Methods and systems for automatic detection of steering wheel control signals
DCFirst Claim
1. 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;
a signal processing unit adapted to auto-detect a control signal configuration of the first vehicle component, by;
(i) performing a first measurement on the at least one channel of the first vehicle component, and(ii) identifying the control signal configuration of the first vehicle component based on the first measurement; and
an output unit electrically connectable to at least one channel of a second vehicle component, the second vehicle component including an aftermarket entertainment component,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 first vehicle component.

Abstract
A method for automatically detecting a control signal configuration of a vehicle component includes making a connection to a channel of the component, performing an electrical measurement on the channel, and identifying a control signal configuration based upon the measurement. A method for sending control signals from one vehicle component to another includes making a connection on a channel of one component, making a connection to a channel of the other component, performing electrical measurements on the channels, identifying control signal configurations based upon the measurements, and configuring a control signal interface. A control signal interface includes an input unit, a signal processing unit, and an output unit. The input and output units each can connect to a channel of a vehicle component and perform an electrical measurement. The signal processing unit can determine control commands based upon control signals.
