Shift by wire system

A shift by wire system of a vehicle, the system comprising:

• a shift dial configured to shift gear positions comprising a stop gear, a reverse gear, and a forward gear;
• and
• an autonomous driving dial configured to control an autonomous driving mode of the vehicle, the autonomous driving dial being configured to:
• be covered by the shift dial based on the shift dial being disposed at the stop gear or the reverse gear, and be exposed from the shift dial based on the shift dial being disposed at the forward gear,
• wherein the system is configured to:
• activate the autonomous driving mode based on a rotation of the autonomous driving dial;
• and
• enable or disable a function of the autonomous driving mode based on a rotating direction of the autonomous driving dial, and
• wherein the autonomous driving dial comprises a lock button that is exposed to an outside of the autonomous driving dial, and
• wherein the shift dial is configured to:
• cause the vehicle to engage with a parking (P) gear based on the shift dial being moved to the stop gear, and
• cause the vehicle to switch from the P gear to a neutral (N) gear based on the lock button being manipulated in a state in which the shift dial is disposed at the stop gear.

A shift by wire system of a vehicle, the system comprising:

• a shift dial configured to shift gear positions comprising a stop gear, a reverse gear, and a forward gear;
• an autonomous driving dial configured to control an autonomous driving mode of the vehicle, the autonomous driving dial being configured to:
• be covered by the shift dial based on the shift dial being disposed at the stop gear or the reverse gear, and
• be exposed from the shift dial based on the shift dial being disposed at the forward gear;
• a main housing that is disposed at an interior structure of the vehicle and receives the shift dial, the shift dial being configured to rotate about a rotation axis and to move toward and away from the interior structure;
• a shift dial guide device configured to guide rotation of the shift dial along a rotating path of the shift dial and to guide movement of the shift dial along a moving path of the shift dial;
• and
• a shift dial return device configured to provide elastic force to the shift dial based on the shift dial moving linearly along the moving path,
• wherein the autonomous driving dial is surrounded by the shift dial and configured to rotate about the rotation axis,
• wherein the system further comprises:
• an autonomous driving dial guide device configured to guide rotation of the autonomous driving dial along a rotating path of the autonomous driving dial, and
• an autonomous driving dial return device configured to provide elastic force to the autonomous driving dial based on the autonomous driving dial rotating along the rotating path of the autonomous driving dial,
• wherein the autonomous driving dial guide device comprises a bullet disposed at the autonomous driving dial and configured to move in an axial direction of the main housing,
• wherein the main housing defines an autonomous driving dial groove at a bottom surface of the main housing, the autonomous driving dial groove extending in a circumferential direction of the main housing and being configured to receive the bullet, and
• wherein the bullet is configured to move along the autonomous driving dial groove to thereby guide the autonomous driving dial along the rotating path of the autonomous driving dial.
