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.
Claims17
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, GPS information, energy storage system (ESS) information, accessory information, and system default parameters;
- calculating a charging strategy based upon the energy forecast and the plurality of strategy variables;
- determining a control strategy for energy allocation based upon the strategy variables, energy forecast, and charging strategy;
- allocating energy to vehicle systems based upon the control strategy including limiting at least one of a plurality of vehicle functions when the energy forecast predicts that the vehicle has insufficient power;
- and
- monitoring the vehicle route and recalculating the energy forecast, the charging strategy and the control strategy of the vehicle when the vehicle deviates from one of a predetermined route and the calculated energy forecast.
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, GPS information, energy storage system (ESS) information, accessory information, and system default parameters;
- calculating a charging strategy based upon the energy forecast and the plurality of strategy variables;
- determining a control strategy for energy allocation based upon the strategy variables, energy forecast, and charging strategy;
- allocating energy to the vehicle systems based upon the control strategy including limiting at least one vehicle function when the energy forecast predicts that the vehicle has insufficient power for the route and charging strategy calculated;
- and
- wherein limiting the at least one vehicle function continues until one of the vehicle reaches the destination and the vehicle forecast indicates the vehicle has sufficient energy based upon the predicted energy forecast.
