A vehicular control system operated in VLC spectrum is envisaged in this work which is control by optical monochromatic filters. Overall six numbers of monochromatic optical filters are designed by the help PWE simulation method by considering silicon grating structure (Si and SiO) as background semiconductor material to control the direction of the vehicular system. Further, Matlab Simulink is implemented to realize the different direction with the degree of angular rotation while moving in left and right direction. In the simulation process, Arduino board is used to receive the control signals from the filters through the photo detectors and then according to the program stored in the memory, the outputs are actuated to drive the vehicular system corresponding to each combination of the inputs.
