HYBRID TRANSMISSION MOTOR CONTROL FOR POWER-HOP AND ENGINE MOUNT LOAD REDUCTION USING TORSIONAL VIBRATION RESONANCE MODE

A control system for a hybrid transmission of a vehicle, the hybrid transmission having first and second electric motors, comprises a motor speed sensor configured to measure a rotational speed of the first electric motor and a controller. The controller is configured to determine a first difference between a first measured speed and a first expected speed of the first electric motor, when the first difference exceeds a speed threshold indicative of tire slippage, temporarily adjust a torque output of the second electric motor to compensate for an oscillation generated by the first electric motor, after controlling the second electric motor to temporarily adjust its torque output, determine a second difference between a second measured speed and a second expected speed of the first electric motor, and when the second difference does not exceed the speed threshold, control the second electric motor based on a driver torque request.
