The position and load measurement system comprises: - a passenger sensor (40) scanning the car interior and/ or the car door area (30); - a load signal pro­ cessing unit (35) connected to the passenger sensor for gen­ erating car load data, - an acceleration sensor (44) and/ or magnetometer (52), - a position signal processing unit (37) connected to the acceleration sensor and/ or magnetometer for generating car position data, and - a data link (46) for transmitting the output signals of the load signal processing unit and the position signal processing unit to an elevator control unit. The invention provides improved car load and car position data, particularly in connection with an overlay modernisation of an existing elevator system.
