Definitions
- the invention relates to a method for determining the driving behavior of a vehicle driver, in particular in local public transport or urban traffic, preferably for use in vehicle fleets, wherein at least one parameter describing the driving behavior is determined. Furthermore, the present invention relates to an apparatus for carrying out the method.
- the driving behavior detected by means of these parameters is compared with an optimal driving behavior, so that the driver can be shown suggestions for improvement in terms of his driving behavior.
- Corresponding systems are used, for example, in vehicle fleets of transport companies in order to increase driving safety, to save fuel and the emission of carbon dioxide and to keep the wear of the vehicles as low as possible. In the systems known from the prior art is problematic that these are extremely expensive due to the complex sensors. Another significant disadvantage is that these systems are not suitable for determining the driving behavior of a driver who is active in public transport or in urban transport. Trips in public transport are characterized by sometimes very short interval trips, namely between two stops.
- the present invention is therefore based on the object, a method for determining the driving behavior of a driver in such a way and further develop that with simple means the driving behavior in any traffic situations can be determined. Furthermore, a corresponding device should be specified.
- the above object is solved by the features of claim 1.
- the method in question for determining the driving behavior of a vehicle driver is characterized in that the position of the accelerator pedal over the course of time is determined as a parameter.
- the underlying object can be solved in a sophisticated simple way by detecting the position of the accelerator pedal, as this previously not taken into account parameters, the driving behavior of the driver reflected.
- this parameter describes the driving behavior in an ideal way, especially in the case of very short interval journeys, as occur in public local traffic or in inner city traffic.
- the position of the accelerator pedal is determined over the course of time, for example over the entire journey.
- Another advantage of the method is that the position of the accelerator pedal is very easy to detect.
- fuel consumption over the course of time can be determined as a further parameter.
- a further significant size is described, so that statements about possible savings of fuel are possible.
- fuel is to be understood in the broadest sense, namely as any energy source that may be provided for a vehicle, for example, gasoline, diesel, electrical voltage, hydrogen, etc. act.
- the change in the position of the accelerator pedal over time can be determined as a further parameter, the change in the position of the accelerator pedal over time. This can be done for example via a corresponding sensor. If the position of the accelerator pedal is present as a function of time, the change in the position of the accelerator pedal can also be determined via the derivation of this function, so that only the position of the accelerator pedal must be detected over the course of time.
- further parameters can be determined. This may be, for example, the position of the vehicle and / or the speed of the vehicle and / or the acceleration of the vehicle and / or the current weather conditions and / or the current traffic conditions and / or the distance to an adjacent, in particular preceding, vehicle ,
- the parameters can be detected by a suitable sensor on the vehicle.
- a sensor system for determining the position of the accelerator pedal can be used over the course of time, for example an inductive or capacitive motion and / or distance sensor.
- the corresponding data can be stored in a memory unit of the vehicle.
- the data can be stored in a relational database management system (RDBMS). This makes it possible to process this data in an ideal way, for example via SQL queries. The further processing of these data can be carried out by a arranged in the vehicle arithmetic unit.
- the data described above be transmitted to a central computer and stored there.
- the transmission can be carried out in an ideal manner wirelessly, for example via a mobile network or a W-LAN.
- the data can be stored in an RDBMS.
- the data is processed further by the central computer in order to display or analyze the driving behavior of the vehicle driver.
- the determined parameters can be set in relation to each other.
- the determined fuel consumption over time as well as the determined position of the accelerator pedal over the time course can be related to each other. Based on this presentation, the driver can be proposed to improve fuel economy.
- the vehicle driver is identified on the basis of the determined parameters. It has been recognized that an identification of the driver is possible in a surprisingly simple way by the evaluation of the data relating to the position of the accelerator pedal. Specifically, the recorded data can be compared with already existing data. The data already available may be data relating to the position of the accelerator over time that is associated with a particular driver. If the recorded data match the already existing data, the driver can thus be unambiguously determined. A match can also be found only in defined, characteristic areas that are particularly suitable for identification.
- the determined actual value of a parameter for example the position of the accelerator pedal
- a desired value of this parameter for example, taking into account a specific route and, if appropriate, taking into account the current traffic situation and / or the current weather conditions, an ideal value of a parameter as the desired value.
- the driver can then be displayed via an acoustic and / or visual and / or haptic display if the actual value corresponds to the desired value and / or if the actual value deviates from the desired value.
- the driver at all times has an ideal "feedback" about his current driving behavior and can adjust this if necessary to achieve an improvement.
- the present invention is defined by the features of claim 13 with respect to a device according to the invention. Thereafter, an apparatus for performing the method according to one of claims 1 to 12 is specified, wherein the device comprises a sensor for monitoring the position of the accelerator pedal. As a result, carrying out the method according to the invention is realized with the least amount of equipment.
- FIG. 1 is a schematic view of a flowchart of an embodiment of the method according to the invention.
- FIG. 2 shows the speed determined over the course of time and the fuel consumption of a first vehicle driver determined over the course of time
- FIG. 3 shows the speed determined over the course of time and the fuel consumption of a second vehicle driver determined over the course of time
- FIG. 4 shows the diagram according to FIG. 2, wherein additionally the position of the accelerator pedal determined over the course of time is plotted, FIG.
- FIG. 5 shows the graph according to FIG. 3, wherein additionally the position of the accelerator pedal determined over the course of time is plotted, FIG.
- Fig. 6 shows the distribution of the relative abundance of different strengths
- Fig. 7 shows the distribution of the relative abundance of different strengths
- Fig. 1 shows a schematic view of a flowchart of an embodiment of the method according to the invention.
- the position of the accelerator pedal over the course of time is first detected by a sensor 1 continuously.
- other parameters can also be detected by the sensor system 1 or a further sensor, by means of which the driving behavior of the vehicle driver can be determined.
- the data detected by the sensor 1 are stored in a memory unit 2 of the Vehicle stored and / or transmitted to a memory unit 3 of a central computer 4.
- the transmission can preferably take place wirelessly-via a mobile radio network or via W-LAN-and in real time.
- the data stored in the database 2 can be further processed by a, for example, arranged in the vehicle, arithmetic unit 5.
- the data stored in the database 3 can be further processed by a computer unit 6 of the central computer 4.
- the further processing takes place in such a way that the driving behavior of the vehicle driver is determined from the data, wherein alternatively or additionally the vehicle driver is identified on the basis of the recorded data.
- the further processed data can be displayed by a display 7 arranged in the motor vehicle.
- the display 7 to the driver for example, indicate whether his driving behavior corresponds to a desired driving behavior, for example, in terms of fuel consumption and / or the prevention of accidents.
- the further processed data for example in the context of a training measure, are displayed in an external display.
- FIG. 2 shows the speed determined over the course of time and the fuel consumption of a first vehicle driver determined over the course of time.
- the speed in km / h versus time t in seconds and in a second curve 9 the fuel consumption in l / h versus time t in seconds are plotted in a first curve 8.
- FIG. 2 shows the typical course of an interval ride, as it takes place between two stops of a bus line. This is characterized by a relatively short total driving time of only about 35 seconds, in which the vehicle accelerates initially up to about 30 km / h, this speed is held only for about 8 seconds and then the vehicle is already back to its speed reduced to finally stop at the next stop.
- the fuel consumption for this ride is about 0.064 liters.
- FIG. 3 shows the speed determined over the course of time and the fuel consumption of a second vehicle driver determined over the course of time, the travel distance being identical to the driving distance on which FIG. 2 is based.
- the speed in km / h against the time t in seconds and in a fourth curve 1 1 the fuel consumption in l / h against the time t in seconds are plotted in a third curve 10.
- the travel time required by the second driver is only marginally shorter than the travel time shown in FIG. 2, namely 32 seconds. It is essential that the first curve 8 and the third curve 10 deviate only slightly from each other, in particular in the range between 0 seconds and 8 seconds substantially correspond to one another.
- FIG. 4 shows the diagram according to FIG. 2, wherein additionally the position of the accelerator pedal determined over the course of time is plotted as the fifth curve 12.
- the position of the accelerator pedal is given as a percentage, with 100% corresponding to the position of a fully actuated and 0% of the position of a fully de-energized accelerator pedal.
- FIG. 5 shows the diagram according to FIG. 3, the position of the accelerator pedal determined over the course of time being also plotted here as the sixth curve 13.
- the comparison of the fifth curve 12 of FIG. 4 and the sixth curve 13 of FIG. 5 shows that they differ significantly from one another over the entire time course, in particular also in the range between 0 seconds and 8 seconds. This makes it clear that the position of the accelerator pedal over time is ideally suited as a parameter for determining the driving behavior.
- FIG. 6 shows the distribution of the relative abundance of the different accelerator pedal operations of the fifth curve 12 shown in FIG. 4.
- FIG. 7 shows the distribution of the relative abundance of the accelerator pedal operations of the accelerated pedal of the sixth curve shown in FIG 13th
- FIGS. 6 and 7 again makes it clear that the first vehicle driver and the second vehicle driver actuate the accelerator pedal extremely differently, namely that the second vehicle driver according to FIG. 7 actuates the accelerator pedal significantly more frequently, ie, more frequently.
- the different driving behavior of the first vehicle driver and the second vehicle driver is very clearly visible on the basis of Figures 6 and 7. This shows that the position of the accelerator pedal over the course of time is an ideal parameter for determining the driving behavior Furthermore, the position of the accelerator pedal can be detected by an extremely simple sensor system.
