temperature in Te (represented by T4 > Te in FIG. 4), the cooling air inlet of the grille 1 is insufficient, the blades of the grille 1 are required to be further opened, and the controller controls the grille 1 to enlarge the opening angle of the grille 1 until P is in Pe; when the air-conditioning pressure P is less than the minimum pressure in the Pe range or T4 is less than the minimum temperature in Te, indicating that the grille 1 is cooled too much, the controller controls the grille 1 to decrease the opening angle of the grille 1 until P is in Pe or t4=te.
Aiming at the grid 3, when the temperature T5 is in a preset temperature range T5r, indicating that the water temperature of the cooling circuit is in an optimal working state, and controlling the grid 3 to keep a current opening angle state by a controller; when T5 is greater than the maximum temperature in T5r, the grille 3 is indicated to be insufficient in cooling air inlet, the blades of the grille 3 are required to be further opened, and the controller controls the grille 3 to enlarge the opening angle of the grille 3 until T5 is within T5 r. When T5 is less than the minimum temperature in T5r, the grille 3 is indicated to be cooled too much, and the controller controls the grille 3 to reduce the opening angle of the grille 3 until T5 is within T5 r.
Aiming at the grille 2, when the temperature T6 is in a preset temperature range T6r, the water temperature of the cooling circuit is indicated to be in an optimal working state, and the controller controls the grille 2 to keep a current opening angle state; when the temperature T6 is greater than the maximum temperature in the temperature T6r, the condition that the cooling air inlet of the grille 2 is insufficient is indicated, the blades of the grille 2 are required to be further opened, and at the moment, the controller controls the grille 2 to enlarge the opening angle of the grille 2 until the temperature T6 is within the temperature T6 r; when T6 is less than the minimum temperature in T6r, the grille 2 is indicated to be cooled and air is excessively supplied, and the controller controls the grille 2 to reduce the opening angle of the grille 2 until T6 is within T6 r.
Wherein, the grids 1, 2 and 3 can be controlled independently.
In summary, the opening angle of the active grille is controlled according to the temperature or the pressure, so that the resistance of the fuel cell automobile in the driving process due to the large opening area of the grille due to the heat dissipation requirement is reduced; each grid controls the angle adjustment of the grids according to the cooling temperature requirement of the corresponding cooling loop, and the control precision is higher; when the whole vehicle is started and shut down, a hydrogen leakage checking program is added, the grille is set to be in an initial reset state, and the hydrogen safety of the fuel cell is ensured.
