What is the purpose of using the ASR system in a passenger car?
aPreventing skidding while engine braking.
bPreventing blocking of the braked wheels.
cPreventing skidding while moving off.
Why?
ASR limits wheelspin at the driven wheels when moving off and accelerating. It does this by reducing drive torque or braking a wheel that is losing traction. Answer A describes MSR, which counters wheel slip during engine braking, while answer B describes ABS, which prevents wheel lock during braking.
