Driver break preparation system for a hybrid vehicle
First Claim
1. A control system for use in a commercial hybrid electric vehicle having an internal combustion engine combined with a motor-generator and an electrical energy storage unit, the control system comprising:
- a control unit configured to control the internal combustion engine and the motor-generator to actively charge the electrical energy storage unit in accordance with a determination that a predicted state of charge of the electrical energy storage unit during an anticipated period of non-driving will be below an anticipated energy consumption by hotel loads during the anticipated period of non-driving.

Abstract
A hybrid electric vehicle control system and process initiates active charging and power rationing control strategies in accordance with determining that a predicted state of charge of an electrical energy storage unit during an anticipated period of non-driving will be below an anticipated energy consumption during the anticipated period of non-driving. The determination is made, and the active charging and rationing are initiated, in advance of the period of non-driving in order to ensure that a state of charge of the electrical energy storage unit is sufficient to supply the anticipated energy consumption during the period of non-driving.
