METHOD AND APPARATUS FOR CHANGING AN AUTONOMOUSLY TRAVELLING MOTOR VEHICLE TO A SAFE STATE
First Claim
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.

Abstract
A method and an apparatus for changing a motor vehicle in an autonomous travel mode to a safe state when the driver of the motor vehicle is not able to monitor the autonomous travel mode and to assume control of the motor vehicle. The vehicle driver is warned using warning signals of increasing intensity; other road users in the area surrounding the motor vehicle are warned using optical and/or acoustic signals; the motor vehicle is braked and/or accelerated repeatedly such that parts of the body of the vehicle driver noticeably move in the direction of travel owing to inertia (the braking and/or acceleration being so brief that the travel speed of the motor vehicle changes relatively little); and the motor vehicle is brought to a standstill or is kept at a standstill by automatic braking in order to change the vehicle to a safe state.

11. A method for placing a motor vehicle operating in an autonomous driving mode into a safe state comprising:
-
detecting that a vehicle driver has failed to activate a device acting as a dead man'"'"'s switch; generating warning signals to alert the driver, the signals increasing in intensity over time; activating a visual signal to warn other road users in a vicinity of the motor vehicle; and braking and/or accelerating the motor vehicle repeatedly with an intensity selected to cause the driver to perceive inertial movement. - View Dependent Claims (12, 13, 14)
