REGENERATION CONTROL UNIT

摘要

PROBLEM TO BE SOLVED: To provide a regeneration control unit capable of ensuring appropriate power consumption and improving driving feel.SOLUTION: In a regeneration control unit 10 for a hybrid electric vehicle, a first motor 1 that drives a vehicle 20 and generates regenerative power and a second motor 2 that is driven by an engine 3 to generate power and functions as a driving motor for the engine 3 are provided. A condition determination unit 11 that determines whether or not a state is a state where charging of a battery 5 is restricted is provided. A target-power-consumption calculation unit 12 that calculates target power consumption which is a target value of electric power consumed when the second motor 2 drives the engine 3 to rotate using the regenerative power generated by the first motor 1 at a time of the regenerative power generation by the first motor 1 is provided. An actual-power-consumption calculation unit 13 that calculates actual power consumption of the second motor 2 required to maintain rotating speeds of the engine 3 and the second motor 2 is provided. An acceleration control section 14 that increases or decreases rotation accelerations of the engine 3 and the second motor 2 on the basis of the difference between the target power consumption and the actual power consumption.SELECTED DRAWING: Figure 1
