Abstract: A transmission includes sensors positioned adjacent respective pairs of magnetized bands on a shaft of the transmission for detecting magnetic flux emanating from the bands in response to torque on the shaft. The transmission further includes an electronics interface assembly configured to respectively provide drive signals to the sensors and to receive from the sensors, in response to the drive signals, output signals indicative of the torque on the shaft as detected by the sensors.

Abstract: A system for improving operation of an engine having a particulate matter sensor is presented. The system may be used to improve engine operation during cold starts especially under conditions where water vapor or entrained water droplets are present in vehicle exhaust gases. In one embodiment, particulate sensor degradation is indicated in response to an output of said particulate matter sensor staying below a threshold as engine temperature increases past the dewpoint temperature.

Abstract: Systems, methods, and computer-readable media are disclosed for a pulse switched high side driver for vehicle sensor. An example method may include switching a transistor of a vehicle circuit to connect a first resistor to a vehicle sensor for a first time period in which exhaust gas temperature values of the vehicle are within a first range of exhaust gas temperatures values. The example method may also include switching, by providing a pulse-width modulation (PWM) signal with an on signal value, the transistor to connect a second resistor to a vehicle sensor for a second period of time in which exhaust gas temperature values of the vehicle are within a second range of exhaust gas temperatures values that are greater than the first range of exhaust gas temperature values, wherein the second resistor and vehicle sensor are also included in the vehicle circuit, wherein the second resistor is in parallel with a first resistor and connected between the transistor and the vehicle sensor. The example method may also include switching, by providing a pulse-width modulation (PWM) signal with an off signal value, the transistor to disconnect the second resistor from the vehicle sensor for a third period of time, the third period of time being greater than the second period of time. The example method may also include reading, using an analog to digital converter (ADC) an output of the vehicle sensor during or after the first period of time.
