Remove the brake pipeline and brake fluid necessary for the traditional electronic hydraulic braking system, and innovatively integrate the core components such as mechanical brake, electronic hardware, ball screw, planetary gear, permanent magnet synchronous motor and so on.
the efficiency of the new braking system is much better than that of the existing electronic hydraulic braking system.
Completely put an end to the failure risk caused by brake fluid leakage, based on highly robust clamping force triple fusion control technology, eliminate the use of force sensor, greatly reduce the system cost, more competitive than the existing brake products.
the expandable software interface is conducive to the self-research and development of the whole vehicle factory, and cooperate with the steering algorithm to improve the boundary of vehicle movement.
Future prospects: in the development process of the automobile industry, the wire-controlled chassis is the intersection of intelligent and electrified tracks, the electronic and electrical architecture develops from distributed to centralized, and the actuator develops from centralized to distributed.
From the general trend, electromechanical is gradually replacing hydraulic.
In the horizontal and vertical three-way control of on-line chassis, the technical difficulty of wire-controlled braking is the highest.
As an advanced on-line braking technology, EMB braking system is considered to be the future development direction of on-line braking technology because of its fast response, accurate control, environment-friendly and high compatibility with intelligent vehicles.
With the continuous development of automobile electrification and intelligence, the EMB system is expected to gradually replace the traditional hydraulic braking system.
It has obvious advantages in safety, response speed and energy recovery.
The brake is driven directly by the motor without hydraulic piping and brake fluid, thus reducing the complexity and environmental risk of the system.
The integrated and modular design of the system will help to simplify the automobile braking system and improve its reliability and maintainability.
At the same time, with the development of self-driving technology, the EMB system will be better integrated with other electronic control systems of the vehicle, support cross-domain integration, and improve the intelligent level of the whole vehicle.
It is expected that by 2025, the market scale of on-line braking system will expand significantly.
With the progress of technology and the reduction of cost, the application of EMB system will be more extensive.
It is expected that EMB technology will achieve wider market penetration in the next few years.
Parts companies, including coordinate systems, will gradually promote the application of EMB in the whole vehicle together with the whole vehicle factory.
