Abstract

The invention provides a power consumption prediction device, a vehicle control device, a vehicle, a power consumption prediction method, and a vehicle control method. The purpose of the invention is to improve the accuracy of predicting the power consumption of an air conditioner. A power consumption prediction device predicts the power consumption consumed by a vehicle equipped with one or more air conditioners operable using battery power and comprises: an occupant number detection unit for detecting the number of occupants in a vehicle; an air conditioner operation number detection unit for detecting the number of operating air conditioners in the vehicle; a cabin temperature detection unit for detecting the temperature in the cabin of the vehicle; an air conditioner setting temperature acquiring unit for acquiring the setting temperatures of the respective air conditioners; and a power consumption prediction unit for, using the number of occupants, the number of operating air conditioners, the cabin temperature, and the air conditioner setting temperatures, predicting the power consumptions of the air conditioners.

Description

technical field [0001] The present invention relates to a technique for predicting power consumption in a vehicle. Background technique [0002] An automobile is equipped with an engine and a battery, and the battery is charged by the power of the engine. Conventionally, there is known a technique for controlling the charging of the battery by suppressing the charging of the battery during normal running to save fuel consumption, and performing this by using regenerative power generation during deceleration running. Charging the battery. [0003] In addition, as a control for saving fuel consumption, there is known an idle stop (also referred to as idle / deceleration) control. Patent Document 1 below discloses an automobile provided with two functions of charging control and idling stop control in response to a demand for fuel economy improvement. [0004] However, in the above-mentioned technology, when the electric power stored in the battery is consumed by the auxiliary...
