Driving habit recognition method, system and equipment for electric automobile and storage medium

Abstract

The invention discloses a driving habit recognition method, system and equipment for an electric automobile and a storage medium. The driving habit recognition method for the electric automobile comprises the steps that S100, a history driving habit score value of each unit time section before a unit time section of the current time is obtained by using a preset time length as a unit time section;and iteration is carried out on the history driving habit score values according to an iteration strategy to obtain a current driving habit score value of the current time, wherein the history driving habit score value is obtained according to a road condition type of a running road and a sliding coefficient in the unit time section; and S200, the electric automobile comprises an instrument; andthe current driving habit score value is displayed on the instrument.

Description

technical field [0001] The present invention relates to the field of electric vehicles, and more specifically, relates to a driving habit recognition method, system, device and storage medium for electric vehicles. Background technique [0002] The development and promotion of new energy vehicles is an important measure to solve the current air pollution and energy crisis. However, limited by the development of battery technology, electric vehicles still have the problem of short mileage, which is easy to cause mileage anxiety for drivers. Using the control system, during the deceleration process, the kinetic energy of the vehicle can be effectively converted into electric energy to recover more energy, or to slide for a longer distance, which can effectively reduce the fuel consumption rate (kilometer power consumption). [0003] The so-called braking energy recovery is to convert a part of the kinetic energy of the vehicle into other forms of energy and store it in the pro...

Problems solved by technology

[0004] However, the deceleration process depends on the driver's operation. Impatient drivers prefer to accelerate quickly and step on the brakes, which leads to premature intervention of the mechanical brake, and most of the kinetic energy is lost through the mechanical brake system; moderate drivers prefer to accelerate more slowly. During coasting, if the electrical feedback during the coasting process is large (the feedback torque is large), in the process of converting kinetic energy into electrical energy, and then converting electrical energy into kinetic energy, there will be a certain loss of charging and discharging efficiency
