Ready-to-use solutions: 

With the CT-SUITE tool, Poclain Hydraulics is making electronically controlled hydrostatic transmissions more accessible by allowing customers to create their own software management. Based on a library of fully tested software functions, each customer can combine all the necessary functions to generate their software in just a few clicks, reducing development time and costs without any further help.

Travel/Work modes for machines that have to travel fast from one working area to another:
Use the same hydraulic installation to be able to travel fast between sites while maintaining a high torque transmission at on-site
Best efficiency in both modes (work and travel)
Energy saving
Noise reduction
Driver comfort
Work precision
Anti-Stall to prevent engine stalling when torque requested to engine can exceed the engine capacity:
Driver stays focused on the work at hand, not on engine management
No need for oversized engine
Increased driving comfort
Automotive Control to drive the machine like a car:  
Automatically adapts the machine’s speed to engine rotation speed.
Compatible with engines with cable control.
Increased fuel savings compared to constant engine speed
Easy to drive and simple to integrate 
Smart Automotive for efficient control of the pump and the engine together:
Independent engine and pump curves
Reduces noise emissions 
Increased fuel savings compared to constant engine speed
EcoDrive™ compatible
Multi-mode compatible
Cruise Control / speed control loop control with Smart Automotive, when precise machine speed is needed for working process:
Driver only focuses on work at hand, not on machine speed
Better job quality
Electronic Inching when precise machine approach is needed, or when engine power is needed with very low or null machine speed:
Precise machine approach 
Engine power needed for tools at very low or null machine speed – better tool management
Increased driving comfort
Automatic speed shifting, smooth speed change management when machine needs to switch automatically “on the fly” between high torque (first speed) and high speed (second speed, third speed etc.):
Easy to drive
Preserves motors – increased lifetime
Comfort
Hydrostatic braking with electronic pedal to adjust hydrostatic braking (mandatory with automotive control):
Easy to drive (car like)
Comfort
Safety
Combined braking with hydraulic brake pedal (VB) when hydrostatic braking is needed to reach a level of deceleration:
Better braking performances
Reduces friction brake wear – increased lifetime
Hill Start to stop and restart the machine on a slope:
Easy to drive
Safety
Preserves ground
EcoDriveTM for more environmental (eco) driving with fuel saving and lower engine noise.
Command Limiter for machines working at low speeds with high engine speed (e.g. approach mode):
Better machine manoeuvrability
Driver Presence increases the safety at the worksite, preventing machine from moving without a driver. 
Accelerator Joystick function that is mostly used in tractors’ control agronomy:
Smooth joystick control of requested speed
Control of acceleration and deceleration levels
System protection functions (over-power protection, over-pressure protection, over-temperature protection, over-speed protection) to preserve hydraulic components and increase the lifetime of the machine.
Safety start management for safer work. It ensures that all required safety conditions are met before allowing the machine to move.

Customizable and easy to use

SmartDrive™ is designed for easy programming, parameterization, personalization and diagnosis. It can be applied to many different applications through a programming tool CT-SUITE.

 

Beside standard functions, we also offer customized customer-specific application software based on the SmartDrive™ modular system that is in-series production-ready as pre-installed software for SmartDrive CT electronic control units. Some application specific systems are available with pre-defined software, e.g. Skid-Steer System.

 

As hardware we use SmartDrive CT electronic control units.
