A cabin air state sensing system for a vehicle may include a divergence structure facilitating measurement of cabin air temperature and dust concentration in a cabin through suction of air using an air suction device and an operation method thereof.

A sensor unit for vehicles for detecting at least the moisture and/or the temperature on the inside of a vehicle window by a sensor is disclosed. The sensor unit is mounted adjacent to the inside of the vehicle window, the sensor unit comprises a housing within which it is partially enclosed, the housing has at least one opening in the direction of the vehicle window through which the sensor unit is pressed against the vehicle window. The sensor unit has a printed circuit board (PCB) that is pressed against the inside of the vehicle window when the sensor unit is in the mounted state, and is arranged between the sensor and the vehicle window. The PCB is a rigid-flexible PCB comprising a bend at least in a partial region, the bend of the rigid-flexible PCB being set up in such a way as to generate an elastic restoring force, which presses the rigid-flexible PCB against the vehicle window. The rigid-flexible PCB has at least one recess for receiving a fixing means and these together are designed to hold the rigid-flexible PCB in a specific shape.

A thermal management system for a passenger cabin of a hybrid vehicle includes a refrigerant loop in fluid communication with a compressor, a condenser, and a chiller. A main cabin evaporator is in fluid communication with the refrigerant loop. A first valve is configured to regulate refrigerant flow through the main cabin evaporator. A temperature sensor disposed at the main cabin evaporator is configured to output a signal indicative of a main cabin evaporator temperature. An auxiliary evaporator is in fluid communication with the refrigerant loop. A second valve is configured to regulate refrigerant flow through the auxiliary evaporator. A controller is programmed to, in response to the main cabin evaporator temperature being less than a threshold while the main cabin evaporator is operated with the second valve closed, open the second valve to cycle refrigerant through the auxiliary evaporator to increase the main cabin evaporator temperature.

A vehicle interior ventilation system has air outlet slots in a dashboard or a different panel of the vehicle. A display is provided in the dashboard or the different panel, on which display the air flow direction of an airflow resulting from the airflows coming from the air outlet slots can be displayed.

Provided is a control unit and a system for monitoring in real-time and/or controlling the air quality of a vehicle cabin. Upon receiving input data from various sensors in the cabin of the vehicle, the control unit processes the data and outputs a unified processed/calculated data of all the sensed data from sensors in the cabin that is indicative of the general air quality in the cabin. In addition, the control unit may output instructions of operations that need to be carried out for optimal circulation of the air that results in improvement of the air quality within the cabin. These instructions of operations may be also affected from data that is received by the control unit that is indicative of the air quality in the surrounding of the vehicle.

The invention relates to a sensor module (1) for measuring at least one measurand, comprising: a housing (2) having a flow duct (23) with an air inlet (21) and an air outlet (22), the housing (2) enclosing an interior (20) of the housing (2); a circuit board (4) arranged in the interior (20); at least one sensor (3) which is arranged on the circuit board (4) and is designed to measure at least one measurand of an air flow (L) conducted past the sensor (3); a terminal (5) arranged on the circuit board (4) for making electrical contact with the sensor module (1); and a fan (6), which has a motor (60) and a rotor (61) which can be rotated about an axis of rotation (z) by means of the motor (60), the motor (60) being electrically conductively connected to the circuit board (4), and the fan (6) being designed to generate an air flow (L) in the flow duct (23) between the air inlet (21) and the air outlet (22) such that the air flow (L) flows past the sensor (3) and, in the region of the air inlet (21), flows in a flow direction (x) which runs at an angle (V) in the range of 45° to 90° to the axis of rotation (z).

An electronic sensor assembly for a recreational vehicle may include a wired electronic sensor and a sensor cover supporting the wired electronic sensor on an interior wall. The sensor cover may include a cover sidewall, a cover faceplate, and a sensor clip arm. The cover sidewall may be in selective engagement with the interior wall. The cover faceplate may extend from the cover sidewall. The cover faceplate may have an outer surface direct outward from the interior wall and an inner surface directed inward toward the interior wall. The sensor clip arm may extend inward from the inner surface. The sensor clip arm may hold the wired electronic sensor within an interior volume defined by the cover sidewall and the cover faceplate.

A recreational vehicle air conditioning system supports multiple recreational vehicle air conditioning units having closed air conditioning circuits and a controller that is electronically coupled to each of the recreational vehicle air conditioning units to control each of the closed air conditioning circuits to regulate an overall power consumption of the multiple recreational vehicle air conditioning units. A recreational vehicle air conditioning system may also support multiple recreational vehicle air conditioning units where a refrigerant line set is coupled between the recreational vehicle air conditioning units such that a compressor in one of the recreational vehicle air conditioning units is capable of supplying refrigerant to the evaporators of the multiple recreational vehicle air conditioning units, and such that valves coupled in series with each of the evaporators may be regulated to control cooling by each recreational vehicle air conditioning unit.

A system and method for controlling and diagnosing an automotive climate control or environmental system with an electronic or mobile device is disclosed. The system provides for wireless control between the system controllers and an electronic device, such as an electronic device or computer, with instructions executed on a processor to display on the electronic device or the computer-human interface display device with a user interface region or a graphical user interface. Using wireless technology features of an electronic device, the automotive climate control system is wirelessly controlled from the electronic device containing software connected with the climate control system software and firmware mounted within the vehicle that rotates servo motors, and operates fan speed and compressor activity. The user interface regions may be used to create preset, predetermined desired positions of system mode, temperature, fan speed, and the display color and appearance of the user interface region.
