A vehicle driveline and a method for synchronizing a flywheel and the vehicle driveline are provided. The vehicle driveline includes a power source, a primary clutch drivingly engaged with the power source, a primary transmission drivingly engaged with the primary clutch, a secondary transmission drivingly engaged with one of a portion of the primary clutch and an input of the primary transmission, a controller in communication with the secondary transmission, and a flywheel drivingly engaged with the secondary transmission. The vehicle driveline facilitates a transfer of energy to and from the flywheel based on at least one of a state of charge of the flywheel, a power requirement of the vehicle driveline, and a state of operation of the power source.

A control system for a hybrid-electric vehicle, the control system comprising one or more controllers, wherein the control system is configured to: determine a predicted destination for the vehicle; determine an associated confidence value in dependence on the predicted destination; determine a route to be travelled by the vehicle in dependence on the predicted destination; and output a signal to control an energy storage means of the vehicle in dependence on the determined route and associated confidence value, such that the vehicle may travel a portion of the determined route in an electric-only mode.
