Abstract
A method for detecting slippery ground in a vehicle with automatic transmission includes detecting the instantaneous running conditions, with the aid of at least one parameter that represents the existence of slippery ground; on the basis of this detection, generating, by counting, a value that represents the change in running conditions as a function of time; comparing the value with reference conditions; as a function of the result of the said comparison, deciding whether or not the instantaneous running conditions correspond to slippery ground.
