Description

The invention relates to a method for operating an interior of a motor vehicle and to an interior of a motor vehicle. Several seats are arranged in the interior. The invention also relates to a computer program product.

Motor vehicles, such as passenger cars, are used at least in part to transport people. These people are usually located in an interior of the motor vehicle in which one or more seats are arranged. The people can be adults who can essentially operate the motor vehicle independently. However, it is also possible that there are children in the interior who, due to their reduced size, cannot fully operate the motor vehicle. For example, due to their comparatively small size, it is not possible for them to open the side window assigned to the respective seat, or the operation of the side window is blocked by a driver or other user of the motor vehicle for safety reasons.

Children usually sit in a rear seat, so that they are not in the direct field of vision of the driver of the vehicle. This means that the driver of the vehicle cannot continuously assess the child's situation. Air conditioning is usually provided to regulate the temperature in the interior. This is usually adjusted by the driver of the vehicle. However, it is possible that the driver is in the shadow of parts of the vehicle due to the position of the sun, so that he or she finds the current temperature pleasant. However, if the child is in direct sunlight, the perceived temperature is higher for him or her. There is also a risk due to the radiation.

The invention is based on the object of specifying a particularly suitable method for operating an interior of a motor vehicle as well as a particularly suitable interior of a motor vehicle and a particularly suitable computer program product, wherein safety and/or comfort is advantageously increased.

With regard to the method, this object is achieved according to the invention by the features of claim 1, with regard to the interior by the features of claim 6 and with regard to the computer program product by the features of claim 8. Advantageous further developments and embodiments are the subject of the respective subclaims.

The method serves to operate an interior of a motor vehicle, which is also referred to as the passenger compartment. The motor vehicle is in particular land-based and preferably designed with multiple lanes. In this case, it is suitably possible to position the motor vehicle essentially freely, in particular on a corresponding roadway. For this purpose, the motor vehicle has, for example, corresponding wheels. In summary, it is preferably possible to position the motor vehicle essentially independently of other conditions on land. In other words, the motor vehicle is suitably not rail-guided. Preferably, the motor vehicle is a passenger car (car) or a commercial vehicle, such as a truck (lorry) or bus.

Several seats are arranged in the interior. For example, the seats are each a component of the interior or at least of the motor vehicle. The seats are, for example, individual seats or some or all of the seats are combined to form one or more benches. If the motor vehicle is a passenger car, the number of seats is in particular between two seats and seven seats. Each of the seats is suitable, in particular intended and set up, for a person to sit on it. For example, one or more of the seats are adjustable so that the comfort of the person sitting on the seat is increased.

The motor vehicle, preferably the interior, further comprises a sensor device. The sensor device makes it possible to determine several environmental parameters. For example, there is only one type of environmental parameter, the course of which is determined over time, and/or different environmental parameters are determined, which in particular describe different physical conditions. For example, the respective environmental parameter is measured directly and the respective environmental parameter is determined based on the measurement data. Alternatively, the environmental parameter is derived based on measurement data that is created using the sensor device, for example, or that is queried by a sensor using the sensor device, for example. The sensor and the sensor device are connected to one another in terms of signal technology, for example directly or via a possible bus system. In this case, the sensor is not a component of the sensor device, for example, but in an alternative it is a component of the interior or at least of the motor vehicle. Alternatively, the sensor is separate from the motor vehicle.

The environmental parameters relate to the interior, so that they prevail there. In other words, the environmental parameters describe in particular a condition, situation or property of the interior or at least a property that influences the, preferably current, situation in the interior. In this case, the environmental parameter is, for example, not directly controllable and/or in particular has an influence on people in the interior.

The method provides that the environmental parameters for the interior are determined using the sensor device. In a further step, a quality of life value assigned to the respective seat is determined based on the environmental parameters. In other words, the quality of life value is determined in particular for each or at least several of the seats or at least assigned to the respective seat. This means that the quality of life values assigned to different seats can differ at the same time.

The quality of life describes, for example, a risk and/or comfort of the person sitting in the seat or is particularly dependent on this. The situation of the people sitting in the respective seat can therefore be derived from the quality of life value. As a result, if there is a risk or reduced comfort for the person in question, countermeasures can be initiated so that safety and comfort are increased. The countermeasures can be adapted to the respective person so that, for example, comfort is increased for all people in the interior. It is also possible for a driver to determine a risk or reduced comfort of another person in the interior, whereby, for example, the environmental parameters causing the risk or reduced comfort do not prevail for the driver, which is why his quality of life value is not affected.

For example, some or all environmental parameters are determined generally or separately for each of the seats, i.e., for example, measured and/or derived, in particular based on certain data. A large number of different environmental parameters are expediently used to determine the quality of life values. In particular, different measurement and/or sensor data 10 are fused, each of which is used to describe one of the environmental parameters. For example, one, some or all environmental parameters are additionally used for the operation of other components of the motor vehicle, such as controlling the respective component. This reduces the amount of additional hardware required. For example, one of the environmental parameters is derived from measurement data from a sensor that is used to detect or determine a situation in the motor vehicle, and/or the environment of the motor vehicle is described by means of an environmental parameter, so that the environmental parameter is, for example, an outside temperature.

The respective quality of life value is determined, for example, using a model. It is particularly preferred to use an "artificial intelligence" algorithm to determine the respective quality of life value, preferably a neural network that is trained by a manufacturer of the motor vehicle, for example, or that is at least trained when the motor vehicle is in operation. This improves adaptation to the user(s) of the motor vehicle.

For example, the respective quality of life value is only used when the motor vehicle is started, in particular when the journey begins. However, the quality of life value is particularly preferably determined several times, for example continuously, so that after determining the respective quality of life value, it is essentially immediately re-determined, with new environmental parameters being used as appropriate. Alternatively, there is a time period between determining the respective quality of life value and the associated determination of the environmental parameters, which time period is expediently constant. The time period is preferably greater than 5 seconds and less than 2 minutes. In particular, the time period is between 30 seconds and 1 minute. In this way, effort is reduced, with a deterioration in the respective quality of life value being recorded comparatively.

For example, the respective quality of life value is determined for all seats. Alternatively, this only occurs when a person is on the respective seat, i.e. is using the seat and sitting on it. This reduces the effort. The respective quality of life value is particularly preferably determined depending on the person on the respective seat. The determined quality of life values therefore differ for different people, even if the environmental parameters are the same. As a result, it is possible, for example, to take into account the comfort level of individual people and/or to take into account that different environmental parameters lead to different risks for different people.

In particular, the person sitting on each seat is classified. Using classes reduces the amount of work involved. In summary, each person sitting on each seat is assigned to one of the classes. For example, adults are assigned to one of the classes, children to another class and/or people in need of assistance to another class. This takes into account the fact that not all people can operate the vehicle in the same way and thus can influence the environmental parameters in the same way.

For example, it is possible to manually enter the characteristics of the person on the basis of which the respective quality of life value is determined, or these are retrieved, for example, in particular from a server, or from a device worn by the person, such as a smartphone. This makes it possible to individualize the determination of the quality of life value. Alternatively, the characteristics of the person used to determine the respective quality of life value are determined using the sensor device itself. This reduces the effort required by a user of the motor vehicle, in particular the person. The height and/or weight of the person are expediently determined using the sensor device. Preferably, the age is also determined, and the respective quality of life value is determined depending on the age, with the respective age being derived in particular from measurement data created or received using the sensor device.

Preferably, solar radiation is used as an environmental parameter, in particular whether and to what extent the respective seat is currently exposed to the sun. If this is the case, it will heat up more. This affects the comfort and risk of a person sitting on the respective seat. Alternatively or in combination with this, air quality is used as an environmental parameter, in particular oxygen concentration. If there is a lack of oxygen, a person sitting on the respective seat may be comfortable or at risk, which is therefore taken into account when determining the respective quality of life value.

In particular, it is possible that different air quality prevails in different seats due to different settings of an air conditioning system or ventilation or the like.

Alternatively or in combination with this, a volume is used as one of the environmental parameters. This is measured, for example, in particular using a microphone, or derived, for example, from a setting on a multimedia system (audio system). For this purpose, a volume setting on the multimedia system is queried using the sensor device and the respective environmental parameter is determined from this. In particular, it is possible for a loudspeaker assigned to a seat to be controlled at an increased volume using the multimedia system. This is the case, for example, for the driver of the motor vehicle if the loudspeaker assigned to the seat on which the driver is sitting is controlled comparatively quietly or is switched off. It is also possible that ambient noise, for example, leads to different levels of comfort loss on the seats. For example, the volume on the seats of the motor vehicle that are on the side of the interior that are adjacent to a construction machine in operation is higher than on the other seats. This is therefore taken into account when determining the respective quality of life value.

Alternatively or in combination with this, a temperature is used as an environmental parameter. This is measured in particular or derived, for example, from an air conditioning or ventilation setting. In particular, at an elevated temperature, there is a risk or at least a reduction in the comfort of the person sitting on the respective seat, which cannot be assessed by a driver of the motor vehicle, for example. If the person sitting on this seat is a small child, it is not possible for them to change the air conditioning setting, so that the procedure determines that the small child is at risk.

For example, depending on the respective quality of life value, a function of the motor vehicle is carried out, the execution of the function is initiated or at least adjusted. For example, if the quality of life value is reduced, in particular due to an increased temperature, the setting of an air conditioning system or the like assigned to this seat is changed. However, it is particularly preferred that a message is issued depending on the respective determined quality of life value. This occurs, for example, always or only when the quality of life value is lower than a certain limit. Preferably, several such limit values are present, so that the quality of life value is output in stages or traffic lights. The driver of the motor vehicle can thus make the appropriate adjustment. This enables the interior to be individually adapted.

For example, the message is issued acoustically, in particular via a loudspeaker assigned to the interior, which is also used, for example, by any multimedia system. Alternatively, a separate loudspeaker is used. Alternatively or in combination with this, the message is issued visually, for example on a display of the motor vehicle, which is in particular within the field of vision of the driver of the motor vehicle. In a further development, the message is issued on a smartphone, for example. For this purpose, a corresponding message is sent to the smartphone so that the message or the quality of life value is issued by the smartphone. In particular, the message contains the request that the quality of life value be issued by the smartphone so that the smartphone is at least partially controlled by means of the message. This means that a user of the motor vehicle can also capture the message if the user is not in the interior.

For example, the message is always issued, even if there is at least one adult in the interior. Preferably, the message is issued when the motor vehicle is locked, in particular from the outside. In this case, the message is only issued, or at least also issued, if there is still a person in the interior, which is determined in particular using the sensor device. Suitably, the message is issued on the smartphone that is assigned to a user of the motor vehicle, such as the driver.

The interior is a component of a motor vehicle, which is in particular land-based and which is, for example, a lorry, bus or preferably a passenger car. Several seats are arranged in the interior, which is also referred to as the passenger compartment. Several seats are arranged in the interior. For example, the seats are a component of the interior or are merely located in it. For example, one or more of the seats is designed to be adjustable by an electric motor, so that adjustment is possible for a user/person sitting on it. In particular, the seats are arranged in one or more rows that are located one behind the other in the longitudinal direction of the motor vehicle. In particular, only two of the seats are assigned to the first row, one of which is a driver's seat and the other a passenger seat. The other seats are combined in particular to form benches that have two or three of the seats. Alternatively, for example, the first (seat) row is also formed by means of a bench, by means of which two or three of the seats are provided.

The interior also has a sensor device for determining environmental parameters for the interior. The sensor device is suitable for this purpose, in particular provided and set up. The environmental parameters are measured directly by means of the sensor device, for example, or corresponding measured values are measured, based on which the respective environmental parameter is derived so that it is determined. Alternatively or in combination with this, the sensor device has an interface for coupling to other components of the motor vehicle, in particular a bus system and/or an on-board computer. During operation, the environmental parameters are queried by means of the sensor device, for example via the bus system or from the on-board computer. The environmental parameters are measured using a corresponding sensor or the like. At least the environmental parameters are made available via the bus system or from the on-board computer so that they can be queried and thus determined using the interface. For example, the sensor device is formed by means of the interface.

The interior is operated according to a method in which environmental parameters for the interior are determined using the sensor device. A quality of life value associated with the respective seat is determined on the basis of the environmental parameters. The interior expediently has a control device that is suitable, in particular intended and set up, to carry out the method. The control device comprises, for example, an application-specific circuit (ASIC) or particularly preferably a computer that is suitably designed to be programmable. In particular, the control device comprises a storage medium on which a computer program product, also referred to as a computer program, is stored, wherein when this computer program product, i.e. the program, is executed, the computer is prompted to carry out the method.

The sensor device has, for example, a camera that forms a sensor of the sensor device. The camera is particularly sensitive in the visible and/or infrared spectral range of light. The detection range of the camera is expediently directed into the interior of the motor vehicle, and/or the camera is integrated in a roof liner of the interior or, for example, a dashboard. The environmental parameter is determined in particular by evaluating the images created by the camera. For example, the sensor device has only one such camera. Preferably, however, the sensor device comprises several such cameras. This also makes it possible to monitor essentially the entire interior, or at least the areas of the interior that are not monitored by the cameras are reduced.

Alternatively or in combination with this, the sensor device has an ultrasonic sensor. During operation, this is used to emit ultrasonic waves into the interior, which are reflected and/or scattered by objects located in the interior, such as people or boundaries, and/or depending on the conditions prevailing in the interior. The ultrasonic waves are detected by a receiver of the ultrasonic sensor and the environmental parameters in particular are determined from this. For example, air humidity is determined as an environmental parameter based on the travel time of the ultrasonic waves. In a further embodiment, the sensor device comprises, for example, a thermometer, by means of which a temperature is expediently detected. The sensor device preferably comprises several such thermometers, wherein the thermometers are expediently assigned to different seats.

Alternatively or in combination with this, the sensor device comprises a radar sensor and/or a lidar sensor. During operation, this emits electromagnetic radiation, i.e. radar waves or light, which is reflected and/or scattered in particular by an object in the interior, such as a person. These scattered/reflected electromagnetic waves are received by a respective receiver and the respective environmental parameter is determined from this. Furthermore, it is possible to use such sensors to determine whether there is a person on the respective assigned seat. Alternatively or in combination with this, the sensor device comprises a sensor for determining the oxygen concentration and/or a microphone.

Preferably, the sensor device comprises several of the above-mentioned sensors, which work in particular on the basis of different physical principles. Thus, when determining the respective quality of life value, a comparatively large number of influencing factors are taken into account, so that comfort and/or danger for a person can be determined comparatively precisely.

The invention also relates to a motor vehicle with such an interior. The invention also relates in particular to a control unit. The control unit is suitable, in particular provided and set up, to carry out the method.

The computer program product comprises a number of commands which, when the program (computer program product) is executed by a computer, cause the computer to carry out a method for operating the interior of a motor vehicle. Several seats are arranged in the interior. In the method, environmental parameters for the interior are determined using a sensor device. A quality of life value associated with the respective seat is determined based on the environmental parameters.

The computer is expediently a component of a control device and is formed by means of it, for example. The computer preferably comprises a microprocessor or is formed by means of it. The computer program product is, for example, a file or a data carrier that contains an executable program that automatically executes the method when installed on a computer.

The invention further relates to a storage medium on which the computer program product is stored. Such a storage medium is, for example, a CD-ROM, a DVD or a Blu-Ray disc. Alternatively, the storage medium is a USB stick, an SD card or another memory that is, for example, rewritable or can only be written to once. Such a memory is, for example, a flash memory, a RAM or a ROM.

The further developments and advantages explained in connection with the method are also to be transferred mutatis mutandis to the interior / the motor vehicle / the control unit / the computer program product / the storage medium as well as to each other and vice versa.

An embodiment of the invention is explained in more detail below with reference to a drawing. In the drawing:

• 1 from a bird's eye view schematically a motor vehicle with an interior,
• 2 a method for operating the interior.

Corresponding parts are provided with the same reference numerals in all figures.

In 1 A motor vehicle 2 in the form of a passenger car (car) is shown schematically simplified in a top view, i.e. from a bird's eye view. The motor vehicle 2 has several wheels 4, by means of which contact with a not shown in detail. The wheels 4 are connected by means of a chassis to a body 6, by means of which an interior 8 of the motor vehicle 2 is surrounded. In the interior 8, several seats 10 are arranged, in the example shown, five seats 10. The seats 10 are combined in two rows, which are arranged one behind the other in a direction of travel of the motor vehicle 2. Two of the seats 10, namely a driver's seat and a passenger seat, are assigned to a first (seat) row. The remaining three seats 10 are combined to form a bench seat.

The seats 10 are a component of the interior 8, which further comprises a sensor device 12. The sensor device 12 has a camera 14, the detection range of which is directed into the interior 8 and which covers all of the seats 10. The sensor device 12 also has an ultrasonic sensor 16, by means of which, during operation, ultrasonic waves are emitted into the interior 8, which are reflected and/or scattered by objects located in the interior 8, such as the seats 10. A portion of the reflected/scattered ultrasonic waves are guided back to the ultrasonic sensor 16, which detects them. Based on the time period between emission and reception, it is possible to derive current conditions in the interior 8. The sensor device 12 also has a radar sensor 18 and a lidar sensor 20, by means of which radar waves or light are emitted into the interior 8 during operation, which, like the ultrasonic waves, are reflected and/or scattered by objects located in the interior 8. A portion of them is then sent back to the respective sensor 18, 20, so that current properties of the interior 8 can be determined based on the time period between emission and reception.

A sensor 22 for determining the air quality in the interior 8 is arranged on a roof liner of the interior 8. The sensor 22 for averaging the air quality, which is also a component of the sensor device 12, is used to determine a current oxygen concentration in the interior 8. Furthermore, two thermometers 24 and two microphones 26 of the sensor device 12 are integrated into the roof liner and are located between the rows of seats, with the two thermometers 24, as well as the microphones 26, being offset to different sides of the interior 8.

The interior 8 further comprises a control unit 28 which comprises a computer 30 in the form of a programmable microprocessor. In addition, the control unit 28 comprises a storage medium in the form of a memory 32 on which a computer program product 34 is stored. The computer program product 34 comprises commands which, when the program is executed by the computer 30, cause the computer to 2 to at least partially carry out the method 36 shown for operating the interior 8 of the motor vehicle 2. In other words, the control unit 28 is suitable, in particular provided and set up, to carry out the method 36, and the interior 8 is operated according to the method 36.

The method 36 is started when the motor vehicle 2 is moved. In a first work step 38, several environmental parameters 40 are determined. One of the environmental parameters 40 is solar radiation 42, which is recorded by means of the camera 14. In the example shown, the sun is shining to the right of the motor vehicle 2 in terms of its longitudinal direction. One of the seats 10 arranged in the first row, namely the passenger seat, and all of the seats 10 assigned to the second (seat) row, are in the area of solar radiation 42. The driver's seat is the only seat 10 that is outside of solar radiation 42. Another of the environmental parameters 40 is air quality, which is determined by means of the sensor 22 for determining the air quality. The sensor 22 for determining the air quality is used to measure an oxygen concentration in the interior 8 and the assigned environmental parameter 40 is determined from this.

By means of the microphones 26, a volume prevailing in the interior 8 is directly measured and this is used as one of the environmental parameters 40. Since the volume is measured on different sides of the motor vehicle 2, two environmental parameters 40 are present, which are assigned to different seats 10, namely depending on the side of the motor vehicle 2. In the same way, the temperature for the different sides of the motor vehicle 2 and thus for different seats 10 of the interior 8 is determined by means of the thermometer 24, so that two environmental parameters 40 are present, one of which applies to the seats 10 on the right side of the motor vehicle 2 and the other to the seats 10 on the left side of the motor vehicle 2. By means of the ultrasonic sensor 16, the radar sensor 18 and the lidar sensor 20, further properties of the interior air, such as the air humidity, are determined as respective environmental parameters 40. In summary, several environmental parameters 40 for the interior 8 are determined by means of the sensor device 12.

In a second work step 44, which is carried out before, at the same time and after the first work step 38, the sensor device 12 is used to check which of the seats 10 a person 46 is sitting on. In the example shown, a person 46 is sitting on one of the seats 10 in the first row, namely the driver's seat, and A person 46 is also sitting on one of the seats 10 of the second row of seats, which person is located on the opposite side of the interior 8 with respect to the driver's seat.

The sensor device 12 is also used to determine the properties of the respective person 46. In the example shown, a height and weight of the respective person 46 are derived from the respective measurement data. In particular, the ultrasound sensor 16, the radar sensor 18, the Lida sensor 20 and the camera 14 are used for this purpose. In addition, the respective age of the person 46 is determined based on the measurement data created in each case and the determined height and weight of the person 46. The persons 46 are classified based on these values.

In the example shown, the person 46 sitting in the driver's seat is an adult without any other restrictions I. The other person 46, on the other hand, is classified as a small child.

In a third step 48, a quality of life value 50 is determined for each seat 10 based on the environmental parameters 40. The quality of life values 50 are only determined for the seats 10 on which one of the persons 46 is located. In other words, an assigned quality of life value 50 is determined for the respective seat 10. The quality of life value 50 is better the more comfortable the assigned seat 10 is and the lower the risk for the person 46 located on this seat 10.

In the example shown, one of the environmental parameters 40, namely the temperature, is equal to 20°C, whereby this environmental parameter 40 applies to the driver's seat 10. Another of the environmental parameters 40 assigned to this seat 10, namely the volume, describes a low noise level. Another of the environmental parameters 40 assigned to this seat 10 describes that the seat 10 is not exposed to sunlight 42. However, the environmental parameter 40 that describes the air quality, namely the oxygen content, is comparatively poor because the oxygen content is comparatively low. This environmental parameter 40 is valid for all seats 10.

Based on all environmental parameters 40 applicable to the driver's seat in conjunction with the classification of the person 46 sitting on this seat 10, namely the classification as a driver, the corresponding quality of life value 50 is determined. This is comparatively high, but not optimal because the oxygen concentration is too low.

The quality of life value 50 assigned to the occupied seat 10 of the second row of seats is determined in the same way. However, the sunlight 42 is present there, and a higher noise level has been recorded there by means of the microphone 26, so that the corresponding environmental parameter 40 differs from the environmental parameter 40 assigned to the driver's seat. The increased noise level arises, for example, from a construction machine being operated next to motor vehicle 2. Due to a change in the setting of the air conditioning, the temperature there is also higher than in the driver's seat. This already leads to a deterioration in the assigned quality of life value 50. The quality of life value 50 is also determined depending on the characteristics of the person 46, namely the classification as a small child who is comparatively sensitive. For the small child, the increased temperature and the reduced oxygen content are comparatively uncomfortable and represent a risk, so that the quality of life value 50 is deteriorated. However, since the small child is behind the driver, the reduced comfort and possibly the risk cannot be directly recorded for the driver.

In summary, in the third work step 48, the quality of life values 50 are determined depending on the person 46 located on the respective seat 10. The properties of the person 46 used to determine the respective quality of life value 50 are determined by means of the sensor device 12.

In a subsequent fourth step 52, a message 54 is output by means of a display (not shown in detail) that is located in the driver's field of vision if one of the quality of life values 50 is less than a certain limit value. In other words, the message 54 is output depending on the quality of life value 50 determined in each case. The quality of life value 50 is only output if it corresponds to a severely restricted comfort and/or a comparatively high risk. This makes it possible for the driver of the motor vehicle 2 to change the conditions that prevail in the interior 8 or, if necessary, to remove the small child from the interior 8.

The first work step 38, the third work step 48 and the fourth work step 52 are carried out at intervals of 30 seconds, repeatedly, as long as the motor vehicle 2 is used and there is no change in the position of the persons 46. This means that a further deterioration of the quality of life values 50 for the driver is of motor vehicle 2 without it being necessary for him to turn his head.

The invention is not limited to the embodiment described above. Rather, other variants of the invention can also be derived from this by the person skilled in the art without departing from the subject matter of the invention. In particular, all individual features described in connection with the embodiment can also be combined with one another in other ways without departing from the subject matter of the invention.
