According to the Sydney Morning Herald, hundreds of lives could be saved if new pedestrian avoidance technology filters its way in to mainstream cars in the near future. Volvo will soon introduce a car that can automatically apply maximum braking to avoid hitting a pedestrian or reduce injuries. The “Collision Warning with Full Auto Brake and Pedestrian Detection” will arrive in the new S60 in 2010. Using a radar and a camera, it can react within 50ms, avoid an impact below 25km/h and reduce speed by 25km/h (at higher speeds). Volvo says its system, also being developed by Audi and Mercedes-Benz, has the potential to reduce injury risk to pedestrians by 83 per cent.
Software was ‘trained’ after analysing 530,000 kilometres of real world driving to recognise people of all shapes and sizes in thousands of scenarios and even take in to account prams and special clothes. Applying the brakes before a collision is intended to help account for the inattention, which Volvo says contributes to 93 per cent of crashes. “In 47 per cent of crashes the driver doesn’t do anything [brake or steer] before the collision”, said Volvo manager of active safety functions Jonas Tisell.
The SMH warns the hundreds of thousands of kangaroos killed on Australian roads each year not to get too excited. Tisell noted that “The next step is handling animals. But the difficulty with animals is that they are shaped by evolution not to be seen.” Pedestrians will still need their wits about them too. The system may not detect a person stepping out from behind a bus or truck and is unable to detect pedestrians at night. The system is as an iterative step in safety improvement.
The Volvo pedestrian detection system is part of a trend towards crash avoidance rather than vehicle occupant protection. Mercedes-Benz is working on an innovative anchor-like metal and rubber-faced airbag that deploys beneath the car on to the road surface when it detects a collision is imminent.
