A vehicle HVAC system includes: a casing to direct air from outdoors into the interior of a passenger compartment, an air blower blowing the air into the casing, an evaporator disposed in the casing, a heater core disposed downstream of the evaporator, and front and rear seat side temperature doors disposed between the evaporator and the heater core. A method for controlling the HVAC system includes: determining, by a controller, whether a required temperature for cooling rear seats is set to be lower than a required temperature for cooling front seats after an outdoor condition of a vehicle meets a reference high temperature condition; and lowering, by the controller, a target temperature of the evaporator based on the set required temperature for cooling the rear seats when the required temperature for cooling the rear seats is set to be lower than the required temperature for cooling the front seats.

A vehicle air handling system includes a user input interface, air duct housing, first and second panel duct doors, at least one air blower, and a first panel actuation assembly. The air duct housing has an air inlet, and first and second panel ducts. The first and second panel duct doors are disposed to selectively open and close the first and second panel ducts, respectively. Air is drawn into the air duct housing via the air inlet and conveyed toward the panel ducts. The first panel actuation assembly is operatively coupled to the first and second panel duct doors to simultaneously control positions in response to operation of the user input interface between a plurality of settings. The positions of the first and second panel duct doors include at least one setting in which different airflow volumes are passed by the first and second panel duct doors.

An air outlet, in particular for heaters or air conditioning units for recreational vehicles like campers or caravans, having a main housing, a flap suitable to seal the air flow channel in the main housing and a coupling mechanism. The main housing forms an air flow channel and the coupling mechanism couples the flap to the main housing in a movable manner such that the flap can be moved with respect to the main housing between a closed state, in which the flap seals the air flow channel, and an opened state, in which the flap does not seal the air flow channel. The coupling mechanism is configured such that the flap conducts a rotating and sliding movement with respect to the main housing when being moved between the closed state and the opened state.

A method of maintaining a position of an airflow-direction control element 16 of a HVAC system, comprising the steps of, a] determining a position of at least one movable member of an airflow-direction control mechanism of the HVAC system; and b] calculating whether the movable member is at a target position associated with a required position of the airflow-direction control element, and if not, activating an airflow-direction-controller actuator of the HVAC system to effect a change in the position of the movable member thereby bringing the airflow-direction control element to or towards the said required position. A HVAC system suitable for implementing such a method is also provided and capable of improving the overall efficiency of operation.

A drive device with an abnormality detection mechanism may include a drive source; a drive member to which power of the drive source is transmitted; a driven member operably coupled to the drive member; and a detector structured to output a signal in response to the driven member being turned in the second direction around the second axial line. The driven member may be structured such that, in response to the drive member being turned in a first direction around a first axial line, the driven member is turned in a first direction around a second axial line; and, in response to transmission of the power from the drive member being disconnected, the driven member is turned in a second direction around the second axial line.

A rotary apparatus includes a motor, a plurality of gears, and a sensor configured to detect a rotation angle of one of the plurality of gears. The sensor includes a first connection terminal electrically connecting to the outside, and a base portion. The first connection terminal is disposed at the base portion. A second connection terminal is disposed at the base portion.

The present disclosure relates to a gear motor formed of a housing. An electric motor includes a stator assembly and a rotor driving a reduction gear train having a plurality of intermediate stages each formed by a shaft coupled to a toothed wheel and to a toothed gear. Also, an output stage is formed by a shaft coupled to a wheel and a coupling component, the shafts of the rotor, of the intermediate stages and of the output wheel being parallel. The gear motor further includes a printed circuit transversely positioned above the stator assembly, wherein the wheel of the output stage is positioned above part of the stator assembly, the shafts of the intermediate stages are located in the zone of the housing located on the opposite side, relative to a transverse vertical plane, of the zone including the shaft of the rotor and the shaft of the output wheel.

A vehicle HVAC system includes: a casing to direct air from outdoors into the interior of a passenger compartment, an air blower blowing the air into the casing, an evaporator disposed in the casing, a heater core disposed downstream of the evaporator, and front and rear seat side temperature doors disposed between the evaporator and the heater core. A method for controlling the HVAC system includes: determining, by a controller, whether a required temperature for cooling rear seats is set to be lower than a required temperature for cooling front seats after an outdoor condition of a vehicle meets a reference high temperature condition; and lowering, by the controller, a target temperature of the evaporator based on the set required temperature for cooling the rear seats when the required temperature for cooling the rear seats is set to be lower than the required temperature for cooling the front seats.

A rotary apparatus includes a motor, a plurality of gears including an output gear, and a housing accommodating the plurality of gears and the motor. The housing includes a first surface portion, a second surface portion facing the first surface portion and spaced apart from the first surface portion, and a sidewall portion provided at an outer peripheral portion of the first surface portion and the second surface portion and supporting the first surface portion and the second surface portion. One of the first surface portion and the second surface portion includes a vibration damping part opposing the output gear.

An air handling system of a vehicle comprises a housing defining an inlet section. The inlet section includes a recirculation inlet in fluid communication with a passenger compartment of the vehicle and a fresh air inlet in fluid communication with an ambient environment. An air distribution door is disposed in the inlet section for controlling a distribution of air entering the inlet section through the recirculation inlet and the fresh air inlet. A baffle door is disposed in the inlet section for selectively reducing a flow area through the fresh air inlet to accommodate a ram air pressure induced by motion of the vehicle relative to fresh air of the ambient environment.
