1. A method for placing a motor vehicle operating in an autonomous driving mode in a safe state if a driver of the motor vehicle is not capable of monitoring the autonomous driving mode,wherein if it is detected that the driver is not capable of monitoring the autonomous driving mode, the following steps are carried out automatically in sequence:

  • a) warning the vehicle driver using warning signals that increase in intensity with time;

    b) warning other road users in a vicinity of the motor vehicle using visual and/or acoustic signals;

    c) braking and/or accelerating the motor vehicle repeatedly with an intensity such that parts of a body of the vehicle driver move perceptively due to inertia, and furthermore so briefly that a current velocity of the motor vehicle changes relatively little; and

    d) bringing the motor vehicle to a stationary state by automatic braking and/or keeping the vehicle in the stationary state.
