Abstract

The invention discloses a power-saving mode control method and system and an electric vehicle, and the method comprises the steps: responding to a received power-saving mode opening instruction, entering a power-saving mode, obtaining the current state of charge (SOC) of a storage battery, judging the electric quantity section of the SOC, and starting the power-saving mode; the corresponding vehicle speed limit, the energy recovery intensity and the forbidden system range are matched according to the electric quantity section where the current state of charge (SOC) of the storage battery is located, and the vehicle is correspondingly controlled; wherein different maximum vehicle speed limits, different energy recovery intensities and different system forbidding ranges are preset in different electric quantity sections. By means of the power-saving mode control method, basic driving requirements can be met, the endurance mileage is increased, and mileage anxiety is relieved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a power-saving mode control method and system thereof, and an electric vehicle. Background technique [0002] Affected by energy crisis, environmental pollution and greenhouse effect, new energy vehicles, especially pure electric vehicles, will become an inevitable trend. Pure electric vehicles have the advantages of energy saving, environmental protection, strong power, and simple structure, and have attracted extensive attention from scientific research institutions and enterprises. Today, with the increasingly rich functions of automobiles, electrified smart cars provide drivers with a variety of driving experiences, and the demand for battery power is increasing. However, due to the inherent properties of batteries, the charging time is longer and the coverage of charging piles is low. And other problems, often cause mileage anxiety.
