Abstract
Disclosed is a system and method for determining when an engine of a hybrid electric vehicle has abnormally stalled. In particular, a control unit is configured to determine whether an entry condition has been satisfied before determining whether the engine stalled. Then once it is determined that the engine has stalled, the control unit increase a stall count and monitors whether the engine enters a normal operation state. If the engine enters a normal state, the control unit decreases the stall count. However, when the stall count is greater than or equal to a predetermined threshold value it is determined that the engine is out of order. Thus, it can be clearly identified when an engine has stalled abnormally and over-discharging of the battery may be avoided.
