PURPOSE: A method for detecting the combustion phase of an engine is provided to efficiently estimate heat production in early stage of combustion and detect a combustion phase in real time, thereby securing exhaust gas reduction and stable combustion. CONSTITUTION: A method for detecting the combustion phase of an engine detects a combustion phase by using a special spot of DRdV and a following equation(5), wherein Pdiff is the difference between combustion pressure and motoring pressure and V is the capacity of a combustor. The special spot for detecting the combustion phase located between 0% and 50% of DRdV and between 0° and 20° of crank angle.

PURPOSE: A parking assistant system is provided to reduce cost, and detect a sensor and a mounting position of a sensor by precluding an additional sensor unit driving a sensor. CONSTITUTION: A parking assistant system comprises a plurality of digital sensors(100) and a controller(200). The digital sensor monitors the rear of a vehicle, installed in the center part and a corner part of a vehicle. The control part determines whether ID of the digital sensor is set up. In case it is determined that ID is not set up at the digital sensor, the control part compares the indirect signal measured from the digital sensor and sets up ID of a sensor based on the position of the detected sensor. In case ID of any sensor of the sensors is not set up at the digital sensor, the control part checks the position of the sensor with ID set in turn and grants ID of sensor with no ID set. In case the indirect signal of a sensor is greater than the predetermined reference signal, the control part determines that the sensor is located in the rear center. In case the indirect signal is smaller than the predetermined reference signal, the control part determines that the sensor is located in the corner part.
