摘要： A computer system determines a selected path to be taken by a vehicle. The system monitors alternative paths for the vehicle; based on the monitoring, determines that the vehicle approaches at least two alternative paths having different properties; determines a probability of the vehicle taking each of the at least two alternative paths having different properties; compares the probabilities of the at least two alternative paths to each other; and based on a result of the comparison of the probabilities, selects a selected path amongst the at least two alternative paths.

摘要： A method for thermal conditioning at least one thermal buffer of a thermal system of a vehicle, the thermal system being a rechargeable energy storage system, RESS, and/or an energy transformation system comprising fuel cells, the thermal buffer having an operating window defined by the preferred operating temperature of the thermal buffer. The method includes providing predictive power utilization of the thermal buffer as a function of time, conditioning the thermal buffer in response to the predictive power utilization, such that the thermal buffer is thermally conditioned to be within the operating window of the thermal buffer. The operating window is varying as a function of the predictive power utilization over time.

摘要： A computer-implemented method determines a degradation state of a turbo and/or a humidifier of a fuel cell system for a vehicle. The fuel cell system includes a fuel cell stack, the turbo and the humidifier. The method includes obtaining a fuel cell system efficiency value which corresponds to a measured efficiency decrease of the fuel cell system during use with respect to a first reference efficiency, obtaining a fuel cell stack efficiency value which corresponds to a measured efficiency decrease of the fuel cell stack during use with respect to a second reference efficiency, and determining the degradation state of the turbo and/or the humidifier based on a difference between the fuel cell system efficiency value and the fuel cell stack efficiency value.

摘要： The invention relates to a method for controlling gaseous fuel pressure in an accumulator (12) of a fuel system (10) for a combustion engine (102) of a vehicle (100), wherein the method comprises the steps of: determining a nominal amount of gaseous fuel to be introduced into the accumulator; introducing less gaseous fuel into the accumulator than the determined nominal amount by reducing or closing an inlet valve (24), which inlet valve is adapted to regulate input of gaseous fuel to the accumulator; and while the inlet valve is reduced or closed, performing at least one injection of gaseous fuel coming from the accumulator into at least one combustion chamber (104a-f) of the combustion engine by at least one injector (14a-f) of the fuel system, which at least one injection contributes to combustion in the combustion engine, thereby reducing pressure in the accumulator. The invention also relates to a corresponding fuel system (10).
