The invention belongs to the technical field of new energy vehicles, and provides a fuel cell vehicle thermal management system and method and a fuel cell vehicle. According to the fixed road spectrum vehicle running process control method, the following working condition of a vehicle is predicted through the running time and the fixed road spectrum of vehicle running; different vehicle management strategies are operated according to different prediction results; the working condition of the fuel cell can be changed in advance during switching of different operation strategies, so that the working condition changing time of the fuel cell is prolonged, the impact on the fuel cell is reduced, and the service life of the fuel cell is prolonged; the strict requirements of transient working condition changes of the fuel cell on the thermal management system are effectively reduced, and stable work, energy conservation and emission reduction of the thermal management system are achieved.
本发明属于新能源汽车技术领域,提供了一种燃料电池汽车热管理系统、方法及燃料电池汽车,本发明提供的固定路谱车辆运行过程控制方法,通过行驶时间与车辆行驶的固定路谱预测车辆接下来的工况,根据不同的预测结果运行不同的车辆管理策略;在不同的运行策略切换中可以提前使燃料电池进行工况的改变,延长燃料电池工况改变的时间,降低对燃料电池的冲击,从而延长燃料从电池寿命;有效的降低了燃料电池瞬态工况变化对热管理系统的严苛要求,实现热管理系统的稳定工作与节能减排。
