WIPO Patent Application WO/2017/208787
Kind Code:
A1
Abstract:
This lamp control device controls, in conjunction with an operation of a display switch that is provided to a vehicle, the flashing of a lamp that is provided to the vehicle. The lamp control device comprises: an output unit that, on the basis of a flash command signal directing the flash timing of the lamp, outputs a flash signal to the lamp from an output terminal for driving, said flash signal causing the lamp to flash; an input unit that outputs a state signal of a first logic if a signal level from the output terminal for driving is a first level, said state signal indicating that the state of the display switch is an on state, and outputs a state signal of a second logic if the signal level is a second level that is different from the first level, said state signal indicating that the state of the display switch is an off state; a control unit that outputs the flash command signal to the output unit if the logic of the state signal outputted from the input unit is the first logic; and a self-maintenance unit that, if the lamp is in a flashing state, maintains the logic of the state signal on the basis of the logic of the flash command signal.
