Referring to fig. 1, an oil tank filling control method provided by a first embodiment of the present application is shown, where the oil tank filling control method provided by the present embodiment can ensure that steam in a high-pressure oil tank is in a safe range, correspondingly eliminates potential safety hazards, and improves user experience.
Specifically, the method for controlling the refueling of the fuel tank provided in this embodiment is characterized in that the method includes:
step S10, when a user starts a refueling switch, controlling the suction of a CG relay, and sending a refueling request signal to an engine controller so that the engine controller opens a fuel tank pressure release valve and releases pressure of a fuel tank;
specifically, in the embodiment, it should be firstly explained that the oil tank oiling control method provided in the embodiment is specifically applied to an oil-electric hybrid electric vehicle and is used for optimizing an oiling control strategy of the hybrid electric vehicle so as to eliminate potential safety hazards possibly occurring in the oiling process and correspondingly improve the use experience of a user. In addition, it should be noted that, the fuel tank refueling control method provided in this embodiment is implemented based on hardware such as a vehicle controller, a vehicle body controller, an engine controller, a CG relay, a refueling switch and the like, which are disposed in a vehicle body, and control of mailbox refueling is correspondingly completed through signal interaction between the hardware.
In this step, it should be noted that, when the vehicle controller detects that the user has activated the refueling switch, that is, the name of the current user needs to refuel the current vehicle, based on this, the vehicle controller will immediately control the CG relay to be closed so as to switch on the power supply, further, and immediately send a refueling request signal to the engine controller, on this basis, the engine controller will immediately correspondingly open the tank relief valve, so that the interior of the current tank can be effectively relieved.
Step S20, acquiring an oil tank pressure value inside the oil tank and an atmospheric pressure value outside the oil tank in real time, and calculating a pressure difference value between the atmospheric pressure value and the oil tank pressure value;
further, in this step, it should be noted that, in order to enable the pressure inside the fuel tank to be within a reasonable range, this step may collect, in real time, the fuel tank pressure value inside the fuel tank at present and the atmospheric pressure value outside the fuel tank at present, and specifically, both have specific numerical values.
Based on this, it is also necessary to calculate the pressure difference between the current atmospheric pressure value and the current tank pressure value in further real time for the subsequent processing.
Step S30, judging whether the pressure difference value is larger than a preset threshold value in a preset time period or not in real time through a vehicle body controller;
further, in this step, it should be noted that, after the required pressure difference is calculated through the above steps, the body controller in the current vehicle is correspondingly activated at this time to perform the secondary processing.
Specifically, the step corresponds to determining the change condition of the current pressure difference in real time through the current vehicle body controller, wherein it is to be noted that, because the pressure value of the oil tank and the atmospheric pressure value are both dynamically changed, the pressure difference between the two is also dynamically changed. On the basis, the current vehicle body controller can judge whether the current pressure difference value is larger than a preset threshold value in a preset time period in real time.
And S40, if the pressure difference value is judged to be smaller than or equal to the preset threshold value in the preset time period in real time through the vehicle body controller, receiving a pressure release completion signal sent by the vehicle body controller, and unlocking a fuel tank cover of the fuel tank according to the pressure release completion signal.
Finally, in this step, it should be noted that, if it is determined in real time that the pressure difference is less than or equal to the preset threshold value in the preset time period in this step, it can be determined that the pressure release of the current oil tank is completed, and correspondingly, the whole vehicle controller also receives the pressure release completion signal sent by the vehicle body control in real time.
Further, the current whole vehicle controller can unlock the fuel tank cover of the fuel tank in the current vehicle according to the pressure release completion signal, so that subsequent refueling can be performed. Preferably, the preset time period is 10 seconds, and the preset threshold is 2Kpa, so that the fuel tank cover of the fuel tank in the interior of the current vehicle can be accurately controlled.
During the use, through the state of real-time detection oiling switch to correspond the control oil tank relief valve and carry out the pressure release to the oil tank when oiling switch starts, simultaneously, the inside oil tank pressure value of current oil tank and the outside atmospheric pressure value of current oil tank are gathered in real time, and correspondingly calculate the difference between the two, based on this, rethread automobile body controller judges whether pressure difference is greater than the threshold value in the time quantum of predetermineeing in real time, specifically, if not, then the normal pressure release completion signal that the automobile body controller sent, and the unblock is carried out to the fuel tank cap of oil tank in step, thereby can guarantee before refueling that the inside pressure of oil tank is in a reasonable scope, and then can ensure that steam in the high-pressure oil tank is in safe scope, corresponding elimination potential safety hazard has promoted user's use experience simultaneously.
It should be noted that the foregoing implementation procedure is only for illustrating the feasibility of the present application, but this does not represent that the fuel tank filling control method of the present application is only one implementation procedure, and may be incorporated into the feasible implementation of the fuel tank filling control method of the present application, as long as it can be implemented.
In summary, the oil tank refueling control method provided by the embodiment of the application can ensure that the steam in the high-pressure oil tank is in a safe range, correspondingly eliminates potential safety hazards, and improves the use experience of users.
The second embodiment of the present application also provides a fuel tank refueling control method, which is different from the fuel tank refueling control method provided in the first embodiment in that:
specifically, in this embodiment, the step of controlling the CG relay to be engaged and sending a fueling request signal to the engine controller includes:
when the fact that the user starts the oiling switch is detected, judging whether the current vehicle is in a low-high-voltage state or not;
if the current vehicle is in a low-high voltage state, receiving a hard wire high-level signal sent by the oiling switch, and sending a hard wire low-level signal to the CG relay based on the hard wire high-level signal so as to control the CG relay to be attracted through the hard wire low-level signal;
and if the vehicle is not in the low-high pressure state currently, generating a fuel-forbidden signal, and sending prompt information to an instrument panel of the vehicle currently based on the fuel-forbidden signal, wherein the prompt information comprises a text prompt and an icon prompt.
Specifically, in this embodiment, it should be noted that, when the whole vehicle controller detects that the user activates the fuel switch in real time, it indicates that the current user has a fuel demand on the vehicle, based on this, the current whole vehicle controller immediately determines whether the current vehicle is in a low-high-voltage state, that is, determines whether the current vehicle has flameout in real time. Specifically, if the current vehicle is judged in real time and is in a low-high voltage state, the hard-wire high-level signal sent by the oiling switch in real time is correspondingly received, and meanwhile, the hard-wire low-level signal is sent to the CG relay based on the hard-wire high-level signal, so that the CG relay can be changed from an off state to an on state, namely, the current CG relay is switched on, and the CG relay is connected with a power supply. Based on this, the CG relay wakes up the hardware such as the vehicle body controller, the engine controller, and the gateway.
Correspondingly, if the step judges in real time that the current vehicle is not in a low-high-pressure state, namely, the name of the current vehicle is not in a flameout state, the current whole vehicle controller generates a corresponding fuel-filling prohibition signal, and meanwhile, a prompt signal is sent to an instrument panel of the current vehicle, and specifically, the prompt information can be flameout and fuel-filling prohibition, so that a current user can be effectively reminded of flameout the current vehicle.
Specifically, in this embodiment, it should be further noted that, after the step of unlocking the fuel tank cover of the fuel tank according to the pressure release completion signal, the method further includes:
when the starting of the oiling to the oil tank is detected, controlling the vehicle body controller to start timing, and detecting the current vehicle speed of the vehicle and the timing time of the vehicle body controller in real time;
if the real-time detection shows that the current speed of the vehicle is greater than the preset speed or the timing time of the vehicle body controller exceeds the preset time, judging that the current vehicle refueling is completed, and locking the fuel tank cover of the fuel tank.
Specifically, in this embodiment, it should also be noted that, after the fuel tank cover of the fuel tank in the current vehicle is unlocked in the above manner, the current fuel tank may be refueled at this time, and specifically, when the whole vehicle controller detects in real time that the fuel tank in the current fuel tank has been filled with fuel, the vehicle body controller is correspondingly controlled to start timing, so that the current vehicle body controller collects the refueled time of the current vehicle in real time, that is, the timing time. Meanwhile, the speed of the current vehicle is synchronously detected to judge whether the current vehicle is started or not.
Specifically, if it is detected in real time that the speed of the current vehicle is greater than the preset speed or the timing time of the vehicle body controller exceeds the preset time, the fact that the current vehicle is filled with fuel can be accurately judged, so that the fuel tank cover of the current fuel tank can be correspondingly locked, preferably, the preset speed can be 5km/h, the preset time can be 15 minutes, and the fuel tank can be accurately controlled.
In addition, in this embodiment, it should be noted that, the method further includes:
if the pressure difference value is judged to be larger than the preset threshold value in the preset time period in real time through the vehicle body controller, judging that the oil tank has pressure relief faults, and generating corresponding fault signals;
and sending the fault signal to the vehicle body controller so that the vehicle body controller closes a fuel tank cover of the fuel tank, and synchronously sending the fault signal to the engine controller so that the engine controller closes the fuel tank pressure release valve to stop pressure release to the fuel tank.
In addition, in this embodiment, it should be noted that, if the vehicle body controller in this embodiment determines that the pressure difference is greater than the preset threshold in the preset time period, it may correspondingly determine that the pressure relief fault occurs in the current fuel tank, and immediately generate a corresponding fault signal. Specifically, when it is determined that the pressure difference exceeds 2Kpa within 10 seconds, the fault signal is immediately generated.
Further, the current fault signal is immediately sent to the vehicle body controller, so that the current vehicle body controller correspondingly closes the fuel tank cover of the fuel tank, and simultaneously the fault signal is synchronously sent to the engine controller, so that the current engine controller can further close the fuel tank pressure release valve in the current fuel tank, and pressure release of the current fuel tank is stopped.
In addition, in this embodiment, it should be further noted that the method further includes:
when the oil tank is detected to be filled, a corresponding oil filling completion signal is generated, and the oil filling completion signal is sent to the vehicle body controller, so that the vehicle body controller closes an oil tank cover of the oil tank;
and controlling the CG relay to be disconnected through a hard wire high level based on the oiling completion signal, so that the CG relay disconnects the power supply of the engine controller through a hard wire low level.
In addition, in this embodiment, it should be further noted that when the whole vehicle controller detects that the fuel tank is completely refueled in real time, a corresponding refueled complete signal is immediately generated, and at the same time, the refueled complete signal is sent to the vehicle body controller, so that the current vehicle body controller can correspondingly close the fuel tank cover of the current fuel tank, that is, perform locking processing on the fuel tank cover of the current fuel tank.
Furthermore, the CG relay is controlled to be disconnected through a hard wire high level on the basis of the refueling completion signal, so that the current CG relay can be disconnected with the power supply of the engine controller through a hard wire low level, and the refueling processing of the current fuel tank is finally completed.
In this embodiment, it should be noted that, the method further includes:
when the fault signal is generated, the audio equipment in the vehicle is synchronously started, and corresponding warning information is sent out through the audio equipment, and the warning information is played in a voice mode.
