The invention provides a control method and system of a vehicle water pump and a vehicle. The method comprises the following steps that a cooling requirement of the vehicle and the current gear of thevehicle are obtained; whether the cooling requirement is smaller than a first preset threshold value or not is judged; and if the cooling requirement is smaller than the first preset threshold valueand the current gear of the vehicle is the first preset gear, the water pump is controlled to operate at the first preset duty ratio. Therefore, the operation duty ratio of the water pump is reasonably controlled through combination of the cooling requirement and the current gear, the performance of the water pump is optimized, certain extreme working conditions can be covered, the safety of the whole vehicle can be improved, meanwhile, energy is saved, and the vehicle driving range is increased.
本发明提供了一种车辆水泵的控制方法、系统及车辆,该方法包括以下步骤:获取车辆的冷却需求及车辆当前的挡位;判断冷却需求是否小于第一预设阈值;如果冷却需求小于第一预设阈值,且车辆当前的挡位为第一预设挡位,则控制水泵以第一预设占空比运行,从而结合冷却需求和当前挡位来合理控制水泵的运行占空比,优化水泵的性能,能够涵盖某些极端工况,能够提高整车安全性,同时节约能源,提高车辆续驶里程。
