Self-driving cars are in all the rage right now. The feeling of not getting overwhelmed while driving or overly focused on the directions has made self-driving cars’ space flourishing.
While the outcome of the driving experience is that of contentment, the way vehicles reach that stage is a complex one. An extensive amount of intelligence is required for a car to drive on its own while keeping track of the speed, dodging traffic, and updating humans on the vehicle’s needs. An intelligence that involves several technologies and pieces of machinery coming together.
Achieving the level of automation and time-sensitive intelligence requires accessing and translating massive sets of data into action and insights, thus paving the road for big data in the automotive industry.
In this article, we are going to dive into the origin and role of automotive analytics solutions which goes beyond making the self-driving experience smooth and autonomous. But before we dive into the role of big data for autonomous driving, let us first answer a few questions that you will get asked when you have to detail the technology’s involvement in space.
- What amount of data is generated through a self-driving vehicle?
It is estimated that an autonomous vehicle generates over 4,000 GB data every day divided into separate sections like –
- Camera – 20-40 KB per second
- Radar – 10-100 KB per second
- Sonar – 10-100 KB per second
- GPS – 50 KB per second
- LIDAR – 10-70 KB per second.
- Is the current fleet of autonomous vehicles truly driverless?
In its current state, big data analytics in the automotive industry is completely involved in only till Level 2 of driving automation. A majority of cars that are operative in the self-driving space work in a way that the vehicle performs acceleration and steering while humans monitor all the tasks and take over control whenever they deem necessary.
There will be more than 30 million autonomous vehicles on the road by 2040
The Technicalities of Automotive Data Analytics
Big data and machine learning in autonomous driving runs on sensors built in the cars. The information that comes in from the multiple in-car sensors are processed and analyzed in microseconds, enabling not just a safe movement from point A to point B but also passing information about the road conditions, communicating with other vehicles, and informing the owners about vehicle issues.
In addition to these sensors, there is one other crucial component in the autonomous driving domain: the automotive data analytics software that helps store and analyze the data sets. The software, being connected to a network, passes information from the sensors to the cloud in a way that the response time to those conditions is instantaneous, especially after the introduction of 5G in automotive.
A self-driving car should have sensors, automotive analytics solutions, and a connection to a cloud server. Next, the car should know its location, for which it makes use of GPS. Together, the data that comes from the internal sensors, such as compasses and speedometers, defines the direction and speed.
Once a vehicle knows its location, it gets easy to know what is around it by using lidar and radar to localize itself inside this map. Here, elements like markers, signs, and other obstacles are taken into consideration.
Using the collected data, the driverless car builds strategies for different situations that may occur on the road. Additionally, data sharing between autonomous vehicles aids in avoiding traffic jams, reacting to emergency situations, and taking weather conditions into account.
To sum up, big data in the automotive industry can be used in the following ways –
- Look and sense – get information; plan and respond on the basis of the collected data
- Map the surroundings in detail
- Identify speed, range, and distance through lidar and cameras
- Communicate with other cars to share information.
Now that we have looked into the core of analytics in the automotive industry, let us look into some role of big data in autonomous vehicles through the use cases.
Role of Data Analytics in the Automotive Industry
Big data analytics in the automotive industry has grown to unimaginable levels. Right from powering self-driving cars to building intelligent traffic systems, AI in its different forms has changed how we travel and interact with vehicles. Now while the role of big data in autonomous vehicles can be seen in the manufacturing, price setting, and customer experience space, for this article, we will be looking into the contributions of autonomous driving through data analytics.
Sensing and Perception
Self-driving cars use several sensors like radar, lidar, camera, etc., to collect data about their surroundings. The data then gets processed and analyzed through big data algorithms for creating a detailed environment map to identify objects like traffic lights, other vehicles, and road signs.
Autonomous cars use data analytics in the automotive industry to make real-time decisions on the basis of data that they gather from the in-car sensors. For example, if the car detects another vehicle getting too close, it will use big data to choose the best course of action, either slowing down or stopping.
The industry has been using big data and machine learning to predict others’ behavior in autonomous driving. The technology combination helps the vehicle anticipate movements and problems that might happen with the car and then take timely action to avoid them.
Natural Language Processing
Another use case of automotive industry data analytics can be seen in the cars being equipped with voice recognition technology which enables the passengers to communicate with the car through their natural language. The technology, in turn, helps the car understand and respond to the user’s spoken commands.
The reasons behind growing instances of big data applications in the automotive industry are evident. But at the same time, we cannot negate the fact that automotive analytics solutions are not getting incorporated beyond Level 2. Let us look at some challenges that need an industry-wide solution.
Challenges of autonomous driving through data analytics
The expectations from big data in the automotive industry are growing exponentially, especially as the automotive industry is planning to make Level 4 and 5 mainstream in the coming years. However, there are a number of complications that are yet to be addressed. Let us peek into them.
- Varied data sets – For predictive analytics in the automotive industry to work, the blend of supervised and unsupervised datasets should be proper and repetitive. However, when driving, there are multiple instances where accidents happen because of nobody’s fault. Additionally, numerous events are extremely rare in nature. So the challenge is to create patterns from several of these isolated events.
- Data storage – A recent report by Western Digital found that the storage capacity per vehicle could reach 11 terabytes by 2030. To accommodate this massive amount of data, it is critical for businesses to bring data storage and processing from the cloud to the vehicle itself via satellite transmission.
- Security concerns – Since data-driven automotive vehicles collect data from the public where the expectations from privacy is limited, the users are less likely to be in control of their data, as they won’t be able to opt out of data collection.
Owing to these industry-level challenges in the adoption of big data for autonomous driving, the market expectation is that the self-driving space will reach its maturity in Level 2 before the exploration work starts on Level 3 and above.
Standing at today, there’s a need for automotive data analytics services that would help automated vehicles with this roadmap.
