  • Patent number: 10316963
    Abstract: A pressure sensor rationality diagnostic for a dual clutch transmission includes a series of sensor tests. One such test includes charging an oil accumulator to a maximum pressure and storing the maximum pressure value. After performing a discharge pressure event and measuring the pressure value, the difference between the max pressure value and the discharge pressure value is calculated to determine if the difference is less than a predetermined threshold. If the difference is less than the predetermined threshold then at least one remedial action is performed which may include a driver alert or default charging mode. Additionally, similar sensor tests are performed to determine if faults exists and, if true, at least one remedial action is performed.

  • Publication number: 20130080029
    Abstract: A system includes a pedal override module that receives a pedal position from an accelerator pedal position sensor, receives a pedal pressure from an accelerator pedal pressure sensor, compares the pedal position to the pedal pressure, and selectively outputs a pedal override signal based on the comparison between the pedal position and the pedal pressure. A throttle position control module controls a position of a throttle based on the pedal position and the pedal override signal.
