The overall number of fatalities in traffic accidents in Europe is decreasing substantially. Unfortunately, the number of fatalities among cyclists does not follow this trend. From the accident statistics it becomes clear that a major share of these killed cyclists in traffic accidents results from a collision with a motorized vehicle. The automotive industry focusses on this issue in terms of passive and active safety. One of the most promising active safety systems is an autonomous emergency braking system (AEB). Both simulation and first implementation results showed that preventing all defined accident scenarios is not currently possible due to the limitations of the sensors and perception algorithms, which means that cyclists are still at risk. A possible solution to increase this AEB performance of the car is to add communication from the cyclist to the car. For that purpose Bosch, Shimano and TNO have formed a consortium to initiate a simulation study which is able to model the relevant accident scenarios, in-vehicle sensors, AEB logic, vehicle dynamic and communication in a realistic manner. In this study the benefit of several forms of communication, each with its own advantages and drawbacks, are added to current and future in-vehicle sensors. Two types of messages will be send: kinematic information and the prediction of the cyclist. The communication is either used as a sensor or as preparation, where in the latter the kinematic information is not used in the AEB logic. A benefit analysis showed that adding communication is most beneficial for in-vehicle systems with large classification- and internal delays. To achieve a high total benefit, a large field of view is also needed if the preparation strategy is used instead of the sensor strategy.
