Patent ID: 8165743

Claim:
A controller for an inverter comprising: an energy management processing unit that controls energy of a vehicle; a first motor control processing unit that controls a power generation amount or an assist amount of a first motor; a second motor control processing unit that controls a power generation amount or an assist amount of a second motor; a power supply unit that generates power supplied to the energy management processing unit, the first motor control processing unit and the second motor control processing unit; a first inverter that is controlled by the first motor control processing unit; a second inverter that is controlled by the second motor control processing unit; and a communication line that connects the energy management processing unit, the first motor control processing unit and the second motor control processing unit, wherein the first inverter and the second inverter are configured so as to be controlled in a cooperative or an independent manner, the controller further comprising: a first logic portion that generates a control signal of the first inverter in accordance with the first motor control processing unit; a second logic portion that generates a control signal of the second inverter in accordance with the second motor control processing unit; a power supply unit for logic portion that generates power used for the first logic portion and the second logic portion; a gate power supply unit that is used for a driving signal of a switching element that is provided in each of the first inverter and the second inverter, wherein if an abnormality is detected in the first motor control processing unit, the first motor control processing unit shuts off power supplied from the power supply unit for logic portion to the first logic portion, and the second motor control processing unit makes the second inverter continue an operation, and wherein if an abnormality is detected in the energy management processing unit, communication is conducted between the first motor control processing unit and the second motor control processing unit, so as to continue operations of the first inverter and the second inverter.
