In China, the world’s biggest car market, GM is making vehicles with SAIC Motor, which has also invested in Momenta. Momenta is also backed by Toyota Motor and Daimler AG.
This is the first autonomous driving partnership that the top US automaker has made in China, where it sold roughly three million vehicles last year.
GM is also developing autonomous driving technologies through its subsidiary Cruise. It also has Super Cruise driver assistance technology. Earlier this month, its venture capital arm invested in Oculii, a US startup maker of software for radar sensors used in self-driving cars.
Four-year-old Momenta is among the few companies that hold a permit for gathering high-definition maps in China, a key tool in autonomous driving technologies.
