Abstract
A method for transmitting data in a sensor bus system and a sensor bus system. The sensor bus system includes an electronic controller, a plurality of sensors, and a twisted two-wire line between the electronic controller and the sensors, wherein the electronic controller is designed to supply electrical energy to the sensors via the twisted two-wire line, and the sensors are designed to transmit received information to the electronic controller in an I/Q-modulated manner via the twisted two-wire line.

1-12. (canceled).
A sensor bus system, comprising:
- an electronic controller;
- a plurality of sensors;
- and
- a twisted two-wire line between the electronic controller and the sensors, wherein the electronic controller configured to supply the sensors with electrical energy via the twisted two-wire line, and wherein the sensors are configured to transmit received information to the electronic controller in an I/Q-modulated manner the twisted two-wire line.
A method for data transmission in a sensor bus system, in which a plurality of sensors and an electronic controller are connected to one another in terms of information by a twisted two-wire line, the method comprising the following steps:
- supplying electrical energy to the sensors by the electronic controller via the twisted two-wire line;
- receiving information by the sensors;
- V/Q modulating the information in the sensors;
- and
- transmitting the I/Q-modulated information from the sensors to the electronic controller via the twisted two-wire line.
