A method for determining and optionally additionally implementing an optimal route for a vehicle that has an electrical drive system having an energy storage device, and a converter to charge the energy storage device.

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.

A vehicle has an engine, a fuel tank, and a controller configured to selectively operate the engine, during one or more drive cycles, until a specified fraction of fuel from the tank has been consumed in response to expiration of a predefined time period to limit fuel degradation. A powertrain system has a traction battery, an engine, a fuel tank, and a controller configured to selectively operate the engine in response to a quality of fuel in the tank being below a threshold until a specified fraction of fuel has been consumed, thereby limiting fuel degradation. A method of controlling a vehicle includes, in response to expiration of a predefined time period, selectively operating an engine, during one or more vehicle drive cycles, such that state of charge of a traction battery is generally maintained until a specified fraction of fuel in a fuel tank has been consumed to limit degradation of the fuel.

The present invention provides a hybrid vehicle, including a power battery, a fuel storage tank, an electrical power generation unit, a pressure detection unit and a work mode controller, and adopts a pressure protection mode under the work mode controller, wherein the work mode controller is configured to control the vehicle to enter the pressure protection mode when the electrical power generation unit is in a stop state and when the gas pressure detected by the pressure detection unit is higher than a pressure threshold; and in the pressure protection mode, the electrical power generation unit is started from the stop state to enter the working state to consume the fuel in the fuel storage tank, and the gas pressure in the fuel storage tank is accordingly reduced. As the pressure protection mode is adopted in the present invention, the electrical power generation unit can be automatically started according to the gas pressure of the fuel in the fuel storage tank to charge the power battery using the expanded redundant fuel. The safety problem and the waste resulting from the fact that the expanded fuel exceeding the threshold in the fuel storage tank is discharged into the atmosphere in the prior art are avoided.
