1 is a configuration diagram of a system for checking built-in automotive parts according to an embodiment of the present invention, FIG. 2 is a detailed configuration diagram of the engine momentum detection means of FIG. 1, and FIG. 6 is an embodiment of the present invention. This is a state diagram of the system for checking the timing of built-in automotive parts.

1, 2 and 6, the built-in automotive parts inspection time measurement system of the present invention is embedded in the instrument panel of the vehicle, when the engine 10 is driven, transmitted from the engine 10 to the cigar jack 20 Engine momentum detection means 100 for calculating the engine momentum by detecting the electrical signal is provided.

The engine momentum detection module 123 generates an engine driving signal that is a signal having a voltage pulse width by a voltage difference compared with the amplified signal of a predetermined voltage and a reference signal having a constant voltage level.

The control unit 110 accumulates the number of pulses of the engine driving signal, and calculates the cumulative traveling distance from the accumulated number of pulses by using the reference unit pulse number stored in advance in the storage unit 130.

The reference unit pulse number is a value corresponding to the number of pulses per kilometer. For example, if the reference unit pulse number is 10 pulses and the accumulated pulse number is 50,000 pulses, the calculated running distance is 5000 km.

In addition, when the cumulative driving distance is calculated, the controller 110 determines an inspection time for each part by using the cumulative driving distance and a pre-stored driving distance setting value for each part.

In particular, the mileage setting value for each part can be updated even after storage, and it is desirable to be able to adjust the inspection time or replacement time for each part.

The screen display unit 150 receives previously generated inspection time information under the control of the controller 110 and displays the inspection time information for each component on the screen.

When the alarm notification unit 160 determines that the corresponding part is the inspection time according to the determination of the inspection time for each part from the control unit 110, the alarm notification unit 160 operates the alarm lamp 161 under the control of the control unit 110 or the alarm speaker ( 162).

As illustrated in FIG. 1, the wireless communication unit 170 is provided to enable wireless communication with the portable terminal 200, and may transmit inspection time information to the portable terminal 200 by wireless communication.
