Title:
CONTROL DEVICE OF HYBRID AUTOMOBILE
Document Type and Number:
Japanese Patent JP3333814
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To achieve a hybrid automobile that can perform retract driving, does not apply load to a capacitor for smoothing of an inverter, and is strong against the control disturbance such as curbstone stranding and slip.
SOLUTION: When the trouble of a main battery 12 is detected, an SMR 24 is turned off for shifting to a retract driving, at the same time transistors Q7-Q12 of an inverter 20 are turned off and the DC output of the inverter 20 is allowed to follow the output fluctuation of a motor 10, thus preventing the output surplus of the inverter 20 leading to the overvoltage charging of smoothing capacitors C1 and C2. Then, even if the output of the motor fluctuates due to, for example, the stranding onto a curbstone, it is possible to follow the fluctuation rapidly.
