Pedestrian detection with full auto brake

Pedestrian detection with full auto brake  - Overview - Volvo S60

The all-new Volvo S60 features the ground breaking Pedestrian Detection with Full Auto Brake system. Pedestrian Detection consists of a newly developed radar unit integrated into the car's grille, a camera fitted in front of the interior rear-view mirror, and a central control unit. The radar's task is to detect any object in front of the car and to determine the distance to it. The camera determines what type of object it is.

The full auto brake part of the technology also responds to vehicles in front that are at a standstill or that are moving in the same direction as the car fitted with the system.

The newly developed dual-mode radar's much wider field of vision ensures that pedestrians about to step into the roadway can be detected early on. The camera has higher resolution than the previous-generation auto brake which makes it possible to detect the pedestrian's pattern of movement.

"The auto-brake system requires that the object is confirmed by both the radar and the camera. Thanks to the advanced sensor technology used, it is now possible to increase to full braking power," explains Thomas Broberg, Senior Safety Advisor at Volvo Cars.

"Detecting pedestrians with sufficiently high reliability has been a complex challenge. Our innovative technology is programmed to trace a pedestrian's pattern of movement and also to calculate whether he or she is likely to step into the road in front of the car. The system can detect pedestrians who are 80 cm tall and upwards, that is to say including children."

New technology permits full braking force

In an emergency situation the driver first receives an audible warning combined with a flashing light in the windscreen's head-up display. In order to generate an immediate, intuitive reaction, this warning resembles a brake light. At the same time, the car's brakes are pre-charged. If the driver does not react to the warning and an accident is imminent, full braking power is automatically applied.

This technology has the same limitations as the human eye, and just like us it "sees" less well in the dark and in poor weather.

Pedestrian Detection with Full Auto Brake can avoid a collision with a pedestrian at speeds of up to 21mph if the driver does not react in time. At higher speeds, the focus is on reducing the car's speed as much as possible prior to the impact. The speed reduction is up to 21mph.

Statistics reveal that the car's speed has considerable importance for the outcome of the accident. A lower speed of impact means that the risk of serious injury is significantly reduced. For instance, if speed is cut from 30mph to 15mph, Pedestrian Detection with full auto brake is expected to reduce the fatality risk by as much as 20 per cent and in certain cases by up to 85 per cent.

City Safety

The all-new Volvo S60 also features City Safety as standard, as seen on its bigger brother - the XC60. The system can reduce or even entirely avoid low-speed rear-end impacts at speeds up to 18mph.

Additional safety systems available:

Driver Alert Control (DAC). A unique technology to alert tired and distracted drivers. This function monitors the car's progress between the lane markers and warns the driver if his or her driving pattern changes in a random or uncontrolled way.
Blind Spot Information System (BLIS) helps detect vehicles in the rear blind spot on both sides of the car. A warning lamp beside the relevant door mirror comes on to alert the driver to the danger.
Active Bi-Xenon Lights are articulated headlights that follow the curve of the road. For best possibility illumination when driving in the dark on twisting roads.
Lane Departure Warning alerts the driver if the car runs across the lane markers without the turn indicator being used.
Advanced Side Impact Protection System
Seat-mounted side airbags
Improved Inflatable Curtains
Whiplash Protection System
