Method for providing control system of vehicle, electric control unit and headlight control system

Abstract

A method of preparing a vehicle control system having an intended function by using at least two ECUs is provided. One of the at least two ECUs is used for adaptively incorporating a modified portion of the intended function of the vehicle control system through re-design in a short period, while the rest of the ECUs in the vehicle control system sustain and support an unchanging portion of the intended function of the vehicle control system.

What is claimed is: 
     
         1 . A sensor module connected to a separate vehicle compartment via an in-vehicle communication line, controlling a headlight unit of the vehicle based on whether an oncoming vehicle is exist ahead of the vehicle, and the sensor module comprising:
 a sensor that detects whether there is the oncoming vehicle;   an electric control unit connected to the sensor,   wherein,   the electric control unit receives an switch operation state from the separate vehicle compartment, and   the electric control unit controls an automatic angle of a light beam of the headlight unit based on the switch operating state when the sensor detects the oncoming vehicle.   
     
     
         2 . The sensor module of  claim 1 , wherein a headlight controlling signal of the sensor module has a priority to a headlight controlling signal of the separate vehicle compartment when the separate vehicle compartment directly controls the headlight unit. 
     
     
         3 . A sensor module connected to a separate vehicle compartment via an in-vehicle communication line, controlling a headlight unit of the vehicle based on whether an oncoming vehicle is exist ahead of the vehicle, and the sensor module comprising:
 a sensor that detects whether there is the oncoming vehicle;   an electric control unit connected to the sensor via the in-vehicle communication line,   wherein,   the electric control unit receives an switch operation state from the separate vehicle compartment, and   the electric control unit controls an automatic light beam of the headlight unit based on the switch operating state when the sensor detects the oncoming vehicle.   
     
     
         4 . A method for controlling a headlight unit by a sensor module comprising:
 a step for receiving switch operation state by the sensor module from a separate vehicle compartment via an in-vehicle communication line;   a step for detecting an oncoming vehicle ahead;   a step for controlling an automatic angle of a light beam of the headlight unit based on the switch operating state and whether if there is an oncoming vehicle ahead.
