Abstract
A method for determining the position and vital signs of an occupant of a transportation vehicle and a transportation vehicle having a radio system and a control unit connected to the radio system. The method is based on channel impulse response (CIR) measurements and is performed using at least two UWB antennas during the operation of the transportation vehicle to determine a position and a vital sign of one or more occupants of the transportation vehicle.
Claims14
A transportation vehicle comprising:
- a radio system with a transceiver with a first Ultra-Wide-Band (UWB) antenna and a second UWB antenna;
- and
- a control unit connected to the radio system, wherein the control unit is configured to control the radio system to determine a position and vital signs of an occupant of a transportation vehicle by actuation of the radio system based on channel impulse response measurements using the first UWB antenna and the second UWB antenna during the operation of the transportation vehicle by determination of the position and a vital sign of the occupant based on a result of the channel impulse response measurements,
- wherein, following detection of an accident of the transportation vehicle, the control unit controls actuation of the radio system to re-perform the determination of the position and vital signs of the transportation vehicle occupant based on new channel impulse response measurements using the first UWB antenna and the second UWB antenna after the accident, and
- wherein the control unit is further configured to determine whether the occupant was ejected from the vehicle as a result of the accident by comparing the detected position and/or the vital sign of the occupant before the accident with the determined position and/or the vital sign of the occupant after the accident.
A method for determining the position and vital signs of an occupant of a transportation vehicle, wherein the transportation vehicle has a radio system with a transceiver with a first Ultra-Wide-Band (UWB) antenna and with a second UWB antenna and a control unit connected to the radio system, the method comprising:
- actuating the radio system based on channel impulse response measurements using the first UWB antenna and the second UWB antenna during the operation of the transportation vehicle;
- determining the position and a vital sign of the occupant based on a result of the Channel Impulse Response (CIR) measurements;
- following detection of an accident of the transportation vehicle, actuating the radio system to re-perform the actuation and determination of the position and the vital sign of the occupant based on new channel impulse response measurements using the first UWB antenna and the second UWB antenna after the accident;
- and
- determining whether the occupant was ejected from the vehicle as a result of the accident by comparing the detected position and/or the vital sign of the occupant before the accident with the determined position and/or the vital sign of the occupant after the accident.
