Abstract: A system for the generation of call advance data for an elevator control, which system is going to be installed in an elevator car moving in an elevator shaft and includes at least one acceleration sensor outputting current acceleration data and/or magnetometer outputting a magnetic flux signal which includes current magnetic flux data at the current position of the elevator car, which acceleration sensor and/or magnetometer is mounted in connection with the elevator car; a velocity calculating unit which calculates from the current acceleration/magnetic flux data current car velocity data; a position calculating unit which calculates from the current acceleration/magnetic flux data and/or from the current car velocity data current car position data; and a call advance processing unit which calculates from the current car velocity data and the current car position data call advance data which designates the time until which the car is able to stop at the next approaching floor in travelling direction, which call advance data is transmitted to a call allocation unit of an elevator control. Call advance data is provided in an easy manner without using existing car position detection devices of an existing elevator to be modernized.
