Volvo Trucks – Animation: How Automatic Traction Control works


Today most drivers activate
the front-wheel drive or diff lock before the terrain becomes difficult,
in order to avoid a standstill. With Automatic Traction Control, the driver can benefit
from better manoeuvrability right up until
the road conditions get worse. When the sensors
on one of the rear wheels detect that it’s starting
to lose traction, the all-wheel drive
is instantly engaged. A dog clutch then transfers the power
to the driven front axle and the truck can continue
without dropping either torque or speed. The driven front axle
then remains activated until the driver releases the throttle pedal.
