Gearbox Interface Unit

All of the control methods associated with the transmission are run as part of the EMS2000 software. The EMS2000 receives inputs from the main sensors of this system, communicates with the gearbox interface unit (GIU) to control the transmission, accepts driver inputs and provides information to the driver via the instrument cluster.

The control of the transmission is integrated with the EMS2000 and a GIU enables this integration, acting as a slave/interpreter for the EMS2000.

All inputs and outputs of the ECVT control system pass through the EMS2000 and the GIU The EMS2000 monitors the speed of the transmission output shaft and communicates with the GIU to select the correct gear ratio to suit the current driving conditions. The GIU drives the park, reverse, neutral, drive and sport LED module to display the selected gear next to the gear selector lever and the EMS drives the instrument cluster display.
