Device and method for transmitting vehicle position data
First Claim
1. A position detection and transmission device (100) for a vehicle (200), the position detection and transmission device (100) comprising:
- a position detection unit (110) configured to detect a position of the vehicle;
a control unit (120) configured to receive position data from the position detection unit; and
a transmission unit (130) coupled to the control unit and configured to transmit the position data processed by the control unit (120) to a receiving unit,wherein the position data received by the control unit comprises a multitude of position values, andwhereinthe control unit (120) is further configured to determine a difference between an initial position value from among the multitude of position values and each one of subsequent position values from among the multitude of position values, respectively, and to provide transmission information representative of the multitude of position values, the transmission information comprising an absolute value representative of the initial position value and a plurality of delta values each representative of the respective difference between the initial position value and each one of the subsequent position values, the absolute value being represented by data of a first size and each delta value being represented by data of a second size, the first size being larger than the second size, anddata of the first size representative of the absolute value and plural units of data of the second size, each representative of a respective delta value, are provided to the transmission unit (130) for transmission to the receiving unit.

Abstract
A position detection and transmission device for a vehicle includes a position detection unit that detects a position of the vehicle, a control unit that receives position data from the position detection unit, and a transmission unit, coupled to the control unit, that transmits the position data processed by the control unit to a receiving unit. The control unit determines a difference between an initial position value and each one of the subsequent position values, respectively, and provides the initial position value and the respective difference between the initial position value and each one of the subsequent position values to the transmission unit for transmission to the receiving unit.

8. A method for detecting and transmitting a position of a vehicle, the method comprising:
-
detecting (S1) a first position of a vehicle; determining (S2) a first position value corresponding to the first position of the vehicle; transmitting (S3) an absolute value representative of the first position value to a receiving unit, the absolute value being represented by data of a first size; detecting (S4) a second position of the vehicle; determining (S5) a second position value corresponding to the second position of the vehicle; determining (S6) a difference between the second position value and the first position value; and transmitting (S7) a delta value representative of the difference between the second position value and the first position value to the receiving unit, the delta value being represented by data of a second size, the second size being smaller than the first size. - View Dependent Claims (9, 10, 11, 12, 13)
