Problems solved by technology

When the failure record is not left in the ECU of the head unit, it is difficult to accurately distinguish whether the head unit or the camera unit is faulty
[0006] Secondly, even if the image input failure of the camera is only recorded in the ECU of the audio head unit, it is difficult to find the exact cause of the failure
That is, although the camera unit usually transmits images, when the image input failure of the camera is recorded in the ECU of the head unit, the failure of the screen of the head unit may appear slowly (for example, Audio-Video-Navigation (AVN) data are processed and create losses in the cable)
Therefore, it may be difficult to tell exactly whether the head unit or the rear camera is malfunctioning
[0007] In this way, since the malfunction of the camera unit and / or the head unit cannot be accurately determined, it is impossible to distinguish whether the head unit or the camera unit is malfunctioning, thereby consuming maintenance services and time unnecessarily

Abstract

Disclosed is a method of diagnosing a failure of a head unit and a camera unit for a vehicle including: supplying an operation voltage to the camera unit by the head unit and storing a voltage supply time, when a vehicle gear of the vehicle is located in a set gear stage; storing a signal reception time, when the head unit receives an image signal transmitted by the camera unit; diagnosing whether the camera unit is operating normally based on the voltage supply time and the signal reception time; and storing a breakdown diagnosis result by the head unit, when it is diagnosed that the camera unit breaks down.

Description

technical field [0001] The present disclosure generally relates to a method of diagnosing a malfunction of a head unit and a camera unit for a vehicle. More particularly, the present disclosure relates to a method of diagnosing a malfunction of a head unit and a camera unit for a vehicle, wherein the head unit and the camera unit communicate with each other to record causes of the malfunction of the head unit and the camera unit. Background technique [0002] Generally, a camera that photographs the environment behind the vehicle when the vehicle is running backward is installed at the rear of the vehicle, and a head unit including a display is installed on the central instrument panel (for example, center console) panel of the vehicle to display the environment through the rear camera. Acquired rear image. FYI, head unit refers to the control unit that collectively manages the telematics, radio, audio, video and navigation systems. [0003] A rear camera unit (hereinafter...
