Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a first aspect, the embodiment of the invention provides a drinking water control method for a passenger vehicle.
In an embodiment, referring to fig. 1, fig. 1 is a schematic flow chart of a drinking water control method for a passenger vehicle according to a first embodiment of the present invention. As shown in fig. 1, the drinking water control method for a passenger car includes:
step S10, detecting whether a target temperature is received;
in the embodiment, the passenger may have a drinking water demand in the process of riding the vehicle, and when the passenger has the drinking water demand, the passenger sends out a drinking request, wherein the drinking request is realized by clicking a function key on the vehicle. The drinking request includes a target temperature set by the passenger, namely the temperature of the water required to be drunk by the passenger. And the VCU of the vehicle control unit is responsible for detecting whether the target temperature is received.
Step S20, if the target temperature is received, calculating the difference value between the target temperature and the temperature of the drinking water in the water tank to obtain a temperature difference, and detecting whether the temperature difference is greater than a threshold value;
in this embodiment, when it is detected that the target temperature is received, a difference between a demand of the customer and an actual situation needs to be analyzed, specifically, a difference between the target temperature and a temperature of drinking water in the water tank is calculated, and whether the difference is greater than a threshold value is determined. If the difference value is larger than the threshold value, the temperature of the drinking water in the water tank is lower than the temperature required by passengers, and the drinking water in the water tank needs to be heated; if the difference value is smaller than the threshold value, the temperature of the drinking water in the water tank is higher than the temperature required by a customer, and the drinking water in the water tank needs to be cooled; if the difference is equal to the threshold value, the temperature of the drinking water in the water tank is the same as the temperature required by passengers, and the drinking water outlet of the water tank can be directly controlled without cooling or heating treatment.
Step S30, if the temperature difference is larger than the threshold value, detecting whether the engine is started;
in this embodiment, if the difference is greater than the threshold value, it indicates that the temperature of the drinking water in the water tank is lower than the temperature required by the passenger, and the drinking water in the water tank needs to be heated. In order to realize the function that the passenger vehicle can heat the drinking water in the water tank when the engine does not work, whether the engine works or not needs to be detected, and different heating strategies are adopted according to the condition that whether the engine works or not.
And step S40, if the engine is not started, the heater is started, the three-way proportional valve is controlled to be connected with the heating loop, the water pump enables the drinking water to flow into the heat exchanger, and meanwhile, the heating device of the heat exchanger is used for heating the drinking water until the temperature of the drinking water reaches the target temperature.
In this embodiment, if the engine of the passenger car is found to be not working after detection, the heater needs to be turned on, and the drinking water is heated by the heater. The water pump is connected in proportion by the tee joint before heating, so that the drinking water flows into the water pump, and the drinking water in the water pump is heated by the heater conveniently. The heating of the drinking water is a continuous process, which is continued until the temperature of the drinking water reaches the temperature demanded by the passengers.
The working principle of the heater (PTC) means that after the PTC heating piece is electrified, the resistance value is increased to enter a jump zone by self-heating, the surface temperature of the PTC heating piece keeps a constant value, and the temperature is only related to the Curie temperature and the applied voltage of the PTC heating piece and is basically unrelated to the ambient temperature. Even in the case of abnormal operation, the input power can be reduced very low due to the regulation action of the PTC element itself, and no unexpected situation occurs. The operation principle of the heater (PTC) can also be described as that the constant temperature heating PTC thermistor has constant temperature heating characteristic, and the principle is that after the PTC thermistor is powered on, the resistance value is heated by self-heating to enter a jump zone, and the surface temperature of the constant temperature heating PTC thermistor can be kept at a constant value, and the temperature is only related to the curie temperature and the applied voltage of the PTC thermistor, and is not basically related to the ambient temperature. The PTC heater is a heating device designed by utilizing the constant temperature heating characteristic of the constant temperature heating PTC thermistor. In the middle and small power heating occasions, the PTC heater has the advantages of constant temperature heating, no open fire, high heat conversion rate, little influence of power supply voltage, long natural life and the like which cannot be compared with the traditional heating element, and the application of the PTC heater in an electric heating appliance is more and more favored by research and development engineers. The constant temperature heating PTC thermistor can be manufactured into various shapes and structures and different specifications, and is commonly in a disc shape, a rectangle shape, a strip shape, a circular ring shape, a honeycomb porous shape and the like. The PTC heating element and the metal component are combined to form various forms of high-power PTC heaters.
Further, in an embodiment, after the step of detecting whether the engine is started if the temperature difference is greater than the threshold, the method further includes:
if the engine is started, the three-way proportional valve is controlled to be communicated with a water chamber of an engine exhaust system, so that drinking water flows into the water pump, and meanwhile, the engine exhaust system is utilized to heat the drinking water until the temperature of the drinking water reaches the target temperature.
In this embodiment, if the engine of the passenger vehicle is found to be already operating after the detection, the heating strategy of the engine in the operating state can be used. At the moment, the heater is not started because the engine is started, the vehicle control unit controls the three-way valve to be directly communicated with the water chamber of the engine exhaust system and then flows into the water pump to control the water pump to start working, meanwhile, the internal water path circulation of the drinking water system is started, and the engine exhaust system is continuously utilized to heat the drinking water until the temperature of the drinking water reaches the target temperature.
Further, in an embodiment, after the step of detecting whether the temperature difference is greater than the threshold value, the method further includes:
if the temperature difference is smaller than the threshold value, the air conditioner compressor is started, the three-way proportional valve is connected with the refrigerating loop, the water pump controls the drinking water to flow through the heat exchanger, and meanwhile, the condensing device of the heat exchanger is used for refrigerating the drinking water until the temperature of the drinking water reaches the target temperature.
In this embodiment, if the difference is smaller than the threshold, it indicates that the temperature of the drinking water in the water tank is higher than the temperature required by the customer, and the drinking water in the water tank needs to be cooled. The method comprises the specific steps that a vehicle control unit controls a three-way valve to be directly communicated with a water pump and controls the water pump to start working, meanwhile, a water path inside a drinking water system is started to circulate, the vehicle control unit controls an air conditioner compressor to start working, the cooling function is achieved through heat dissipation of a condenser and heat absorption of an evaporator, and the air conditioner compressor can stop working until the temperature of drinking water is reduced to a target temperature.
The air conditioner compressor for vehicle has two main types, such as fixed displacement compressor, and the displacement of the fixed displacement compressor is increased proportionally with the increase of the rotating speed of the engine, so that the power output cannot be automatically changed according to the refrigeration requirement, and the influence on the oil consumption of the engine is large. The control of the fixed displacement compressor is generally realized by acquiring a temperature signal of an air outlet of the evaporator, and when the temperature reaches a set temperature, the electromagnetic clutch of the compressor is released, and the compressor stops working. When the temperature rises, the electromagnetic clutch is combined, and the compressor starts to work. The constant displacement compressor is also controlled by the pressure of the air conditioning system, and when the pressure in the pipeline is overhigh, the compressor stops working. For another example, the variable displacement air conditioner compressor can automatically adjust the power output according to the set temperature. The air conditioner control system does not collect the temperature signal of the air outlet of the evaporator, but controls the compression ratio of the compressor according to the change signal of the pressure in the air conditioner pipeline to automatically adjust the temperature of the air outlet. The compressor is always operated during the whole process of refrigeration, and the adjustment of the refrigeration intensity is completely controlled by a pressure regulating valve arranged inside the compressor. When the pressure at the high-pressure end in the air-conditioning pipeline is too high, the pressure regulating valve shortens the stroke of the piston in the compressor to reduce the compression ratio, so that the refrigeration intensity is reduced. When the pressure at the high pressure end is reduced to a certain degree and the pressure at the low pressure end is increased to a certain degree, the pressure regulating valve increases the stroke of the piston so as to improve the refrigeration intensity.
Further, in an embodiment, after the step of detecting whether the temperature difference is greater than the threshold value, the method further includes:
and if the temperature difference is equal to the threshold value, controlling the water outlet of the water drinking port.
In this embodiment, if the difference equals the threshold value, it indicates that the temperature of drinking water in the water tank is the same with the temperature of passenger's demand this moment, need not do the processing of cooling or heating, can directly control the drinking water mouth of water tank and go out water.
Further, in an embodiment, after the step of detecting whether the target temperature is received, the method further includes:
if the target temperature is not received, detecting the temperature of the drinking water in the water tank;
if the temperature of the drinking water in the water tank is not higher than the preset temperature, detecting whether the time for not receiving the target temperature is not shorter than a first preset time;
if the time that the passenger does not have the drinking water requirement is not less than the first preset time, opening the drainage valve, and injecting the drinking water in the pipeline into the water tank by using the water pump for heat preservation;
if the time that the passenger has no drinking water requirement is less than a first preset time, no treatment is carried out;
if the temperature of the drinking water in the water tank is higher than the preset temperature, detecting whether the time of no drinking water demand of passengers is not shorter than a second preset time;
if the time that the passenger does not have the drinking water requirement is not less than the second preset time, the leakage valve is opened, and the drinking water in the pipeline is injected into the water tank by the water pump for heat preservation;
if the time that the passenger has no drinking water requirement is less than the second preset time, the passenger does not process the drinking water.
In this embodiment, if the target temperature is not received, it indicates that the passenger has no need for drinking water temporarily, but the temperature of the drinking water in the water tank can be kept within a reasonable range, i.e. the water temperature cannot be too low. The temperature of drinking water in the vehicle control unit can detect the water tank, if drinking water temperature is not more than preset the temperature in the water tank, shows that drinking water temperature is on the low side in the water tank this moment, needs keep warm, and the difference of presetting the temperature according to particular case can be set to different values. And then detecting whether the time when the vehicle does not receive the target temperature is not less than a first preset time, if the time when the passenger does not have the drinking water requirement is not less than the first preset time, the vehicle controller opens the drain valve, and the drinking water in the pipeline is injected into the water tank by using the water pump for heat preservation. If the time that the passenger does not have the drinking water requirement is less than the first preset time, the system does not process, because the duration time that the passenger does not have the drinking water requirement is in the whole vehicle range, the heat preservation operation is not needed. The first preset time length is set to different values according to different situations. If the temperature of the drinking water in the water tank is higher than the preset temperature, whether the time for which the passenger has no drinking water demand is not shorter than a second preset time period or not needs to be detected; if the time that the passenger does not have the drinking water demand is not less than the second preset duration, the drain valve is opened, and the drinking water in the pipeline is injected into the water tank by the water pump for heat preservation treatment. If the time of no drinking water demand of the passengers is less than the second preset time period, no treatment is carried out. The second preset duration is set to a different value according to different specific situations, and the first preset market must be smaller than the second preset duration.
The first embodiment of the invention relates to a drinking water control method for a passenger vehicle, which comprises the following steps: detecting whether a target temperature is received; if the target temperature is received, calculating the difference value between the target temperature and the temperature of the drinking water in the water tank to obtain a temperature difference, and detecting whether the temperature difference is greater than a threshold value; if the temperature difference is larger than a threshold value, detecting whether the engine is started; if the engine is not started, the heater is started, the three-way proportional valve is controlled to be connected with the heating loop, the water pump enables the drinking water to flow into the heat exchanger, and meanwhile the heating device of the heat exchanger is used for heating the drinking water until the temperature of the drinking water reaches the target temperature.
