  • Patent number: 11927662
    Abstract: A method of evaluating current sensor measurements of an electric machine system includes acquiring a first current signal corresponding to a first measurement of a first phase current of a three phase electric current supply to an electric machine, and acquiring a second current signal corresponding to a second measurement of a second phase current of the three phase electric current supply. The method also includes determining a machine velocity, shifting the first current signal by a signal processing component to generate a shifted first current signal having a shifted phase, the signal processing component including a tuning parameter that is a function of the machine velocity, calculating an amplitude difference between the shifted first current signal and the second current signal, and determining a plausibility of the first measurement and the second measurement based on the difference.

  • Patent number: 11885245
    Abstract: An oil pressure actuated or torsion assisted phaser with a lock pin that has a position which shuts off communication between the advance and retard chambers and the front cam bearing and/or oil control valve, effectively acting as a shutoff valve and preventing leakage of oil from the advance and retard chambers. The prevention of leakage maintains oil in the phaser after engine shutdown. Additionally, by shutting off communication between the advance and retard chambers and the oil supply, the side load on the lock pin from the oil pressure torque on the rotor vanes during unlocking of the lock pin can be reduced or eliminated.
