The invention discloses a hydrogen fuel cell vehicle cruising ability test system, which comprises a combination instrument system, a vehicle control unit, a fuel cell control system, a new energy battery management system and a vehicle body electronic stabilization system, and is characterized in that the combination instrument system comprises a total cruising mileage display module and a total cruising mileage calculation module; the total endurance mileage calculation module is connected with a hydrogen endurance mileage calculation module and a power endurance mileage calculation module through a can bus, and a testing method for the endurance ability of the hydrogen fuel cell vehicle comprises the steps of pure hydrogen endurance mileage calculation, pure power endurance mileage calculation, total endurance mileage calculation and the like. The hydrogen endurance mileage is calculated according to the real-time residual hydrogen amount and nearly 100km driving hydrogen consumption, the driving working condition is comprehensively considered, and the problem of hydrogen-electricity conversion efficiency is avoided; and a dynamic correction coefficient is added in the power endurance mileage calculation process, influence factors such as working conditions and temperature are comprehensively considered, the total endurance mileage is summed by hydrogen endurance and power endurance and complements with a combination instrument system, and the calculation result is relatively accurate.

    本发明公开了一种氢燃料电池车续航能力的测试系统,包括组合仪表系统、整车控制器、燃料电池控制系统、新能源电池管理系统和车身电子稳定系统,组合仪表系统包括总续航里程显示模块和总续航里程计算模块,总续航里程计算模块通过can总线连接有氢续航里程计算模块和电续航里程计算模块,一种氢燃料电池车续航能力的测试方法,包括计算纯氢续航里程、计算纯电续航里程、计算总续航里程等步骤,氢续航里程根据实时剩余氢量、近100km的行驶氢耗计算所得,综合考虑了行驶工况,避开氢电转化效率问题;电续航里程计算过程中加入动态修正系数,综合考虑工况、温度等影响因素,总续航里程由氢、电续航求和,与组合仪表系统相互补充,计算结果相对准确。
