A hybrid vehicle having an electric drive with a power accumulator, a fuel cell, and a control unit configured to control the operation of the fuel cell. The control unit has logic, at least partially including hardware configured to activate and deactivate the fuel cell as a function of a first characteristic map having a first input variable representing a present power demand of the hybrid vehicle which exists over a first defined observation time range.

Disclosed in the present invention is a dual-structured power output apparatus of an electric drive and power system that provides a means for outputting both mechanical power and electrical power. It comprises dual motor/generators having two stator assemblies, two rotor assemblies and a power transmission unit all integrated into a single housing for easy mounting. The power transmission unit is disposed adjacent to the two motor/generators and coupled on both ends to rotating shafts mechanically linked to the rotor assemblies such that they are rotatable relative to each other. It function is to change the rotational speed and torque of at least one of the rotors in order to reduce weight and physical size of the apparatus, and thus significantly improving the power density and capability. The structure of the apparatus is well-suited to improve the performance and fuel efficiency of the prior art hybrid powertrain.

A method and system for controlling a fuel cell vehicle are provided. The method includes determining, by a controller, a driving pattern of a driver based on driving information including acceleration and deceleration information. A condition for activation of an idling-stop of a fuel cell is then set based on the determined driving pattern and the fuel cell is stopped from generating electric energy when the condition for activation of the idling-stop is satisfied.

An automotive vehicle drive unit, comprising a fuel cell whose control input is a setpoint of the electrical power to be delivered by the fuel cell. There is a reversible electrical energy storage system and an electric motor to propel the wheels of a vehicle. An electrical connection element selectively connects the fuel cell and/or the energy storage system to the electric motor. A control circuit stores a model of the consumption of dihydrogen as a function of the power delivered by this fuel cell, in the form of a second-degree polynomial and is configured to compute a coefficient of power distribution 1 between the fuel cell and the electrical energy storage system pursuant to a defined equation. The control circuit controls the electrical connection element to recharge the energy storage system when the value of the power setpoint Pfc* is greater than the power demanded by the electric motor.
