A sound suppression chamber for a heating, ventilation and air conditioning (HVAC) air handling assembly including a first end, a second end, and a middle portion. The first end includes an aperture that resonates with airflow from the HVAC air handling assembly, the airflow from the HVAC air handling assembly generating an incident sound wave corresponding to a target tone. The second end is closed and opposite the first end. The middle portion extends between the first end and the second end. The first end, the second end, and the middle portion defining a cavity of the sound suppression chamber. The sound suppression chamber generates a reflected wave that is 180 degrees out of phase from the incident sound wave and reflected into the HVAC air handling assembly through the aperture to suppress the target tone.

A vehicle HVAC noise control system includes an air handler, a blower motor, an audio event device and a controller. The air handler is connected to a passenger compartment. The blower motor is operably connected to the air handler to provide a plurality of airflow rates for air flowing into a passenger compartment. The audio event device produces an audio event to the passenger compartment. The controller is operatively connected to the blower motor and the audio event device. The controller controls operation of the blower motor initially at an operating airflow rate and subsequently switches to a noise reducing airflow rate in response to a signal from the audio event device indicating that the audio event device will subsequently produce the audio event.

A method and system capable of variably adjusting an indoor temperature of a vehicle according to characteristics of an object to be protected in the vehicle when a driver has turned off the engine and exited the vehicle are provided. The method includes determining whether a current indoor temperature of the vehicle exceeds a predetermined allowable temperature of an object to be protected and switching an IG terminal of a key box of the vehicle to an ON state. A sustainable time of indoor temperature control of the vehicle is calculated in response to determining that the current indoor temperature of the vehicle exceeds the predetermined allowable temperature of the object to be protected. The indoor temperature of the vehicle is adjusted to be within a predetermined allowable temperature range or indoor air of the vehicle is circulated according to the sustainable time.

Methods and systems for controlling noise generated by a transport climate control system (TCCS) that provides climate control within a climate controlled space of a transport unit are disclosed. The methods and systems include a controller obtaining a noise tolerance, wherein the noise tolerance is a threshold noise level that includes at least a noise level generated by the TCCS; the controller monitoring the noise level generated by the TCCS; the controller comparing the noise tolerance with the noise level generated by the TCCS; upon the controller determining that the noise level generated by the TCCS is greater than the noise tolerance, the controller determining a target operating condition of the TCCS for matching the noise level generated by the TCCS with the noise tolerance; and the controller adjusting the TCCS to the target operating condition to adjust the noise level generated by the TCCS.

A system, method and computer program product for managing the flow of air from a ventilation outlet. The method includes determining a position of a sound detected by at least a first microphone determining a ventilation outlet control data based on the position of the sound controlling the air flow of the at least first ventilation outlet based on the ventilation outlet control data for changing at least one of a direction of the air flow, a spread of the air flow and an intensity of the air flow from at least a first ventilation outlet.

This disclosure relates to a method for operating a ventilation device for providing an air flow. An equipment parameter value of an equipment element of a motor vehicle and a vehicle parameter value of the motor vehicle are detected. Then, the ventilation device is activated subject to the detected equipment parameter value and the detected vehicle parameter value. To activate the ventilation device, a rotational speed of a fan of the ventilation device is set, where the rotational speed is varied subject to the detected equipment parameter value and the detected vehicle parameter value.

The present invention relates to a component part of a climatization system or window system for a recreational vehicle, the component part covers a mounting frame of the climatization system or window system and the component part is selected from an air distribution unit that is configured to distribute air inside the recreational vehicle, a decorative window frame and a shading unit for adjusting the amount of incident light, the component part has one or more attachment portions which, in a mounted state, are accessible by the user from inside the recreational vehicle, wherein each of the one or more attachment portions is either connectable to one particular module or to a plurality of different modules in a mutually exchangeable manner, and wherein the modules include sensors for detecting events or parameter changes inside the recreational vehicle or emitting devices for emitting light or sound.

A method for controlling pieces of equipment of a passenger compartment of a vehicle from a sound signal, each piece of equipment preferably being chosen from the list consisting of a seat, lighting, a dashboard and a ventilation system. The method includes determining a category to which the sound signal supplied belongs, from a list of predefined categories, the categories being representative of the nature of the sound signal, assigning a class to the sound signal from a list of predefined classes associated with the determined category, the classes being a description of the sound produced by the sound signal when the sound signal is read, and the generation, depending on the class assigned to the sound signal, of at least one control signal to at least one piece of equipment in the passenger compartment.

A mobile hearable device for communicating with a vehicle control system is described. The mobile hearable device includes a microphone, and a wireless transceiver configured as one of a near field magnetic induction (NFMI) transceiver and a near field electromagnetic induction (NFEMI) transceiver. The mobile hearable device includes a processor coupled to the transceiver and the microphone. The processor receives a location identifier via the transceiver from a location identification transmitter located in a vehicle, the location identification transmitter is configured as one of a NFMI transmitter and a NFEMI transmitter. If the processor receives a speech signal from a user of the mobile hearable device, it determines whether the speech signal includes an actuator control command and generates a control instruction comprising the actuator control command and the location identifier. The control instruction is transmitted to a vehicle control system and used to control an actuator in a vehicle dependent on the location of the person using the mobile hearable device.
