Title:
ELECTRO-HYDRAULIC HYBRID BRAKING SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/248927
Kind Code:
A1
Abstract:
Disclosed is an electro-hydraulic hybrid braking system for a vehicle, the system comprising wheel-end braking modules (1), a hydraulic control module (2), a first electronic control module (3) and a second electronic control module (4), wherein each of the wheel-end braking modules (1) comprises a hydraulic piston (10), an electric motor (8), and a speed-reducing transmission mechanism (9) which is used for converting a rotary motion from the electric motor (8) into a linear motion for driving the hydraulic piston (10) or a brake friction plate (12) to move forwards; four wheel-end braking modules (1) are provided; the hydraulic piston (10) is movably arranged, and can move forwards by means of brake hydraulic pressure; and the electric motor (8) of the wheel-end braking module (1) is controlled by the first electronic control module (3) and/or the second electronic control module (4). The electro-hydraulic hybrid braking system for a vehicle is applied to an intelligent driving vehicle braking system. By means of providing the four wheel-end braking modules (1) each having the electric motor (8) and hydraulic control, when the hydraulic control system or the electric motor control system fails such that a braking force cannot be automatically generated, the other system can automatically generate a braking force to slow down the vehicle, thereby improving driving safety and meeting the braking requirement of intelligent driving.
