An electric motor control device (10) comprises: a target torque instruction unit (15) that gives instructions regarding a target torque to each of a right side control circuit (21R) and a left side control circuit (21L); and a failure occurrence identifier (18) that identifies if there is an occurrence of failure of the right side control circuit and the left side control circuit. If it is identified that there is an occurrence of failure of one of the two control circuits, the target torque instruction unit: gives instructions regarding a fail-safe torque lower than a normal target torque, as the target torque, to a failure-identified control circuit; and gives instructions regarding a failure time target torque lower than the normal target torque and higher than the fail-safe torque, to a normal control circuit.
电动机控制装置(10)包括:目标转矩指示部(15),该目标转矩指示部分别对右侧控制电路(21R)和左侧控制电路(21L)指示目标转矩;以及故障发生确定部(18),该故障发生确定部对右侧控制电路及左侧控制电路有无故障发生进行确定。在确定为两个控制电路中的一方有故障发生的情况下,目标转矩指示部针对故障确定控制电路指示比正常目标转矩低的故障安全防护用转矩作为目标转矩,并且针对正常控制电路指示比正常目标转矩低且比故障安全防护用转矩高的故障时目标转矩。
