摘要： 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.

摘要： A cruise control system for a utility vehicle (20), which is speed-controlled by a hydrostatic transmission (26), includes a controller (52( having an input for receiving a selectable set speed signal, and an output for sending a speed control signal to at least one proportional valve (106, 108) of a hydrostatic transmission servo control system. The vehicle ground speed is continuously monitored by a speed sensor (46) operatively associated with a rotating gear (40) in the vehicle drive train (26) that rotates in proportion to vehicle ground speed, to create a ground speed signal. The selectable set speed signal can be input to controller memory by driving the vehicle (20) at a desired ground speed and then activating a speed set switch (58). The speed control algorithm of the controller (52) thereafter compares the set speed to the ground speed signal from the speed sensor (46) and corrects the control signal to the proportional valve (106, 108) to correct hydrostatic transmission speed output.
