Multi-function control knobs for multimedia systems of vehicles
First Claim
1. A multimedia system for a vehicle comprising:
- a processor; and
a multi-function control knob communicatively coupled to the processor, the multi-function control knob configured to provide control signals to the processor such that the multi-function control knoboperates in a volume control mode or a radio tune control mode;
switches between the volume control mode and the radio tune control mode in response to a double press of an area of the multi-function control knob in a direction in parallel with a central axis of the multi-function control knob, the double press being made to a same area on 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 volume control 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 radio tune control mode, wherein the first control signal and the second control signal are for controlling different multimedia operations;
sends a third control signal to the processor in response to a rotation of the multi-function control knob while operating in the volume control mode; and
sends a fourth control signal to the processor in response to a rotation of the multi-function control knob when operating in the radio tune control mode, wherein the third control signal and the fourth control signal are for controlling different multimedia operations.

Abstract
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.

14. A multimedia system for a vehicle comprising:
-
a processor; and a multi-function control knob communicatively coupled to the processor, the multi-function control knob configured to provide control signals to the processor such that the multi-function control knob operates in a volume control mode or a radio tune control mode; switches from the volume control mode to the radio tune control mode in response to a predetermined period of press and hold of the multi-function control knob in a direction in parallel with a central axis of the multi-function control knob when the multi-function control knob operates in the volume control mode; switches from the radio tune control mode to the volume control mode in response to the predetermined period of press and hold of the multi-function control knob in a direction in parallel with a central axis of the multi-function control knob when the multi-function control knob operates in the radio tune control mode; sends a first control signal to the processor in response to a single actuation of the multi-function control knob while operating in the volume control 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 radio tune control mode, wherein the first control signal and the second control signal are different signals for controlling different multimedia operations; sends a third control signal to the processor in response to rotation of the multi-function control knob while operating in the volume control mode; and sends a fourth control signal to the processor in response to rotation of the multi-function control knob while operating in the radio tune control mode, wherein the third control signal and the fourth control signal are different signals for controlling different multimedia operations. - View Dependent Claims (15)
