METHOD AND SYSTEM FOR REPROGRAMMING

摘要

The system for reprogramming a plurality of control units includes a first control unit and a second control unit connected by one CAN bus, and a diagnosing unit. The diagnosing unit includes a first controller configured to reprogram the first control unit and a second controller configured to reprogram the second control unit. The diagnosing unit is configured to perform bidirectional reprogramming for the first control unit and the second control unit while sharing information between the first controller and the second controller.

1. A method of reprogramming a plurality of control units using a diagnosing unit including a first controller and a second controller, the method comprising:
receiving information on a first control unit by operating the first controller in a first control transmission mode for the first control unit; transmitting, when the first control transmission mode is finished, multi-reprogramming data to the first control unit on the basis of the information on the first control unit received in the first control transmission mode by operating the first controller in a first data transmission mode for the first control unit; receiving information on the second control unit by operating the second controller in a second control transmission mode for the second control unit while the first controller operates in the first data transmission mode; and transmitting, when the first controller finishes the first data transmission mode for the first control unit, multi-reprogramming data to the second control unit on the basis of the information on the second control unit received in the second control transmission mode by operating the second controller in a second data transmission mode for the second control unit.
