The action of the ASR system is particu-

larly helpful under the following condi-

tions:

– Skidding of the inner wheel on a

bend, due to the effect of the dynamic

changes of the load or over-accelerating.

– Excessive power transmitted to the

wheels, also in relation to the conditions

of the road surface.

– Acceleration on slippery, snowy or icy

surfaces.

– In the case of loss of grip on a wet

surface (aquaplaning).

ASR FUNCTION (ANTISLIP

REGULATION): GENERAL

The ASR system integrates the VDC sys-

tem controlling the vehicle drive and com-

ing into operation automatically each

time one or both driving wheels skid.

Two different control systems are acti-

vated, depending on the skidding condi-

tions:

– If skidding concerns both driving

wheels, because it is caused by the exces-

sive power transmitted, the ASR system

cuts in reducing the power transmitted by

the engine.

– If skidding concerns only one driving

wheel, the ASR system cuts in automati-

cally braking the skidding wheel, with an

effect similar to that of a self-locking dif-

ferential.

For the VDC, ASR and

ABS systems to work

correctly, the tyres must be of the

same brand and type on all

wheels, in perfect conditions and

above all of the specified type,

brand and size.
