Intelligent Trailer Program Driver Comfort and Effectiveness

Suite of tools designed to make trailer operations easier and more effective for the driver.


What will the Intelligent Trailer Program Driver Comfort and Effectiveness Functions provide?

Retaining skilled drivers is the key to run an efficient operation. These Intelligent Trailer Program functions provide a toolbox to contribute to effectiveness, safety and comfort.



Control pad to monitor and operate the trailer

The simple multilingual control pad allows the driver to access key trailer information and to operate available trailer braking and suspension functions even when uncoupled A ruggedized device mounted on the side of the trailer and linked directly to the Trailer EBS or Trailer ABS Enables access to data on axle load, mileage status, tire pressure and temperature, brake pad wear and Trailer EBS failure codes Receives Trailer EBS error codes when the truck is not connected to the trailer helping to optimize maintenance schedules Activates Trailer braking and suspension functions, such as WABCO’s OptiLevel™, OptiTurn™ and Immobilizer if available on the trailer 

NewSmartBoard generation comes with 8 buttons instead of 3, larger display and selfprogramming menu structure for faster and more convenient operation Wider range of operating temperature (from -30° to +65°C) 18 pre-programmed languages Flexible mounting position Two versions: for ADR applications, a non-battery variant is available 


Traction Help

Enhances grip on slippery roads

Enables easier starting on hills or on slippery roads covered in sand, mud, snow or ice

Trailer EBS lifts the first trailer axle, adding weight to the truck's rear axle resulting in a stronger grip on the road 

Automatically lowers the trailer axle once the vehicle is driving above the parameterized speed-threshold

Can be activated from within the cabin using the WABCO OptiLink™, via a switch or by brake pedal

Can be set as an automatic function during the winter season (only in combination with WABCO's SmartBoard, telematics or the truck’s time stamp)

Reduces tire wear by avoiding wheelspin

Helps to minimize accidents caused by swerving trailer tail

Automatically respects total permitted load of the axles


Automatically returns the trailer to normal driving height when driving

Automatically protects the trailer by restoring the driving height after loading/unloading when a pre-programmed speed is reached.

Improves efficiency and speed of delivery times by allowing the driver to start driving after loading or unloading without having to leave the truck cabin

Helps to avoid damage to the chassis, axles and fragile cargo

Speed level programmed between 5-20km/h

Return-to-Ride is one of the six OptiLevel™ functions and works as stand-alone function

Direct valve control with TASC (Trailer Automated Suspension Control) enabling rapid level change

Finisher Brake

Synchronizes the tipper and an asphalt finisher machine while unloading

Automatically synchronizes tipper and asphalt finisher vehicle by maintaining a constant braking pressure – ensuring asphalt is laid evenly

Prevents costly damage and spillage when unloading tippers during downhill operations

Activated by a switch when the tipper starts lifting to unload asphalt into the finisher machine 

Uses WABCO’s SmartBoard or OptiLink™ to adjust braking pressure during uphill and downhill to compensate for increasing road slope angles

Trailer EBS softly brakes (0.5 bar to 1 bar) to stay synchronized with the asphalt finisher machine


Trailer Length

Measures and displays the actual length of telescopic trailers

Trailer EBS converts the positions of proximity switches installed on the extendable platform into a trailer length

The actual trailer length is displayed in the SmartBoard

No need for manual measuring or guessing

Can be retrofitted up from Trailer EBS E Premium version 4 (2014)


Steering Axle Lock

Enables straight driving whilst in reverse

Trailer EBS Automatically locks self-steering axle during reversing operations to enable straight driving and to maintain trailer stability

Automatic locking of the steering axle on high speed helps to increase vehicle stability and safety

Automatic locking and unlocking saves time and increases driver safety and comfort

Reduces tire wear during reversing

Function activated via both, vehicle speed and reverse signal
