Abstract:
A reconfigurable steering wheel control switch system for a motor vehicle comprises a first module, a second module, a plurality of switches mounted on a steering wheel, and a multiplexer. The multiplexer is in communication with the first module, with the second module, and with the plurality of switches. The multiplexer communicates with the first module and with the second module to determine which one of these modules is currently active. When the first module is active, the multiplexer assigns a first configuration of functions to the plurality of switches. These functions are used to control the first module from the steering wheel. When the second module is active, the multiplexer assigns a second configuration of functions to the plurality of switches. These functions are used to control the second module from the steering wheel.
