In vehicle operation scenarios such as heavy-duty industrial and mining applications, trunk-line logistics, on-site construction projects, and new energy transportation, the AEBS (Active Emergency Braking System) has become a core standard for operational safety. While the industry primarily focuses on radar sensing and intelligent algorithms, the critical component that truly determines risk mitigation effectiveness, impacts driving experience, and ensures operational safety lies in the braking execution unit.
Identifying risks is fundamental, but effective vehicle control is paramount. Addressing industry challenges—including diverse braking systems across vehicle models, poor compatibility of traditional components, abrupt braking responses, lock-up issues during failures, and frequent secondary accidents—Henan Huhang Group (www.hu-hang.com) has pursued a path of domestic innovation. The company has developed three comprehensive line-control braking execution units: proportional motors, proportional hydraulic valves, and proportional pneumatic valves, covering all major vehicle braking systems (electric, hydraulic, and pneumatic). With precision linear braking technology, high-redundancy safety designs, and full operational adaptability, these solutions redefine AEBS safety standards and provide one-stop, highly reliable, domestically produced active safety offerings for automakers and corporate fleets.
1. Three Core Self-developed Products | Comprehensive coverage across all scenarios and operating conditions
(1) Line-controlled proportional motor: Non-invasive upgrade for all vehicle models
1. Precise Scenario Matching
Specifically designed for vehicles without pneumatic or hydraulic brake systems, this solution is fully compatible with ride-hailing vehicles, logistics trucks, electric in-plant transfer vehicles, electric forklifts, and small specialized electric machinery. It enables complete installation without damaging the original vehicle, requiring no pipeline modifications or structural alterations, and preserves the vehicle's factory performance, warranty coverage, and annual inspection eligibility—making it the simplest approach for vehicle safety upgrades.
2. Core Product Advantages
(1) Linear stepless braking ensures safer and smoother operation. It completely eliminates the drawback of traditional braking systems characterized by abrupt lock-up during emergency stops. Leveraging precise hierarchical control logic, it enables remote gradual deceleration, medium-range stable braking, and close-range forceful braking based on collision risk assessment. The braking process is linear and gentle, effectively preventing secondary impacts while balancing safety and operational comfort.
(2) Comprehensive fault safety with zero channel blockage risk. Equipped with an exclusive mechanical rebound mechanism, it automatically releases the braking state under extreme conditions such as complete vehicle power failure, system malfunctions, or signal abnormalities, ensuring dual safety redundancy.
(3) Comprehensive voltage compatibility with broader adaptability. Supports 12V/24V voltage platforms, accommodating complex electrical environments characterized by vehicle voltage fluctuations and frequent start-stop cycles within the field, ensuring stable power output and precise braking response.
(4) Military-grade durability with reduced maintenance costs. Featuring a high-strength wear-resistant alloy steel core and a fully sealed dust-and-waterproof корпус, it withstands harsh operating conditions such as mine dust, high port humidity, and frequent operations, demonstrating low failure rates and an extended service life that significantly reduces subsequent maintenance expenses for enterprises.
3. Core Differentiation Highlights
As a truly lossless braking solution for the industry, it addresses the challenge of integrating traditional brake actuators into new energy vehicles and specialized tube-free vehicles. Featuring a purely mechanical safety design that relies neither on electrical circuits nor software programs, its fault tolerance far exceeds that of conventional motor products, filling the market gap for lossless upgrades of AEBS systems in electric work vehicles.
（2）Electrically controlled proportional oil valve: A precision braking solution specifically designed for hydraulic construction machinery

Featuring standardized pneumatic interfaces, it enables rapid integration with existing vehicle systems and meets diverse heavy-load, high-risk operational requirements.
2. Core Product Advantages
(1) Dual-airway redundant design ensures full safety under heavy loads. It employs a dual-independent backup architecture: if one airway becomes blocked, leaks, or fails, the other can operate normally to maintain continuous braking regulation capability, completely eliminating the risk of brake failure in heavily loaded vehicles. This design is suitable for high-risk scenarios such as long downhill gradients and high-speed heavy-load operations in mining environments.
(2) Intelligent linear pressure regulation ensures more stable driving performance. Leveraging the AEBS risk gradient algorithm, it dynamically adjusts the intake pressure of the brake chambers to achieve smooth deceleration over long distances and powerful braking at close range, effectively addressing industry challenges such as high inertia in heavy-duty vehicles, abrupt braking, vehicle skidding or rollover, and tire lock-up.
(3) Excellent temperature tolerance across a wide range, enabling all-weather operation. With a rated working pressure of 0.8 MPa, it can operate in extreme environments ranging from-50°C to 85°C, demonstrating reliability under extreme mining conditions (severe cold or heat), open-air exposure, and frost exposure throughout the year and in all weather conditions.
