Abstract

In a control process for increasing the traction in the case of a vehicle while the vehicle stability remains almost the same, a wheel slip is determined at the powered wheels and is compared with at least one slip threshold value. The driving power is reduced when the wheel slip exceeds the slip threshold value. For improving the traction on a loose base, at least one slip integral is formed between the powered and the non-powered wheels. The at least one slip threshold value is continuously determined as a function of the at least one slip integral.
