Methods and systems for automatic detection of steering wheel control signals

A control signal interface comprising:

• an input unit electrically connectable to at least one channel of a first vehicle component, the first vehicle component including a steering wheel control component or a vehicle bus;
• an output unit electrically connectable to at least one channel of a second vehicle component, the second vehicle component including an aftermarket entertainment component;
• and
• a signal processing unit adapted to auto-detect a control signal configuration of the second vehicle component, by:
• (i) performing a measurement on the at least one channel of the second vehicle component, and
• (ii) identifying the control signal configuration of the second vehicle component based on the measurement,
• wherein the output unit is adapted to transmit control signals to the second vehicle component based on control signals received by the input unit and in accordance with the auto-detected control signal configuration of the second vehicle component.

A method for automatically detecting a configuration of a vehicle component, the method comprising:

• electrically connecting a control signal interface to at least one channel of a first vehicle component;
• electrically connecting the control signal interface to at least one channel of a second vehicle component;
• auto-detecting a control signal configuration of the first vehicle component, wherein said auto-detecting includes:
• (i) performing a first measurement on the at least one channel of the first vehicle component, the first measurement being performed by the control signal interface, and
• (ii) identifying the control signal configuration of the first vehicle component based on the first measurement;
• auto-detecting a control signal configuration of the second vehicle component, wherein said auto-detecting includes:
• (i) performing a second measurement on the at least one channel of the second vehicle component, the second measurement being performed by the control signal interface, and
• (ii) identifying the control signal configuration of the second vehicle component based on the second measurement;
• and
• configuring the control signal interface based upon at least one of the auto-detected control signal configuration of the first vehicle component and the auto-detected control signal configuration of the second vehicle component.
