Description

technical field

[0001] The invention relates to the technical field of vehicle braking, in particular to a dual-motor braking actuator of an automobile decoupling distributed braking system. Background technique

[0002] The braking system is one of the important components of the automobile chassis, which is directly related to the comprehensive performance of the automobile and the safety of life and property. Although the traditional hydraulic and pneumatic braking systems can meet the requirements of the existing braking regulations, there are complex pipeline arrangements, relying on vacuum booster devices, slow braking response speed, non-active adjustment of braking torque, and difficulty in matching Other deficiencies such as system integration control are not suitable for the development requirements of automobiles, especially electric vehicle chassis integration control.

[0003] The electronically controlled braking system realizes the decoupling of the braking s...
