Abstract

A method ascertains a drive clearance after a software update for a set of controllers of a vehicle. The method includes determining a first deviation between the first target state and the first actual state of the software updated. If the first deviation indicates, then a second deviation between the second target state of the set of second target states and the second actual state of the set of second actual states for a first controller is determined. The first controller is linked to a class from a specified controller classification, and one or more properties of controllers are linked to each class of the specified controller classes. If a second deviation indicates, and if a property of the ascertained class of the first controller indicates that the first controller can be downgraded, then the first controller is downgraded after the software update.
