Active damping system and method of distributed electric vehicle

Abstract

The invention discloses an active damping system of a distributed electric vehicle. The system is applied to an automobile control system. The active damping system comprises information collection devices, an analysis device and damping devices. The information collection devices are correspondingly arranged in front of all tires of the distributed electric vehicle one to one and used for acquiring road surface information in front of all the tires; the analysis device is used for generating vibration information corresponding to all the tires one to one based on the road surface information;the damping devices are correspondingly arranged between all the tires and suspension racks of the distributed electric vehicle one to one and used for controlling the tires corresponding to the vibration information to conduct active damping on the road surface based on the vibration information. The invention further discloses an active damping method of the distributed electric vehicle. According to the system and method, the manufacturing and application cost of the electric vehicle is lowered, the control complexity of the electric vehicle is lowered, the stability of the electric vehicle is improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an active damping system and an active damping method of a distributed electric vehicle. Background technique [0002] As one of the means of travel for modern people, cars have become an indispensable and important part of people's lives. In the era of gasoline-powered vehicles, the driving method of the car is mainly driven by the centralized driving method, that is, the output of the driving force is concentrated through an engine, and the driving force is distributed to the four tires of the car through a transmission and other devices. [0003] However, with the continuous development of storage battery technology, it has become a reality to provide driving force for vehicles by carrying storage batteries, thus electric vehicles have emerged. Since the driving force of an electric vehicle mainly comes from the battery, the motor is driven to rotate by outputting electric en...

Problems solved by technology

[0005] The purpose of the present invention is to provide an active damping system and active damping method for distributed electric vehicles in order to overcome the technical problems of poor damping effect and high damping cost in the prior art. According to the road conditions in front of each tire, each tire is controlled to perform corresponding active damping operations based on the road conditions in front of each tire, so as to achieve a low-cost, high-precision damping effect
