Gearshift functions for increased comfort, efficiency and safety
The shifting strategies of the MAN TipMatic® semi-automatic manual gearbox are designed to provide an optimum balance between comfort, efficiency and speed. The engine, clutch and gearbox are adjusted to each other in such a way that every shifting operation is completed as quickly as possible. SmartShifting is an evolution of the SpeedShifting function. While SpeedShifting allows for quicker shifting between the three highest gears (10th, 11th, and 12th), SmartShifting allows for a combination of fast shifting processes in all gears. This means, for example, a quicker downshift of the transmission on inclines, thus maintaining the momentum and saving the truck fuel.
Using the electronically controlled engine brake in the so-called upshift assistance (HSU) makes it possible to control fast jumps of up to three gears, especially on inclines. The intelligent software calculates the optimum gearshift speed using data such as the accelerator position, the vehicle mass and the calculated driving resistance. The optimum speed in this case is not necessarily the fastest. It is rather an ideal compromise between gearshift speed, comfort and material wear.
Comfortable idle speed driving
Idle Speed Driving allows for comfortable driving at idling speed. It enables the driver to manoeuvre the truck with exceptional precision or to just let the vehicle cruise along comfortably in slow-moving traffic on the motorway. After moving off, the vehicle travels at a low idling speed of around 600 rpm, without the driver having to press the accelerator. If the engine torque is insufficient at idling speed, the MAN TipMatic® shifts down. The clutch opens as soon as the driver presses down on the brake pedal.
Dynamic start-up - even with maximum load and on rough terrain.
Optimum gear selection is provided by the MAN TipMatic® load detection function. It automatically selects the optimum gear for moving off when the vehicle is empty or fully loaded. In addition, the high transmission ratio spread and the gradient recognition software function also support excellent moving-off behaviour.
The rocking-free function of the MAN TipMatic® facilitates moving off if the truck is stuck in snow or damp, muddy ground. It automatically selects the best gear to reduce the torque to the drive wheels, thereby avoiding wheel spins. This makes it easier for the driver to ‘rock’ the truck free.
