Abstract:
A method is described for determining a position of a user device in relation to a vehicle, the vehicle including first and second receivers. The method includes transmitting a positioning signal by the transmitter of the user device, receiving the positioning signal by the first receiver and by the second receiver arranged at a distance from the first receiver, in at least one of the first and second receivers, receiving and identifying a reflected positioning signal reflected at a ground surface before reaching the first and second receivers, performing time synchronization between the transmitter and the first and second receiver, determining a position of the user device in a three-dimensional coordinate system based on a time-of-flight of the positioning signal received in the first and second receivers and on a time-of-flight of at least one reflected positioning signal received by at least one of the first and second receivers.

Claim (Index 10):
The method according to  claim 1  wherein the position of the user device is determined analytically based on the relations:\n d _1=\u221a(( P _ x+D _ x )\u03022 +P _ y\u0302 2 +P _ z\u0302 2) \n d _2=\u221a(( P _ x\u2212D _ x )\u03022 +P _ y\u0302 2 +P _ z\u0302 2) \n d _ r 1=\u221a(( P _ x+D _ x )\u03022 +P _ y\u0302 2+( P _ z+D _ z )\u03022) \n d _ r 2=\u221a(( P _ x\u2212D _ x )\u03022 +P _ y\u0302 2+( P _ z+D _ z )\u03022) \n where d 1  is the distance from a first receiver position D 1  to the user device P, d 2  is distance from a second receiver position D 2  to the user device P, Px, Py and Pz are the coordinates of the user device P, Dz is the z-coordinate of the receiver positions D 1  and D 2  assuming that both receivers are located at the same distance from the ground plane which is located in z=0, and where x=0 is located at an equal distance from D 1  and D 2  such that the x-coordinates of D 1  and D 2  are \u2212Dx and Dx, and dr1 and dr2 is the travel distance of the reflected signal between the user device P and the respective receiver positions D 1  and D 2 .
