Abstract: A device temperature adjusting apparatus in which working fluid circulates is mounted on a vehicle and controls a temperature of a target device. The device temperature adjusting apparatus includes a heat absorbing portion that evaporates the working fluid by causing the working fluid to absorb heat from the target device, and a heat releasing portion condenses the working fluid by causing heat release from the working fluid. The device temperature adjusting apparatus includes a forward path portion that defines a forward flow passage and a return path portion. The heat releasing portion is disposed in an inside air circulation path through which inside air circulates while vehicle interior air conditioning is performed by an air conditioning unit that blows out temperature-controlled air to an interior of the vehicle.

Abstract: A device temperature regulator is provided with a gas passage part that guides a gaseous working fluid evaporated in a device heat exchanger to a condenser, and a liquid passage part that guides a liquid working fluid condensed in the condenser to the device heat exchanger. The device temperature regulator is provided with a supply amount regulator that increases or decreases a supply amount of the liquid working fluid supplied to the device heat exchanger. The supply amount regulator decreases the supply amount of the liquid working fluid to the device heat exchanger such that a liquid surface is formed in a state where the gaseous working fluid is positioned at a lower side lower than a heat exchanging portion exchanging heat with a temperature regulation target device in the device heat exchanger, when a condition for keeping the temperature regulation target device at a temperature is satisfied.

Abstract: A thermal management system for a vehicle includes a switching power supply device, an electronic member configured to output an electrical power adjusted by the switching power supply device, and a control device configured to control operation of the switching power supply device. When the control device receives a heating request from at least one of devices that include a drive device used for driving the vehicle and an air conditioning device used for performing an air conditioning in a vehicle compartment, the control device causes the switching power supply device to be operated in a heat increasing operation in which heat generated from the electronic member is increased more than that in a general operation state, and supplies the generated heat to the at least one of the drive device and the air conditioning device.

Abstract: A sleepiness level detection device detects a heartbeat signal when a time equal to or longer than T1 and equal to or shorter than T2 has elapsed since the start of driving. The heartbeat signal is subjected to FFT processing to obtain a spectrum signal. By use of a peak frequency of the spectrum signal, a driver conscious-state peak frequency is estimated. A consciousness level index band ? is set with respect to the conscious-state peak frequency. A sleepiness level index band ? is set with respect to a frequency, which is calculated by multiplying the conscious-state peak frequency by a predetermined ratio (65 to 90%). A sleepiness level evaluation parameter Sp (=?p/(?p+?p)) for indicating the sleepiness level of the driver is calculated with the use of the strength ?p and ?p of spectrum signals.

Abstract: A vehicle air conditioning system includes a space air conditioning unit for blowing conditioned air into a passenger compartment, a seat air conditioning unit for blowing air into a vehicle seat, and a control unit for controlling the space air conditioning unit and the seat air conditioning unit. The control unit includes space controlling means for controlling the space air conditioning unit in accordance with a space control value calculated based on a space target air temperature, and seat controlling means for controlling the seat air conditioning unit in accordance with a seat control value calculated based on the space target air temperature. Further, the seat controlling means includes a first seat air conditioning means which determines the seat control value in a steady air conditioning state of the passenger compartment, and a second seat air-conditioning means which determines the seat control value in a transition air-conditioning state of the passenger compartment.

Abstract: An air conditioning system for a vehicle exhibits a room air conditioner unit for air conditioning a passenger compartment, a seat air conditioner unit for adjusting a temperature of a seat, a temperature sensor for detecting a temperature at a front location of a passenger seated on the seat and the temperature of the seat, and a control unit for controlling operation of the room air conditioner unit and the seat air conditioner unit so that a difference between the temperature at the front of the passenger and the temperature of the seat falls within a certain value range. As a result, a difference in heat sensation between the front and the back of the passenger is reduced, and hence the comfortableness of the passenger compartment can be improved.

Abstract: A sitting position of a vehicle occupant in the longitudinal direction of a vehicle is detected, an outlet close to the sitting position of the occupant from plural outlets and is selected based on the detected sitting position, and air is blown out from the selected outlet toward the occupant's sitting position. Thus, since an outlet close to the occupant's sitting position is selected, it becomes easier for air to reach the vehicle occupant to sufficiently cool or warm the occupant with a small amount of blown out air.

Abstract: In a vehicle air conditioner, each of cool air outlets is provided at an upper side of each seat at second and third seat lines from a most front seat so that cool air from an air conditioning unit is blown from the cool air outlets toward upper sides of the seats, respectively, and each of warm air outlets is provided at a lower side of each seat at the second and third seat lines so that warm air from the air conditioning unit is blown from the warm air outlets toward lower sides of the seats, respectively. In addition, each of suction ports is provided for each corresponding seat at the second and third seat lines so that air inside a passenger compartment is sucked from the suction ports to be returned to the air conditioning unit.

Abstract: A seat air duct includes a floor duct fixed to the floor surface of vehicle cabin and flexible ducts. The upper wall of the floor duct is partially formed by flexible slide walls. The flexible slide walls are formed in an accordion and stretch and contract to follow a front-back stroke of a front seat. The flexible ducts stretch and contract to follow a vertical stroke of the front seat. In this way, since the flexible slide walls and the flexible ducts are independently provided, the seat air-conditioning unit effectively follows the front-back and vertical strokes of the passenger seat, thereby improving a seat air-conditioning performance.
