Volvo Suffers Another Auto-Stop Safety System Failure In Public Fashion
Autoblog had the chance to sample this system firsthand at the Oregon launch of the S60 earlier this month in similar parking lot tests with different dummies. It performed as-advertised for us, though a few other journalists did record failures of their own – though those lapses were evidently at least partially exacerbated by the drivers giving-in to their instinct to tromp on the brake pedal. Interestingly, Volvo officials themselves cautioned us in advance that the system may not always detect the dummy's presence, in part because it doesn't mimic the behavior of a human (the Pedestrian Detection system is trained to look for human movements – arms swaying, legs moving, and so on). In fact, when we asked if the system would also detect and activate when animals are in the road, officials said that the safety feature has not yet been trained to do so – it is only capable of registering bipeds.
As you may recall, this is not the first failure of Volvo's new auto-stop impact avoidance systems. Back in May, we told you about another incident in which an S60's City Safety auto-brake system test resulted in the car plowing into the back of a semi truck. Volvo later stated that the crash was caused by a "low-voltage event" in the car's electrical system that turned the rear-impact avoidance system off, a flaw that has since been repaired.
See below to watch videos of the PSD failures as well as an official Volvo video explaining how the system is designed to work.
