Marking object arrangeable at a child seat for adaptive actuation of an airbag, method to determine a position and/or orientation of a child seat relative to a car seat and computer program for adaptive actuation of an airbag

A method for determining at least one of a position or an orientation of a vehicle child seat in relation to a vehicle seat, the method comprising:

• placing a marking object on the vehicle child seat, wherein the marking object comprises at least one of a Quick Response code, a radar reflector, a lidar reflector, or an infrared reflector, and wherein the marking object is configured to reflect electromagnetic radiation and mark the at least one of the position or the orientation of the vehicle child seat in relation to the vehicle seat for at least one interior imaging sensor based on the reflection;
• detecting, by the at least one interior imaging sensor, the at least one of the position or the orientation of the vehicle child seat by means of the marking object;
• sending the detection to a control unit for an airbag;
• and
• actuating, by the control unit, the airbag depending on the at least one of the position or the orientation of the vehicle child seat.

An interior monitoring system comprising:

• at least one imaging sensor configured to:
• detect at least one of a position or an orientation of a vehicle child seat by means of a marking object;
• wherein the marking object comprises at least one of a Quick Response code, a radar reflector, a lidar reflector, or an infrared reflector placed on the vehicle child seat, and wherein the marking object is configured to reflect electromagnetic radiation and mark the at least one of the position or the orientation of the vehicle child seat in relation to the vehicle seat for the at least one imaging sensor based on the reflection;
• at least one interface to a control unit for an airbag, configured to send the detection to the control unit for the airbag, wherein the control unit for the airbag is configured to actuate the airbag depending on the at least one of the position or the orientation of the vehicle child seat.

A non-transitory computer readable medium configured to store thereon a computer program for adaptive actuation of an airbag that, when executed by at least one processing device of an interior monitoring system, the interior monitoring system comprising at least one imaging sensor, at least one interface to a control unit for an airbag, and the control unit for the airbag, cause the interior monitoring system to perform a method comprising:

• detecting, by the at least one imaging sensor, at least one of a position or an orientation of a vehicle child seat by means of a marking object, wherein the marking object comprises at least one of a Quick Response code, a radar reflector, a lidar reflector, or an infrared reflector placed on the vehicle child seat, and wherein the marking object is configured to reflect electromagnetic radiation and mark the at least one of the position or the orientation of the vehicle child seat in relation to the vehicle seat for at least one interior imaging sensor based on the reflection;
• sending the detection to the control unit for the airbag;
• and
• actuating, by the control unit, the airbag depending on the at least one of the position or the orientation of the vehicle child seat.
