Abstract
A method of controlling a battery electric vehicle includes displaying an energy consumption parameter to a vehicle operator. The energy consumption parameter is based on a filtered energy usage rate. The filtered energy usage rate is defined by a weighted incremental energy consumption rate measured over a first distance and an average energy consumption rate learned over a second distance. The second distance exceeds the first distance.
Claims14
A method of controlling a battery electric vehicle comprising:
- supplying power from a vehicle battery;
- and
- displaying, to a vehicle operator, an energy consumption parameter that is based on a filtered energy usage rate in which an incremental energy consumption rate measured over a first distance is input to a distance-domain filter and weighted with a factor based on the first distance and a reference distance that is greater than the first distance.
A vehicle comprising:
- a battery;
- a display configured to signal information to a vehicle operator;
- and
- a controller configured to signal a vehicle energy consumption rate via the display, and programmed to output the vehicle energy consumption rate based on distance-domain filtering an incremental energy consumption rate measured over a first distance with a weighting factor based on the first distance and a reference distance that is greater than the first distance.
A method of controlling a vehicle comprising:
- transferring power between a traction battery and a traction motor;
- and
- displaying, to a vehicle operator, a vehicle energy consumption parameter that is based on a weighted function of a first energy consumption value and a second energy consumption value, the first energy consumption value corresponding to an incremental energy consumption rate over a first distance and the second energy consumption value corresponding to a stored energy consumption rate over an accumulated distance, and the filter having weighting factors based on the first distance and a reference distance, wherein the weighted function is a first-order distance-domain filter.
