Electronic Transmission Automotive Control (ETAC)systems provide many cost and operating benefits.Applications can include lift trucks, telehandlers,railway maintenance equipment, utility vehicles, andcompact wheel loaders. Within the ETAC system, theelectronic controller is integrated with the enginethrottle management system, as well as a closedcircuit pump. It drives high performance proportionalvalves and uses electronic swashplate feedback toprovide precise, dynamic system control.Automotive control of a hydrostatic drive allowslarge vehicles to be operated in a way similar to astandard automobile with an automatic transmission.A single throttle pedal controls the engine andtransmission, giving output speed and torque asneeded for vehicle operating systems.

EATON ETAC Control: Electronic Transmission Automotive Control User’s Manual E-HYOV-TM002-E September 2007 3

• Adjustable performance –Within the capabilities of theengine, vehicle responsiveness(aggressive vs. smooth) can beadjusted relative to changes inengine speed. The settingsaffect both acceleration anddeceleration modes ofoperation.

• Anti-stall – ETAC’s scalable anti-stallsensitivity enables maximumengine loading and allows useof maximum available enginepower over the full speedrange. The response rate andload profile is adjustable tospecific engine characteristics.

• Operator Interfaces –Specifications andrecommendations are providedfor all system components,including the foot pedal,forward/neutral/ reverseselector switch, inching pedal,and interlock switches (parkingbrake and operator presence).

• Safety –The safety features ensurepump displacement ismaintained at mechanicalneutral by interrupting powerto the pump control. Othersafety interrupts includeparking brake release andoperator presence switches.

• Hydrostatic braking –ETAC uses full capacity of thehydrostatic system for slowingvehicles, which reduces thedemands on service brakesystems. Hydrostatic-brakinggreatly reduces the need forfrequent brake servicing andassociated vehicle downtime.It is initiated by simplyreleasing the throttle pedal.More aggressive brakingaction can also be obtained bydepressing the inching pedal.

• Inching control –With this option, a secondfoot pedal allows the user todestroke the pump, allowingthe engine to maintain speedin a loaded condition. Inchingcontrol is useful when precisepositional control is requiredor when engine speed mustbe increased independent oftravel speed to support othermachine work functions suchas raising a load on a forklift.

• Electronic Control Module –The brain of the system is theMAESTRO Electronic ControlModule. This unit can beconfigured, by means ofsoftware, to perform a widerange of functions.

• Performance – The ETAC system offers moreconsistent performancecompared to hydromechanical(automotive drive) systems.Performance is not impactedby temperature effects on oil viscosity because enginespeed is measuredelectronically. The use of electronic control offers the capability to moreprecisely match transmissionperformance relative to enginepower. The ETAC’s controldelivers greater maximumvehicle performance, reducedfuel consumption and fastercycle times resulting inreduced overall vehicleoperating cost.

• Hot shifting –This feature allows thetransmission to be rapidlyshifted from forward toneutral to reverse (or viceversa) without damage to thevehicle powertrain system.Hot shifting improvesproductivity compared tomechanical systems bysimplifying operation andreducing operator fatigue.

• Temperature stability – The system’s electronicswashplate position (ESP)technology makes systemcontrol insensitive totemperature and/or oilviscosity. This ensures positiveneutral – even under extremecold start conditions – withoutthe complexities of extravalves. The control in turn,provides smooth, precise,reliable, and repeatableoperation with predictableperformance.

• Setup –The operator must size theHST transmission, includingpumps and motors, whensetting up the system designsoftware. From thosecalculations, many details canbe tailored for the neededsystem applications, including:

- vehicle parameter settings

- vehicle speed vs. travel pedal profile

- engine speed vs. travel pedal profile

- pump displacement vs.engine speed, and

- engine torque curve.

Wiring Guidelines

• It is recommended to use 18AWG wire per SAE J1128

• Appropriate wiring practices should be usedfor installation to avoid abrasion, strain, damage,and EMI (electromagneticinterference). Do not routeETAC harness wires in thesame bundle as otherpower wires (example,powering motors andactuators).

• External circuits must not be connected to thesensor or solenoid wires.

• All sensor supply andground wires must bespliced together within 8 inch wire length of theMAESTRO controller. Allground wires should beconnected to a centerpoint.

• All switch supply wiresshould be spliced togetherwithin 8 inch wire lengthof the MAESTRO con-troller.

• Provide switched 12 or 24volts with a 6-amp fastblow fuse. Provide anemergency stop switch.

• As practical, route thewires in bundles andenclose the bundles insleeve material such asconvoluted tubing, meshor heat shrink tubing. Besure to choose temperatureappropriate material. This will help prevent wirefailure due to abrasion,accidental nicking or cutting.

• Avoid routing wires aroundsharp corners or roughedges. Use grommets asappropriate. Avoid makingsharp turns with the harness, for this mayincrease stresses.

• Secure the wire bundlesin channels or use wireties to secure harness to frame. Securing theharness will help preventwire fatigue and accidentaldamage from movingparts or maintenancework. Avoid long stretchesof unsupported harness.

Allow the harness tomove as the frame willmove in the application.

• Avoid high temperaturesources such as exhaustsystems and engineblocks.

• Avoid routing wires onsources of high vibration.

• When possible locate connectors shielding themfrom direct spray. Usemanufacture connectorboots, if available, to helpprevent high-pressurespray directly on a connector where thewires enter. Do not locate connectors, or wire slices,in troughs that can retainwater and leave the connector submerged inwater or other chemicals.

• Use wire routing to prevent similar connectorsfrom being mistakenlyconnected by adjustingwire length so only thecorrect connector can beengaged.

Questionnaire:Application Data Sheet

ETAC is an electronic hydrostatic drive control which enables a vehicle to be driven in a manner similar to an automobilewith automatic transmission. Pump displacement is related to engine RPM.

ETAC is a propulsion system with anti-stall for off-road vehicles such as fork lift trucks and utility vehicles that are not equipped with boom and bucket work circuits. Inching capability is an available option which may not be needed if propulsion is the only hydraulically powered function.
