摘要： A method of operating a vehicle includes, responsive to a command to launch the vehicle and while the vehicle is in a first gear, determining, at a controller, a feedforward component including a target engine torque and a target bypass clutch torque, and a feedback component that is based on an error between the target converter slip and a measured converter slip and between the target wheel torque and a measured wheel torque. The method further includes changing a commanded engine torque and a commanded bypass clutch torque based on the feedforward component and the feedback component.

摘要： A vehicle includes an engine and driven wheels each having an associated friction brake. A brake pedal is operable to engage the friction brakes. The vehicle includes a transmission having an input shaft driveably connected to the engine, an output element driveably connected to the driven wheels, and a gear mechanism adapted to establish at least one torque flow path between the input shaft and the output element. The transmission further includes a shift element that interrupts the torque flow path when disengaged. A gear selector is disposed in the passenger cabin and includes at least one forward-drive position, a reverse position, and a neutral position. At least one vehicle controller is configured to, in response to the gear selector being in the forward-drive position, a speed of the vehicle being zero, the vehicle being within a first predefined distance of a stoplight, and the brake pedal being depressed, disengage the shift element to put the transmission in neutral idle.

摘要： A hybrid vehicle includes an electric motor and a combustion engine. A K0 clutch couples the combustion engine to a drivetrain of the vehicle. A control module of the vehicle calculates a torque to be applied by the motor to the K0 clutch when initiating engagement of the combustion engine to the drivetrain. The control module calculates two separate torque lead values by two separate methods and calculates the torque by combining the two torque lead values.

摘要： A vehicle includes an engine with an associated engine-speed sensor, and wheels each having a respective wheel-speed sensor. The vehicle also includes a continuously variable transmission (CVT) coupled to the engine and configured to operate at variable input-to-output ratios. At least one controller is programmed to reduce the operating ratio of the CVT in response to the engine-speed sensor indicating the engine is operating at idle speed and the wheel-speed sensor indicating the velocity is approximately zero. This provides less noise, vibration and harshness in the vehicle due to the reduced ratio that is possible during conditions in which a vehicle launch in that reduced ratio may not be acceptable.

摘要： A vehicle includes a transmission and a controller. The controller is configured to receive a torque request, calculate an SFC for satisfying the torque request in an initial gear and in an alternate gear, and command the transmission to shift from the initial gear into the alternate gear in response to the calculated SFC for satisfying the torque request in the alternate gear being less than the calculated SFC for satisfying the torque request in the initial gear.
