Abstract

A system and method for controlling transition of a fuel cell vehicle from a normal operating mode to a hot operating mode comprising a fuel saving operating mode. The method comprises determining a required value of a traction power from the fuel cell system for the fuel cell vehicle; determining a net electric power output value of the fuel cell system based on a fuel cell system power output and a cooling electrical power value; and controlling the fuel cell vehicle to transition from the normal operating mode to the hot operating mode via a first transition mode or via a second transition mode so that the net electric power output value is equal to the required value of the traction power and a coolant inlet temperature at a coolant inlet of a fuel cell stack of a fuel cell system of the fuel cell vehicle is equal to a hot coolant temperature.
