The invention belongs to the technical field of new energy vehicles, and particularly relates to a fuel cell whole vehicle thermal management system control method and a vehicle. The control method comprises the steps that when heating is needed in a compartment, if a fuel cell is in a working state, fuel cell waste heat utilization and a vehicle-mounted air conditioner are started, and when the temperature of the compartment reaches a set target temperature, the vehicle-mounted air conditioner is started; only the vehicle-mounted air conditioner is turned off, and the fuel cell waste heat is kept in a working state. When a fuel cell is in a working state, a vehicle-mounted air conditioner is started, waste heat utilization of the fuel cell is achieved, the temperature of a compartment is rapidly increased, when the temperature of the compartment is increased to a set target temperature, the vehicle-mounted air conditioner is closed, and at the moment, waste heat utilization of the fuel cell is still kept in the working state; due to the fact that the waste heat utilization of the fuel cell can maintain the temperature in the vehicle within a certain time, the temperature in the vehicle is not reduced, more heat is transferred into the vehicle by keeping the starting state of the waste heat utilization of the fuel cell, and the temperature reduction in the compartment can be slowed down.
本发明属于新能源汽车技术领域,具体涉及一种燃料电池整车热管理系统控制方法及车辆,控制方法包括:当车厢内部有加热需求时,若燃料电池处于工作状态,则开启燃料电池余热利用和车载空调,当车厢温度达到设定目标温度时,仅关闭车载空调,燃料电池余热利用保持工作状态。通过燃料电池处于工作状态时,开启车载空调以及燃料电池余热利用,快速提升车厢温度,并且当车厢温度升高至设定目标温度时,关闭车载空调,此时燃料电池余热利用依旧保持工作状态,因燃料电池余热利用能够在一定时间内维持车内的温度,使车内温度不降低,所以通过保持燃料电池余热利用的开启状态,为车内传递更多热量,能够减缓车厢内温度下降。
