The invention provides a whole vehicle energy consumption optimization method. Each starting time period of each cooling component is related to the information representing the temperature of each cooled component at each moment and the starting temperature limit value and the closing temperature limit value of each cooling component; the information representing the temperature of each cooled part at each moment and the starting temperature limit value and the closing temperature limit value of each cooling part are both related to the control strategy, so that in the whole vehicle energy consumption optimization method, the opening and closing of each cooling part are influenced by the control strategy; besides, the energy consumption of the whole vehicle is obtained through simulation according to the state parameters of the cooled parts at the moments, the accessory power of the cooling parts at the moments and the starting time periods of the cooling parts, so that the energy consumption of the whole vehicle can be optimized in the mode that opening and closing of the cooling parts are affected by control strategies. And the influence of each cooling component on the energy consumption of the whole vehicle is considered, so that the energy consumption optimization of the whole vehicle is more accurate, and the economic performance of the vehicle can be further improved.
本申请提供了一种整车能耗优化方法。由于各冷却部件的各开启时段与表征各被冷却部件在各个时刻的温度的信息以及各冷却部件的开启温度限值和关闭温度限值相关,而表征各被冷却部件在各个时刻的温度的信息以及各冷却部件的开启温度限值和关闭温度限值均与控制策略相关,所以该整车能耗优化方法中,各冷却部件的开闭受到控制策略影响;另外,由于根据各被冷却部件在各个时刻的状态参数、各冷却部件在各个时刻的附件功率和各冷却部件的各开启时段,仿真获得整车能耗,所以该整车能耗优化方法可以以各冷却部件的开闭受到控制策略影响的形式,考虑各冷却部件对整车能耗造成的影响,进而使得对整车能耗优化更加精确,即可以进一步提升车辆的经济性能。
