摘要： A fail-safe method and apparatus for high voltage parts in a hybrid vehicle is provided. In the fail-safe method, it is determined whether or not a high voltage main relay is turned off. Here, when the high voltage main relay is turned off, a voltage is charged into a direct current (DC) link using a counter electromotive force generated in a motor generator linked with a revolution of an engine. Voltage control is performed such that the voltage of the DC link is uniformly maintained using an inverter for the motor generator.

摘要： Disclosed is a method for controlling a permanent magnet synchronous motor to maximize use of voltages of a battery by voltage phase control within weak magnetic flux area and to achieve compensation for a torque error through a torque compensator when driving the permanent magnet synchronous motor for hybrid vehicles. In particular, the method controls a permanent magnet synchronous motor so that voltage use can be maximized in a weak magnetic flux area by using voltage near maximum voltage through voltage phase control utilizing magnetic flux-based map data receiving a torque command and motor speed/batter output voltage as inputs and torque error can be compensated using a torque compensation filter when a motor constant is changed in the weak magnetic flux by a circumstance parameter, when the permanent magnet synchronous motor mounted in a hybrid vehicle and an electric vehicle is driven.
