A cab for a work vehicle includes: walls enclosing a cab environment; a door coupled to one of the walls, one of the walls or the door comprising a vent opening; a heating, ventilation, and air conditioning (HVAC) system coupled to the cab environment and configured to regulate a temperature and a pressure of the cab environment; and a pressure control flap associated with the vent opening and comprising a pressure-relief opening and a magnetic portion that is configured to hold the flap closed when the pressure of the cab environment is below a threshold pressure and allow the pressure to open the flap when the pressure exceeds the threshold pressure.

A method of regulating thermal comfort of an occupant of a vehicle cabin uses a radiant heating tile powered via an energy storage device to generate thermal energy. The method also includes detecting the occupant's position via a position sensor and detecting the occupant's surface temperature and detecting a temperature of the tile via at least one temperature sensor. The method additionally includes determining, via an electronic controller, a rate of change of occupant's surface temperature and a difference between the tile temperature and the occupant's surface temperature relative to a predetermined temperature set-point. The method further includes regulating, via the electronic controller, a power input from the energy storage device to the tile in response to the determined rate of change of the surface temperature and the determined difference between the tile temperature and the occupant's surface temperature to thereby regulate the occupant's surface temperature.

A vehicle air conditioner includes a bypass passage configured to cause a coolant to circulate while bypassing a heater core, a switching device set to switch between a first mode in which the coolant flows through the bypass passage and returns to an internal combustion engine while bypassing the heater core and a second mode in which the coolant flows to the heater core, a coolant-temperature sensor that detects a temperature of the coolant at a part through which the coolant flows in both the first mode and the second mode, and a control unit that controls an operation of a blower based on the coolant-temperature control data. Furthermore, first and second calculating portions are configured to calculate the coolant-temperature control data in the first and second modes, respectively. The first calculating portion calculates the coolant-temperature control data based on the temperature of the coolant detected at start-up of the internal combustion engine, and the second calculating portion sets, as the coolant-temperature control data, a temperature lower than the detected temperature of the coolant.

A vehicular air conditioning device includes a blower, a heating heat exchanger, an auxiliary heater, and a blower controller. The heating heat exchanger heats blown air by exchanging heat between the blown air and the cooling water of the in-vehicle device emitting heat during operation. The blower controller is configured to control the operation of the blower. The blower controller is configured to increase a blowing capacity of the blower with increase of a temperature of the cooling water. The blower controller, during operation of the auxiliary heater, increases the blowing capacity after a waiting time during which the increase of the blowing capacity is prohibited has elapsed since a start-up switch of a vehicle system is turned on. The vehicular air conditioning is capable of implementing a quick warming of the in-vehicle device without impairing the heating feeling of occupant.

A cabin condenser for a heating, ventilation, and air conditioning (HVAC) system for a battery electric vehicle (BEV). The cabin condenser includes a first cabin condenser portion and a second cabin condenser portion. A regulator is configured to control flow of refrigerant from the first cabin condenser portion to the second cabin condenser portion.

A vehicular heat management device includes a first heat source, a second heat source, a heater core, a first heat medium pathway, a second heat medium pathway, a heater core pathway, a switching portion, and a control unit. The first heat source is provided in the first heat medium pathway, and the second heat source is provided in the second heat medium pathway. The heater core is provided in the heater core pathway. The switching portion switches between flowing connection and flowing disconnection. The control unit performs at least one of a switching control and a second heat source control when a temperature of the heat medium of the heater core pathway is at or above a predetermined temperature. In the switching control, the switching portion connects the second heat medium pathway to the heater core pathway. In the second heat source control, the second heat source generates heat.

A wakefulness inducing system is capable of appropriately inducing a wakeful state in a driver even in a self-driving vehicle. A wakefulness inducing system includes a wakefulness degree sensing apparatus that senses the degree of wakefulness of a driver, a touch operation apparatus including a touch operation interface that detects contact by the operating hand of the driver, and a self-driving apparatus that controls self-driving of a vehicle. When the wakefulness degree sensing apparatus senses a reduction in the degree of wakefulness of the driver, the self-driving apparatus provides an instruction to the driver to move the operating hand to the touch operation interface, and the temperature of the operating hand is lowered in the touch operation interface upon detection of contact of the operating hand by the touch operation interface.

The vehicle includes an air conditioner, a temperature sensor configured to measure an indoor temperature of the vehicle, a camera configured to obtain an image data of a passenger, and a bio-signal sensor configured to measure a bio-signal of the passenger. A controller is configured to control, when a predetermined condition is satisfied, the air conditioner to change a type of wind blowing at predetermined time intervals, to obtain emotion information corresponding to the changed type of wind based on at least one of the image data or the bio-signal, and to blow a type of wind for which a degree of positiveness of emotion information is equal to or greater than a threshold level.

A method and system capable of variably adjusting an indoor temperature of a vehicle according to characteristics of an object to be protected in the vehicle when a driver has turned off the engine and exited the vehicle are provided. The method includes determining whether a current indoor temperature of the vehicle exceeds a predetermined allowable temperature of an object to be protected and switching an IG terminal of a key box of the vehicle to an ON state. A sustainable time of indoor temperature control of the vehicle is calculated in response to determining that the current indoor temperature of the vehicle exceeds the predetermined allowable temperature of the object to be protected. The indoor temperature of the vehicle is adjusted to be within a predetermined allowable temperature range or indoor air of the vehicle is circulated according to the sustainable time.
