Method and configuration for transmitting data in a motor vehicle
First Claim
Patent Images
1. A method for transmitting data in a motor vehicle having a transmitter and a receiver, which comprises the steps of:
- splitting a signal which is to be transmitted, into a constant part and a variable part; and
combining a partial value of the constant part with the variable part and transmitting a result signal to the receiver.

Abstract
A method for extracting a constant part and a variable part from a data signal that is determined. The values that are extracted in this way are transmitted with different timing over a transmission link that is present. Depending on the bandwidth of the composite signal, various methods can be applied for transmitting relatively low bandwidth signals with possibly higher resolution.

9. A configuration for transmitting data in a motor vehicle, comprising:
-
a transmitter having extraction means for extracting a constant part from a signal to be transmitted formed of a constant part and a variable part, a subtracting element having an output for subtracting the constant part from the signal to be transmitted and said subtracting element connected to said extraction means, a divider having an output and connected downstream of said extraction means and dividing the constant part by N, and an adding element connected to said output of said divider and to said output of said subtracting element, said adding element having an output where a data-reduced signal for transmission can be tapped; and
a receiver for communicating with said transmitter. - View Dependent Claims (10, 11, 12, 13, 14)
