SMARK Electric develops a dual-MCU & VCU coordinated vehicle control system exclusively for three-wheel pedal-assist cargo tricycles, targeting urban last-mile delivery, rural freight and short-distance haulage scenarios. The complete system integrates dual main control MCU, vehicle control unit (VCU), speed sensing unit, torque sensor module, digital display terminal, dual-battery power supply architecture and drive motor assembly. Optional motor power covers 250W / 500W / 750W single & dual-motor configurations, with optional supporting accessories including generators, torque sensors and speed sensors.Adopting dual-chip collaborative control logic, the system delivers smooth startup under heavy loads and sustained power output on slopes, balancing easy riding and heavy load capacity. It fully adapts to multi-scenario freight demands such as urban commuting, agricultural market transportation and short-distance building material haulage, serving as an all-in-one intelligent electronic control solution for OEM matching and refitting upgrade of cargo tricycles.
