Sun load on a cabin of a vehicle is determined without a sun load sensor by affixing a relative humidity/temperature sensor to an inside of a windshield of the vehicle. The relative humidity/temperature sensor includes a relative humidity sensor that senses relative humidity of air at the relative humidity sensor, a temperature sensor that senses temperature of the air at the relative humidity sensor and a glass temperature sensor that senses temperature of glass of the windshield. A controller determines the sun load based on readings from the relative humidity/temperature sensor of relative humidity of the air at the relative humidity sensor, temperature of the air at the relative humidity sensor and temperature of the glass of the windshield.

A sensor apparatus for examining a sample gas volume, particularly for capturing the particulate matter content of a sample gas volume, includes at least one measuring chamber to accommodate the sample gas that is to be analysed, and at least one sample gas feed allocated to the measuring chamber and with at least one sample gas discharge allocated to the measuring chamber, in which it is provided as essential for the invention that at least one cleaning gas feed is allocated to the measuring chamber, that the cleaning gas feed is connected to the measuring chamber via at least one cleaning gas inlet, that a condensation area is allocated to the cleaning gas feed, and that the condensation area is arranged in front of the cleaning gas inlet of the cleaning gas feed into the measuring chamber.

The present invention relates to a fluid line system (10) for guiding fluid, in particular for a motor vehicle. The fluid line system (10) comprises a sensor device (20) for capturing sensor parameters and a housing (30), which has two or more housing parts (40, 60). Each housing part (40, 60) has a mounting surface area (50, 70) for arranging a further housing part (40, 60). The housing (30) further has a groove arrangement (80), which comprises at least one groove recess (90), which is arranged on a mounting surface area (50, 70), wherein a groove recess (90) has a groove opening (95), which opens out to the respective mounting surface area (50, 70). In any case, the groove opening (95) is closed by in a fluid-tight manner means of the mounting surface area (50, 70) of at least one further housing part (40, 60). It is attained thereby that a fluid duct (99), through which fluid can flow and through which fluid can be applied to the sensor device (20), is limited between the respective groove recess (90) and the respective mounting surface area (50, 70).

A method for controlling a heating, ventilation, and air-conditioning (HVAC) system of an autonomous vehicle includes determining a vehicle operating status and operating the HVAC system according to the determined vehicle operating status. A control module comprising a sensor array and at least one controller operatively coupled to the sensor array and to the HVAC system controls operation of the HVAC system according to the determined vehicle operating status. The vehicle operating status is selected from one of vehicle occupied-in use, vehicle unoccupied-use requested, and vehicle unoccupied-standby. The HVAC system is operated at an operating setting providing a reduced energy consumption in a vehicle whose operating status is vehicle unoccupied-standby. The reduced energy consumption operating setting is determined according to a constant offset value or according to a variable offset value determined by inputs provided by the sensor array.

A dual-passage air quality detection device includes a housing, an air quality detection module, a fan, and a main control PCB (printed circuit board). The air quality detection module includes two passages, two laser modules and two photodiodes therein. The fan includes two fans. One of the passages is communicated with the inside of the vehicle, and the other of the passages is communicated with the outside of the vehicle to form two independent air passages for detection. Each of the passages corresponds to one fan for independent sampling, not affecting each other.

An air conditioning control system includes: an air conditioner that blows wind at a set temperature into an interior of a cabin of a vehicle; an information acquisition unit that acquires distance measurement information inside the cabin from a front reference position in the cabin; a position acquisition unit that acquires a three-dimensional position of a head of a passenger inside the cabin based on the distance measurement information; and a control unit that controls an air blowing direction of the air conditioner based on at least the position acquired by the position acquisition unit.

Embodiments are provided for a system configured to provide pre-trip sequence and diagnostics for refrigerant leak sensor. The system includes a sensor, a fan, and a controller. The controller is further configured to validate an operation of the sensor, operate the fan based at least in part on validating the operation of the sensor, and responsive to operating the fan, determine if a leak is present using the sensor. The controller is also configured to perform a refrigeration test, determine if a leak is present using the sensor, and provide an alarm based at least in part on determining the leak is present. Embodiments are also provided for a method for performing a pre-trip sequence and diagnostics for a leak sensor.

Methods and systems are provided for personalized controlling of an air temperature in a vehicle. A computer implemented method for personalized controlling of an air temperature in a vehicle comprises determining, by a processor, a current temperature condition in the vehicle, wherein the current temperature condition in the vehicle is determined based on at least a temperature value that is representative for a current thermal environment in a compartment of the vehicle. The processor further determines a basal metabolic rate that is associated with a person located in the compartment of the vehicle and controlling, by the processor, a desired air temperature in the vehicle, wherein the desired air temperature is controlled based on the determined current temperature condition in the vehicle and the determined basal metabolic rate.
