Definitions
- the invention is in the field of air conditioning systems of an autonomous vehicle.
- the invention relates to the automatic adjustment of an air conditioning system.
- Vehicle means any type of vehicle such as a motor vehicle, moped, motorcycle, warehouse storage robot, etc.
- air conditioning system means any device included in a vehicle capable of modifying the temperature and/or the flow of air inside the vehicle, such as a heater, a cooler, ventilation, a ventilation, an air blower, an air flow manager, a cabin temperature set point manager, a window, an opening, etc.
- the air conditioning system modifies the control of said air conditioning system to isolate outside air from inside air: the air conditioning system is in air recycling mode.
- An object of the present invention is to remedy the aforementioned problem, in particular to limit the transfer of a pathogenic agent by the respiratory route, and to individually protect each occupant of a vehicle.
- a first aspect of the invention relates to a method for controlling an air conditioning system of a vehicle to protect the occupants of said vehicle, said method comprising the steps of:
- the epidemic zone being a geographical zone in which a virus circulates, the detection being determined from information sent by radio frequency, said information comprising an identification of the virus, and from a location of the vehicle in relation to a map comprising the epidemic zones;
- control of the air conditioning system prevents the spread of a pathogen within the vehicle. Each occupant is thus individually protected.
- the new parameterization comprises a modification of the air flows and of the temperature inside said vehicle.
- the air flow and the temperature are automatically adapted according to the type of virus and thus avoids the spread of a virus in an epidemic zone within the vehicle.
- the method further comprises a step of saving an initial setting of the air conditioning system, and steps of: • Detection of a change of situation, the change of situation being characterized by detection of the end of the epidemic zone;
- the change of situation is also characterized by detection of a manual modification of the configuration of the air conditioning system by a user, or by detection of modification of the number of occupants in said vehicle.
- control of the air conditioning system quickly returns to the initial state on request from an occupant of the vehicle or when the number of occupants is changed.
- a detection of a change in the number of occupants is characterized by, for example, the detection of a door opening after said vehicle has stopped, by an unfastened seat belt, ...
- the method further comprises a step of determining and transmitting an alert and/or information signal when a different setting is applied.
- a second aspect of the invention relates to a device comprising a memory associated with at least one processor configured to implement the method according to the first aspect of the invention.
- the invention also relates to a vehicle comprising the device.
- the invention also relates to a computer program comprising instructions adapted for the execution of the steps of the method, according to the first aspect of the invention, when said program is executed by at least one processor.
- FIG. 1 schematically illustrates a device, according to a particular embodiment of the present invention.
- FIG. 2 schematically illustrates a method for controlling an air conditioning system of a vehicle, according to a particular embodiment of the present invention.
- the invention is described below in its non-limiting application to the case of an autonomous motor vehicle traveling on a road or on a traffic lane.
- Other applications such as a robot in a storage warehouse or a motorcycle on a country road are also possible.
- FIG. 1 represents an example of a device 101 included in the vehicle, in a network (“cloud”) or in a server.
- This device 101 can be used as a centralized device in charge of at least certain steps of the method described below with reference to FIG. 2. In one embodiment, it corresponds to an autonomous driving computer.
- the device 101 is included in the vehicle.
- This device 101 can take the form of a box comprising printed circuits, of any type of computer or even of a mobile telephone (“smartphone”).
- the device 101 comprises a random access memory 102 for storing instructions for the implementation by a processor 103 of at least one step of the method as described above.
- the device also comprises a mass memory 104 for storing data intended to be kept after the implementation of the method.
- the device 101 may also include a digital signal processor (DSP) 105.
- This DSP 105 receives data to shape, demodulate and amplify, in a manner known per se, this data.
- the device 101 also comprises an input interface 106 for receiving the data implemented by the method according to the invention and a output 107 for the transmission of data implemented by the method according to the invention.
- FIG. 2 schematically illustrates a method for controlling an air conditioning system of a vehicle, according to a particular embodiment of the present invention.
- Step 201 InZone, is a step for detecting entry of said vehicle into an epidemic zone, the epidemic zone being a geographical zone in which a virus is circulating, the detection being determined from information sent by radio frequency, said information comprising an identification of the virus, and a location of the vehicle relative to a map comprising the epidemic zones.
- Radiofrequency communication is also called wireless communication.
- V2X channels short-range vehicle-to-everything wireless communication channels
- a first type of V2X channel is based on Wi-Fi standards (IEEE 802.11 p) and supports communications between vehicles and between vehicles and infrastructures.
- a second type of V2X channel is based on cellular standards, and in particular on the 5G standard.
- This second type of V2X channel supports communications between vehicles, between vehicles and infrastructures or even between vehicle and cellular network.
- This type of channel existing in parallel with conventional cellular channels, it is notably called “sidelink”, for side link in French, or even “PC5”.
- V2X communications can also be implemented by a user device.
- User device means any electronic device of a user.
- a smartphone for smart phone, a touch pad, a laptop or yet any type of connected object such as a watch, headsets or glasses are examples of user devices.
- radiofrequency communications are also able to transmit information such as an alert indicating an epidemic zone, a type of virus, or pathogenic agent, instructions to be applied, etc.
- An on-board navigation system included in the vehicle, in a device 101 or in a user device, is capable of understanding epidemic zones.
- a combination of these different devices can detect entering or leaving an epidemic zone.
- Step 202 is a step for saving an initial setting of the air conditioning system. Ideally, this step is located before a step for modifying the settings of the air conditioning system, thus making it suitable to return to an initial step, before modifications.
- Step 203 is a step for determining the number of occupants and their location in the vehicle, the determination of the number and location being based on sensors of said vehicle.
- a location of an occupant in the vehicle is the chair occupied by an occupant and/or the geographical position, relative to a reference point of the vehicle, of a part of the body of the occupant such as the head, the nose , the mouth, ...
- the step is divided into two new steps, a first new step of determining the number of occupants, and a second new step of locating the occupants in the vehicle.
- these two new steps are not executed at the same time.
- Step 204, NbOcc>2? is a step of a determination of at least two occupants. If so, proceed to step 205.
- Step 205, DetP1 is a step for determining a new setting of the air conditioning system according to the information sent by radio frequency, the location of the vehicle, the number of occupants and the location of the occupants in the vehicle, the setting being configured to protect one of the occupants of the vehicle from a diffusion of the virus by another of the occupants of the vehicle.
- the new parameterization comprises a modification of the air flows and of the temperature inside said vehicle.
- the determination of the parameter setting is carried out, for example, from information communicated by radio frequency received in step 201, and/or from a correspondence table in the memory 102 of the device 101.
- the method further comprises a step of determining and transmitting an alert and/or information signal when a different setting is applied.
- the occupants are thus informed, by a Human Machine Interface for example, of an operating mode of the air conditioning system
- Step 206, AppP1 is a step for applying the new settings to the air conditioning system, the application of the new settings leading to a different control of the air conditioning system. Thus, the occupants are automatically protected.
- Step 207, Out? is a step for detecting a change of situation, the change of situation being characterized by detection of the end of the epidemic zone.
- the change of situation is also characterized by detection of a manual modification of the configuration of the air conditioning system by a user, or by detection of modification of the number of occupants in said vehicle.
- the end of zone detection is similar to the detection of entry into an epidemic zone described in step 201. or by detection of a user request through an HMI.
- the detection of a possible change in the number of occupants is also a case of stopping the specific control of the air conditioning system.
- Step 208, AppPO is a step for applying the initial settings to the air conditioning system, the control of the air conditioning system is then a function of the initial settings. A change in circumstances was determined in the previous step. It is no longer necessary to change the setting of the air conditioning system. Automatically, the air conditioning system setting returns to the initial state without any action required by a driver or passenger.
- the method further comprises a step of determining and transmitting an alert and/or information signal when a different setting is applied.
- the occupants are thus informed, by a Human Machine Interface for example, of an operating mode of the air conditioning system
- the method according to the invention further comprises a step of activating the first step.
- An activation step is characterized, for example, by the closing of all the doors of the vehicle, by a movement of the vehicle, ...
- Detection of entry into an epidemic zone is also possible using image processing from a camera on board the vehicle, said image processing being able to recognize and interpret road signs on the side of the road.
