Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
Interpretation of related terms:
a fuel cell: an electrochemical energy conversion device is capable of directly converting chemical energy in reactants (fuel and oxidant) into electrical energy. The fuel cell in the embodiment of the invention mainly refers to a hydrogen fuel cell.
The VCU is mainly used for coordination and control of a vehicle power system.
The vehicle-mounted terminal: the vehicle positioning information, the CAN bus information and the fault information CAN be sent to a data server of a remote monitoring center through a GPRS/WIFI network and the like. Referring to fig. 1, a communication method between a conventional vehicle-mounted terminal and a vehicle control unit is shown. The vehicle-mounted terminal mainly comprises: the device comprises a power supply processing and converting module, a satellite positioning module, a communication and interface module and a data storage module. The communication and interface module supports GPRS/WIFI communication and CAN bus communication. The VCU uploads the information of the whole vehicle and key parts to the vehicle-mounted terminal through the CAN bus, and the vehicle-mounted terminal uploads the positioned position information and the whole vehicle parameters acquired from the VCU to the server through the GPRS/WIFI. At present, the communication transmission between the VCU and the vehicle-mounted terminal is unidirectional, and the vehicle-mounted terminal can only acquire information uploaded by the VCU and cannot transmit the information to the VCU.
State of charge: the SOC, which is used to reflect the remaining capacity of the battery, is numerically defined as the ratio of the remaining capacity to the battery capacity.
The hydrogen is extremely easy to burn, and when the volume of the hydrogen accounts for 4.1 to 75 percent of the total volume of the mixed gas, the explosion limit of the hydrogen is reached. See the fuel cell hydrogen supply subsystem shown in fig. 2. In order to ensure the purity of hydrogen in the fuel cell circulation loop, the hydrogen in the hydrogen circulation loop needs to be discharged out of the vehicle according to a certain strategy in the running process of the whole vehicle, and part of the hydrogen comes from unreacted hydrogen in the fuel cell stack. At present, the hydrogen discharge switch valve is mainly opened at fixed time to discharge hydrogen out of the vehicle.
The application scene of the control strategy of the existing fuel cell vehicle is mainly outdoors, and no special control requirement is made for vehicles needing to enter and exit indoors. The control strategy of the existing fuel cell vehicle is as follows:
when the whole vehicle is started or operated, whether the fuel cell needs to be started or not can be judged according to the SOC of the power battery, the required power of the whole vehicle, the vehicle speed, the self state of the fuel cell and the like. The current strategy requires that the fuel cell is not recommended to be shut down once the fuel cell is started, unless the fuel cell reports a fault or the power cell SOC is higher than a set threshold value X (the threshold value is generally set higher, and if the threshold value is set lower, frequent start and stop of the fuel cell may be caused). The number of times that the fuel cell is allowed to start and stop is generally 1 hour and several times, and the more frequent start-up/shut-down can cause the early decline of the performance of the fuel cell stack.
Therefore, for the fuel cell vehicle of the current control strategy to enter the room, except that the SOC of the power battery is just higher than the set threshold value X and the pure electric operation mode is entered in the room during the period of entering the room, otherwise the fuel cell can operate, hydrogen can be discharged into the room at regular time, and the potential safety hazard is increased.
For fuel cell vehicles entering or exiting a room (the room comprises the following scenes of relatively closed and non-open places such as factory buildings, workshops and the like), if the fuel cells are started when the vehicles run indoors, the whole vehicle can discharge hydrogen regularly. And the indoor space is a relatively closed space, a plurality of fuel cell vehicles run, and hydrogen is accumulated, so that the risk of explosion is caused.
In order to solve the above problem, an embodiment of the present invention provides a control system for a fuel cell vehicle, which is schematically shown in fig. 3, and includes:
the vehicle-mounted terminal 20 is provided with an output module 201 for transmitting information to the vehicle control unit 10, and the output module 201 is in communication connection with the vehicle control unit 10 through a CAN bus.
And the vehicle-mounted terminal 20 is used for positioning the position information of the vehicle and transmitting the position information of the vehicle to the vehicle control unit 10 through the output module 201.
And the vehicle control unit 10 is used for turning off a fuel cell of the vehicle and controlling the vehicle to enter the pure electric driving mode under the condition that the vehicle is determined to enter the indoor space based on the position information of the vehicle.
The embodiment of the invention adds an output module 201 on the basis of the existing vehicle-mounted terminal 20. As long as the whole vehicle is connected with low voltage electricity, the vehicle-mounted terminal 20 positions the vehicle in real time, and transmits the position information obtained by positioning to the whole vehicle controller 10 through the output module 201 and the CAN bus.
Further, the vehicle control unit 10 stores position information of a building in advance, and performs MAP query based on the position information of the vehicle to determine whether a position point where the vehicle is located indoors in the building.
It should be noted that, in the process that the vehicle enters the pure electric driving mode and travels to the indoor destination, the vehicle controller 10 controls the maximum speed of the vehicle not to exceed the vehicle speed limit, and the vehicle speed limit may be calibrated according to the discharge power capability of the power battery. Fig. 4 shows an example of an electric-only driving mode.
In practical applications, the vehicle control unit 10 for determining that a vehicle enters a room based on the position information of the vehicle is specifically configured to:
calculating the relative distance between the vehicle and the building according to the position information of the vehicle and the position information of the building where the vehicle needs to enter the room; judging whether the relative distance is greater than a preset first distance threshold value representing the indoor range; if the relative distance is not greater than the first distance threshold, it is determined that the vehicle enters the room of the building.
See figure 5 for a schematic view of a building. A is the central position of the building, L1To characterize the first distance threshold into the indoor range, the relative distance L of the vehicle from the building center point is calculated from the position information of the vehicle and the position information of the building into which the vehicle needs to enter.
If L is less than or equal to L1It means that the vehicle enters the room of the building, at which time the fuel cell of the vehicle may be turned off and the vehicle may be controlled to enter the electric-only driving mode. If L is>L1This indicates that the vehicle is located outside of the building, at which time the vehicle may be operated normally in accordance with existing control strategies.
It should be noted that at least one building that needs to enter the room may be preset for the vehicle, and each building located near the location point of the vehicle may also be queried through the MAP as the building that needs to enter the room.
Further, to ensure normal operation in the pure electric driving mode, the controller in the embodiment of the present invention is further configured to:
judging whether the actual state of charge of the vehicle meets a preset required state of charge or not; and if the actual state of charge meets the required state of charge, executing control to enable the vehicle to enter a pure electric driving mode.
In the embodiment of the invention, the required state of charge can be determined at least by the mass of the whole vehicle (fixed value, according to the maximum mass at ordinary times) and the vehicle speed (fixed value, according to the maximum vehicle speed allowed indoors). Of course, in order to improve the accuracy of the required state of charge, the first distance threshold representing the indoor entering range and/or the second distance threshold representing the indoor allowed parking charging range may be determined by combining, which is not limited in the embodiment of the present invention.
Furthermore, in order to ensure the normal operation of the power battery, the controller in the embodiment of the present invention is further configured to:
if the actual state of charge does not meet the required state of charge, judging whether the relative distance is greater than a preset second distance threshold value representing the range of charging allowing the vehicle to stop indoors, wherein the second distance threshold value is smaller than the first distance threshold value; if the relative distance is larger than the second distance threshold, a charging prompt is carried out to prompt a user to stop and charge; and under the condition that the vehicle is not powered off, stopping the vehicle, controlling the vehicle to enter a mode of charging the power battery by the fuel battery, and executing control to enable the vehicle to enter a pure electric driving mode until the new actual state of charge of the vehicle meets the required state of charge.
See figure 6 for a schematic view of a building. A is the central position of the building, L1To characterize the first distance threshold into the indoor range, L2Second distance for characterizing charging range for allowing parking in roomAnd calculating the relative distance L between the vehicle and the center point of the building according to the position information of the vehicle and the position information of the building in which the vehicle needs to enter.
If L is2＜L≤L1It indicates that the vehicle enters the indoor allowable parking charging range, and at this time, a charging prompt may be generated through the meter to prompt the vehicle controller 10 to park to charge the power battery. The vehicle control unit 10 controls the vehicle to stop and controls the fuel cell to charge the power battery when the vehicle is not powered off. And when the new actual state of charge of the fuel cell meets the required state of charge, closing the fuel cell, enabling the vehicle to enter a pure electric driving mode to drive to an indoor destination, and simultaneously controlling the maximum speed of the vehicle not to exceed the vehicle speed limit value. Fig. 7 gives an example of a mode in which the fuel cell charges the power cell.
Still further, in order to solve the problem that the vehicle cannot leave the room in the pure electric driving mode due to the failure of the power battery or other abnormal reasons, the controller in the embodiment of the present invention is further configured to:
and if the relative distance is not greater than the second distance threshold, performing fault prompt to prompt a user to manually start the fuel cell so as to enable the vehicle to enter a fuel cell running mode.
In the embodiment of the invention, if the residual capacity of the power battery is insufficient when the vehicle is in the charging range which does not allow parking, the power electric fault or the fault caused by other abnormal reasons is likely to occur, and the alarm prompt of the whole vehicle can be realized by a driver to manually start the fuel battery running mode so as to ensure that the whole vehicle can run. Fig. 8 gives an example of a fuel cell running mode.
The control system of the fuel cell vehicle provided by the embodiment of the invention can reduce and even completely eliminate potential safety hazards caused by the timing discharge of hydrogen when the fuel cell is started when the vehicle runs indoors, and improves the running safety.

And S20, under the condition that the vehicle is determined to enter the room based on the position information of the vehicle, the fuel cell of the vehicle is closed, and the vehicle is controlled to enter the pure electric running mode.
