Embodiment Construction

[0021] Embodiments of the present invention will be described in detail with reference to the following drawings so that those skilled in the art to which the present invention pertains can easily implement. However, the present invention can be realized in various forms, and is not limited to the embodiments described here. In addition, in order to clarify the present invention, parts irrelevant to the description are omitted from the drawings, and similar reference numerals are added to similar parts throughout the entire specification.

[0022] In the entire specification, when some parts "include" certain constituent elements, it means that other constituent elements may be included, rather than other constituent elements excluded, unless otherwise specifically objected to. In addition, terms such as "... part", "... device" and "module" described in the specification mean a unit that handles at least one function or operation, and this can be implemented as hardware or so...

Abstract

The invention discloses a LIN communication system for a vehicle and a method for driving a slave module. The conventional master instruction is used when a master module deletes the specific action of the slave module. A plurality of IDs are given to each slave module, and when IDs are respectively called, the relative slave module conducts relative function defined in advance, and thereby communication time required by the transmission of the master instruction can be shortened, and the whole communication time can be shortened.

Description

technical field [0001] The present invention relates to a LIN (Local Interconnect Network) communication system for a vehicle and an operation method of a slave module using the system, and relates to shortening the LIN communication time so that the master module (master module) can quickly receive the response transmitted from the slave module (slave module) The signal vehicle LIN communication system and the operation method of the slave module in this system. Background technique [0002] In network communication for vehicles, in order to effectively control electromechanical nodes such as parking assist sensors, drivers, and other modules on a distributed network, LIN network communication methods, which are serial communication methods, are widely used. [0003] In LIN communication, there is a master module that requests data, and multiple slave modules that process data in response to data requests from the master module and respond. [0004] figure 1 It is a scree...
