1. A method for deactivating an automated driving mode of a vehicle, the method comprising:
determining a manual steering torque acting on a steering wheel of the vehicle;
determining a system steering torque, wherein the system steering torque is generated by a control system during the automated driving mode of the vehicle;
detecting whether at least one of a vehicle user's hands is on the steering wheel;
determining whether the vehicle user's gaze or head orientation is not directed towards the front of the vehicle or determining whether there is a lateral collision risk for the vehicle and a direction of the collision risk;
automatically terminating the automated driving mode when the at least one of the vehicle user's hands is detected on the steering wheel and the manual steering torque exceeds the system steering torque by an amount of a first predetermined value;
automatically terminating the automated driving mode when neither of the vehicle user's hands are detected on the steering wheel and the manual steering torque exceeds the system steering torque by an amount of a second predetermined value;
automatically terminating the automated driving mode when the manual steering torque exceeds the system steering torque by an amount of a third predetermined value and it is determined that the vehicle user's gaze or head orientation is not directed towards the front of the vehicle; and
automatically terminating the automated driving mode when the manual steering torque exceeds the system steering torque by the amount of the third predetermined value and it is determined that there is the lateral collision risk for the vehicle and the manual steering torque is acting in the direction of the collision risk,
wherein the second predetermined value is greater than the first predetermined value and the third predetermined value is greater than the second predetermined value.
