摘要:
A fuel cell system where, when a vehicle mounted with the fuel cell system travels using electric power supplied from the system, predetermined portions of a fuel cell etc. forming the system are prevented from being frozen by the relative wind. The fuel cell system is mounted on a vehicle and has the fuel cell for generating electric power by using fuel gas and oxidized gas as the fuel and also has a control section for controlling the system. When the speed of the vehicle is higher than or equal to a predetermined threshold and predetermined conditions determined by physical quantities relating to power generation conditions of the fuel cell are satisfied, the control section determines that freeze prevention processing is necessary even if the fuel cell is generating electric power and performs the processing.

The invention relates to a motor vehicle with a hybrid drive system (6, 8, 10) and a fuel cell system (14). The fuel cell system (14) is continuously operated within a given operating range or an operating point of high efficiency when in the operating state, whereby a possible energy excess may be supplied to an energy acceptor (8, 10, 12, 22, 24) in order to maintain the energy demand on the fuel cell system necessary for the high efficiency.

A method and system for adaptively controlling a hybrid vehicle comprises a recorder (20) for recording a historical load or duty cycle of vehicle during or after operation of the vehicle. A classifier (24) classifies the historical load in accordance with a load category. A controller (22) assigns at least one of a current control curve and a slew rate control curve associated with the load category for a defined time period after the recording of the historical load or if the vehicle is presently operating generally consistent with the load category. At least one of the current control curve and the slew rate control curve, or data representative thereof, are used to control an operation of an electric drive motor (14) of the vehicle for the defined time period.
