Abstract

The invention discloses an energy consumption mode selection method of a hybrid electric vehicle (HEV). The method comprises the steps of obtaining the current position of the HEV; obtaining the current real-time working condition of the HEV according to the current position of the HEV; obtaining destination information input by a user; obtaining the stroke distance of the HEV according to the current position of the HEV and the destination information; and selecting an energy consumption control mode according to the current real-time working condition of the HEV and the stroke distance of the HEV, and performing control over the HEV under the energy consumption control mode. According to the invention, the most suitable energy consumption control mode can be automatically selected according to the stroke distance and the current real-time working condition, to control the proportion ratio of motor driving to engine driving, and thus emissions and driving consumption costs of users are greatly reduced. The invention also discloses an energy consumption mode selection system of the HEV.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an energy consumption mode selection method of a hybrid vehicle and an energy consumption mode selection system of a hybrid vehicle. Background technique [0002] The current plug-in hybrid electric vehicle (PHEV) is difficult to achieve the most suitable energy consumption under different road conditions and different journeys, and in many cases, it cannot make good use of the pure electric driving condition in the power consumption stage. For example, if it is predicted that the travel distance is relatively short, such as when the travel distance is about 30km in the morning and evening, if only the motor is used for auxiliary drive or power generation to make the engine work in a high-efficiency area, it is actually not good for the user. Economical, this is because within a journey of less than 50km, PHEV can reach the destination through pure electric drive, and there is n...
