The heating device 6C of the floor member FLm can send out air in a direction from bottom to top ( Fig. 9A Warm air flows as shown in arrows C1 to C4.

[0129] In addition, if Fig. 9B As shown, the warm air can be sent from the warm air device 6A of the bank 26 to the seated occupant in a manner that crosses the chest area ( Fig. 9A , Fig. 9B As a result, the warm air hits the periphery of the abdomen or chest of the occupant, and the air can be diffused around the occupant H even if there is no shielding object such as a partition wall around the occupant.

[0130] In addition, if Fig. 9A As shown in FIG. 1 , when warm air is accumulated in the upper part of the vehicle interior, the warm air is diffused (arrows D1 and D2 ) along the roof R. In this way, the warm air can be diffused by utilizing the properties of air and the shape of the vehicle.

[0131] In addition, by combining the heating device 6 with the in-vehicle air conditioner 70 installed in the vehicle V, it is possible to form an optimal temperature space suitable for each occupant through energy-saving operation. Fig.10 As shown, when the required temperature T1 is set by the occupant H, the temperature reached by the in-vehicle air conditioner 70 of the vehicle V is set as the base temperature T2, and the deviation temperature α that cannot be reached by the in-vehicle air conditioner 70 is compensated by the heating device 6. For example, when the required temperature T1 is set to 27 degrees, the in-vehicle air conditioner 70 outputs the room temperature to 23 degrees, and the insufficient deviation temperature α, i.e., 4 degrees, is compensated by the heating device 64 degrees. Since the heating device 6 heats only the area around the occupant H, air conditioning can be performed in an energy-saving manner.

[0132] In addition, even if there are multiple passengers who prefer different temperatures, the temperature can be finely adjusted for each passenger nearby. The in-vehicle air conditioner 70 of the vehicle V only needs to output in a manner that reaches the basic temperature T2 (lower than the required temperature T1) as a basis, and high-output operation is not required. Since it is expected that the heater core temperature in the in-vehicle air conditioner 70 can be reduced or the blower output can be reduced, energy-saving operation can be performed.

[0133] In addition to the in-vehicle air conditioner 70 or the heating device 6, the vehicle V is sometimes provided with a door heater, a seat heater, a steering wheel heater provided on the steering wheel, etc. (hereinafter, the heating device 6 and the door heater, the seat heater, the steering wheel heater, etc. are referred to as a nearby air conditioning device). The ECU mounted on the vehicle V can share information such as the indoor temperature or the remaining battery power, the operating status, the number of passengers, etc., so as to operate in a manner that makes the most efficient use of power.

[0134] In addition, ECU is a control device, and is a computer that includes a central processing unit (CPU) as a data calculation / control processing device, a read-only memory (ROM) and a random access memory (RAM) as storage devices, and a communication interface for sending and receiving control commands or data via a vehicle network.

[0135] use Fig.11 An air conditioning process for efficiently performing air conditioning while taking battery power into consideration will be described.

[0136] When the required temperature T1 is input by the passenger, the vehicle interior temperature T0 is compared with the required temperature T1 (step S101). When the vehicle interior temperature T0 is higher than the required temperature T1 (step S101: No), the vehicle interior air conditioner 70 and the nearby air conditioning devices including the heating device 6 are stopped, and the status of the vehicle interior temperature T0 and the required temperature T1 is continuously monitored (step S102).

[0137] When the vehicle interior temperature T0 is lower than the required temperature T1 (step S101: Yes), the interior temperature is heated by the vehicle air conditioner 70 until the interior temperature reaches the base temperature T2 (step S103).

[0138] At this time, it is determined whether the operation in the energy-saving mode is required based on the remaining battery power or the number of passengers (step S104). If it is determined that the operation in the energy-saving mode is not required (step S104: No), all nearby air conditioning devices including the heating device 6 are used to heat the room until the required temperature T1 is reached (step S105). In this way, a comfortable temperature can be reached more quickly.

[0139] When the ECU determines that the operation in the energy-saving mode is necessary (step S104: Yes), only the heater 6 of the seat where the occupant is seated, which can be heated most efficiently, is used for heating (step S106). By using the heater 6 etc. mounted on the vehicle V in this way, efficient air conditioning can be performed in consideration of the remaining battery power etc.

[0140] <Second embodiment>

[0141] The second embodiment of the present invention is described using the accompanying drawings. In the past, as disclosed in Japanese Patent Laid-Open No. 2020-147109, it is known to arrange an air conditioning unit in the front of the vehicle. However, since the air conditioning unit is arranged in the front of the vehicle compartment, the temperature-adjusted air cannot be efficiently delivered to the rear seat.

[0142] In the second embodiment, an object is to reduce heat loss by changing the arrangement location of the air conditioner, thereby improving the efficiency of air conditioning in the vehicle interior.

[0143] Fig.12 1 is a diagram showing the position of the air conditioning unit 71 in the vehicle VA of the second embodiment. Conventionally, the in-vehicle air conditioner 70 is only installed in the front of the vehicle body. Therefore, although the temperature-controlled air can be easily delivered to the front seats FS located near the in-vehicle air conditioner 70, the temperature-controlled air is difficult to deliver to the rear seats RS because of the distance therebetween.

[0144] In view of such a problem, in this embodiment, the air conditioning unit 71 is arranged between the front seat FS and the rear seat RS, so that air conditioning can be performed at a position close to either of them. Since it is located in the center of the room, the heat loss caused by being far away from the air conditioner is reduced, eliminating the negative factor of distance when air conditioning the entire vehicle interior. As a result, the power required for air conditioning the entire vehicle interior can be reduced.

[0145] In conventional gasoline vehicles, the exhaust heat of the engine is used for heating, so no electricity is used to produce warm air. However, in the case of electric vehicles, since there is no engine to heat the air, electricity is needed to produce warm air. Therefore, this causes a reduction in cruising range, especially in winter.

[0146] By disposing the air conditioning unit 71 in the center of the interior as in the present embodiment, it is possible to reduce the electric power required to air-condition the entire vehicle interior, thereby suppressing a reduction in the cruising range.

[0147] In addition, you can Fig.13As shown in the vehicle VB, a duct 72 is provided to connect the air conditioning unit 71 disposed in the center of the interior to each seat. In the past, a heat source was secured separately from the air conditioning by using seat heaters or the like. Since the front seat FS and the rear seat RS are close to the air conditioning unit 71 and are easily accessible, they can be easily connected to the duct and can also supply warm or cold heat.

[0148] In addition, if Figure 14 to Figure 15B As shown, this air conditioning unit 71 and the duct 72 are arranged under the floor. Fig.14 The air conditioning unit 71 is arranged above the battery B as in the vehicle VB1 shown in FIG. Fig.15A and Fig. 15B As in the vehicle VB2 shown in the figure, the air conditioning unit 71 is installed under the floor, and the batteries B are arranged in front, behind, left and right of the air conditioning unit 71. By arranging the air conditioning unit 71 between the batteries B, the height of the floor surface can be suppressed low.

[0149] <Third embodiment>

[0150] The third embodiment of the present invention is described with reference to the accompanying drawings. In the past, as disclosed in Japanese Patent Laid-Open No. 2020-121718, a technology of installing a blower on the upper part of a seat back and the lower part of a seat cushion is known. By using a heating and cooling device using a blower fan, the comfort of the occupants is improved.

[0151] However, the blower installed in the seat back generates wind noise and other noises during operation, so when the load noise accompanying driving is small (the vehicle speed is slow) or when the vehicle is parked, the occupants may feel uncomfortable due to the operating sound. Furthermore, due to the electrification of automobiles in recent years, the sound emitted from the body and the surroundings has decreased, so the operating sound of the air conditioner / seat air conditioning device has been regarded as a further problem.

[0152] In the present embodiment, the output of the warming and cooling device using the blower fan is linked to the vehicle speed to reduce the discomfort caused by the noise.

[0153] Fig.16 The upper part of is a graph showing the relationship between the device output and the vehicle speed when the warm and cool device with the blower device is used. Fig.16 The lower part of is a graph showing the relationship between the device output and the vehicle speed when the warm and cool device without the blower device is used.

[0154] like Fig.16 As shown in the upper part of the figure, when the vehicle is parked or the vehicle speed is slow, the noise is reduced by stopping or reducing the output of the heating and cooling devices such as the air conditioner accompanying the blower device. This suppresses the increase of discomfort. Since the noise of the heating and cooling device is not noticed by the increase of vehicle speed, the comfort can be improved by increasing the output of the heating and cooling device.

[0155] On the other hand, Fig.16 As shown in the lower section of , when the vehicle is stopped or the vehicle speed is slow, the output of devices such as the seat heater that are not accompanied by the blower device is increased, thereby suppressing the reduction in the comfort of the occupant H.

[0156] Furthermore, in the case of a heating and cooling device without noise, when there is enough electric power, a constant high output can be maintained regardless of the vehicle speed.

[0157] In addition, if Fig.17A and Fig. 17B Like the illustrated vehicle seat SA, a seat back 1 may be provided with a seat back side blower fan 81 , and a seat cushion 2 may be provided with a cushion side blower fan 82 .

[0158] In this case, the output of the air conditioner / seat fan can also be controlled according to the noise level in the vehicle interior or the vehicle speed.

[0159] Specifically, if Fig.17A As shown, when the vehicle speed is high, the noise level generated by the vehicle is also high, so the backrest side blower fan 81 provided on the seat back 1 is used.

[0160] The wind from the in-vehicle air conditioner 70 ( Fig.17A The arrow E1) and the wind ( Fig.17A The arrow E2) can improve the comfort of the occupant H. In addition, since the noise level generated by the vehicle is high, the noise of the in-vehicle air conditioner 70 with high noise level or the backrest side blower fan 81 close to the human body will not be a concern, and comfort can be maintained even if their output is set high.

[0161] When the vehicle is at a low speed or stopped, the blower fan 82 disposed at a position away from the ears of the occupant, that is, the cushion side blower fan 82 disposed on the seat cushion 2, is switched to or its output is adjusted. The output of the in-vehicle air conditioner 70 and the backrest side blower fan 81 of the seat back 1 can be reduced.

[0162] When the vehicle is moving slowly or is parked, the noise level is low, so the output of the in-vehicle air conditioner 70 or the backrest side blower fan 81 is set low accordingly, and the output of the air conditioning system away from the human body (the cushion side blower fan 82 of the seat cushion 2 or the door air conditioning device, steering wheel heater, etc.) is increased.

[0163] Furthermore, the blower fan, which is located away from the ears of the occupants, can be used at a constant output regardless of the vehicle speed because the operating sound is not easily transmitted.

[0164] Furthermore, regarding the control of the air conditioning devices such as the in-vehicle air conditioner 70 and the blower fan, not only the vehicle speed but also the in-vehicle noise value may be acquired and control may be performed based on the actual noise value.

[0165] like Fig.18A and Fig.18B In the case where a backrest-side blower fan 81A is provided on the seat back 1 as in the vehicle seat SB shown in the figure, an upper duct 83 for conveying air to the upper part of the seat back 1 and a lower duct 84 for conveying air to the lower part of the seat back 1 may be provided, and the duct used for air supply may be switched by a solenoid valve 85. By using the solenoid valve 85 and switching the air supply position according to the vehicle speed, the discomfort caused by noise can be reduced.

[0166] That is, when the speed is high, the electromagnetic valve 85 is set so that air is supplied from the upper part of the seat back 1 through the upper duct 83 ( Fig.18A In addition, when the vehicle is moving at a low speed or when the vehicle is parked, the electromagnetic valve 85 is used to switch to the lower side duct 84 so that air is supplied from the lower part of the seat back 1 ( Fig.18B Arrow J). When the speed is high, even if the air supply position is close to the ear root, the discomfort is less. On the other hand, when the vehicle speed is slow and the running sound is obvious, the discomfort can be reduced by supplying air from a position far from the ear root.

[0167] <Fourth embodiment>

[0168] The fourth embodiment of the present invention is described using the accompanying drawings. In the past, as described in Japanese Patent Laid-Open No. 2020-147109, there is a known technology for sending temperature-controlled air from the front of the vehicle to perform indoor air conditioning. However, since the entire interior of the vehicle is air-conditioned, the efficiency is poor.

[0169] Therefore, in the present embodiment, only the occupant sitting on the vehicle seat is detected, and efficient air conditioning is performed so that the occupant feels warm or cool locally.

[0170] In this embodiment, the number of passengers is detected by using a seat belt reminder device, a camera in the vehicle, or a human sensor installed on the seat of the vehicle. Then, according to the number of passengers, the power consumption of the heating and cooling devices such as the air conditioner is increased to create a comfortable space in a short time. For example, when only one person is on the vehicle, the output of the heating and cooling device is increased (150%) compared to when four people are on the vehicle, and the required temperature T1 required by the passengers is approached in a shorter time.

[0171] In addition, by determining the position of the occupants, the air outlet of the air conditioner and the direction of the blinds are automatically optimized, thereby efficiently creating a comfortable space. It can maximize the performance in a small space rather than a wide space.

[0172] In addition, efficiency is achieved by operating the air conditioner, heater, etc. only in the area where the occupants are seated and operating only in the areas where they are needed. For example, a thermal imager or a temperature sensor built into the seat is used to detect hot or cold parts of the human body and locally deliver comfortable warm or cold air to the area.

[0173] In this way, since only the required part can be heated efficiently, the discomfort can be eliminated quickly with low power. As a result, the output of the in-vehicle air conditioner, which consumes a lot of power, can be suppressed, achieving power saving for the vehicle.

[0174] In addition, if the seat position or number of passengers H is known, Fig.10 As shown, the temperature may be raised to a basic temperature T2 as a basis by the in-vehicle air conditioner, and the deviation temperature α less than the required temperature T1 required by the occupant H may be compensated by the heating device 6 provided near the occupant H or the like.

[0175] Even if there are multiple users with different temperature preferences sitting in the vehicle, the temperature can be finely adjusted by the temperature adjustment device near the human body. In addition, the vehicle air conditioner 70 only needs to be set to the basic temperature T2 (lower than the required temperature T1 set by the user), so high-output operation is not required. That is, the temperature of the heater core in the vehicle air conditioner 70 can be reduced or the output of the blower can be reduced, which can achieve power saving for the vehicle.

[0176] use Fig.19 The air conditioning process that effectively utilizes the passenger detection information is described. When the passenger H inputs the required temperature T1, the vehicle interior temperature T0 is compared with the required temperature T1 (step S201). When the vehicle interior temperature T0 is higher than the required temperature T1 (step S201: No), the vehicle interior air conditioner 70 and the nearby air conditioning devices including the heating device 6 are stopped, and the status of the vehicle interior temperature T0 and the required temperature T1 is continuously monitored (step S202).

[0177] When the vehicle interior temperature T0 is lower than the required temperature T1 (step S201: Yes), the interior temperature is heated by the vehicle air conditioner 70 until the interior temperature reaches the base temperature T2 (step S203).

[0178] Next, the number of passengers and their seating positions are determined using a seat belt reminder device or an in-vehicle camera (step S204).

[0179] Next, the ECU determines whether operation in the energy-saving mode is required based on information such as the number of passengers or the remaining battery power (step S205). If it is determined that operation in the energy-saving mode is not required (step S205: No), all nearby air conditioning devices including the heating device 6 are used to heat the room until the required temperature T1 is reached (step S206). At this time, the air conditioning device can also be operated in a state where the output is increased compared to the normal state. By using electricity in advance, a comfortable temperature can be reached more quickly.

[0180] When the ECU determines that the operation in the energy-saving mode is necessary (step S205: Yes), only the air conditioning device near the seat where the passenger is seated, such as the heater 6, which can heat the seat most efficiently, is used for heating (step S207). By understanding the number of passengers or the seat positions in this way and using the heater 6 and the like installed in the vehicle V, more efficient air conditioning can be performed.

[0181] The embodiments of the present invention, i.e., the vehicle assembly or the air conditioning method, are described above using the accompanying drawings. In addition, the present invention is not limited to the vehicle assembly mounted on a ground-moving vehicle having wheels such as a car or a railway, and can also be applied to a vehicle assembly mounted on an aircraft or a ship moving outside the ground.
