A high-reliability controller for inverter is provided with a simple configuration. The controller for inverter includes a CPU 14 controlling energy of a vehicle, a CPU 15 controlling a power generation amount or an assist amount of a first motor 26, a CPU 16 controlling a power generation amount or an assist amount of a second motor 27, a regulator 8 generating power supplied to the CPUs 14, 15 and 16, a first inverter 23 controlled by the CPU 15, a second inverter 24 controlled by the CPU 16, and a communication line 17 that connects the CPUs 14 to 16. The first inverter 23 and the second inverter 24 are controlled in a cooperative or an independent manner.
