Device, means of transportation and method for increasing the efficiency of individual transport

State of the art

The present invention relates to a device, a means of transportation and a

Method for increasing the efficiency of individual traffic. In particular, the present invention relates to a motivation of the users of conventional drive technologies for a change to electrically or purely electrically driven means of transportation.

Many vehicle owners today do not know exactly about their actual usage behavior of vehicles. Therefore, they are reluctant or fear that the range provided by electric vehicles and other features and constraints might be insufficient for their needs. However, independent research on a larger volume of motorists has revealed that for most people, the range of today's electric vehicle would be sufficient. This is especially true when it comes to the use of the vehicle as a second car.

DE 10 2010 032 463 A1, DE 10 2008 046 777 A1 and EP 2 283 469 B1 disclose concepts for analyzing vehicle-related data on the basis of which the vehicle use behavior of lessees can be analyzed.

DE 10 2013 215 978 A1 describes the computer-aided selection of

Equipment components for a new vehicle to be produced for a

Vehicle user of an already produced vehicle is determined that automatically recorded in the already produced vehicle usage data for usage parameters of the already produced vehicle and the usage data are transmitted to a computer system in which equipment data are stored to possible equipment components for the newly produced vehicle. The computer system processes the usage data in such a way that at least one equipment component is selected depending on the use depending on the possible equipment components. DE 10 2013 215 978 A1 describes the computer-aided selection of

Equipment components for a new vehicle to be produced for a

Vehicle user of an already produced vehicle is determined that automatically recorded in the already produced vehicle usage data for usage parameters of the already produced vehicle and the usage data are transmitted to a computer system in which equipment data are stored to possible equipment components for the newly produced vehicle. The computer system processes the

Usage data such that at least one equipment component from the possible equipment components is selected depending on use.

Although it is possible to ask users how they assess their own vehicle use behavior or to quantify those applications in which a purely electrically drivable means of transportation can not provide a sufficient range. However, in the above studies it has been found that sometimes significant deviations of these results to reality occur. Another possibility is to ensure the required range in the electric vehicle through driver assistance.

In particular, for example, the maximum speed can be throttled, a fuel-optimized route proposed and the driving behavior by

Driver assistance systems are made more efficient. However, such systems can only develop their positive characteristics when the user has switched to a suitably equipped electric vehicle. In addition, this feature can not extend the range arbitrarily.

Based on the aforementioned prior art, it is an object of the present invention to provide motivation, from the use of conventional

Drive technologies for private transport on electrically or purely electrically driven means of transport switch. In particular, it is an object of the present invention

Invention to make a realistic assessment of the loss of comfort that arise when switching to electrically or exclusively electrically driven means of transportation.

The aforementioned object is achieved by a method for evaluating driving profiles. It can also be used as a method of increasing the efficiency of

Individual traffic suitable to be understood. Individual transport is understood to mean both individual passenger traffic and freight individual traffic. This can be done for example by cars, vans, trucks or by motorcycle, without the the above examples limit the invention thereto. As is known, internal combustion engine drives with a maximum efficiency in the range of 50% are to be regarded as rather inefficient compared to electric drive systems. In particular, therefore, an increase in efficiency by increasing the percentage of electrically driven

Means of transport on the public road network. According to the invention, a driving profile is first determined by means of the sensor system of a first means of locomotion. The first means of locomotion may be, for example, a passenger car which is at least partly driven by an internal combustion engine and therefore a substantially conventional one

Has range. The sensor system can comprise all hardware, by means of which

Information about the driving profile can (be) determined. For example, you can

Raddrehzahlsensoren, satellites for satellite-based positioning, etc. are used to record the driving profile of the means of transport. The driving profile may comprise the entirety of the journeys of the user with the means of transportation or only those journeys which have a minimum number of similar journeys. Subsequently, it is checked whether the determined driving profile with an electrically driven, second means of transport can be implemented. In other words, the requirements that make the determined driving profile to the electrically powered means of transportation, compared with the properties of the electrically driven means of transport.

For this purpose, the driving profile can be automatically adjusted with a plurality of categories of electrically driven second means of transport. In other words, a comparison can be made of how the categories of the electrically drivable second one

Means of transport correspond to the driving profile. The categories of the means of transportation may include, for example, equipment features (ranges, power, acceleration, cargo space and / or other properties). In other words, it can be checked whether the usage behavior of the first means of transportation by the user could be met by one or more of the predefined categories of second means of transportation. Possibly. It can also be determined which restrictions would mean the use of the second means of locomotion over the first means of locomotion. Subsequently, at least part of the test result is output. For this purpose, a message to the user (e.g., driver, operator) and / or owner of the first

Traveling means are issued in terms of how the driving profile is met by the second means of transport and / or the plurality of categories of second means of transport. For example, those categories of second means of transportation which completely fulfill the driving profile can be listed here. Alternatively or additionally, those purposes of the driving profile of the first means of transportation can be listed, which can not be covered by a category of second means of transport. For example, the number of days on which the driving profile is not covered by the respective category can be output. Alternatively or additionally, the number of kilometers that is not met within the driving profile by the category of second means of transportation can be displayed. Alternatively or additionally, an additional waiting time (for example due to charging processes of an electrochemical energy store) can be summed up, which would result from the use of the category of second means of transportation with respect to the first means of transportation for the user. Other quantitative and qualitative content is also possible for the message to the user, as long as the user is able to determine in which way the use of the respective category of second means of transport meets (or does not fulfill) his actual driving profile. The information situation and thus the potential willingness to opt for a fully electric

To decide means of transportation, increase for the user in this way considerably, whereby the desired increase in efficiency is achieved.

The dependent claims show preferred developments of the invention.

The driving profile can also be understood as a user profile for a vehicle (or several vehicles). For this purpose, it can be determined and / or matched user-specifically. In other words, the use of the first means of locomotion can only be attributed to the above-discussed driving profile if it is sensed that the user considered above is using the vehicle. If, for example, a spouse of the user uses the vehicle, a corresponding memorandum can be stored in the data of the sensor system by which the sensor data added by the spouse remain unconsidered when determining the driving profile of the user in question. With a corresponding evaluation or output of the message can thus be distinguished, whether for the user, his spouse (or other users) or for the means of transport as a family or pool vehicle and a category second

Traveling would be suitable. The identification of the respective user of the first means of locomotion can be carried out by way of conventional sensors (eg vehicle key,

Face recognition, seat position recognition o. Ä.). The driving profile can be determined in the background. For example, it may be determined over a period of predefined length without the user necessarily noticing. For example, in order for the driving profile to best reflect actual user behavior, a period of one month, several months, half a year, nine months or a whole year, or an organizationally determined period (eg, a lease period) Rental period or similar) before the message is output to the user. The same applies to a predefined number of trips or driven kilometers which are used as a precondition for the (automatic) output of the test result. Possibly. It is also possible to define a time before delivery of the means of transportation (eg six months, three months, one month before the end of a lease period) at which the output of the message to the user takes place, for the user's decision for a suitable category electrically drivable second

To influence means of transport in time.

In order to make the method according to the invention as independent as possible of additional hardware and to facilitate the transition to electrically driven second means of transportation for a maximum number of users, provision may be made for outputting the test result or the message within the means of locomotion.

The same can apply alternatively or additionally for the automatic adjustment. In other words, hardware of the vehicle is used for automatic adjustment and / or output of the test result to the user. The hardware may include, for example, a speaker and / or a display device. This does not exclude that alternatively or additionally, the test result or the message is output, for example via a mobile phone of the user, which provides the information required to build the message via a wired or via a

Wireless communication connection has received. Alternatively or additionally, an internet-switched connection to another information processing device of the user (eg PC, tablet, or the like) can be set up and the information processing device used to output the test result or the message. Alternatively or additionally, the test result can also be communicated to the user via an employee of a service workshop. This can offer additional explanations and thus the

Decision of the user for a category electrically drivable second

Continue to influence transportation.

The driving profile may include, for example, a trip length. In other words, the kilometers traveled essentially in one piece are summed up, since these represent an indicator of a required range of the means of transportation used. In addition, the durations of any pauses / refueling stops can be added up in order to investigate their suitability for absorbing external electrical energy. Alternatively or additionally, the route courses which the user has traveled with the first means of locomotion can be recorded and (for example using an Internet-based database). be evaluated. For example, the course of the route can be examined to what extent (cost-effective) public charging stations are available. In particular, it is also possible to examine the position of the charging stations on the route to determine whether the user should / would have been able to use a corresponding charging station when driving on the route. A particularly strong argument for using a category of electrically powered second means of locomotion arises when the second means of locomotion is superior to the first means of locomotion used by the user for extreme operating conditions. These include, for example, a maximum

Speed and / or maximum acceleration, as these are considered special

prestige and, in the event that the category of electrically powered second means of transport promises improvements,

Moving means change are taken. In particular, those places where the first means of transportation lingers for a minimum period of time can also be examined to what extent a suitable energy infrastructure is available. In particular, the frequency with which the means of transportation are turned off at certain dwelling locations may determine whether the user is asked to what extent a suitable one

Energy infrastructure is present at the dwelling locations, before the automatic comparison or the output of the test result or the message to the user takes place. Alternatively or additionally, appropriate information from the Internet or another

Database (e.g., an energy supplier). Frequent places of residence are for example the private address, the working address, a holiday house, a sports club or similar.

The analysis of driving profiles of several first means of transportation, which are used by a closed user group, offers a particularly high potential for increasing efficiency. Since the exchange of vehicles with strangers is so far rather uncommon (apart from car sharing), several vehicles of a family or a circle of friends can be evaluated together to what extent in the future at least one category of electrically driven second means of transport for one of the first means of transport used so far seems appropriate , As already mentioned above, in particular a second car can in the vast majority of cases all

Fulfill driving profiles of a family or a company vehicle pool. For this purpose, the

Driving profiles over time and in terms of their spatial distribution sensory collected and evaluated. Accordingly, the test result or the message to inform the user or all users that in a common

Use of at least one second means of transport all driving profiles or at least a variety of driving profiles would be fully met. For example, for Such regular trips, which are carried out in successive periods by different users of the user group, categories of electrically driven second means of transport in the test result or in the message are proposed. In addition, information can be output to the effect that other trips can be made better, easier or more comfortable, for example, by internal combustion engine driven first means of transport. For example, within the user group, a first user can only travel more than 450 kilometers (eg, to a construction site, a permanent workplace, etc.) on Monday and Thursday, while a second user of the same user group usually only On Friday he takes a longer trip to his holiday home in Tuscany and returns on Sunday evening. In the meantime, within the user group only lengths of less than 200 kilometers at a stretch, which can be driven by purely electrically driven second means of locomotion of almost every category without charging stop arise. Accordingly, a message can be created for the user group, which proposes to maintain in the future only a first internal combustion engine driven means of transport and to purchase a more efficient and sometimes cheaper second means of transport for the remaining trips. By releasing

Calendar data of users of the user group or joint evaluation of the number of kilometers traveled per day, the test result can be created on the broadest possible information base and contribute optimally to increasing the efficiency of individual transport.

Of course, further features of the respective driving profiles / purposes (such as loading, maximum speed, number of driven axles, etc.) may be included in the automatic adjustment of the driving profiles and thus in the test result or in the message to the user (s) Find. For this purpose, the categories of electrically drivable second means of locomotion can therefore not be characterized with regard to their power / range, but also with regard to their load volume / maximum permissible total weight, etc.

The proposed inventions collection of sensor data as well as the automatic synchronization with the driving profiles can bring valuable knowledge outside closed user circles and allow the increase in efficiency of individual transport.

For example, driving profiles can be collected by means of sensors of a plurality of first means of locomotion. These can be loaded, for example, into a central data memory. In particular, the data can be transmitted anonymously with regard to the origin and identity of the user. Subsequently, similarities in the driving profiles can be searched. In other words, a multitude of means of transportation will be involved classified driving profiles classified. Similarities can be traced, for example

Track sections, start and / or destination position, speed traveled

(Maximum speed and / or average cruising speed). Subsequently, the test result or the message is output to the user of the first means of locating to what extent the classified driving profiles are satisfied by the plurality of categories. The sensors do not have to be purely in this case

be installed combustion engine driven driveability. Rather, within the collected driving profiles also those purely electrically driven

Be included means of transport. The more similar sensory, actual driving profiles are, the easier it is for the user to understand that to increase the efficiency of individual transport no loss of comfort or additional costs are to be accepted. For example, the test result or the message to the user of an internal combustion engine driven first means of locomotion display a comparison with such a driving profile of a second, purely electrically powered means of transport, which has the highest degree of similarity with its own driving profile. For example, an electric vehicle from the same location in which the user lives, at similar times of day and over an identical route every day not far from the user's workplace to be parked because the user of the purely electrically powered

Locomotive works near the user. Without divulging personal information about the purely electrically driven means of transportation or its user, the user of the first means of locomotion can now understand which

Speed, which interior temperature, what travel costs, etc. would be expected in connection with the electrically powered second means of transportation, provided that he decides to use a suitable category of electrically driven second means of transport for the trips to work and back. In this way, reliable results can be achieved faster in the inventively proposed automatic adjustment. In particular, actual comparisons can be made with purely electrically driven means of transportation

To motivate users of conventionally powered means of transportation more quickly to change. Optionally, in the event that there is sufficient similarity between two driving profiles (of a first and a second means of transport), the user of the second means of transport can be offered (eg, against a corresponding incentive) his experience with the user of the first means of transportation share. In this way, the personal exchange of experience between the users of the first and the second means of locomotion can take place, whereby the information situation of the user of the first means of locomotion is considerably improved compared to methods known in the prior art. According to a second aspect of the present invention, a device for evaluating driving profiles is proposed. On further consideration, it can also be understood as a device for increasing the efficiency of individual traffic. The device comprises a data input, an evaluation unit and a data output. The evaluation unit can be designed, for example, as a programmable processor, microcontroller or the like. It can be designed as an electronic control device for a means of transportation (eg automobile). The data input can be set up, for example, for information technology linking with the above-mentioned sensors. It can include a bus participant. By means of the data input, the evaluation unit is set up, a driving profile of a first

To detect means of locomotion. Next, the evaluation unit is set up to check whether the driving profile with a second electrically powered means of transport is implemented. Here, the driving profile with a plurality of categories of electrically driven second means of transport can be automatically adjusted. Also in this regard, the category of features (e.g., mileage data, range), body shapes, etc.

include. Finally, the evaluation unit is set up, by means of the data output, which comprises, for example, a bus subscriber and / or a monitor cable, to output a test result or message to a user of the means of transport, by which the user is informed as to the driving profile through one of the plurality of Categories of second means of transport is met.

In this way, the device according to the invention is set up to set up a means of locomotion for carrying out a method according to the first-mentioned aspect of the invention.

According to a third aspect of the present invention there is provided a computer program product (e.g., a data memory) having stored thereon instructions enabling a programmable processor to perform the steps of a method according to the first aspect of the invention. The computer program product can be designed as a CD, DVD, blue-ray disc, flash memory, hard disk, RAM / ROM, cache, etc. and be provided for later installation on an on-board computer / controller of the means of transport.

According to a fourth aspect of the present invention, there is provided a signal sequence representative of instructions that enable a programmable processor to perform the steps of a method according to the first aspect of the invention. In this way, the information technology provision of the instructions for the case put under protection that the necessary storage means outside the

Scope of the appended claims are located.

Embodiments of the invention

Figure 1 shows a car 10 as an embodiment of an inventive

Means in which a user 1 is traveling. Wheel sensors 3 and a GPS antenna 4 are linked as information for environment sensors information technology with a data input 28 of an electronic control unit 2 as an evaluation unit. By means of the GPS antenna 4, the car 10 is able to determine its position and driven routes by means of a satellite 20. The electronic control unit 2 is further

set up to evaluate driving profiles of the user 1 in conjunction with the car 10. By means of the wheel sensor 3, the speed and / or the acceleration of the car 10 can be determined and stored in a (not shown) data memory. In other words, the electronic control unit 2 is configured to perform an automatic adjustment of the driving profile with a plurality of categories of electrically driven second means of transport. The categories may be received from a stationary data store during a previous workshop visit and / or via a wireless communication link and / or updated. Based on the categories, the electronic control unit 2 is arranged to output a message to the user 1 of the car 10 using a central information display 26 as a display unit. Alternatively or additionally, a wired or wireless communication between the

electronic control unit 2 and a user carried by the user 1 Smartphone 27 are used to display the message. Applications for the use of the illustrated car 10 will be described in detail in connection with Figures 2, 3 and 4.

Figure 2 shows a schematic representation of a housing 5, a workplace 6 and a frequent holiday destination 7 of the user of an inventively designed

Means of locomotion (not shown). In addition, a sports field 8 of a regularly visited by the user sports club is shown. In his habitation 5 is the user a household socket 1 1 available, which is hedged with 10 amps. At the workplace 6, it is possible to charge 9 electric drivable vehicles with a higher power at a public charging station. Over a period of half a year, the illustrated route network has emerged as a driving profile for the user's means of transportation. In other words, the user has traveled the illustrated routes at least as frequently that a relevance for an automatic adjustment of the driving profile with a plurality of categories of electrically drivable second

Means of transport and has the prospect of increasing the efficiency of the individual traffic of the user. The user is therefore issued a message that categories of passenger cars of the manufacturer of his current means of transport are available, which have a sufficient range to achieve all the objectives shown and have a sufficient load volume to the sports equipment of the entire family both to the sports field 8 as well (along with other luggage) to the resort 7 to carry. Optionally, the user may be prompted to manually input the presence of the household socket 1 1 or the charging station 9 in order to improve the information situation for the message to be output.

Figure 3 shows a schematic representation of the use of a vehicle pool 12, which consists of two cars 13, two sports cars 14 and two transporters 15. On Mondays, a target position 16 is approached by a vehicle of the vehicle pool 12. On Tuesdays and Thursdays the destinations 17, 18 are served on a round trip. Also on Mondays, a target position 19 is approached and Wednesdays to Fridays, the target positions 21, 22, 23 and 24 are approached in a round trip before the pool vehicle travels back to the starting point. On Mondays to Sundays also a target position 25 is approached. Are recognizable at least three vehicles are required to reach destinations 16, 19 and 25 at the same time on Mondays. However, one of the vehicles used for this purpose can approach the target positions 21, 22, 23 and 24 on Tuesday and Thursday, the target positions 17 and 18 and another vehicle Wednesday to Friday. As a result, three of the illustrated first pool vehicles 13, 14, 15 can be saved, provided that the track lengths are due to a sufficient range without charging interruptions in the case of purely electrically powered means of transport to drive. Correspondingly greater restrictions result when taking into account a maximum loading capacity of the pool vehicles 13, 14, 15, their maximum speed and the body shapes required for the driving profiles. Such a message output to the user (eg a pool manager) can thus support an increase in the efficiency of individual traffic.

FIG. 4 shows steps of an exemplary embodiment of a method according to the invention for increasing the efficiency of individual traffic. In step 100, a driving profile is determined by means of sensors of a first means of locomotion. In step 200 additional driving profiles of further first means of transportation are collected. In step 300, the collected data is anonymized and classified a variety of means of transport comprehensive driving profiles. For example, similarity measures for driving profiles are determined and the determined driving profiles are clustered (as far as possible). In step 400, a driving profile is automatically aligned with a plurality of categories of electrically powered second vehicle. In other words, it is checked or determined how well the driving profile is fulfilled by the properties of a second means of transportation of the respective category.

Finally, in step 500, a message is output as a test result to a user of the first vehicle, which informs the user of the extent to which the driving profile is satisfied by the plurality of categories. The user is thus presented with a selection of categories of electrically driven second means of locomotion, which fulfill the sensory driving profile in the best possible way.

By means of the present invention, the customer is given a recommendation tailored to his personal needs about the potential of fully electrified means of transportation. LIST OF REFERENCE NUMBERS
