Abstract
A power system is disclosed. The power system may include one or more memories and a controller. The controller may determine an exhaust temperature of an engine associated with a continuously variable transmission or a hybrid transmission. The controller may determine a target increase to the exhaust temperature based on the exhaust temperature failing to satisfy a threshold. The controller may determine, based on a lookup table, a target increase to a torque output of the engine based on the target increase to the exhaust temperature. The controller may cause a parasitic torque of the engine to be increased based on the target increase to the torque output.
