Abstract
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.

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 hybrid-electric vehicle;
- determine an associated confidence value in dependence on the predicted destination;
- determine a route to be travelled by the hybrid-electric vehicle in dependence on the predicted destination;
- and
- output a signal to control an energy storage means of the hybrid-electric vehicle in dependence on the determined route and associated confidence value, such that the energy storage means has sufficient electrical energy to propel the hybrid-electric vehicle over a predetermined portion of the determined route in an electric-only mode,
- wherein outputting the signal to control the energy storage means of the hybrid-electric vehicle in dependence on the determined route and associated confidence value comprises outputting the signal to control the energy storage means of the hybrid-electric vehicle responsive to the associated confidence value being greater than a first limit and a ratio between a distance the hybrid-electric vehicle has travelled along the route and a distance to the predicted destination being greater than a second limit.
