Putting pedestrian safety in the driving seat

13.01.2006
Every year in the European Union there are over 9,000 deaths and 200,000 injured victims in road accidents in which pedestrians and cyclists collide with a car. Hoping to improve on these grim statistics, is a cutting-edge sensing system that could ultimately help to save the lives of vulnerable road users (VRUs).

“The concept is relatively straightforward,” explains Dr Marc-Michael Meinecke of Volkswagen, one of the chief partners in the SAVE-U project along with DaimlerChrysler, Mira and Siemens VDO Automotive. “SAVE-U combines sensors such as radar, vision and infrared camera, as well as sensor fusion and actuators to increase safety for pedestrians. The main idea is that the sensors will recognise pedestrians and if a pedestrian has a high probability to collide with the vehicle then automatic braking will be initiated by the system.”

The project set out to develop an innovative pre-impact sensing platform that operates three different technologies of sensors simultaneously, and then fuses their data to protect cyclists and pedestrians under different weather and light conditions. The system comprises a radar network composed of several 24 GHz sensors working in parallel and an imaging system composed of passive infrared and colour video cameras.

A prototype vehicle incorporating the new system has been successfully tested in the United Kingdom. Installed on the car are two cameras – one video and one infrared – as well as the radar device. The system calculates in a matter of seconds the movement of pedestrians within the ‘capture zone’, which can be anything up to 30 metres away from the vehicle. From that point on, the car’s onboard cameras tracks the pedestrians’ movements and this information is correlated with data received from the radar network (such as distance to objects and their speed). SAVE-U can thus identify any pedestrian or cyclist coming within the trajectory of the vehicle and after analysing the situation, warn the driver or apply automatic braking if there is a risk of collision.

The partners opted to tackle the problem of protecting cyclists and pedestrians in three distinct stages: detection of VRUs at sufficient distance covering a relevant set of scenarios; definition and implementation of driver warning and vehicle control strategies to avoid, or at least minimise, the impact of a crash; and defining vehicle-mounted VRU protection strategies in case the crash cannot be avoided.

“Accident statistics from Volkswagen Accident Research in cooperation with the Medical University of Hanover were analysed,” says Dr Meinecke. “One of the main outcomes of the analysis was the conclusion that active hood concepts, external airbags, automatic braking systems, night vision, and other actuators seem to be very sufficient measure to lower the injury level of pedestrians. Within the SAVE-U demonstrator vehicles mainly automatic braking measures are implemented.”

Major advances were made in areas such as object tracking to obtain a robust trajectory, and the development of a deployment algorithm to be able to activate the automatic brakes without false alarms. Aspects of cost reduction and the reduction of sensor size benefited from the close teamwork, says Dr Meinecke.

In August, the project culminated with a special workshop in the United Kingdom showcasing the technology developed over the previous three years. The workshop featured samples of radar sensors and passive infrared video camera integral to the system, as well as demonstrations of the technology in action using two test vehicles (Mercedes E Class and Volkswagen Passat) equipped with the sensing platform, driver warning and vehicle control systems.

While there is clearly a strong demand for such technology to be implemented in vehicles as soon as possible, there is still a long road ahead before the SAVE-U innovations become standard.

“For a start, the sensors have to be shrunk further in size and price to enable them to be integrated in serial cars. The sensor costs will also have to be decreased dramatically to have a chance to make the systems cost effective. And, last but not least, the software components are still not fulfilling the requirements for serial production. I think in the area of pedestrian protection these pedestrian recognition systems will be the main focus of research activities in coming years,” he says.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
