A computer includes a processor and a memory, the memory storing instructions executable by the processor to receive first input to sanitize a vehicle passenger cabin via a passenger cabin heater, output one or more candidate initiation times at which to begin actuation of the heater, and, then, actuate the heater to a temperature above a specified sanitization threshold according to the initiation time identified in a second input.

The present disclosure provides a photosensor structure including a left photosensor located at the left side of a front windshield of a vehicle viewed from the outside of the vehicle, and a right photosensor located symmetrically to the left photosensor. For example, the left photosensor includes two light reception windows located in a width direction of the vehicle to set a lateral incidence angle having a maximum incidence amount in a left-and-right direction of a light source, a dummy portion located on at least one of the two light reception windows between the two light reception windows to set an incidence altitude having a maximum incidence amount in an upward-and-downward direction of the light source, and light reception units located on lower ends of the light reception windows to measure the amount of light received from the light source through the light reception windows.

A vehicle heating, ventilation, and air conditioning (HVAC) system including a cabin air filter, a sensor for providing a sensor reading, and a controller for determining a feedback signal from the sensor reading, wherein the controller determines a cabin air filter expected blockage level from the feedback signal. The feedback signal relates to a usage modifier of the cabin air filter, wherein the controller at east partially adjusts the estimated usage the cabin air filter from the usage modifier.

The present disclosure relates to an interior temperature sensor for a vehicle. The sensor includes a sensor casing disposed to expose a sensing surface to a space that is the subject of temperature measurement, a substrate extending in a direction from an inside of the sensing surface toward an outside while at least a part of the substrate bisects an inside of the sensor casing into upper and lower sections, an upper temperature sensing element provided on an upper surface of the substrate at a position inside the sensor casing, a lower temperature sensing element provided on a lower surface of the substrate at a position inside the sensor casing, and a compensation temperature sensing element provided on the substrate to be placed outside the sensor casing. Furthermore, a microcomputer determines an interior temperature of the vehicle based on the measured values.

Disclosed is a vehicle air conditioning device including a heat pump cycle configured to compress and expand a refrigerant; a heater core; a high pressure side pressure sensor configured to detect a pressure on the high pressure side of the heat pump cycle; and a heater core inlet water temperature sensor configured to detect a temperature of cooling water at an inlet of the heater core as a heater core inlet water temperature. The heat pump cycle includes a compressor; a condenser; a water refrigerant heat exchanger and an evaporator; and a heating expansion valve and a cooling expansion valve. An estimated outside air temperature is calculated based on the high pressure side pressure detected by the high pressure side pressure sensor and the heater core inlet water temperature detected by the heater core inlet water temperature sensor.

An air conditioning control device acquires environmental measurement information, acquires an action schedule of a user of a host vehicle on the basis of past or future schedule table information of the user, and estimates a boarding time at which the user gets on the host vehicle, a destination, and a route based on the action schedule. The control device then derives an instruction value pattern that includes a first instruction value for the air conditioning device at the boarding time, a second instruction value for the air conditioning device in a travel route toward the destination, and a third instruction value for the air conditioning device in a case that the user gets on after getting off the vehicle, based on the environmental measurement information. An air conditioning controller controls an air conditioning device of the host vehicle based on the instruction value pattern.

A HVAC thermal conditioning system provides a macroclimate environment. An auxiliary thermal conditioning system has multiple microclimate devices. The microclimate devices are configured to be arranged within an interior space that provides the macroclimate environment to an occupant. The microclimate devices provide a microclimate environment to the occupant different than the macroclimate environment. The microclimate devices are in close proximity to a region of the occupant. A controller calculates an occupant personal comfort based upon a thermal energy experienced by the occupant from thermal radiation sources, thermal convection sources, and thermal conduction sources, and to automatically command the microclimate devices in response to the calculated occupant personal comfort based upon occupant characteristics to achieve a desired occupant personal comfort. The automatic command is to adjust and apportion the thermal conduction sources and/or thermal radiation sources experienced by the occupant to achieve the desired occupant personal comfort.

A vehicle ventilating/cooling system may include at least one sun-load sensor arranged within the vehicle, and a controller configured to receive a sun-load signal indicating a sun-load level from the sensor and programmed to instruct at least one cooling component to conduct a purge of vehicle cabin air in response to the sun-load level exceeding a sun-load threshold.

A method and apparatus to control an air conditioning system in a passenger compartment of a road vehicle comprising the steps of detecting a body temperature of at least a part of the body of one or more occupants of the passenger compartment and transmitting the detected body temperature to the air conditioning system, which controls a plurality of ventilation devices arranged inside the passenger compartment. The method comprises the further steps of identifying the number and the position of the one or more occupants seated in the passenger compartment; determining an optimized tuning at least based on the body temperature detected by the sensor member and controlling the ventilation devices as a function of the optimized tuning.
