Scania upgrades Opticruise transmission control with new Performance Modes
As a result of the continual evolution of the product range, Scania has introduced an upgraded version of the highly popular Opticruise gearchange and transmission control system.
The most significant change of the Scania Opticruise is the adoption of Performance modes.
There are four Performance Modes: Standard, Economy, Power and Off-road.
Each version of the new Scania Opticruise is supplied with three modes as standard, which may be configured by the customer, and adapted by the supplying Scania branch in Australia.
The modes ensure that the vehicle can perform perfectly in a variety of driving conditions.
All on-highway trucks for Australia will be specified with Standard, Economy and Power modes.
Trucks that may be used in off-road situations such as the Ready Built Hooklift, Tipper, Mining and AWD versions will be specified with Standard, Power and Off-road.
A vehicle specified with Standard mode together with two other modes, gives the driver the option to fall back on the Standard mode in situations where the other installed modes are too restrictive or unsuitable for some reason.
Numerous new features have been integrated with Scania Opticruise to provide a predictive power train control system that delivers fuel savings of around 3% when coupled to the Streamline aerodynamic improvements.
Australian customers will benefit with a new version of Scania Ecocruise.
Scania Ecocruise adapts the cruising speed to the topography by sensing the load on the engine. Scania Ecocruise is only active in Economy mode and replaces Scania Active Prediction in countries where topographical data is lacking.
The new Performance Modes enable customers to tailor the vehicle’s performance to suit each type of operation, as well as to individual preferences regarding functionality and driver influence.
All settings can be altered or fine-tuned by a Scania workshop, which may involve locking out certain modes at the operator’s discretion. A user may allow access only to Economy mode, for instance.
Customised performance – up to three modes on each truck
The standard Performance Modes to be offered for on-highway vehicles will be Standard, Economy and Power in vehicles specified with Scania Opticruise.
• Standard mode is an all-round mode optimised to provide good fuel economy, while still delivering good hill performance. The system strives to run the engine at maximum torque during hill climbing.
• Economy mode is tuned to consume as little fuel as possible with some sacrifice in terms of trip time. Engine response is soft and kick down is disabled.
Alternative speed limiter settings of either, -4km/h (96km/h) or -9 km/h (91km/h) can be programmed, which engage automatically when switching to Economy mode.
Scania Ecocruise is only active in Economy mode, the fuel saving is up to 3% in hilly terrain. Scania Ecocruise adapts the cruising speed to the topography by sensing the load on the engine.
The speed window spans from 12% below, up to the set cruising speed (–12%, 0%). The minimum adjustable offset for downhill speed control with a retarder is 5 km/h above cruising speed in Economy mode (3 km/h in other modes).
• Power mode is intended for runs where transport time is at a premium. Engine response is more immediate and running the engine at maximum power, with slightly quicker gear changes than in Standard mode, optimises uphill performance.
• Off-road mode is suitable for driving in rough terrain and on surfaces with high rolling resistance. Vehicles specified for off-road driving have Off-road mode and it can be specified for other applications as well, for example hooklifts and tip trucks.
The system strives to keep the clutch engaged as much as possible to avoid interruptions in power delivery and traction. The number of gearchanges is minimised by allowing the engine to work over a wider rev band. Gear changes are faster with a priority on gear changing speed over comfort.
Basic version of Scania Opticruise with limited functionality.
Scania has also developed a simplified gear changing system that limits the possibilities for the driver to influence gear changing. Large fleet owners, whose drivers frequently drive different brands, typically request this shortcut to even better fuel economy.
Scania Opticruise Basic for long-haulage:
• Fully automated Scania Opticruise (with automatic clutch).
• Standard and Economy mode.
• Scania Ecocruise.
• Speed limiter set at 96 km/h or 91 km/h.
• Kick-down disabled.
• Manual gear changing disabled (above 50 km/h).
Scania Opticruise functionality.
When introduced in 1995, Scania Opticruise was one of the first automated gear changing systems in the market and it took driver comfort and driver support to new levels. The functionality has been continually refined ever since, turning Scania Opticruise into a comprehensive power train management system.
Scania in Australia offers the fully automated version (2-pedal) of Opticruise as standard, although the 3-pedal version may be available to special order depending on application. Scania is the only manufacturer offering automated gear changing with an optional clutch pedal.
On the Fully Automated system, the automatic clutch is electro-hydraulically operated, providing exceptional precision and smoothness.
All gearchanging controls are integrated in the right hand wand on the steering column, which also controls the Scania Retarder (if fitted).
