Abstract: A launch control system launches a vehicle from a slowed speed or stopped condition, to an accelerated speed. The system is activated by operating a switch while the vehicle is stopped. An acceleration pedal is depressed while an up shifter paddle and down shifter paddle are being held in a shifting position. The system launches the vehicle when the up shifter paddle and the down shifter paddle are simultaneously moved to a non-shifting position. The system automatically switches gears during the launch so as to increase the speed of the vehicle. The system is activated until the speed of the vehicle reaches a speed associated with the amount the accelerated pedal is depressed. The system may further inhibit yaw rotation of the vehicle during launch by moderating a rotation rate of the vehicle engine.

Abstract: A tachometer display system and method is provided. In one embodiment, a tachometer display system includes a tachometer for indicating a plurality of engine speeds. The tachometer is configured to display a current engine speed based on a current gear ratio of a manual transmission. At least two synchronous shift point indicators are displayed at variable locations near the tachometer. Each synchronous shift point indicator is displayed near a location on the tachometer associated with an engine speed that corresponds to a transmission input shaft speed for a downshifted gear ratio of the manual transmission from the current gear ratio.

Abstract: A method of controlling an engine in a motor vehicle includes opening a throttle to an increased angle when conditions for fuel cut cycling are met. More specifically, when cruise control is on, the motor vehicle is moving downhill, and the current speed drops below a target speed, the engine control unit may choose to increase the angle of the throttle while maintaining fuel cut. Under other interrupting events, the engine control unit may choose to resume fueling control or reduce the throttle angle.

Abstract: An automatic transmission controller system and method are disclosed. In particular, disclosed is a system and method for controlling solenoid pressure control valves associated with an automatic transmission. The automatic transmission controller system comprises a controller which is configured to receive one or more electrical signal inputs for attributing each solenoid pressure control valve with one of a set of I-P calibration curves.

Abstract: A system and method for overrun prevention is disclosed. Overrun of a one-way clutch may be prevented by determining a current torque value. When a current torque value approaches a negative value, a shift to a gear without a one-way clutch may be performed. Driving control may be increased by shifting from a gear associated with a one-way clutch when a current torque value approaches a negative value or another shifting parameter determines a shift is necessary.

Abstract: A control system and method for an internal combustion engine includes an intake manifold for directing airflow to a plurality of cylinders of the engine and an electronically controlled throttle valve disposed within the intake manifold for regulating airflow into the engine. An engine retard control determination module determines whether retard control of the engine is disabled. A throttle control module communicates with the electronically controlled throttle valve and modifies a throttle return trigger point during a transmission upshift when the retard control determination module determines that retard control of the engine is disabled.

Abstract: A torque converter lockup clutch control system is provided for an associated automatic transmission. The system includes a torque converter having an impeller operatively coupled to an associated internal combustion engine and a turbine operatively coupled to an input shaft of the associated automatic transmission. A lockup clutch is disposed within the torque converter for selectively locking the impeller to the turbine. A pressure regulator is operatively coupled to the torque converter for adjusting the pressure of a working fluid to at least one shift clutch of the associated automatic transmission in response to a speed differential between the impeller and turbine of the torque converter. A shift clutch slip detector is provided for detecting a slip condition of the at least one shift clutch of the associated automatic transmission and outputs a slip value.
