TCS function, high speed

TCS function, high speed


At 22 km/h (13.5 mph), the TCS function changes its mode of operation and starts modulation by limiting engine torque on the wheel that first starts to spin, i.e. the wheel with the lowest friction.

The limit for modulation by brake application lies somewhat higher, which is to say that braking is used on the spinning wheel when engine torque limitation is inadequate.

Brake application is used at speeds up to 100 km/h.

Primary limitation of engine torque means that no extra tractive force is transferred to the outer wheel when cornering. The outer wheel then has a sufficient margin of grip to take up steering forces to the full. The driver avoids being taken by surprise as the front wheels suddenly lose traction.

At 22 km/h (13.5 mph), wheelspin is allowed to reach 2 km/h (1.2 mph) or about 9%. After that, the curve rises in a straight line to 150 km/h where a wheelspin of 5.2 km/h (3.2 mph) or about 3.5% is allowed. At 150 km/h, the curve breaks again and permissible wheelspin will follow the increase in speed proportionally at about 3.5%.
