A dual-motor drive assembly comprising a housing, a shaft mounted to the housing, a first gear connected to the shaft, a first motor lane comprising motor an output, a motor drive-stage driving the first motor in response to a torque demand and applying a torque to the first gear, and a first position sensor generating a first motor position signal, a second motor lane comprising a motor having an output, a motor drive-stage driving the second motor in response to a torque demand, and applying a torque to the first gear, and a second position sensor generating a second motor signal, the two motor outputs engaging with the first gear such that both motors' torque output is applied to the shaft. A processor generates an estimate of the first motor position using the signal from the second sensor and the effect of any backlash in the assembly, and cross-checks first signal against the estimate to determine if one of the motor position sensors is faulty.
