Kawasaki, Japan - Mitsubishi Fuso Truck and Bus Corporation (MFTBC) has announced full model changes for the first time in 21 years and new technologies that will feature next-generation, heavy-duty trucks scheduled for launching this year.

Through the use of these technologies, MFTBC’s new models will embody state-of-the-art “safety,” excellent “economy,” as well as “comfortableness and maneuverability” that support the driver.

New Technologies for Next-generation Heavy-duty Trucks

1. Development of Two Types of New Engines for the Japanese Market Conforming to 2016 Emission Control

① Newly developed 7.7 L 6S10 type engine

The engine is equipped with a two-stage turbocharger to achieve high torque and high output for a small displacement in an ultralight body, which is sufficient for heavy-duty vehicles. In combination with the new BlueTec® system, it realizes both low fuel consumption and low emission.

 Advanced combustion system for optimized fuel combustion

  • Improved combustion chamber
  • Two-stage turbocharger
  • High-pressure common rail system
  •  Newly adopted system to achieve low fuel consumption and low emissions, enabling low emission pressure loss, and after-processing with a high NOx purification rate and precise AdBlue® fuel injection control

  • New BlueTec® system (DPF [diesel particle filter] regeneration control + Urea SCR [Selective Catalytic Reduction])
  • New AdBlue® fuel injection system
  • Variable bulb-timing (at DPF regeneration)
  •  Idling stop and start system

    2. 12-Stage Mechanical Auto Transmission “ShiftPilot” Newly Developed

    The burden to the driver is mitigated by providing increased driver safety through easy driving by two pedals and smooth automatic transmission

     Enhanced shift feeling through shock mitigation

    Optimal tuning is provided for the new “Super Grate” to achieve a smoother transmission (shift feeling) compared with conventional models.

     Creep function is added

    By precisely controlling the half-clutch operation, a creep function similar to that available to a torque converter AT can be achieved. Operation at a slow speed will become easy, such as when driving in congested traffic congestion or using a vehicle with a platform.

     Hill holder function added to EZGO

    In addition to the EZGO (Easy Go: an auxiliary function for starting on an uphill gradient), a hill holder function has been added that makes it possible to maintain the force of the break for several seconds after releasing the pedal. This function is useful in starting on an uphill gradient that requires using the creep function.

     Locking free mode is added

    This mode increases the ability to move out from a muddy spot by turning off the creep function and expedites the disconnection action of the clutch.

    3. AMB plus

    Mitsubishi FUSO’s Active Mitigation Brake (AMB) has cleared the phase-2 regulation for collision avoidance systems which will be enforced in 2019 as an obligatory requirement. Collision damage is mitigated by an alarm and automatic braking when a hazard is sensed in case a vehicle ahead is running or stopping.

    4. ABA4

    Further refining AMB plus, ABA4 (Active Brake Assist 4) helps avoid a collision with a vehicle ahead that is stopping (avoidance is sometimes not possible and depends on conditions). Additionally, the risk of a collision with a pedestrian (or pedestrians) will be mitigated (avoidance is sometimes not possible and depends on conditions). This function conforms to the phase-2 regulation for collision avoidance systems which will be enforced in 2019 as an obligatory requirement.

    5. Active Attention Assist

    Active Attention Assist further reinforces the technology of the driving attention monitor in the conventional MDAS-III by additionally equipping it with an infrared camera system. A driver monitor camera captures the driver’s face movement and motion, to monitor driver attention. Sensing a driver’s eyes are off the road while driving and the motions of the eyelids, a lowering of driver attention is alerted to by a buzzer and display on the screen.

    6. Active Sideguard Assist (First in Japan)

    This is a safety device that warns of a hazard hidden in the left blind spot. This spot, that will become a blind spot for a driver, is monitored by a radar and the driver is warned, while an alarm is sounded and a lamp gives warning when the left direction indicator is activated or during steering.

    7. Proximity Control Assist

    Automatic stop and automatic start functions have been added to auto cruising that help to maintain a distance between vehicles going in the same direction. The new function will be especially useful in traffic congestion on an expressway. Its automatic stop and start function will mitigate driver fatigue and will keep rear-end collisions to a minimum.

    8. 3-D Predictive Control of Power Train

    This system is designed to achieve low fuel consumption cruising by forecasting road inclination through GPS and 3-D map information during auto cruising. Optimal fuel injection control and gear step selection, and positive eco-roll control will avoid unnecessary fuel consumption, in order to improve fuel efficiency. This function will be useful especially on expressways with many uphill and downhill slopes.
