Apparatus and method for diagnosing actuators in vehicle

摘要

An apparatus and a method for diagnosing actuators in a vehicle can improve accuracy and reliability of a failure diagnosis by allowing a diagnostic control apparatus in a vehicle to measure power data and implementing a fast diagnosis by reducing a separation time and a diagnosis time of a measurement apparatus.

1. An apparatus for diagnosing actuators in a vehicle, comprising:
a communication unit configured to communicate with an external terminal; a storage configured to store a diagnosable vehicle identifier; a diagnostic unit configured to transmit a response to whether a vehicle identifier included in a diagnosis request message received from the external terminal matches the vehicle identifier stored in the storage to the external terminal, receive a reference power value and a tolerance range of an actuator to be diagnosed to determine whether the actuator is out of order from the external terminal upon determination that the vehicle identifier included in the diagnosis request message matches the vehicle identifier stored in the storage, store the received reference power value and tolerance range in the storage, and generate a control signal for performing a measurement; and a measurement unit configured to drive the actuator to be diagnosed depending on the control signal to measure power consumption of a battery, wherein the diagnostic unit determines whether the actuator is out of order depending on whether a change of power consumption is within a tolerance range of the reference power value.
