Abstract
A vehicle smart key system may include a smart key, and a smart key control device mounted on a vehicle that recognizes a position of the smart key through wireless communication with the smart key, activates vehicle functions in a stepwise manner based on the position of the smart key, and determines whether to assign a vehicle access right to the smart key.
Claims15
A vehicle smart key system comprising:
- a smart key in possession of a user of a vehicle;
- and
- a smart key control device mounted on the vehicle to recognize a position of the smart key through wireless communication with the smart key, i) to activate, based on the position of the smart key, vehicle functions stepwisely and ii) to determine when to assign a vehicle access right to the smart key,
- wherein the position of the smart key comprises a first zone and a second zone, both zones defined as distance regions within a predetermined radius range from the vehicle, such that the second zone is further from the first zone, and the first zone and the second zone are different, and
- wherein the smart key control device sets the vehicle functions in association with user profile information before the user rides in the vehicle, and instructs the smart key to output a warning for abnormality in a vehicle state, upon determining that the user gets off the vehicle without recognizing the abnormality in the vehicle state and is located at the second zone;
- such that when the user is approaching the vehicle leaving the second zone and enters the first zone, intensity of the warning changes so that the user recognizes the abnormality in the vehicle state based on the changed intensity.

A smart key control device mounted on a vehicle, the smart key control device comprising:
- a wireless communicator configured to perform wireless communication with a smart key in possession of a user of the vehicle;
- and
- a processor configured to recognize a position of the smart key through the wireless communication with the smart key, i) to activate, based on the position of the smart key, vehicle functions stepwisely and ii) to determine when to assign a vehicle access right to the smart key,
- wherein the position of the smart key comprises a first zone and a second zone, both zones defined as distance regions within a predetermined radius range from the vehicle, such that the second zone is further from the first zone, and the first zone and the second zone are different, and
- wherein the processor sets the vehicle functions in association with user profile information before the user rides in the vehicle, and instructs the smart key to output a warning for abnormality in a vehicle state, upon determining that the user gets off the vehicle without recognizing the abnormality in the vehicle state and is located at the second zone;
- such that when the user is approaching the vehicle leaving the second zone and enters the first zone, intensity of the warning changes so that the user recognizes the abnormality in the vehicle state based on the changed intensity.

A control method of a vehicle smart key system including a smart key in possession of a user of a vehicle and a smart key control device mounted on the vehicle, the control method comprising:
- a first step of recognizing, by the smart key control device, a position of the smart key;
- and
- a second step of i) activating, by the smart key control device, based on the position of the smart key, vehicle functions stepwisely, and ii) determining, by the smart key control device, when to assign a vehicle access right to the smart key,
- wherein the position of the smart key comprises a first zone and a second zone, both zones defined as distance regions within a predetermined radius range from the vehicle, such that the second zone is further from the first zone, and the first zone and the second zone are different, and
- wherein the smart key control device sets the vehicle functions in association with user profile information before the user rides in the vehicle, and instructs the smart key to output a warning for abnormality in a vehicle state, upon determining that the user gets off the vehicle without recognizing the abnormality in the vehicle state and is located at the second zone;
- such that when the user is approaching the vehicle leaving the second zone and enters the first zone, intensity of the warning changes so that the user recognizes the abnormality in the vehicle state based on the changed intensity.
