An electric motor control device includes a target torque setting unit setting target torque for each of a right-side control circuit and a left-side control circuit, and a failure occurrence determination unit determining whether there is a failure occurrence in at least one of the two control circuits. The target torque setting unit sets, in response to there being a failure occurrence in a failure control circuit that is one of the two control circuits and there being a no failure occurrence in a normal control circuit that is the other of the two control circuits, fail-safe torque which is lower than a normal value of the target torque as the target torque for the failure control circuit, and sets failure-time target torque which is lower than the normal value of the target torque and being higher than the fail-safe torque as the target torque for the normal control circuit.
