Abstract
A rotary switch device for a vehicle includes a rotary dial module including a plurality of sensors, a material configured to react to a magnetic force, and a base module that generates a magnetic force greater than or equal to a threshold value to enable the rotary dial module to be attached to the base module and transmits detection results from the plurality of sensors included in the rotary dial module to an electronic device inside the vehicle when the rotary dial module is attached to the base module.
Claims12
A rotary switch device for a vehicle, the rotary switch device comprising:
- a rotary dial module including a plurality of sensors and a material configured to react to a magnetic force;
- and
- a base module configured to generate a magnetic force greater than or equal to a threshold value to enable the rotary dial module to be attached to the base module and transmit detection results from the plurality of sensors included in the rotary dial module to an electronic device inside the vehicle when the rotary dial module is attached to the base module;
- wherein the base module comprises a magnetic coil configured to generate the magnetic force according to a received current;
- and
- wherein the rotary dial module is detached from the base module when the magnetic force generated by the magnetic coil is less than the threshold value.
A method for operating a rotary switch device for a vehicle, the method comprising:
- an attachment force setting step of generating and maintaining a magnetic force greater than or equal to a threshold value, by providing a current to a magnetic coil, when a rotary dial module is attached to an upper portion of a base module;
- an attachment maintenance determination step of determining whether the vehicle is in an autonomous driving mode or a detachment condition is satisfied;
- a sensor activation step of activating sensors included in the rotary dial module and receiving detection results of the activated sensors, when it is determined in the attachment maintenance determination step that the vehicle is in an autonomous driving mode or the detachment condition is satisfied;
- a detachment situation determination step of determining a detachment situation based on the detection results in the sensor activation step;
- and
- a first attachment force change step of changing the magnetic force to be less than the threshold value, by controlling the current to the magnetic coil of the base module, when the detachment situation is determined in the detachment situation determination step.
