摘要： A method controls a transmission of a vehicle. The vehicle includes an engine for driving wheels, a transmission coupled between the engine and the wheels. The transmission automatically selects driving gear positions enabling the vehicle to move in a forward or reverse direction. The method provides gear shift structure associated with the transmission. While the transmission is in a presently selected gear position to move the vehicle in the forward or reverse direction, the gear shift structure is permitted to be initially manually engaged and moved to a first position to cause one gear change from the presently selected gear position. While the gear shift structure is in the first position, the gear shift structure is permitted to be manually engaged again to cause a gear change from the one gear change position. The gear change will provide optimum up-shift for performance or, when down-shifting, will provide maximum gear braking.

摘要： An improved surge suppression control for a motor vehicle drivetrain detects and suppresses drivetrain oscillation in a predetermined range of frequencies centered on an estimate of the natural frequency of the drivetrain. The drivetrain natural frequency is determined based on the current speed ratio of the vehicle transmission and empirically determined vehicle characteristics, and is used to define the center frequency of a band-pass filter responsive to engine speed. The filter output represents the AC component of the engine speed in a range of frequencies centered on the driveline natural frequency, and such component is differentiated to form an acceleration component in phase synchronism with the torque causing the detected resonance. An electric machine mechanically coupled to the engine is energized in accordance with the inverse of the acceleration component to actively cancel the detected resonance whenever the acceleration component exceeds a noise threshold that also is adjusted based on the estimated natural frequency of the drivetrain.
