The present disclosure relates to a transport device with an occupant compartment, comprising at least one sensor for breath gas analysis, at least one position locating device for determining the distance between the sensor and the front side of the head of a compartment occupant, and at least one data processing device.
Using and operating transport devices requires the utmost concentration. In the case of further traffic participants, such as, for example, in road or maritime traffic, it is imperative that the person at the control apparatus of a transport device has unimpaired judgment in order to be able to appropriately react to potential dangerous situations or changing traffic conditions. One cause of traffic accidents which is still not to be overlooked is the influence of alcohol and other drugs and the thereby impaired judgment of the traffic participants. But drowsiness, too, resulting, for example, from exceeding driving time limits, can lead to traffic accidents. Breathalyzers and vehicle operator monitoring systems for avoiding accidents are sufficiently known from the state of the art.
A number of systems include monitoring of vital signs of vehicle operators. DE 100 18 669 B4 discloses a driver state monitoring device for checking the physical state of a driver with a pulse sensor made of electrically conductive material arranged within a steering wheel. Through contact with the skin of the driver, this pulse sensor generates pulse signals which are compared with reference data of the driver in the normal state and communicated to the driver via a display device or audio signals. DE 10 2004 036 119 B4 describes a similar system with a driver assistance system for fatigue detection and attention evaluation of a driver. It is intended for the threat of incident microsleep to be detected through continuous recording of the pulse rate, wherein, upon a sudden change in pulse rate, a warning device is activated which emits acoustic and optical warning signals. Furthermore, an integrated storage device is intended to allow for statements to be made regarding the culpability of the driver in the case of a potentially occurring accident. Aside from their inaccuracy and error-prone nature, it is also a disadvantage of such systems that no statements can be made regarding potential alcohol consumption by the vehicle operator.
Alternative systems rely on determining the alcohol level of a vehicle operator right at the beginning of the drive, such as the system in DE 10 2014 004 961 A1. The device disclosed therein presents a hand-held device with a mouthpiece for taking a breath or saliva sample as well as an analysis unit for determining the alcohol concentration. In this case, the device is coupled to an immobilizer of the vehicle which prevents the starting or the operation of the vehicle. The disadvantage of such a hand-held device is that the breath gas monitoring can only be conducted once at the beginning of the drive, continuous monitoring with a hand-held device is somewhat less feasible due to the hand thus removed from the control device and the view deviating from the road to the display of the hand-held device.
Further systems determine the air concentration inside the vehicle's interior. For example, DE 10 2018 200 003 A1 shows a method for analyzing the breath of vehicle occupants, wherein a time profile of a concentration of a breath gas inside the vehicle's interior is determined and evaluated. Furthermore, the method is intended to allow for measures to be taken to influence the vehicle occupants. The disadvantages of such systems are generally the measurements are averaged across the entire interior of the vehicle. No differentiation is made between breath air and ambient air.
Existing systems for checking and monitoring the driving ability of a driver always leave something to be desired. Thus, there is accordingly a need to be able to determine and check the state of vehicle occupants, such as regarding driving ability and driving fitness, reliably and throughout the entire duration of use of the vehicle, in some cases without negatively affecting the vehicle operator and/or the vehicle occupants.
Accordingly, the present disclosure provides a transport device with an occupant compartment, comprising a control apparatus, such as a steering wheel or steering column, at least one transport device door, a transport device roof, at least one safety belt, at least one transport device seat, at least one, in some cases wireless, headset, at least one headrest, at least one rearview mirror, at least one displaceable, in some cases foldable, sun visor, and/or a dashboard In some cases, the transport device includes a control apparatus, in some cases a steering wheel or steering column, at least one transport device door, a transport device roof and at least one transport device seat as well as optionally at least one safety belt, at least one rearview mirror, at least one displaceable, in some cases foldable, sun visor, at least one headrest, at least one, in some cases wireless, headset, and/or a dashboard, and further comprises:
In an expedient configuration of the transport device according to the present disclosure, it is provided that the at least one sensor, in some cases the plurality of sensors, for breath gas analysis is adapted and arranged to qualitatively and quantitatively identify at least one substance selected from the group consisting of alcohols, such as ethanol, ketones, such as acetone, aldehydes, carboxylic acids, carbon oxides, nitrogen oxides, oxygen, hydrogen, water, and mixtures of these substances. Using the determination of the ethanol content, it can be established whether the vehicle operator can still be permitted to start the transport device. If, for example, the presence of hydrogen and/or ketones is detected, it is possible to draw conclusions about metabolism problems, which, if present, also contraindicate the starting and/or operation of the transport device. This, in operative connection with the data processing device, can lead to activation of the device for blocking the transport device and/or of an information output unit, depending on the predetermined setting of threshold values or threshold ranges.
Accordingly, it can be provided that the at least one sensor, in some cases the plurality of sensors, for breath gas analysis is or comprises an alcohol sensor, and/or that the at least one sensor, in some cases the plurality of sensors, for breath gas analysis is adapted and arranged to detect engine combustion gases.
In an expedient configuration the at least one sensor, in some cases the plurality of sensors, for breath gas analysis is adapted and arranged to determine the breathing rhythm, the depth of breath, and the breath frequency of the compartment occupants of the transport device, in some cases of the compartment occupant at the control apparatus. This allows, for example, for reliable determination of the degree of fatigue of a vehicle operator.
In a suitable embodiment of the transport device according to the present disclosure the at least one sensor, in some cases the plurality of sensors, for breath gas analysis is adapted and arranged to perform a breath gas analysis using a plurality of inhalations, in some cases using only one inhalation, in some further cases an inhalation at rest, of a compartment occupant of the transport device, in some cases of the compartment occupant at the control apparatus. With the transport device according to the present disclosure it is possible to perform the analysis of the breath gas with just one inhalation in order to draw conclusions regarding, for example, the driving fitness of a driver.
In at least one embodiment of the transport device according to the present disclosure, it can be provided that the at least one sensor, in some cases the plurality of sensors, for breath gas analysis is a component of a headset or sensor module. In this case, the transport device is one in which the headset or sensor module is removable, in some cases reversibly, from the control apparatus, the transport device door, the transport device roof, the safety belt, the transport device seat, the headrest, the rearview mirror, the sun visor, and/or the dashboard, wherein it is, in some cases, reversibly removable from the control apparatus, the transport device door, the transport device roof, the headrest, the rearview mirror, the sun visor, and/or the dashboard.
The at least one sensor for measuring at least one vital sign can be expediently adapted and arranged to determine the pulse, the heart rate, the skin conductance, the oxygenation of the blood, the sweat quantity, and/or the sweat composition of a compartment occupant, in some cases of the compartment occupant at the control apparatus.
With the transport device according to the present disclosure it is further possible in one embodiment to perform compartment occupant-specific measurements with the at least one sensor for breath gas analysis and/or the at least one sensor for measuring at least one vital sign.
In this case, it can be expediently provided that the at least one position locating device for determining the distance between the sensor and the front side of the head of a compartment occupant, in some cases the compartment occupant at the control apparatus, comprises at least one camera and/or infrared system.
In a further configuration, the transport device according to the present disclosure can further comprise at least one temperature sensor which is adapted and arranged to determine the temperature in the occupant compartment, and/or at least one humidity sensor which is adapted and arranged to determine the humidity in the occupant compartment, and/or at least one sensor which is adapted and arranged to determine the moisture in the exhaled breath of a compartment occupant, in some further cases of the compartment occupant at the control apparatus, and/or at least one flow sensor which is adapted and arranged to determine the airflow in the occupant compartment, in some cases if a ventilation or heating device is switched on.
In an expedient embodiment of the transport device according to the present disclosure, it is provided that the sensors, in some cases the sensor for breath gas analysis and/or the sensor for measuring the at least one vital sign, are adapted and arranged to determine measurement values, in some further cases the alcohol concentration, at the beginning of a transport and/or at defined temporal intervals during a transport, of a compartment occupant, in some cases of the compartment occupant at the control apparatus, and to transmit these values to the data processing device. In at least one configuration, the data processing device is adapted and arranged to compare the measurement values with stored reference values. In this case, the data processing device is adapted and arranged to activate the device for blocking the transport device and/or the information output unit upon determining a value which is higher than a stored threshold value.
In at least one configuration, the information output unit can be present in the transport device. Alternatively or additionally, the information output unit can also be present outside of the transport device and, for example, be wirelessly connected or connectible to the data processing device, for example with a hospital, an emergency medical station, a police station, and the like.
Furthermore, such transport devices according to the present disclosure have proven to be suitable which additionally have at least one camera unit, in some cases in operative connection with the data processing device, said camera unit being adapted and arranged for facial recognition of the driver of the transport device and/or of at least one occupant in the transport device and/or for recognizing the position of the mouth and/or nose relative to the at least one sensor.
The transport device according to the present disclosure can, for example, be selected from the group consisting of passenger motor vehicles, cargo motor vehicles, buses, trains/trams, ships, airplanes, forklifts, motorcycles, such as three-wheel motorcycles, and agricultural machines.
Using the transport device according to the present disclosure, it is surprisingly possible to reliably determine the state of driving fitness of an occupant of a transport device, such as of the vehicle operator, and, in response to the data determined and evaluated using a data processing device, to directly or indirectly make the occupant or occupants, such as the vehicle operator, aware of possible dangers and impairments to operating the transport device, or to prevent the starting or continuation of the actuation of the transport device. In this way, possible dangerous situations, for example too high a blood alcohol content or incurring fatigue, can very precisely be identified early and the risk of harm to humans and the environment can be significantly reduced.
