LIN network slave node control system, LIN network slave node and method

摘要

An LIN slave node control system, an LIN slave node and a method are provided. The system includes an electronic control part, which includes: an LIN signal detection, reception, and control module, a processing module connected to the LIN signal detection, reception, and control module and an LIN signal transmitting module connected to the processing module; the processing module generates, according to acquired analysis results, control signals for activating the LIN signal transmitting module, and transmits the control signals to the LIN signal detection, reception, and control module, or blocks LIN signal transmitting module and/or processing module control signals; the LIN signal detection, reception, and control module activates the processing module according to awake signals from an LIN bus, activates the LIN signal transmitting module according to the control signals from the processing module, or can block the LIN signal transmitting module and/or the processing module.
