PROBLEM TO BE SOLVED: To selectively stop drive of only an injector whose injection signal wire is short-circuited for power. SOLUTION: When an injection command for one of two injectors belonging to the same group and an injection stop command for the other injector are input, an injector determination circuit 46 outputs an injector determination signal that indicates the injector receiving the injection command. When an injection signal IJtA causes the power short-circuit, a drive signal generation circuit 47 outputs a drive signal A at a level L (current interruption), and outputs a drive signal B in accordance with an injection signal IJtB, in regard to the injector B.
