Faced with the higher requirements imposed on core components of vehicle chassis by trends such as electrification, self-driving, and multi-unit transportation, the evolution of actuators toward high integration and precision has become inevitable.

Driven by electrification, self-driving, and multi-unit technologies, CDTL adopts distributed drive system. This system innovatively replaces the traditional mechanical differential with an electronic differential algorithm. By independently controlling the left and right wheels via dual-motors, control response times are achieved at the millisecond level.

For instance, in self-driving scenarios, the whole-vehicle's longitudinal and lateral control response speed and precision enabled by this distributed drive system far surpass what is achievable with conventional air brake-based control systems. The difference in response speed is equivalent to the gap between milliseconds and hundred milliseconds.

In the field of power trailers, EMB's strategic value proves particularly significant—serving as the "ultimate safety net" for Level 3+ Driving Automation. Its direct electrical signal control of braking modes fundamentally resolves traditional pneumatic system pain points: response lag, poor control precision, and high energy consumption. Simulation data confirms CDTL's EMB achieves millisecond-level response speed and accuracy, reducing brake trigger response time by 60% and time-to-maximum braking force by 40% compared to air brakes, delivering reliable safety assurance for heavy-haul transport and complex road conditions.

Benefiting from the highly integrated architecture of distributed drive axle and EMB (Electro-Mechanical Braking), the entire system occupies significantly reduced vehicle space. This space liberation unlocks valuable spatial resources for vehicle packaging. Specifically, across both electric and hydrogen platforms—particularly in critical component layouts like hydrogen tanks or battery packs—this spatial advantage provides greater design flexibility and possibilities, enabling more diversified solution options for customers.

Hardware-software decoupling, as a foundational characteristic in modern chassis systems, establishes a robust basis for system flexibility, upgradability, and independent development/maintenance, while serving as an essential prerequisite for meeting the complex control demands of future software-defined intelligent chassis.

CDTL's distributed drive axle + EMB system enable hardware-software decoupling, incorporating safety-critical software including IESS (Intelligent Electronic Stability System), EASR (Electric Anti-Slip Regulation), and DABS (Decoupled Anti-lock Braking System). It implements multi-layer safety redundancy strategies: distributed drive-brake coordination; multi-circuit independent braking; dual-source HV/LV backup; redundant power supply; and pure mechanical braking backup. For a fully-loaded dual-unit configuration, this technology reduces braking distance by approximately 10%. During emergency braking, EMB combined with distributed drive contains trailer yaw within 0.5 meters, significantly enhancing safety.

Currently, the Intelligent Road Train solution with CDTL's distributed drive system has entered the commercialization validation stage: Successful pilot operations in typical scenarios (Inner Mongolia, Qinghai in China), alongside functional verification of the first powered trailer unit in US.
