The present disclosure relates to a system (3) for determining a position of a living being (9) in an interior of a vehicle (1). The system (3) comprises at least three components, each one of the at least three components being of a first component type or a second component type, one of the first or second component type being a transmitter (5a, 7a) and the other being a receiver (5b, 7b). Two of the components are of the first component type and one of the components is of the second component type. Each of the at least three components is adapted to transmit or receive a signal dependent on component type. The signal is adapted for determining a presence of the living being (9) and for determining a distance (d1, d2) between the living being (9) and each one of the components being of the first component type. The at least three components have active sectors, which are adapted to at least partly overlap within the interior of the vehicle (1). The components of the first component type are located at different positions, which positions are known relative to each other. The system (3) is adapted to determine the position of the living being (9) based on the determined distances (d1, d2).The disclosure further relates to a vehicle comprising such a system and a method for determining a position of a living being in an interior of a vehicle.
