PURPOSE:To simplify a hardware part, and also to prevent a malfunction of a load by detecting as an abnormality when >=2 operation commands which cannot occur simultaneously are generated, and initializing a control program by a CPU. CONSTITUTION:When operation commands which cannot occur simultaneously, such as a right-turn command signal Sa and a left-turn command signal are generated, a CPU15 holds loads (a turn signal lamp 10 for right turn and a turn signal lamp 11 for left turn) corresponding to said operation commands, in a driving stop state. Accordingly, such a malfunction as both the turn signal lamps 10, 11 are turned on simultaneously, etc. can be prevented by providing such an abnormality detection program for turn signal before a program related to a control of the turn signal lamp 10 for right turn and the turn signal lamp 11 for left turn. |
