Abstract
A computer system for controls a powertrain system of a vehicle. The computer system has processing circuitry to operate the powertrain system in a freewheeling mode, in which an output shaft of an engine is non-rotating, and the engine is disconnected from one or more drive wheels. The processing circuitry determines an opportunity for the freewheeling mode by predicting a feasibility of restarting the engine along an intended route by using a controllable clutch. Predicting the feasibility of restarting the engine by using the controllable clutch includes determining fulfillment of any one of a first restarting condition and a second restarting condition. The powertrain system is controlled into the freewheeling mode upon the fulfillment of any one of the first restarting condition and the second restarting condition.
