Position determining system for multicar ropeless elevator system

An elevator system comprising:

• an elevator car configured to travel in a lane of an elevator shaft;
• a linear propulsion system configured to impart force to the elevator car, the linear propulsion system comprising:
• a first part mounted in the lane of the elevator shaft;
• and
• a second part mounted to the elevator car configured to co-act with the first part to impart movement to the elevator car;
• a plurality of car state sensors disposed within the lane and operable to determine a state space vector of the elevator car within the lane;
• a sensed element disposed on the elevator car, wherein each of the plurality of car state sensors is configured to detect the sensed element when the elevator car is in proximity to the respective car state sensor;
• and
• a control system operable to apply an electrical current to at least one of the first part and the second part,
• wherein the plurality of car state sensors are in communication with the control system and the linear propulsion system to provide state space vector data thereto.
