Recently, IT industry is in fast growth. And very much IT convenient device for life is developed. This has been emerged as core technology in automotive industries. And some of these products have unintended malfunctions. because of the environment of driving, the device can cause a driver’s momentary carelessness. And this carelessness can cause a traffic accident. Wierwille & Tijerina(1996) studied about car crash in North Carolina. In study, a driver’s carelessness accident is 55.5% of 2,819 accidents. This result means accident can be happen by ordinary action like changing channel of radio. So, many people are studing a simple control method. This paper suggests this control method using IR sensor. The method can simply control increased devices. And It can decrease carelessness action for safe drive. Used IR sensor gets 3 IR LED data. The 3 IR LED is used to recognize hand motion like directions of right, left, up and down. These motions are used to control devices like radio, MP3, navigation. This is more safer control than before because this needs not to find the controller’s location exactly.

Recently, Software design is developed by regular procedures. But these regular procedures are difficult to fulfill in the field. The field can be changed the project in coding or test step by the change of requirements or the occurrence of a problem. Model-Based Design is proposed this problem solution. Model-Based Design is recycled in various stages of design information. So, the design method can be modeling and simulation before to the real hardware. This Model-Based Design’s typical program is the MATLAB. The interior lamp of automotive is developed very much. Recent interior lamp is not simple. The interior lamp functions are only lamp ON or OFF function but also CAN communication, Data processing, Input processing, analysis and results output function. This function is working used MCU(microcontroller unit). Also center fascia is have very many function. So, this place can’t add function. For that reason, interior lamp is including something of user indirect control like bluetooth module. Reliability is important in interior lamp because of this complicated function. And this reliability of products raises the commercial value. So this paper is suggested development method of interior lamp system using MATLAB.
