Abstract
A computer system controls an engine restart attempt of a vehicle, while the vehicle is moving. The computer system has processing circuitry to obtain data comprising real-time rotational speed level of any one of a powertrain shaft being mechanically connected to one or more wheels and the one or more wheels; control a controllable clutch to a torque transfer position, allowing the controllable clutch to change a torque transfer between an engine and the one or more wheels; determine, from the received data, a speed decrease of the rotational speed level; determine a time period of the speed decrease extension; determine that the determined speed decrease exceeds a predetermined threshold level; determine that the determined time period of the speed decrease extension is within a predetermined threshold time period; and determine to abort the restart engine attempt.
