The invention discloses a low-temperature integrated thermal management control method for a pure electric vehicle. The method comprises the steps that S1, current state information of the vehicle is collected; s2, predicting the expected acceleration of the vehicle at the next moment according to the vehicle speed of the vehicle in the current state; s3, the vehicle driving power is calculated according to the expected acceleration; s4, the optimal battery heating power and the optimal passenger compartment heating power are solved; and S5, respectively heating the battery and the passenger compartment through the optimal battery heating power and the optimal passenger compartment heating power. The heating power of the battery and the heating power of the passenger compartment can be reasonably distributed, the dynamic property of the whole vehicle is improved, and the comfort of the passenger compartment is improved.
本发明公开了一种纯电动汽车低温集成热管理控制方法,包括:S1.采集车辆当前状态信息;S2.根据车辆当前状态下的车速,预测车辆在下一时刻的期望加速度;S3.根据期望加速度计算得到车辆驱动功率;S4.求解最优的电池加热功率和最优的乘员舱加热功率;S5.通过最优的电池加热功率和最优的乘员舱加热功率分别对电池以及乘员舱进行加热。本发明能够对电池加热功率和乘员舱加热功率进行合理分配,提升了整车动力性以及提高了乘员舱舒适性。
