  • Vehicle simulation system with software-in-the-loop bypass control
    Patent number: 8612192
    Abstract: A vehicle simulation system includes a first simulation model that when executed simulates a software ring along with other software of a vehicle module. The vehicle simulation system further includes a second simulation model of the software ring. A bypass switch that has a first state and a second state. A bypass switching module switches the bypass switch between the first simulation model and the second simulation model based on a bypass signal and a ring enabling signal. A simulation control module executes code of a vehicle simulation model including software in-the-loop (SIL) testing of a selected one of the first simulation model and the second simulation model based on state of the bypass switch.

  • Accumulator working volume management and adaptation
    Patent number: 8504263
    Abstract: A dual clutch transmission (DCT) control module includes a pressure determination module that determines a measured pre-charge pressure of an accumulator. A motor control module determines an actual pre-charge pressure based on the measured pre-charge pressure, stored previous pre-charge pressures, and ambient temperature, and controls a pump motor based on the actual pre-charge pressure.

  • PRE-SELECTION OF GEAR FOR A DOUBLE-CLUTCH TRANSMISSION
    Publication number: 20110218716
    Abstract: A method is provided for preselecting gear in a double-clutch transmission that includes, but is not limited to measuring at least two types of transmission speed of the double-clutch transmission, evaluating the at least two types of transmission speed, determining a next gear of the double-clutch transmission and preselecting the next gear.
