The efforts have been moving forward in earnest since early last year, when G.M. bought Cruise Automation, a software company based in San Francisco.
Cruise’s chief executive, Kyle Vogt, said the deal for Strobe would help G.M.’s autonomous vehicles visualize roads and driving conditions, and bolster the company’s overall efforts to advance self-driving technology.
“Strobe’s lidar technology will significantly improve the cost and capabilities of our vehicles so that we can more quickly accomplish our mission to deploy driverless vehicles at scale,” Mr. Vogt said in a statement.
Strobe, which was started in 2014, has fewer than 15 employees, G.M. said, including a small number of software engineers. The company was spun off from the firm OEwaves, which has provided imaging products for use in the defense industry.
The company’s founder, Julie Schoenfeld, said Strobe held patents that would “play a significant role in helping G.M. and Cruise bring these vehicles to market sooner than you think.”
