Claim Text:
1. A method for activating or deactivating an automatic driving function of a technical vehicle piloting system that assists a driver of a motor vehicle, the pilot system having states between which predefined transitions are possible based on predefined conditions, including at least three system states of pilot not ready, pilot ready but inactive, and pilot active, the method comprising: in response to a request of the driver, transitioning from the ready but inactive pilot state to the pilot active state; in response to a request of the driver, transitioning from the pilot active state to the ready but inactive pilot state; in response to a driver braking measure, a steering measure and/or a kick-down measure by the driver, transitioning from the pilot active state to the pilot not ready state; in response to a driver braking measure, steering and/or acceleration measure and/or exceeding predefined limit values with respect to vehicle behavior and/or driving behavior, transitioning from the ready but inactive pilot state to the pilot not ready state; and in response to predefined pre-requisites for system readiness having been met, transitioning from the pilot not ready state to the ready but inactive pilot state, wherein the vehicle pilot system further comprises the further system state of escalating driver warning in which the driver is requested to readopt his driver behavior caused by the automatic driving function or to assume vehicle guidance, and wherein the vehicle pilot system further comprises the further system state of minimal risk maneuver, which is used to change the vehicle to a minimal risk state using a suitable driving maneuver.
