GPS-assisted cruise control: MAN EfficientCruise ^{[Van-LimitsSystem]} with PredictiveDrive

The MAN EfficientCruise ^{[Van-LimitsSystem]} GPS-assisted cruise control system detects uphill and downhill gradients along the route up to three kilometres (two miles) in advance. As a result, the cruise control can always adjust the selected gear and speed to achieve optimum economy whilst driving. Downshifts are suppressed where appropriate. This ensures fewer traction interruptions and fuel savings.

MAN EfficientCruise ^{[Van-LimitsSystem]} takes into account the route ahead and calculates the most efficient driving style. A smooth and consumption-oriented intervention in the gear selection not only eliminates traction interruptions, but also offers a harmonious driving experience. The driver simply selects the desired speed and one of the four possible speed tolerance levels (ECO Level I – IIII). The ECO Level can be adjusted at any time while driving.

• ECO Level I: Lowest deviation from the set speed – suitable for heavy traffic and poor weather conditions
• ECO-Level IIII: Maximum deviation from the set speed – suitable for low traffic volumes on motorways and country roads

The new PredictiveDrive system complements the effect of MAN EfficientCruise, ^{[Van-LimitsSystem]} especially when approaching uphill and downhill gradients. Depending on the situation, it weighs up possible speed and gearshift strategies and ultimately selects the most fuel-efficient one. The aim is usually to gain as much momentum as possible on the uphill gradient, e.g. by accelerating briefly beforehand and shifting down early to ensure an adequate excess of power.

MAN EfficientCruise ^{[Van-LimitsSystem]} and PredictiveDrive are already active from around 30 km/h. The system operates both for free driving and in cruise control mode. The anticipatory system responses on uphill gradients ensure significantly improved drivability and thus also increase driver acceptance of dynamic torque adjustment.

In combination with MAN EfficientRoll, the MAN EfficientCruise GPS-assisted cruise control ^{[Van-LimitsSystem]} helps you to save even more fuel and your vehicle is even more environmentally friendly on the road.

Thanks to MAN EfficientRoll with GPS preview, coasting is intelligently controlled: If fuel can be saved, the gearbox automatically shifts to the neutral position “N” – even on a slight downhill slope. Thus the momentum is maintained and the vehicle loses speed less quickly than with an engaged gear. When coasting, the engine only runs at 550 rpm (instead of the normal idling speed of 600 rpm). This helps to further reduce fuel consumption.
