Increasing the frictional force between a wheel of a road vehicle and a road

摘要

A system 12 for increasing a frictional force between a wheel 14 of a road vehicle 10 and a road 16 comprises at least one granulate container 20 with granulate 24 and an electronic the driving assist system 18. of the granulate container 20 scatters the granulate 24 in front of the wheel 14 in such a way that the friction force between the wheel 14 and the street 16 is increased. The the driving assist system 18 opens up the granulate container 20 automatically, if the the driving assist system 18 a reduced frictional force between the road 16 and the wheel 14 detects.
