摘要：
In a method of determining the traction of motor vehicle wheels on wet pavements, a surge force generated by a water film on the pavement in front of at least one of the vehicle wheels is measured and from the measured surge force value and the instantaneous vehicle speed a critical speed at which the vehicle wheel will aqua-plane is determined and this critical speed is displayed to the driver or it is used to control a vehicle drive unit to keep the vehicle speed below the critical speed.
