A method, apparatus, system, vehicle, and/or computer program provides that one or more components of a vehicle are operated as a function of a predetermined pick-up time of the vehicle at a pick-up position of a parking facility in such a way that the vehicle exhibits one or more predetermined states at the pick-up position at the predetermined pick-up time.

A method for setting a thermal comfort state of at least one user of a vehicle, wherein, at a starting time, at least one actual state variable of the user is detected by at least one device for detecting the at least one state variable and a starting comfort state of the user is determined depending on the at least one actual state variable, wherein a target comfort state is determined, wherein at least one target state variable is determined depending on the target comfort state, wherein at least one vehicle-end device for changing the state variable is controlled so that a deviation in the actual state variable from the target state variable is minimized when the target comfort state deviates from the starting comfort state, wherein the at least one state variable is detected by a device carried by the user for detecting the at least one state variable.

A plug-in air quality detector, a control method, and a control circuit are provided in the field of air quality detection. The plug-in air quality detector comprises a casing, a sensor component, a control circuit and a connector component. The connector component includes a power supply terminal and a data terminal, and is configured to connect the plug-in air quality detector with a user device. As such, the detector may prompt a user of the air quality around the user without being configured with a dedicated power supply and a dedicated display screen, thereby achieving the effects of reducing the size and the weight of the air quality detector and improving the ease of use.

An after-blow control method of a vehicle air conditioner includes: turning on after-blow function applied to the vehicle and turning off the vehicle start, determining, by the controller, whether a condition of the vehicle is satisfied, displaying an after-blower symbol after ignition is turned off if it is determined that the condition of the vehicle is satisfied, determining, by the controller, whether a preset first time has elapsed after the vehicle is turned off, operating the after-blow at a preset intensity for a second preset time and displaying the after-blower symbol if it is determined that the first preset time has elapsed after the vehicle is turned off, and terminating the after-blow function when the second preset time elapses or when the vehicle is turned on.

A method for controlling air conditioning devices in a transportation vehicle wherein, upon the recording of an operator's air conditioning need and a conversion of the need into an air conditioning function for an air conditioning device, the implementability of the air conditioning need is compared with an influencing variable measured by a sensor. In response to the air conditioning need being recognized as implementable, information asserting this fact is issued to the operator. An apparatus for performing the method.

An air-conditioning system comprises a channel system, a system conveying device positioned in the channel system and configured to convey air in the channel system, a sensor device comprising at least one analysis channel and configured to measure a characteristic of air flowing through the at least one analysis channel, and a suction jet pump comprising a motive-fluid inlet, a suction inlet, and a pump outlet. The system conveying device separates a suction area of the channel system arranged upstream of the system conveying device from a pressure area of the channel system arranged downstream from the system conveying device, and the sensor device further comprises a sensor outlet configured to release air from the sensor device. The motive-fluid inlet is fluidically connected to the pressure area via a suction jet branch-off point within the channel system, and the suction inlet is fluidically connected to the sensor outlet.

A mobile environmental sensor system includes a first mobile environmental sensor, a controller, and a network transmitter disposed on a transport unit. The controller is in electronic communication with the first mobile environmental sensor and the network transmitter. The controller includes a processor and a memory. The processor is configured to trigger a measurement from the first mobile environmental sensor. A sensed value is received from the first mobile environmental sensor. The processor compares the sensed value as received from the first mobile environmental sensor to a reference sensed value received by the controller via the network transmitter. The processor calibrates the first mobile environmental sensor based on the comparison of the sensed value as received and the reference sensed value as received. The calibration includes a normalization between the sensed value as received and the reference sensed value as received. The normalization includes a time dependent component.

Systems and methods are provided for estimating a quality of air in proximity to a vehicle. In one embodiment, a method includes: determining a radius of the vehicle; estimating a number of vehicles within the radius of the vehicle; estimating the quality of air based on the number of vehicles; and selectively generating a control signal to an air inlet valve based on the quality of air.

An air purification and microbiological sanitization system for a heating, ventilation, and air conditioning (HVAC) system of railway vehicle includes a casing with a chamber having an inlet opening for inflow of air into the chamber and an outlet opening for outflow of air from the chamber, a plurality of light-emitting diodes (LEDs) for generating germicidal ultraviolet radiation in the chamber, an ionizer device for ionizing air in the chamber, an electronic control unit for controlling the HVAC system, and an air quality sensor for measuring concentration of particulate matter and of carbon dioxide in the air. The electronic control unit controls the radiant power of at least one LED as a function of a measurement signal transmitted by the air quality sensor.
