According to foreign media reports, Mark van Rijmenam, big data analyst and founder of BigData-Startups.com, points out that driverless cars will be equipped with a large number of sensors that generate 1 GB of data per second.

Rigimanham expects sensors in driverless cars to be on the cusp of trouble - discovering pitfalls before they occur, and even planning a car to be repaired.

Google CEO Sergey Brin said last year that "ordinary people" will be able to use driverless cars in the next five years. Last fall, the state of California passed a law that allowed unmanned vehicles to drive on the road. GM plans to launch a semi-autonomous Cadillac in 2015.

"With over 1 billion vehicles worldwide and the proliferation of Google's driverless cars, the amount of data generated will be unimaginable," Google said, not the only company developing driverless cars "Said Thilo Koslowski, an analyst at Gartner, a market research firm." By 2020 there will be several affordable driverless cars on the market. "

Rigimanham predicts that all car companies may be developing driverless cars. Mobileye, a Dutch driverless car camera maker, has raised $ 400 million.

In a blog post this week, Rigimannam said, "Google's driverless cars generate a wealth of data that uses these data to determine driving directions and speeds, and even to judge someone may suddenly be ' Coming out. "

Ridgemenham said that if the driverless car generates 1GB of data per second, the amount of data generated each year will be about 2PB (petabytes). He came to this conclusion on the basis of 600 hours (2.16 million seconds) per car per year.

Koslowski disagrees with the idea that every driverless car can generate 1GB of data per second. Although there will be a lot of data transfer between driverless car's internal components, these data will not be stored, so the data is only for the car itself. "Some high-end cars may generate 1GB of data that users may need to analyze hourly, but 1 second does not produce such data 1GB. " There is no doubt that the amount of data generated by driverless cars will be much larger than the current technology.

Kossloski said the car will be equipped with more infrared sensors, cameras and lidar in the future to detect the presence of objects around it. Cars can even talk to each other, "know" the speed of nearby cars and react promptly when a nearby car suddenly turns or brakes. Using computer algorithms and prediction models, the car can even predict whether nearby cars are driving or even driving other drivers to prevent injury.

Korslowski even predicted that future car-generated data would be uploaded to the cloud storage system, and the government could use the data to improve driving safety.

Vehicles equipped with a large number of sensors will be able to detect faults in real time and take steps in advance. For example, the car will promptly inform the driver of potential hazards and prevent any further breakdown. No driver intervention, the car can make an appointment with the repair shop maintenance.

In the future, the data collected by the car "will help car companies find areas for improvement," said Rigimanham, and the time it takes to get a new car to market will be significantly reduced. "
