Abstract: 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 β. 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.

As a result, the torque based on the maximum slip speed Vsmax without vibration is output from the motor as compared to a case where the torque based on the slip speed Vs with vibration is output from the motor.

Abstract: PROBLEM TO BE SOLVED: To stop an internal combustion engine within a target stop range with higher accuracy.SOLUTION: When an engine operation is to be stopped during deceleration travel as a brake pedal is depressed, correction torque Tadj is set so that torque for reducing engine rotation speed is smaller as a brake pedal position BP (brake pedal force) from a brake pedal position sensor is larger (S130), and base torque Tbase is corrected with the correction torque Tadj to set a torque command Tm1*, thus drive-controlling a motor MG1 (S140, S150). Thereby, the engine can be stopped with stable brake torque regardless of a depressing state of the brake pedal, so that the engine can be accurately stopped at a crank angle within a target stop range suitable for next start-up.
