CR-CR Four-Speed Transmission

This example shows a four-speed transmission with two planetary gears and five clutches. The test sequence steps through the four forward gear ratios, switches to neutral, and then applies a brake clutch to the output shaft of the transmission.

To manually select the gear for the transmission, configure the Clutch Control subsystem to use the Manual variant using the hyperlinks. The Manual control subsystem has blocks from the Dashboard library that let you select the gear and apply the brake by clicking on them with the mouse.

The plot below shows the input and output shaft speeds of the transmission. The clutch states are also plotted (locked or open), indicating the selected gear of the transmission.
