Smarter Braking Solutions for Electric Travel Trailers

As the popularity of electric travel trailers continues to rise, so do the complexities associated with their braking systems. With the shift towards heavier loads and varying travel scenarios, traditional braking methods have faced challenges, particularly during emergency stops or long downhill descents. The interaction between tow vehicles and their trailers can become precarious, leading to issues such as pushing or pulling during braking incidents.

The Challenge of Conventional Braking

For electric trailers, conventional braking systems often lack coordination between the tow vehicle and the trailer. When brake performance is insufficient, trailers may push the towing vehicle forward, while excessive braking can pull the vehicle back, leading to potential loss of control. Additional factors like vehicle sway and fishtailing can further heighten safety risks during lane changes or sharp turns.

Moreover, electric travel trailers equipped with regenerative braking systems face the challenge of maintaining smooth and controlled deceleration as regenerative capabilities fluctuate. LEEKR Technology, a leading provider of intelligent chassis solutions based in China, addresses these challenges with its innovative DHB-P brake-by-wire system.

Introducing the DHB-P Brake-by-Wire System

LEEKR Technology's DHB-P system, which has entered mass production, marks a significant advancement in braking technology for electric travel trailers. By utilizing a decoupled hydraulic brake system, this technology offers enhanced responsiveness and coordination across various loads and road conditions.

How It Works

The DHB-P system adjusts hydraulic brake pressure dynamically in response to vehicle control commands. This adaptation improves the control between the trailer and the tow vehicle during braking, significantly reducing the risks associated with traditional systems. Furthermore, in situations where regenerative braking power diminishes, the DHB-P system provides hydraulic support to guarantee consistent deceleration, creating a smoother driving experience.

Designed specifically for original equipment manufacturers (OEMs), this brake-by-wire system boasts a compact structure and standardized interfaces, facilitating easier integration and installation across various vehicle platforms. To enhance flexibility, the system can also be configured to support an Electronic Parking Brake (EPB), catering to diverse project requirements.

Advanced Solutions for Evolving OEM Needs

Beyond the DHB-P, LEEKR Technology offers the IHB-P system, which integrates advanced features like Anti-lock Braking System (ABS) and Active Sway Control for superior safety and driving stability. This one-box integrated intelligent braking solution responds effectively to trailer sway, enhancing overall control while minimizing risks of fishtailing and rollover during critical driving conditions.

Market Potential and Future Developments

Data released by the RV Industry Association and the Caravan Industry Association showcases a booming market for towable RVs, suggesting a substantial demand for advanced braking technologies. In the U.S., deliveries reached approximately 306,000 units in 2025, while Australia had over 817,000 registered towable RVs at the beginning of that year.

Given LEEKR Technology's extensive experience in mass production and its established automotive-grade technology, the company is poised to revolutionize smart towable RVs. Their DHB-P brake-by-wire technology has already been deployed in multiple RV projects across North America, Australia, and China, hinting at promising growth and adoption in the industry.

Final Thoughts

As electric travel trailers become increasingly sophisticated, their braking systems must innovate to ensure safety and performance. LEEKR Technology's advancements in braking solutions not only promise improved safety for travelers but also set a standard for future developments in the industry.
