1. A method, for notifying a driver of a vehicle to inform the driver of activation of a request for the driver to take control of the vehicle, the vehicle having an adaptive cruise control, comprising the steps of:
- (a) signaling that at least one of a maximum braking force and pressure controllable by the adaptive cruise control is being applied and a deceleration therefrom is not sufficient to automatically decelerate the vehicle in time and to a sufficient degree; and
(b) activating the request for the driver to take control when at least three criteria, including at least two criteria relating to deceleration values and one additional criteria, are simultaneously satisfied.

Abstract
In a method and a device for triggering a request for taking control (RTC), a driver of a vehicle having adaptive cruise control is signaled that the adaptive cruise control system may not be capable of controlling a driving situation, and that the driver may have to intervene, the signaling of the driver being generated in accordance with at least two vehicle variables, whereby the probability of a false alarm by the system is reduced, and the triggering of the RTC is adapted to the instantaneous vehicle speed.

8. A method for notifying a driver of a vehicle to inform the driver of activation of a request for the driver to take control of the vehicle, the vehicle having an adaptive cruise control, comprising the steps of:
-
(a) signaling that at least one of a maximum braking force and pressure controllable by the adaptive cruise control is being applied and a deceleration therefrom is not sufficient to automatically decelerate the vehicle in time and to a sufficient degree;
(b) activating the request for the driver to take control when at least two criteria relating to deceleration values are simultaneously satisfied; and
(c) activating a request for the driver to take control when one of at least one further condition is satisfied independent of the activating step (b). - View Dependent Claims (9)

10. A device for notifying a driver of a vehicle to inform the driver of an activation of a request for the driver to take control of the vehicle, the vehicle including an adaptive cruise control, the request for the driver to take control signalling that one of a maximum braking force and a maximum braking pressure controllable by the adaptive cruise control is being applied and that a deceleration resulting therefrom is not sufficient to automatically decelerate the vehicle in time and to a sufficient degree, comprising:
an arrangement configured to activate the request for the driver to take control when at least three criteria including at least two criteria relating to decelaration values and one additional criteria are simultaneously satisfied.
