Abstract: A vehicle includes an internal combustion engine, brake actuators configured to slow the vehicle in response to braking commands, and a transmission. The transmission includes a plurality of gear sets each having a plurality of nodes, an input member that is continuously connected to the engine and to a node of one of the gear sets, a reverse clutch, a binary clutch assembly, and a controller. The binary clutch assembly is connected at least to the same gear set as the input member, and is applied with the reverse clutch when entering a reverse gear state. The controller executes a method to transmit the braking commands to the brake actuators in response to a requested garage shift into a reverse gear state when the vehicle is rolling above a calibrated speed threshold, and thereby slows the vehicle until a calibrated target slip is achieved across the binary clutch assembly.

Abstract: A target ratio module selectively determines a target ratio of transmission input shaft speed to transmission output shaft speed independently of an accelerator pedal position and as a function of a vehicle speed and a driver axle torque request. A first pulley valve control module controls opening of a first valve based on the target ratio. The first valve controls transmission fluid flow to a first pulley actuator. The first pulley actuator is coupled to the transmission input shaft of a continuously variable transmission (CVT) and expands and contracts based on transmission fluid pressure. A second pulley valve control module controls opening of a second valve based on the target ratio. The second valve controls transmission fluid flow to a second pulley actuator. The second pulley actuator is coupled to the transmission output shaft of the CVT and expands and contracts based on transmission fluid pressure.

Abstract: A vehicle includes an engine, drive wheels, a continuously variable transmission (CVT), and a controller. The CVT includes an input member connected to the engine, an output member delivering output torque to the wheels, and a variator assembly connecting the input and output members. The controller determines, via a method, an input and output speed of the variator assembly, converts the output speed to an equivalent input speed using a calibrated variator speed ratio, and calculates a gross slip of the variator assembly using the input and equivalent input speeds. A gross slip flag is set only when the gross slip exceeds a calibrated slip value for a predetermined duration. A CVT assembly includes the controller, input and output members, and variator assembly. The variator assembly may include drive and driven pulleys, a drive mechanism connecting the pulleys, and an actuator applying a clamping force to one of the pulleys.

Abstract: A method of controlling a variator that requires clamping pressure between a first component and a second component to transfer torque therebetween, such as a continuously variable transmission, includes calculating a theoretical clamping pressure, and multiplying the theoretical clamping pressure by a multiplier to define a commanded clamping pressure. The multiplier includes a value that is variable between a minimum multiplier value and a maximum multiplier value. The value of the multiplier is based on current operating conditions of the variator. The commanded clamping pressure is applied to the first component and the second component to generate friction and transfer torque between the first component and the second component.

Abstract: A vehicle includes an engine and transmission having gear sets, an input member that is continuously connected to the engine and a gear set, a binary clutch assembly, a speed sensor, and a controller. The binary clutch assembly includes a freewheeling element holding torque in one rotational direction, and also a selectable one-way clutch (SOWC) portion holding torque in two rotational directions when applied. The controller executes a method to transmit a first binary clutch command to the binary clutch assembly and thus apply the SOWC portion at vehicle launch, and calculates, via the processor, an acceleration value of the vehicle using the measured speed. The controller also selects a shift apply point of the binary clutch assembly as a function of the calculated acceleration value, and transmits a second binary clutch command to the binary clutch assembly to release the SOWC portion at the selected shift apply point.
