DTC 261

DTC P0A92/261 HYBRID GENERATOR PERFORMANCE

CIRCUIT DESCRIPTION

DTC Detection Condition:

When three-phase alternating current flows through the three-phase windings of the stator coil, a rotating magnetic field is generated in the motor. The system controls the rotating magnetic field in accordance with the rotating position and speed of the rotor. As a result, the permanent magnets provided on the rotor are pulled in the rotating direction, which cause the generation of torque.

The generated torque is practically proportionate to the amount of current. Therefore, the system controls the speed of the motor by regulating the frequency of the alternating current. Furthermore, the system properly controls the rotating magnetic field and the angle of the rotor magnets in order to generate high torque in an efficient manner, even at high speeds.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

Component Operating Range:

The HV control ECU monitors the hybrid vehicle generator (MG1). If the HV control ECU detects a reduction in the magnetic force of the MG1 or an in-phase short, it interprets this as a MG1 failure. The HV control ECU then illuminates the MIL and sets a DTC.
