Abstract
The present invention relates to a method for avoiding a collision between a vehicle and another traffic participant. According to the inventive method, a cell phone carried by the traffic participant sends a signal including a position of the traffic participant. A processing unit processes the signal including the position of the traffic participant for a position or evaluation history. The processing unit determines an estimation of a future position of the traffic participant on the basis of the position or evaluation history. The processing unit evaluates a likelihood of a collision between the vehicle and the traffic participant on the basis of the estimated future position of the traffic participant and an estimation of a future position of the vehicle. An acceleration of the traffic participant is sensed by an acceleration sensor of the cell phone. This acceleration sensor is multifunctionally used by using the sensor also for a manipulation of the operating state of the cell phone by moving the cell phone. An action for avoiding a collision is automatically initiated in case that a distance of the future position of the traffic participant and the vehicle is smaller than a safety distance. According to the invention, the safety distance depends on the acceleration which is sensed by the acceleration sensor of the cell phone.
