Title:
MOTOR-DRIVEN CONTROL SYSTEM AND ITS CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2007/111286
Kind Code:
A1
Abstract:
In a motor-driven control system configured with a converter which can be boosted, while no lock state of MG (2) operating as a motor is generated (NO in S130), a voltage instruction value VHref of a converter output voltage is set in accordance with a required voltage of MG (1) and MG (2) operating as motors (S140). On the other hand, when a lock state of the MG (2) is generated (YES in S130), the voltage instruction value VHref is set to a limit voltage V1 mt or below so as to limit boosting in the converter (S150, S160). When the lock state is generated, the converter output voltage is lowered so as to lower the DC voltage switched by the inverter, which in turn reduces the switching loss in the switching element constituting the inverter and suppresses the temperature increase by the heating.
