Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In order to be able to better understand the solution of the present application, a lower vehicle seat temperature control system is first described here. The vehicle type of this application includes pure electric vehicle type and hybrid vehicle type, and pure electric vehicle type mainly relies on the battery to provide power, and hybrid vehicle type can rely on the battery and increase the journey ware and provide power simultaneously, therefore pure electric vehicle type and the corresponding car seat temperature regulation system of hybrid vehicle type can be different slightly.

Further, in consideration of the fact that the heating requirements of members in the cabin are different in practical application, the seat temperature control pipeline 2 further comprises a second multi-way electromagnetic valve 306, the channels of the second multi-way electromagnetic valve 306 can be determined based on practical situations, each channel is correspondingly communicated with each temperature control pipeline, and the corresponding temperature control pipeline can be heated independently. And, still be provided with corresponding radiator fan below every seat control by temperature change pipeline, when cooling down the seat, steerable radiator fan opens.

The second multi-way electromagnetic valve 306 may be a six-way electromagnetic valve, the passage ports are respectively Y1, Y2, Y3, Y4, Y5 and Y6, Y1 is connected to the main pipe of the seat temperature control pipeline 2, and Y2, Y3, Y4, Y5 and Y6 are respectively connected to the temperature control pipeline 301 of the main driver seat, the temperature control pipeline 302 of the front driver seat, the temperature control pipeline 303 of the rear seat, the temperature control pipeline 304 of the carpet, and the temperature control pipelines 305 at other positions.

When the motorcycle type is pure electric vehicle type or mixed motor vehicle type, battery circuit D all includes: a battery 29, a battery cooler 30 and a battery water pump 31.

When the temperature of the seat is adjusted, the seat can be heated, and the seat can also be cooled. When the heating mode is a normal heating mode, the controller can be used for controlling the seat temperature control pipeline 3 to be merged into the warm air loop A through the first multi-way electromagnetic valve 1, and heat in the warm air loop A is used for providing a heat source for the seat temperature control pipeline 3; the seat temperature control pipelines 3 are laid below the seats in the cabin in parallel;

if the heating mode is the energy-saving heating mode, the controller can be used for controlling the seat temperature control pipeline 3 to be connected in series to the motor cooling loop B through the first multi-way electromagnetic valve 1, the seat temperature control pipeline 3 is disconnected from the warm air loop A through the first multi-way electromagnetic valve 1, and heat in the motor cooling loop B provides a heat source for the seat temperature control pipeline 3. The controller may be a vehicle controller of a vehicle.

That is, in the normal heating mode, the warm air pump 6 serves as a power source for seat temperature adjustment, and the PTC in the warm air circuit a serves as a main heat source. Meanwhile, for a pure electric vehicle, the heat exchange between the WCDC of the water-cooled condenser and the air-conditioning loop C is used as an auxiliary heat source; for a hybrid vehicle type, the cooling water of the range extender 10 is used as an auxiliary heat source, and the seat temperature control pipeline 3 can be rapidly heated.

In the seat refrigeration mode, a controller can be used for controlling a seat temperature control pipeline to be merged into a warm air loop A through a first multi-way electromagnetic valve 1; and controlling a heater PTC in the warm air loop to be closed;

when the vehicle is a pure electric vehicle, controlling high-temperature refrigerants output by an air-conditioning compressor to sequentially enter an outdoor heat exchanger and a gas-liquid separator in an air-conditioning loop to obtain low-temperature refrigerants, and controlling the low-temperature refrigerants to flow into a water-cooled condenser 4 in a warm air loop A; the low-temperature refrigerant is used for cooling the cooling liquid in the water-cooled condenser 4, and the cooled cooling liquid enters the seat temperature control pipeline 3.

That is, in the cooling mode, the refrigerant direction is controlled by the electronic stop valve in the air-conditioning loop, so that the low-temperature refrigerant passing through the outdoor heat exchanger 18 of the pure electric vehicle type and the condenser 28 of the hybrid vehicle type flows through the water-cooled condenser 4, and fully exchanges heat with the cooling liquid of the seat temperature control pipeline 3 to obtain the low-temperature cooling liquid, and the seat cooling function is realized.

It should be noted that the specific implementation logic of the vehicle controller for adjusting the seat temperature will be described in detail in the following embodiment of the controller, and therefore will not be described herein again.

The whole temperature regulation system of this embodiment fully considers heating and refrigerated function realization and performance, and the design is coordinated again simultaneously and the whole car heat management principle is optimized, when realizing seat temperature regulation, still improves thermal management efficiency.

Based on the same inventive concept as the previous embodiment, the present embodiment further provides a method for adjusting the temperature of an automobile seat, which is applied to a vehicle controller, and as shown in fig. 4, the method includes the following steps:

s410, if the heating mode is a normal heating mode, controlling a seat temperature control pipeline to be merged into a warm air loop through a first multi-way electromagnetic valve, and providing a heat source for the seat temperature control pipeline by using heat in the warm air loop; the seat temperature control pipelines are laid below the seats in the cabin in parallel.

As described above, in the present embodiment, in order to improve the thermal management efficiency of the entire vehicle and reduce the seat temperature adjustment cost, different heating modes are set when the seat is heated, including the normal heating mode and the energy saving heating mode.

When a normal heating mode instruction of a user is received, the seat temperature control pipeline 2 is controlled to be merged into the warm air loop A through the first multi-way electromagnetic valve, and heat in the warm air loop A is utilized to provide a heat source for the seat temperature control pipeline 2.

Because the structures of the pure electric vehicle type and the hybrid electric vehicle type are different, the pure electric vehicle type only depends on the battery 29 to provide power, and the hybrid electric vehicle type can depend on the battery 29 and the range extender 24 to provide power, specific execution logics are different when the seat temperature control pipeline 2 is heated according to different vehicle types.

In one embodiment, then, the heat in the warm air circuit is used to provide a heat source for the seat temperature control circuit, comprising:

in a normal heating mode, when the vehicle is a pure electric vehicle, controlling a heater PTC in a warm air loop A to be started so as to heat cooling liquid in the warm air loop;

controlling a high-temperature refrigerant in an air conditioning loop to flow into a water-cooled condenser in a warm air loop so as to heat a cooling liquid flowing to the water-cooled condenser;

and controlling the cooling liquid in the warm air loop to flow into the seat temperature control pipeline after sequentially flowing through corresponding channels of the warm air water pump, the heater PTC, the water-cooled condenser and the first multi-way electromagnetic valve.

When the vehicle is a hybrid vehicle, the water-cooled condenser of the warm air loop is controlled to be closed, and the heater PTC5 is controlled to be opened;

the cooling liquid is controlled to flow through the range extender 24 and the PTC5 from the corresponding channel of the first multi-way electromagnetic valve 1 in two ways, and the cooling liquid is heated by the waste heat of the range extender 24 and the PTC5 and then flows into the seat temperature control pipeline.

Specifically, in the normal heating mode, the seat requires rapid heating, the warm air circuit a is heated, and the air conditioning circuit C is in the heat pump mode. The seat temperature control pipeline 2 is connected with the warm air loop A in parallel. In a normal heating mode, X1, X2 and X6 of the first multi-way solenoid valve 1 are communicated, (X1 is a cooling liquid inlet, and X2 and X6 are cooling liquid outlets); x4 is communicated with X5 (X4 is a cooling liquid inlet, X5 is a cooling liquid outlet), and X3 is closed.

For a pure electric vehicle, referring to fig. 5, the heater PTC5 and the water-cooled condenser 4 simultaneously provide a heat source for the seat temperature control line 2. In the warm air loop A, after flowing through the warm air water pump 6, the heater PTC5 and the water-cooled condenser 4, the cooling liquid enters the first multi-way electromagnetic valve 1 from X1, and part of the cooling liquid flows out from X2, passes through the temperature sensor 3 and the seat temperature control pipeline 2 and then flows back to the warm air water pump 6. The rest part of the cooling liquid flows out from the X6, passes through the warm air core body 9 and the first three-way electromagnetic valve 8, and then flows back to the warm air water pump 6.

And an air-conditioning heat pump in the air-conditioning loop C is started, and the water-cooled condenser 4 is used for carrying out auxiliary heating on the warm air loop A, so that the heating rate is increased. In the air-conditioning circuit C, the first electronic stop valve ELV41 is closed, the second electronic stop valve ELV42 and the third electronic stop valve ELV43 are opened, and the high-temperature refrigerant flows out from the air-conditioning compressor 17, passes through the ELV42, flows into the water-cooled condenser 4, and exchanges heat with the coolant of the water-cooled condenser 4 in the warm air circuit a, thereby performing auxiliary heating.

The cooling flow of the motor cooling circuit B is as follows:

the cooling liquid flows through the motor water pump 13, the four-way solenoid valve 12, the high-pressure assembly 11 and the driving motor 10, enters the first multi-way solenoid valve 1 from X4, flows out from X5, passes through the low-temperature radiator 16, and flows back to the motor water pump 13 to form circulation.

For a hybrid vehicle, referring to fig. 6, since the range extender 24 can generate waste heat, for the hybrid vehicle, the heater PTC5 and the range extender 24 are mainly used to provide a heat source for the seat temperature control pipeline 2. Specifically, the specific method of heating by using the PTC is the same as that of the pure electric vehicle, and is not described herein again.

The heat source provided by the range extender 24 is implemented as follows:

in the warm air circuit a, the coolant flows through the warm air water pump 6, the heater 5 and the water-cooled condenser 4, enters the first multi-way electromagnetic valve 1 from X1, and part of the coolant flows out from X2, passes through the temperature sensor 3 and the seat temperature control pipeline 2, and then flows back to the warm air water pump 6. The rest of the cooling liquid flows out from the X6, passes through the warm air core body 9, the range extender 24 and the first three-way electromagnetic valve 8, and then flows back to the warm air water pump 6.

The flow of the motor cooling circuit of the hybrid electric vehicle is the same as that of the pure electric vehicle, and is not described again.

Therefore, different seat temperature control adjusting strategies exist for different vehicle types, and the vehicle heat management efficiency can be improved to the maximum extent, so that the seat can be rapidly heated.

S411, if the heating mode is the energy-saving heating mode, controlling the seat temperature control pipeline to be connected in series to the motor cooling loop through the first multi-way electromagnetic valve, disconnecting the seat temperature control pipeline from the warm air loop through the first multi-way electromagnetic valve, and providing a heat source for the seat temperature control pipeline by using heat in the motor cooling loop.

When receiving the energy-saving heating mode instruction of a user, controlling the seat temperature control pipeline 2 to be connected in series to the motor cooling loop C through the first multi-way electromagnetic valve 1, disconnecting the seat temperature control pipeline 2 from the warm air loop A through the first multi-way electromagnetic valve 1, and providing a heat source for the seat temperature control pipeline 2 by using heat in the motor cooling loop.

In one embodiment, utilizing heat in a motor cooling circuit to provide a heat source for a seat temperature control circuit includes:

in the energy-saving heating mode, the electronic stop valve 7 of the warm air loop A is controlled to be disconnected;

controlling the cooling liquid of the motor cooling loop C to sequentially flow through the motor water pump 13, the four-way electromagnetic valve 12, the high-pressure assembly 11 and the driving motor 10 so as to heat the cooling liquid by utilizing the waste heat of the driving motor 10;

and controlling the heated cooling liquid to flow into the seat temperature control pipeline 2 through a corresponding channel of the first multi-way electromagnetic valve 1.

Specifically, the seat temperature control pipeline is connected in series with the motor cooling loop. In this mode, in the first multi-way electromagnetic valve 1, X1 and X6 are communicated (X1 is a coolant inlet and X6 is a coolant outlet), X2 and X4 are communicated (X4 is a coolant inlet and X2 is a coolant outlet), and X3 and X5 are communicated (X3 is a coolant inlet and X5 is a coolant outlet). The principle of a pure electric vehicle type is consistent with that of a hybrid electric vehicle type, the electronic stop valve 7 is disconnected, cooling liquid flows through the motor water pump 13, the four-way electromagnetic valve 12, the high-pressure assembly 11 and the driving motor 10, enters the first multi-way electromagnetic valve 1 from X4, flows out from X2, passes through the temperature sensor 3 and the seat temperature control pipeline 2, flows into the first multi-way electromagnetic valve 1 from X3, flows out from X5, passes through the low-temperature radiator 16 and then flows back to the motor water pump 13 to form circulation.

It can be seen that in the energy-saving heating mode, the heater PTC does not need to be started, the waste heat of the motor cooling loop C is used for providing a heat source for the seat temperature control pipeline 2, and the vehicle heating cost is reduced while the seat temperature is adjusted.

In addition, this embodiment except can heating vehicle seat, can also carry out quick refrigeration to vehicle seat, for example in hot weather, especially the vehicle is through insolate, and the interior temperature of car is higher, only cools down through traditional air conditioner, hardly satisfies driver and passenger's demand in cooling speed and effect.
