Abstract
An interlock control system linked to a digital key includes an alcohol interlock controller, which calculates a decomposition time period required to decompose blood alcohol of each driver using personal information of the driver, extracted by authenticating a digital key, when a blood alcohol concentration measured by an alcohol measuring sensor exceeds a reference value. The alcohol interlock controller then restricts ignition of a vehicle using the digital key for the decomposition time period. By calculating and providing the decomposition time period for restricting the ignition of the vehicle, based on the personal information and an actual alcohol clearance of the driver, predicted information on a time point for allowing the driver to drive the vehicle is provided to the driver. An interlock control method for the same is also provided.
