“Where is the personal data collected by the car used?” This is a headline article from the slow New York Times last month. The headline article responded to Intel CEO Ke Zaiqi and Barclays Bank Brain Johnson's comments on in-vehicle data. Ke Zaiqi said that the amount of data used by a driverless car reached 4000GB per day, and Brain Johnson asserted that no one was The amount of data collected per minute by driving a car reaches 100GB. Let's take a look at the related content with the car electronics editor.

Due to the use of a large number of expensive hardware and software, the difference between the driverless car and the ordinary car, the gap between the two will not be close in the short term. Moreover, specific to collecting, storing, and transmitting data, ordinary cars are not the same as driverless cars. Ordinary cars now only collect a small amount of data, storing less data, and transmitting less data.

More and more cars are equipped with emergency data logging devices to store critical data at the time of the accident - but the data is only recorded and stored in the event of an accident. For example, in the Anjixing system of General Motors, in the event of an accident, the Anjixing system will automatically make an emergency call and send out the geographical location and car parameters at the time of the accident. This function is naturally good.

Of course, it may also bring trouble to the owner. From a few years ago, some people have positioned their spouse through Anjixing (or similar systems such as BMW Assist and Mercedes Embrace). After the Boston Marathon bombings, the police also used such technology to locate suspects.

In-vehicle data collection necessarily involves personal privacy. Especially when connecting a smartphone to a car, private information such as communication records and contacts may be collected.

Not all OEMs consider protecting user privacy when collecting data. The places you have been to are recorded by the in-vehicle navigation system. If the car is equipped with wireless communication technology, then your travel trajectory may be transmitted to the company server that provides the traffic information service. The performance and condition of the vehicle may be The car is collected when it is launched. Whether it is purchased, used or leased, data may be collected throughout the process and the owner cannot control the use of such data.

However, companies such as Otonomo and IBM are helping OEMs improve their data collection processes. In the future, users can freely decide whether to allow vendors to collect certain data, just like using a smartphone.

Unlike ordinary cars, autonomous vehicles (currently mainly low-speed buses or prototypes) process large amounts of data in real time, and a small amount of data is transmitted wirelessly - although much data is stored for later analysis.

At present, it is still difficult for OEMs to balance the relationship between data collection and wireless transmission because the true value of in-vehicle data has not been tapped. General Motors prefers to resell wireless access rights in the form of Wi-Fi or sell data to information service providers.

Car conditions and performance parameters may be a breakthrough. The amount of data is small and can be transmitted only with low bandwidth. OEMs should collect this data and sell it to suppliers to improve product quality.

If automakers can pay more attention to vehicle conditions and performance data, problems such as igniting, unconscious acceleration, and airbags can be solved at an early stage, which can reduce accidental casualties and reduce the cost of recalls. It may be possible to avoid dealing with government regulatory agencies due to vehicle quality issues.

The component supplier pays the vehicle manufacturer to get the vehicle data, and the consumer or the owner can get the vehicle data for free. So personal privacy data is not the core issue of in-vehicle data collection. The key to in-vehicle data collection is that the OEM is responsible for collecting data to better document and manage the performance and usage of the on-road vehicles.

In addition to the car conditions and performance data, collecting a lot of messy data is not good for anyone. You ask the OEM to monitor the performance and operation of your vehicle. Before a safety issue occurs, the OEM must notify you in advance, and nothing more.

Collecting massive amounts of data from drivers and passengers is of little use, and the worse idea is to send these data wirelessly in real time. Some people may ask, is the current unmanned prototype not collecting huge amounts of data at all times? It is to meet the needs of technology development and machine learning, and to collect massive data at any time. This is just a stage in the practical process of driverless technology.

So, don't worry about data collection affecting personal privacy. The goal of car data collection is not you, but your car.

The above is about car electronics - driverless cars must collect 100GB of data per minute? For related introductions, if you want to know more information, please pay more attention, electronic engineering will provide you with more complete, more detailed and updated information.
