AI Technical Summary
Existing emergency stop assistants in motor vehicles face a high risk of unintentional deactivation due to varying driver states, particularly in situations where the driver's condition deviates from a normal, controlled state, leading to potential safety hazards.
An electronic computing device in the vehicle determines the driver's state during emergency stop assistant activation, comparing it to a predefined normal state and applying specific termination criteria tailored to different driver states, ensuring the assistant is deactivated only when intentional criteria are met, thereby reducing the risk of unintentional deactivation.
The solution provides robust and reliable operation of the emergency stop assistant by adapting termination criteria to various driver states, preventing accidental deactivation and ensuring safe vehicle control, especially in cases of medical emergencies or erratic driving conditions.

Abstract
Claims
[1] Method for operating a motor vehicle, in which by means of an electronic computing device - a state of a driver of the motor vehicle is determined while an emergency stop assistant is activated, which is designed to stop the moving motor vehicle at least partially automatically (V1), - the determined state is compared with a given normal state (V2), - in the event of a detected deviation of the detected state from the predetermined normal state, at least one termination criterion associated with the detected state is determined which deviates from a normal termination criterion associated with the normal state (V3), and - it is checked whether the termination criterion specified for the determined driver condition is met (V4), whereby the emergency stop assistant is deactivated if the specified termination criterion is met (V5). [2] Method according to claim 1, characterized bythat at least one measured value of the driver of the motor vehicle is determined by means of a detection device and, depending on the at least one measured value, the state of the driver is determined from several predetermined states. [3] Method according to claim 2, characterized by that the first predefined state is a calm state and the second predefined state is a hectic state. [4] Method according to claim 3, characterized by that at least one first specific termination criterion is specified for the first state and at least one second specific termination criterion is specified for the second state, wherein the at least one first termination criterion and the at least one second termination criterion are different from one another. [5] Method according to claim 4, characterized bythat as the at least one first specific termination criterion a driver activity is specified which is faster and / or stronger than a respective first predetermined limit value, and / or as the at least one second specific termination criterion a driver activity is specified which is slower and / or weaker than a respective second predetermined limit value. [6] Method according to one of claims 2 or 3 to 5 with reference to claim 2, characterized by that the at least one measured value is determined by means of a driver observation camera as a detection device. [7] Method according to one of claims 2 or 3 to 6 with reference to claim 2, characterized bythat the at least one measured value is determined by means of a capacitive measuring device of a steering wheel and / or by means of a vibration sensor of the steering wheel and / or by means of an accelerator pedal sensor and / or by means of a brake pedal sensor and / or by means of a belt sensor and / or by means of a steering torque sensor as a detection device. [8] Method according to one of the preceding claims, characterized by that the emergency stop assistant is activated if it is determined that at least one specified action by the driver is omitted for a defined period of time. [9] Method according to one of the preceding claims, characterized by that the emergency stop assistant is activated when a medical emergency of the driver is detected. [10] Motor vehicle which is adapted to be operated in a method according to one of the preceding claims.
