Transportation vehicle, method for a transportation vehicle and communication system for a transportation vehicle

A method for detecting objects in a collision region of a transportation vehicle that is a three-dimensional space surrounding a windowpane or a sliding roof of the transportation vehicle, wherein an actuator is configured to automatically adjust the windowpane or the sliding roof of the transportation vehicle, the method comprising:

• controlling an ultra wide band system of the transportation vehicle to perform object detection based on measurement of channel impulse responses performed by first and second antennas of the ultra wide band system, wherein the channel impulse responses are received by at least one of the first or second antennas in response to transmission of ultra wide band pulses by at least one of the first or second antennas;
• and
• transmitting a signal to the actuator of the transportation vehicle based on a result of the object detection to interrupt the automatic adjustment of the windowpane or the sliding roof of the transportation vehicle,
• wherein at least one of the first or second antennas of the ultra wide band transceiver is controlled to transmit temporally localized transmission pulses with low full width at half maximum, wherein the measurements of the channel impulse responses to the transmitted ultra wide band signals are analyzed to produce time-resolved time-of-flight measurements for object detection that provides positional and temporal resolution of the collision region by comparing a plurality of time-shifted channel impulse responses.

A communication system for a transportation vehicle for communicating detection of objects within a collision region that is a three-dimensional space surrounding a windowpane or a sliding roof of the transportation vehicle to an actuator of the transportation vehicle configured to automatically adjust at the windowpane or the sliding roof of the transportation vehicle, the communication system comprising:

• an ultra wide band system having an ultra wide band transceiver and first, second and third antennas, each of which being configured to send and receive ultra wide band pulses, and
• a computer processor-based controller connected to the ultra wide band system and the actuator, the computer processor-based controller being configured to:
• perform object detection in the collision region by transmitting ultra wide band pulses by at least one of the first or second antennas and based on measurement of channel impulse responses detected by at least one of the first or second antennas for the transmitted ultra wide band pulses, and
• transmit a signal to the actuator based on a result of the object detection to interrupt the automatic adjustment the windowpane or the sliding roof of the transportation vehicle to an actuator for automatically adjusting the windowpane or the sliding roof of the transportation vehicle,
• wherein at least one of the first, second or third antennas of the ultra wide band transceiver is controlled to transmit temporally localized transmission pulses with low full width at half maximum, wherein the measurements of the channel impulse responses to the transmitted ultra wide band signals are analyzed to produce time-resolved time-of-flight measurements for object detection that provides positional and temporal resolution of the collision region by comparing a plurality of time-shifted channel impulse responses.
