Abstract
A hydrogen discharge control system controls a hydrogen discharge flow rate in a hydrogen engine vehicle that discharges hydrogen from a hydrogen tank in which a resin liner is laminated on an inner wall, to a hydrogen engine, in accordance with an accelerator operation amount. The hydrogen discharge control system comprises a control device. The control device estimates a temperature attained in the hydrogen tank after a predetermined time elapses with the accelerator operation amount at a maximum during an on operation of an accelerator, based on a temporal temperature gradient in the hydrogen tank and a temperature in the hydrogen tank, and when the temperature attained is no higher than a first predetermined temperature, performs discharge limit control for limiting a maximum value of the hydrogen discharge flow rate from the hydrogen tank to a predetermined flow rate.
