In a first aspect, referring to fig. 1, the present invention provides a fuel cell management method comprising:
s100, determining the running environment state of the automobile;
s200, acquiring driving parameters of the automobile;
s300, controlling the vehicle controller to output a control signal according to the environment state and the driving parameters;
and S400, changing the working state of the fuel cell and the working state of the hydrogen cylinder valve according to the control signal.
During the driving process of the automobile, firstly, the environment state of the driving of the automobile is determined, and then the driving parameters of the automobile are obtained. According to the obtained environmental state and the driving parameters of the automobile, the current driving state of the automobile can be judged and obtained, and according to different driving states of the automobile, whether the operation of the fuel cell in different driving states causes potential safety hazards due to hydrogen accumulation generated during the operation of the fuel cell is judged, so that the whole automobile controller is controlled to output a control signal. The working state of the fuel cell and the working state of the hydrogen cylinder valve are controlled by the control signal. The method can effectively change the working state of the fuel cell and the working state of the hydrogen cylinder valve, so that the fuel cell stops working under dangerous conditions, the accumulation of hydrogen can be reduced, and the probability of accidents in the driving process of the automobile is reduced.
Referring to fig. 2, in some embodiments, step S100 includes:
s110, if the first inspection distance of the automobile at the current moment is smaller than the first inspection distance at the last moment, determining that the environment state is a first state;
s120, if the second inspection distance of the automobile at the current moment is greater than the second inspection distance at the previous moment, determining that the environmental state is a second state;
s130, if the current safe driving distance of the automobile is smaller than or equal to the safe driving distance threshold value, determining that the environmental state is a third state;
s140, if the fire condition in the vehicle is determined according to the acquired smoke information and the primitive image, determining that the environmental state is a fourth state;
and S150, if the situation of fire outside the vehicle is determined according to the acquired smoke information and the primitive images, determining that the environment state is a fifth state.
When the running environment state of the automobile is confirmed and determined, the distance between the current moment of the automobile and obstacles on front and rear vehicles and front and rear road conditions can be monitored in real time through radars arranged in front and rear of the automobile, and smoke information and fire information inside and outside the automobile can be acquired through smoke sensors and image acquisition units arranged inside and outside the automobile. Specifically, when the distance to the front obstacle (i.e., the first inspection distance at the current moment) detected by the front radar of the automobile is smaller than the distance to the front obstacle (i.e., the first inspection distance at the previous moment) detected by the front radar of the automobile stored at the previous moment, it is determined that the automobile is in the first state of entering the closed environment. And if the distance between the rear radar of the automobile and the rear obstacle (namely the second inspection distance at the current moment) is larger than the distance between the rear radar of the automobile and the rear obstacle (namely the second inspection distance at the previous moment) stored at the previous moment, determining that the automobile is in a second state far away from the closed environment. When any one of the front and rear radars of the automobile detects that the distance between the front and rear vehicles and the automobile (i.e. the current safe driving distance) is less than the safe driving distance threshold value, it is determined that the automobile is in a third state of imminent collision. When the smoke sensor and the image acquisition unit in the automobile detect smoke or fire, the automobile is determined to be in a fourth state of the fire in the automobile. And if the smoke sensor and the image acquisition unit outside the automobile detect smoke or fire, determining that the automobile is in a fifth state close to a fire source. According to the mode, the distance information acquired by the front radar and the rear radar of the automobile, the smoke information acquired by the smoke sensor and the fire information acquired by the image acquisition unit are combined, so that the driving state of the automobile can be conveniently judged, whether the operation of the fuel cell in different driving states causes potential safety hazards due to hydrogen accumulation generated during the operation of the fuel cell can be judged according to different driving states of the automobile, and the whole automobile controller is controlled to output a control signal. The working state of the fuel cell and the working state of the hydrogen cylinder valve are controlled by the control signal. By changing the working state of the fuel cell and the working state of the hydrogen cylinder valve, the fuel cell stops working under dangerous conditions, the hydrogen accumulation can be reduced, and the accident probability in the driving process of the automobile is reduced. It should be noted that the size of the safe driving distance threshold may be set in real time according to the current vehicle speed information, without limitation.
Referring to fig. 3, in some embodiments, step S300 includes:
s311, if the environment state is a first state and the initial working state of the fuel cell is a closed state, determining that the cruising distance of the automobile is greater than a first safe distance according to the charge state of the power cell and the current energy consumption information, and controlling the whole automobile controller not to output a signal;
s312, if the environment state is a first state and the initial working state of the fuel cell is an opening state, determining that the cruising distance of the automobile is smaller than a first safe distance according to the charge state of the power cell and the current energy consumption information, and controlling the whole automobile controller not to output a signal;
s313, if the environment state is a first state and the initial working state of the fuel cell is a closed state, determining that the cruising distance of the automobile is less than a first safe distance according to the charge state of the power cell and the current energy consumption information, and controlling the whole automobile controller to output a starting signal;
and S314, if the environment state is the first state and the initial working state of the fuel cell is the starting state, determining that the cruising distance of the automobile is greater than the first safe distance according to the charge state of the power cell and the current energy consumption information, and controlling the whole automobile controller to output a closing signal.
And judging whether the automobile is in a first state or not when the vehicle control unit is controlled to output a control signal according to the environment state and the driving parameters. When the automobile is in a first state, predicting the running state of the automobile within a certain time according to the acquired initial working state of the fuel cell, the charge state of the power cell and the current energy consumption information, specifically: when the fuel cell is in a closed state, when the cruising distance of the automobile is larger than a preset first safety distance according to the charge state of the current power cell and the energy consumption information of the current automobile, the fact that the automobile can safely leave the first state is judged, and the whole automobile controller is controlled not to output signals. When the fuel cell is in an open state, and the cruising distance of the automobile obtained according to the charge state of the current power cell and the energy consumption information of the current automobile is smaller than a preset first safety distance, the fact that the automobile cannot safely leave the first state is judged, and the vehicle controller is controlled not to output signals to enable the fuel cell to continuously work, output high-voltage electric signals and provide power for the automobile to leave the first environment. When the fuel cell is in a closed state, and when the cruising distance of the automobile obtained according to the charge state of the current power cell and the energy consumption information of the current automobile is smaller than a preset first safety distance, the fact that the automobile cannot safely leave the first environment is judged, the vehicle controller is controlled to output an opening signal to control the fuel cell to start working, a hydrogen cylinder valve is opened, and the fuel cell outputs high voltage to provide power for the automobile to leave the first environment. When the fuel cell is in an open state, and the cruising distance of the automobile is larger than a preset first safety distance according to the current charge state of the power cell and the current energy consumption information of the automobile, the automobile is judged to be capable of safely leaving the first environment, and in order to reduce the accumulation of hydrogen in the first environment, the whole automobile controller is controlled to output a closing signal to stop the work of the fuel cell and close the hydrogen cylinder valve. By the method, power can be provided for the automobile when the automobile cannot safely drive away from the first environment when the automobile enters the first state in the closed space, and the working state of the fuel cell and the working state of the hydrogen cylinder valve can be changed when the automobile can safely drive away from the first environment, so that the fuel cell stops working under dangerous conditions, and the hydrogen accumulation is reduced to reduce the probability of accidents in the driving process of the automobile.
It will be appreciated that the setting of the first safe distance is closely related to whether the vehicle can leave the first environment. In some cases, the first safety distance may be set to 20 km, but is not limited thereto.
Referring to fig. 4, in some embodiments, step S300 further includes:
s321, if the environment state is the second state and the initial working state of the fuel cell is the closing state, controlling the vehicle controller to output a starting signal;
and S322, if the environment state is the second state and the initial working state of the fuel cell is the starting state, controlling the whole vehicle controller not to output the control signal.
When the vehicle controller is controlled to output a control signal according to the environment state and the driving parameters, whether the vehicle is in the second state or not is judged, and when the vehicle is in the second state, the driving state of the vehicle far away from the dangerous road section is determined without considering potential safety hazards caused by hydrogen accumulation. When the working state of the fuel cell is the closing state, the vehicle controller is controlled to output an opening signal to control the fuel cell to start working and open the hydrogen cylinder valve, so that high voltage electricity is provided for the vehicle. And when the working state of the fuel cell is the starting state, controlling the vehicle controller not to output a control signal, so that the fuel cell continuously works and high voltage is continuously provided for the vehicle. According to the method, the automobile can be controlled to obtain more driving power in the second state far away from the closed space, so that the automobile can leave the dangerous road section more quickly, the staying time of the automobile on the dangerous road section is reduced, and the driving safety of the automobile is improved.
Referring to fig. 5, in some embodiments, step S300 further includes:
s331, if the environment state is the third state and the initial working state of the fuel cell is the closing state, controlling the whole vehicle controller not to output a control signal;
and S332, controlling the vehicle control unit to output a closing signal if the environment state is the third state and the initial working state of the fuel cell is the opening state.
And judging whether the automobile is in a third state or not when the vehicle control unit is controlled to output a control signal according to the environment state and the driving parameters. And if the automobile is in the third state, determining that the automobile is in a driving state about to collide. When the working state of the fuel cell is in a closed state, the vehicle controller is controlled not to output a control signal in order to prevent hydrogen explosion caused by vehicle collision. When the working state of the fuel cell is in an opening state, in order to prevent hydrogen explosion caused by automobile collision, the vehicle controller is controlled to output a closing signal to control the fuel cell to stop working, and meanwhile, the hydrogen cylinder valve is closed to reduce hydrogen accumulation and reduce the probability of explosion.
