Title:
POWER GENERATION CONTROLLING DEVICE FOR HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP3555396
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce engine noise and vibration arising from charging, while preventing the lack of stored electricity in an electricity storage device when a vehicle is in a state of near halt with its speed dropping to a given value or lower in a power generation controlling device for a hybrid vehicle, which drives a generator with an engine for charging the electricity storage device.
SOLUTION: If it is discriminated that a speed V of a vehicle is equal to a given value α or lower (SA4) and that state of charge SOC is equal to a given capacity β or lower (SA6), target engine speed is reduced by a given value (SA11) so that the current of a motor generator is controlled, in such a way as to generate regenerative braking torque which matches a target engine speed (SA12) to reduce the charging capacity. On the other hand, if the amount of change of the stored electricity capacity ΔSOC becomes negative, the power consumption of an electrical load is lowered (SA and SA4) in such a way that the charging and discharging of an electricity storage device is almost balanced.
