1. Technical Overview of EHB
Electro-Hydraulic Brake (EHB) is a core technology for intelligent vehicle chassis, replacing traditional mechanical connections with electronic signals to achieve precise brake control. Combining electronic control with hydraulic execution, EHB enhances reliability while enabling advanced smart features.
2. Core Advantages of EHB
- Performance Breakthroughs
Faster Response: Electronic signals act 3x quicker than hydraulic systems, reducing emergency braking distance by 15%.
Enhanced Energy Recovery: Synergy with regenerative braking boosts efficiency by 20-30%, extending EV range by 10%+.
High Load Capacity: Supports commercial vehicles with brake pressure >15 MPa.
Precision Control: Hydraulic pressure accuracy within ±0.5 MPa, ideal for L4 autonomous driving.
- Functional Flexibility
Decoupled Design: Physical separation between pedal and master cylinder allows customizable pedal feel (e.g., Sport/Comfort modes).

How EHB Works:
The Abooster (ACBS) Example
Signal Input
- The pedal displacement sensor detects driver input.
- Vehicle sensors (wheel speed, acceleration) feed real-time data to the ECU.
Electronic Execution
- The ECU calculates target braking force and drives a brushless motor.
- The motor actuates a worm gear and rack-and-pinion mechanism to push the master cylinder piston, generating hydraulic pressure.
Brake Decoupling
- A physical gap between the pedal rod and piston enables "feel simulation" and force decoupling.
- A pedal simulator provides programmable feedback (e.g., mimicking traditional vacuum booster feel).
Integrated Control
- Works with ABS/ESC for dynamic wheel-specific force distribution.
- Prioritizes regenerative braking in EVs, using hydraulics as backup

Global Readiness & Industry Applications
1.Leading Domestic Solution: Abooster (ACBS)
- Production Scale: Supplies automakers like BYD, NIO, and XPeng, with annual capacity exceeding 500,000 units.
- Certifications: Complies with EU ECE R13, China GB 21670, and ASIL-D safety standards.
- Cost Efficiency: Localized supply chain reduces costs by 30%, supporting small-batch orders (MOQ 50 units).
2.International Benchmarking
- Matches Bosch iBooster in performance but excels in 800V platform compatibility and localized algorithm optimization.
