A vehicle scent dispensing device may comprise a scent cartridge configured to contain a scenting agent, a controller configured to determine a scent diffusion level of the scenting agent, a valve, and a fan. The controller may be configured operate the valve and control the fan to regulate an airflow pathway to the scenting agent and to draw air through the airflow pathway and over the scenting agent based on the scent diffusion level.

Embodiments generally relate to a method, an apparatus, and a machine-readable medium for scent dispensing. In particular, embodiments relate to a method dispensing at least one scent medium into an atmosphere. The method comprising increasing a concentration of the at least one scent medium in the atmosphere during a first time period; decreasing a concentration of the at least one scent medium in the atmosphere during a second time period; and increasing a concentration of the at least one scent medium or another scent medium in the atmosphere during a third time period.

In a driving switching preparing section of a road wherein autonomous driving performed by an autonomous driving ECU or autonomous driving controller is switched to manual driving performed by a driver, an air conditioner ECU or an air conditioner controller is configured to prohibit air conditioner power cutting control.

A vehicle system includes: a blower configured to draw air from within a passenger cabin of a vehicle through an inlet; a binding agent source configured to flow a binding agent into the air; and a sensor disposed downstream of the binding agent source in the direction of airflow, the sensor configured to determine an amount of smoke in the air from within the passenger cabin based on a measured characteristic of particulate at the sensor and a predetermined characteristic of the binding agent.

To realize a device and method that outputs scents according to an advertisement. A scent output control unit that executes scent output control and a scent output unit that executes a scent output under control of the scent output control unit are included, and the scent output control unit selects a scent to be output on the basis of an advertisement and outputs the selected scent via the scent output unit. The scent output control unit selects a scent to be output on the basis of an advertisement detected from an image captured by a vehicle exterior camera that captures the outside of the vehicle or an advertisement output to the information output terminal, and outputs the selected scent via the scent output unit. Furthermore, an occupant profile is analyzed on the basis of an image of an occupant, and a scent corresponding to the occupant is output.

The invention relates to the field of fragrance technologies, and specifically provides a vehicle and a control method of a fragrance of the vehicle, a fragrance unit, a vehicle, a computer storage medium, and a control apparatus. The fragrance system includes: a fragrance module including a housing and at least one fragrance chamber disposed in the housing, where an NFC antenna is configured above each fragrance chamber; and a fragrance unit, which is configured in the fragrance chamber in a removable manner and able to send forth a fragrance corresponding to the fragrance unit into target space when the fragrance module is enabled, where the fragrance unit is provided with an NFC tag that is loaded with identity information of the fragrance unit, where the NFC tag is disposed in the fragrance unit in a built-in manner. In this way, a fragrance unit can be reliably recognized based on NFC.

An air scenting device for introducing at least one fragrance into a vehicle interior of a motor vehicle is disclosed. The air scenting device includes at least one fragrance cartridge arranged in a housing interior of a housing. An adjustment mechanism is provided for adjusting at least one flap closure between an open position, where the flap closure releases at least one of an inlet opening and an outlet opening of a cartridge housing, and a closed position, where the flap closure closes the at least one of the inlet opening and the outlet opening. A fragrance inlet is disposed on the housing for introducing air to be admixed with fragrance, and a fragrance outlet is disposed on the housing for discharging the air admixed with fragrance.

A vehicle includes a lock device, a gas generator, an air conditioner, and an ECU. The gas generator generates, in a vehicle compartment of the vehicle, a gas having a sterilizing effect or a deodorizing effect. The air conditioner ventilates the vehicle compartment. The ECU starts operation of the gas generator when a request for operation of the gas generator is made and the door is in the locked state, starts ventilation by the air conditioner after the gas generator is stopped, and keeps the door in the locked state when a request to switch from the locked state to the unlocked state is made during a period from start of the operation of the gas generator to end of the ventilation by the air conditioner.

A vehicle seat that includes: at least one support element defining a cavity, an air pump, and at least one olfactory diffuser arranged in the cavity and fluidly connected to the air pump, the olfactory diffuser having an outer casing defining an inner volume, the outer casing defining an air inlet and an air outlet, the olfactory diffuser further having at least one olfactory substance carrier arranged in the inner volume defined by the outer casing. The air pump causes the circulation of a flow of air through the inner volume from the air inlet to the air outlet toward the outside of the cavity.
