It is well known that most accidents with pedestrians are caused by the driver being in-alert or misinterpretation the situation. For that reason pedestrian detection systems coupled with driver warning and/or autonomous braking action are recommended to facilitate accident avoidance or reduction of the impact speed. Especially combined active and passive countermeasures that on one hand reduce impact speed and on the other hand protect the pedestrian upon impact (at low speeds) have a high potential to reduce fatalities and injuries.
As stated in the call text: “Unprotected and un-motorized road users suffer the most severe consequences in collisions with vehicles due to the limits of the human body’s tolerance to crashes at a collision speed over 30 Km/h.” Assuming that:
• 50 to 75% of pedestrian accidents are foreseeable, i.e. the pedestrian can be detected and the car braked before the impact
• Forward looking integrated pedestrian safety systems can reduce impact speed by 15 to 20 km/h for pedestrians hit by the front of the car (as claimed by systems currently in the market and using the benefit methodology as developed for the European Commission , it is estimated that integrated pedestrian safety systems could yield a reduction of 15 to 30% in the number of pedestrian road fatalities in Europe upon full penetration into the fleet.
Based on such findings various EU FP projects started developing required pedestrian detection technologies which enabled the development of commercial systems that are now entering the market. However, their actual deployment is limited! The main reason is the lack of public awareness, which, to a very high extent is caused by the fact, that the benefits of such systems have not been quantified yet. Moreover, it is difficult for the average vehicle or fleet owner to see, how investments in integrated pedestrian safety systems will pay off.
Therefore, an essential step for the widespread introduction of integrated pedestrian safety systems is the development and implementation of procedures for their evaluation . As stated by various stakeholders like the eSafety forum wide deployed in the marketplace is required to realise their potential benefits.
PROJECT GOALS:The objective of the EU project AsPeCSS is to contribute to the protection of vulnerable road users by developing harmonized test and assessment procedures for integrated pedestrian safety systems.
The outcome of the project will be a suite of tests and assessment methods for input to future regulatory procedures and consumer rating protocols. Implementation of such procedures / protocols will encourage widespread introduction of such systems in the vehicle fleet, resulting in a significant reduction of fatalities and severe injuries among these vulnerable road users.
Active Safety tests will be developed based on accident scenarios determined from accident analysis. One of the main considerations in this process will be the reproducibility of the test procedure. Also it must be ensured that the test method developed can assess the different technologies used.
Technical limitations of existing sensors and actuators used for integrated pedestrian protection systems will be analyzed. Work will be performed to quantify the uncertainties inherent in pedestrian reaction variability. The results will be used to develop a method to assess the trade-off between effectiveness and unjustified system responses.
Additionally, methods and means to adapt typical crash test conditions to new crash conditions based on the results obtained during the tests of the preceding active safety pre-crash phase will be provided. Regarding the active safety phase, test targets representing pedestrians for different sensor types will be specified if found necessary.
Finally, the effect of different ambient conditions as impact speeds determined from pedestrian full scale simulations will be derived from pedestrian impactor tests (including virtual) for a selection of vehicles representative of the vehicle fleet. New pedestrian impact positions for relevant accident scenarios and changes in impact parameters will be defined.
Significant reductions in fatalities and injuries can be achieved by implementing the project findings and results in future regulatory and consumer rating procedures for vehicle safety. It is well know that consumer rating programmes have a strong influence on manufacturers to build vehicles that consistently achieve high ratings, thereby enforcing introduction of new safety systems that address real world needs into vehicles. Moreover, it will raise the public awareness of the benefits of these integrated safety systems by means of easy understandable rating systems.
The main technical challenge of the project is to develop harmonized and standardized procedures and related tools for the assessment. As part of this, one overall safety assessment will be developed which uses a methodology that balances system benefits from active safety (i.e. pre-impact braking) and passive safety measures.
