Abstract

The present disclosure provides a system and a method for inspecting an assembled condition of an alternator capable of inspecting a driving condition using a smart box monitoring sensor data received from an ECU of a vehicle and then determining whether the assembled condition of the alternator is bad. A system for inspecting an assembled condition of an alternator includes: a smart box configured to receive driving data of a vehicle from an ECU and determine whether the assembled condition of the alternator is bad based on the driving data of the vehicle; and a server configured to receive result data depending on whether the assembled condition of the alternator is bad from the smart box.

Claims

1. A system for inspecting a condition of an alternator, comprising:

a smart box configured to receive driving data of a vehicle from an electronic control unit (ECU) and determine the condition of the alternator based on the driving data of the vehicle; and

a server configured to receive result data, from the smart box, depending on the condition of the alternator.

2. The system according to claim 1, wherein the ECU transmits and receives a battery charging signal to and from the alternator.

3. The system according to claim 1, wherein the driving data include a speed of the vehicle, a throttle position sensor, a driving distance, a target duty, an FR duty, and a difference value between a targeted voltage and an actual voltage of a battery.

4. The system according to claim 1, wherein the driving data is, transmitted and received between the smart box and the server through a radio repeater by using Bluetooth.

5. The system according to claim 1, further comprising:

an inspection status board connected to the server.

6. The system according to claim 1, wherein the server stores the result data depending on the condition of the alternator and transmits the result data depending on the condition of the alternator to a research institute.

7. A method for inspecting a condition of an alternator, comprising:

receiving, by a smart box, driving data of a vehicle from an electronic control unit (ECU);

determining the condition of the alternator based on the driving data of the vehicle which are received by the smart box; and

transmitting, by the smart box, result data depending on the condition of the alternator to a server.

8. The method according to claim 7, wherein the driving data include a speed of the vehicle, a throttle position sensor, a driving distance, a target duty, an FR duty, and a difference value between a targeted voltage and an actual voltage of a battery.

9. The method according to claim 7, wherein the determining, by the smart box, the condition of the alternator includes:

monitoring a preset target duty of the driving data, an FR duty, and a difference value between a targeted voltage and an actual voltage of a battery; and

determining the condition of the alternator at least based on the driving data received from the ECU.

10. The method according to claim 9, wherein the determining the condition of the alternator further includes:

outputting, by the smart box, a warning sound depending on the condition of the alternator; and

turning on a red LED after the warning sound is output.

11. The method according to claim 9, wherein the determining the condition of the alternator further includes:

keeping, by the smart box, a green LED continuously turned on without outputting a warning sound if it is determined that the condition of the alternator is good.

12. The method according to claim 7, further comprising:

after the transmitting of the result data depending on the condition of the alternator to the server,

storing, by the server, the condition of the alternator; and

displaying the condition of the alternator on an inspection status board or transmitting the condition of the alternator to a research institute.
