1. A control system for a vehicle, the control system comprising:
a controller comprising at least one processor and at least one non-transitory computer-readable medium including instructions;
a transformable knob configured to be manipulated by an operator between a first state and a second state and in electronic communication with the controller, wherein the manipulation consists of rotating the transformable knob or linearly moving the transformable knob, with the transformable knob comprising a body having a periphery wall arranged to flex between a first configuration corresponding to the first state and a second configuration corresponding to the second state, the transformable knob comprising:
an axle extending along an axis;
a body mounted to the axle and rotatable about the axis, with the body comprising a face plate and the periphery wall coupled to the face plate and extending around the axis, with the face plate and the periphery wall defining a cavity, and with the periphery wall arranged to flex relative to the axis;
a plurality of engagement arms disposed within the cavity and movable toward and away from the axis, with the plurality of engagement arms configured to selectively engage and flex the periphery wall between the first configuration and the second configuration; and
an actuator in engagement with the plurality of engagement arms and arranged to move between a first position and a second position, with movement of the actuator between the first and second positions facilitating corresponding movement of the plurality of engagement arms to flex the periphery wall between the first and second configurations, respectively; and
an output device in electronic communication with the controller and arranged to change between a first setting and a second setting based on the manipulation of the transformable knob;
wherein manipulation of the transformable knob by the operator from the first state to the second state transmits an input signal to the controller and facilitates flexing of the periphery wall from the first configuration to the second configuration to change an overall shape of the periphery wall of the transformable knob in response to manipulation of the transformable knob; and
wherein the controller is configured to receive the input signal and the processor is programmed to:
compare the input signal to the instructions in the at least one non-transitory computer-readable medium; and
transmit an output signal to the output device to change the output device from the first setting to the second setting based on the manipulation of the transformable knob.
