Method And Device For Controlling Fuel Cell Power Generation During Regenerative Braking Using Forward Driving Information Of A Fuel Cell Vehicle

An apparatus for controlling fuel cell power generation of a vehicle, the apparatus comprising:

• a peripheral device configured to obtain driving information about at least two upcoming segments of a road, wherein the at least two upcoming segments of the road are segments of the road to be driven by the vehicle driving on a current segment of the road, and wherein the driving information comprises at least one of:
• a speed limit of a moving object on the road or a presence of a gradient and gradient-related data;
• a processor;
• and
• a memory storing at least one instruction that, when executed by the processor, is configured to cause the apparatus to:
• estimate, based on the obtained driving information, a required fuel cell output value of the current segment,
• determine, based on the current segment being a segment for regenerative braking and based on the required fuel cell output value, whether to perform fuel cell power generation control of the vehicle, and
• control, based on the determination, power generation of a fuel cell of the vehicle.

A vehicle comprising:

• one or more sensors configured to obtain gradient information about at least two upcoming segments of a road comprising a current segment on which the vehicle is driving;
• a battery;
• and
• a processor;
• and
• memory storing instructions that, when executed by the processor, configure the vehicle to:
• determine a regenerative charging amount of the battery by performing a regenerative braking operation during driving of the vehicle on the current segment of the road;
• determine, based the gradient information and based on the regenerative charging amount, whether to charge the battery by additional power generated by a fuel cell of the vehicle or to discharge the battery;
• and
• control an operation of the vehicle by:
• controlling, based on a determination to charge the battery by the additional power generated by the fuel cell, an amount of power generated by the fuel cell of the vehicle;
• or
• controlling, based on a determination to discharge the battery, an amount of charge to be discharged from the battery.
