Abstract
A pneumatic control system (200) for controlling the automated shifting of the splitter section (114) of an automated compound transmission (110) is provided. Shifting of the splitter section is controlled by a differential area piston/cylinder actuator assembly (162) having a first chamber (168A) associated with low-speed operation and a second chamber (170A) associated with high-speed operation. Pressurization and exhaust of each of the chambers is controlled by an individual independently controlled solenoid actuated valve (202 and 204 respectively), each of which operates in response to control signals from an ECU 124.
