Disclosed is a turbocharger control device of a vehicle and a method of estimating base boost pressure using the same. The turbocharger control device of a vehicle includes a status information collection unit for collecting real-time status information according to an operation of a turbocharger when a vehicle is operated from various types of sensors, and a control unit for precisely estimating a base boost pressure by excluding a turbocharger boost pressure from a current boost pressure through a turbine power function and a compressor power function based on a physical model based on the collected status information.

A method for controlling starting of a mild hybrid vehicle includes receiving a starting-request signal and in response, increasing a rotation speed of the engine by driving the MHSG by electricity supplied from a battery. Status data of the mild hybrid vehicle for controlling starting of the engine is monitored to obtain an engine rotation speed from the status data and determine an injection-starting rotation speed based on the status data. When the engine rotation speed is greater than the injection-starting rotation speed, fuel injection of the engine is started.
