Do you feel safer towing a trailer equipped with modern automated braking and stability technology?
Leekr Technology has launched mass production of its DHB-P brake-by-wire system, designed to enhance braking control in electric travel trailers. This system is currently being integrated into RV projects across North America, Australia, and China to improve safety during deceleration.
Why it matters
The system addresses common trailer handling issues like sway and fishtailing by automatically generating hydraulic brake pressure. This technology aims to provide consistent stopping power for electric towable RVs as they become more common in the market.
The DHB-P system supports 306,000 U.S. annual RV shipments and is intended for a massive existing market, including 817,000 registered towable RVs in Australia alone. Exact rollout timelines for individual trailer models remain dependent on manufacturer schedules.
The players
Leekr Technology
A developer of braking and control systems that specializes in brake-by-wire technologies for the electric vehicle industry.
The details
The DHB-P system utilizes full hydraulic decoupling to adjust brake pressure based on real-time commands from the trailer's control system. When the vehicle detects a decrease in regenerative braking, the system compensates by adding hydraulic force to maintain steady deceleration. It also integrates with electronic stability control to proactively manage sway and prevent trailer pushing or pulling during travel.
Timeline
January 2025: Australia reported 817,000 registered towable RVs.
2025: U.S. towable RV shipments totaled 306,000 units.
October 30, 2026: Leekr Technology announced the start of mass production.
The Home Front
The adoption of electronic brake-by-wire systems marks a major transition in trailer safety technology as towable RVs become increasingly electrified. This development moves beyond traditional mechanical braking to integrate active sway control directly into the trailer's architecture.
If you are shopping for a new electric travel trailer, ask the dealer about the inclusion of integrated electronic stability and sway control systems. Verify if your current trailer's towing system is compatible with the latest brake-by-wire technology before planning any major upgrades.
The takeaway
New brake-by-wire systems offer improved trailer stability by automating hydraulic pressure during deceleration. Keep track of your RV manufacturer's specifications for braking upgrades to ensure your towable trailer is equipped with the latest stability technology.
