Inside Volvo’s drive to end deaths and injuries in its cars

For decades, Volvo has made improving auto safety a foundation of its business — a move that made it famous for a few decades, but did little to help the Swedish manufacturer so far this century. Now that it's purchase by a Chinese auto conglomerate has had a few years to settle, Volvo has begun to make another push for greater safety on the road. Its goal: To eliminate the risks of death or injury to Volvo passengers by 2020, a tight deadline in auto engineering circles. From my visit to Volvo headquarters in Gothenburg, Sweden, I've now seen the technology that Volvo says can meet that goal. The question is how it will put it on the road.

Pedestrian Detection in Darkness

In 2006, Volvo introduced pedestrian detection to help the driver slow the car before an impending collision. Since then, more features were added in 2010 with auto braking, and in 2013 cyclist detection. Next year, the Swedish automaker is extending pedestrian detection capabilities to darkness. This added capability is important for the Scandinavian country because 58 percent of all pedestrian fatalities occur at night, at dusk or dawn, according to STRADA (Swedish Traffic Accident Data Acquisition). And based on data from VTI (Swedish National Road and Transport Research Institute), the traffic fatality rate in the United States is three to four times higher in the darkness as well.

Inside what use to be an underground military bunker, we test drove a vehicle equipped with higher sensitivity cameras. Heading toward a human-shaped obstacle in complete darkness except for the headlights, we were told to maintain 16-mph speed, ignore the audio and visual warnings and not touch the brakes. As we got closer and about to stab the brakes ourselves, the car reacted quickly and stopped the car before we collided with the mannequin. Barely.

Animal Detection

Whether it's moose in Sweden or deer in the United States, thousands of drivers know the dangers of striking an animal at speed. The forces and impact experienced from hitting a moose at 62 mph is like dropping a 1,000-lb weight from the top of a ten-story building. Volvo has determined that any collision with speeds over 43 mph is 70 percent more likely to cause severe injuries. So the goal is to detect the animals early — during daylight or at night — and allow the car enough time to slow itself automatically below the 43 mph threshold, either to avoid the collision completely with steering input by the driver, or lessen the impact and injuries to the occupants if collision is unavoidable. On a test rack onboard the demonstration vehicle traveling 55 mph, a moose dummy a good distance away on the side of the road was detected quickly, allowing enough time for emergency maneuvers.
