Patent CA-2392791-A1 (CA)
Title: Control system for reverser transmission having aggressive and non-aggressive modes
Inventor: BURGART JOSEPH G
IPC: F16H61/02
Filed: 2002-07-09
Abstract: A control system for a utility vehicle transmission provides for operator selection of vehicle "aggressiveness," or rates of acceleration in response to operator command. The aggressiveness of a vehicle's performance can be controlled by modulating control signals to proportional control valves, which determine the transmission acceleration, according to two or more electrical ramp-up (or ramp-down) profiles, in response to an operator's acceleration command (or deceleration command). The transmission control system includes a controller, directional switches and electro-hydraulic valves which control hydraulic pressure in the clutch packs in a reverser transmission. The operator is provided with a two-position set switch. With the set switch in the less aggressive position, in response to an operator's command, the software in the controller provides a relatively slow current ramp to energize the control valves. With the switch in the more aggressive position, the current ramps and resultant pressure ramps are faster, thus causing more aggressive transmission operation for the reverser transmission.
