Definitions
- the object of the invention is to provide an improved method for determining the number of persons in a vehicle.
- the invention is based on the objects of specifying a computer program and a computer-readable medium.
- a state of motion of a vehicle is recorded. Furthermore, measured values of a characteristic variable are recorded according to a query frequency.
- This characteristic variable relates to a weight of the vehicle.
- the characteristic variable can relate to a spring load of a spring of the vehicle.
- the characteristic variable relates to a spring length. or a spring pressure.
- the method according to the invention provides that the query frequency is varied on the basis of the recorded movement state of the vehicle.
- a number of people within at least part of the vehicle is calculated. This calculation is carried out in a manner already known to the person skilled in the art. Furthermore, it is provided that the calculated number of people is output.
- the calculated number of people is initially output to a vehicle control system of the vehicle. In this way, reliable and efficient control of an air conditioning system is made possible. Furthermore, it can be made possible to output a distribution of passengers in the vehicle by means of an optical display. In this way, the passengers can be guided to less occupied sections of the vehicle. In addition, an even distribution of passengers within the vehicle can be achieved in a simple manner. Alternatively or additionally, it is conceivable that the calculated number of people is transmitted to a land side by means of a mobile radio network. This makes it possible to improve operational organization. For example, depending on the utilization of a vehicle, corresponding capacities can be prepared or redistributed.
- the proposed method makes it possible to determine the number of people in a vehicle with increased accuracy. In particular, a deviation between the number of people determined by the method and the actual number of people can be reduced.
- an advantageous development provides that in the case of a first driving speed of the vehicle, a higher query frequency is selected than in the case of a second driving speed of the vehicle, which is greater than the first driving speed.
- the query frequency is selected inversely proportional to the driving speed.
- the query frequency is selected discontinuously in predetermined steps based on predetermined driving speeds. A variance of the measured values that increases with increasing driving speed, for example due to environmental influences such as wind or unevenness of a road, thus has less influence on the calculation of the number of people.
- the query frequency is varied based on a changing movement state of the vehicle. In this way, it is possible to keep a number of measured values that are negatively influenced due to changes in the movement state small.
- the query frequency is reduced in the event of a change in driving speed.
- the influence of acceleration and/or braking of the vehicle, which distorts the determination of the number of people, can be reduced or even prevented at low cost.
- the query frequency is selected to be higher than in the case of a a changing direction of travel. This makes it possible to increase the reliability of the process.
- the query frequency is varied based on an amount of an acceleration component acting transversely to the direction of travel of the vehicle.
- the query frequency is varied based on an amount of an acceleration component acting essentially perpendicularly to the direction of travel of the vehicle.
- the query frequency is varied based on an amount of an acceleration component acting essentially perpendicularly and horizontally or vertically to the direction of travel of the vehicle.
- a higher query frequency is selected than in the case of a second magnitude of the acceleration component, which is greater than the magnitude of the acceleration component. It is conceivable here that the query frequency is selected inversely proportional to the magnitude of the acceleration component. Alternatively, it is conceivable that a query frequency is selected discontinuously on the basis of predetermined magnitude values of the aforementioned acceleration component. In this way, a particularly precise and flexible method for determining the number of people in a vehicle can be provided.
- the query frequency is reduced in the event of a changing magnitude of the acceleration component.
- the influence of possible rolling or swaying movements during or after cornering of the vehicle can thus be easily limited.
- an advantageous further development provides that the query frequency is varied based on the gradient of a route. Negative influences of an uphill or downhill journey on the measured values of the parameter can thus easily be taken into account.
- a spring length of a spring of the vehicle is selected as the characteristic value.
- the spring mentioned is to be understood as an elastic device for the purpose of dampening shocks during a journey.
- a spring pressure of the spring of the vehicle is selected as the characteristic value. This enables reliable and cost-effective recording of measured values.
- the method according to the invention can be carried out by means of the vehicle according to the invention.
- the vehicle has a sensor device of the second type.
- This is designed to detect values of a parameter which relates to a weight of the vehicle.
- the sensor device of the second type expediently has several sensors. These sensors of the sensor device of the second type preferably detect a spring load of springs of the vehicle. For example, by means of a sensor the sensor device of the second type detects a spring length or a spring pressure.
- the vehicle is designed as a passenger transport vehicle.
- the invention provides a computer program which, when executed, causes the data processing device of the vehicle according to the invention to carry out the method according to the invention.
- the invention further provides a computer-readable medium. This has instructions which cause the data processing device of the vehicle according to the invention to carry out the method according to the invention.
- the computer-readable medium can be, for example, a CD-ROM, a DVD, a USB or flash memory or a non-physical medium such as a data stream and/or a data carrier signal.
- FIG 1 is a schematic illustration of an example of the method according to the invention.
- FIG 2 shows an embodiment of a vehicle by means of which the method according to the invention can be carried out, as well as a special embodiment variant of the example of the method illustrated in FIG 1.
- FIG 1 illustrates an example of a method 100 in a schematic representation.
- a number of people in a vehicle 10 is calculated 108 based on a weight of the vehicle 10.
- a state of motion of the vehicle is recorded 102.
- measured values of a parameter are recorded 104 which relates to a weight of the vehicle 10.
- These measured values are recorded 104 according to a query frequency which is varied 106 depending on the state of motion of the vehicle 10.
- the query frequency mentioned is varied 106 on the basis of the detected 102 movement state of the vehicle 10.
- the query frequency is selected to be higher when the vehicle 10 is at rest than when the vehicle 10 is in motion.
- FIG 2 shows an embodiment of a rail-bound vehicle 10 in a schematic representation.
- This vehicle 10 is in particular the vehicle 10 already described in connection with FIG 1.
- FIG. 2 illustrates a particular embodiment of the example of the method 100 described in connection with FIG. 1.
- a movement state is separately recorded 102 for each wagon 20 of the vehicle 10. Furthermore, the measured values of the distance sensors of the sensor device of the second type 14 are recorded 104 by the data processing device 16 according to a query frequency. The query frequency is varied 106 on the basis of a respectively recorded movement state of each wagon 20 of the vehicle 10.
- the special embodiment of the method 100 provides that the query frequency is reduced 106 as the driving speed increases.
- the query frequency can be selected inversely proportional to the driving speed of the vehicle 10.
- a continuous or discontinuous variation 106 of the query frequency depending on the driving speed is conceivable here. In this way, it is possible to significantly reduce a variance in the measured values caused by the driving dynamics of the vehicle 10.
- the particular embodiment of the method 100 provides that the query frequency is varied 106 based on a changing motion state of the vehicle 10.
- the query frequency is selected to be higher than in the case of a detected change in direction of travel. If the vehicle 10 moves, for example, along a curved course, the example of the method 100 described in connection with FIG. 2 provides that the query frequency is varied 106 on the basis of an amount of an acceleration component acting essentially perpendicular to the direction of travel of the vehicle 10 and in the horizontal direction. For example, in the case of a first amount of the aforementioned acceleration component, a higher query frequency is selected than in the case of a second amount of the acceleration component. component which is greater than the first amount of the acceleration component. This means that when the vehicle 10 is traveling along a slightly curved curve, the query frequency is higher than when the vehicle is traveling along a strongly curved curve.
- the query frequency will be reduced if the amount of the acceleration component changes. Changes in the state of movement will therefore have less of an impact on the calculated number of 108 people.
- the data processing device 16 is used to first calculate 108 separately the weight of each wagon 20 of the vehicle 10 and, based thereon, the number of people within each wagon 20 of the vehicle 10. This calculation 108 is carried out in a manner already known to the person skilled in the art.
