The invention relates to the technical field of new energy automobiles, in particular to an energy consumption calculation method and device and an endurance mileage calculation method and device of a parallel hybrid electric vehicle. The energy consumption calculation method comprises the following steps: judging whether an engine is in a direct-drive working condition or a non-direct-drive working condition; if it is judged that the engine is in the direct-drive working condition, the current oil-electricity conversion coefficient and electric quantity energy flow information in the preset operation period are obtained; calculating first unit power consumption in a preset operation period according to the current oil-electricity conversion coefficient and the electric quantity energy flow information; calculating first final power consumption under the direct-drive working condition according to the first unit power consumption; if it is judged that the engine is in the non-direct-drive working condition, electric quantity energy flow information in the preset operation period is obtained, and second unit power consumption in the preset operation period is calculated according to the electric quantity energy flow information; and calculating second final power consumption under the non-direct-drive working condition according to the second unit power consumption. By adopting the method, the accuracy of the energy consumption calculation result of the parallel hybrid electric vehicle can be improved.

    本申请涉及新能源汽车技术领域,尤其是涉及一种并联式混动汽车的能耗计算方法、续航里程计算方法和装置。所述能耗计算方法包括:判断发动机处于直驱工况或非直驱工况;若判断出发动机出于直驱工况,获取预设运行周期内的当前油电转换系数和电量能量流信息;根据当前油电转换系数和电量能量流信息,计算预设运行周期内的第一单位电耗;根据第一单位电耗计算直驱工况下的第一最终电耗;若判断出发动机处于非直驱工况,获取预设运行周期内的电量能量流信息,根据电量能量流信息计算预设运行周期内的第二单位电耗;根据第二单位电耗计算非直驱工况下的第二最终电耗。采用本方法能够提高并联式混合动力汽车的能耗计算结果的精确度。
