German automaker BMW and Chinese online gaming giant Tencent Holdings are joining hands to launch a computing center in China that will help develop self-driving cars in the world’s biggest auto market, the companies said on Friday.

The computing center, which will start operations by the end of the year, will provide cars with data-crunching capabilities to help them drive semi-autonomously and, eventually, autonomously.

The two companies did not disclose the investment in the center. Sources familiar with the deal told Reuters that the center will be built in the eastern city of Tianjin.

The establishment of the center "will support BMW’s autonomous driving development and innovation in China," Jochen Goller, head of BMW's China operations, said in a statement.

"BMW can, therefore, develop autonomous driving solutions that fit better with the specific driving conditions in China."

BMW said the new computing center will leverage Tencent's cloud computing and big data, and provide the automaker with infrastructure needed to develop the autonomous cars.

The Munich-headquartered automaker says it will likely introduce semi-autonomous, or L3 classification, cars in China in 2021 which would need massive computing power to analyze real-time flow of digital information on road and traffic conditions.

Driverless cars need sophisticated data-crunching capabilities as they rely on so-called artificial-intelligence, or neuro-network technology, to help them "learn" from experience and could eventually drive themselves without human intervention.

BMW's planned Chinese computing center follows the opening earlier this year of a similar computing center in Munich.
