Patent ID: 8547249

Claim:
A method for avoiding a collision between a vehicle and a non-motorized traffic participant comprising the following steps: a) a cell phone carried by the traffic participant sends a signal including positions of the traffic participant, b) a processing unit processes the signal including the positions of the traffic participant for a position history or evaluation history, c) the processing unit determines an estimation of a future position of the traffic participant on the basis of the position history or evaluation history, d) an acceleration of the traffic participant is sensed by an acceleration sensor of a cell phone carried by the traffic participant, wherein said acceleration sensor is also used for a manipulation of the operating state of said cell phone by moving said cell phone e) an action for avoiding a collision is automatically initiated in case that a distance of the future position of the traffic participant and said vehicle is smaller than a safety distance, wherein the safety distance depends on ea) the acceleration sensed by the acceleration sensor of the cell phone and eb) background information or context information related with the traffic participant, said background information or context information being selected from the group consisting of: background information including the weight of the traffic participant which has been stored in the cell phone and which is replaced, background information being learned throughout the use of the cell phone wherein the learned background information or context information does not base on an evaluation history of the last 10 seconds, and background information including an agenda of said traffic participant which is stored in the cell phone, wherein the safety distance is increased if the actual time is so close to a meeting time stored in said agenda that the remaining time is too short for reaching the location of the next date stored in the agenda of the cell phone.
