DETROIT (AP) — General Motors’ subsidiary Cruise is recalling all 950 of its robotaxi to update software after one of them dragged a pedestrian to the side of a San Francisco street in early October.
The company said in documents posted by U.S. safety regulators on Wednesday. With the updated software, Cruise vehicles will remain stationary should a similar incident occur in the future.
The Oct 2 crash prompted Cruise to suspend driverless operations nationwide. California regulators found that its cars posed a danger to public safety. The state’s Department of Motor Vehicles revoked the license for Cruise. Cruise was transporting passengers without human drivers throughout San Francisco.
In the crash, another vehicle with a person behind the wheel struck a pedestrian, sending the person into the path of a Cruise autonomous vehicle. The Cruise initially stopped but still hit the person. But it then pulled to the right to get out of traffic, pulling the person about 20 feet (six meters) forward. The pedestrian was pinned under one of the Cruise vehicle’s tires and was critically injured.
Cruise says in documents posted by the U.S. National Highway Traffic Safety Administration that it already has updated software in test vehicles. These vehicles are being supervised by human safety drivers. The driverless fleet will get the new software before resuming operations, the company says.
In a statement Wednesday, the GM unit said that it did the recall. The company determined that a similar crash with a risk of serious injury could happen again every 10 million to 100 million miles without the update.
“We strive to continually improve and to make these events even rarer,” the statement said. “As our software continues to improve, we will likely file additional recalls to inform both NHTSA and the public. These recalls will be aimed at updating our fleet to enhance safety.”
Cruise said that after examining its system, it has decided to add a chief safety officer. It will also hire a law firm to review its response to the Oct. 2 crash. Additionally, it will appoint a third-party engineering firm to find the technical cause and adopt companywide “pillars” to focus on safety and transparency.
Problems at Cruise could slow the deployment of fully autonomous vehicles that carry passengers without human drivers on board. It also could bring stronger federal regulation of the vehicles, which are carrying passengers in more cities nationwide.
NHTSA opened an investigation Oct. 16 into four reports that Cruise vehicles may not exercise proper caution around pedestrians. Agency documents cited two injuries, including the Oct. 2 crash. “The complaints involved vehicles operating autonomously and encroaching on pedestrians present in or entering roadways. This also included encroachments on pedestrian crosswalks in the proximity of the intended travel path of the vehicles,” the agency said.
In documents filed with NHTSA, Cruise said its automated driving system was designed in some cases to pull over and out of traffic to minimize safety risks and disruption after a crash. The response is dependent on the characteristics of the crash. But in certain circumstances such as a pedestrian positioned on the ground in the vehicle’s path, pulling over is not the desired response.
The Cruise system “inaccurately characterized the collision as a lateral collision and commanded the AV to attempt to pull over out of traffic, pulling the individual forward rather than remaining stationary,” the company said.
While the Department of Motor Vehicles didn’t elaborate on specific reasons for its suspension of Cruise’s license. The agency accused Cruise of misrepresenting safety information about the autonomous technology in its vehicles. The agency did not provide any further details regarding the nature of the accusations. The revocation followed a series of incidents that heightened concerns about the hazards and inconveniences caused by Cruise’s robotaxis.
The DMV and others have accused Cruise of not initially sharing all video footage of the accident, but the robotaxi operator pushed back — saying it disclosed the full video to state and federal officials.
General Motors Co., has ambitious goals for Cruise. The Detroit automaker had been expecting annual revenue of $1 billion from Cruise by 2025 — a big jump from the $106 million in revenue last year.
GM is temporarily pausing production of the Origin, a fully autonomous vehicle designed for Cruise to carry multiple passengers. The company expects to resume production at a Detroit-area factory once Cruise resumes autonomous ride-hailing.
