Integrated hybrid vehicle control strategy
First Claim
1. A method for allocating energy within a vehicle, comprising:
- calculating an energy forecast for the vehicle based upon a plurality of strategy variables in a vehicle controller, wherein the plurality of strategy variables include;
driver profile information, global positioning system (GPS) information, energy storage system (ESS) information, accessory information, and system default parameters;
calculating a charging strategy based upon;
the calculated energy forecast, and the plurality of strategy variables;
determining a control strategy for energy allocation based upon;
the plurality of strategy variables, the calculated energy forecast, and the calculated charging strategy;
allocating energy to vehicle systems based upon;
the determined control strategy including;
limiting at least one of a plurality of vehicle functions when the calculated energy forecast predicts that the vehicle has insufficient power; and
monitoring a vehicle route forrecalculating;
the energy forecast and the charging strategy for determining a new control strategy of the vehicle when the vehicle deviates from one of a predetermined route and the calculated energy forecast.

Abstract
A method for allocating energy within a vehicle comprises calculating an energy forecast for the vehicle based upon a plurality of strategy variables in a vehicle controller. The plurality of strategy variables includes driver profile information, GPS information, ESS information, environment information, accessory information, and system default parameters. The controller calculates a charging strategy based upon the energy forecast and the plurality of strategy variables and determines a control strategy for energy allocation based upon the strategy variables, energy forecast, and charging strategy. The energy is allocated to the vehicle systems based upon the control strategy.
