摘要： An apparatus including a rotating member, a resolver and a mounting structure. The resolver includes a resolver stator and a resolver rotor fixedly mounted on the rotating member via a mounting structure. The mounting structure has a low magnetic relative permeability and isolates the resolver rotor from the rotating member by preventing direct contact between the rotating member and the resolver rotor. The disclosed apparatus may be an electric machine having a rotor fixed to the rotating member and be suitable for use in a hybrid vehicle. The mounting structure advantageously has a relative permeability of no greater than about 2 and may be formed out of stainless steel material. The rotating member may be a rotor hub formed out of steel material having a relative permeability of at least about 50.

摘要： A diagnostic system and method for a vehicle with a starter-based stop-start system. At least one diagnostic check is performed before stopping the engine as a function of the stop-start system. Both diagnostic checks may be performed. If a diagnostic check indicates a failure of the starter motor or solenoid, operation of the stop-start system is suspended. The system utilizes a sensor to determine if the starter shaft is rotating when the shaft is in a position wherein a gear on the shaft is disengaged. Operability of the starter motor is checked by energizing and then de-energizing the motor without engaging the gear and determining if the shaft rotates. Operability of the solenoid is checked by sensing the rotation of the starter shaft and then energizing the solenoid to move the shaft into a position where the sensor cannot detect rotation of the shaft.
