Abstract:
1. A control apparatus for controlling each of a power converter and a cooling apparatus, the power converter comprising a plurality of switching elements and being electrically connected to a rotary machine, the rotary machine operating as a drive motor of a vehicle when supplied with electrical power from the power converter, the cooling apparatus operating to circulate a coolant fluid via a circulation path extending through the power converter and the rotary machine, and configured to acquire a temperature value of the switching elements, wherein the control apparatus is configured to acquire a temperature value of the coolant fluid, and comprises processing circuitry configured for: executing a first comparison operation, to compare the acquired temperature value of the coolant fluid with a first temperature threshold; executing a second comparison operation, to compare the acquired temperature of the switching elements with a second temperature threshold, the second temperature threshold being higher than the first temperature threshold and no higher than a maximum allowable temperature of the switching elements; and selectively executing processing for limiting a maximum value of electrical power supplied to the rotary machine from the power converter and processing for releasing the limiting, the selection being performed based upon results of the first comparison operation and the second comparison operation.
