1. A vehicular illumination presentation system comprising:
a first control system configured to control a vehicle interior illumination;
a second control system, independent from the first control system, configured to control a dimming unit located in a predetermined portion in a region surrounding a vehicle passenger compartment, the dimming unit being capable of adjusting a light transmittance;
a coordination control unit configured to coordinate an operation of the first control system and an operation of the second control system with each other; and
a coordination signal line connected to an output side of an illumination control unit of the first control system, wherein:
the illumination control unit outputs a signal indicating a current control state in the first control system to the coordination signal line;
a signal reflecting the control state of the illumination control unit is input to the second control system via the coordination signal line; and
the coordination control unit is configured to coordinate an operation of the second control system based on a signal input from the output of the illumination control unit and an instruction from a master control unit which is a control unit having a rank higher than that of the first and second control system.
