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.
