PROBLEM TO BE SOLVED: To provide a power consumption rate calculating device for a vehicle that can learn power consumption so that it would not cause a driver to have a sense of discomfort when a driving range is calculated based on an amount of electricity stored in a battery for traveling.SOLUTION: When calculating a driving range by calculating a this-time learned power consumption ECby reflecting a zone power consumption for this time EC' on a previous-time learned power consumption EC, if the zone power consumption for this time EC' worsens relative to the previous-time learned power consumption EC, a deviation toward the side the this-time learned power consumption ECworsens is regulated by a power consumption learning rate α, and if the zone power consumption for this time EC' is better than the previous-time learned power consumption EC, a deviation toward the side the this-time learned power consumption ECis better is regulated by a power consumption learning rate &bgr;. By this method, a driver's sense of discomfort due to a large change in the driving range that is caused by a large change in this-time learned power consumption ECcan be prevented. |
