Abstract: PURPOSE: A vane control method of a turbo charger is provided to prevent the rotation speed of a turbine and the boost pressure from being excessively increased during repetitively accelerated driving. CONSTITUTION: A vane control method of a turbocharger is as follows. An acceleration counter and a timer are initialized, and the timer is operated. A value of the acceleration counter is increased in case both of the degree of opening of an accelerator and a differential value of the degree of opening of the accelerator pedal are equal to predetermined values. Repetitive acceleration is determined when the timer shows that the time is less than a fixed time, and when the value of the acceleration counter is more than a predetermined acceleration value. A vane control value is compensated to open a vane as much as the predetermined value in case of repetitive acceleration.

Abstract: PURPOSE: A controlling method of a target RPM(Revolution Per Minute) of an engine is provided to obtain improved fuel efficiency and cost-cutting effect by controlling the fuel injection timing and rate, and to reduce unnecessary fuel injection. CONSTITUTION: A controlling method of a target RPM of an engine is as follows. A control signal is input to change the target RPM of an engine during driving of a vehicle. Whether a driver has an intention of stopping the vehicle or not is judged from the input control signal. The fuel injection timing and rate is controlled by changing the target RPM in case the driver has an intentions of stopping the vehicle.
