The invention discloses a vehicle thermal management method and device, a vehicle and a storage medium. The method comprises the following steps: in the driving process of a target vehicle, acquiring battery parameters of the target vehicle, and static road data and dynamic road data of a current driving road section to which the target vehicle belongs; based on the battery parameters, the static road data, the dynamic road data and a pre-constructed linear regression function, determining a predicted battery temperature of the target vehicle in the predicted road section; when it is determined that a preset loss condition is met according to the historical predicted battery temperature and the actual battery temperature of the multiple historical driving road sections, parameter adjustment is conducted on the linear regression function to update the predicted battery temperature; and calling the expected battery temperature, and performing thermal management on the target vehicle based on the predicted battery temperature and the expected battery temperature. The problem that the whole vehicle thermal management efficiency of the battery before charging is low is solved, the thermal management efficiency is improved, and the endurance mileage and safety of the new energy vehicle are improved.

    本发明公开了一种整车热管理方法、装置、车辆和存储介质。其中,方法包括:在目标车辆行驶过程中,获取目标车辆的电池参数,以及目标车辆所属当前行驶路段的静态道路数据以及动态道路数据;基于电池参数、静态道路数据、动态道路数据以及预先构建的线性回归函数,确定目标车辆在预测路段的预测电池温度;在根据多个历史行驶路段的历史预测电池温度和实际电池温度,确定满足预设损失条件时,对线性回归函数进行参数调整,以更新预测电池温度;调取期望电池温度,基于预测电池温度和期望电池温度,对目标车辆进行热管理。解决了针对充电前的电池进行整车热管理效率较低的问题,提高了热管理效率,提高新能源汽车的续航里程以及安全性。
