DTC C2A06: RH Resolver Circuit; DTC C2A07: LH Resolver Circuit [09/2014 - 01/2023]: Description
The TVD motor contains a TVD motor resolver sensor used to determine the position of the magnetic poles. It is necessary to know the position of the magnetic poles in order to precisely control the TVD motor.
The TVD motor resolver contains a stator equipped with 2 detection coils (S and C) and an excitation coil. When the elliptical shaped rotor turns, the gap between the stator and elliptical shaped rotor changes.
A fixed frequency AC current is sent though the excitation coil. The detection coils (S and C) output an AC waveform with a magnitude relative to the angle of the sensor rotor.
The TVD motor resolver detects the absolute position of the elliptical shaped rotor using the phase and amplitude of the waveform of the detection coils (S and C). Using the information provided by the TVD motor resolver, the ECU calculates the angle and rotational speed of the TVD motor.
The torque vectoring differential ECU assembly monitors the output signal of the TVD motor resolver to detect any malfunctions.
