본 발명은 차량의 IPS 전류 검출 장치 및 그 방법에 관한 것으로, 하나의 펄스 내 듀티 사이클(Duty Cycle) 동안 샘플링된 복수의 IPS(Intelligent Power Switch) 전류(ISENSE)에 기초하여 최적의 샘플링 시간구간을 결정하고, 상기 결정된 샘플링 시간구간 내에서 IPS 전류(ISENSE)를 검출함으로써, 제조 공정에서 발생하는 각 IPS의 성능 편차에 관계없이 어떤 IPS가 장착되더라도 최적의 샘플링 시간에 IPS 전류를 검출할 수 있는 차량의 IPS 전류 검출 장치 및 그 방법을 제공하고자 한다. 이를 위하여, 본 발명은 차량의 IPS 전류 검출 장치에 있어서, IPS(Intelligent Power Switch) 전류를 감지하는 전류 감지부; 및 PWM(Pulse Width Modulation) 신호의 온 시간 구간에서 샘플링한 복수의 IPS 전류를 그룹화한 후 각 그룹 내 IPS 전류에 기초하여 샘플링 시간구간을 결정하고, 상기 결정된 샘플링 시간구간에서 IPS 전류를 검출하는 제어부를 포함한다.

    The present invention relates to an apparatus for detecting an intelligent power switch (IPS) current of a vehicle and a method thereof. An objective of the present invention is to provide an apparatus for detecting an IPS current of a vehicle and a method thereof which determine an optimal sampling time zone based on a plurality of IPS currents (I_SENSE) sampled during a duty cycle in a single pulse, and detect an IPS current (I_SENSE) in the determined sampling time zone to detect an IPS current at an optimal sampling time no matter which IPS is mounted regardless of performance deviations of IPSs created in a manufacturing process. To achieve the objective, the apparatus for detecting an IPS current of a vehicle comprises: a current sensing unit to sense an IPS current; and a control unit to determine a sampling time zone based on an IPS current in each group after grouping a plurality of IPS currents sampled in an on time zone of a pulse width modulation (PWM) signal, and detect an IPS current in the determined sampling time zone.
