Use of a bus line to transmit alternative signal coding
First Claim
1. A vehicle module for a vehicle, comprising:
- one or more sensors which are configured to record sensor data in an operating mode of the vehicle module and which are configured to adopt a large number of discrete states in an energy saving mode in order to provide a basic function of the vehicle module in the energy saving mode of the vehicle module;
an interface for a data line for transmitting the sensor data to a control device of the vehicle; and
an energy saving mode switch which is configured to connect the one or more sensors to the interface for the data line in the energy saving mode such that information relating to a state of the large number of discrete states is transmittable to the control device via the data line.

Abstract
A vehicle module for a vehicle includes one or more sensors, which are configured to record sensor data in an operating mode of the vehicle module, and are configured to adopt a plurality of discrete states in an energy saving mode in order to provide a basic function of the vehicle module in the energy saving mode of the vehicle module. The vehicle module further has an interface for a data line to transmit the sensor data to a control device of the vehicle. In addition, the vehicle module has an energy saving mode switch which is configured to connect the one or more sensors in the energy saving mode to the interface for the data line in such a way that information regarding a state of the plurality of discrete states can be transmitted to the control device via the data line.

16. A control device for a vehicle, wherein the control device is configured to execute processing to:
-
determine whether a vehicle module is in an operating mode or in an energy saving mode;
wherein the vehicle module comprises one or more sensors which are configured to transmit sensor data by way of a data line in the operating mode, and to transmit discrete state information by way of the data line in the energy saving mode;receive information from the vehicle module via the data line; and interpret the received information depending on whether the vehicle module is in the operating mode or in the energy saving mode.
