[0001] This invention relates to the field of equipment control technology, and in particular to an extreme energy-saving range control method and system for new energy vehicles. Background Technology
[0002] Currently, with the continuous development of new energy vehicles, driving range has become one of the important indicators that users pay attention to;
[0003] However, the existing ECO mode of new energy vehicles mainly achieves energy saving and extends the driving range by adjusting the torque response rate to meet the driver's demand. However, when making energy-saving adjustments, the impact of factors such as the driving environment on energy consumption is not fully considered, which leads to a reduction in the energy-saving range of the vehicle. At the same time, when the battery level on the instrument panel is low, users may move the vehicle to find a charging station without protecting the battery pack from over-discharge, which makes the battery pack prone to over-discharge and greatly reduces the energy-saving range control.

In step 2, the power output and accessory energy consumption of the vehicle are adaptively adjusted based on the real-time battery level of the vehicle during normal driving periods, including:
[0103] The system acquires the ambient temperature during normal driving conditions and prioritizes energy allocation to the vehicle's battery when the ambient temperature is below a preset threshold, and preheats the battery based on the allocation results.
[0104] Based on the preheating results, the vehicle is divided into driving stages. At the same time, the driving segment characteristics of the vehicle are retrieved from the historical database, and the power output of the vehicle in different driving stages is divided into steps based on the driving segment characteristics to obtain a power output parameter reference table.
