[0002] Automobiles, especially commercial vehicles, primarily use diesel engines. Diesel fuel can wax at low temperatures, severely impacting vehicle performance. To adapt to cold environments, vehicles employ fuel preheating systems and dual fuel tanks to accelerate starting. However, these methods don't address the root cause of engine starting problems in low temperatures. Consequently, some vehicles resort to using high-octane, expensive fuel to overcome starting difficulties, even for a period after starting. This significantly increases operating costs.

[0025] In one implementation of this application, obtaining the vehicle's heat preservation impact parameters and determining the continuous heat preservation time of the fuel heat preservation control system based on the heat preservation impact parameters specifically includes:

[0026] Obtain the thermal insulation impact coefficient of the vehicle, and determine the continuous thermal insulation time of the fuel thermal insulation control system based on the thermal insulation impact parameter using the following formula:

[0027] t(i)=Cn*[E+Tq(i)*[Qn(i)-0.65*Qe(i)]]*K -1

[0028] Where t(i) represents the continuous heat preservation time at a certain moment i, Cn represents the vehicle start-stop frequency, E represents the photovoltaic power generation, Tq(i) represents the influence coefficient of ambient temperature on battery power, Qn(i) represents the actual battery power, Qe(i) represents the nominal battery capacity, and K represents the vehicle fuel tank heat dissipation rate.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0051] like Figure 1 As shown in the embodiment of this application, a fuel oil temperature control method includes:

[0052] S101: Obtain the operating parameters corresponding to the vehicle's battery, and determine whether the vehicle needs to perform photovoltaic power replenishment operation based on the operating parameters.

[0053] To address the difficulty of engine starting in low-temperature environments due to factors such as low temperature and fuel waxing, this application provides a fuel temperature control method based on existing vehicle preheating systems. This method is applied to the vehicle's built-in fuel temperature control system, aiming to improve engine starting performance in low-temperature conditions while reducing fuel consumption. It should be noted that the embodiments of this application are particularly applicable to photovoltaic power generation vehicles.

[0054] In this embodiment, the vehicle has a built-in photovoltaic power generation module. Under the control of the fuel temperature control system, the insulated fuel tank can receive energy from the photovoltaic power generation module in addition to the energy provided by the battery and onboard generator. The insulated fuel tank has a heating function; an insulation layer is added to the outside of the tank. Under specific low-temperature conditions, the energy obtained through this method continuously heats and keeps the fuel warm, effectively reducing heat loss and preventing fuel wax formation.

[0055] The battery serves as the main power supply module when the vehicle starts. When the battery charge is insufficient, the onboard alternator charges the battery, and the photovoltaic module provides auxiliary charging. Therefore, to determine whether a vehicle needs photovoltaic charging, the operating parameters of the vehicle's battery must first be obtained. Based on these parameters, it is determined whether photovoltaic charging is required. These operating parameters include the battery voltage and the charging current after the vehicle starts. The system checks whether the voltage is lower than a preset voltage and whether the charging current is higher than a preset current. If the voltage is lower than the preset voltage or the charging current is higher than the preset current, it is determined that photovoltaic charging is required. The preset voltage can be -26.5V, and the preset current can be 5A. These values ​​are merely examples; specific values ​​can be set according to the actual battery model and capacity, and this application does not limit them.

[0056] S102: If yes, then obtain the vehicle's onboard information and determine whether the speed in the onboard information is greater than the preset speed, so as to determine the vehicle's status; wherein, the vehicle status includes the vehicle's off state and the vehicle's onboard state, and the onboard information includes the vehicle's speed, fuel level and temperature.

[0057] The vehicle's power supply mode varies depending on its operating state. When the vehicle is off, to prevent fuel wax buildup in low-temperature environments, the insulated fuel tank's heating function is used to raise the fuel temperature. In this case, the insulated fuel tank's energy is primarily provided by the photovoltaic power generation module, with the vehicle's battery providing auxiliary power. When the vehicle is running, the insulated fuel tank does not need to insulate the fuel; the onboard alternator charges the battery, and the photovoltaic power generation module provides auxiliary charging. Therefore, when the battery charge is low, the vehicle's status needs to be further assessed to determine whether fuel insulation is necessary.

[0058] Vehicle status can be determined by onboard information connected to the vehicle's bus. After acquiring the vehicle's onboard information, it is determined whether the engine speed is greater than a preset speed to determine the vehicle's status. Vehicle status includes both engine-off and engine-on states. Onboard information includes engine speed, fuel level, and temperature. The preset engine speed is 500 rpm. When the engine speed is greater than 500 rpm, the vehicle status is determined to be in the engine-on state; when the engine speed is less than 500 rpm, the vehicle status is determined to be in the engine-off state.

[0059] S103: When the vehicle is in the started state, the vehicle is charged by the photovoltaic power generation module built into the vehicle, so that the battery can be charged by the photovoltaic power generation module.

[0060] When the vehicle is in the started state, it is necessary to reconfirm whether the actual battery charge is insufficient. If so, the vehicle needs to be charged by the built-in photovoltaic power generation module to assist in charging the battery.

[0061] S104: When the vehicle is in the off state, acquire the vehicle's heat preservation influence parameters, determine the continuous heat preservation time of the fuel heat preservation control system based on the heat preservation influence parameters, and perform heat preservation control on the fuel heat preservation control system based on the continuous heat preservation time.

[0062] When the vehicle is off, the fuel tank, which is designed to maintain fuel temperature, needs to be kept warm. At this time, the duration of the fuel temperature control system's maintenance needs to be evaluated to determine how long the vehicle's battery can maintain this temperature under the current ambient temperature, battery charge, and other factors. This requires obtaining the vehicle's temperature control parameters. Based on these parameters, the duration of the fuel temperature control system's maintenance needs to be determined, and the system can then be adjusted accordingly to maintain the desired temperature.

[0063] Specifically, the continuous heat preservation time of the fuel heat preservation control system is determined using the following formula based on the heat preservation influence parameters:

[0064] t(i)=Cn*[E+Tq(i)*[Qn(i)-0.65*Qe(i)]]*K -1

[0065] Where t(i) represents the continuous heat preservation time at a certain moment i, Cn represents the vehicle start-stop frequency, E represents the photovoltaic power generation, Tq(i) represents the influence coefficient of ambient temperature on battery charge, Qn(i) represents the actual battery charge, Qe(i) represents the nominal battery capacity, and K represents the vehicle fuel tank heat dissipation rate, which is affected by ambient temperature Tc(i), fuel temperature Td(i), and fuel quantity Vt(i).

[0066] After obtaining the continuous heat preservation time of the fuel heat preservation control system at the current moment, the continuous heat preservation time is compared with the preset first heat preservation time to determine the relationship between the two.

[0067] If the continuous heat preservation time exceeds the first heat preservation time, the fuel heat preservation control system will be activated to maintain fuel temperature. During this process, the real-time continuous heat preservation time of the fuel heat preservation control system will be determined. Then, this real-time continuous heat preservation time will be compared with a preset second heat preservation time. If the real-time continuous heat preservation time is less than the second heat preservation time, the fuel heat preservation control system will stop maintaining fuel temperature. The second heat preservation time can be set to 1 hour or 2 hours. In other words, if the continuous heat preservation time exceeds 2 hours, the fuel heat preservation control system will activate the fuel tank to maintain fuel temperature until the continuous heat preservation time is less than 1 hour, at which point it will stop to prevent the vehicle from starting due to low battery.

[0068] If the continuous heat preservation time is less than the first heat preservation time, the continuous heat preservation time is compared with the second heat preservation time. If the continuous heat preservation time is less than the second heat preservation time, the fuel heat preservation control system is controlled to stop the fuel heat preservation operation.

[0069] It should be noted that when the real-time continuous heat preservation time is less than the first heat preservation time, the vehicle will issue a heat preservation warning to indicate that the vehicle will stop fuel warming operation within a preset time period. The preset time period represents the time difference between the real-time continuous heat preservation time and the second heat preservation time. By monitoring the remaining real-time continuous heat preservation time and issuing heat preservation warnings, the driver can be prompted to take appropriate measures to avoid the problem of insufficient vehicle battery due to excessive heat preservation time.

[0070] In one embodiment, before evaluating the continuous heat preservation time of the fuel heat preservation control system, it is necessary to determine whether the vehicle is currently in a low-temperature environment by using the fuel temperature and ambient temperature. If the temperature is not high enough to make the vehicle difficult to start, the fuel heat preservation control system does not need to perform fuel heat preservation work.

[0071] Specifically, ambient temperature and fuel temperature are collected by ambient temperature and fuel temperature sensors installed on the vehicle. These temperatures are then compared with their corresponding preset temperatures to determine the corresponding continuous heat preservation time evaluation mode for the fuel heat preservation control system. The continuous heat preservation time evaluation mode includes a first evaluation mode and a second evaluation mode. The first evaluation mode primarily assesses whether the vehicle needs to perform fuel heat preservation and for how long, while the second evaluation mode assesses whether the vehicle needs to immediately stop the fuel heat preservation process.

[0072] When the ambient temperature or fuel temperature is lower than its corresponding preset temperature, the vehicle is in a low-temperature environment. At this time, the continuous heat preservation time evaluation mode is determined as the first evaluation mode. Based on the first evaluation mode, the relationship between the continuous heat preservation time and the first heat preservation time is determined. Then, through the judgment method described above, it is determined whether the fuel heat preservation control system should perform fuel heat preservation operation.

[0073] Otherwise, it indicates that the vehicle's current environment does not require fuel warming. In this case, the continuous warming time assessment mode is set to the second assessment mode. Based on the second assessment mode, the relationship between the continuous warming time and the second warming time is determined to decide whether the fuel warming control system should stop the fuel warming operation. If the continuous warming time is less than the second warming time, the fuel warming operation can be stopped directly. If the continuous warming time is not less than the second warming time, the vehicle's current state needs to be reassessed to determine whether the vehicle still needs to continue fuel warming.

[0074] It should be noted that after the fuel insulation control system stops the fuel insulation operation, it is necessary to reacquire the vehicle's battery operating parameters and determine whether the vehicle needs to perform photovoltaic charging based on the operating parameters to ensure that the battery has sufficient power.

[0075] Figure 2 A schematic flowchart of another fuel heat preservation control method provided in this application embodiment is shown below. Figure 2As shown, after the fuel temperature control system is initialized, it determines whether the battery needs photovoltaic charging based on the battery's operating parameters. If so, the vehicle status needs to be further determined based on the engine speed. When the engine speed is higher than the preset speed, since the battery does not need to provide energy for fuel temperature control, photovoltaic charging can be directly applied to the battery. When the engine speed is lower than the preset speed, it indicates that the vehicle is off. After determining that the fuel tank is in a fuel temperature control state based on the temperature, the continuous temperature control time is evaluated. If the continuous temperature control time is greater than the first temperature control time (e.g., t>2h), the fuel temperature control is directly activated. If the continuous temperature control time is less than the second temperature control time (e.g., t<1h), the fuel temperature control is stopped, and the actual battery charge is then detected to determine whether photovoltaic charging is needed. When the temperature determines that the fuel tank does not need to perform fuel insulation, and when the continuous insulation time obtained from the insulation effect parameters is not greater than the first insulation time, the continuous insulation time obtained at the corresponding time is compared with the second insulation time. Once the continuous insulation time is less than the second insulation time, the fuel insulation operation can be stopped directly.

[0076] Figure 3 This is a schematic diagram of the architecture of a fuel oil temperature control system provided in an embodiment of this application. The fuel oil temperature control system includes a photovoltaic power generation module, an energy control module, and a temperature-insulating fuel tank.

[0077] In the fuel insulation control system, the energy control module employs an insulation control strategy, combining power generation capacity, ambient temperature, battery capacity, fuel capacity, and other vehicle information. Through the main control logic, it calculates the insulation time limit and sends this time limit to the driver as a reminder. It also has power distribution capabilities, providing on-demand power from the photovoltaic power generation module and the vehicle's alternator to the fuel insulation control system, while simultaneously providing supplemental power to the vehicle's battery. The photovoltaic power generation module outputs photovoltaic-converted electrical energy, which is transmitted to the energy control module via a dedicated wiring harness. The energy control module then distributes this energy to supplement the insulation-functional fuel tank and the vehicle's battery. The insulation-functional fuel tank features a heating function, with an added insulation layer on the outside. Under specific low-temperature conditions, continuous heating and the insulation layer effectively reduce heat loss and prevent fuel wax formation.

[0078] The energy control module is used to obtain the operating parameters of the vehicle's battery and determine whether the vehicle needs to perform photovoltaic power replenishment based on the operating parameters.

[0079] If so, the vehicle's onboard information is obtained, and it is determined whether the speed in the onboard information is greater than the preset speed, so as to determine the vehicle's status; wherein, the vehicle status includes the vehicle's off state and the vehicle's on state, and the onboard information includes the vehicle's speed, fuel level and temperature.

[0080] When the vehicle is in the started state, the photovoltaic power generation module performs a photovoltaic power supplement operation on the vehicle, so that the battery can be charged under the power supplement operation of the photovoltaic power generation module;

[0081] When the vehicle is in a turned-off state, the vehicle's heat preservation impact parameters are obtained. Based on the heat preservation impact parameters, the continuous heat preservation time of the fuel heat preservation control system is determined, and the fuel heat preservation control system is controlled according to the continuous heat preservation time.

[0088] When the vehicle is in the started state, the vehicle's built-in photovoltaic power generation module performs photovoltaic power supplementation operation to enable the battery to be charged under the power supplementation operation of the photovoltaic power generation module;

[0089] When the vehicle is in a turned-off state, the vehicle's heat preservation impact parameters are obtained. Based on the heat preservation impact parameters, the continuous heat preservation time of the fuel heat preservation control system is determined, and the fuel heat preservation control system is controlled according to the continuous heat preservation time.
