Operation Characteristic

VEHICLE STARTS CONTROL

• At the start, torque distribution for front and rear wheels is fixed by electric control and stable start is achieved.
• Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.

NORMAL CONTROL

• On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close to rear-wheel drive and it results in better fuel efficiency and provides FR-like steering characteristics.
• When spin occurs on rear wheel, distribute optimum torque to front wheel and keep stable driving.
• The vehicle cornering status is judged according to information from each sensor, and the optimum torque is distributed to front wheels for preventing tight cornering/braking symptom.
