Integrated solutions for preventive and active safety systems


Volvo Technology gave an extensive presentation on integrated solutions for preventive and active safety systems at the Transport Research Arena Europe in Gothenburg 12 – 15 June 2006.

 

Focusing on the results generated by the PReVENT subprojects INSAFES and ProFusion, the presentation argued that the driver alone can not be considered to be the main cause of traffic accidents. Considering the driver's complex task, it is more fair to say that the cause of accidents is that the traffic environment and the vehicles are not adapted to the driver’s abilities.

 

From the vehicle manufacturers’ side, safer vehicles can be built and systems to help the driver handle his complex driving task can be developed. Navigation systems can help with the navigation task, ABS systems can help stabilise the vehicle and in recent years systems that assist the driver in his manoeuvring task have also become available, such as adaptive cruise control which helps the driver maintain a safe distance to the vehicle ahead.

 

A high-class interface
Such systems put high demands on the human machine interface. There is a need to interface with the driver in an easily understandable way to avoid overloading him or her with information and warnings. For the systems to be really helpful, it is essential that the driver gets the right information at the right time and that system actions are coordinated. If several systems need to present information or warnings at the same time, higher prioritised functions must be able to suppress less urgent information and actions.

 

Sensor Fusion
Different functions often use different types of sensors. When there is more than one sensor, it is possible to combine or fuse the information from the sensors. This has many advantages. If the sensors look in different directions, a more complete coverage area can be obtained and if the sensors are partly overlapping, higher system reliability can be achieved. There are also economic benefits when more than one function can use the same set of sensors. From the functional point of view, providing all functions with the same view of the vehicle environment is beneficial. In that way, they can form a common decision about what to do based on an identical view. For instance: a lane keeping function can be enhanced not only to keep the vehicle in the centre of the lane, but also to adjust the position with respect to vehicles in adjacent lanes.

 

Overall, the main goal of functional integration is to assist the driver and encourage him to drive safer.
