CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2019131065
Kind Code:
A
Abstract:
To prevent insufficiency of power required to prepare start of an internal combustion engine.SOLUTION: A control device 200 for a vehicle 100 comprises: a power supply control unit that controls power supply to a rotary electric machine 40 such that when a vehicle travels with use of only power of the rotary electric machine 40, power output from a second battery 60 compensates for insufficient power output from a first battery 50; and a start preparation initializing unit that initializes a start preparation for an internal combustion engine 10 by initializing power supply to a catalyst device 15 when an amount of charge of the second battery 60 decreases lower than an amount of charge for start preparation during travel with use of only power of the rotary electric machine 40. The start preparation initializing unit is configured to increase an amount of charge for start preparation when it is small compared to the case where the maximum output power of the first battery 50 calculated based on a state of the first battery 50 is large.SELECTED DRAWING: Figure 1
