Embodiment Construction

[0040] The equivalent fuel consumption factor calibration system and method proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. However, the present invention can be implemented in different forms and should not be limited to the described embodiments. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0041] Due to the existing equivalent fuel consumption factor calibration method, in order to find the optimal calibration parameters, it is necessary to arrange a lot of drum tests, and each drum test takes about 15 minutes, plus the preparation time before the test, it takes about 15 minutes for each drum test. T...

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a system and method for calibrating equivalent fuel consumption factors. Background technique [0002] Control strategy is one of the core technologies of hybrid electric vehicles, which directly affects the economy and power of hybrid electric vehicles, such as torque distribution strategy. The minimum equivalent fuel consumption algorithm ECMS is an algorithm based on an optimized energy management control strategy. Based on the torque distribution strategy of the minimum equivalent fuel consumption algorithm ECMS, the engine output power and electric energy can be achieved at any time under the premise of meeting the driver's demand torque. The sum of equivalent power consumption is the smallest. The function here defines the equivalent fuel consumption factor (S-factor), which equates electric energy consumption to fuel consumption. [0003] The calibration...
