Problems solved by technology

At present, most of the methods and systems for energy consumption monitoring and optimization of electric vehicles collect vehicle operation information for a period of time to evaluate energy consumption. This method cannot perform dynamic analysis based on the driver’s real-time driving habits, and the accuracy of monitoring and evaluation results is low. Low

Embodiment Construction

[0059] Such as Figure 5 As shown, a pure electric vehicle energy consumption monitoring optimization method, the method includes the following steps in order:

[0060] (1) Set the target location that the vehicle needs to arrive at. After the vehicle is started, it starts to collect vehicle operation information. The vehicle operation information includes vehicle status information and vehicle component status information;

[0061] (2) Determine the actual road conditions from the current vehicle location to the target location, and simulate the actual road condition information;

[0062] (3) When the number of driving cycles i ≥ 1, the energy consumption evaluation starts, and after that, every time the vehicle completes an energy consumption evaluation cycle T E , all perform an energy consumption assessment, the energy consumption assessment includes evaluating the driver's driving habits and the energy consumption rate under the i-1th energy consumption assessment cycle;...

Abstract

The invention relates to a method for monitoring and optimizing the energy consumption of a pure electric vehicle, comprising: setting a target location that the vehicle needs to arrive at, and starting to collect vehicle operation information after the vehicle is started; Carry out simulation; start energy consumption evaluation when the number of driving cycles i≥1; calculate and obtain real-time energy consumption efficiency in the current energy consumption evaluation cycle, and calculate the real-time energy consumption efficiency E i and the energy consumption rate E under the i-1th energy consumption assessment cycle i‑1 Displayed on the on-board instrument; give optimization suggestions for driving behavior; compare the remaining power of the battery with the remaining required power, and give a reminder whether the driver can reach the target location normally. The invention also discloses a pure electric vehicle energy consumption monitoring and optimization system. The present invention can not only accurately provide the current energy consumption situation to the driver, but also provide suggestions for the driver's driving behavior, so as to realize energy saving and consumption reduction of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicle monitoring and energy saving optimization, in particular to a method and system for monitoring and optimizing energy consumption of pure electric vehicles. Background technique [0002] With the gradual aggravation of the energy crisis and environmental pollution, electric vehicles, as a strategic industry, have attracted more and more attention for their use of clean energy. The economics of electric vehicles has always been the focus. Due to the existence of battery core technology bottlenecks and the complexity of the actual road conditions, the driver cannot grasp the real-time consumption of battery energy. mileage anxiety". [0003] In addition to the complex actual road conditions, the driver's own driving behavior will also cause an increase in energy consumption. For example, bad driving behaviors such as continuous high speed and frequent rapid speed increase will aggravate the...
