MULTI-FUNCTION CONTROL KNOBS FOR MULTIMEDIA SYSTEMS OF VEHICLES

摘要

A multimedia system for a vehicle is provided. The multimedia system includes a processor and a multi-function control knob communicatively coupled to the processor. The multi-function control knob is configured to provide control signals to the processor such that the multi-function control knob operates in a first mode or a second mode and switch between the first mode and the second mode in response to a double actuation of the multi-function control knob. The multi-function control knob sends a first control signal to the processor in response to a single actuation of the multi-function control knob while operating in the first mode, sends a second control signal to the processor in response to a single actuation of the multi-function control knob while operating in the second mode, sends a third control signal to the processor in response to a rotation of the multi-function control knob while operating in the first mode, and sends a fourth control signal to the processor in response to a rotation of the multi-function control knob while operating in the second mode.
