Hybrid vehicle with internal combustion engine, exhaust after-treatment device (e.g. DPF), electrical heater to heat exhaust after-treatment device, electric machine operable as a generator to receive torque to slow the vehicle (i.e. regenerative braking) and output electrical power, and an energy storage device (i.e. battery). A prediction module outputs a parameter indicating a limitation of predicted energy supply to energy storage device, possibly during generator mode, and electrical power is distributed between battery and electrical heater on the basis of the anticipated energy supply. Predicted parameter may be an l2t limitation, may comprise a state of charge saturation of the energy storage device, and may be based on a projected route segment on which the vehicle is predicted to travel, the predicted route possibly being determined by means of a navigation system (e.g. GPS). A method of operation is also included. |
