  • Patent number: 11320340
    Abstract: A control device performs deterioration diagnosis of a gas sensor including a pump cell and a sensor cell. The control device includes a control unit, a determination value acquisition unit, a diagnosis unit, and a correction unit. The control unit temporarily reduces the oxygen removal capability of the pump cell. The determination value acquisition unit acquires an output ratio of the sensor cell based on an output value of the sensor cell in a state where the oxygen removal capability of the pump cell is temporarily reduced. The diagnosis unit performs deterioration diagnosis of the gas sensor by comparing the output ratio with a determination threshold. The correction unit sets a correction coefficient based on an atmospheric pressure and an oxygen concentration, and also corrects the output ratio using the correction coefficient.

  • Patent number: 11307105
    Abstract: A torque meter shaft that includes a hollow tube, a ring with ring tabs, the ring enveloping the hollow tube, a shaft with shaft tabs and a deformable section, the shaft disposed within the hollow tube such that the ring tabs and the shaft tabs correspond forming an inter-locking non-contact fit, and a first spline coupling and a second spline coupling. The first spline coupling communicates with an engine such that torque from the engine is transferred to the deformable section and elastically deforms when torque is applied to the first spline coupling and the shaft tabs change radial position relative to the position of the ring tabs such that relative change in torque can be measured, and when torque results in creating a shaft deformation that passes the material yield point, the ring tabs and shaft tabs contact each other, and the ring tabs are pushed back into a new position that compensates for the shaft deformation allowing the engine to maintain its full power capacity.

    Abstract: Aspects of this disclosure relate to a magnetic sensor system for measuring any desired combination of measuring torque, rotation angle, and turn count of a shaft. The shaft may include two portions connected by a torsion element. The system can measure rotation angle using a magnetic target coupled to the shaft that produces a magnetic field that varies as a function of rotation angle. The system can measure torque applied to the shaft by measuring the difference in rotation angles between the two portions of the shaft and factoring in a torsion coefficient. The system can track a turn count of the shaft using a multi-turn sensor. The magnetic sensor system may be part of an electric power assisted steering (EPAS) system.
