What cars know about your driver

The thing looked clear. At an intersection with the Right-before-left rules, a driver had overlooked the car of the coming from the right driver. But then came out of The right-of-way authorized driver was so rushed quickly from the right pre-Gera, that the alleged accident cause could not react in time. How do you know? Through the data records in the respective vehicles. It would have given only the vehicle tracks at the scene of the accident, would have been spoken, the woman probably guilty.

as soon As you sit in a car, data is collected. What exactly is being stored and who has access to it, don't know the driver. What sounds to the greatest possible degree of Monitoring, can be in the event of accidents or breakdown and is also the best means for the driver to prove his innocence.

When it comes to an accident, can be used all of the data to be something about the circumstances of the accident price, in court. This is also true for cell phone data – if, for instance, whether the driver is talking on the phone during the accident, or a message has been sent. This information to ensure that it doesn't need a warrant, explained the traffic rights activist Daniela Mielchen: "Because data are somewhat Intangible, and you could delete them at any time, can call the police to the rule of "danger in delay" – and the mobile phone take it with him."


harvest But what is ever stored in our cars? And who has access to it? While travel data are collected, has to do nothing with the latest technologies. Even alone, in order for an Airbag to work, it needs the technology on a permanent basis certain information, such as, for example, about changes in speed, the deceleration during braking or the Position of the belt tensioner. This data will be stored in case of an accident the Airbag control unit, you show only a snippet of a few seconds before the event. That is for the vehicle manufacturer as a hedge to technical Defects are excluded.

Really relevant, such data will not be damage, of course, in the case of minor accidents with small Plate. But then, if people are seriously injured or even killed. And they are especially indispensable, if assistance systems take over certain driving tasks or eventually without any Intervention by the driver of a car tax. "Who has slowed down? It was the man, or was it the car?", accident Reconstructionist Michael Weyde, brings the Dilemma to the point.

Weyde, even goes so far that it is not the data gathering itself was a Problem, but that there is hardly any legal requirements, what information the individual manufacturers to collect and who has access to it. Because modern assistance systems can provide a Wealth of information about how a person moves his vehicle.

ignored the driver fatigue warnings, and then nods shortly before the accident? How often the track had to intervene to stop the assistant? The driver accelerates very strongly? He has set the turn signal? "The question is, what information is collected," says traffic rights activist Mielchen.

the Tricks of The manufacturer

For the drivers, it is almost impossible to find out what data there is to his driving behavior. "The manufacturers make the sent. The consent of the customer by promise via services such as "Mercedes Me" or "BMW Connected Drive" a value, for example, fast towing service after an accident," says Reconstructionist Weyde. Hardly, the vehicle owner has accepted the terms of use of these Apps, it also gave hard data to the manufacturer.

Particularly easy, which was calculated by a function which can save lives in an emergency Since April of 2018, new cars must be equipped with automatic emergency call system E-Call. If the driver is unable to call after an accident, self-help, the automatic emergency call.

for this To work, need the cars and a receiver for both GPS and Galileo location data, a cellular antenna, a control device with a permanently installed SIM card, a connection to the Airbag control device and a hands-free system. These conditions make it child's play to transfer all the other data from the vehicle permanently. Auto insurers now offer even cheaper rates if his driving record. The have to have no negative consequences. But when it comes to a court proceeding, can here, too, the information stored in the driver load or unload.

black-box for common data

Weyde, mentions a case in which the manufacturer could damage, had to repair a motor on warranty – because he was able to prove that the holder was not handled the vehicle with care.

The legislature that the unregulated flow of data so far, more or less idly. To create "instead of in advance of conditions, is lagging behind the technology", said Weyde. Since there are no rules, what data to save and which systems are the manufacturer, it is not only for the car owners completely opaque, what you know about his driving behavior.

"In the worst case, you will not be able to prove in court that the car has completely done without the Need of a full – braking-because the stored data to give it." It was, therefore, an important step that is similar to a plane, a black box is installed in each vehicle, provides in a crash consistent data.

This formulation is now for the first Time in a decision of the EU Commission, which envisages from 2022 to assistance systems for all new vehicles.
