System and method for controlling a powertrain system of a vehicle

Abstract

The present disclosure relates to a computer system for controlling a powertrain system of a vehicle, the powertrain system including an internal combustion engine connectable to one or more drive wheels, the computer system comprising processing circuitry configured to selectively operate the powertrain system in a number of operational modes comprising at least a freewheeling mode (ES-FM), in which an output shaft of the engine is non-rotating and the engine is disconnected from the one or more drive wheels, wherein the processing circuitry is further configured to identify, in the freewheeling mode, a braking situation for the vehicle; responsive to the identified braking situation, determine to switch from a first clutch actuating engine restarting mode to a second clutch actuating engine restarting mode; and restart the engine by controlling a clutch according to the second clutch actuating engine restarting mode.

Dependencies are inferred from the claim text.
