Abstract
The present disclosure is to provide a method of controlling limp home driving of a hybrid vehicle. When the hybrid vehicle enters into a limp home driving mode with a starter generator malfunctioning, a motor control unit performs constant voltage control on counter electromotive force of a motor, so that a constant voltage is supplied to high-voltage components as an input voltage, thereby ensuring that high-voltage components are protected and operable.
