Dual-Motor Differential Torque Control With Split ECUs

The patent divides the control system into two independent control units, with each control unit controlling one electric motor. Each control unit receives sensor signals and calculates assigned torques independently, avoiding the rotational interference that occurs when a single control unit manages both motors through a mechanical differential mechanism. This segmentation of control functions eliminates the vibration and torque application problems while maintaining the ability to apply torque differences to the wheels.

The patent segments the control configuration into two independent control units, each receiving sensor signals and calculating assigned torques independently. This segmentation maintains relatively simple control configurations at each unit while achieving precise torque control by avoiding the rotational interference that plagues single-ECU differential mechanisms. Each control unit operates independently to ensure precise torque application to its respective motor.

The patent eliminates the need for a differential mechanism with amplifying function by segmenting the control into two independent control units. Each control unit independently controls one motor and applies the required torque directly, achieving large torque differences without the rotational interference and precision problems associated with mechanical differential mechanisms. This approach maintains the ability to generate large torque differences while ensuring precise torque application.
