Abstract
The present disclosure provides a multi-stage method to extend the range of a vehicle. The method includes taking progressive actions on a vehicle as the state of charge (SOC) drops below defined levels. The method may include monitoring the SOC of the vehicle in relation to a SOC threshold or monitoring the SOC of the vehicle in relation to the distance remaining to a predetermined destination.
Claims20
A method for extending a range of a vehicle, comprising:
- acquiring vehicle information relative to a multistage conservation step criteria, wherein the multistage conservation step criteria includes at least one of a current state of charge (SOC) of an energy storage device and current operating conditions of the vehicle;
- determining whether the vehicle satisfies the multistage conservation step criteria based on an ability of the vehicle to complete a mission;
- and executing a sequence of conservation steps in stages, wherein each stage progressively restricts vehicle performance in response to the determination.
A method for controlling energy usage in a vehicle, comprising:
- acquiring SOC data and operating condition data of the vehicle;
- evaluating the SOC data and operating condition data against a multistage conservation step criteria, the conservation step criteria comprising a determination of whether the vehicle can complete a mission prior to reaching a destination or depleting the SOC below a minimum reserve;
- and initiating a multistage sequence of performance-limiting actions, each stage corresponding to a worsening state of the vehicle's ability to complete the mission.
A method for mission-based vehicle range extension, comprising:
- determining a destination and a remaining distance to the destination;
- acquiring a state of charge (SOC) of a vehicle energy storage device and determining a projected SOC at the destination;
- evaluating whether a mission criterion is satisfied, the mission criterion comprising whether the projected SOC is sufficient to complete the mission to the destination;
- and initiating a plurality of energy conservation stages, each stage imposing a progressively greater restriction on vehicle performance as the projected SOC decreases or fails to meet the mission criterion.
