Example 1
In order to avoid the situation that the engine cannot be started due to the freezing of diesel oil in a low-temperature environment, diesel oil with different labels is usually filled, but a driver is usually required to manually switch the oil supply mode according to the environment temperature, so that the operation is inconvenient, and misoperation can be caused due to misjudgment of the driver. In this regard, the prior art provides a method for switching fuel from a different grade tank by detecting the ambient temperature, and if the ambient temperature is low, the engine uses low grade diesel and heats the high grade tank; if the detected environment temperature is higher or the detected fuel temperature of the high-grade fuel tank reaches the requirement in the process of heating the high-grade fuel tank, the engine uses the high-grade diesel. However, there is still a problem in that low grade diesel oil may be solidified as well when a vehicle is driven in an extremely low temperature environment, and costs are increased if diesel oil having a lower solidification point is injected.
In view of the above problems, the present embodiment provides a control method of an oil supply system, so as to solve the problem that in the prior art, when a vehicle runs in an extremely low temperature environment, low-grade diesel oil may be solidified, and if diesel oil with a lower solidification point is added, the cost is increased, and the control method can be used in the technical field of vehicles. The oil supply system control method may be performed by an oil supply system control device that may be implemented in software and/or hardware and integrated in a vehicle.
The oil supply system comprises a first oil tank for storing high-grade diesel oil and a second oil tank for storing low-grade diesel oil, the condensation point of the high-grade diesel oil is at a first temperature, the condensation point of the low-grade diesel oil is at a second temperature, the first temperature is higher than the second temperature, and the second oil tank is provided with a low-grade diesel oil heater for heating oil. In an extremely low temperature environment, the low-grade diesel oil in the second oil tank can be heated by the low-grade diesel oil heater, so that the temperature of the low-grade diesel oil is increased, and the normal oil supply can be realized after the temperature is higher than the condensation point. In addition, the first oil tank is provided with a high-grade diesel heater for heating oil, and the high-grade diesel heater is used for heating high-grade diesel.
Referring to fig. 1, the oil supply system control method includes the following steps.
S100: the ambient temperature is obtained.
The ambient temperature may be detected by an ambient temperature sensor provided to the vehicle body, and the detected ambient temperature may be transmitted to the controller.
S110: comparing the magnitude of the ambient temperature with the second temperature.
If the ambient temperature is not greater than the second temperature, step S120 is performed; if the ambient temperature is greater than the second temperature, steps S130-S140 are performed.
S120: and determining that the low-grade diesel heater is started, and determining that the oil supply system stops supplying oil to the engine.
If the ambient temperature is not higher than the second temperature, the ambient temperature is lower at the moment and is lower than the condensation point of the low-grade diesel oil in the second oil tank, and the vehicle cannot be started normally at the moment, so that the low-grade diesel oil heater is determined to be started to heat the low-grade diesel oil, and the temperature of the low-grade diesel oil is increased to be higher than the second temperature as soon as possible. Meanwhile, the diesel oil in the two oil tanks of the vehicle cannot meet the requirement of the use temperature at the moment, so that the oil supply system stops supplying oil to the engine.
S130: and acquiring the oil temperature of the second oil tank.
The oil temperature of the second oil tank can be detected by a temperature sensor arranged in the second oil tank, and the detected oil temperature of the second oil tank is sent to the controller.
S140: and comparing the oil temperature of the second oil tank with the second temperature.
If the oil temperature of the second oil tank is not greater than the second temperature, executing step S120; if the oil temperature of the second oil tank is greater than the second temperature, step S150 is performed.
When the ambient temperature is greater than the second temperature, the oil temperature of the second oil tank still cannot ensure that the second temperature has been reached, and there may be a case where the ambient temperature is higher, but the oil temperature of the oil tank is still lower, so if it is detected that the oil temperature of the second oil tank is not greater than the second temperature, step S120 is still performed to heat the low-grade diesel.
Alternatively, after step S120 is performed, step S130 is performed.
After the low-grade diesel oil is heated, detecting the oil temperature of the second oil tank, if the oil temperature of the second oil tank reaches the second temperature, that is, in step S140, the oil temperature of the second oil tank is greater than the second temperature, executing step S150, and if the oil temperature of the second oil tank is still not greater than the second temperature, continuing to repeat step S120.
In step S120, if the low-grade diesel heater is not already turned on, turning on the low-grade diesel heater; if the low-grade diesel heater is started, the starting state of the low-grade diesel heater is maintained unchanged. If the oil supply system is in a state of supplying oil to the engine, particularly, an electromagnetic valve between the oil supply system and the engine is opened, the electromagnetic valve is cut off, and the oil supply system is controlled to stop supplying oil to the engine; if the fuel supply system is already in a state of stopping the fuel supply to the engine at this time, the state is maintained.
S150: the magnitude of the ambient temperature is compared to the first temperature.
If the ambient temperature is not greater than the first temperature, step S160 is performed.
S160: and determining that the high-grade diesel heater is started, determining that the low-grade diesel heater is closed, and determining that the second oil tank supplies oil to the engine.
If the ambient temperature is not higher than the first temperature, the ambient temperature is lower than the condensation point of the high-grade diesel oil, so that the high-grade diesel oil heater needs to be determined to be started to heat the high-grade diesel oil.
In the oil supply system control method provided by the embodiment, the environmental temperature is obtained, the environmental temperature is compared with the second temperature, if the environmental temperature is not greater than the second temperature, the environmental temperature is lower than the condensation point of the low-grade diesel oil, at the moment, the vehicle is in an extremely low-temperature environment, the diesel oil is easy to solidify, and the engine is stopped to be started, so that the low-grade diesel oil heater is determined to be started to heat the low-grade diesel oil, and the oil supply system is determined to stop supplying oil to the engine. If the ambient temperature is higher than the second temperature, the ambient temperature meets the use temperature requirement of low-grade diesel oil, then the oil temperature of the second oil tank is obtained, the oil temperature of the second oil tank is compared with the second temperature, if the oil temperature of the second oil tank is higher than the second temperature, the ambient temperature is compared with the first temperature, after the temperature of the low-grade diesel oil exceeds the condensation point of the low-grade diesel oil, whether the current ambient temperature meets the use requirement of high-grade diesel oil is further judged, if the ambient temperature is not higher than the first temperature, the ambient temperature is lower than the condensation point of the high-grade diesel oil, so that the high-grade diesel oil heater is determined to be started, the low-grade diesel oil heater is determined to be closed, the second oil tank is determined to supply oil for an engine, the high-grade diesel oil is heated, the low-grade diesel oil is stopped being heated, and the low-grade diesel oil is provided for the engine through the second oil tank, so that the starting requirement of the engine is met.
Optionally, in step S150, if the ambient temperature is greater than the first temperature, steps S170-S180 are performed.
S170: and acquiring the oil temperature of the first oil tank.
If the ambient temperature is higher than the first temperature, the ambient temperature is higher at the moment, and the temperature requirement of high-grade diesel oil can be met, so that whether the oil liquid temperature of the first oil tank is higher than the first temperature is further judged. The oil temperature of the first oil tank can be detected by a temperature sensor arranged on the first oil tank, and the detected oil temperature of the first oil tank is sent to the controller.
S180: and comparing the oil temperature of the first oil tank with the first temperature.
If the oil temperature of the first oil tank is not greater than the first temperature, executing step S160; if the oil temperature of the first oil tank is greater than the first temperature, step S190 is performed.
When the ambient temperature is higher, there is still a case that the oil temperature of the first oil tank is not greater than the first temperature, that is, the temperature of the high-grade diesel is lower than the condensation point of the high-grade diesel, so if the oil temperature of the first oil tank is not greater than the first temperature, step S160 is executed to heat the high-grade diesel.
Alternatively, after step S160 is performed, step S170 is performed.
After heating the high-grade diesel, detecting the oil temperature of the first oil tank, if the oil temperature of the first oil tank reaches the first temperature, that is, in step S180, the oil temperature of the first oil tank is greater than the first temperature, executing step S190, and if the oil temperature of the first oil tank is still not greater than the first temperature, continuing to repeat step S160.
In step S160, if the Gao Biaohao diesel heater is not already turned on, turning on the high-grade diesel heater; if the Gao Biaohao diesel heater is already on, the on state of the high-grade diesel heater is maintained unchanged. If the low-grade diesel heater is started, the low-grade diesel heater is closed; if the low-grade diesel heater is not started, the off state of the low-grade diesel heater is maintained unchanged. If the second oil tank is not used for supplying oil to the engine, namely, the electromagnetic valve between the second oil tank and the engine is closed, the electromagnetic valve is opened, so that the second oil tank is used for supplying oil to the engine; if the second tank is already in a state of supplying oil to the engine, the state is maintained.
S190: and determining that the high-grade diesel heater and the low-grade diesel heater are both closed, determining that the second oil tank stops supplying oil to the engine, and controlling the first oil tank to supply oil to the engine.
If the oil temperature of the first oil tank is higher than the first temperature, the high-grade diesel oil of the first oil tank also meets the requirement of the using temperature, so that the high-grade diesel oil heater and the low-grade diesel oil heater are both determined to be closed, and the second oil tank is determined to stop supplying oil to the engine. Meanwhile, the first oil tank is controlled to supply oil to the engine, and the running cost can be reduced due to the high cost of low-grade diesel oil.
In step S190, if the Gao Biaohao diesel heater or the low-grade diesel heater is not already turned on, maintaining the turned-off state; if Gao Biaohao diesel heater or low grade diesel heater is already on, then turn off the high grade diesel heater or low grade diesel heater. If the second oil tank is in a state of supplying oil to the engine, namely, the electromagnetic valve between the second oil tank and the engine is opened, the electromagnetic valve is closed, so that the second oil tank stops supplying oil to the engine; if the second oil tank is not yet supplying oil to the engine, the state is maintained.
