Uber ‘disabled braking system’ in fatal crash

Uber had disabled the emergency braking function of the Volvo XC90 which killed a pedestrian in Tempe, Arizona in March. A preliminary report from the National Transportation Safety Board (NTSB) says the car was “operating with a self-driving system in computer control mode” when it struck 49-year-old Elaine Herzberg, who was pushing a bicycle across the road. According to the NTSB report, Uber said “emergency braking manoeuvres are not enabled while the vehicle is under computer control, to reduce the

According to the NTSB report, Uber said “emergency braking manoeuvres are not enabled while the vehicle is under computer control, to reduce the potential for erratic vehicle behaviour”. This means that the driver is relied upon to take appropriate action on the road – however, the system “is not designed to alert the operator”.

Investigators found that the car’s self-driving system registered the pedestrian about six seconds before impact, when the vehicle was travelling at 43mph. The system’s software classified the pedestrian “as an unknown object, as a vehicle, and then as a bicycle with varying expectations of future travel path”. At 1.3 seconds before impact, “the self-driving system determined that an emergency braking manoeuvre was needed to mitigate a collision”.

The NTSB is continuing its investigation to determine the probable cause of the accident, and plans to make safety recommendations to prevent similar incidents. The agency said it was working with Uber, Volvo Cars and the Arizona Department of Transportation “to compile a complete and accurate account of the crash”.

    Most pedestrian detection systems ‘hit pedestrians at 30mph’
    In-car automatic emergency braking systems with pedestrian detection mostly fail to avoid hitting pedestrians - and are “completely ineffective at night”, according to new research. In shocking findings, the American Automobile Association (AAA) revealed that most systems hit a simulated pedestrian target at 30mph. A collision also occurred 89% of the time when a vehicle operating at 20mph encountered a child darting between two cars. In tests, all vehicles collided with an adult pedestrian immediately fo

    Uber’s self-driving cars resume trials in Pittsburgh in manual mode
    Uber’s self-driving cars are being manually driven on public roads in Pittsburgh after a fatal crash which prompted the company to pull out of its testing programme in North America. The company is trialling new safeguards which it says will improve vehicle fleet safety and performance. According to a report by Medium, Eric Meyhofer, head of Uber Advanced Technologies, says: “While we are eager to resume testing of our self-driving system, we see manual driving as an important first step in piloting thes

    Uber to redirect focus to bikes and electric scooters
    Uber intends to focus more on its electric scooter and bike business as it says individual modes of transport are better-suited to inner city travel. Dara Khosrowshahi, Uber’s CEO, believes users will make more frequent, shorter journeys in the future, the Financial Times reports. "During rush hour, it is very inefficient for a one-tonne hulk of metal to take one person ten blocks,” he says.

    Waymo has launched a driverless taxi service in Phoenix, Arizona, where riders will be charged for the journeys they take. In a blog post, CEO John Krafcik says the commercial self-driving service – called Waymo One - is available to early riders who have already been using Waymo’s technology. The company hopes to make the service available to more members of the public as it adds more vehicles and drives in more places, he writes. “Self-driving technology is new to many, so we’re proceeding carefully wi
