Description

[0001] The invention relates to a method for controlling vehicle functions for a vehicle occupant after a vehicle accident. The invention further relates to a device for carrying out the method.

[0002] German patent application DE 10 2023 002 626 A1 discloses a method for operating a vehicle assistance system to support vehicle occupants after an accident. The vehicle has both environmental and interior sensors.The procedure involves analyzing traffic events in the immediate vicinity of the vehicle based on signals from the environmental sensors; determining the health status of the vehicle's occupants based on signals from the interior sensors; if the interior sensors determine that the occupants do not require assistance, the assistance system issues instructions for securing the vehicle based on the analyzed traffic situation; and if the interior sensors determine that the occupants are injured and require assistance, an image projection is activated, projecting text information onto the ground outside the vehicle, indicating that there are injured occupants in the vehicle who require assistance.

[0003] The invention is based on the objective of providing a method and a device for controlling vehicle functions of a vehicle for a vehicle occupant after an accident of the vehicle.

[0004] The problem is solved according to the invention by a method which has the features specified in claim 1 and by a device which has the features specified in claim 3.

[0005] Advantageous embodiments of the invention are the subject of the dependent claims.

[0006] According to the invention, a method for controlling vehicle functions for a vehicle occupant after an accident of the vehicle provides that - physiological and / or behavioral data of the vehicle occupant are determined based on recorded image data of the vehicle occupant and / or recorded vital data of the vehicle occupant after the accident, - the collected data are analyzed using at least one artificial intelligence-based model to identify stress and / or shock and / or overload indicators in relation to the vehicle occupant, - based on the identified stress and / or shock and / or overload indicators, a psychophysiological state profile of the vehicle occupant is derived and - Depending on the determined condition profile of the vehicle occupant, a lighting system to output at least one light pattern and / or an audio system to output acoustic signals and / or a display unit to display safety-relevant information and explanations provided to the vehicle occupant will be automatically activated as vehicle functions.

[0007] By applying this procedure, the risk of serious post-traumatic consequences for the vehicle occupant can be reduced, in particular by having a calming effect on the vehicle occupant by means of at least one emitted light pattern and / or the acoustic signals emitted by means of the audio system and / or the safety-relevant information and explanations provided.

[0008] In particular, the procedure serves as aftercare for the vehicle occupant following an accident, to calm and mentally stabilize them, using the light system and / or the audio system and / or the display unit to reduce the risk of serious post-traumatic consequences.

[0009] Measures initiated after an accident that correspond to the determined psychophysiological state profile can help the vehicle occupant to cope with the situation relatively well and to regain personal control that may have been lost due to the accident.

[0010] Exemplary embodiments of the invention are explained in more detail below with reference to a drawing.

[0011] This shows: Fig. 1 schematically a vehicle with a device for controlling vehicle functions for a vehicle occupant after an accident.

[0012] The single figure shows, in an exemplary and highly simplified manner, a vehicle 1 with a device 2 for controlling vehicle functions for a vehicle occupant after an accident involving vehicle 1.

[0013] It is generally known that many vehicle occupants suffer from post-traumatic stress disorder after experiencing an accident, even if the accident did not result in serious injuries. The accident itself, as a traumatic experience, is often enough to throw those affected off balance. While an automatic emergency call system connected to a rescue service is helpful, it offers less support for stabilizing the vehicle occupants after an accident.

[0014] To reduce the risk of a vehicle occupant developing post-traumatic stress disorder after an accident, the procedure described below is provided.

[0015] Image data captured after the accident by a camera 3 and vital data of the vehicle occupant captured by a mobile data acquisition unit 4, in particular one worn on the vehicle occupant's body, such as a smartwatch or fitness tracker, are transmitted to a control unit 5 of the device 2. Based on the image data and vital data captured after the accident, the control unit 5 determines physiological and / or behavioral data of the vehicle occupant. This physiological and / or behavioral data is then analyzed by means of at least one artificial intelligence-based model stored in the control unit 5 to identify stress, shock, and / or overload indicators in relation to the vehicle occupant.Based on the identified stress and / or shock and / or overload indicators, a psychophysiological state profile of the vehicle occupant is derived and, depending on, in particular on, the severity of the state profile, a light system 6 to output at least one light pattern and / or an audio system 7 to output acoustic signals and / or a display unit 8 to provide safety-relevant information and explanations are automatically activated, in particular to calm and stabilize the vehicle occupant.

[0016] For example, the lighting system 6 can emit a light pattern in colors and gradients that are calming to the vehicle occupant, while the audio system 7 can emit calming music, perhaps music the occupant enjoys. In particular, the information and explanations provided and displayed by the display unit 8, as well as the emitted light pattern and / or acoustic signals, can indicate to the vehicle occupant that all restraint and / or post-crash systems of the vehicle 1 have functioned correctly and that help is on the way.

[0017] Procedures for accident and repair assistance can be adapted to the assessed psychological state of the occupants. Furthermore, explanations regarding the vehicle's safety functions can be provided, particularly via display unit 8, for example: Why did the airbags deploy? Why are the vehicle windows slightly open? etc.

[0018] Furthermore, the procedure provides that an intensity and / or a duration and / or a type of activated vehicle function, i.e. the activated light system 6 and / or the activated audio system 7 and / or the activated display unit 8, is adjusted depending on the determined psychophysiological state profile of the occupant.

[0019] The application of this procedure provides the vehicle occupant with a sense of security, explains vehicle reactions, and supports the vehicle occupant in regaining control and reducing stress reactions during a critical phase after the accident.
