Abstract
A hybrid drive system includes an engine; at least one rotating electric machine, wherein the engine and the at least one rotating electric machine are capable of driving a vehicle; and a controller. The controller starts a load limit control that limits a load exerted to the rotating electric machine when a temperature of the rotating electric machine exceeds a load limit start temperature; detects a loading state or a towing state of the vehicle; and determines the load limit start temperature based on the loading state or the towing state detected.
