  • Patent number: 11024861
    Abstract: A fuel cell vehicle performs a control for increasing a flow rate of a cathode gas discharged to a discharge pipe when parameters including power consumption of a driving motor, a speed, and an acceleration has satisfied a flooding condition which is assumed to be satisfied in a state where a water surface reaches a discharge port in comparison with a case where the flooding condition is not satisfied. It is determined that the predetermined flooding condition has been satisfied when a state where at least three conditions, (i) the power consumption of the driving motor is equal to or greater than a predetermined first threshold value, (ii) the speed is equal to or less than a predetermined second threshold value, and (iii) the acceleration is equal to or less than a predetermined third threshold value, are satisfied is continuously maintained for a predetermined fourth threshold value or more.

  • Patent number: 8731757
    Abstract: The present invention provides a control apparatus which includes a load predicting part configured to predict, based on current load information of an engine rpm controlling part, a load of the engine rpm controlling part at a time point which is a predetermined time ahead of the present time point, the engine rpm controlling part being configured to control an engine rpm; and an engine rpm reducing part configured to reduce the engine rpm if the load predicted by the load predicting part is greater than or equal to a first threshold.
