Title:
VEHICLE POWER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/007626
Kind Code:
A1
Abstract:
An ECU executes a program including: a step (S100) for calculating a regenerative
power value P according to a braking pressure; a step (S102) for calculating a
battery charge power limit value WIN (B); a step (S104) for calculating a capacitor
charge power control limit WIN (C); a step (S108) which estimates that a large
regenerative energy is generated so as to fully charge the capacitor even if the
battery is charged with a higher priority when the regenerative power value P
is judged to be greater than the sum of WIN(B) and WIN(C) (Yes in S106); and a step
(S110) which transmits a control signal to reduce the output voltage of a boosting
converter to a value lower than the capacitor voltage so as to charge the battery
with a higher priority.
