The invention relates to the technical field of heat control of vehicles, in particular to a control method of a vehicle water circulation system and the vehicle water circulation system. The vehicle water circulation system comprises a supply loop and water use loops, the water use loops are connected to the supply loop in parallel, and each water use loop is provided with a stop valve used for controlling on-off. The control method comprises the steps that when the water using loop is communicated with the supply loop, the fluctuation amplitude of water pressure in the supply loop is obtained, whether the fluctuation amplitude is larger than a preset value or not is judged, and if yes, the interval duration of opening and closing actions of the stop valve is controlled to be increased. According to the vehicle water circulation system, the pipelines of the vehicle water circulation system are arranged in the mode that the water use loops and the supply loops are connected in parallel, the pipelines arranged on the chassis can be greatly simplified, the space of the chassis is saved, the installation and maintenance difficulty of the pipelines is lowered, and the action interval duration of the stop valve is controlled through the fluctuation amplitude; and mutual interference of a plurality of water use loops in the water use process can be avoided.
本发明涉及车辆的热量控制技术领域,特别是涉及一种车辆水循环系统的控制方法及车辆水循环系统。车辆水循环系统包括:供给回路和用水回路,若干个所述用水回路并联在所述供给回路上,所述用水回路设有用于控制通断的截止阀;控制方法为:当所述用水回路与所述供给回路连通时,获取所述供给回路中水压的波动幅度,判断所述波动幅度是否大于预设值,若是,则控制增大截止阀开关动作的间隔时长。本发明中,车辆水循环系统的管路设置为多个用水回路与供给回路并联的形式,能够大大简化布置在底盘的管路,既节省了底盘的空间又降低了管路的安装和维护难度,通过波动幅度控制截止阀的动作间隔时长,能够避免多个用水回路在用水过程中相互干扰。
