To more stabilize braking force even when a scavenging process is performed during the use of a regeneration-friction cooperative brake in a fuel cell vehicle.SOLUTION: A fuel cell vehicle includes a fuel cell, a gas supply unit, a friction brake system, a drive motor, a power storage device, and a control unit which executes control for using friction braking force and regenerative braking force to obtain requested braking force and control for performing a scavenging process. While the fuel cell vehicle is braked by the friction braking force and the regenerative braking force, the control unit uses the amount of stagnant water stagnating inside the fuel cell to determine whether a scavenging preparation condition is satisfied. The control unit executes a responsiveness enhancement process when the scavenging preparation condition is satisfied, and executes the scavenging process when the responsiveness enhancement process is completed, and the amount of the stagnant water reaches a reference value.SELECTED DRAWING: Figure 6
【課題】燃料電池車両において、回生摩擦協調ブレーキの使用時に掃気処理する際にも制動力をより安定させる。【解決手段】燃料電池車両は、燃料電池と、ガス供給部と、摩擦ブレーキシステムと、駆動モータと、蓄電装置と、摩擦制動力と回生制動力とを用いて要求された制動力を得る制御と掃気処理を行なうための制御とを実行する制御部と、を備える。制御部は、摩擦制動力と回生制動力とによって燃料電池車両が制動中であるときに、燃料電池の内部に滞留する滞留水の量を用いて掃気準備条件を満たすか否かを判断し、掃気準備条件を満たすときに応答性向上処理を実行し、応答性向上処理が完了し、且つ、滞留水の量が基準値に達したときに掃気処理を実行する。【選択図】図6
