Brake energy recycling device and method for controlling same

Abstract

The invention discloses a brake energy recycling device and a method for controlling the same. The brake energy recycling device comprises a brake maneuvering mechanism, a brake pedal travel simulatorand a hydraulic adjusting unit. A front-cavity liquid outlet A of a brake master cylinder in the brake maneuvering mechanism is connected with a liquid inlet D of the hydraulic adjusting unit by a brake pipeline, a rear-cavity liquid outlet B of the brake master cylinder in the brake maneuvering mechanism is connected with a liquid inlet E of the hydraulic adjusting unit by a brake pipeline, andan interface C of the brake pedal travel simulator 8 is connected with the liquid inlet D of the hydraulic adjusting unit by a brake pipeline. The brake energy recycling device and the method have theadvantage that the problems of incapability of meeting performance requirements on existing hydraulic adjusting units by the ability of existing products, complicated structures, high control difficulty and inconsistency of pedal feel and the traditional vehicles in the prior art can be solved by the aid of the brake energy recycling device and the method.

Description

technical field [0001] The invention relates to a braking energy recovery system for a hybrid vehicle and a pure electric vehicle, more precisely, the invention relates to a braking energy recovery device and a control method thereof. Background technique [0002] In the context of the increasing shortage of non-renewable energy in the world, major manufacturers have introduced braking energy recovery technology in order to improve the mileage of new energy vehicles and reduce energy consumption. Braking energy recovery is an important way for hybrid electric vehicles and pure electric vehicles to achieve energy saving and emission reduction. During the braking process, it is necessary to ensure the safety of the brakes, ensure the feeling of the pedal, reasonably distribute the braking force, and accurately control the braking force. The existing braking system cannot meet these requirements, so it is necessary to improve the original braking system to realize the braking ...
