System and method for determining a position of a living being in a vehicle
First Claim
1. A system for determining a position of a living being in an interior of a vehicle, said system comprising:
- at least three components, each one of said at least three components being of a first component type or a second component type, one of said first or second component type being a transmitter and the other being a receiver, two of the components being of said first component type and one of the components being of said second component type, each of said at least three components being adapted to transmit or receive a signal dependent on component type, said signal for use in determining a presence of said living being and for determining a distance (d1, d2) between said living being and each one of said components being of said first component type;
wherein said at least three components have active sectors, at least two of which are adapted to at least partly overlap within said interior of said vehicle;
wherein said components of said first component type are adapted to be located at different positions, which positions are known relative to each other; and
wherein said system is adapted to determine said position of said living being based on said determined distances (d1, d2).

Abstract
A system for determining a position of a living being in a vehicle interior includes at least three components, each component of a first type or a second type, one of the first or second type being a transmitter and the other a receiver. Two components are of the first type and one component is of the second type. Each component is adapted to transmit or receive a signal dependent on type. The signal is adapted for determining a presence of the living being and for determining a distance (d1, d2) between the living being and each component of the first type. The components have active sectors adapted to at least partly overlap within the vehicle interior. The components of the first type are located at different positions known relative to each other. The system is adapted to determine the living being position based on the determined distances (d1, d2).

9. A method for determining a position of a living being in an interior of a vehicle using a transmitter, a receiver and a controller, said method comprising:
-
a) transmitting a first signal into said interior of said vehicle; b) receiving a first reflected signal from a first object; c) determining whether or not said first object is a living being based on said first reflected signal; d) associating said first object with a first distance; e) receiving a second reflected signal from a second object, said second reflected signal at least partly following another signal path than said first reflected signal; f) determining whether or not said second object is a living being based on said second reflected signal; g) associating said second object with a second distance; h) comparing said second reflected signal to said first reflected signal; i) from said comparison, determining whether said living being associated with said second reflected signal is the same as said living being associated with said first reflected signal; and j) if the same, using said first and second distances for determining the position of said living being. - View Dependent Claims (10, 11, 12, 13, 14, 15)
