Abstract

The invention provides a power quality control method of a hybrid power electric vehicle. The power quality control method comprises the following steps of: the step 1, on-line receiving or distinguishing the operation information of a hybrid power system, the status information of the vehicle, and the operation information of a driver; the step 2, executing the instruction torque and the instruction power control of the driver; the step 3, executing power and energy management control on the vehicle, and computing a primary control instruction to power sources and judging the switching of operational modes; the step 4, executing power quality active control based on the prediction and feedback mode of the shock degree of the vehicle; the step 5, switching power quality active control based on the pre-adjust and feedback modes of power source rotational speed; the step 6, executing self-learning on the actively acquired power source dynamic response based on the characteristic working conditions; and the step 7, outputting a control instruction to each power source. According to the power quality control method disclosed by the invention, the real-time control of the power quality of the hybrid power electric vehicle is realized, and the method has the characteristics of being good in power quality, and easy to realize for actual vehicles.

Description

technical field

[0001] The invention relates to a hybrid electric vehicle control technology, in particular to a power quality control method for a hybrid electric vehicle. Background technique

[0002] Hybrid electric vehicles (including plug-in hybrid electric vehicles) have become the focus and hotspot of global development. They are operated by a variety of energy sources and heterogeneous power sources through electromechanical coupling under the control of a control system. Due to the different power output characteristics of each heterogeneous power source, the power quality of the vehicle is deteriorated, the driving comfort is affected, and the reliability of the vehicle is adversely affected. Therefore, it is necessary to effectively control the power quality of HEVs.

[0003] At present, in the control of the power quality of the hybrid electric vehicle, a ramp function is generally used to suppress the sudden change of the vehicle driving torque, thereby suppres...
