Abstract

The invention relates to a decoupling intelligent braking system and a braking torque control method thereof. The decoupling intelligent braking system comprises a pedal assembly, an ECU for logic control, a displacement sensor and a liquid storage tank, the liquid storage tank is connected with a first main cylinder cavity, a second main cylinder cavity, a servo system and a pedal simulator, and an outlet of the first main cylinder cavity is provided with a first isolation valve; a pedal simulator valve and a first one-way valve are arranged between the outlet of the first cavity of the main cylinder and the first isolation valve, and the outlets of the pedal simulator valve and the first one-way valve are connected with the inlet of the pedal simulator; a second isolation valve and a main cylinder pressure sensor are arranged at an outlet of the main cylinder second cavity; an outlet of the servo system is provided with a first control valve and a second control valve. The first control valve and the second control valve are connected with the ESC / ABS; the pedal assembly is connected with a first cavity of the main cylinder through a push rod; the invention further relates to a braking torque control method of the decoupling intelligent braking system, the method is divided into four different modes, the decoupling intelligent braking system has an active pressurization function, and the problem of power-assisted faults of the braking system can be solved.

Description

technical field [0001] The invention relates to the technical field of vehicle braking systems, in particular to a decoupling intelligent braking system and a braking torque control method thereof. Background technique [0002] At present, with the rapid promotion of new energy vehicles and the continuous advancement of technology in the field of intelligent driving, the requirements for the intelligent driving execution system-braking system are constantly increasing. Due to the limitation of the mechanical structure of the non-decoupled braking system, it cannot support advanced automatic driving. boost function. [0003] In order to overcome the above-mentioned shortcomings of non-decoupled braking systems, decoupled braking systems have been gradually introduced to the market. The current market decoupling solution mainly detects the pedal displacement signal and uses the electronic booster to generate a pressure source to brake the vehicle. [0004] However, for the b...
