Problems solved by technology

During the braking process of traditional fuel vehicles, friction consumes kinetic energy and converts kinetic energy into heat energy, which is wasted
Due to various factors such as emergency situations, drivers may brake frequently, which results in most of the energy wasted

Abstract

The invention discloses a regenerative braking force distribution optimization method for a pure electric vehicle, which comprises the following steps of: when the vehicle is braked, judging the friction force borne by a current tire in real time, dividing the braking process into different time periods including a low time period, a middle time period and a high time period according to the change of the friction force, and executing a preset distribution strategy in the corresponding time period. According to the regenerative braking force distribution optimization method for the pure electric vehicle, based on a time-sharing friction force distribution strategy, the braking force demand value of each tire point in the braking process can be collected, the energy storage system can be guided to reasonably distribute the power supply time and the power supply amount, and the effect of optimizing braking force distribution is achieved.

Description

technical field [0001] The invention relates to the related technical field of new energy vehicles, in particular to a method for optimizing regenerative braking force distribution of pure electric vehicles based on a multi-objective genetic algorithm. Background technique [0002] As a means of transportation, automobiles play a very important role in our daily life and provide great convenience for people's daily life. [0003] Compared with traditional fuel vehicles, pure electric vehicles use permanent magnet motors instead of internal combustion engines to generate power through electricity. In addition, pure electric vehicles have the characteristics of braking energy regeneration feedback and precise adjustment of braking torque. During the braking process of traditional fuel vehicles, kinetic energy is consumed due to friction, and the kinetic energy is converted into heat energy and wasted. Due to various factors, such as emergency situations, drivers may brake fr...
