Automatic Traction Control

Automatic Traction Control

In normal mode, Volvo's articulated truck Automatic Traction Control (ATC) selects fuel-saving 6x4 drive and only engages 6x6 drive when the operating conditions call for it.  This translates into maximum productivity with minimal fuel consumption and long operating life.

Advantages of ATC:

  • Easier operation
  • Drivetrain protected against unnecessary damage/wear
  • Reduced fuel use and tire wear
  • Increased productivity
  • Reduced operating costs
  • Improved profitability

Components of ATC

The ATC-system consists of a number of sensors that control the differential locks with signals to the articulated truck’s electronics, ECU.  The sensors immediately sense the slightest wheel slip and the ATC-system instantly engages the needed drive combination.  This means the operator will always be running the machine with the right drive combination.

Valuable advantages

ATC is an investment that pays off fast. Always operating with the correct drive combination means that the job gets done quickly and effectively.  It reduces articulated truck fuel consumption by up to six percent – and the machine’s environmental impact is reduced by just as much.  It’s also easy to see the advantages with ATC in the long run.  ATC reduces tire wear and protects the articulated truck's drivetrain against damage and unnecessary wear.

Example cost savings (A40E)

  • 2000 machine hours per year
  • Fuel consumption 25L(6.6gal) per hour
  • $3 per gallon diesel fuel
  • $50,000 for a set of 29.5 tires
  • 6000 hours lifetime on a set of tires with ATC
  • 6% savings on fuel and 10% increase in tire life.

Extensive field testing of Volvo articulated trucks with ATC showed a maximum of 6% savings due to proper engagement and disengagement of 6x6 mode.

Fuel Savings:
2,000 x 6.6 x 3 x 6% = $2376 per year

Tire Savings:
50,000 x 10% / 6000 = $.83 per hour = $1667 per year
Total savings per year = $4043
