DE10055059A1 - System for collecting and evaluating motor vehicle emission data in which onboard sensor data is transferred to a mobile phone and hence onwards to a PC and the Internet, such data being used to encourage environmental driving - Google Patents

Abstract

Data relating to vehicle usage is collected using an onboard diagnosis or an onboard measurement system. Such data relates to fuel usage and distance traveled and can be used to calculate emission data and maintenance data. The data calculated with such an onboard sensor and diagnosis system is transferred to a mobile phone and then transferred to a central collection point. The collected data can be used by companies, regional and national governments, etc. In addition it can be used to encourage drivers to drive in a more environmentally friendly way by a suitable bonus scheme.

Description

1. Presentation of the problem

The environmental problems are increasing rapidly due to the increase in CO ₂ and other greenhouse gases as well as higher land use and a worldwide increase in the motorization rate. In addition, the rapid development of emerging markets tends to use up the available resources more quickly than was assumed in the 20th century. The use of solar energy will probably not be able to close the gap, especially due to the still poor efficiency of the solar cells. It seems realistic that inexpensive liquid energy; ie fuel with high energy density for mobility will be in short supply if it is not possible to extend the period of use of liquid hydrocarbons. If more time is available for the development of hydrogen energy, stable supply systems could probably arise worldwide that can secure both energy supply and mobility. However, this is not yet within reach.

2. State of the art

There are currently few restrictions on the use of the individual Hydrocarbons such as B. the price regarding consumption, maintenance regulations and others Regulations. The first beginnings through emission test regulations exist for some Decades, relatively efficient regulations related to automotive engineering (i.e. Otto Cars without catalytic converters or with first generation catalytic converters) for approx. 10 years only in the leading industrialized countries.

To make the emissions from the internal combustion engines recognizable, Systems necessary to collect and structure this data. Such devices are available for Not yet. Some recommendations deal with different ones Regulatory systems that do not have the necessary globalization effects bring. The fuel consumption is more or less clear on the fuel gauge in the Vehicle displayed. Only when the tank is filled up again can the consumption with the kilometers traveled can be calculated. Many vehicles today have an ad  which shows the "current" or "average consumption", there is already consumption and driving behavior correlated. With fuel prices continuing to rise, there is more Interest in learning a low-consumption driving style for your own vehicle. A General thrift can only be achieved if everyone is able is to assess and improve his behavior.

3. Measuring system for the assessment of emissions in internal combustion engines

The development of communication and information technology today makes it possible to conduct calls with mobile phones, regardless of location. In FIGS. 1-4 advantageous applications of the technique are listed. The individual figures represent the following applications.

In the future, cell phones ( 1 ) will be able to collect, evaluate and transmit data. They have a keyboard, a display, an interface ( 3 ) for recording parameters and thus correspond to the conditions of a microcomputer. The wireless transmission ( 8 ) of information makes cell phones ideal data acquisition and transmission modules in commercial vehicles. The future control systems in the mobile area can consist of a combination of a measuring system ( 5 ) integrated in the commercial vehicle and a cell phone temporarily used in the system.

The information from the measuring system reaches the display system near the person through cables ( 4 ). B. on the dashboard or in the control panel, where there is a holder ( 2 ) for the cell phone. The driver of the commercial vehicle puts his cell phone in the recording system. The connection to the measuring device is established and the collected or currently accumulating data is adopted. The data is stored in the cell phone or transmitted wirelessly to a central office. Connection to your own PC ( 6 ) or television, for better visual evaluation than on the miniature display of the cell phone, is possible.

4. Comparison and classification of driving behavior

Each commercial vehicle has a typical, average emission based on a driving curve, depending on the type and year of manufacture. Deviations from this average value can occur upwards and downwards due to series distribution, type-specific changes and defects as well as through the individual change of the vehicle through the use of the user. In the future, the vehicle-specific data could be loaded from the Internet ( 7 ). Depending on the maintenance condition of the commercial vehicle and the driving style, more or less pollutants can be emitted. The mobile phone registers the journey and gives the driver on-board information, ie directly in the vehicle, so that measures to reduce emissions can be taken. The direct feedback enables the driver to change his driving behavior and e.g. B. learn and follow a driving style that is as low in emissions as possible. At the same time or after the journey, the characteristic data is transmitted to data centers by mobile phone. Both your own computer and official computers are conceivable here.

5. Introduction of a bonus penalty system

It is obvious that the release of pollutants and greenhouse gases strongly depends on driving behavior.

In the future, the individual driving style would have to be rewarded or punished. In a way Scope is already being made, the AU partially covers this control. Through the Eco tax increases fuel taxes every year, making the decision when buying of a new or used car is driven towards lower-consumption vehicles becomes. Taxation according to emission classes is intended to chew the lower pollutant Drive vehicles.

In the case of heavy commercial vehicles, one is dependent on emissions Mileage tax thought. An on-board diagnostic or an on-board Measuring system (OBD / OBM) should be integrated. With this system it is possible create an incentive for environmentally responsible behavior to achieve that ultimately fewer pollutants are emitted into the environment. The climate change  is braked. Those lost to the state by the reward financial resources, from the so-called revenue-neutral tax legislation, can be recovered through environmental savings, or from the Contributions from non-environmentally conscious road users are offset.

The system can also be implemented effectively across borders. The evaluation of the Emission emissions could e.g. B. a truck driver when leaving a Territory to be charged or favored. After this The polluter pays principle would exceed the intended average Emission limit Money paid into the system after falling below the limit money would be paid out. This would be a fair distribution of the burdens Emission damage created according to the polluter pays principle.

It is likely that in the future the number of cell phones for the general Communication opportunities increase many times over. So there are none additional costs for the introduction of the control system to forward the Data. The actual measuring system in the commercial vehicles does cause costs, is needed anyway for the optimal control and regulation of the machine.
