Title:
POWER SUPPLY SYSTEM, VEHICLE USING THE SAME, POWER SUPPLY SYSTEM CONTROL METHOD, AND COMPUTER-READABLE RECORDING MEDIUM CONTAINING THE PROGRAM FOR CAUSING COMPUTER TO EXECUTE THE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2008/149826
Kind Code:
A1
Abstract:
A lower limit value setting unit (52) variably sets a lower limit value (Vth) of
a target voltage (Vh*) in a voltage range which is higher than a maximum value in
voltages (Vb1, Vb2) of an accumulation device and is not affected by a dead time
arranged in a converter according to temperatures(Tb1, Tb2) and required powers
(Pb1* Pb2*). A maximum value selection unit (53) sets as the target voltage,
the maximum value among voltages (Vb1, Vb2) of the accumulation device and required
voltages (Vm1*, Vm2*) of a motor generator. A target voltage limit unit (54)
compares the target voltage to the lower limit value (Vth). If the target value
is lower than the lower limit value (Vth), the target voltage control unit (43)
sets the lower limit value (Vth) to be the target voltage (Vh*).
