Abstract
A method is provided for controlling a hybrid vehicle in an emergency situation. The hybrid vehicle includes an internal combustion engine, a rechargeable electric energy storage system, and an electrical motor drive system. The method includes detecting a failure of a control unit for controlling the electrical motor drive system, disconnecting the rechargeable electric energy storage system from the hybrid vehicle, limiting the maximum speed of the internal combustion engine from a first RPM value to a second RPM value. An apparatus is also provided for controlling a hybrid vehicle in an emergency situation.
