A control module of a vehicle includes a driving diagnostic module and a hybrid control module. The drive diagnostic module determines a load energy of an accessory drive system of the vehicle and determines a slip ratio of a belt of the accessory drive system based on an engine speed and an engine speed. The hybrid control module determines a requested engine torque based on the load energy and / or the slip percentage. The control module controls an engine of the vehicle based on the requested engine torque.
