Methods and systems for providing accessory steering wheel controls
First Claim
1. A method for automatically detecting a configuration of a vehicle component, the method comprising:
- connecting a control signal interface to at least one channel of a first vehicle component, the first vehicle component being one of a steering wheel control component and a vehicle bus;
connecting the control signal interface to at least one channel of a second vehicle component, the second vehicle component being an aftermarket entertainment 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 a 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 a control signal configuration of the second vehicle component based on the second measurement; and
configuring the control signal interface based on 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.

Abstract
An aftermarket steering wheel control includes a housing that includes a user-operable switch and a control module. The control module is configured to determine whether the user-operable switch has been operated, generate a data frame corresponding to a control signal for operating a vehicle component, and transmit the data frame to a receiver of a control signal interface. Another aftermarket steering wheel control includes a housing with a user-operable switch and a circuit with an output line. The output line is connected to the switch and further connected to a control signal interface. Operation of the user-operable switch changes a resistance on the at least one output line, and the control signal interface is configured to convert the resistance to a control signal for operating a vehicle component.

7. A control signal interface comprising:
-
an input unit electrically connectable to at least one channel of a first vehicle component, the first vehicle component being one of a steering wheel control component and a vehicle bus, and the input unit being configured to (i) perform a first measurement on the at least one channel of the first vehicle component, and (ii) receive control signals from the first vehicle component; an output unit electrically connectable to at least one channel of a second vehicle component, the second vehicle component being an aftermarket entertainment component, and the output unit being configured to (i) perform a second measurement on the at least one channel of the second vehicle component, and (ii) transmit signals to the second vehicle component; and a signal processing unit connected to the input unit and the output unit, the signal processing unit configured to (i) identify a first control signal configuration of the first vehicle component based on the first measurement, (ii) identify a second control signal configuration of the second vehicle component based on the second measurement, and (iii) determine control commands based on the control signals received by the input unit and in accordance with the identified first control signal configuration, wherein the output unit is configured to transmit the signals to the second vehicle component based on the control commands determined by the signal processing unit and in accordance with the identified second control signal configuration, and wherein the input unit, in performing the first measurement, is configured to (i) determine, if the first vehicle component is a steering wheel control component, an electrical configuration of the first vehicle component, and (ii) determine, if the first vehicle component is a vehicle bus, a frame rate of the signal output by the first vehicle component. - View Dependent Claims (8, 9, 10)
