摘要： A torque limit section that applies limit to the torque instruction value of an electric motor such that the said switching elements temperature is restricted to no more than the element upper limiting temperature comprises: torque restriction means that finds a torque restriction value for restricting the torque of the electric motor in accordance with the said switching elements temperature; torque restriction mitigation means that finds a torque restriction mitigation value for mitigating the torque limit value in accordance with the integrated value of the deviation of the element upper limiting temperature and the switching elements temperature; a first subtractor (18) that finds a torque restriction value by subtracting the torque restriction mitigation value from the torque limit value; and a second subtractor (20) that finds a limited torque instruction value obtained by subtracting the torque limit value from the torque instruction value and outputs this to the gate generating section.
